Rechargable batteries are a great invention, but if you dont have an outlet nearby to charge them, they are usless. So I designed a solar powered battery charger, which allows you enough power to charge a single AA battery wherever the sun may shine.
I chose to do this project in two steps:
First I set it up to test that I generated the needed voltage (3-7).
Then I set it up to finalize, by using wire instead of alligator clips, this made it both look better and was easier to work with (8-10)
People have told me that 1 volt is not enough to charge a battery. I looked a rechargable battery and it said "charge: 1-2 volts." I would also like to add that I switched the tester to 2.5 volts and the meter moved to 50%. This tells me I do not only generate 1 volt, but 1.25 volts give or take...
Step 1: Materials
Here is a list of the Materials you will need to recreate the Battery charger I have made,
-Light socket attached to wood (with outlet plug)
-100 watt bulb
-Hot glue gun
-Two solar panels
-Three alligator clips
-Rechargeable AA battery
Once you gather your equipment, I suggest plugging in your Hot Glue Gun, so it is available to you once needed (Step 4)
