Solar cells are getting so easy to come by that making your own gadget charger is far more interesting than buying one of the many that are coming onto the market now. If you're looking for a weekend project, we dig this one. This Instructable takes a MightyMintyBoost kit, used for creating backup battery packs in Altoid tins, and adds a solar cell for sun charging. What is extra cool about this hack is that you don't have to stick with the one solar cell. The creator has made it so you can take off the small cell, put the battery back in another place like a backpack, and plug in a larger solar cell attached to your backpack. The cell is simply attached to the tin via Velcro.
