>>1460852You can probably just use something really low key to transfer photos to. Like a couple big USB sticks on a Raspberry Pi. At most, they use like 12watts. you can get a remote & a tiny keyboard or regular sized one for them and a little screen that attaches to the top. So, a battery and solar panel will work even better. You can even slap one on a keyboard like this person did.
