Glen A. Larson could be considered an American hero. He is the television producer responsible for bringing such gems as Battlestar Galactica and Knight Rider to the small screen. He has also displayed a fondness for red lights that scan back and forth, which featured prominently in the aforementioned shows. The Larson Scanner, named in his honor, is a circuit that lights LEDs in a sequence like the ones he used. Use it for your costume, bike, R/C car, case mod, or — as we did — the Cylon jack-o’-lantern.
