Tesla coils are one of those builds that capture the interest of almost anybody passing by. For the naïve constructor, they look simple enough, but they can be finicky beasts—beasts that can ...

The primary side of a Tesla coil is usually a handful of turns of thick wire to handle the current without melting. This build runs at two or three amps, giving a primary power of around 150 Watts.

Tesla coils do the same thing, but with a much more dramatic change in voltage. First, they employ a pre-made high voltage iron core transformer to go from 120V wall current to roughly 10,000V.

Small Tesla coil designed for use by medical profession, 1897 Visit Life and Legacy to get the full story behind the Tesla coil. View Tesla coil patent 454,622 .

When they are played, the Tesla coils emit a soft buzz before unleashing long tentacles of electricity. These sparks not only serve as a dramatic way to light up the stage, but also "sing" musical ...

He’s also collaborating with Tesla coil performance artist Austin Richards of Santa Barbara (a.k.a. “Dr. MegaVolt”) on a two-story, 120,000-watt sculpture equipped with a ladder for people ...

Tesla coil design. I am a believer in using short cuts in designs as long as they are technically solid and robust. In designing a Tesla coil, there are numerous equations and formulas that must be ...

Nikola Tesla was a visionary thinker, making experiments which still aren't fully understood today. But even the inventor of AC current wouldn't have foreseen this Flash Gordon style wireless ...

How Tesla coils generate high-voltage electrical fields. (Image credit: by Ross Toro, Infographics Artist) How it works. The power source is hooked up to the primary coil.

The Tesla Coil is one of the most iconic and fascinating inventions of all time, created by the legendary inventor Nikola Tesla. But what exactly is a Tesla Coil, and how does it work? In this ...

ArcAttack’s Tesla coils can put half a million Volts into the torus. Then they funnel that energy through another inductor to control the current and produce massive sparks.

Everyone loves a Tesla coil. Photographer Rob Flickenger is such an aficionado that he photographed one blazing à la "bullet time" from The Matrix. 100+ ...
