Camera is NiMh intended, as most digital cameras today are. Mind you, 
I expect many are going lithium these days.

Thanks for the link.

Now to go rummaging for a 10W, 10 ohm resistor ...

OH NO - NOT RESISTOR COLOUR CODES ... it's been ... decades.

BBROYGBVGW ... hmmm, the mnemonic I learned isn't ... politically 
correct these days.

White White Black Brown Silver?
