chaosz is the Kulturgüter-Schuppen classic of dBm instruments. It was created in 2010 at the first Circuit Control Festival  Dresden in the legendary Ostpol location. CHAOSZ (CHAOtic OSZillator), is a simple astable CMOS oscillator that can be made chaotic by power starving and variable filtering of the power supply. The sound ranges from a boring square wave to stomping locomotives to clucking chickens...

CHAOSZ FAQ

why this exotic CD4085 chip ?

what's this Bruce Willis "die hard" capacitor ?
it creates a "power starving" envelope after switching off chaosz
