Sometimes you need electricity to charge your batteries, but if you're limited to cardboard, duct tape and a bit of electrical components, don't wory this simple solar charger wil help you.
------------------------------------------------------------------------------------
You will need:
-Cardboard
-Duct tape
-Solar cell (3v)
-Diod's
------------------------------------------------------------------------------------
Tool's:
-scissors
-scalpel
------------------------------------------------------------------------------------

Step 1: Making a Box

Cut out a cardboard box so It can fit solar panel (6x6 and 3 centimeters deep)
You will get a box with displacement of about 108 cubic centimeters.

Step 2: Making a Circuit

Make a simple Graco's compound whit 4 diod's  http://img859.imageshack.us/img859/9834/napajanjesamo1.gif

Step 3: Final

This is It now you can charge your batterys ( 1,5 volts)
Stay safe and think smart.

    why on earth are you running a bridge rectifire on dc voltage you only need one when changing ac to dc voltage
    here you only need one diode on the + side of the solar panel so the power goes from the panel to the battery in daylight so when the panel is in dark the battery can not dump power into the panel and discharge

    ethern if the panel is 3 volt you can still safly charge a 1.2 volt battery it will just start charging in lower light conditions

    no because the forwed voltage drop is higher on the led ideal you wont a Schottky diode the forwed voltage drop is a lot lower then a normal diode
