Hi; I just thought I'd share my success in using Pc Lap Counter along with two web cams and Zone Trigger, on my HO scale track. HO can be a challenge due to the speed of the cars relative to their size. I had the same problem with my former photo-cell detection system which I never did completely overcome, but with Pc Lap Counter, not only have I got it working great, now we race with refueling pit stops too!
Visit my site to see my track and the web cam setup.

If anyone else has been successful with HO scale tracks feel free to tell me about it.
Thanks,
Graham
