Here is another photo of the 300 LEDs powered by the Fuji circuit.  This one I used the flash.  I forgot to post earlier.



@ Wilby:

Thanks for the diagram.  I believe your way is designed to not use the battery holder that is built to the board correct?  I did on the other board and probably will with this one also.  We are way different on where the switch goes.  I don't know enough to say which way is correct but I guess that is what experiments are for. (And smoke tests)

correct, not meant to use the original battery holder.

@ jeanna

In order to have the flash switch in the same place on camera body, the flash switch would seem to have to go where marked. Is it possible that the switch is shorting this thing to the metal trace surrounding it?
