Weblog Racer1Awesome derby car mod – “I wanted to show you all the cool car my son Matthew and I made for his cub scouts pinewood derby. We wanted to do something entirely different and decided on mounting a very small camera to it along with an LED in the back to look like a jet engine. It was powered by a 9V battery which also served as the car’s weight. The car broadcast wirelessly to a receiver which we recorded on mini-DV. We won 7 prizes and finished 4th in the races.” [via] Link.
