@Quadraphonicsoul I do not have a schematic yet. but the sound making part is quite simple, The output (pin 3) of one 7555 astable oscillator is connected to the voltage control input (pin 5) of the other. see wikipedia 7555 article for astable diagram (hmm, youtube won't let me post link... sorry)
this thing is sweet. do you have a schematic for it?
