The easiest and cheapest I have ever seen, used a LARGE calculator,
a micro switch for each lane, and some fairly simple wire.
You will need some soft sense micro switches, and wire each lane to the
inside of the calculator. The switch must be setup on each lane to
make contact with the "nose" of the car etc. We had discussed wheel
contacts to allow for car nose variation, but stayed with the "nose"
wire lane 1 to button 1 - lane 2 to button 2 etc.
The order that the lanes display, is the order of finish. It will
not display any ties.
However, if you want total elapsed times, and programs to display
standings, there are a number of PC programs at various web sites.
The cost of that equipment was beyond our pack budget, and we found
the order of finish was good enough.
