How do I make a solar charger for 8 NiMH batteries?
I want to use solar power to charge batteries to use to charge electronic devices (phone, ipod,etc.), and put it in a backpack. Is there any way to modify a regular AC NiMH charger to safely charge the batteries? Or do I have to make my own? Also what do I have to do to regulate the final power coming form the batteries to charge the device safely. I know that there are instructables on this, but some contradict the others and most don't include all of the things that I need in one instructable.
Thanks in advance
