NaDrew writes "The Wall Street Journal has an interesting piece called "So Your Roomba Vacuums ... Does It Also Take Pictures?" (No reg. req.), profiling a couple of hardware hackers. Phillip Torrone has modified a laptop-brained robot to follow his Segway, which he is modifying to follow a pink ball. He's also modded his Roomba with a built-in Webcam. The article goes into a bit of the history of hardware hacking, from the CueCat to Andrew 'Bunnie' Huang's Xbox hacks."
