This is a square-wave oscillator with LFO modulation. It is built into an old dome light which is turned on by pressing down on the dome itself.
There are controls for frequency of the oscillator and speed of the LFO. The light pulses in sync with the LFO and makes neat shadows of the wires inside.
Audio output via an 1/8″ inch jack.
Powered by 4 AA batteries.
