Zener Click

A passive drum machine based on Zener diode breakdown noise; no external power supply is needed, with three inputs supporting trig, gate, audio, and other voltage signals—only a voltage higher than 3.3 V is required

The three inputs violently mix and fight each other, interfering to produce varying rhythms at the outputs. The knob adjusts the output volume. Zener Click is a by-product of the development of Hadouken.
