Force Lightning: How to Make a Shocking Cookie Jar Any Sith Lord Would Be Proud Of

There is nothing more annoying than a greedy roommate. It's absolutely infuriating to wake up and find the cookies your mother just made for you gone without a trace. Your favorite drink is empty and the homemade meal you worked so hard on the night before is nowhere to be found. This irked me so much that I made this shocking cookie jar. When a cookie burglar touches the side and the lid of the jar simultaneously, a small electric shock stops them in their tracks.

How To: Protect Your Door with High Voltage

In this article, I'll show you how to create a simple yet effective way of scaring off intruders. Of course, there are methods around this approach, but it's great for office pranks and general fun. The project requires a little background knowledge in electronics and circuitry, like reading schematics and using a soldering iron.

News: No more HDMI cables?

Ok, I know nothing about this, but if this is true, does that mean we can toss out the millions of cables that are hiding in closets, garages and basements? According to the article, there's going to be HDBaseT, which can carry both video and audio signals, and a network connection, a USB connection and electricity with a single cable.

News: DIY Snowflake Cultivation with 2,000 Volts of Thermoelectric Cooling

Snowflakes aren't much to look at during a storm, but when you look real close, you can see just how marvelous they really are. But winter is over and most of us can no longer enjoy the intricate nature of ice crystallization, unless you're sticking your head in your freezer. Or unless you build your own snowflake cultivation machine, which shoots 2,000 volts of electricity through a cold, moist chamber.

Red Wine: The Secret to Superconductivity

We've all heard of the power that red wine holds. It can help lower risks of heart disease, boost your brain power, and can even recharge your car battery. But last year, a group of Japanese physicists made headlines when they announced that they could induce superconductivity by soaking metals in red wine. But why red wine?

Dueling Plasma: Singing Tesla Coils' Shocking Battle to the Death

Tesla coils are electrically satisfying in so many ways. But what happens when a guitar-playing city coil has a run-in with a backwoods, banjo-playing, inbred coil? A musical duel to the death! Watch these two Tesla coils battle it out as they play Dueling Banjos. Shocking. Just shocking. Okay, so it's no secret that Tesla coils can create a wonderful light show of electricity, but by modulating the frequency, they quickly turn into powerful singing Tesla coils—the key to any electromaniac's ...

How To: Make a Mini Cannon From a Lighter

I love this project. It involves fire, projectiles, electricity, and is easy to put together from commonly available parts. This mini cannon fires airsoft pellets, is fueled by alcohol, and is made almost entirely from parts found in a standard BBQ lighter. The total cost is under $5. About half of the BBQ lighters out there have a divide in the gas reservoir which makes them not work for this project. In case you have trouble finding a suitable lighter, the exact one I use in this video is a...

News: World's First Bend-Sensitive Flexible Smartphone

Apple's iPhone is considered one of the best smartphones in the world. Many cell phone makers have tried to take down the juggernaut, with some Android-based devices coming close, but in order to become an actual iPhone killer, something revolutionary needs to happen in the mobile world. And Human Media Lab (HML) may be the ones to make it happen.

How To: DC Versus AC and the Diode

Direct current (DC) by definition flows in one direction. Alternating current (AC), on the other hand, periodically changes direction, or reverses polarity. It is indeed possible for a portion of a circuit that is normally DC to periodically change direction, or reverse polarity like an AC circuit.

News: Train the cat to poop in the toilet

How to train a cat to use a toilet - really. I could not invent this stuff. When I first saw this video, I knew my life would never be quite the same. This ranks up there with the invention of electricity or the discovery or DNA. Now, I don't need to smell that litter. I don't have to change it. I don't have to buy it in the store anymore.

How To: Mine Bitcoin and Make Money

Bitcoin is a new currency built off "Satoshi Nakamoto's" (alias) 2008 Bitcoin white-paper. Bitcoin provides its users with a way to make peer-to-peer (P2P) transactions without having to use a bank as a mediator. There is no middle man, no corporation backing it, and no one has access to your money, except you. It's decentralized from government, run by the people, for the people.

Altruistic Hacking: The Rise of the DIY Radiation Detector

Understandably, the tragedy in Japan has substantially risen the level of worldwide radiation-related hysteria. So much so, as an alternative to stampeding health food stores for iodine tablets, crafty individuals and organizations are hacking together personal radiation detectors. Rather than relying on the government, the creation and modification of handheld Geiger counters provides a self-sufficient solution to today's questions regarding radiation. Profiled below, three admirable organiz...

How To: Prevent Post-Earthquake Nuclear Meltdown in the US

After getting slammed with a crazy-big earthquake/tsunami, the Japanese nuclear plant Fukushima Daiichi might be on the brink of meltdown. Not as bad as Chernobyl, but maybe as bad as Three Mile Island. Nobody wishes such a disaster on anyone...anywhere in the world. In the US, there are about 100 nuclear facilities, about 8 of which are located near hot beds of seismic activity.

News: Carnivorous Furniture Eats Flies and Mice for Energy

PETA wouldn't consider James Auger and Jimmy Loizeau's ingenious flypaper clock very eco-friendly, but I might beg to differ. The clock doesn't require any electricity or batteries. Instead it captures flies and converts the bodies of the dead insects into energy. Eight dead flies makes for roughly twelve days of power. Not bad.

How To: How Anyone Can Retire Early & Wealthy, Part 1: CDs

I'm pretty sure that it's a universal dream for everyone in the world to retire early. Who wants to to be stuck with the rest of the country and retire when you're almost 70 years old? You heard me right, 70! Most people can't go out and do the things they love to do by the time they're 70, unless they've been practicing good health and exercise their entire life.

How To: Light Up Your Whole House with This DIY 'Nuclear Explosion' Chandelier

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...

How To: A/C Broke? Keep Your Car Cool with This DIY Solar-Powered Air Conditioner

If a solar-powered air conditioner that requires no electricity or moving parts sounds to good to be true, well, then you're not as ambitious as this clever high school student. Instructables user Fozzy13 put together an awesome DIY tutorial on how he built his own air conditioning unit in his car that works using the principles of evaporation, convection, and capillary action. This air conditioner works by using sunlight to heat air at the bottom of the unit. The hot air rises, allowing the ...
