recharging the battery in a polaroid type600 film pack
Anybody know how to recharge the 6v polapulse battery in a polaroid 600 film pack? I'm trying to rig the whole camera up to a dslr body (essentially replace the "film capture" with digital) and fire the shutter on the 600 camera. Apparently, you can't fire the shutter without juice, and from what I understand, the 600 film battery only holds enough juice to fire 10 frames, the length of one film pack.
Can anyone offer any suggestions? Maybe rigging up 6v worth of juice and connecting that to the camera itself?
