Assuming you're from Germany due to your name and mail provider ( ;) ), the computer magazine c't had an interesting workshop-article explaining how to build a voltage converter with rechargable battery to power devices via usb with the hub generator of a bike. The Article can be found here: http://www.heise.de/kiosk/archiv/ct/2007/23/190_kiosk (alas, not for free, they want 60 cents for it - alternatively, you can ask someone with a c't subscription for the article) They also had a multi-parted workshop in their TV show, a link to the archives can be found here: http://www.heise.de/newsticker/c-t-magazin-tv-Sommerprojekt-Multimedia-Fahrrad--/meldung/110428 hth, Konstantin _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
