Reader [Josh McCormick] hacked this awesomely drunk animatronic Santa. Here’s a cached video link. He purchased the 5 foot tall singing and dancing Santa Claus at Walmart for $50 with the intention of modifying it for an art show. Once he got it home he began tearing it down. He found the brains of the device in the left foot (just like Santa!). The motion control is all analog and there is a hidden potentiometer that controls the dancing rate (jigginess). Josh used a BS2P40 Parallax BASIC Stamp for the digital control of the device and the sound samples were stored on a Quadravox QV306M4. To get the movements in sync, Josh recorded the performance as the sound clip was being played back. The movements were stored on a 24LC515 EEPROM. With some last minute work he got it to the show on time, but it unfortunately broke during exhibition and he did not win. There should be some consolation in the fact that it is on the internet now and will be seen by thousands of people instead of a handful.
