This is a very simple instructable. Really, it's more of an informable than instructable since it's pretty self-explanatory. I know there have been many other solar battery chargers, but this one was already made and sitting under my nose.
I posted this instructable the day I made it, so the jury is still out on how well it will actually work. I'm hoping for at least "kinda works, eventually."
Get cheap solar light.
Remove LED light from circuit (cutting it works fine).
Use existing rechargeable battery in system, or modify AA battery holder to hold AAA battery.

Step 1: The Backstory
This project started last Christmas when I found a pack of 6 solar powered LED Luminaries at Ollies (a discount close-out store similar to Big Lots, no telling what they might have, but it's gonna be cheap!) for $6. Yes, they were $1 each. When I opened them up, I found they were a solar panel connected to a rechargeable AA battery and a flickering LED. I was thinking about using them for the sun jar project and away into the garage they went.
A few months went by and I bought some cheap mp3 players for myself and the kids (also at Ollie's). Under $10 each, so no bells or whistle and they work fine. However, they run on AAA batteries. Regular AAA . Batteries get expensive fast, so I figured a rechargeable battery would be the way to go. Even better would be a solar powered recharger. Off to the garage to find the materials.
Yeah, I'm a cheapskate. In fact, I'm so cheap I didn't even put a picture on this step!
