News: Butane Combustion High Voltage Capacitor Launcher

Here's a little gadget I made based on the concept of a potato launcher, a stungun, and a dart gun. The gun uses an explosive gas (butane) to launch a charged high voltage capacitor at a target. The gas is ignited by a small spark, created by a pulse transformer. The trigger automatically fills the combustion chamber with the correct amount of gas, then ignites it with the pulse transformer. The result: a long range stun dart gun.

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 ...

News: Flying Quadrotor Robots Play the James Bond Theme on Real Instruments

Created by the University of Pennsylvania, these bots would impress Q himself. This army of mini quad-copters are controlled with rhythmic precision, a truly awe-inspiring collaboration of music and technology. From playing a synthesizer to drums and cymbals, each robots is multi-talented. The tiny helicopters are equipped with reflectors, making it possible to plot their position using infrared lights and cameras positioned around the room. Check out the video!

How To: Light Up Your Walls with Stars

Everybody loves the stars. Well, I certainly do. As a child I'd spend hours outside during summer nights marveling at the seemingly endless amount of sparkling dots spanning the sky. Maybe you have children of your own and want to create a sparkle in their eyes, or in your own. This tutorial will provide a basic method of bringing the stars inside—at least, in part.

News: Laser Blasts 2 Megajoule Beam 1,000 Times Stronger Than All U.S. Power Plants Combined

You might already know a little bit about what the National Ignition Facility has been up to lately, or what they could possibly achieve. But last week, even the scientists at the Livermore, California station couldn't predict the awesome power that their humongous laser was capable of. NIF's laser is already the record holder for the world's largest laser, and now it can also claim to be the first ever 2 megajoule ultraviolet laser after it generated nearly 100 times more energy than any oth...

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.

News: Playing an Electric Guitar With 100,000V

Video: . I made this Tesla Coil using the myRIO and LabVIEW. It uses electricity to play the music, which can be Star Wars, Harry Potter or even Hunger Games! The music is played by the spark heating the surrounding air (causing it to expand) then the spark turning off (causing the air to cool and contract). This expanding and contracting cause's longitudinal waves - or sound waves.
