Nokia announces bike-powered phone charger…
The bike charger relies on the well-tested and durable bottle-dynamo to convert your pedaling into power, and the phone is held to the handlebars with a big rubber-band. In between is a box of circuitry to give a nice smooth current to any device equipped with a 2mm jack. The charger will first be available in Kenya for around 15 euro ($18) and will go on sale worldwide by the end of this year.
You can make your own now, Mark Hoekstra of Geektechniques who passed away in late 2008 has a great article in MAKE 11.
