The Faux Plasma Etcher (AKA Small Continuous Wave Tesla Coil)

This is the first not-really-tiny or prone-to-explosion MOSFET tesla coil that I've built. It was more or less camoflaged as a "plasma etcher" while it was first being built, but after it was featured as part of a high voltage electronics demo at the University of Washington's 2006 Engineering Open House I didn't bother claiming it was anything other than what I really wanted it to be all along: a more or less purposeless Continuous Wave 500kHz high voltage power supply with very poor frequency and voltage stability. It's Great fun!
