Backpack Solar Charger Kit

I think this is so friggin cool. My co-worker just rigged a solar charger to his backpack to charge his mobile devices on the commute!

He got the kit and instructions here: http://learn.adafruit.com/solar-charging-handbag

I got to make one. My understanding of solar energy and electronics is suuuuch weak.

DIY HAND-CRANK iPHONE CHARGER FROM SCRAP COMPUTER PARTS

Last month, we told you about a fun contest from Sparkfun, all about reusing electronic components:

Build us something, anything! It can be a working piece of circuitry, or a wonderful piece of art, or both! It should be made out of at least 75% reused parts (though we encourage 100%!).

Well, there’s a winner! It’s a DIY hand-crank iPhone charger:

The power source is an AC turntable motor salvaged from a broken microwave. The project enclosure is a reused cardboard shipping tube. And many of the electronic components, such as a USB receptacle, were scrapped from old computer boards.

Read more about it — and other impressive entries in the contest — here.
