An anonymous reader writes "One of the zany hacker-makers here at MIT just finished this DIY Segway project. Difference from the others: It's all analog. The controller is built without a microprocessor or even digital logic. It does use a gyroscope like the real Segway. The functionality looks fairly basic but the fact that the controller works at all is amazing.
The guy has a ton of other projects on his site too. Definitely worth a read for people who enjoy building things."Link to Original Source
