## Schematic

## Reference

https://sdiy.info/wiki/Atari_Punk_Console

## Note

To address the problem described in "Problems" above, where "With a pot turned down to minimum, because internally the 555 shorts pin 7 to ground during parts of the oscillation, there will be a short circuit across the battery.", a 330-ohm resistor is connected in series with each pot.  

    

It certainly affects the oscillator's frequency, but the effect on the audible range seems minor when experimented with it.
