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???
