| Not much right now. I forgot to post a picture of the front of the boxcar. It has clear windows to allow the RCX to receive IR commands. I have used the Lego remote to control the train. Eventually, the RCX will be the main power for the train and (...) (24 years ago, 8-Feb-01, to lugnet.trains)

| (...) Hmm. I tried powering my train motor off a battery box, connecting to the electric studs on the top, and it belted around the track. I guess you're using slow speed mode from the RCX? I'd be a bit worried about how much power the RCX can put (...) (24 years ago, 9-Feb-01, to lugnet.trains)

| If I run my trains at 3v, then two Lego Solar Panels can provide ~3v. Looks like I have another project after this one. As for powering the RCX through the train track, I had not thought about having to run the controller full tilt to power the RCX. (...) (24 years ago, 9-Feb-01, to lugnet.trains)

| (...) You're forgetting something important - as the load on the motor increases (e.g. pulling more weight), the current it draws will increase { Power (W) = Voltage (V) x Current (A) }. You only regulate the voltage with the controller, not the (...) (24 years ago, 10-Feb-01, to lugnet.trains)
