The germanium transistors is supposed to have some special mojo. PNP types are more common but require either a battery charge pump to create a reversed power…

Glitchstorm at Noisebridge!
Glitchstorm is an Arduino based bytebeat synthesizer. In short this is a noise maker that generates chiptune style sounds. It’s a lot of fun to play with! In more detail, bytebeats are music generated with software via non-linear algorithm. The sounds a lot like 8 bit chiptunes. The sounds evolve over time, and can sound…
