Circuit-bent Value Village toy — It pretty much sounds like a nightmare, but a few nice tones are achievable. I added a knob that effects the pitch, a mono RCA out, on/off switch, and a switch that changes the capacitor used to play the note. The capacitor switch effects the decay of the note. Who knew?
fat beard found this at Value Village for a dollar. Worth every penny. It needed an on/off switch for starters. Looks like I should’ve wired the LED to a voltage source that comes AFTER the capacitor. MORE WORK? YESH MLORD.
edit: heretofore-after referred to as the “Red Unit”
edit 2: finished! see demo youtube.
I guess I should just be happy this still turns on.
