Can pompholyx (dyshidrotic eczema) be caused by nickel in guitar strings?

What is pompholyx? Pompholyx is a form of hand/foot ,eczema, characterised by vesicles or bullae (blisters). It is a form of vesicular dermatitis of hands and feet, also called vesicular endogenous eczema, and may be the same condition as dyshidrotic eczema. It is sometimes subclassified as cheiropompholyx (hands) and pedopompholyx (feet). Who gets pompholyx? Pompholyx most often affects young adults. It is more common in females than males. Many of them report palmoplantar ,hyperhidrosis,. There is a personal or family history of ,atopic eczema, in 50%. What causes pompholyx? Pompholyx is multifactorial. In many cases it appears to be related to sweating, as flares often occur during hot weather, humid conditions, or following emotional upset. Other contributing factors include: Genetics Contact with irritants, such as water, detergents, solvents and friction Association with ,contact allergy to nickel, and other ,allergens Inflammatory dermatophyte (,tinea,) infections (when it is known as a ,dermatophytid,) Adverse reaction to drugs, most often ,immunoglobulin therapy What are the clinical features of pompholyx? Pompholyx presents as recurrent crops of deep-seated blisters on the palms and soles. They cause intense itch and/or a burning sensation. The blisters peel off and the skin then appears red, dry and has painful fissures (cracks). When involving the distal finger adjacent or proximal to the nail fold, it can result in ,paronychia, (nail fold swelling) and ,nail dystrophy, with irregular pitting and ridges. Pompholyx More images of ,pompholyx, ... What are the complications of pompholyx? Secondary bacterial infection with ,Staphylococcus aureus, and/or ,Streptococcus pyogenes, is common in pompholyx, and results in pain, swelling and pustules on the hands and feet. Infected pompholyx How is pompholyx diagnosed? The clinical presentation is typical. If suspicious of a fungal infection (,tinea pedis,), skin scrapings should be taken for mycology. Patch testing, is indicated in chronic or atypical cases. Skin biopsy, is rarely necessary. It shows spongiotic eczema. Aggravating factors As in other forms of ,hand dermatitis,, pompholyx is aggravated by contact with irritants such as water, detergents and solvents. Contact with them must be avoided as much as possible and protective ,gloves, worn to prevent additional ,irritant contact dermatitis,. People with pompholyx that are found to be allergic to ,nickel, must try to avoid touching nickel items. What is the treatment for pompholyx? Pompholyx is challenging to treat. Topical therapy is relatively ineffective because of the thick horny layer of skin of palms and soles. General measures Wet dressings to dry up blisters, using dilute ,potassium permanganate,, aluminium acetate or acetic acid Cold packs Soothing ,emollient, lotions and creams Potent antiperspirants applied to palms and soles at night Protective ,gloves, should be worn when doing wet or dirty work Well-fitting footwear, with 2 pairs of socks to absorb sweat and reduce friction Prescription medicines Ultrapotent ,topical corticosteroid creams, applied to new blisters under occlusion, and ointments applied during the inflamed dry phase Short courses of ,systemic corticosteroids,, eg prednisone or prednisolone, for flare-ups Oral antistaphylococcal ,antibiotics, for secondary infection Topical and ,oral antifungal agents, for confirmed ,dermatophyte infection In patients with ,hyperhidrosis,, probanthine or oxybutynin is worth trying. In severe cases, ,immune modulating medicines, are indicated. These include: ,methotrexate,, ,mycophenolate mofetil,, ,azathioprine, and ciclosporin. Where available, alitretinoin is used for resistant chronic disease. Other options Superficial radiotherapy Botulinum toxin injections, (to prevent sweating) Phototherapy, and photochemotherapy (,PUVA,) therapy What is the outlook for pompholyx? Pompholyx generally gradually subsides and resolves spontaneously. It may recur in hot weather or after a period of ,stress,, and in some patients is recalcitrant. A type of dermatitis, dyshidrotic eczema is much more common among women. Dyshidrotic eczema, also known as dyshidrosis or pompholyx, is a type of ,eczema, that causes a blistering rash on the hands or feet, especially the fingers, palms, and soles. The blisters are small and often very itchy. Dyshidrotic eczema is the third most common dermatitis, or inflammation, of the hands. It's twice as common in women as men. About half of those who suffer from dyshidrotic eczema also have atopic dermatitis, a common form of eczema. Dyshidrotic eczema is also a side effect of intravenous immunoglobulin infusions (IVIG), which are typically used to treat certain immune system diseases. Symptoms of Dyshidrotic Eczema The characteristic blisters of this condition are: Small, similar to grains of tapioca Filled with clear fluid In clusters between your fingers and toes or on the edges of your fingers, toes, palms, or soles Very itchy and sometimes painful The blisters usually dry and peel in about three weeks. The skin beneath them may be scaly, red, cracked, and painful. Causes The cause of dyshidotric eczema is unknown, but more than one factor is likely involved. It may occur along with atopic dermatitis or hay fever, flaring seasonally along with any ,allergies, you may have. About 40 percent of people with this skin condition are also troubled with hands or feet that perspire heavily. Dyshidrotic eczema is more likely to occur if you: Are under stress Have atopic dermatitis Have sensitive skin in general Have allergies, including hay fever Wash your hands frequently or your hands are often in water Work with cement Expose your hands to metals, such as chromium, cobalt, or nickel Receive intravenous immunoglobulin infusions to treat another medical condition Diagnosing Dyshidotric Eczema Your healthcare provider can usually diagnose dyshidrotic eczema simply by visually examining the rash. A biopsy isn't always necessary, but it can rule out ,psoriasis,and a fungal infection. You may have an allergy patch test to determine if an allergy is involved. Home Remedies The most effective treatment for mild or moderate dyshidotric eczema is to moisturize your hands or feet with a lotion, cream, or ointment, such as petroleum jelly. The moisturizer you use should be free of fragrance, dyes, or alcohol. If allergies are the cause, an over-the-counter (OTC) oral antihistamine should offer some relief. For itching, try an OTC topical corticosteroid cream (also called a topical steroid or topical cortisone cream), cold compresses, or applications of witch hazel. Treatment for Dyshidotric Eczema When self-care doesn't resolve dyshidrotic eczema, your doctor may prescribe a topical cream, such as ,tacrolimus, or ,pimecrolimus,, which suppresses your immune system response. If your skin condition is severe, your healthcare provider also may prescribe steroid pills, coal tar preparations, phototherapy, or a combination of these. Complications If you scratch excessively, your skin may become thick or hard, which makes treatment more difficult. Constant scratching also tears the skin, increasing the risk of skin infection. In severe cases, when you have a lot of pain, use of your hands or feet may be limited. There is no cure for dyshidotric eczema, and it may reappear on a regular basis over the course of weeks, months, or years. What is nickel allergy? Nickel allergy is one of the most common causes of ,contact allergic dermatitis,. In affected individuals, ,dermatitis, (also called eczema) develops in places where nickel-containing metal is touching the skin. The most common sites for nickel dermatitis are the earlobes (from earrings), the wrists (from a watch strap) and the lower abdomen (from a jeans stud); the affected areas become intensely itchy and may become red and blistered (acute dermatitis) or dry, thickened and pigmented (chronic dermatitis). Who is affected by nickel allergy? Contact allergic dermatitis to nickel may develop at any age and in males and females. Once this nickel allergy has developed, it persists for many years, often life-long. Nickel allergy is more common in women, probably because they are more likely to have piercings than men, although this is changing. The degree of allergy varies. Some people develop dermatitis from even brief contact with nickel-containing items, while others break out only after many years of skin contact with nickel. Can nickel allergy affect areas that are not in contact with metal? This has been debated by dermatologists. Some people develop intermittent or persistent eczema on their hands and feet. It is usually a blistering type of eczema, known as ,pompholyx, or dyshidrotic ,hand dermatitis,. Sometimes it is due to contact with metal items containing nickel, but often there is no obvious reason for it. It has been suggested that in nickel allergic people pompholyx may be due to nickel in the diet. Unfortunately it is not possible to avoid ingesting nickel as it is present in most foodstuffs. A ,low-nickel diet, is only rarely helpful. Nickel dermatitis How is nickel allergy diagnosed? Nickel allergy is diagnosed by the clinical history and by special allergy tests, ,patch tests. Subjects undergoing ,baseline series patch tests, are specifically tested to nickel sulphate-hexahydrate. The chemical formula for this is NiO 4 S.6H 2 O. What is the treatment for nickel allergy? Treatment is often necessary for nickel dermatitis. Compresses, Dry up blisters with diluted vinegar compresses. Do not use these if the skin is dry. Topical steroids, Apply topical steroid to the dermatitis as directed by your doctor. Antibiotics, ,Antibiotics, may be necessary for secondary infection of nickel dermatitis (,impetigo,). Emollients, Apply soothing ,emollient, creams frequently to relieve itch and dry skin. Unfortunately, desensitization with injections or pills is not possible so the allergy tends to persist long-term. Avoid skin contact with nickel It is essential to avoid skin contact with nickel-containing metals. Test your metal items Test your metal items to see if they contain nickel. Obtain a nickel-testing kit from your dermatologist, pharmacist or online supplier. The kit consists of two small bottles of clear fluid; one contains dimethylglyoxime and the other ammonium hydroxide. When mixed together in the presence of nickel, a pink colour results. Apply a drop from each bottle on to the metal item to be tested – first try it on a coin. Use a cotton bud to rub gently – observe the colour on the bud. If it remains clear, the item has no free nickel and will not cause dermatitis. If it is pink it contains nickel and may cause dermatitis if the metal touches your skin. The chemicals will not harm your jewellery. Jewellery Necklaces, necklace-clips, earrings, bracelets, watch-straps and rings may contain nickel. "Hypoallergenic" stainless steel, solid gold (12 carat or more) and silver jewellery should be safe. Nine-carat gold and white gold contain nickel. Plastic covers for earring studs can be obtained. Coating the stud with nail varnish is not recommended as the varnish soon chips off. Nickel in clothing Metal zips, bra hooks, suspender clips, hair-pins, buttons, studs, spectacle frames etc. are likely to contain nickel. Use substitutes made of plastic, coated or painted metal or some other material. Nickel in personal articles Personal items with nickel that may touch the skin causing dermatitis include mobile phones, ,lipstick, holders, powder compacts, handbag catches, cigarette lighters, razors, keys, key rings, knives, and pens. These may sometimes cause dermatitis when they are within a pocket. Metal items in the home Cupboard handles, kitchen utensils, cutlery, toaster, metal teapots, scissors, needles, pins, thimble, vacuum cleaners, torches, bath plugs and many other items may contain nickel. Choose tools with plastic handles. Stainless steel does not usually cause dermatitis unless it is nickel-plated. Money Silver-coloured coins are composed of cupro-nickel. Cashiers with nickel allergy may develop hand dermatitis from this source. Wear ,gloves, to handle money or pay with a credit card or cheque. Metal at work Nickel dermatitis may be aggravated by contact with paper clips, typewriter keys, instruments, metal fragments from a lathe or chain saw. Low nickel diet This diet low in nickel-containing foods has been suggested to patients with severe contact allergy to nickel. Its efficacy is unknown. Nickel cannot be completely avoided from diet. Avoid nickel-plated utensils and metal cooking pots. Avoid drinking the initial flow of water from a metal tap. Foods allowed, Meat, poultry, most fish, eggs, milk, yogurt, cheese, quark, butter, margarine Cereals, bread, flour, rice, pasta Small servings of wholemeal flour, wholegrain cereals, wheat bran and wheatgerm Most vegetables Small servings of beetroot, cabbage, cauliflower, leeks , parsnips, potatoes, spinach Fruit such as bananas, and occasional apples and citrus fruit, raw and stewed Tea, coffee, soft drinks, cordials Foods to avoid, Canned food, especially spaghetti and baked beans Green beans, soya beens, broccoli, peas including split peas, canned vegetables Canned fruit, dried fruit, nuts, oatmeal Cocoa, drinking chocolate, chocolate here link for reference How I Treated My Pompholyx Eczema (Dyshidrotic Dermatitis)

What are some new cool tech products that most people don't know about?

UPDATE: This is a long answer, and it’s been collapsed once for lack of attribution. There is no way to attribute the findings contained herein, as they are all my own. What you see here is my personal list of interesting inventions and technologies. Some of them I found through my work, others I found in the technology and new-gadget press over the years. Some, in fact, my wife bought for me. All of these are items I have either personally tried, had experience with or read about on the same pages I link to for each item, and I receive no compensation, perks or attention for having compiled them. As Malcolm Gladwell described in his book ‘,The Tipping Point,,’ there is a type of person, whom Gladwell calls a ‘maven,’ who collects information and from whom others get said information. I have been informed that I fit this description. This is not an inappropriate attempt at viral advertising, nor is it unattributed research. This is just a Gladwellian maven, industrial engineer and safety manager doing what we do, and my only hope in posting it was that other people, who are or may later face problems these technologies have helped me solve over the years, may also be helped by them. I earn nothing but perhaps an upvote for this, that and the satisfaction that my amusing little gadget-list may help, or at least amuse, my fellow humans. After all, I’m an engineer. Collecting gadgets is one of our favorite activities. The Toolbox The best multimeter ever – ,Mooshimeter Most multimeters are the size of wallet or a book, and can only display information in a string of digits. You must be within a foot or two of what you want to measure, have three hands, and the meter can’t save the information it displays any better than binoculars can. The Mooshimeter changes all that. It’s a bit smaller than a normal meter, runs for six months on two AA batteries and connects wirelessly to your cell phone. This means you can tuck it under the hood of your car and monitor that finicky electrical hiccup while driving down the highway at eighty miles per hour. It also records up to six months of data, so you could record voltage and current (yes, both at once) on a given circuit breaker to compare spring vs summer AC usage at home. The auto ranging display also makes diagnostics much simpler by showing complicated information in a simple graphical format. Take a look at the link above to see all the details. Armored heat seeing cellphone – ,Cat S60 -This phone is does everything you expect a good Android phone to do, and so much more. If the Nexus series phones were a team of trendy sedans, the S60 would be a mad max armored truck. It can survive a six foot drop onto concrete and a one hour swim in the 16ft deep end of the pool. This thing can literally see in the dark; not night vision or by amplified star light, no, it see’s the heat emitted by everything around it. Animals in the dark, overheated machinery in a factory, hot water pipes hidden behind a wall, they literally glow in the S60s thermal camera. If you work with your hands it doesn’t take long to find uses for this technology. Handyman? See drafts and missing insulation through walls, trace water pipes, check for overheated circuits in a breaker box and find out where that infernal drip of cold water is coming from. Police officer? See which cars have been driven recently by their glow and track suspects in total darkness by body heat and the hand prints they leave whenever they touch something. Parent? Find your daughters pet when they get lost in the woods or hide in the crawlspace. Take your sons temperature when he’s sick or help him get the oven temperature right to bake cookies. Radiation detecting wrist watch ,$250 This is a Russian made watch called the ,Polimaster PM1208, with a built in geiger counter that warns you when you’re exposed to nuclear radiation. The alarm option keeps the watch silent until there is something dangerous to report, and it also has a counter mode that chirps with every detection. It’s sold with different cases ranging from $200 to $550. A good gadget to wear if you work around radiation or are worried about otherwise undetectable and deadly radiation. Steel wire banding tool strong enough to clamp a hydraulic hose on – ,Clamp tight Clamp tight is like having hundreds of high quality stainless steel hose clamps, zip ties, and fasteners of every time, yet still it still fits in your toolbox. This thing was developed for use on ocean sailing boats as there tend to be very few hardware stores floating out at sea, and boats break down like everything else. To use it, you wrap the wire around the piece to be secured, then around the tool. Turning the bolt pulls the slack out of the wire then rotating the tool locks the wire down like a giant copy of the wire tie that holds a bread bag closed. It does have one obvious weaknesses – you have to have enough clearance to rotate the tool, so some automotive repairs are out of the question because there just isn’t enough room. Overall though, it would be tough to find a more compact and lighter way to repair so many different breakdowns. Nice self-contained butane soldering iron the size of a highlighter – ,Weller, $50 I can’t vouch for this one personally, but a small reliable iron that heats up in seconds and can be used on no notice anywhere it’s needed is a huge help. How often have you needed an iron, but not had a ready plug and stand for it where you were working under the dashboard of the car? 1000 lumen, rechargeable flashlight by ,Nitecore, $55 Growing up, ‘flashlight’ was a word that meant ‘that big heavy plastic thing we keep in the kitchen drawer that glows a dim yellow and always has dead batteries when we need it’. No more. Nitecore makes a variety of good lights, but this is the one I keep clipped to the lip of my pocket. Because I work with my hands, I like to be able to see what I’m working on, and ,very, few things break down in the middle of a well lit work bench in the garage. When something needs attention, it always seems to be at night, up underneath a dashboard, deep in a computer cabinet, or some similar difficult to see location. Since I got this light I’ve never had trouble seeing what I’m doing. It has the usual high/medium/low settings with some flashing options for emergency use, and when I need everything it can do, 1000 lumens is as bright as two car headlights. The battery usually goes a month or two between charges, and any 18650 charger can recharge it in a few hours. $300 CNC Laser cutter/etcher ,tool These $300 laser cutters have become available recently on Ebay, and they offer remarkable utility at a very reasonable price. Various ,reviews, are available; the user interface takes some getting used to, and the mirrors often need alignment after being shipped in from overseas, but after that the cutter will cut and etch words, pictures and just about anything else onto an area the size of printer paper (about 8 by 12 inches). The cutter can be used to make puzzles, pet tags, precision cut wood and plastic, etch metal and glass, etc. A very helpful maker tool. Paper thin microscope lens that sticks to your cell phone - ,Blips The link says it all – this thin slip of plastic the size of a post-it note will turn your cell phone camera into a microscope. Useful for outdoor adventurers, detectives, teachers and anyone else interested in the world around them. $6.50 tiny pocket telescope you can carry everywhere - ,DX This inexpensive tool weighs next to nothing and is tiny enough to fit in anywhere. Good for tracing wiring in a high ceiling, aircraft or bird watching, hiking, playing spy with the kids, etc. Pipe style building materials that use electrical conduit at $3.50 per 10ft section – ,Maker Pipe There are many build systems that can be used to build anything, but most of them like ,80/20, cost a fortune (think $15 per ft!). Maker pipe uses simple, inexpensive clamps plus cheap 3/4inch electrical conduit to build nearly anything you could imagine. If you need to build anything from carts to furniture to equipment, give this one a look. Must have Chemical identification – ,WISER web site, and ,WISER app, download WISER is a chemical identification book long carried by firefighters who need to quickly find out: “what’s in that burning tanker truck, and what will it do to us?” The book used to cost less than $20, but today the entire program is available for free download as the WISER app. If you ever find yourself facing a mystery chemical spill, do you want to be one of the clueless people wondering what to do, or do you want to be the person who looks up the chemical in the first thirty seconds and tells everyone what it is and what you have to do next? The app is free and will happily wait on your cell phone until you need it; don’t be clueless, be WISER. Industrial and special purpose tools Laser paint scraper and cleaning tool – ,P Laser, and in action ,video An interesting scraping process similar to sand blasting, CO2 blasting and bead blasting. I can’t vouch for this product, but I’ve never seen anything else like it either (as of 2016). MAD ,speakers for extreme distance, volume and clarity Planar speakers, like the ones above are very different from standard paper cone speakers. If normal cone speakers are like light bulbs spreading out in all directions, planar speakers are like lasers. Where cone speakers fade out over distance and interfere with each other, planar speakers can be heard at ridiculous distances, and over other noises. Probably their neatest trick is that in a noisy 90 dB environment, this speaker can clearly be heard an understood even at 80 dB. On site, eco-friendly cleaning and sanitizing liquids from saltwater – ,Pathosans, - ,video - If you use cleaning chemicals in any significant quantity, you need to watch this video and check out this system. Just as your water softener uses salt to remove minerals from your drinking water, this system uses bulk salt and tap water to produce huge quantities of cleaning chemicals and sanitizing liquid on site. The process is simple but clever: electrical current is used to split the salt apart in salt water. Salt (sodium chloride) in water is split and filtered to become sodium water (Patho clean) and chloride water (Patho sans). Patho clean is good for scrubbing carpets, washing surfaces, etc while Patho sans kills germs wherever it goes. Agricultural companies use Pathosans units to sterilize live animal contact surfaces and hotel chains use it to produce cheap and effective cleaning products. The cost of the cleaner and sanitizer is around five cents per gallon. The machine itself commands a high price, but if your business buys its cleaner/sterilizer in 55 gallon drums, this system stands a good chance of saving you a lot of money. Wave glider,, an ocean drone that can cross oceans and is powered by wave action These inventors figured out that while waves make the surface of the water go up and down, they have zero effect on the deeper water. The torpedo shaped bottom has fins that ratchet it forward every time it’s hauled up and down by the surface drone bobbing on the waves above. They work in very small waves and category 5 hurricanes equally well and so can be used to take readings, monitor for science/defense, or conceivably to transport illicit cargo from one continent to another. Industrial forklift crash prevention – sees around blind corners and runs on batteries – ,Collision Sentry This handy gadget runs on D batteries and uses magnets to stick to metal racking at blind 90 degree corners. When someone approaches from one side nothing happens, but when someone approaches from both sides simultaneously the device lights up a flashing warning to prevent a collision. Interesting ring knife for people who open a lot of packages – ,Handy Safety Knife This product is intended for people who use hand knives to open a lot of packages. It is inexpensive, disposable, and always to hand. There are plenty of places these would be unsuitable (any workplace with powered conveyors or equipment comes to mind), but the idea is so unique it deserves to be included for the one person who has the problem this tool answers. Two way radios for $15 instead of $300, – It turns out that two way radios have gotten a lot cheaper over the years, but just as a teenager can charge grandma money to fix her computer, so the contractors that most companies get their radios from are not in a hurry to tell everyone how easy the job has become. BaoFeng radios cost between $15 and $30, and do everything you expect from a walkie-talkie, but unlike what you’re probably using now, BaoFeng uses better equipment and lithium ion batteries standard. This translates into much longer run times and better performance. The ,simple $15 radio, and ,more complicated $30,radio can be found here, along with the ,cable, used to program them. This link ,here, discusses how to do it. Rust prevention in ,existing concrete structures, courtesy of NASA NASA has a lot of concrete structures near the coast, and saltwater corrosion is a problem for them. So they figured out a way to rust proof metal after it had been encased in concrete for years. If you have any concrete structure that’s showing its age, take a look at this link. The ,Bad AXX, – an improved ax for fire fighters - $250 to $300 This is a Swiss army knife for firefighting: it’s a step up to high windows, it’s a repelling anchor point to get you off the roof when it’s on fire and collapsing, its wrench to shut off gas lines and open fire hydrants, it holds you’re forced entry tool, and the head cuts without ever getting stuck. It’s real and in production – ,check out the video,. Travel A handy power strip for world travel – ,Power donut A power strip that is tiny, travels easily, and adapts to different electrical systems around the world. Medical tools Emergency blood stopping powder, a must have for first aid kits - ,Celox, and ,how to use This product is used to keep someone alive long enough for the ambulance to arrive in the event of severe bleeding. It ,forms a jell, to stop blood flow at the injury and comes as powder packages, bandages, or a syringe full of the powder for gunshot wounds. Pioneered in the US military, this is one of several good haemostatic products that are must haves for any serious first aid kit. If you own a gun or a knife, does it really make sense to be totally unprepared for the results of gun and knife wounds? Emergency blood stopping pack – a second choice after Celox - ,QuikClot, and ,how to use QuickClot stops severe bleeding by absorbing the water out of blood, thus causing the clotting agents to become super concentrated at the injury site and stop the bleeding faster. As with Celox above, this will help keep someone alive long enough for the paramedics to arrive and save them. Liquid band aid – a cheap, generic must have for first aid kits – ,example link This is a generic product for minor to moderate injuries that sterilizes a cut and protects the injury site like a band aid. Good for use on tight locations that flex where band aids wouldn’t work. Because of its utility and tiny size it’s a good addition to any first aid kit. Betadine – inexpensive sanitizing solution for cuts used by EMT’s - ,Link In the old days parents used to use iodine or alcohol to clean and sterilize small cuts and scrapes (hydrogen peroxide will bubble dirt out of a wound, but it does not sterilize). Today we all have access to the same inexpensive product nurses and surgeons use; Betadine. It cleans and sterilizes wounds with much less burning than the old options, and most of us are familiar with it already as the brown skin staining wipe that doctors use before drawing blood. Transcranial Magnetic Stimulation or ,TMS, – a new treatment for depression, OCD, and ,Autism, – ,Related tech TMS is a revolutionary new tool that uses very strong magnetic fields to induce current flows near the surface of the brain. It’s essentially a big capacitor bank and a hand held coil employed for ten to twenty minute sessions to treat Depression and other mental conditions. Its painless, has virtually no side effects and is FDA cleared for a few conditions, but it’s in its infancy as a treatment. Promising studies have shown its potential to improve OCD, Autism and several other conditions. Ultrasound for your cell phone – production pending - ,Clarius For those trained to use it, Clarius is a new handheld ultrasound probe that allows diagnostic procedures to be done anywhere you have a cell phone. Production is slated to being in 2018. Tech off the grid Clean burning hyper efficient ,cook stove, – ,see video The Aprovecho Research center designs and sells extremely efficient cook stoves for camping and long term use in the third world. These stoves have a core made from lightweight clay that reflects heat back into the fire box, allowing a few sticks and twigs to burn hot and clean with no smoke. The top of the stove is built to channel the hot gasses onto the cooking pot for maximum heat transfer with minimal fuel. To first world campers this translates into a neat (if heavy) stove that can burn almost any handy material to boil water and cook. For church groups and other organizations working in the third world these stoves are a way to ,drastically, reduce expenditures of time and money on fuel for cooking – ,see video,. For large orders, the stoves can be shipped in by cargo canister at prices as low as $5 a stove for the bare clay core that actually makes the unit work. Anyone that has to think about where their cooking fuel comes from could benefit from this technology. A light that runs on gravity like a grandfather clock – ,Gravity light Gravity light is a small generator that uses a sack full or rocks to produce electricity for simple indoor lighting. Just like a grandfather clock, as the weights descend their energy turns the mechanism, in this case turning a generator to drive the lights. While campers can use this product, it is intended for the third world where indoor lighting after dark means kids can learn to read and go to school. Anyone living without electricity could benefit from this product. One way to internet everywhere – ,Outernet, – ,See video Outernet is the best of the internet, broadcast one way only to earth from a satellite. The ‘Lighthouse’ model mounts to a standard direct TV dish and downloads many MB of data per day, while the ‘Lantern’ is a portable solar powered device that can travel anywhere and downloads at a slower rate. Both access the same information such as educational materials for students, warnings about local emergencies, weather forecasts, censorship free news, etc. Outernet devices slowly download this information and then allow users to log in and browse what is stored locally. The downside is that the data flow is one way only, but the upside is the system works as an end run around missing power and data infrastructure as well as censorship rules. Clean drinking water from any source - ,Lifestraw Access to safe drinking water is essential to health, and many of the worst diseases spread via contaminated water. The lifestraw family of products is invaluable to hikers and those working in the third world because it allows anyone to turn dirty water into clean safe water. The absence of safe water doesn’t just kill and sicken people, it drags down their finances, ensuring that those in crushing poverty stay there caring for the sick rather than using that time and money to send children to school. Freshwater from saltwater – the ,water cone,. A simple plastic cone that makes 1.5Lts of freshwater from saltwater. Water transportation from river to home – ,Water wheel In some areas of the world, even getting water to the home for cooking and bathing is a major job that pulls time away from education and other productive tasks. The water wheel cuts that time in half and improves quality of life. Fold-a-scope The one dollar paper microscope that fits in your pocket and is ,good enough for lab tests,.

Parents corner $100 Life saving product to prevent SIDS in infants - ,Snuza Hero, - If you or someone you know has a child under a year old, this is the most important thing on this page. The Snuza Hero clips onto an infant’s diaper to monitor motion and breathing. If no movement or breathing is detected for 15 seconds the device vibrates to wake the baby, but if nothing is detected by 20 seconds it sets of a loud alarm. When SIDS kills a baby, all too often it happens in the middle of the night when both parents are asleep and it’s completely silent. Without some kind of alarm it’s almost impossible to intervene in time, so this can be the most important $100 spent on your baby. It saved our daughter’s life, and a quick read through the product reviews shows many more parents with similar saves. Kingii flotation wrist band, $90 After losing a relative to drowning, this engineer designed a wrist band that uses common CO2 cylinders to inflate an air bag for emergency flotation. Unlike a bulky life vest, this thing can be worn easily in or around water, and if used in an emergency it can be easily repacked and reloaded after saving a life. It’s suitable for kids and adults, and easy insurance when working around treacherous bodies of water. Roughly 372,000 people drown every year, and $90 seems a small price to protect those you care about. Wetsuits for kids, $35 Most kids love the water, but little little kids inevitably end up shivering and cold even at indoor pools that are comfortable for adults. The problem is that children have lots of surface area to lose heat through, but very little volume, meaning they get cold very quickly and can’t swim as long as they’d like. A wetsuit ,like this one, fixes that problem and drastically reduces the area needing sunscreen as well. If you’d like to guarantee your child sleeps soundly through the night, consider one of these to turn a one hour trip into a real afternoon outing. Free math and school tutoring - ,Khan academy, - ,promo video Khan Academy helps anyone at any level learn about math, science, and a variety of other school subjects using recorded lectures by skilled professors combined with interactive tests and automated tutoring. It’s hard to oversell this site; everything is free to use, nearly all subjects are covered, you can log in as a student, parent or teacher to monitor progress, and the site even has test prep for all the major tests like SAT and MCAT. The math section that started the site is particularly clever – when a student first logs in they take a ten question test that helps the program figure out their skill level, and then it suggests new math topics and tracks progress while periodically refreshing old topics as well. If you know anyone in school as a student, parent or teacher, tell them about this program. ,Odds are good they’ll thank you for it,. The drug talk – “,Licit and Illicit Drugs by consumer reports,” The do’s and don’ts of drugs are usually right up there with the ‘sex talk’ when it comes to uncomfortable conversations parents really need to get right, but often put off or miss altogether. Fortunately, consumer reports wrote an excellent book on the topic which is available for free online. The organization has a well earned reputation for impartiality, and it shows as the book talks about what each drug does, how it was discovered, and how it got to be legal or illegal. Having the facts makes smart choices possible, and this free resource is a must read for anyone over ten. $1.25 calculator wrist watch loved by grade school kids – ,Link Kids 5th grade and younger find these to be the height of fashion and prestige. If you want to reward a child with an inexpensive gift that will help them academically, search Google for ‘calculator watch’ and order a few. How to get started in life and live well on less - ,Poorcraft,. Unless you’re lucky enough to start life as a millionaire, most of us have to start out on very small incomes working long hours at unpleasant jobs. There are scams and businesses beyond count built to take advantage of the young and un-educated. If you or someone you know earns less than $50,000 a year, spend $5 and get this book. It’s an easy-to-read graphic novel packed to the brim with useful tricks and tips, plus plenty of humor to keep things interesting. (Cartoon thanks to ,xkcd,) Kerbal Space Program - ,Link This game is a great way to build STEM interest in children and adults as you run a space agency for the ‘Kerbals’ and try to land on the moon or go to mars. All technology in the game also exists in the real world, rockets can be built from parts like Lego bricks and all the physics are as close to real as they can make them. Google ,Sky,, ,Moon, and ,Mars, + ,Stuff in space,, ,Impact earth,, ,lightyearFM,, the ,100,000 stars, project and the ,scale of our solar system,. Bit of an astronomy dump here, but if you want to learn about our universe or teach your children, these are excellent resources. Google Sky, Moon and Mars let you explore these places in the same way Google earth explores the globe. Stuff in space maps satellites around the world, impact earth simulates asteroid impacts and Lightyear FM travels 100 light years out from earth playing the songs that could be heard at that distance. The 100,000 stars project is an accurate, searchable 3D model of the nearest 100,000 stars to the earth, and the ‘scale of the solar system’ video shows how small we are by building a huge model in the desert. FanFiction.net, and ,Archive of our own (AO3) This is a good way to encourage reading and incentivize writing practice. For any book, movie or TV show, there are fans who write stories about the canon, such as ‘what if she did this?’ or ‘what if this happened this way?’. These works of ‘fan fiction’ can read just like the original work, or can be very different with only characters from the original work. Everyone enjoys some kind of media, and ,FanFiction, is a good way to get them reading about something they already like. In many cases, the instant availability of interesting reading material on any internet capable device boosts reading skills and sets up a situation where writing is undertaken enthusiastically and for fun. We’ve all seen people type out angry rants when ‘someone is wrong on the internet’. Fan fiction sets up situations where the reader will find a story about characters they’re very invested in and say ‘This story is awful! I could write a better story that this!’. And they do. And the posted story gets comments about what the bran-new author needs to work on. And so they write some more to show them, show them all. After several months the same student who had to be forced to write a three page paper will be feverishly banging out ten page chapters twice a month to keep their fans happy. NSF test The National Science Foundation periodically surveys the public to see what they know about science, and the results usually aren’t pretty. The link above is to the ten question NSF test and a series of answers, essentially a canned lesson plan for anyone running a science class at any grade level. The printed test fits on a single sheet of paper and can be used to quickly find out how much your students know and catch up those who have holes in their understanding. +Chemistry article referencing the ,periodic table, and ,nuclear table How different ,engines work Anyone teaching STEM classes or with an interest in engines may find these animated diagrams useful. They’re not the most detailed, but they cover many different basic types of engines. ,This link, shows the standard four cylinder auto engine in more detail. And this link shows more of the peripheral systems like cooling. ,Mechanical link,. Scan expensive text books or digitize your library – ,CZUR scanner CZUR is a $300 machine that connects to any computer and scans books into e-books. Scanners that automatically turn the pages cost more than a luxury car, so this unit is an inexpensive way to digitize pricey school textbooks, unusual books from your library, or just anything you want to read but don’t feel like lugging around in paperback. Speed is about one photo (which covers two pages of the open book) per two seconds, so a 300 page book will take about eight to ten minutes to scan. If your college still uses paper text books, consider spending the $300 once on the scanner, instead of two or three times a year at the bookstore. Bizarre wheels for projects, forklifts and robots – ,Mecanum Wheel Mecanum Wheels are wheels that allow a vehicle to slide sideways by counter-rotating its wheels. They’re used on forklifts that work in narrow aisles, and in other specialty applications. Anyone building a wheeled robot for a competition should be aware of these because of the performance edge they provide. Fun projects The ,Long Now, foundation building a ,clock, that will run for 10,000 years. The long now is a society dedicated to long term thinking, which involves several projects including a four story tall stainless steel clock that will run for 10,000 years, a project to record all human languages, and another to record old computer operating systems for backwards compatibility. Hundred year ,time capsule for a dollar A simple article on how to build a time capsule from a wine bottle that will last for one hundred years or more. This is a quick afternoon project that lets anyone from grade school kids to adults send a message to people decades or centuries in the future. Free satellite TV for $250 of ,equipment It turns out that free to air satellite TV is still around, and $250 worth of equipment will get you everything you need to watch it. This is a Ku band system (think direct TV sized) and mounts anywhere with a clear view of the southern sky. The programs are a mishmash of low budget shows and international content, but there are hundreds of channels, and they work anywhere you can see the sky. This package is understandably popular with members of the armed forces who want access to their own TV programming while stationed abroad. They also sell the old huge C band dish systems (8 ft across and larger) that still pick up content as well as direct downlink video received by news trucks. Programming varies wildly, but there are some reliable shows – Nebraska, for example, broadcasts their PBS stations down on C band. Telecom – ,how antennas work, + ,satellite coverage map, + ,how bandwidth works,+ ,KU vs C band pro con, + Jumping shoes that give 6 ft of air – ,Kangaroo shoes Know as ‘acro stilts’, ‘power striders’ or ‘kangaroo shoes’, these toys allow for ,ridiculous jumps and let anyone run faster than the world’s fastest sprinter,. They use a composite spring very much like the flexible part of a compound bow and arrow to greatly increase the efficiency of running and jumping, and like skate boarders, are popular for the tricks skilled users do with them. Kniterate, – a $5000 automatic knitting machine / cloth printer For those who do serious amounts of knitting or want to design their own clothes, this home machine allows you to program and create whatever you want from common yarn. Seaboard, – a $2000 to $9000 ,keyboard, with silicone keys that let you bend musical notes while you play. Software defined radio – see and hear everything on every channel with this ,thumb stick We all know AM and FM radio from cars, and some know more types of radio like citizens band, ham radio, etc, but until recently, receiving on more than one channel required many different radios. Not anymore. ,Software defined radio, uses a computer to translate the signal, and this model costs $25, is the size of thumb drive, yet can receive anything from 500 Kh up to 1.7 Gh. In automotive terms, this would be like a car that could fly, drive, float on the water, dive under the water, rocket into space, yet it fit in your back pocket and cost $25. If you’ve ever thought about dabbling with radio, it’s never been cheaper or easier than this. A bee hive that ,dispenses honey through a tap, – no mess, simple and easy. Not something I ever thought about before seeing this, but smoking out bees and opening up a hive of angry stinging insects isn’t the easiest way to get honey, especially considering the resulting comb still has to be scraped and filtered. These guys figured out how to get bees to fill an artificial honeycomb with honey, and it can literally be emptied with a tap. Learn to knit… ,steel rings, into medieval body armor – ,ringlord.com Anyone into the ,SCA, may find this old news, but some people still make armor and jewelry out of steel rings called chainmail. This site sells everything necessary to weave just about anything you want to make. Incredibly powerful magnets designed for particle accelerators – ,United Nuclear For all your incredibly powerful magnet needs. These magnets were intended for use in physics labs, and while prices range from $80 to $200, they are strong enough to amputate an arm if careful handling is not used. Magnetic wedding rings for magicians – ,Super magnet man These magnetic rings look and feel like normal jewelry, but can be used in magic acts. I have been informed that it is theoretically possible for a cashier to use one to demagnetize a particularly abusive or obnoxious customer’s debit card, though I don’t know of anyone who has. While there are many potential applications, take care not to touch your wallet while wearing one. Multitool business card – about $1 per card to be remembered by clients/employers – ,Card, + ,Label, (Avery 5317) Business cards tend to lead short lives, but they don’t have to. The listed multitools are the size of business cards, yet they can perform a variety of useful functions, and with the addition of the linked label, they can easily become unusual, useful business cards. If you think it’s worth one dollar to have a client keep your card in their wallet for the next five years, consider some of these. (My then-fiancee made my first batch for me as a college graduation present. Not only have they proved impressive for networking and business purposes, but my wife still designs all my business stationery.) Gallium, – the inexpensive liquid metal that turns aluminum to mush. This one is largely self-explanatory – ,got something aluminum you don’t want in one piece anymore,? Try Gallium! Ultimate privacy monitor – no one can see your computer screen but you! – ,Hack how to This clever hack is useful for those who need a privacy monitor. Essentially, all monitors have a thin skin of polarizing plastic in the display to produce a useable image. If you take the monitor apart, peel off this layer and apply it to a set of glasses, only the person wearing the glasses can see the screen – everyone else just sees a blank white light. Millennium-Disk or M-Disk ,$5 a disk,, ,$50 for the burner drive An M disk is a CD, DVD, or Blue ray disk made from a stone like material that will read in any conventional drive but ,retains its data for 1000 years,. Most disk media becomes unreadable after a few years of storage, and the same holds true for magnetic hard drives and solid state drives like thumb sticks. Up till recently there wasn’t any way to preserve digital material short of constantly transferring it from one machine to another. Now it’s possible to send video and photos into the future through time capsules, well wishes with our lost loved ones through coffins, or just archive important documents for years to come. What do you want the world to remember when you’re gone? Home, construction and architecture Buy a $2000 cargo/shipping container for an indestructible backyard shed - ,Link Cargo canisters are ugly but very durable and less expensive than most methods of construction. Suitable for backyard sheds, or even as the basis for tiny homes and ,larger structures,, it can be useful to know this is an option. Color changing heat sensitive tile for showers – ,Moving color Most of us have seen that black plastic that changes color like a mood ring when held in a warm hand. It turns out someone made them into bathroom tiles that change from black to a rainbow of vibrant colors when the hot water comes on. In ,floor heating tubes, for very cheap winter solar heating (no solar cells needed) If you ever build your own home, remember this trick. Home heating is usually done with forced air through ducts, but this requires a very small area to be very hot (the firebox of the furnace). We all know burning gas and oil gets expensive, but most of the time it’s our only option; solar concentrators can heat water to 150 degrees F, or even 180, but they can’t approach the high temperatures needed for a forced air furnace firebox. However, if you cast plastic water tubing into the floor of the building when its being built, now you have a very larger area that only needs to be warm in order to heat the whole house. A ,solar hot water panel, made up of black copper pipe encased in vacuum tubes can be hooked directly to the system to heat your entire house for free even in the dead of winter. ICF (,Insulated Concrete Forms,) are lego blocks for building concrete homes (,watch a one day build,) For anyone building a new home, ICF blocks are a great way to increase build speed, lower cost, improve insulations and finish with a much stronger structure than a wood only build would provide. To quote some statistics, a home build with ICF blocks can save 70% on energy bills, lower insurances costs by 10%, has 75% less outside air infiltration, is 10 times stronger and 3 times quieter than a wood home, comes with a 4 hour fire rating is literally ,bullet proof,! ,Floor example,. ,Roof example,. Hunting, ballistics and security related Z-Modo home ,camera system Trying to secure a home or business is never easy; almost by definition anything that gets broken/stolen happens when you aren’t looking. An eight camera system with DVR is a good fix for this, and Z-Modo makes many fine systems for around $200 to $300. Have you ever heard of a break-in that cost less than $300? Normally when you find out about a break in it’s far too late to intervene, and in most jurisdictions the police need three to six months to get the results back on a fingerprint search, and that’s assuming there are prints to find and the person leaving them already has a record with prints to search for. If someone gave you an assignment at your job would you still remember three months later? By contrast, an eight camera system deters some break ins, and if a break in does occur, it preserves video of everything that is taken, and everyone involved. The police normally have a pretty good feel for who is causing problems in a neighborhood, but can’t do much about it without clear evidence. With a camera system you can run the video back while you wait for the police to arrive, and then play them the video with everyone’s faces. Quite often the result is “Hey, I know that guy! Wait here while we go pay him a visit.” In this way a camera system can permanently remove bad actors from a neighborhood and help everyone sleep better. Krav Maga This is an unarmed combat system developed by what became the ,Israeli army, to deal with ,NAZIs, in the 1930s. This is not a ‘martial art’ full of training dances and karate chops against empty air, it’s a way to ,take down an attacker trying to kill/rape you,. It was built to defend an oppressed minority from F-ing ,NAZIs, ,and it works,, so it’s ideal for children, women, and many others. The slingshot channel. Yes, ,this is a thing,. If you want to see things hit by overpowered homemade slingshots built by an engineer/body builder and his wife, take a look. How to build a potato cannon for fun and ballistics demonstrations – ,spud gun, & ,Pumpkin chucking For everyone who ever wondered how to build an air cannon to throw potatoes, here is an expert.

Super compact Taser $300- ,Pulse A recent shooting taser that is a nice mix of small size and functionality. Cheap disposable pepper cannon $40– ,Pepper blaster, - ,test video A tiny but highly effective way to deliver capsaicin to the face as cheaply as possible. While not a firearm, the device uses percussion caps to propel the pepper sludge, meaning it works at any temperature, in the rain in the wind, and doesn’t need to be charged up like a battery or a pressure can. Blackpowder derringer $180– yes ,they still make them An interesting tiny firearm that loads just as it did in the 1850s. World’s smallest full power bow $900– ,Liberty Bow, - ,test video This manufacture figured out that compound bows no longer need the heavy aluminum bar between the spring arms, so they removed it to create a bow with a 70lb draw weight that fits easily in a backpack. Pricy, but interesting. Computer tools Run a ‘who is’ search to find out who owns a website –eg, ,slanted news vs propaganda There are many sites on the web that purport to say something, but are owned by someone who has every reason to lie. A ‘who is’ search is a way to quickly find out who owns the website you’re reading. For example, if a web page claims solar panels cause cancer, a ‘who is’ search might reveal it to be owned by British Petroleum. Find old versions of software to roll back bad updates – ,Old version Sometimes it’s handy to be able to undo a bad software update, or re-install a program for the distant past; Old version allows you to do just that, simply and easily. Google ,Earth, and Google ,Maps, to navigate and explore our world These are known to almost everyone, but on the off chance someone hasn’t heard of Google maps, or its portable 3D parent Google Earth, take a look. Navigation and exploration has never been simpler. Aircraft and pilots Yes, you can ,fly small planes if you want to Aircraft are not solely the domain of the rich and famous. You can buy or build an aircraft for the price of a luxury car, and with a small propeller driven plane, your time is suddenly much more valuable. Draw a circle on a map with your home at the center and a radius of 8 hours driving. That’s about what most of us can do in a weekend; anything outside that circle is out of reach, or requires careful advanced planning. With an aircraft, that circle suddenly grows to 1000 or 2000 miles. Someone living in DC can hop into their plane after 5PM on a Friday and be relaxing on the beach in Florida before the sun sets. Cars and automotive Tesla, model S, X and 3 – The best car ever (as rated by consumer reports). By now most people have heard of Tesla motors and their three production cars, but if you’re one of ,today’s lucky 10,000, then read on. Tesla makes two $50,000 cars – a sedan and an SUV and one $35,000 sedan and they are the safest cars on earth as rated by multiple agencies. And they’re the fastest production cars in existence. And they’re all electric, silent and have a +200 mile range. And they come with autodrive standard, meaning the day self driving cars are legalized in your state, you already own one. Consumer reports has been rating cars for more than fifty years, and not only did the Tesla score higher than any other car or truck ever, they rated it the best car ever. Stories about it abound, like the time an insurance company tried to test the rollover strength of the roof and the car ,broke their hydraulic car crusher,. Automotive ,DashCam, by ‘Boomyours” for $60 This strangely named camera of Russian manufacture is an indispensable tool for any car. When paired with a ,$5 micro SD card and adapter, (not included, must be purchased separately or it won’t run), the camera suction cups to the windshield like a GPS and records everything happening inside the car and visible through the front window. It starts up as soon as the car starts, records about a month of driving, and automatically overwrites the oldest videos so no action is required by the user, just plug it in and forget it. If you are hit by another driver, now you have video of the other person’s mistake and no amount of lawyers can change who is at fault. “It was my fault because I was on my phone? No, actually, the video clearly shows you hit me and I was not on my phone. That, and the GPS and G-force data shows where, when and how hard you hit my car.” In addition to crash uses, the camera also records what happens during a traffic stop, and many users find the police are more polite when they are being recorded. If not, well, you now have video of exactly what happened and YouTube is free. Finally, the micro-SD to SD card adaptor allows you to quickly pull the card after a hit and run, put the video onto the responding officer’s laptop, and show them exactly what happened within minutes of the accident, resulting in an APB and a much higher chance of catching the hit and run driver. RainX, to improve visibility in wet/snowy conditions - $3 bottle lasts for many years Most people already know about RainX, but if you are one of ,today’s lucky 10,000, to whom this is news, then read on. Being able to see while driving is pretty important, and RainX makes the task much easier, especially in hard rain or snow. Basically it’s ,a wax you rub onto your windshield, in two minutes using a paper napkin or whatever you have handy in the car. Just as water beads up and runs off a waxed car, the same thing works on glass. The bottle above doesn’t leak like the spray bottles do, and can be tucked into the door compartment and re-applied every three months or so. One $3 bottle will often outlast the car it’s kept in, and it’s a cheap way to reduce the risk of a road accident. BlueTooth OBD2 car ,diagnostic scanner for $7 This tool links to your Smartphone using the Torque app and allows you to read and reset trouble codes and check engine lights.

What are the best new products or inventions that most people don't know about?

Fair warning, this is going to be a, big, (10 pages) info dump. Just skim the headings and read the discription paragraph if it sounds interesting. The toolbox The best multimeter ever – ,Mooshimeter Most multimeters are the size of wallet or a book, and can only display information in a string of digits. You must be within a foot or two of what you want to measure, have three hands, and the meter can’t save the information it displays any better than binoculars can. The Mooshimeter changes all that. It’s a bit smaller than a normal meter, runs for six months on two AA batteries and connects wirelessly to your cell phone. This means you can tuck it under the hood of your car and monitor that finicky electrical hiccup while driving down the highway at eighty miles per hour. It also records up to six months of data, so you could record voltage and current (yes, both at once) on a given circuit breaker to compare spring vs summer AC usage at home. The auto ranging display also makes diagnostics much simpler by showing complicated information in a simple graphical format. Take a look at the link above to see all the details. - Armored heat seeing cellphone – ,Cat S60 -This phone is does everything you expect a good Android phone to do, and so much more. If the Nexus series phones were a team of trendy sedans, the S60 would be a mad max armored truck. It can survive a six foot drop onto concrete and a one hour swim in the 16ft deep end of the pool. This thing can literally see in the dark; not night vision or by amplified star light, no, it see’s the heat emitted by everything around it. Animals in the dark, overheated machinery in a factory, hot water pipes hidden behind a wall, they literally glow in the S60s thermal camera. If you work with your hands it doesn’t take long to find uses for this technology. Handyman? See drafts and missing insulation through walls, trace water pipes, check for overheated circuits in a breaker box and find out where that infernal drip of cold water is coming from. Police officer? See which cars have been driven recently by their glow and track suspects in total darkness by body heat and the hand prints they leave whenever they touch something. Parent? Find your daughters pet when they get lost in the woods or hide in the crawlspace. Take your sons temperature when he’s sick or help him get the oven temperature right to bake cookies. Steel wire banding tool strong enough to clamp a hydraulic hose on – ,Clamp tight Clamp tight is like having hundreds of high quality stainless steel hose clamps, zip ties, and fasteners of every time, yet still it still fits in your toolbox. This thing was developed for use on ocean sailing boats as there tend to be very few hardware stores floating out at sea, and boats break down like everything else. To use it, you wrap the wire around the piece to be secured, then around the tool. Turning the bolt pulls the slack out of the wire then rotating the tool locks the wire down like a giant copy of the wire tie that holds a bread bag closed. It does have one obvious weaknesses – you have to have enough clearance to rotate the tool, so some automotive repairs are out of the question because there just isn’t enough room. Overall though, it would be tough to find a more compact and lighter way to repair so many different breakdowns. Nice self-contained butane soldering iron the size of a highlighter – ,Weller I can’t vouch for this one personally, but a small reliable iron that heats up in seconds and can be used on no notice anywhere it’s needed is a huge help. How often have you needed an iron, but not had a ready plug and stand for it where you were working under the dashboard of the car? 1000 lumen, rechargeable flashlight by ,Nitecore Growing up, ‘flashlight’ was a word that meant ‘that big heavy plastic thing we keep in the kitchen drawer that glows a dim yellow and always has dead batteries when we need it’. No more. Nitecore makes a variety of good lights, but this is the one I keep clipped to the lip of my pocket. Because I work with my hands, I like to be able to see what I’m working on, and ,very, few things break down in the middle of a well lit work bench in the garage. When something needs attention, it always seems to be at night, up underneath a dashboard, deep in a computer cabinet, or some similar difficult to see location. Since I got this light I’ve never had trouble seeing what I’m doing. It has the usual high/medium/low settings with some flashing options for emergency use, and when I need everything it can do, 1000 lumens is as bright as two car headlights. The battery usually goes a month or two between charges, and any 18650 charger can recharge it in a few hours. $300 CNC Laser cutter/etcher ,tool These $300 laser cutters have become avalible recently on Ebay, and they offer remarkable utility at a very reasonable price. Various ,reviews, are available; the user interface takes some getting used to, and the mirrors often need alignment after being shipped in from overseas, but after that the cutter will cut and etch words, pictures and just about anything else onto an area the size of printer paper (about 8 by 12 inches). The cutter can be used to make puzzles, pet tags, precision cut wood and plastic, etch metal and glass, etc. A very helpful maker tool. Paper thin microscope lens that sticks to your cell phone - ,Blips The link says it all – this thin slip of plastic the size of a post-it note will turn your cell phone camera into a microscope. Useful for outdoor adventurers, detectives, teachers and anyone else interested in the world around them. $6.50 tiny pocket telescope you can carry everywhere - ,DX This inexpensive tool weighs next to nothing and is tiny enough to fit in anywhere. Good for tracing wiring in a high ceiling, aircraft or bird watching, hiking, playing spy with the kids, etc. Pipe style building materials that use electrical conduit at $3.50 per 10ft section – ,Maker Pipe There are many build systems that can be used to build anything, but most of them like ,80/20, cost a fortune (think $15 per ft!). Maker pipe uses simple, inexpensive clamps plus cheap 3/4inch electrical conduit to build nearly anything you could imagine. If you need to build anything from carts to furniture to equipment, give this one a look. Must have Chemical identification – ,WISER web site, and ,WISER app, download WISER is a chemical identification book long carried by firefighters who need to quickly find out: “what’s in that burning tanker truck, and what will it do to us?” The book used to cost less than $20, but today the entire program is available for free download as the WISER app. If you ever find yourself facing a mystery chemical spill, do you want to be one of the clueless people wondering what to do, or do you want to be the person who looks up the chemical in the first thirty seconds and tells everyone what it is and what you have to do next? The app is free and will happily wait on your cell phone until you need it; don’t be clueless, be WISER. Industrial and special purpose tools Laser paint scraper and cleaning tool – ,P Laser, and in action ,video An interesting scraping process similar to sand blasting, CO2 blasting and bead blasting. I can’t vouch for this product, but I’ve never seen anything else like it either (as of 2016). On site, eco-friendly cleaning and sanitizing liquids from saltwater – ,Pathosans, - ,video If you use cleaning chemicals in any significant quantity, you need to watch this video and check out this system. Just as your water softener uses salt to remove minerals from your drinking water, this system uses bulk salt and tap water to produce huge quantities of cleaning chemicals and sanitizing liquid on site. The process is simple but clever: electrical current is used to split the salt apart in salt water. Salt (sodium chloride) in water is split and filtered to become sodium water (Patho clean) and chloride water (Patho sans). Patho clean is good for scrubbing carpets, washing surfaces, etc while Patho sans kills germs wherever it goes. Agricultural companies use Pathosans units to sterilize live animal contact surfaces and hotel chains use it to produce cheap and effective cleaning products. The cost of the cleaner and sanitizer is around five cents per gallon. The machine itself commands a high price, but if your business buys its cleaner/sterilizer in 55 gallon drums, this system stands a good chance of saving you a lot of money. Industrial forklift crash prevention – sees around blind corners and runs on batteries – ,Collision Sentry This handy gadget runs on D batteries and uses magnets to stick to metal racking at blind 90 degree corners. When someone approaches from one side nothing happens, but when someone approaches from both sides simultaneously the device lights up a flashing warning to prevent a collision. Interesting ring knife for people who open a lot of packages – ,Handy Safety Knife This product is intended for people who use hand knives to open a lot of packages. It is inexpensive, disposable, and always to hand. There are plenty of places these would be unsuitable (any workplace with powered conveyors or equipment comes to mind), but the idea is so unique it deserves to be included for the one person who has the problem this tool answers. Two way radios for $15 instead of $300 – It turns out that two way radios have gotten a lot cheaper over the years, but just as a teenager can charge grandma money to fix her computer, so the contractors that most companies get their radios from are not in a hurry to tell everyone how easy the job has become. BaoFeng radios cost between $15 and $30, and do everything you expect from a walkie-talkie, but unlike what you’re probably using now, BaoFeng uses better equipment and lithium ion batteries standard. This translates into much longer run times and better performance. The ,simple $15 radio, and ,more complicated $30, radio can be found here, along with the ,cable, used to program them. This link ,here, discusses how to do it. Rust prevention in ,existing concrete structures, courtesy of NASA NASA has a lot of concrete structures near the coast, and saltwater corrosion is a problem for them. So they figured out a way to rust proof metal after it had been encased in concrete for years. If you have any concrete structure that’s showing its age, take a look at this link. Travel A handy power strip for world travel – ,Power donut A power strip that is tiny, travels easily, and adapts to different electrical systems around the world. Medical tools A skin magnifier to diagnose skin cancer - ,HUD A handy tool that uses your cell phone camera to take pictures of worrying moles. The results can be texted to a dermatologist for evaluation and a diagnosis remotely. Emergency blood stopping powder, a must have for first aid kits - ,Celox, and ,how to use This product is used to keep someone alive long enough for the ambulance to arrive in the event of severe bleeding. It forms a jell to stop blood flow at the injury and comes as powder packages, bandages, or a syringe full of the powder for gunshot wounds. Pioneered in the US military, this is one of several good haemostatic products that are must haves for any serious first aid kit. If you own a gun or a knife, does it really make sense to be totally unprepared for the results of gun and knife wounds? Emergency blood stopping pack – a second choice after Celox - ,QuikClot, and ,how to use QuickClot stops severe bleeding by absorbing the water out of blood, thus causing the clotting agents to become super concentrated at the injury site and stop the bleeding faster. As with Celox above, this will help keep someone alive long enough for the paramedics to arrive and save them. Liquid band aid – a cheap, generic must have for first aid kits – ,example link This is a generic product for minor to moderate injuries that sterilizes a cut and protects the injury site like a band aid. Good for use on tight locations that flex where band aids wouldn’t work. Because of its utility and tiny size it’s a good addition to any first aid kit. Betadine – inexpensive sanitizing solution for cuts used by EMT’s - ,Link In the old days parents used to use iodine or alcohol to clean and sterilize small cuts and scrapes (hydrogen peroxide will bubble dirt out of a wound, but it does not sterilize). Today we all have access to the same inexpensive product nurses and surgeons use; Betadine. It cleans and sterilizes wounds with much less burning than the old options, and most of us are familiar with it already as the brown skin staining wipe that doctors use before drawing blood. Transcranial Magnetic Stimulation or ,TMS, – a new treatment for depression, OCD, and ,Autism, – ,Related tech TMS is a revolutionary new tool that uses very strong magnetic fields to induce current flows near the surface of the brain. It’s essentially a big capacitor bank and a hand held coil employed for ten to twenty minute sessions to treat Depression and other mental conditions. Its painless, has virtually no side effects and is FDA cleared for a few conditions, but it’s in its infancy as a treatment. Promising studies have shown its potential to improve OCD, Autism and several other conditions. Ultrasound for your cell phone – production pending - ,Clarius For those trained to use it, Clarius is a new handheld ultrasound probe that allows diagnostic procedures to be done anywhere you have a cell phone. Production is slated to being in 2017. Athletic personal cooling gadget used by NFL and the military – pending shipping - ,RTX The RTX is intended for use by athletes or those working in very hot conditions; it’s essentially a plastic box filled with ice water you stick your hand into. What makes it effective is the small vacuum pump that puts a gentle suction on the hand, thus preventing the body from shutting off the supply of warm blood from the body’s core. This technology was pioneered by DARA and is now widely used on the NFL sidelines, but the huge price tag has thus far kept it out of the reach. The much cheaper RTX system expects to ship in 2017. Third world travel, missionary and prepper technology Clean burning hyper efficient ,cook stove, – ,see video The Aprovecho Research center designs and sells extremely efficient cook stoves for camping and long term use in the third world. These stoves have a core made from lightweight clay that reflects heat back into the fire box, allowing a few sticks and twigs to burn hot and clean with no smoke. The top of the stove is built to channel the hot gasses onto the cooking pot for maximum heat transfer with minimal fuel. To first world campers this translates into a neat (if heavy) stove that can burn almost any handy material to boil water and cook. For church groups and other organizations working in the third world these stoves are a way to ,drastically, reduce expenditures of time and money on fuel for cooking – ,see video,. For large orders, the stoves can be shipped in by cargo canister at prices as low as $5 a stove for the bare clay core that actually makes the unit work. Anyone that has to think about where their cooking fuel comes from could benefit from this technology. A light that runs on gravity like a grandfather clock – ,Gravity light Gravity light is a small generator that uses a sack full or rocks to produce electricity for simple indoor lighting. Just like a grandfather clock, as the weights descend their energy turns the mechanism, in this case turning a generator to drive the lights. While campers can use this product, it is intended for the third world where indoor lighting after dark means kids can learn to read and go to school. Anyone living without electricity could benefit from this product. One way to internet everywhere – ,Outernet, – ,See video Outernet is the best of the internet, broadcast one way only to earth from a satellite. The ‘Lighthouse’ model mounts to a standard direct TV dish and downloads many MB of data per day, while the ‘Lantern’ is a portable solar powered device that can travel anywhere and downloads at a slower rate. Both access the same information such as educational materials for students, warnings about local emergencies, weather forecasts, censorship free news, etc. Outernet devices slowly download this information and then allow users to log in and browse what is stored locally. The downside is that the data flow is one way only, but the upside is the system works as an end run around missing power and data infrastructure as well as censorship rules. Clean drinking water from any source - ,Lifestraw Access to safe drinking water is essential to health, and many of the worst diseases spread via contaminated water. The lifestraw family of products is invaluable to hikers and those working in the third world because it allows anyone to turn dirty water into clean safe water. The absence of safe water doesn’t just kill and sicken people, it drags down their finances, ensuring that those in crushing poverty stay there caring for the sick rather than using that time and money to send children to school. Freshwater from saltwater – the ,water cone,. A simple plastic cone that makes 1.5Lts of freshwater from saltwater. Water transportation from river to home – ,Water wheel In some areas of the world, even getting water to the home for cooking and bathing is a major job that pulls time away from education and other productive tasks. The water wheel cuts that time in half and improves quality of life. Kitchen Tools Portable drink carbonator – ,Bubble Cap A hand held drink carbonator that accepts standard CO2 bottles and standard soda bottles unlike the SodaStream. Parents corner $100 Life saving product to prevent SIDS in infants - ,Snuza Hero, - If you or someone you know has a child under a year old, this is the most important thing on this page. The Snuza Hero clips onto an infant’s diaper to monitor motion and breathing. If no movement or breathing is detected for 15 seconds the device vibrates to wake the baby, but if nothing is detected by 20 seconds it sets of a loud alarm. When SIDS kills a baby, all too often it happens in the middle of the night when both parents are asleep and it’s completely silent. Without some kind of alarm it’s almost impossible to intervene in time, so this can be the most important $100 spent on your baby. It saved our daughters life, and a quick read through the product reviews shows many more parents with similar saves. Free math and school tutoring - ,Khan academy, - ,promo video Khan Academy helps anyone at any level learn about math, science, and a variety of other school subjects using recorded lectures by skilled professors combined with interactive tests and automated tutoring. It’s hard to oversell this site; everything is free to use, nearly all subjects are covered, you can log in as a student, parent or teacher to monitor progress, and the site even has test prep for all the major tests like SAT and MCAT. The math section that started the site is particularly clever – when a student first logs in they take a ten question test that helps the program figure out their skill level, and then it suggests new math topics and tracks progress while periodically refreshing old topics as well. If you know anyone in school as a student, parent or teacher, tell them about this program. ,Odds are good they’ll thank you for it,. The drug talk – “,Licit and Illicit Drugs by consumer reports,” The do’s and don’ts of drugs are usually right up there with the ‘sex talk’ when it comes to uncomfortable conversations parents really need to get right, but often put off or miss altogether. Fortunately, consumer reports wrote an excellent book on the topic which is available for free online. The organization has a well earned reputation for impartiality, and it shows as the book talks about what each drug does, how it was discovered, and how it got to be legal or illegal. Having the facts makes smart choices possible, and this free resource is a must read for anyone over ten. $1.25 calculator wrist watch loved by grade school kids – ,Link Kids 5th grade and younger find these to be the height of fashion and prestige.

It’s a comic book format packed to the brim with useful tricks and tips delivered in an easy to read humor format. Kerbal Space Program - ,Link This game is a great way to build STEM interest in children and adults as you run a space agency for the ‘Kerbals’ and try to land on the moon or go to mars. All technology in the game also exists in the real world, rockets can be built from parts like Lego bricks and all the physics are as close to real as they can make them. Google ,Sky,, ,Moon, and ,Mars, + the ,100,000 stars, project and the ,scale of our solar system,. Bit of an astronomy dump here, but if you want to learn about our universe or teach your children, these are excellent resources. Google Sky, Moon and Mars let you explore these places in the same way Google earth explores the globe. The 100,000 stars project is an accurate, searchable 3D model of the nearest 100,000 stars to the earth, and the ‘scale of the solar system’ video shows how small we are by building a huge model in the desert. FanFiction.net This is a good way to encourage reading and incentivize writing practice. For any book, movie or TV show, there are fans who write stories about the canon, such as ‘what if she did this?’ or ‘what if this happened this way?’. These works of ‘fan fiction’ can read just like the original work, or can be very different with only characters from the original work. Everyone enjoys some kind of media, and ,FanFiction, is a good way to get them reading about something they already like. In many cases, the instant availability of interesting reading material on any internet capable device boosts reading skills and sets up a situation where writing is undertaken enthusiastically and for fun. We’ve all seen people type out angry rants when ‘someone is wrong on the internet’. Fan fiction sets up situations where the reader will find a story about characters they’re very invested in and say ‘This story is awful! I could write a better story that this!’. And they do. And the posted story gets comments about what the bran-new author needs to work on. And so they write some more to show them, show them all. After several months the same student who had to be forced to write a three page paper will be feverishly banging out ten page chapters twice a month to keep their fans happy. Chemistry article referencing the ,periodic table, and ,nuclear table How different ,engines work Anyone teaching STEM classes or with an interest in engines may find these animated diagrams useful. They’re not the most detailed, but they cover many different basic types of engines. ,This link, shows the standard four cylinder auto engine in more detail. Scan expensive text books or digitize your library – ,CZUR scanner CZUR is a $300 machine that connects to any computer and scans books into e-books. Scanners that automatically turn the pages cost more than a luxury car, so this unit is an inexpensive way to digitize pricey school textbooks, unusual books from your library, or just anything you want to read but don’t feel like lugging around in paperback. Speed is about one photo (which covers two pages of the open book) per two seconds, so a 300 page book will take about eight to ten minutes to scan. If your college still uses paper text books, consider spending the $300 once on the scanner, instead of two or three times a year at the bookstore. Bizarre wheels for projects, forklifts and robots – ,Mecanum Wheel Mecanum Wheels are wheels that allow a vehicle to slide sideways by counter-rotating its wheels. They’re used on forklifts that work in narrow aisles, and in other specialty applications. Anyone building a wheeled robot for a competition should be aware of these because of the performance edge they provide. Fun projects The ,Long Now, foundation building a ,clock, that will run for 10,000 years. The long now is a society dedicated to long term thinking, which involves several projects including a four story tall stainless steel clock that will run for 10,000 years, a project to record all human languages, and another to record old computer operating systems for backwards compatibility. Hundred year ,time capsule for a dollar A simple article on how to build a time capsule from a wine bottle that will last for one hundred years or more. This is a quick afternoon project that lets anyone from grade school kids to adults send a message to people decades or centuries in the future. Free satellite TV for $250 of ,equipment It turns out that free to air satellite TV is still around, and $250 worth of equipment will get you everything you need to watch it. This is a Ku band system (think direct TV sized) and mounts anywhere with a clear view of the southern sky. The programs are a mishmash of low budget shows and international content, but there are hundreds of channels, and they work anywhere you can see the sky. This package is understandably popular with members of the armed forces who want access to their own TV programming while stationed abroad. They also sell the old huge C band dish systems (8 ft across and larger) that still pick up content as well as direct downlink video received by news trucks. Programming varies wildly, but there are some reliable shows – Nebraska for example broadcasts their PBS stations down on C band. Telecom – ,how antennas work, + ,satellite coverage map, + ,how bandwidth works, + ,KU vs C band pro con Jumping shoes that give 6 ft of air – ,Kangaroo shoes Know as ‘acro stilts’, ‘power striders’ or ‘kangaroo shoes’, these toys allow for ,ridiculous jumps and let anyone run faster than the world’s fastest sprinter,. They use a composite spring very much like the flexible part of a compound bow and arrow to greatly increase the efficiency of running and jumping, and like skate boarders, are popular for the tricks skilled users do with them. Software defined radio – see and hear everything on every channel with this ,thumb stick We all know AM and FM radio from cars, and some know more types of radio like citizens band, ham radio, etc, but until recently, receiving on more than one channel required many different radios. Not anymore. ,Software defined radio, uses a computer to translate the signal, and this model costs $25, is the size of thumb drive, yet can receive anything from 500 Kh up to 1.7 Gh. In automotive terms, this would be like a car that could fly, drive, float on the water, dive under the water, rocket into space, yet it fit in your back pocket and cost $25. If you’ve ever thought about dabbling with radio, it’s never been cheaper or easier than this. A bee hive that ,dispenses honey through a tap, – no mess, simple and easy. Not something I ever thought about before seeing this, but smoking out bees and opening up a hive of angry stinging insects isn’t the easiest way to get honey, especially considering the resulting comb still has to be scraped and filtered. These guys figured out how to get bees to fill an artificial honeycomb with honey, and it can literally be emptied with a tap. Learn to knit… steel rings into medieval body armor – ,ringlord.com Anyone into the ,SCA, may find this old news, but some people still make armor and jewelry out of steel rings called chainmail. This site sells everything necessary to weave just about anything you want to make. Incredibly powerful magnets designed for particle accelerators – ,United Nuclear For all your incredibly powerful magnet needs. These magnets were intended for use in physics labs, and while prices range from $80 to $200, they are strong enough to amputate an arm if careful handling is not used. Magnetic wedding rings for magicians $25. Or use for cashiers to wipe credit cards – ,Super magnet man These magnetic rings look and feel like normal jewelry, but can be used in magic acts, or by cashiers to dish out vigilantly justice to abusive customers. While there are many potential applications, take care not to touch your wallet while wearing one. Multitool business card – about $1 per card to be remembered by clients/employers – ,Card, + ,Label, (Avery 5317) Business cards tend to lead short lives, but they don’t have to. The listed multitools are the size of business cards, yet they can perform a variety of useful functions, and with the addition of the linked label, they can become business cards. If you think it’s worth one dollar to have a client keep your card in their wallet for the next five years, consider some of these. Ultimate privacy monitor – no one can see your computer screen but you! – ,Hack how to This clever hack is useful for those who need a privacy monitor. Essentially, all monitors have a thin skin of polarizing plastic in the display to produce a useable image. If you take the monitor apart, peel off this layer and apply it to a set of glasses, only the person wearing the glasses can see the screen – everyone else just sees a blank white light. Home, construction and architecture Buy a $2000 cargo/shipping container for an indestructible backyard shed - ,Link Cargo canisters are ugly but very durable and less expensive than most methods of construction. Suitable for backyard sheds, or even as the basis for tiny homes and ,larger structures,, it can be useful to know this is an option. Color changing heat sensitive tile for showers – ,Moving color Most of us have seen that black plastic that changes color like a mood ring when held in a warm hand. It turns out someone made them into bathroom tiles that change from black to a rainbow of vibrant colors when the hot water comes on. In ,floor heating tubes, for very cheap winter solar heating (no solar cells needed) If you ever build your own home, remember this trick. Home heating is usually done with forced air through ducts, but this requires a very small area to be very hot (the firebox of the furnace). We all know burning gas and oil gets expensive, but most of the time it’s our only option; solar concentrators can heat water to 150 degrees F, or even 180, but they can’t approach the high temperatures needed for a forced air furnace firebox. However, if you cast plastic water tubing into the floor of the building when its being built, now you have a very larger area that only needs to be warm in order to heat the whole house. A ,solar hot water panel, made up of black copper pipe encased in vacuum tubes can be hooked directly to the system to heat your entire house for free even in the dead of winter. Hunting, ballistics and security related Z-Modo home ,camera system Trying to secure a home or business is never easy; almost by definition anything that gets broken/stolen happens when you aren’t looking. An eight camera system with DVR is a good fix for this, and Z-Modo makes many fine systems for around $200 to $300. Have you ever heard of a break-in that cost less than $300? Normally when you find out about a break in it’s far too late to intervene, and in most jurisdictions the police need three to six months to get the results back on a fingerprint search, and that’s assuming there are prints to find and the person leaving them already has a record with prints to search for. If someone gave you an assignment at your job would you still remember three months later? By contrast, an eight camera system deters some break ins, and if a break in does occur, it preserves video of everything that is taken, and everyone involved. The police normally have a pretty good feel for who is causing problems in a neighborhood, but can’t do much about it without clear evidence. With a camera system you can run the video back while you wait for the police to arrive, and then play them the video with everyone’s faces. Quite often the result is “Hey, I know that guy! Wait here while we go pay him a visit.” In this way a camera system can permanently remove bad actors from a neighborhood and help everyone sleep better. The slingshot channel. Yes, ,this is a thing,. If you want to see things hit by overpowered homemade slingshots built by an engineer/body builder and his wife, take a look. How to build a potato cannon for fun and ballistics demonstrations – ,spud gun, & ,Pumpkin chucking For everyone who ever wondered how to build an air cannon to throw potatoes, here is an expert. See also ,Pumpkin chucking, for similar designs. Pocket sized slingshot $20– ,Pocket shot A remarkably tiny slingshot that still throws for distance. Super compact Taser $300 - ,Pulse A recent shooting taser that is a nice mix of small size and functionality. Cheap disposable pepper cannon $40– ,Pepper blaster, - ,test video A tiny but highly effective way to deliver capsaicin to the face as cheaply as possible. While not a firearm, the device uses percussion caps to propel the pepper sludge, meaning it works at any temperature, in the rain in the wind, and doesn’t need to be charged up like a battery or a pressure can. Blackpowder derringer $180– yes ,they still make them An interesting tiny firearm that loads just as it did in the 1850s. World’s smallest full power bow $900– ,Liberty Bow, - ,test video This manufacture figured out that compound bows no longer need the heavy aluminum bar between the spring arms, so they removed it to create a bow with a 70lb draw weight that fits easily in a backpack. Pricy, but interesting. Computer tools Run a ‘who is’ search to find out who owns a website –eg, ,slanted news vs propaganda There are many sites on the web that purport to say something, but are owned by someone who has every reason to lie. A ‘who is’ search is a way to quickly find out who owns the website you’re reading. For example, if a web page claims solar panels cause cancer, a ‘who is’ search might reveal it to be owned by British Petroleum. Find old versions of software to roll back bad updates – ,Old version Sometimes it’s handy to be able to undo a bad software update, or re-install a program for the distant past; Old version allows you to do just that, simply and easily. Google ,Earth, and Google ,Maps, to navigate and explore our world These are known to almost everyone, but on the off chance someone hasn’t heard of Google maps, or its portable 3D parent Google Earth, take a look. Navigation and exploration has never been simpler. Aircraft and pilots Yes, you can ,fly small planes if you want to Aircraft are not solely the domain of the rich and famous. You can buy or build an aircraft for the price of a luxury car, and with a small propeller driven plane, your time is suddenly much more valuable. Draw a circle on a map with your home at the center and a radius of 8 hours driving. That’s about what most of us can do in a weekend; anything outside that circle is out of reach, or requires careful advanced planning. With an aircraft, that circle suddenly grows to 1000 or 2000 miles. Someone living in DC can hop into their plane after 5PM on a Friday and be relaxing on the beach in Florida before the sun sets. Cars and automotive The best motorcycle helmet ever – ,Scully AR-1 For those who ride, this is the dream helmet: continuous rear view camera, heads up display with GPS, turn by turn directions, integrated calls and music, you get the idea. Automotive ,DashCam, by ‘Boomyours” for $60 This strangely named camera of Russian manufacture is an indispensable tool for any car. When paired with a ,$5 micro SD card and adapter, (not included, must be purchased separately or it won’t run), the camera suction cups to the windshield like a GPS and records everything happening inside the car and visible through the front window. It starts up as soon as the car starts, records about a month of driving, and automatically overwrites the oldest videos so no action is required by the user, just plug it in and forget it. If you are hit by another driver, now you have video of the other person’s mistake and no amount of lawyers can change who is at fault. “It was my fault because I was on my phone? No, actually, the video clearly shows you hit me and I was not on my phone. That, and the GPS and G-force data shows where, when and how hard you hit my car.” In addition to crash uses, the camera also records what happens during a traffic stop, and many users find the police are more polite when they are being recorded. If not, well, you now have video of exactly what happened and YouTube is free. Finally, the micro-SD to SD card adaptor allows you to quickly pull the card after a hit and run, put the video onto the responding officer’s laptop, and show them exactly what happened within minutes of the accident, resulting in an APB and a much higher chance of catching the hit and run driver. BlueTooth OBD2 car ,diagnostic scanner for $7 This tool links to your Smartphone using the Torque app and allows you to read and reset trouble codes and check engine lights. It’s a cheap but invaluable tool, and great to have in any glove box. Convert your car to run on French fry grease – ,Golden Fuels For those interested in free fuel, Golden Fuels sells all the equipment needed to run your diesel truck on waste vegetable oil. The process is simple enough, mainly centered around filtering, and if you find yourself driving many miles in a diesel truck, using McDonalds as a fuel stop can be quite appealing. Does not exist, but badly needed Wrist watch multimeter It seems like anytime you want a multimeter, you don’t have one. Existing models remain the size of a sandwich, but if you look under the cover the electronics inside the huge case are tiny and all in one corner. In all the world, not a single electronics company will listen to their customers, ,even after it some grad students built one,, no one would produce it. I would pay a lot for this function in a wrist watch, but no one is willing to make one. Tax incentives for designing cars that are easier to repair Anyone who has ever repaired their own car knows how unnecessarily difficult they are to diagnose and repair. Engine bays are far too small, parts are designed for ease of manufacture, not ease of replacement, and the OBD2 system has all the speed and graphics of a DOS computer from 1985. Modern computers are capable of very advanced diagnostics, and repairability can be designed in, but at present there is no reason for any of the auto makers to do so. The poor and poorly educated in our economy seldom have the luxury of buying new cars. They, those most vulnerable to scams and most in danger of job loss and financial collapse due to automotive breakdowns are the group who get to maintain and repair our oldest and most worn out vehicles. Those better off can learn or pay someone to repair their cars, but those most affected by reparability are also the least prepared to cope. I would propose changing the tax structure for the auto companies – not raising or lowering taxes, just shifting the balance. If a company turns out cars that are easy to repair, they pay less tax. If a company makes cars that require unbolting the engine 6 hours of work just to change the spark plugs, they pay more taxes. The total tax income in a year doesn’t change, but each year a representative sample of vehicles are submitted to undergo common repairs, and the ones that make the mechanics wish for a flame thrower cost their parent company more in taxes. Socket bit screwdriver set – lost technology This was the best multitool screwdriver and socket driver I’ve ever seen, but it went out of production and it really shouldn’t have. I have no pictures of the device itself, so I’ll list out the features as seen in other similar products. First off it had a three inch long, square drive shaft with a spring loaded ball bearing on the end like this: Bitts stored in the handle like this ^, and three double ended socket drivers that rode on the shaft at all times size (16mm,-14mm), (13mm-12mm), and (10mm - bit driver) for the bits in the handle. The three sockets together let you press down on a socket and carried the force to the handle while the spring loaded ball on the tip kept the bits from falling off. To change bit size the user would slide off all three sockets, rearrange them to put the needed socket on the end and slide them all back onto the shaft. This one tool fit easily in any toolbox and did most of what a socket set does but without the heavy brief case full of sockets. Household sized ,VLM, for storing kitchen gear, shop tools and clutter.

When I apply makeup, it’s always cakey, flakey, and seems to slide off throughout the day. I have been using LA Girl as a foundation nowadays to cover up pigmentation. How do I stop this problem?

This is long but I hope you find it helpful. I can’t really speak impartially but I think it’s worth reading. Why this happens and what to do about it depend upon a few factors: -What kind of surface are you applying your makeup TO? You need a smooth surface. Your face should be clean, with a moisturizer appropriate for your skin-type applied followed by a Foundation primer once the moisturizer is fully absorbed. You should exfoliate Gently as needed- and ONLY as needed. This is doubly true if oiliness or acne are an issue for you. Excessive or overly harsh exfoliation will damage the surface of the skin(causing a rough surface) and it will cause overproduction of oil, which is counterproductive if your skin is oily to begin with. If your makeup starts sliding off after a few hours, then you might look for a mattifying moisturizer & primer. Don’t overdo it with either one. Carry blotting sheets with you. These will absorb excess oil without destroying your makeup. -What KIND of makeup are you using & is it right for your skin? Not the brand but the formulation: liquid, cream, powder/mineral, etc. Some types of foundation are better than others for some skin types. If your skin is dry, for instance, a powder foundation is going to make dry skin look worse and amplify any fine, dry lines or flaky surface skin. Liquid foundations are generally pretty good for most people provided that it’s appropriate for your skin type (moisturizing, oil-free/mattifying, etc.) and applied to properly prepared skin. But, by the same token, don’t assume that a foundation type is wrong for your skin because it sounds like it should be. For instance, if you have oily skin, you might think that “cream” foundation is wrong for you but that isn’t automatically the case. Whether they’re brides, models, TV anchors or movie stars, pro MUA’s use cream foundations on their clients more often than not. These are often oil free or contain very little. Some even have a silicone base. And- while the containers are very small(an advantage for a MUA’s kit which may need to contain shades for any &every skin-tone) these products are HIGHLY pigmented so a little goes a long way. The coverage Is buildable making the product versatile; depending on how you apply, you can get a sheer look all the way up to full coverage- all from the same tiny pot of product. Look for brands like CinemaSecrets, BenNye & JoeBlasco. They aren’t “Cheap” as such (especially CS or JB) but if you consider that one tiny pot of pro-formula cream foundation can contain as much pigment as five or ten bottles of drugstore liquid foundation they aren’t really that bad. Whether it’s 3.50 wet&wild(not knocking it-Good old W&W has some Incredibly good products with amazing pigmentation for SUPER cheap!) or $18+ L’Oréal- that ounce or two of Liquid foundation is mostly water & Fillers with as little as 2% pigment. You’d think that prestige brands like MAC, Smashbox or Nars are better than drugstore brands or that they ARE the pro-Brands but this isn’t always the case; this is especially true of liquid foundation. You mentioned LA Girl- this brand is VERY reasonably priced and they make some pretty good products- some of which are carried by suppliers (like Camera-Ready Cosmetics) that cater to Pros, so you KNOW they’re good! CRC carries (or at any rate they DID) LA Girl’s Pro.Conceal HD concealer, for instance. So does Amazon & it’s a little cheaper there; I bought the almost-full set of shades (sans color correctors) for what worked out to be about $2/tube. Amazon & its fast, free shipping may be cheaper but CRC is a small-business founded by a very nice professional MUA named Mary who’s success is proof to me that life isn’t always cruel& unfailr. Jeff Bezos, on the other hand, is a Volcano-Lair & a Persian cat away from being a Bond Villain! Some of us don’t have the option of not pinching pennies but If you do- PLEASE buy from CRC. I don’t work there, I just really like the company & used to be on a stylist/ MUA board with Mary. That concealer is a really good, versatile product for an AMAZING price. It’s highly pigmented without being greasy with a nice finish- not too dewy or too matte and it can do double duty as a foundation as well. It’s just occurred to me that this might actually be the product that you’re using & not liking. Like the cream makeup, you can vary the coverage by “sheering it out” with moisturizer. You could put a dab IN the product but I like to put it over the moisturizer before it’s all the way soaked-in The tubes come with a brush applicator but you can pull that out or leave it & just squeeze a glob onto your hand. -How are you applying the product and are you blending it properly? More isn’t always better. With liquid foundations, I like to start By dabbing it in the center of the face, making sure to put a bit on the under-eyes & corners of the the nose. With my hands, I spread outwards toward the ears, jaw& hairline, then blend with a sponge or brush onto the neck, ears & hairline until all you can see is nice skin. If there are missed-spots or something needs more coverage, dot a bit on that place, Then work outward as above. It’s a Common mistake to apply the product WITH a sponge. It eats the product- It’s a sponge. It absorbs-that’s what it’s SUPPOSED to do. Cosmetic companies LOVE this because the faster you run Out, the sooner you need to buy more. Sponges also contribute to over-application by keeping you from being able to see & feel how much product you’re putting on your face Vs. How much you’re feeding your sponge. Much of this is also true of brushes- they’re pretty good for putting foundation on your face but they do waste product, especially if you’re putting the brush IN the product and “loading” it as if it’s paint (both the residual product AND the “loading” hasten the deterioration of your brushes) AND they aren’t great for distributing the product plus- BRUSHSTROKES. Foundation may not BE paint but there are some similarities when it comes to applying it. Put foundation on your hand, then use a brush to apply to the face & blend out w/ fingers then a sponge. For moving cream&liquid products around, a silicone “sponge” is great! (I got mine in a set of three It’s not really a “sponge” at all. They’re actually fairly similar in material and construction to the silicone bra-inserts colloquially referred to “chicken cutlets”. They’re made of Silicone gel sealed inside a silicone-film skin. The makeup sponges are of a much firmer silicone. They’re flexible but not squishy & floppy like the silicone bra pads which feel pretty similar to boobs. They aren’t good for blending or smoothing but they don’t absorb product AT ALL and very little sticks to it, making them great for applying foundation to the face& moving it outward. -Are you setting your makeup & how? The traditional makeup setting method is to use powder. It’s not a bad method & most of the time, it works. But for some situations&skin-types, powder isn’t good. If it’s hot out, for instance, you’ll probably sweat under it which can cause a “cakey” look. Also, when it’s warm and sunny , heavy matte makeup looks strange. When it’s warm, you want fresh, Dewy & natural. If your face gets a bit shiny, a dab of powder can fix it but if you’re very oily and try to beat it back by powdering every time you get shiny, you’re just going to end up with a greasy, cakey mess that will settle into expression lines even if you’re young (This is actually a rudimentary form of “old age” Makeup) which may or may not stay on your face. If you’re oily, an initial application of powder can work & maybe a second touch-up but blotting tissues (the ones without powder) are your best bet. I like the blue ones Clean&Clear makes but Walgreens’ generic version works just as well and they’re usually a buck or two cheaper. The plain paper blotting tissues, made of a thin, slightly glossy paper that gets transparent as it soaks up oil are another option. They’re biodegradable- unlike the blue polymer-film blotting sheets, equally (or very nearly as) effective. They’re also usually (but not always- Looking at you, MaryKay!) much cheaper- probably because this is more or less the EXACT same paper from which toilet-seat covers are made. By the transitive property of paper degradation, Blotting papers are ALSO(probably)flushable. If you’re ever in a situation where your face- foundation or no- is shiny & greasy and you don’t have a way to fix it, just use a seat cover- don’t wad it up, press it flat against your face and press like you would with a blotting sheet. OK, so MAYBE it’s not the most dignified thing in the world but hey, which is worse. If powder isn’t a good option for whatever reason, or if you need your makeup to really last- use a setting spray! There are several. Ben Nye’s is the cheapest I’ve come across. It’s chiefly intended for theatre & dance performances; BenNye is one of the most well known stage makeup brands. it’s not exactly what you’d call luxurious- it smells a bit like mouthwash- but it IS effective and has an antiperspirant. I have it and I use it for times when I’ll be dancing but doing significant makeup. Urban decay makes a setting spray as well, most brands from pro & prestige brands on down, make one but the one that seems to be the Most popular are the “marbles”: they come in “Blue” & “green”. I think that green may be alcohol based and waterproof but I can’t remeber right off hand. Another thing to try is a “facial mist”; it’s not a fixative as such but it can set your makeup. I like the Mario Badescu rosewater facial mist. It’s not TOO nexpensive but there are cheaper options- including making your own. - Are your expectations realistic? Makeup- even the heaviest, most highly-pigmented stuff- has It’s limits. It’s for covering discoloration & Evening skin-tone. It can’t do anything about texture. Deep acne scars, large, open pores or severe, widespread acne that can be covered with makeup but it won’t disappear. The dry, scaly,”lunar-surface” effect that you sometimes see on makeup applied over acne is often due to the surface of the skin being dry from harsh scrubbing & products. The real bitch of it is that both the products meant to treat acne and the makeup That a lot of girls to hide it can make it much worse. -Do you know your skin type; are you using the right products & taking good care of your skin? Good skincare is important but good products don’t need to be. Some of the best are actually quite reasonable. Cetaphil cleanser for example is used & recommended by dermatologists & very reasonably priced. It comes in two formulations: normal-dry(a thin, lotion that doesn’t require rinsing) & normal to oily(a foaming cleanser which does); every big chain drugstore & big-box store makes a generic(at least of the lotion-type) and they all work the same. Cetaphil also makes a good, simple moisturizer. I like Clinique’s Dramatically Different moisturizing gel for normal to oily skin. It’s not cheap at all but the HUGE bottle lasts a LONG TIME. Jojoba(Ho-Ho-Buh) oil is amazing stuff. It is nearly identical to the sebum produced by your skin. It’s relatively cheap, widely available and good for basically any skin-type; it is VERY helpful for acne, actually. If you have oily skin that doesn’t break out, it won’t help you but it won’t hurt either. You can use it all over your body, in homemade scrubs, even in your hair in very small amounts at the ends. For your situation- pigmentation issues and your makeup slides off during the day, I think that you should try using a concentrated cream foundation. CRC has SO many- even the type that Make sure that your skin in clean, moisturized & smooth. Wear a good moisturizer & primer & make sure that you’re applying the foundation correctly. Concentrated cream foundations are great but you not only don’t need much, too much will look bad. There’s a trick to applying. Scoop out a TEENY amount with a makeup spatula and put it on the back of your hand to warm up a bit & then dot it on your face,(Use a silicone sponge) starting in the center of the face & any places That might need concealing like the under-eyes & sides of the nose where it meets the face& proceed as above. CRC offers samples of many (most, even?) of their offerings.. Pretty much anything that CAN be scooped, poured or pumped- out into a little sample container will be for a nominal fee. Obviously a sample of say, eyeliner pencil, powder blush/eyeshadow or False lashes isn’t feasible but You can order samples of all of the different foundations, primers, too, I think. They should be good for At least one application. Their customer service is good; they should be able to advise you much better than I could.

What are the best ways to think of invention ideas?

Cheat Sheet for Innovators I’ve been an inventor for fifty years. I have many patents and have spent much of my life in R&D departments. My patents involve software, electronics, and mechanical devices. I have a cheat sheet that I refer to when I need ideas. Note that this is more of a train-of-thought than an outline.

Get those gears turning… 24) ,Leverage Your Own Talent a) Are you a good writer? Start an online business for writing resumes, composing advertising copy, or proofreading/editing/polishing for authors. b) Are you good with people and have some nice dress outfits? Become a sometimes local­ rep for companies that occasionally need local representation. c) Do you have experience and credentials in some specialty? Become a consultant by first writing a series of blogs and building your profile, then create an online presence that you can market. d) Do you have some creations that you are especially proud of, be they sculptures, woodcrafts, ceramics, or clothing? Don’t sell them but, instead, use them as a portfolio to advertise for custom work, as people often have very unique needs yet cannot find a qualified provider – and they are willing to pay for it. e) Maniac Mechanical Computer (Kit - fairly sophisticated) - Mechanical computer to be assembled. Probably plastic parts but maybe laser-cut wood. Base plates lock together as a back-plane – connected via address/data/control bus: probably 16-bit rotational but maybe multi-lever binary buses. 6x2 text display (5x7 font) for output, 20-key mechanical pad for input. (i.e. 0…F, Enter, Fn, BS, Esc) 25) ,Curmudgeon App/Website a) There are plenty of social sites such as Facebook and Twitter for sharing your day­-to­day experiences. But many people prefer to rant and have trouble finding victims to listen to them because people may not agree with them and are sick of listening to them. b) It would be great if a website/app allowed people with like minds to congregate, yet allowed those who disagreed to intervene as well. The rants could be relentless so the app would have to be able to make efficient use of screen real estate and direct the user’s eyes based on his/her interest and key factors. c) Ideally it would parse the ranter’s text to identify his/her topic and stance and then be able to route him/her automatically. d) Rants that were heavily liked or disliked ought to be saved and then automatically injected into future conversations as blasts from the past. e) It would be nice if it could chart public opinion versus rants as well. 26) ,Soda Vend Mechanism a) It’s apparent from the plethora of mechanisms in soda vending machines that nobody has yet discovered the way these machines ought to work. b) A good solution will be reliable, low­-cost, have few moving parts, will not shake or break the bottles, accommodate all bottle/can size and shape variations, and be easy to load. Simple objectives – dreadful solutions. c) On the web, research the ways these machines operate, learn about common problems with them, get familiar with the patents related to their mechanisms, and try to think of a better way. For instance, if there are five rows of ten racks each then there should be no more than fifteen possible slides or pivots; ideally even fewer. 27) ,Mobile Phone User Interface Improvements a) What are the most annoying aspects of the user interface on a mobile phone? b) Does it bother people that they often are unsure of whether their tap was hard enough so they tap again only to have it go past the expected page? c) What about buttons and links that pop up just as the user taps, causing a different action that what was intended? d) And going back is often a problem when a user is deeply nested into pages, because they either have to wait for each to load or end up going too far back. e) What about images that are too small to see yet that won’t zoom when you pinch outward? f) There are many such issues on all type of smart phones and tablets. g) Would you expect to be able to amend these situations with an app or would you sell your solutions to the handset manufacturer? 28) ,Outdoor Décor a) Home improvement stores do a huge business and you could be wealthy if you invented even one product that they wanted to carry. Look around in your house or go outside and look around. b) See those ugly white risers that support the hedge sprinklers? Why can’t you buy an inexpensive breakaway sleeve to drop over the risers that was green and leafy and blended in with the bushes? c) Fingerprints and gunk all over the window in the storm door? You ought to be able to buy static-­stick patches to protect those areas, maybe with floral prints or sports team logos. d) Scratches and flaking paint on the window and door frames? The paint for those can be found but if you found a small bronze, white, or aluminum metal touch-­up kit right next to the checkout, you’d buy it in a heartbeat. e) Concrete chips and potholes? You don’t want to buy a big can of concrete adhesive and hefty bag of concrete. It’s too bad you can’t buy a really good kit for fixing small areas. f) Dry rot on your eaves? You need a strip of white L-­shaped plastic to cover it, but the ones you can find have inner gussets or staggered holes. 29) ,Scan via Mobile Camera a) Most people have a lot of items they want to scan, categorize, and often do character recognition on: records, checks, collectibles, business cards, and all of their old photos. b) There is a popular scanner that comes with software for this very purpose. The problem is that scanning is a slow operation and most people now use mobile devices and don’t want to carry their scanner around with them. c) It would be great if there were an application that would work similarly, ran in the background so you needn’t wait for it, and that would ingest images from the mobile device’s camera rather than a scanner. d) Large images could be snapped in multiple pieces and the app would stitch them together before processing them. e) What are you waiting for? Start coding! 30) ,Leverage Disruptive Changes a) Adoption of smart phones means women will need their purses less. How might this disruptive change be taken advantage of? b) A "makeup mirror" phone app, uses the front camera, horizontally flips the image? c) A flat/sturdy pocket ­size makeup kit? d) Key chain makeup dongle? e) Disposable high ­quality makeup in vending machines? f) Skype plug-­in for makeup photo­-enhancement? 31) ,Novelty Items a) Try to come up with clever novelty products such as an adapter that allows a beer tapper handle to be attached to a flush valve for use on urinals and toilets in bars and clubs. b) How about a cat litter box that prevents cats from tracking the litter particles all over the room. 32) Easy Mobile Apps a) DealFinder ­ Monitors your e-­receipts and amazon purchases for items you buy often and then searches for deals on them when it is about time to buy more. b) Toxic Sewage ­ Interactive video game that involves gross acts, similar to those on fear factor but even crazier. It allows you to select an avatar/player/victim such as a politician, actress, or even a friend from your photos. c) Custom Group ­ A brandable/customizable app to be used for a bowling league, HOA, boy scout troop, small company, or church.

What are some e-commerce sites selling cool technology gadgets?

UPDATE: This is a long answer, and it’s been collapsed once for lack of attribution. There is no way to attribute the findings contained herein, as they are all my own. What you see here is my personal list of interesting inventions and technologies. Some of them I found through my work, others I found in the technology and new-gadget press over the years. Some, in fact, my wife bought for me. All of these are items I have either personally tried, had experience with or read about on the same pages I link to for each item, and I receive no compensation, perks or attention for having compiled them. As Malcolm Gladwell described in his book ‘,The Tipping Point,,’ there is a type of person, whom Gladwell calls a ‘maven,’ who collects information and from whom others get said information. I have been informed that I fit this description. This is not an inappropriate attempt at viral advertising, nor is it unattributed research. This is just a Gladwellian maven, industrial engineer and safety manager doing what we do, and my only hope in posting it was that other people, who are or may later face problems these technologies have helped me solve over the years, may also be helped by them. I earn nothing but perhaps an upvote for this, that and the satisfaction that my amusing little gadget-list may help, or at least amuse, my fellow humans. After all, I’m an engineer. Collecting gadgets is one of our favorite activities. The Toolbox The best multimeter ever – ,Mooshimeter Most multimeters are the size of wallet or a book, and can only display information in a string of digits. You must be within a foot or two of what you want to measure, have three hands, and the meter can’t save the information it displays any better than binoculars can. The Mooshimeter changes all that. It’s a bit smaller than a normal meter, runs for six months on two AA batteries and connects wirelessly to your cell phone. This means you can tuck it under the hood of your car and monitor that finicky electrical hiccup while driving down the highway at eighty miles per hour. It also records up to six months of data, so you could record voltage and current (yes, both at once) on a given circuit breaker to compare spring vs summer AC usage at home. The auto ranging display also makes diagnostics much simpler by showing complicated information in a simple graphical format. Take a look at the link above to see all the details. Armored heat seeing cellphone – ,Cat S60 -This phone is does everything you expect a good Android phone to do, and so much more. If the Nexus series phones were a team of trendy sedans, the S60 would be a mad max armored truck. It can survive a six foot drop onto concrete and a one hour swim in the 16ft deep end of the pool. This thing can literally see in the dark; not night vision or by amplified star light, no, it see’s the heat emitted by everything around it. Animals in the dark, overheated machinery in a factory, hot water pipes hidden behind a wall, they literally glow in the S60s thermal camera. If you work with your hands it doesn’t take long to find uses for this technology. Handyman? See drafts and missing insulation through walls, trace water pipes, check for overheated circuits in a breaker box and find out where that infernal drip of cold water is coming from. Police officer? See which cars have been driven recently by their glow and track suspects in total darkness by body heat and the hand prints they leave whenever they touch something. Parent? Find your daughters pet when they get lost in the woods or hide in the crawlspace. Take your sons temperature when he’s sick or help him get the oven temperature right to bake cookies. GammaPix is a free ap for Apple and Android phones that uses the CCD camera in the pone as a crude geiger counter to detect nuclear radiation. It takes about 60 seconds to get a reading, but if you have a phone, you now also have a radiation meter. Seriously, who ,doesn’t, want this? Steel wire banding tool strong enough to clamp a hydraulic hose on – ,Clamp tight Clamp tight is like having hundreds of high quality stainless steel hose clamps, zip ties, and fasteners of every time, yet still it still fits in your toolbox. This thing was developed for use on ocean sailing boats as there tend to be very few hardware stores floating out at sea, and boats break down like everything else. To use it, you wrap the wire around the piece to be secured, then around the tool. Turning the bolt pulls the slack out of the wire then rotating the tool locks the wire down like a giant copy of the wire tie that holds a bread bag closed. It does have one obvious weaknesses – you have to have enough clearance to rotate the tool, so some automotive repairs are out of the question because there just isn’t enough room. Overall though, it would be tough to find a more compact and lighter way to repair so many different breakdowns. Nice self-contained butane soldering iron the size of a highlighter – ,Weller, $50 I can’t vouch for this one personally, but a small reliable iron that heats up in seconds and can be used on no notice anywhere it’s needed is a huge help. How often have you needed an iron, but not had a ready plug and stand for it where you were working under the dashboard of the car? 1800 Lumen, rechargeable flashlight by ,Nitecore ,$55 Growing up, ‘flashlight’ was a word that meant ‘that big heavy plastic thing we keep in the kitchen drawer that glows a dim yellow and always has dead batteries when we need it’. No more. Nitecore makes a variety of good lights, but this is the one I keep clipped to the lip of my pocket. Because I work with my hands, I like to be able to see what I’m working on, and ,very, few things break down in the middle of a well lit work bench in the garage. When something needs attention, it always seems to be at night, up underneath a dashboard, deep in a computer cabinet, or some similar difficult to see location. Since I got this light I’ve never had trouble seeing what I’m doing. It has the usual high/medium/low settings with some flashing options for emergency use, and when I need everything it can do, 1800 lumens is as bright as four car headlights. The battery usually goes a month or two between charges, and any 18650 charger can recharge it in a few hours. $300 CNC Laser cutter/etcher ,tool These $300 laser cutters have become available recently on Ebay, and they offer remarkable utility at a very reasonable price. Various ,reviews, are available; the user interface takes some getting used to, and the mirrors often need alignment after being shipped in from overseas, but after that the cutter will cut and etch words, pictures and just about anything else onto an area the size of printer paper (about 8 by 12 inches). The cutter can be used to make puzzles, pet tags, precision cut wood and plastic, etch metal and glass, etc. A very helpful maker tool. There’s even ,an upgraded controller, for those who want it. Paper thin microscope lens that sticks to your cell phone - ,Blips The link says it all – this thin slip of plastic the size of a post-it note will turn your cell phone camera into a microscope. Useful for outdoor adventurers, detectives, teachers and anyone else interested in the world around them. $6.50 tiny pocket telescope you can carry everywhere - ,DX This inexpensive tool weighs next to nothing and is tiny enough to fit in anywhere. Good for tracing wiring in a high ceiling, aircraft or bird watching, hiking, playing spy with the kids, etc. Pipe style building materials that use electrical conduit at $3.50 per 10ft section – ,Maker Pipe There are many build systems that can be used to build anything, but most of them like ,80/20, cost a fortune (think $15 per ft!). Maker pipe uses simple, inexpensive clamps plus cheap 3/4inch electrical conduit to build nearly anything you could imagine. If you need to build anything from carts to furniture to equipment, give this one a look. Must have Chemical identification – ,WISER web site, and ,WISER app, download WISER is a chemical identification book long carried by firefighters who need to quickly find out: “what’s in that burning tanker truck, and what will it do to us?” The book used to cost less than $20, but today the entire program is available for free download as the WISER app. If you ever find yourself facing a mystery chemical spill, do you want to be one of the clueless people wondering what to do, or do you want to be the person who looks up the chemical in the first thirty seconds and tells everyone what it is and what you have to do next? The app is free and will happily wait on your cell phone until you need it; don’t be clueless, be WISER. Industrial and special purpose tools Laser paint scraper and cleaning tool – ,P Laser, and in action ,video An interesting scraping process similar to sand blasting, CO2 blasting and bead blasting. I can’t vouch for this product, but I’ve never seen anything else like it either (as of 2016). MAD ,speakers for extreme distance, volume and clarity Planar speakers, like the ones above are very different from standard paper cone speakers. If normal cone speakers are like light bulbs spreading out in all directions, planar speakers are like lasers. Where cone speakers fade out over distance and interfere with each other, planar speakers can be heard at ridiculous distances, and over other noises. Probably their neatest trick is that in a noisy 90 dB environment, this speaker can clearly be heard an understood even at 80 dB. EBS 260 ,Handheld printer, - - - ,Video This is a handheld printer that allows you to print just about anything on just about anything else. It only does one color at a time, but its remarkably fast and simple to use, especially for complex data that needs to be flawlessly loaded from an inventory control system. On site, eco-friendly cleaning and sanitizing liquids from saltwater – ,Pathosans, - ,video - If you use cleaning chemicals in any significant quantity, you need to watch this video and check out this system. Just as your water softener uses salt to remove minerals from your drinking water, this system uses bulk salt and tap water to produce huge quantities of cleaning chemicals and sanitizing liquid on site. The process is simple but clever: electrical current is used to split the salt apart in salt water. Salt (sodium chloride) in water is split and filtered to become sodium water (Patho clean) and chloride water (Patho sans). Patho clean is good for scrubbing carpets, washing surfaces, etc while Patho sans kills germs wherever it goes. Agricultural companies use Pathosans units to sterilize live animal contact surfaces and hotel chains use it to produce cheap and effective cleaning products. The cost of the cleaner and sanitizer is around five cents per gallon. The machine itself commands a high price, but if your business buys its cleaner/sterilizer in 55 gallon drums, this system stands a good chance of saving you a lot of money. Wave glider,, an ocean drone that can cross oceans and is powered by wave action These inventors figured out that while waves make the surface of the water go up and down, they have zero effect on the deeper water. The torpedo shaped bottom has fins that ratchet it forward every time it’s hauled up and down by the surface drone bobbing on the waves above. They work in very small waves and category 5 hurricanes equally well and so can be used to take readings, monitor for science/defense, or conceivably to transport illicit cargo from one continent to another. Industrial forklift crash prevention – sees around blind corners and runs on batteries – ,Collision Sentry This handy gadget runs on D batteries and uses magnets to stick to metal racking at blind 90 degree corners. When someone approaches from one side nothing happens, but when someone approaches from both sides simultaneously the device lights up a flashing warning to prevent a collision. Interesting ring knife for people who open a lot of packages – ,Handy Safety Knife This product is intended for people who use hand knives to open a lot of packages. It is inexpensive, disposable, and always to hand. There are plenty of places these would be unsuitable (any workplace with powered conveyors or equipment comes to mind), but the idea is so unique it deserves to be included for the one person who has the problem this tool answers. Two way radios for $15 instead of $300, – It turns out that two way radios have gotten a lot cheaper over the years, but just as a teenager can charge grandma money to fix her computer, so the contractors that most companies get their radios from are not in a hurry to tell everyone how easy the job has become. BaoFeng radios cost between $15 and $30, and do everything you expect from a walkie-talkie, but unlike what you’re probably using now, BaoFeng uses better equipment and lithium ion batteries standard. This translates into much longer run times and better performance. The ,simple $15 radio, and ,more complicated $30,radio can be found here, along with the ,cable, used to program them. This link ,here, discusses how to do it. Rust prevention in ,existing concrete structures, courtesy of NASA NASA has a lot of concrete structures near the coast, and saltwater corrosion is a problem for them. So they figured out a way to rust proof metal after it had been encased in concrete for years. If you have any concrete structure that’s showing its age, take a look at this link. The ,Bad AXX, – an improved ax for fire fighters - $250 to $300 This is a Swiss army knife for firefighting: it’s a step up to high windows, it’s a repelling anchor point to get you off the roof when it’s on fire and collapsing, its wrench to shut off gas lines and open fire hydrants, it holds you’re forced entry tool, and the head cuts without ever getting stuck. It’s real and in production – ,check out the video,. Travel A handy power strip for world travel – ,Power donut A power strip that is tiny, travels easily, and adapts to different electrical systems around the world. Medical tools - ,Link to more medical tools Emergency blood stopping powder, a must have for first aid kits - ,Celox, and ,how to use This product is used to keep someone alive long enough for the ambulance to arrive in the event of severe bleeding. It ,forms a jell, to stop blood flow at the injury and comes as powder packages, bandages, or a syringe full of the powder for gunshot wounds. Pioneered in the US military, this is one of several good haemostatic products that are must haves for any serious first aid kit. If you own a gun or a knife, does it really make sense to be totally unprepared for the results of gun and knife wounds? Emergency blood stopping pack – a second choice after Celox - ,QuikClot, and ,how to use QuickClot stops severe bleeding by absorbing the water out of blood, thus causing the clotting agents to become super concentrated at the injury site and stop the bleeding faster. As with Celox above, this will help keep someone alive long enough for the paramedics to arrive and save them. Liquid band aid – a cheap, generic must have for first aid kits – ,example link This is a generic product for minor to moderate injuries that sterilizes a cut and protects the injury site like a band aid. Good for use on tight locations that flex where band aids wouldn’t work. Because of its utility and tiny size it’s a good addition to any first aid kit. Betadine – inexpensive sanitizing solution for cuts used by EMT’s - ,Link In the old days parents used to use iodine or alcohol to clean and sterilize small cuts and scrapes (hydrogen peroxide will bubble dirt out of a wound, but it does not sterilize). Today we all have access to the same inexpensive product nurses and surgeons use; Betadine. It cleans and sterilizes wounds with much less burning than the old options, and most of us are familiar with it already as the brown skin staining wipe that doctors use before drawing blood. Transcranial Magnetic Stimulation or ,TMS, – a new treatment for depression, OCD, and ,Autism, – ,Related tech TMS is a revolutionary new tool that uses very strong magnetic fields to induce current flows near the surface of the brain. It’s essentially a big capacitor bank and a hand held coil employed for ten to twenty minute sessions to treat Depression and other mental conditions. Its painless, has virtually no side effects and is FDA cleared for a few conditions, but it’s in its infancy as a treatment. Promising studies have shown its potential to improve OCD, Autism and several other conditions. 3D4Medical, – awesome free to $50 anatomy app Amazing anatomy software good enough to train doctors but simple enough for consumers to use. ,Incredibly complex 3D anatomical models, that can be sliced, searched and moved to understand how our bodies should work and how they can fail. When you talk to an auto mechanic, the smart consumer brings the manual along to show what’s wrong. Is your body less important than your car? Ultrasound for your cell phone – $2000 ,Butterfly IQ The consensus among many physicians is that ultrasound is becoming the new stethoscope (examples and ,ultrasound how to videos,). It can do all the same tasks, but much better, as well as catching a lot of other conditions. The new Butterfly IQ ultrasound scanner dumps the old piezoelectric emitter for a new chip that can do the job of all external probes, has on board signal processing, runs for 2 hours and links to your smartphone. You wouldn’t wear a blindfold to clinic because you’re such a great doctor that you don’t need your eyes: why leave ultrasound imaging in radiology when you can tuck it into your pocket and improve your patient outcomes? Tech off the grid Clean burning hyper efficient ,cook stove, – ,see video The Aprovecho Research center and ,Envirofit, designs and sells extremely efficient cook stoves for camping and long term use in the third world. These stoves have a core made from lightweight clay that reflects heat back into the fire box, allowing a few sticks and twigs to burn hot and clean with no smoke. The top of the stove is built to channel the hot gasses onto the cooking pot for maximum heat transfer with minimal fuel. To first world campers this translates into a neat (if heavy) stove that can burn almost any handy material to boil water and cook. For church groups and other organizations working in the third world these stoves are a way to ,drastically, reduce expenditures of time and money on fuel for cooking – ,see video,. For large orders, the stoves can be shipped in by cargo canister at prices as low as $5 a stove for the bare clay core that actually makes the unit work. Anyone that has to think about where their cooking fuel comes from could benefit from this technology. A light that runs on gravity like a grandfather clock – ,Gravity light Gravity light is a small generator that uses a sack full or rocks to produce electricity for simple indoor lighting. Just like a grandfather clock, as the weights descend their energy turns the mechanism, in this case turning a generator to drive the lights. While campers can use this product, it is intended for the third world where indoor lighting after dark means kids can learn to read and go to school. Anyone living without electricity could benefit from this product. Clean drinking water from any source - ,Lifestraw Access to safe drinking water is essential to health, and many of the worst diseases spread via contaminated water. The lifestraw family of products is invaluable to hikers and those working in the third world because it allows anyone to turn dirty water into clean safe water. The absence of safe water doesn’t just kill and sicken people, it drags down their finances, ensuring that those in crushing poverty stay there caring for the sick rather than using that time and money to send children to school. Freshwater from saltwater – the ,water cone,. A simple plastic cone that makes 1.5Lts of freshwater from saltwater. Water transportation from river to home – ,Water wheel In some areas of the world, even getting water to the home for cooking and bathing is a major job that pulls time away from education and other productive tasks. The water wheel cuts that time in half and improves quality of life. Fold-a-scope The one dollar paper microscope that fits in your pocket and is ,good enough for lab tests,. The Paperfuge A centrifuge that works anywhere without power and achieves 125,000 RPMs. Under development for malaria testing. ,Development documents on how to build one,. Also, here’ s a video interview with the inventor explaining them: Kitchen Tools Portable drink carbonator – ,Bubble Cap A hand held drink carbonator that accepts standard CO2 bottles and standard soda bottles unlike the SodaStream. Parents corner $100 Life saving product to prevent SIDS in infants - ,Snuza Hero, - If you or someone you know has a child under a year old, this is the most important thing on this page. The Snuza Hero clips onto an infant’s diaper to monitor motion and breathing. If no movement or breathing is detected for 15 seconds the device vibrates to wake the baby, but if nothing is detected by 20 seconds it sets of a loud alarm. When SIDS kills a baby, all too often it happens in the middle of the night when both parents are asleep and it’s completely silent. Without some kind of alarm it’s almost impossible to intervene in time, so this can be the most important $100 spent on your baby. It saved our daughter’s life, and a quick read through the product reviews shows many more parents with similar saves. Kingii flotation wrist band, $90 After losing a relative to drowning, this engineer designed a wrist band that uses common CO2 cylinders to inflate an air bag for emergency flotation. Unlike a bulky life vest, this thing can be worn easily in or around water, and if used in an emergency it can be easily repacked and reloaded after saving a life. It’s suitable for kids and adults, and easy insurance when working around treacherous bodies of water. Roughly 372,000 people drown every year, and $90 seems a small price to protect those you care about. Wetsuits for kids, $35 Most kids love the water, but little little kids inevitably end up shivering and cold even at indoor pools that are comfortable for adults. The problem is that children have lots of surface area to lose heat through, but very little volume, meaning they get cold very quickly and can’t swim as long as they’d like. A wetsuit ,like this one, fixes that problem and drastically reduces the area needing sunscreen as well. If you’d like to guarantee your child sleeps soundly through the night, consider one of these to turn a one hour trip into a real afternoon outing. Free math and school tutoring - ,Khan academy, - ,promo video Khan Academy helps anyone at any level learn about math, science, and a variety of other school subjects using recorded lectures by skilled professors combined with interactive tests and automated tutoring. It’s hard to oversell this site; everything is free to use, nearly all subjects are covered, you can log in as a student, parent or teacher to monitor progress, and the site even has test prep for all the major tests like SAT and MCAT. The math section that started the site is particularly clever – when a student first logs in they take a ten question test that helps the program figure out their skill level, and then it suggests new math topics and tracks progress while periodically refreshing old topics as well. If you know anyone in school as a student, parent or teacher, tell them about this program. ,Odds are good they’ll thank you for it,. Modern States . org is a way to earn your ,first year college for free,. Also, the ‘big three’ as mentioned by Lee Knott derserve a mention here: “The “Big Three” are regionally-accredited colleges that award massive amounts of credits via testing. They are THE most flexible way to get your degree, both in terms of time and credit. You could start from 0 credits and get your entire degree in less than a year. Most state colleges will limit you to 30 hours, but you used to be able to test out of your entire BA/BS degree via testing. You would do 60 hours via CLEP and then the last 60 hours via a GRE subject test. Charter Oak is a state university in CT, Thomas Edison is a state university in NJ, and Excelsior is a former state university in NY. Same regional accreditation as Yale, Princeton, and Columbia This means there’s no residency requirement. It’s more limited now, and I believe all three require you to take a capstone class online with them before graduating. But think about being able to aggregate credit from a number of different sources. You can transfer in any regionally-accredited classes, DANTES, CLEP, ALEC, StraighterLine, Saylor, ACE-accredited, even free FEMA credits. That means if you take continuing education courses for work you will probably get college credit as well. You can also do a “portfolio” and get credit. This means demonstrating mastery that you learned outside of formal education. Perhaps you play guitar or piano. You write up a portfolio proposal, record yourself, get credit. Some of the colleges also offer credit banking services. Say you haven’t graduated from anywhere, but you have significant credits. Transfer them all to one college and have them all transcripted on one official transcript. They are perfect schools for people who move a lot, military, older adults, and homeschoolers. Many homeschoolers earn their BS through Thomas Edison State while they are still in high school. Lots of them use free Saylor classes to fulfill both high school and college credit. To get ACE credit, you pay $25 and take a proctored exam online.” The drug talk – “,Licit and Illicit Drugs by consumer reports,” The do’s and don’ts of drugs are usually right up there with the ‘sex talk’ when it comes to uncomfortable conversations parents really need to get right, but often put off or miss altogether. Fortunately, consumer reports wrote an excellent book on the topic which is available for free online. The organization has a well earned reputation for impartiality, and it shows as the book talks about what each drug does, how it was discovered, and how it got to be legal or illegal. Having the facts makes smart choices possible, and this free resource is a must read for anyone over ten. $1.25 calculator wrist watch loved by grade school kids – ,Link Kids 5th grade and younger find these to be the height of fashion and prestige. If you want to reward a child with an inexpensive gift that will help them academically, search Google for ‘calculator watch’ and order a few. How to get started in life and live well on less - ,Poorcraft,. Unless you’re lucky enough to start life as a millionaire, most of us have to start out on very small incomes working long hours at unpleasant jobs. There are scams and businesses beyond count built to take advantage of the young and un-educated. If you or someone you know earns less than $50,000 a year, spend $5 and get this book. It’s an easy-to-read graphic novel packed to the brim with useful tricks and tips, plus plenty of humor to keep things interesting. (Cartoon thanks to ,xkcd,) Kerbal Space Program - ,Link This game is a great way to build STEM interest in children and adults as you run a space agency for the ‘Kerbals’ and try to land on the moon or go to mars. All technology in the game also exists in the real world, rockets can be built from parts like Lego bricks and all the physics are as close to real as they can make them. Google ,Sky,, ,Moon, and ,Mars, + ,Stuff in space,, ,Impact earth,, ,LightYear FM,, ,Chronozoom,, the ,100,000 stars, project and the ,scale of our solar system, and the ,scale of the nearest stars,. Bit of an astronomy dump here, but if you want to learn about our universe or teach your children, these are excellent resources. Google Sky, Moon and Mars let you explore these places in the same way Google earth explores the globe. LightYear FM shows how far into space various radio shows have gone, Chronozoom shows the entire history of the universe and the 100,000 stars project is an accurate, searchable 3D model of the nearest 100,000 stars to the earth, and the ‘scale of the solar system’ video shows how small we are by building a huge model in the desert. FanFiction.net, and ,Archive of our Own This is a good way to encourage reading and incentivize writing practice. For any book, movie or TV show, there are fans who write stories about the canon, such as ‘what if she did this?’ or ‘what if this happened this way?’. These works of ‘fan fiction’ can read just like the original work, or can be very different with only characters from the original work. Everyone enjoys some kind of media, and ,FanFiction, is a good way to get them reading about something they already like. In many cases, the instant availability of interesting reading material on any internet capable device boosts reading skills and sets up a situation where writing is undertaken enthusiastically and for fun. We’ve all seen people type out angry rants when ‘someone is wrong on the internet’. Fan fiction sets up situations where the reader will find a story about characters they’re very invested in and say ‘This story is awful! I could write a better story that this!’. And they do. And the posted story gets comments about what the brand-new author needs to work on. And so they write some more to show them, show them all. After several months the same student who had to be forced to write a three page paper will be feverishly banging out ten page chapters twice a month to keep their fans happy. NSF test The National Science Foundation periodically surveys the public to see what they know about science, and the results usually aren’t pretty. The link above is to the ten question NSF test and a series of answers, essentially a canned lesson plan for anyone running a science class at any grade level. The printed test fits on a single sheet of paper and can be used to quickly find out how much your students know and catch up those who have holes in their understanding. +Chemistry article referencing the ,periodic table, and ,nuclear table How different ,engines work Anyone teaching STEM classes or with an interest in engines may find these animated diagrams useful. They’re not the most detailed, but they cover many different basic types of engines. ,This link, shows the standard four cylinder auto engine in more detail. And this link shows more of the peripheral systems like cooling. ,Mechanical link,. Bizarre wheels for projects, forklifts and robots – ,Mecanum Wheel Mecanum Wheels are wheels that allow a vehicle to slide sideways by counter-rotating its wheels. They’re used on forklifts that work in narrow aisles, and in other specialty applications. Anyone building a wheeled robot for a competition should be aware of these because of the performance edge they provide. Fun projects The ,Long Now, foundation building a ,clock, that will run for 10,000 years. The long now is a society dedicated to long term thinking, which involves several projects including a four story tall stainless steel clock that will run for 10,000 years, a project to record all human languages, and another to record old computer operating systems for backwards compatibility. Hundred year ,time capsule for a dollar A simple article on how to build a time capsule from a wine bottle that will last for one hundred years or more. This is a quick afternoon project that lets anyone from grade school kids to adults send a message to people decades or centuries in the future. Free satellite TV for $250 of ,equipment It turns out that free to air satellite TV is still around, and $250 worth of equipment will get you everything you need to watch it. This is a Ku band system (think direct TV sized) and mounts anywhere with a clear view of the southern sky. The programs are a mishmash of low budget shows and international content, but there are hundreds of channels, and they work anywhere you can see the sky. This package is understandably popular with members of the armed forces who want access to their own TV programming while stationed abroad. They also sell the old huge C band dish systems (8 ft across and larger) that still pick up content as well as direct downlink video received by news trucks. Programming varies wildly, but there are some reliable shows – Nebraska, for example, broadcasts their PBS stations down on C band. Telecom – ,how antennas work, + ,satellite coverage map, + ,how bandwidth works,+ ,KU vs C band pro con, + Jumping shoes that give 6 ft of air – ,Kangaroo shoes Know as ‘acro stilts’, ‘power striders’ or ‘kangaroo shoes’, these toys allow for ,ridiculous jumps and let anyone run faster than the world’s fastest sprinter,. They use a composite spring very much like the flexible part of a compound bow and arrow to greatly increase the efficiency of running and jumping, and like skate boarders, are popular for the tricks skilled users do with them.

In ,floor heating tubes, for very cheap winter solar heating (no solar cells needed) If you ever build your own home, remember this trick. Home heating is usually done with forced air through ducts, but this requires a very small area to be very hot (the firebox of the furnace). We all know burning gas and oil gets expensive, but most of the time it’s our only option; solar concentrators can heat water to 150 degrees F, or even 180, but they can’t approach the high temperatures needed for a forced air furnace firebox. However, if you cast plastic water tubing into the floor of the building when its being built, now you have a very larger area that only needs to be warm in order to heat the whole house. A ,solar hot water panel, made up of black copper pipe encased in vacuum tubes can be hooked directly to the system to heat your entire house for free even in the dead of winter. ICF (,Insulated Concrete Forms,) are lego blocks for building concrete homes (,watch a one day build,) For anyone building a new home, ICF blocks are a great way to increase build speed, lower cost, improve insulations and finish with a much stronger structure than a wood only build would provide.

An eight camera system with DVR is a good fix for this, and Z-Modo makes many fine systems for around $200 to $300. Have you ever heard of a break-in that cost less than $300? Normally when you find out about a break in it’s far too late to intervene, and in most jurisdictions the police need three to six months to get the results back on a fingerprint search, and that’s assuming there are prints to find and the person leaving them already has a record with prints to search for. If someone gave you an assignment at your job would you still remember three months later? By contrast, an eight camera system deters some break ins, and if a break in does occur, it preserves video of everything that is taken, and everyone involved. The police normally have a pretty good feel for who is causing problems in a neighborhood, but can’t do much about it without clear evidence. With a camera system you can run the video back while you wait for the police to arrive, and then play them the video with everyone’s faces. Quite often the result is “Hey, I know that guy! Wait here while we go pay him a visit.” In this way a camera system can permanently remove bad actors from a neighborhood and help everyone sleep better.

By now most people have heard of Tesla motors and their three production cars, but if you’re one of ,today’s lucky 10,000, then read on. Tesla makes two $50,000 cars – a sedan and an SUV and one $35,000 sedan and they are the safest cars on earth as rated by multiple agencies. And they’re the fastest production cars in existence. And they’re all electric, silent and have a +200 mile range. And they come with autodrive standard, meaning the day self driving cars are legalized in your state, you already own one. Consumer reports has been rating cars for more than fifty years, and not only did the Tesla score higher than any other car or truck ever, they rated it the best car ever.

When paired with a ,$5 micro SD card and adapter, (not included, must be purchased separately or it won’t run), the camera suction cups to the windshield like a GPS and records everything happening inside the car and visible through the front window. It starts up as soon as the car starts, records about a month of driving, and automatically overwrites the oldest videos so no action is required by the user, just plug it in and forget it. If you are hit by another driver, now you have video of the other person’s mistake and no amount of lawyers can change who is at fault. “It was my fault because I was on my phone? No, actually, the video clearly shows you hit me and I was not on my phone. That, and the GPS and G-force data shows where, when and how hard you hit my car.” In addition to crash uses, the camera also records what happens during a traffic stop, and many users find the police are more polite when they are being recorded. If not, well, you now have video of exactly what happened and YouTube is free. Finally, the micro-SD to SD card adaptor allows you to quickly pull the card after a hit and run, put the video onto the responding officer’s laptop, and show them exactly what happened within minutes of the accident, resulting in an APB and a much higher chance of catching the hit and run driver.

How can I repair my car's paint without spending big money on it?

Options for paint repair range from simple tinted waxes and As-Seen-On-TV miracle pens to multistage treatments matched to your car's exact color. As someone who's capable with a wrench, I went with the latter and tested Automotive Touchup's kit on my pockmarked 1993 Ford Bronco. It costs about $50 depending on which supplies you need, compared to $5,000 for a professional all-over repainting. This collection of aerosol cans and sandpaper is as close as you can get to an appointment at the paint booth. Here's how it works, and whether it's worth it. Supplie IF YOU ARE INTERESTING ; "Save Money And NEVER Buy A New Battery Again"Bring Nearly Any Dead Battery Back To Life Again"All that by '' EZBATTERY ''; https://tinyurl.com/battary-back As with any serious touch-up kit, there are a lot of materials. The box for my black Bronco (color code M1724A) includes prep solvent, rubbing compound, sandpaper of various grits, rubber gloves, a tack rag to pick up dust, pretaped plastic to block messy overspray (like blue painter's tape for your car), and cans of primer, base coat, and clear coat. It all suggests a lot of work, which turns out to be accurate. I watch one of Automotive Touchup's how-to videos and print out the instructions. I bring everything outside, then pick the most unsightly scratches and a rust spot on the hood. I wipe them with the solvent and rag, then tape a perimeter to protect my cherished Eddie Bauer fender badge. STEP 1: ABRASION It feels very wrong to lean into your fender with a folded piece of 180-grit, but that's what you have to do. You make the scratch much, much worse before making it better. I get big, horrible white blotches on the Bronco's fender, door, hood, and rear quarter-panel. But it's cathartic, in a way, to grind down to bare metal in the name of making your car beautiful again. STEP 2: PRIMING On to the sprays. First is the black-tinted sandable primer. It fills in the sandpaper scores with something that resembles the original black, instantly reassuring me. I add three coats to the metal in total, waiting five to ten minutes for each to dry before applying the next. This is a running theme of touch-up work: Spend two minutes painting and then ten minutes waiting to do another two minutes of painting. In this manner, a man could, hypothetically, consume several Founders All Day IPAs in the course of a job. STEP 3: COATING Primer gives way to base coat, which means more aerosol cans. Each application seals in the pigment and protective layers beneath. Between sprays, you sand with ever-finer paper. By the end, you're wet-sanding with 1,500-grit, which feels smoother than a sheet of construction paper. At each interval, you get closer to a factory-finish gloss. The last clear coat finalizes your work with a shiny shell. Step 4: RESULTS The clear coat dries overnight, and I hit my handiwork with the rubbing compound to bring out the shine. And shine it does, which brings me to an unexpected dilemma: The touch-up work looks better than the original paint. Inevitably, nine layers of new paint look better than decades-old factory black. For the job overall, I say, success. In fact, too much success. The instructions say an all-over wax will help it blend. Final step: Give it hell with the orbital buffer and hope it blends. Anatomy of a Scratch Unless the car you're repairing is over 20 years old or was custom-painted,­ the paint is almost certainly a clear-coated catalyzed enamel. Artificially hardened by toxic chemicals, it's stable within hours of factory application. On the other hand, the paint you're applying, whether it's primer, color or clear, is a lacquer. Lacquers dry because the solvent evaporates, leaving the solids behind. While they may feel hard and be sandable within a few minutes, they will continue to shrink for a while. Allow lacquers to dry at least overnight so they can shrink before you add another coat. If you need multiple coats to build up the paint film to full thickness for a repair, one coat a day is best. Of course, be safe. The amounts of solvents used are small, but work in a well-­ventilated area. Make sure to degrease the area with solvent before starting. Cracking the code Somewhere on your car should be the factory-paint code, probably on a sticker or metal plaque under the hood or in the doorsill. This will help a great deal in finding the correct touchup. It's amazing how many similar colors there are in any car manufacturer's palette in a single model year. If you can't match the color in the display of touchup paints at the auto parts store, your next, albeit expensive, step is the parts counter at the car dealer, at least if you have a car that's less than 10 to 15 years old. If you're really stumped, an auto paint dealer can custom-mix you a pint; take in a sample, like the gas cap or a mirror. I've also gotten great matches from expresspaint.com and from their motorcycle counterpart, color-rite.com, where you can mail-order touchup pens and bottles, aerosol cans or quarts or larger cans of matched paint. Clear-Coat Scratch Minor scratches, ones that don't go through the clear coat into the color, or areas of low gloss or orange-peel texture can often simply be polished out with compound. Yes, this removes some of the clear coat, so polish the minimum area necessary or you'll have to respray some of that protective top layer. Thoroughly clean the panel after you're done to remove the abrasive compound. Base-Coat/Primer Scratch You'll need to get some matching paint. This same procedure can be used to repair primer-coat scratches by brushing in a layer of primer first, then sanding the overrun until it covers only the bottom of the scratch. Don't skip that step: You'll have poor adhesion and/or rust.
