In this article, I'll show you how to make a high-powered, long-range, air-powered rocket gun. This launcher is based on a sprinkler valve, a modified propane tank, and a few other components. Though not hard to make, this device is VERY dangerous! The rocket can seriously harm, if not kill any living thing it's shot at. Here's a video of it in action, quite an accurate shot by my friend Chris... Parts
I'm back with the third part to my laser weapon series (see part one and two), and I'll be explaining the function, application, and potential of semiconductor lasers, aka laser diodes.
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.
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.
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 ...
Electrical engineer Greg Leyh and company are currently creating a pair of 118-foot Tesla coils! The largest coil built to date is an 18-story tower constructed back in 1903 by Tesla himself, but Leyh has decided to not only recreate the huge coil, but double it in size. The project goes by the name of "Lightning on Demand" and is currently being constructed on an 81-acre plot in the Nevada desert. Once it's finished, the pair of coils will output 10 million volt acres 100 yards long—the size...
One of the latest home-improvement gadgets out there today, smart lighting, has become more popular as prices come down. That being said, its still quite a penny to shell out. In this article, I'll go through a few of the top products out there today, including the Philips Hue, Belkin WeMo, and Lifx.
Tesla coil music, a method of modulating the frequency of a Solid State Tesla Coil to produce music. The result is an amazing lightshow of electricity, paired with music!
Since its creation, Arduino has been growing exponentially more popular as DIY enthusiasts and Makers alike realize its potential. As new versions of the device are released, many easy-to-use peripherals are showing up on the market also.
National Ignition Facility
Most of your who visit Fear of Lightning are probably well familiar with laser weaponry, thanks to Christopher's three-part series covering carbon dioxide, flashlamp, and semiconductor lasers. Another type of laser currently being developed as a weapon is the fiber laser, which is compact and efficient, but much weaker than a chemical laser. Fiber lasers are more commonly used in laser cutting and marking, telecommunications, spectroscopy, and of course... music.
What Is Graphene?
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.
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!
Hi everyone! I love the ideas what you showed us and the how to make does electric stuffs, but I had some ideas:
