I am trying to design an extremely simple circuit that uses a solar panel to Charge AA batteries, which then power's electronics over USB.
Here are the materials I have so far.
Solar Panel: 6V 830mA (Actual max seems ~7V) Amazon.com: New 6V,830mA Portable Travelling Solar Charger for Cell Phone w/ USB charging cable,GPS,DC,MP3/4: Home Improvement
Zener Diodes: 12V 1N4742A 12V Zener Diode - RadioShack.com
5V Regulator: +5V Fixed-Voltage Regulator 7805 - RadioShack.com
I also have:
7AA Batteries each ~1.85V-1V Rated 2500mA each
AA battery holder
Small breadboard
Project box
Simple sliding switch
Notes: USB is 500mA-1A at 5V.
Solar Panel-->Zener>--AA-->5V Regulator>-->Zener>--USB
Is this circuit possible with the above materials, even if the materials above are not ideal?
