I love this tutorial on how to make a solar powered bag so that you can recharge all your various devices during the day. Very handy for those out and about people who also forget to charge their phone or music device. Although my vote would be to NOt use one of those ugly-ass bags covered in logos…
This tutorial is by Solar DJ Mark Farina who, I think, can also be reached for commisions.
