Hi.

Add me to that list. Well, to be totally honest: I have no idea of the circuit needed to get the 4 leds to work properly. If I had a circuit diagram, I could probably turn that into a prototype (hand-wired) board. But I would really prefer a clean, etched, PCB to this.

So if anyone is producing them or made a few extras, I would need two of these PCBs. Will of course cover your expenses.

cu,
Sven
