Doorbell-sounding Toy Synth Circuit Bend: Phase 1

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.
