How to make a model slot car drag strip timer? Answered
I want to build a slot car model drag strip in HO scale with all the bells and whistles. I wan the electronics to run a Christmas tree starting light, catch red light disqualifications, determine who wins, measures and reports on a 'billboard' the reaction time, elapsed time and top speed. I can do all the other stuff like making and wiring power tot he track, make competitor starting buttons, adjust track voltage to power the various classes of car but I can't do the electronic stuff. Can anyone help?
