I love these DIY videos. A while back we posted on how you could recharge an electric drill nicad by zapping it with a MIG welder. Well, here’s a new spin on things. It seems you can create a hand-cranked generator out your rechargable drill and recharge any battery – even regular alkalines. Pretty cool, and this one looks easy to build out of parts you probably have around. I’m not exactly sure how practical it would be recharge more than a few batteries this way, but if you’re super cheap and need a good workout then you’ve got hours of fun ahead.
