[Yvo] sent us his latest creation, this awesome POV RGB bicycle rim light build, which features a circular interweaving of common RGB LEDs that face outward along the rim as they display constantly changing animations based on the wheel’s rpm.
Like many POV wheel builds, [Yvo]’s takes advantage of a hall effect sensor and stationary magnet to determine how fast the wheels are spinning. Unlike most POV builds, however, [Yvo’s] creation doesn’t have just one or two RGB sticks clamped onto a spoke. Instead, his wheels boast several individual RGB LED modules mounted along the rim.
Each wheel has six modules, and each module contains a scratch-build LED controller (a daisy chain of 74HC595 shift registers) that fits into a custom-made 3D-printed enclosure. The enclosures mounts onto some aluminum strips along with the RGB LEDs, and the aluminum strips mount to the wheels by straddling the rim.
At speed, the lights go into POV mode to simulate headlights / brakes with white in the front and red in the back. Check out the difference these custom circular modules make when riding and when at rest in a video below.
really reminds me of this kickstarter https://www.kickstarter.com/projects/revolights/revolights-join-the-revolution
Nice build, but it seems to me that wheels become asymetrical, there should be some kind of counterweight for battery&electronics box.
Nice build.. Just don’t forget to turn em off before riding your bike when you’re in the Netherlands.
They aren’t legal in any way. And much to distracting for other people in traffic.
Vee vill adhere to zee rules mein glorius leader!! Loool.
Cool build. I also like the background music.
I see brake handles and I think cables, but I don’t see any actual brakes.
Drum brake in the axle, you can see it on the large picture on instructables
