(...) It seems like MacNQC can be used to download a new firmware on the RCX: (URL) you didn't, you should give it a try. I also had problems downloading firmwares to the RCX through the USB tower with many utilities. Only NQC did it right. Please (...) (20 years ago, 23-Jul-04, to lugnet.robotics.rcx)

Hi Andreas, (...) this is the pwoer supply for active sensors (light and rotation). It is interrupted briefly every 3ms to sample the value of the sensor. (...) It is done by the microcontroller, every 3ms the OCIA interrupt routine turns off the (...) (20 years ago, 21-Jul-04, to lugnet.robotics.rcx)

(...) Hi Andreas, Sensor inputs can be configured two ways: 1. Passive - sensor does not need power to operate 2. Active - sensor needs power to operate Active sensor ports put out aproximately 7V most of the time, and drop the voltage (every 3ms?) (...) (20 years ago, 21-Jul-04, to lugnet.robotics.rcx)

Hi, I'm interested in the electronical function of the three sensor inputs of the RCX. I took an osilloscope and measured the voltage of the ports. So I got to know that a rectangular signal is put on the sensor ports when they are activated by (...) (20 years ago, 21-Jul-04, to lugnet.robotics.rcx)

| | BrickOS on Mac OS X (restarted ?)
|
|
11 months ago, there was a thread in this newsgroup dealing with the implementation of BrickOS on Mac OS X. I was just wondering whether the situation had changed since then. I've downloaded M. Zapp's port of the GCC cross-compiler and tools, have (...) (20 years ago, 21-Jul-04, to lugnet.robotics.rcx)

NGLTC (and other train club) members have been getting creative with their mindstorms. 1) Rail Racers! 2) Lewis Valentine has made a working train drawbridge on the NGLTC layout. It's taken him a lot of tinkering, but it works very well! 3) Street (...) (20 years ago, 19-Jul-04, to lugnet.robotics.rcx)

Please pardon the interruption, as this is probably a bit off-topic, and is more a distraction than a contribution at this point. ;-) I've been looking in the various LUGNET forums, hoping to find a link to a good page of clues for using the RCX in (...)

| | Re: Light Sensor question

(...) Sam, By default programming when you configure a sensor input to be a light sensor, it gives you back readings in the 0-100 range (i.e. percentage of the maximum possible reading). To get better resolution (which I expect you might want), you (...) (20 years ago, 15-Jul-04, to lugnet.robotics.rcx)
