Solar cell charger
This is a solar cell phone charger i made from an old solar walkway light. Just the solar cell, a small coil of magnet wire, a transistor, and a blocking diode was all it took to make. Works well! I will gladly help anyone who wants to make one themselves. Just ask me if you need help.! This can also charge many other USB devices!

haha brilliant
An idea I found on YouTube. Pretty cool, thanks for commenting.
Reminds me of the sort of thing I would expect to find on the Crazy Russian Hacker's youtube channel. :)
