Class E Audio Modulated Tesla Coil
posted May 13 2010 1:01.46




Guys at EasternVoltageResearch made a tesla coil kit that was specifically designed to reproduce high quality audio through plasma modulation. In otherwords, the high voltage arcs from the Tesla coil are modulated so that they create audio sou...

SRSG Tesla Coil - 1kVA NST
posted May 4 2010 9:07.16




rmcybernetics build a 1kW Synchronous Rotary Spark Gap tesla coil that is capable to produce arcs up to 74cm! The whole build is made with quality in mind and of course the result is equivalent. You can find very detailed step by step info and schematics at rmcybernetics page.

A Singing Tesla Coil
posted April 9 2010 6:17.20 by Giorgos Lazaridis



This Tesla Coil is playing the Monkey Island theme. The RF is generated with a Class-E MOSFET stage with controllable Frequency. The sound is modulated on the gate signal of the MOSFET via PWM. The sound is then emitted by the arc itself. The sound is very clear.
