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)

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)

I dont think the joystick is the problem since I have the same problem with inputs from keyboard or mouse, but (...)
