Pinewood Derby test track timer
I would like to have a timer for testing changes to pinewood derby cars. Need to have a trigger a the top of the track and one at the finish line. Could be stand alone with time display or output to a PC for capture of each run. Better still would be a second set of trips to give a split time 1/2 way down the track.
Since this will be used for testing, it only needs to measure time on one track. Simple and cheap.
