COB PCB with blinking led

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!

10 Hz is quite fast. Why so critical?

10Hz is to pretend to be a candle light. I've tried other frequencies, but this is th better. Of course when we say 10Hz, 9 or 11 is almost the same thing :)

Ah yes. I guess a slightly random flickering would be even better.

Try using a PIC micro in a SOT23 package perhaps...
