Hand Recharged iPod Shuffle

Posted by Zonk on from the ye-olde-ipod-shuffle dept.

randomErr writes "In one for the first article on the new O'Reilly MAKE magizine we see how to recharge your iPod with a crank. The "Torronesque" project was based on the idea of coming up with a project and buiding it even if it has no immediate purpose. Imagine getting a little power charge every time you press a key or open your phone or laptop."

    It was patented in 1999 (the keyboard idea). here.

      Just because it was patented doesn't mean it's a good idea of course; I believe the amount of power that can be generated by this method is too small to be of much use, even at theoretical 100% efficient conversion. Instead of allocating extra space, weight, and manufacturing cost for this complex charger system, simply including a bigger battery will improve battery life more. There is some interesting discussion along these lines in the original Slashdot story about the patent (also from '99).

  2. Heard of it already by deutschemonte · · Score: 5, Informative

    I heard of this like 2 years ago (or more) for cell phones. They had a charger that you could crank by hand, a mini solar charger you could put on your dashboard or roof of your car, and a fan that sat on the outside of your car. Admittedly I don't remember the company, but this is really old news.
