Makes lots of fun noise!

Summary

A 4-step sequencer, made from Forrest M. Mims III’s sound synthesizer circuit that uses two 555 timer IC chips, AKA the Atari Punk Console. There are additional switches that allow for changing the sequence pattern, as well as one that switches between the sequencer and a dynamic noise generator controlled by a photoresistor. The custom face plate was made using a semi-transparent acrylic sheet, stenciled and laser-etched from the inside, and then painted.
