Sparks,
 

I like your idea but I am clueless as to how to go about doing this on a breadboard.  I could probably figure out how to set up the 555 chip but would I need a 555 clock for each of the 8 Infred LED emmitters or do I drive them all with the same 555 hz signal?

 

If this can be done, then how do I wire up the 8 detectors such that when the infared beam is broken/blocked, I can light a remote LED to indicate the blocked section of track?
