(...) Are you using the NXT on batteries alone, or using the Li-ion battery pack so you can plug the NXT into a wall for more consistant power? (...) As others have noted, this has worked well with the RCX. It's essentially how the GBC trains are (...) (17 years ago, 17-Oct-07, to lugnet.robotics, lugnet.org.us.ulug)

(...) I'm not sure if there's a better way, and I haven't tried it with an NXT, but I've had good luck with option 2 using an RCX. I isolated the track by putting a bit of clear tape over the ends that connect to the other track sections. -Elroy (17 years ago, 17-Oct-07, to lugnet.robotics, lugnet.org.us.ulug)

To all, I would like to find a way (simple way that is) to power our LTC 9v trains using both the standard LEGO 9v train modulator and the NXT. We have attempted the following: 1- Power the train simply using the NXT and the converter cables. Too (...) (17 years ago, 17-Oct-07, to lugnet.robotics, lugnet.org.us.ulug)

Hi, Has anyone tried using the standard NXT Ultrasonic sensor calibration settings? I've been doing a little work on the leJOS i2c interface and although I can read both the factory default values and the current settings I do not seem to be able to (...)

Hi T.C. (...) aha. I just programmed some startup and interrupt wrapper code (the rest is C), so I didn't get into the higher reaches of macros etc. Jürgen (17 years ago, 16-Oct-07, to lugnet.robotics.nxt.nxthacking)

Hi Juergen, Thanks for replying. (...) Thanks for the info. My goal is to run and debug ARM assembly language programs executing in RAM.

Hi T.C., (...) I have an AT91SAM7S-EK here, it has 4 LEDs and 4 touch buttons. It should also be fairly easy to write a driver for one of the serial ports (polling would suffice for a start).
