Make " This looks intriguing, the Paragon, an Arduino motor controller designed to be robust enough even to control an electric car, evidently designed to run a Power Racing Series car. The maker, Alex McLees, is a founding member of Madison, WI hackerspace Sector 67. [via PPPRS]"
At first glance I thought that this was not going to be of nay interest to me, but I am starting to get intrigued by the idea of making a device somewhat similar to a Segway, and this could be ideal. Unfortunately it only seems to be available as a commercial product and not something you can make yourself, and I can't see any prices.
Mind you it might have been popular with people building contestants for "Robot Wars"
