The doorbell that plays WAVs

DoorbellNot a complete how to, but a start for making your own doorbell that plays a sound of your choice - "When the doorbell to our company office broke, my boss half-jokingly suggested we replace it with one that could play WAVs. We didn't find a doorbell with the capability of playing WAVs ... but we found one that had a built-in microphone and could record its own chimes. Armed with a soldering iron, my colleague Mark and I set about bending Funki Tech to our will." Thanks Paul! Link.

Of course, the next step in the project is to add a fingerprint reader to the doorbell button and play different sounds depending on who is knocking.
