At this point I don't have the sensor hooked to an RCX due to the fact that Santa hasn't brought me one yet (hint hint Santa). I currently have the sensor hooked into a Crestron Control system ((URL) The sensor is hooked to a digital I/O port that (...) (24 years ago, 5-Dec-00, to lugnet.trains, lugnet.robotics)

(...) Well I can think of a couple reasons why we went with 4 wide tables (40.25"x40.25"). 1. It was more economical. If we were to do 3bp x 6bp you only get one table out of a 4'x8' sheet. This way you get 2 tables per sheet. 2. We liked the (...) (24 years ago, 5-Dec-00, to lugnet.general, lugnet.org.us.nelug, lugnet.trains, lugnet.loc.us.ma)

(...) I hope youre right. I would like to see more kind of points, and a return to the first 9v train models (and some 12V models where great too !). I hate those new models (4560/4561 & 4559).

Chris, Another great little sensor for train detection, via Radio Shack, is the little photo sensors they sell. I put them inside of a 2x4 technic plate and then snap them face up on the track. This way they use the omni light from the room as the (...) (24 years ago, 5-Dec-00, to lugnet.trains, lugnet.robotics)

Chris If I understand correctly you can add a series resister to each reed switch using the formula r=2^n*R. Where n is the number of each switch (1,2,3...) and R is some resistence value that is friendly to the RCX. This way you can add several (...)
