His printed coil generates some pretty serious streamers — a foot long (30 cm) in some cases. The secondary of the coil has 6-mil traces spaced 6 mils apart, for a total of 240 turns.

To investigate the electrical realm of high-frequency and high-voltage, Tesla invented an apparatus that pushed the limits of electrical understanding. None of the circuit's typic ...

[Zach Armstrong] presents for your viewing pleasure a simple guide to building a solid-state Tesla coil. The design is based around a self-resonant setup using the UCC2742x gate driver IC, which is… ...

Figure 3 Compared to the Tesla coil, the Marx generator has a simpler physical construction – but there are still high and dangerous voltages, of course. Source: Electric Stuff – UK You can also buy ...

What happens when high-voltage science meets backyard engineering? We test out laser bazookas and real working Tesla coil ...

The grounds open at 6 p.m. and beginning at 6:30 there will be museum-provided entertainment: demonstrations of a Van de Graaff generator and small, hand-held Tesla coils; and hands-on activities ...

Because the Tesla coil project took almost five years to build, film editor Sabrina Zanella-Foresi had an abundance of footage that she winnowed to the 30-minute documentary.

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.

At the 1998 installment of the tribal-campout-meets-art-festival known as Burning Man, Klinge marveled at the fireworks produced by a 16-foot-tall coil sculpture and knew he had to build his own.
