Master the Power: How to Shock People with Your Fingertips

In this article, I'll be showing you how to make a simple yet effective static electricity generator. Basically, this device allows you to carry a constant static charge on your body and discharge it on anything grounded or of opposite polarity. The electricity generated is around 8-10 kV, at a very low current. The shock is enough to startle your friends, just like a static shock from a trampoline or carpeted room. You'll need a little experience in soldering and circuit design to build the ...

News: Space Painting with a Tesla Coil and One Million Volts of Electricity

Nikola Tesla. He was the man behind some of the greatest inventions of all time, including radio and alternating current. But perhaps his most visually fascinating invention is the Tesla coil. While maintaining a low current, it can produce dangerous high frequencies and voltages that can well exceed 1,000,000 volts, discharging it in the form of electrical arcs very similar to lightning.

Coming Soon: Charge Your Cell Phone by Screaming at It

The Telegraph reports that a team of researchers lead by Dr. Sang-Woo Kim of the Institute of Nanotechnology at Sungkyunkwan University in Seoul have developed a method for converting the energy from sound into electricity. They've applied the research to the charging of mobile phones, and while you don't have to yell with all the emotion and fear exhibited above by Drew Barrymore in Scream, it sounds like the more energy the better. Dr. Sang-Woo Kim says:

How To: Install perfect pathway lights

Looking for a front-yard upgrade that'll have visitors beating a well-lit path to your door? The answer is an easy to install pathway lighting set. Too often, we're forced to choose between form and function. But when it comes to the route that leads to your front door, you can have it both ways: a pathway lighting system that combines the safety and security of good exterior illumination along with decorative elements that enhance your landscaping. Even though you might not have any experien...

How To: High Voltage Happiness? How to Make a Negative Ion Generator

In this article, I'll show you how to build a simplistic circuit to generate negative ions. Negative ions have been known to contribute to fresher air, happier mood, and general health benefits. However, they also look amazing in the dark (check out the photos below, purple plasma is amazing!). And if all else fails, they make a cool nightlight. If you've ever been around a Tesla coil, cathode ray tube TV or sometimes even on a trampoline, you've probably noticed that smell; the smell of "sta...

How To: Make a DIY Magnetic Hammer

So simple yet so brilliant: Designer Jung Soo Park found a way to improve a “run of the mill” hammer by incorporating a magnet at the end of the handle. It holds a few nails while you’re working and if you drop a few on the floor, the magnet makes it easier to pick them up.

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.

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.
