That's it. Most of the people I talked to about it (...) (24 years ago, 5-Dec-00, to lugnet.trains, lugnet.robotics)

(...) Is there a photo that clearly shows the sensor in a fairly tight closeup so that it can be judged how obtrusive/invisible it is? I skimmed through many of the photos posted by you, Dave, and Tim but did not see one, although I may have missed (...) (24 years ago, 5-Dec-00, to lugnet.trains, lugnet.robotics)

(...) I might just add that while this was a bit over my head it work extremely well and the sensor itself was very small and unobtrusive. It was a non-LEGO solution but I loved it and recommend it. I think with some reworking it may even be (...) (24 years ago, 5-Dec-00, to lugnet.trains, lugnet.robotics)

(...) I used a touch sensor that slightly elevated the track, detecting the mass of train cars; it was coupled to a scout in a switch-house, and the thing would just toggle a point whenever a train went by. 100% reliable, but ... kinda ugly, and (...) (24 years ago, 5-Dec-00, to lugnet.robotics)
