The second idea came to me yesterday as I was reading
this thread. I wondered if
instead of building a contraption involving magnets and a light sensor, could
I instead simply induce current in a wire as a LEGO train and its coupling
magnets passed above it? That would tell the RCX the train passed that point.

A much simpler “contraption” that you can build is discussed in
this LUGNET message. The basic
idea is that you place a reed switch in the railbed and it will sense the
magnetic couplers between the cars of passing trains. I have been using this
technique for a few years now and it works very reliably. Hope this helps.
I also recently offered these sensors
for sale, but due to the complete lack of interest so far, I do not plan to
produce them in any large quantities. Once my existing stock is depleted,
you’ll have to build your own.

| (...) Thanks for the links. I would really like to use such a sensor, but I'm a LEGO purist. Maybe that's irrational, but it pains me to see things like servo motors and ugly exposed circuit boards attached to LEGO. Even if a device is hidden inside (...)

| I'd like to share two thoughts with you all. They involve the RCX and doing things with it that I'm sure the designers never intended (or thought possible). Oh, if you're reading this in the .trains newsgroup, you can skip over the first thought (...) (21 years ago, 1-Sep-03, to lugnet.robotics, lugnet.trains, FTX)
