Zener Click

A passive drum machine based on Zener diode breakdown noise, no external power supply is needed, three inputs support trig, gate, audio and other voltage signals, only need voltage higher than 3.3v.

The three inputs violently mix and fight each other interfering to get varying rhythms at the outputs. The knob adjusts the output volume. The zener click is a by-product of the development of the hadouken.
