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.
Specs:
- Can be used with road, mountain or BMX wheels!
- 30 LEDs on each side (22 for BMX) x 256 radial pixels
- Runs on 2-3 AA batteries for 10 hours or more, assuming 3000mAh alkalines and 50% image coverage.
- Can run on rechargable NiMH AA’s
- Comes with high-brightness red LEDs, but can be upgraded with green, blue, amber, etc.
- Automatically shuts off after 3 minutes
- wxPython based software runs on any Linux or Windows PC with a parallel port
- Design is all through-hole parts, perfect for a first time kit builder.
- With one spoke, total persistence at 15mph. Two spokes, 10mph. Three spokes, 7mph. (Assuming a mountain bike wheel). Looks cool even if not completely persistant.
- Great for safe riding at night, provides excellent side visibility.
- Playa-tested!

Safe and fun… this might be the greatest EVER!
Beats the hell out of a couple of playing cards in your spokes!

Damned straight.. I would have started cracking on the project, too, until I caught the fine print regarding maintaing persistence of vision:
Granted, I’m sure it looks cool even when you aren’t acheiving perfect POV, but a little bit of logic in the timer to account for speed differences would go a looong way…
