Worse yet, when the power runs low the RCX is likely to corrupt the firmware unless you put in code to monitor the battery level (something I'd suggest if you go this route).

(...) For future, LEGO's educational division does sell 3m LEGO wires. (...) A 1.0 RCX that allows you to power the setup from an outlet is ideal for this.

(...) I wanted the layout to be pure LEGO, but if I run out of time building this I'll break down and use non-LEGO wire and my original setup. (...) I wasn't worried about hiding the RCX, but I have seen the batteries run down very quickly. In the (...) (19 years ago, 28-Nov-05, to lugnet.robotics.rcx.nqc, FTX)

(...) That was basically my plan if I couldn't get the light sensors to work reliably. Based on Brian's post I might go back to my original design, though. (19 years ago, 28-Nov-05, to lugnet.robotics.rcx.nqc, FTX)

(...) Speaker wire and small alligator clips will make a dandy solution for extending the basic wires - after all, you really only need one very long wire here (to the "remote station"), and yoiu have a working set-up.

(...) If the rcx is on the train why not mount touch sensors on the underside looking down. You could then attach small ramps to the track which would trigger the sensor. If you put the sensors on a spring loaded mounting you shouldn't have problems (...) (19 years ago, 28-Nov-05, to lugnet.robotics.rcx.nqc, FTX)

For Christmas I'm setting up a LEGO train on top of a narrow wall, so it has to operate like a shuttle -- stop at each end and reverse motor direction. My first attempt had a train regulator attached to a polarity switch, with the switch being (...)

(...) That would require extensive redesign, as the 4095 unit also contains the motors in a compact unit... Philo BTW: imho 4095 is not worth buying (main unit is close to useless) unless you get it at a very low price! (19 years ago, 25-Nov-05, to lugnet.robotics.rcx.legos)
