I'm looking for a COB(chip on board) PCB with a blinking led. This can be found in toys and electronic candles. I need to find manufacturers or resellers which I think are mainly in China. If the cob+led isn't available, I'll also be interested just in the cob. I've already seen some kits from kitsrus and some cob from Comedia but they don't do what I need: 10Hz, 1/4 duty-cycle.
I'd appreciate any help you could give me, even if there are other newsgroups that I could ask for.
Thanks in advance!
