Instructions for attaching two or more to the same wheel

by filmo on Sun Aug 19, 2012 9:47 pm

I've got the 3-spoke kit.

Didn't see guidance for how to configure these all on the same physical wheel. I'm going to assume that I should space them about 120 degrees apart???

As a side question, how do they all stay in sync to display the same image ? Obviously there's no direct communication between the devices. Does it rely on them all being in the same state (eg "standby" ) and the passing sequentially by the magnet???

120 degrees apart is ideal. But it is not critical. If your spoke count is not divisible by 3, then go with the closest you have.

That is right. The magnet synchronizes the start of the image and the timing between magnet pulses estimates the speed.
