The USB Doorbell lets you swop out the standard chime in your doorsy's push-button and replace it with whatever nonsense pleases you. You simply upload a .wav file of up to thirty seconds via USB and away you go. Requires three AAA batteries and standard doorbell wiring (it has no speakers, wireless capacity, etc) and is designed for a low voltage circuit (4-24 V). Video of the audio after the jump. $100.
