(...) 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)

(...) 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)

(...) 1) take a section of straight track. 2) take a light gray 2x4 plate and place it so that it spans the 2-stud gap between two of the ties. 3) imagine a very thin silver piece lying on that. That's it. Most of the people I talked to about it (...) (24 years ago, 5-Dec-00, to lugnet.trains, lugnet.robotics)

(...) I know I didn't get a close up because my camera stinks for close ups. I think Chris may have gotten some but he hasn't uploaded his pic's just yet. If we don't have one now, we are having a meeting in a couple weeks and we will make sure to (...) (24 years ago, 5-Dec-00, to lugnet.trains, lugnet.robotics, lugnet.org.us.nelug)

(...) I just looked through my pictures and I was surprised to find that I don't have any that show the sensor. I will snap a few close-ups tonight... I also like the idea of doing a more formal write-up with pictures, schematics, and part sources. (...) (24 years ago, 5-Dec-00, to lugnet.trains, lugnet.robotics, lugnet.org.us.nelug)

(...) I took a few close-ups of the sensor last night, and uploaded them to BrickShelf. Check out: (URL) first picture is the sensor itself with a few "common" objects nearby for scale. The second picture is my reproduction of the exact setup that (...) (24 years ago, 6-Dec-00, to lugnet.trains, lugnet.robotics, lugnet.org.us.nelug)

(...) Chris, I was just wondering if there was a decline in performance in the enclosure as opposed to outside of it. The enclosure looks great! Eric Kingsley The New England LEGO Users Group (URL) (24 years ago, 6-Dec-00, to lugnet.trains, lugnet.robotics, lugnet.org.us.nelug)

(...) No, there is no apparent decline in the sensitivity of the reed switch when it is encased in LEGO. In fact, the switch that I bought from Radio Shack was originally enclosed in a plastic housing, which I removed to reduce the bulk of the (...)
