This project consists of three circuit boards with a row of 32 LEDs on each (actually 64 LEDs because they’re double sided). The circuit boards are mounted radially in the spokes of a bicycle wheel and batteries near the hub supply power to them. The LEDs are controlled by a microcontroller that measures the rotational speed of the wheel by way of a hall effect (magnetic) sensor. As the wheel rotates, the microcontroller turns the individual LEDs on and off in such a way that a static image appears to float inside the wheel.
The 4 mechanical mirrors are made of various materials but share the same behavior and interaction; any person standing in front of one of these pieces is instantly reflected on its surface. The mechanical mirrors all have video cameras, motors and computers on board and produce a soothing sound as the viewer interacts with them. Thanks Kakkewiet!

“Taking things apart is just plain fun, but there’s also a lot to learn about how to build a foolproof Linux-based appliance. Break out your Torx drivers and take a closer look at TiVo’s inner Linux workings. Examining the TiVo system reveals how one company made the transition from desktop operating system to embedded system.”
