Buzzwired for sound!

Hi Richard,

My Buzzwire project might do what you want, as part of it is recorded sounds of a cat and dog!

Take a look here:

IssuesT about Adding Sound Using Same PSU.

There are possible issues regarding the addition of sound when using the same PSU as the motors in the model in question: Unpleasant mains/rectifier hum and suppression of the models motors. The mains hum can be reduced by the addition of 100nf-470nf capacitors across the rectifier connections(mains/battery transistor radios have them). I would also power any sound pcb via a regulated supply to reduce noise.
Motor suppression usually involves the simple connection of a 100nf-220nf capacitor across the motors terminals(for dc motors).
