Step 11: Enjoy
Now you're done. Enjoy the fact that you're being very green and clean.
Also, before someone chimes in... yes I do know batteries are not entirely green. If you want to be super green you should use some super capacitors for this project. They last forever, are super green, but are also quite expensive.
What I like about this project is that it's simple and handy. It makes for a nice gift.
If you need any parts you can always get them from my website, BrownDogGadgets.com. All the money I make goes to doggy treats and more projects.
Thanks for reading! *** Update: I've since retired this kit. It's not held up over time very well. I've done an updated version called Solar USB Kit 2.0 and a more rugged version called Lithium Heavy Duty 2.0. If you're looking for something pre made, especially for camping or emergencies, you should try out one of our Folding USB Solar Cells. They're inexpensive and much much more powerful than what you'll find here.
