At the NMRA national train show in Portland OR., I saw a really innovative display. The man had built a TT scale switching layout in a guitar case. He had true remote controlled couplers on some of his locos and cars. He had mounted a tiny servo dead center in the floor of a boxcar. This servo operated one of two levers going to the couplers at each end of the car.
The levers would open the knuckle of a Kadee coupler on the command of a function output from a DCC decoder. On the Loco, he had used a tiny motor originally designed to act as the vibrate device in a pager.
After all that explanation, here are my questions. If the man who made the guitar case layout is on this forum, please answer. If anyone else knows the answers feel free to jump in. Thanks.
1) How did you remove the weight from the pager motor's shaft? I managed to cut one off with a Dremel tool, but it was a difficult job.
2) What brand, size, model#, Etc. servo would you recommend? I work in N scale so the smaller the better.
3) Do the servos require any programming, or additional electronics, beyond setting up the function key on the DCC system?
Hope to hear back from you;
