Be ABSOLUTELY SURE you have the Polarity of both ends (the battery AND the plug onto the camera right - there is NO reverse polarity protection on the camera board and it WILL fry. Triple check, then check again. really.
Anyway, you can power the camera board from most any source of 6 ro 15 volts DC that can supply 200 mAmps. the 7.2 volt backup battery - or an R/C battery - is just fine.

I know to be very careful - I think we're going to have the NiCad battery one one end and a regular 3-pin PWM connector on the other. I'm guessing it means that if we plug it in backwards nothing will really happen because the 3rd pin (where the +7.2V is going to) is disconnected.
I found this:
http://www.cs.cmu.edu/~cmucam2/CMUcam2_manual.pdf which says the same thing, that any input 6-15 volts can be used. By the looks of it, these CMUCam2 boards are a lot different than the FIRST ones. However, are they (for the most part) electrically identical?
Thanks
