This project is awesome, and the video (posted below) is also great. It’s like your suburban handyman neighbor is hacking solar technology at a rave.
Plus, this is a truly useful idea. It is ridiculously easy to make a solar USB charger out of the solar cells found in those ubiquitous garden lights. The charger will power your iPod, phone and any other small device. It provided this guy with enough power to charge and run his phone, and it’s safe to carry in your pocket.
Cost: $10, probably. All you need is access to a soldering iron and a thrift store.
