USB data killer by jamesglanville Mar 2, 2013

Description

This isn't really as dramatic as it sounds, I just wanted a cable that passed through usb power, but not the data pins. I'm using a stellaris launchpad to control a clock I made, but annoyingly if I try and develop with a second sometimes I flash the firmware over my clock's. There's probably a software way around it, but this was quick.

Another use for this: public USB chargers in airports. I'm leery of plugging my phone into them after there was a proof-of-concept malicious one at DEFCON (that pulled email credentials off your phone while it charged), but this would let you use the tasty power and not the evil data pins. Definitely making one of these for the next time I fly. :)
