Mike's Electric stuff is a website mostly full of crazy high-voltages projects. Mike is a freelance electronic engineer that usually design low power microcontroller-based devices... but in his spare time, he likes to play with various high-voltage things. When playing with some high-voltage generator, he invented a new musical instrument: the spark-o-phone was born.

This interesting device uses some resonant tubes and a high-voltage generator. When an electric discharge, a spark, is done in one of the tubes, the latter starts resonating and produces some sound in a certain frequency, determined by its length, its diameter, and other physical parameters. By controlling in which tube the discharge is done and when, some interesting musical patterns can be done. The results are promising, however I think that Mike should hire a compositor
