    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!

    A bit OT but this is something that could be done really easily with a
    Microcontroller. And for basic thins like this you could try
    www.picaxe.co.uk

    BTW if you can program PICs (or AVRs etc) then just google for a blinking
    LED routine for the cheapest PIC you can find (12Fxxx) and load the free
    code to blink your leds

    Thanks for your reply.
    I've already tried that option, but since I'm needing lots of them,
    that would be expensive to make the PCB, buy the components and
    assembly them.
    What I'm really looking for is a COB like comedia have. I've tried it
    but they don't have continuous operation and with 10Hz.
    The COB is ready to run and if it has the led, it'd be better.
