P.B.D.B. tech notes

The P.B.D.B. figurine is a solid aluminum cast that I had laying around from my foundry days.  I used it as a capacitive sensor so that I wouldn’t have to mount a big ugly button on the belly.  The sounds come from an Adafruit WAV shield, and the water is moved via windshield washer pump.  I was amazed by how much current those things draw – I had to put a 5A power supply in the box to get it running.
