Roll Your Own Solar Gadget Charger with Spare Parts

There are plenty of solar-powered device chargers out there, but you can save a few bucks (and have some fun), but hacking together your own.

Instructables user ASCAS built a multi-device charger for less than $20, though the solar panel they used seems to be hard to find. If you can find a similar model though, the rest of the project is pretty easy. In essence, you're just hooking up the solar panel to a USB power bank, and mounting that to the back of the panel. However, if your solar panel runs at over 5V, you'll want to hook up a regulator to avoid damaging the external battery over time. The source link will show you how to do that, and more.
