I had a few microphones lying around and I decided to build those boards.
This is a clapper switch with 2 open drain outputs, able to power lights or other DC loads. It has a maximum of 30 volts input and load switching up to 30V/20A. Pay attention to heat dissipation at those power levels!
It has a microphone on board that detects sound spikes, like hand clapping, finger snapping, or metal objects hitting one another. Hand clapping is the most effective way of activating the switch; detection range is about 1m (3ft) from the microphone. Mechanical vibrations trigger the switch also.
It comes fully assembled and tested by me.
