With the announcement of the 555 timer contest, it appears we have a contender for the winning prize. "Superangryguy" has made a balancing robot, Segway like, with the aid of a 555 timer. The best part, he shows how you can build one too. I would get all the schematics right away. I am sure some underhanded people are rushing to make a toy our of this.
Good luck SAG!
