This will also electrify the track, and power any other motors on it too though. If you break the connections to the (...) (23 years ago, 15-May-01, to lugnet.trains)

| | | | | | RCX motor pulsing —Steven Barile
|
| | | | Since you guys are talking about this I have a question. I've asked it before and there was no responce. Here it goes: I want to use the RCX to control a single train thru the rails by providing "pulsed" voltage to have fine control over the trains (...)

| | | | | What kind of train you to use (Lego, Trix, other) ? Although I've no experience, I have the feeling that only a Lego train could be controlled, as far as I know Trix uses AC current and for the other brands I've the feeling all specs are too low.

| | | | | I don't use the RCX but I do know know to control a motor. I would picup the power and "pulse" the motor will e.g. 400 Hz, but pulse-wide-modulated. The idea is that the motor gets full power but not all the time meaning thar it has full strenght (...) (23 years ago, 19-May-01, to lugnet.trains, lugnet.robotics)

The question is how to control the speed of the train under a finer ganularity then just the native power levels. snip ...this comment has promise!
