Calibration timing for Bike wheel

Post by sirvanderhar »

I've been tossing between two different products currently and trying to figure out how each work in totality before deciding.
https://learn.adafruit.com/bike-wheel-p ... y/overview looks really neat and able to produce an arrangement of colors, however I can't see how it "times" for the rotations. I don't see any Hall effect sensor or something of the likes. Whereas the SpokePOV https://www.adafruit.com/products/19 has a magnet that helps calibrate the image for the correct speed.
I would like something to create a single whole image that surrounds the entire wheel.

The Bike Wheel POV project does not have any way to sync the image to the wheel rotation. It would not be hard to add a hall sensor to the circuit. But you would need to modify the code also to sync your image to that position.
