AA Battery Solar Charger:

AA Battery Solar Charger: This almost trivial circuit may be used to charge a pair of AA or AAA sized cells in the sun. I have used it to keep my Palm Pilot and walkman radio running perpetually. This is an unregulated charger, proper charging is achieved by placing the unit in the sun for a known amount of Time, this Time varies according to the battery type.
