Avr stk600 singing arc. from ATMEL MCU + IGBT

Singing spark! Atmel At tiny MCU in STK 600 developement board running the square wave signal at the frequencies heard, swithchin is done by IGBT pulled out of Allen Bradley industrial drive, and the proection is in a form of simple high power diode the spark gap is minimized to limit the current and prevent the copper conductor from melting, when the gap is enlarged there's heavy ionized air smell , huge arc and tons of noise.

I will work on actually putting through a much more complex waveform possibly some sort of a tune :) through a filter of some kind to let the high band through.
