Spoke POV is an easy-to-make electronic kit toy that turns your bicycle wheel into a customized display! The project includes a free schematic design, open source software for uploading and editing stored bitmap images, and a high-quality kit with all the parts necessary to build your own.

These instruction assume you purchased the kit or at least the PCB. All parts are through-hole and this should be a very easy project, even for a beginner. Still, if you’ve never soldered before, this tutorial is really awesome. If you’re part of the new streaming-video-generation, this set of soldering mpegs may do you:
