Canon USB Battery-Dummy

a battery dummy to replace a NB-11L battery pack. this allows the camera to be operated from a usb-phone charger - useful when using the camera with CHDK for longer photo-sessions :-)

wiring and idea is based upon this instructable: http://www.instructables.com/id/USB-Powered-Camera-PowerShot-Battery-Hack/?ALLSTEPS

Note:
- a pc-usb port might not work, since it supplys only 500mA max, which might not be enough for your camera.
- not every usb-phone charger might work, had one with an output voltage lower than 5v which was to little for the camera to actuate the lens-motors :P
