a lap timer and counter for slot cars
. For us it’s always hardest to come up with the idea of what to build and we think he found a great one here.
Each time a car passes the finish line of the track it trips a reed switch that was hot glued to the underside o... | 4 | 4 | [

] | [Giorgos Lazaridis’] most recent project was to
