HiJack power and bandwidth from iPhone headset port

HiJack power and bandwidth from iPhone headset port

Project HiJack is an elegant take on an old idea. Ye-Sheng Kuo, Thomas Schmid, and Prabal Dutta from the University of Michigan’s EECS Department have done the iPhone hacking world a solid by producing one of the coolest little pieces of kit to come around in a long time. In short, the device can pull several milliwatts at 3 V and communicate at 8.82 kbaud using the iPhone’s headset port.

The Processing sketch is using the java library twitter4j which handles the communication with the Twitter API.
