What feature would we most like to see in the robots of tomorrow? Why, the ability to interact with human beings without crushing them to death, of course. Happily, thanks to a new pressure-sensitive synthetic skin technology, the dream is within reach:
It's one of the most popular queries on the web, meaning the wet electronic disaster is likely a common mishap. There are many answers out there, but if you're lucky enough to have never googled it, pay attention now. You never know when you may drop your cell phone or iPod in the sink...
MacGyver. How can he not be a WonderHowTo hero?
Chemical engineers at Cornell have created a small device that may one day turn troops into real life spider-men. The device would cradle in the palm of the hand, allowing troops to scale walls. It uses an adhesive inspired by the Floridian leaf beetle, an insect that "can adhere to leaves with power 100 times stronger than its own body weight".
Infiniti is like no other car, it has emotion, it has soul, it inspires. There's a difference between being physically transported and emotionally moved, and you can tell them apart when you sit inside this magnificent automobile. Although the Infiniti is like a dream car, it has its problems just like any other brand of vehicle. There's maintenance, minor repairs, major repairs, needed replacement parts, oil changes, headlight adjustment, low tires, transmission and everything else you can t...
If the letters on your laptop keyboard are faded or dirty, cover them with strips of washi tape. A high-quality, decorative tape made of rice paper based in Japan, washi tape is an extremely versatile craft tape known for its eye-pleasing decorative patterns and low-adhesive quality that makes it easy to unstick, reposition, and reuse again and again.
Gardening hose starting to leak? Don't throw it out just yet. Cut it up into smaller lengths and slice it open to use the hose as a protective barrier for outdoor electrical cords, or as added grip on a metal paint can handle.
NK5 is a genuine wizard with an old monitor. He's hacked together everything from an electric kitty fence to a Halloween hologram using the guts of an old CRT.
As some of you Mad Science readers will remember, we recently covered the separation of water into hydrogen and oxygen using electrolysis. Passing a current through water can rend it apart, but we can also recombine that oxygen and hydrogen to make electricity! This is the principle behind those vehicles run by hydrogen fuel cell engines.

I'm sure most everyone has some kind of fluorescent light source in their home; those long white tubes that emit a bright white light when turned on, or maybe a few of the CFL power-saver bulbs. These bulbs actually require very little "power" (i.e. a high voltage:almost no current ratio) to emit light. In fact, static electricity is enough to make them flicker. Inside these tubes is a gas, and when electricity flows through that gas, it gets "excited" and produces light.
I've come across a few very stubborn Xbox consoles in my day. A previous Null Byte demonstrated how to fix the Xbox with just eight pennies and some electrical tape. But if you've got one of those hell-born boxes that just refuses to be fixed in any way, shape, or form, there is always one last ditch approach. I'm talking about the infamous "towel trick". It works over 90% of the time, from my personal experience. Though, please note: This is only a temporary fix.

(Difficulty Level: from Newby to Expert) Digital cameras can produce freaky sharp images—it’s one thing that sets them apart from film cameras. A DSLR doesn’t have grain, it has noise—and that sounds a lot less charming for a reason. If you shoot at a low ISO, high f-stop and fast shutter speed, you can wind up with a super sharp image that might look great even on a billboard. But sometimes, sharp isn’t everything.
Were you horrified when Gwyneth Paltrow's head ended up in a box in Se7en? Do you share Harrison Ford's opinion that Han Solo should have died in Return of the Jedi? Think Kurt Russell could have handled aliens better in The Thing? Well, sorry—you're out of luck. There's nothing you can do to prevent William Wallace's beheading or Carrie's mayhem. But thanks to MyndPlay, controlling the plot to future films is totally possible.
Running this World has prompted me to think about MTG on a deeper level than I ever have before. In attempts to contextualize it, explain it, research it, and understand the parts of it that I don't yet understand, I have come to an unexpected conclusion: I'm old.
Congrats to WonderHowTo Jackass 3D prank contest winner Grayson Robison! His winning idea: Connect Knoxville to a real life Operation game with shocking devices. Every time a player screws up and the buzzer goes off, the "patient" gets a burning shock to the correlating body part.
Solar panels are an amazing invention. Catching energy from the Sun before it even enters Earth's food chain, photovoltaics are like an all-natural nuclear power plant. Unfortunately, the constituted parts of a solar panel are rare, valuable, and subject to the coercive forces of market competition.
Bikes are a great form of transportation. They use human energy more efficiently than any other machine. You can keep it in your closet or hallway. You can even take it on the train in a pinch. However, this portability is also the bike's biggest draw back. If you own a bike in the city, chances are it will be stolen. Locks barely deter thieves armed with bolt cutters and crowbars. Throw the bike thieves for a loop and make a tilt-sensitive alarm. It will hopefully startle your bike's assaila...
Our hacked Kinect series has demonstrated amply how the Kinect is changing the worlds of business, art, medicine and robotics. But where does it go from here? That will be determined by the thousands of dedicated DIYers out there doing work like you've seen here over the last week.
Sure, you go online to email and shop and do research. But have you ever been curious about how the internet actually works? Don't worry, you don't need a degree in computer science to get a handle on how your info gets from point A to point B. Learning the basics of the internet will give you a whole new appreciation for all those emails and chat messages that seem to magically appear. Get ready, because we're about to enter the wonderful world of digital data!
Whenever we make a homemade circuit, we use what are called through-hole components. Any components with long metal leads is a through-hole component. They are great for soldering to, but it's tough to fit enough through-hole resistors and capacitors into a smartphone. To get those last microns, we have surface-mount components for SMDs (surface-mount devices). These are all of those teeny, tiny things you see when you crack open your digital camera or laptop case.
Fans of Doctor Who know that the sonic screwdriver is the ultimate tool. It can unlock doors, turn on lights, detect life forms, solder wires, and sabotage weapons.
It turns out that the popularity of soft circuit electronics has leaked out of the interwebs and into the hands of the U.S. military. Soft circuit electronics allow you to literally sew electronics circuits into fabric using flexible conductive thread instead of wire. Soft circuits can be used for all sorts of fun projects, like the TV-B-Gone Hoodie and the Heartbeat Headband.
In my second article of the laser weapon series (see the first part here on CO2 lasers), I'll be expanding on the potential of pulsed lasers.
In this series, I'll be exploring electromagnetic weapons, how to build them, their function and application to the future, and the amazing possibilities electromagnetism has to offer. First, the electromagnetic pulse generator, or EMP. You've probably heard of these before, and their devastating effects on electronics. A simple EMP consists of a capacitor, transformer, trigger, and coil of copper wire. This, when triggered, would produce an intense magnetic field for a brief period, similar ...
In this article, I'll show you how to build a coil gun. A coil gun is a device that fires magnetic projectiles at high velocities, using electricity. Coil guns require no explosive propellant, therefor can be fired an infinite amount of time, providing that there is ammunition and available electricity.
Halloween will be here in just over a week, which means next week these Scrabble Bingo of the Days will become more horrific. This week, there's just a few relevant Halloween seven-letter words for your Scrabble vocabulary, referencing witchcraft and one of the eeriest horror movies of all time, The Thing (not this year's version).
I love my laptop. It goes wherever I go. Unfortunately, that means that it also gets pretty grubby after a while. The screen gets dusty. The frame gets smudgy. The spaces between the keys fill up with crumbs of questionable origins. And my desktop? That thing is a dust bunny magnet.
A flashlight is one of those things you rarely need, but hardly ever have when you do. The normal-sized ones are unwieldy to carry around, and the small ones that you keep in a purse or car are easy to lose.
If you're the kind of person who misses the bright, sunny days of summer during the colder months, Michail has the perfect addition to your home. He built this "Nuclear Explosion" Chandelier that's as bright as daylight, so you can recreate the feeling of summer, no matter what time of year it is. It puts out 99,400 lumen (a typical 60W light bulb only produces 800 lm), so it takes quite a bit of electricity to run. Michail used 7 metal-halide lamps, which are much brighter and more energy ef...
A smartphone is pretty much useless with a dead battery. When you're out and about, it can be hard to find a place to plug in (if you remembered your charger, that is). But this DIY solar panel backpack made by electrical engineer Theodore Protasiewicz will help you use the scorching sun to your advantage and make sure that your gadgets are always ready to go. Theodore started with just a normal backpack, some solar panels, 18 gauge wire, and a USB port and hacked it into a traveling solar ch...
Rain can make for an amazing photograph, but it can do disastrous things to your equipment. This super simple DIY cover from Purple Summit Photography will keep out the rain so you can capture beautiful shots no matter the weather, and it's made using things you probably have lying around.

Michael Faraday was an English chemist and physicist - a bona fide electromagnetism and electrochemistry genius. Without him, men couldn't walk on live electrical wires. Wait, what?
Hotly contested video. The question remains, is the science behind the potato fire bonafide or bogus? We have yet to try it over here at WonderHowTo, and the comments thus far haven't indicated a solid verdict. Try it out and let us know! Is this a hoax? Or can you truly start a fire with a potato, salt and toothpaste?
Old Hard Drive + MP3 player = Music This equation just doesn't make sense. If you're an iPod addict, the HD element is redundant! Well, take a second look at what constitutes a speaker and what a hard drive is made of. They are more alike than you'd think.
WonderHowTo is made up of niche communities called Worlds. If you've yet to join one (or create your own), get a taste below of what's going on in the community. Check in every Wednesday for a roundup of new activities and projects.
Camera manufacturers release new versions of the same cameras, mostly point-and-shoot models, as frequently as Detroit's auto industry upgrades minivans. They also add new lenses regularly, upgrading previous models with adjusted zoom ranges or the image stabilization feature. The same goes for tripods, portable flashes and even camera bags.
