There is another thread about this that someone recently started but I didnt want to hyjack his thread and change the topic....

Whereas I, do not show the same consideration.

Actually, it was a numbers thing. Your thread had 90+ views and 3 replies, and mine only had 60+ views and 2 replies. Personally, I think using 'whore' in your thread title accounts for the 30% increase in traffic, a tactic I will learn from and implement. (Changes his own related thread title to say "Photo Cells and Lap Dances").

My thoughts on how to sense laps:

Photo Cells:
Pro: Should work for any car. They all have to break the light beam.
Con: Have to have this light thingy over the track - may not fit in with a theme for the layout.

Magnet Reed Switches:
Pro: You don't need something over the track.
Con: Maybe some cars' magnets wont trip the switch?

Dead Track:
Pro: You don't need something over the track.
Con: Mental block on purposefully created a dead spot on the track, when I don't want any dead spots on the track.

The good news is: If you are going to attempt any of the above yourself, the cost is minimal. I spent $10 at Radioshack on my photocell attempt, and have the bag here of parts ready to take back for a refund. I'll try something else next, and one way or another, get the result I need.
