No problem. Rectifier and a high quality step down switched regulator will easily provide the 5V/0.5A USB-power to operate/charge the NEO. You might even get off with a low drop linear regulator (78L05). A 25V/2W Zener (or similar overvoltage protection) for Vin might be a good idea. j _______________________________________________ OpenMoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
