I think it's an excellent idea... I saw the barcode system being explained some years ago and I still think it can be the most accurate. One thing that's different in the system I saw was that there were no LED's used (not needed...) and it would (...) (25 years ago, 29-Mar-01, to lugnet.robotics.rcx)

Your original post mentioned "warning or alert". Are you looking for train sounds, or warning sounds? The train sounds that Sonnich is talking about is actually the puff-puff of a steam engine, and would be very difficult to duplicate with the RCX, (...)
