“This is experimental electronics project to turn your old joysticks into nice sound devices with no external sound source needed.
1.Potentiometer (commonly pc or mac) joystick with autofire circuit. (C64, Atari and some other old joystics are different and there are no potentiometers inside them.)
Here in Finland these you can find these very cheap from fleamarkets. You recognice them from smooth and quite long movements of the stick and of course a switch that says autofire or turbofire.
