Small battry will fit, cost 0.50-1 Euro and will give up to 70 mA (with two) > Power consumption during operating max 35 mA Wait the controller and the rest will also consume some power... the Chipsbank CBM2080 will consume up to 29,5 mA with USB 1.1 so with a battery hack the USB memory device would be usabel for reading/writing for about 1h - only neccessary on the road without an USB powered swith - so that would be enought for some weeks/month.... What will be the advantage to use this hack instead of using another microSD card? -you can borrow this usb memory drive to somebody who have no card reader -you can do backups of important data on the road without removing the battery (and reboot your Neo) -the hack is cheap and easy rob _______________________________________________ OpenMoko community mailing list community@lists.openmoko.org https://lists.openmoko.org/mailman/listinfo/community
