This produces sound by modulating a small ball of plasma produced through high-voltage discharge, and it’s this effect that [mircemk] has recreated with his HF plasma tweeter.

Learn how to build a Tesla coil using inexpensive high-voltage generators and Lego, ... Powered by just 6 volts, the output is surprisingly powerful, with plasma arcs reaching a couple of inches.

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 ...

For future projects, [Jay] intends to use this setup to drive a large voltage multiplier, also noting it can be used with Tesla coils and plasma balls with the right additional hardware.

She worked alongside the band ArcAttack, which uses Tesla coils to make music. She took to stage (check out the video above to see it for yourself), holding her arms out and drawing in bright ...

It’s possible you’ve seen the following affected by sound before: a chladni plate, water, ferro fluid, a plasma ball, a ruben’s tube, and a Tesla coil. It’s hard to believe you’ve seen ...

Guiding high voltage arcs in the Tesla coil. Finally, let’s take a look at a technique guiding the high voltage arcs of the Tesla coil by using laser-induced plasma filaments in air 5. A terawatt ...

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 120 V wall current to roughly 10,000 V. The ...

If you’ve never seen a Tesla coil in person, it’s a remarkable experience. Purple plasma flashes in unpredictable, wide-reaching bolts. The sound cracks with more fearsomeness than a whip. The ...
