I have not, but many thanks for the DIY link.
Very interesting PCB, even cut it is still too big for our wheels.
A resized board and smaller LEDs (guess the guy is using 5 mm LEDs) would work, I think…
For anyone looking, I bought a set of Rimfires and they absolutely will NOT fit on 18" rims!
The battery compartments make them too fat to fit between the spokes. I was going to get creative and rip them apart, but it was too much effort for me. The actual working portions are tiny! If one could fashion new battery compartments, was comfortable re-soldering some wiring on the circuit boards and waterproofing the boards, it could be done. I couldn’t see myself using them more than 3 months out of the year, so I gave them away.
Valve stem lights, here I come! Not the greatest, but cheap and better than nothing.
