nAnOnAnD

Toy synthesizer on homebrew PCB.

Cheap and patchable digital glitchy sound synthestizer made with a CMOS 4093 NAND gate.
Unprocessed audio from mini speaker recorded with a microphone.

Schematics based on info found on the internet and in Nicolas Collins book handmade electronic music, mixed with some of my ideas.

Jack-out mod:

You don't need IC2, C10, dip 8 socket and minispeaker. You do need an extra 10 K resistor and a jack plug. 10 K resistor should be between the 2 holes left (above in photo) from IC2. Jack signal goes to pin 3 of IC2, jack ground goes to pin 2 of IC2.
