im looking to build a usb charger for my android g1. i just have a question about the pinouts on a usb charger. ive come across a couple schematics that are quite similar. my question is, can i just use pins 1 and 4 as in this schematic: http://www.instructables.com/id/E1G1XM4ST4EP287KWC/
or do i need the extra resistors on pins 2 and 3 as in this schematic: http://www.ladyada.net/images/mintyboost/mintyboostv2sch.png
an explaination would be awesome! thank you in advance! -joe
