apologies if i offend anyone by posting this here but there isn't a good forum for canon hardware hacking so i thought i'd post it to one of the most technical boards.
i just realized that my canon a650 fits perfectly into the camera housing if i just let it press against the sides. the problem? the power jack is on the side!
solution - power the camera through the battery port.
the camera takes 4 AA batteries. most likely two sets of two in parallel to double the voltage. (i think that doubles the voltage.) the external power supply outputs 4.3v, 1.5A.
would it be a better idea to feed 3v through the battery compartment?
any other advice? i'm just taking a shot in the dark to find a solution to this problem.
