These are my first hacks and first one Sony W200 and shutter works and internal battery okay, running wires from + and - to external 3 cell pack, get error " for use compatible battery only" powers up then shut down.
Camera 2, is Panasonic DMC-FS7 with almost same problem, powers up, error, then shuts down, using battery + and - from inside camera, to external out.
Camera 3, Olympus VG-165, with External battery wires again and wont even power up.
All these cameras work fine with internal batterys, power up hack and shutter. Could someone please help me, really do not know whats wrong.
