I have seen DIY Segways before. Hey, if you want a Segway, but don't want to pay their price... and you are smart enough to make one yourself, go for it! Which is exactly what these guys in England did. Except, they made theirs a UniSegway. I just invented that term - what do you think? Watch the video and see how it works. Oh yeah, if you have any ideas of doing this yourself, you'll need to learn how to write code for the controller that makes it all work, or find someone who is willing to do it for you.
