Atari Punk console is an astable square wave [[oscillator]] driving a monostable oscillator that creates a single (square) pulse. There are two controls, one for the frequency of the oscillator and one to control the volume. The controls are usually [[potentiometers]] but the circuit can also be controlled by light, temperature, pressure etc. by replacing a potentiometer with a suitable sensor (e.g., photo resistor for light sensitivity). Most of the time there is also a power switch (often a toggle switch) and a volume knob. |

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. There's needs to be something to limit the current through the pots and pin 7. Add a series resistor to each of the pots, e.g. 330 Ohms at 9 Volts will limit the power to just under a 1/4 Watt, (the rating of most pots).<ref>[https://www.diystompboxes.com/smfforum/index.php?topic=65396.0 Atari Punk Console - Sparking Pots?], DIYstompboxes.com</ref><ref>[https://www.diystompboxes.com/smfforum/index.php?topic=71808.0 Help!
