I made a RCX Controlled Mobile De-coupler base on http://members.nbci.com/jrickclark/ak-decoupler.html
When train coming, this Mobile De-coupler will find the space between cars of
train, then de-couple the magnet. I will use it to design a marshaling station.
I will show you photos next week. It used 4 light sensors, 2 touch sensors, 2
motors and 1 RCX/Scout.
You also can check back at my homepage http://legochina.virtualave.net/MOCs/RCXTrains.html next week.
I've just completed your version of the decoupler device, and I must say that it's excellent! 8-wide train builders may want to modify this due to clearance reasons though.-Harvey (23 years ago, 5-Jul-01, to lugnet.trains)
