I normally post on more weighty issues than turning a hand-cranked flashlight into a battery charger for your portable electronic devices, but I somehow came across this video yesterday over at Carbon Planet and thought I'd pass it along—in case you've got a spare flashlight, some electrical tape, an old laptop battery and some basic skills with electronics.

If you want something a bit more, um, polished looking, there are plenty of hand-cranked chargers out there. And for our more experienced DIYers this may be old hat, but budding tinkerers take note.
