Atari Punk Console/Stepped Tone Generator

I figured it was about time to try out this classic schematic, originally designed by the venerable Forrest M. Mims III.  I’ve included my own schematic using photoresistors to control the unit’s parameters, as well as allow for CV control from my little sequencer.  Video also uploaded to YouTube.  Overall, a fun and easy build.  😀

I also added toggles to switch the photoresistors on and off.
