Have you ever been outside and had your phone die? Have you ever wanted to make your own solar panels for charging a cell phone or electronics project? Now you can!
Each panel costs $1.25 in materials and provides 0 - 0.5V at 400-1000mA depending on load and lighting. The panels are linkable by magnets, and can be reconfigured on the fly to provide different voltages and currents
This is a cheap, portable device that can be used to charge your cell phone when you're camping or on a grassy knoll somewhere.
It is easy for anyone to make, with tools that you might have around the house.
