Sweet mousetrap racer! Thing mustve flown... too bad you didnt have a cam.
Reminds me of when I built an autonomous vehicle for my 7th grade science fair from scratch... my first robot ever and it still won FIRST place in my school as well as the state regional for my division in engineering...
And two years before that in 5th grade the shower-temperature-monitoring device that told you if your shower was hot enough and warned you with a loud beeper if it was getting too hot... that one took FIRST at my school then third in the 6th grade engineering division (yeah a year above me)...
Anyhow, yeah, never go against robotics kids in engineering/physics/science classes.
