  LNP under Cygwin(Windows)
 
Hi everyone, Me again.Does anyone know how I can get LNP to work under Cygwin(Windows)? Most of the documentation I've found make references to Linux. I'm planning to use LPD for communication between 2 RCXs. Has anyone tried that yet using LNP (...) (21 years ago, 7-Aug-03, to lugnet.robotics.rcx.legos, lugnet.robotics.rcx)
 
  Ball Passing between RCX Robots
 
Hello everyone, I'm currently fooling around with my Mindstorms to get two RCX robots to ball pass between them. As there are only 3 inputs on RCX, I've used 1 for ball sensing, 1 for a touch sensor(to feel for the ball) and 1 which I'm planning to (...)

  Re: light sensor question

If you look in the appendix of that document you'll find information on the light sensor (and many other things...) Magdalena (21 years ago, 31-Jul-03, to lugnet.robotics.rcx)
 
  USB2 and IR-Tower problem
 
Hi, I was just wondering if anyone here had experienced any problems using the IR-tower on a USB2 port? My university has just upgraded 20 of the pc's used for the Lego, the previous setup worked fine and the tower was attached to just a normal USB (...)

  Re: light sensor question
 
(...) A friend of mine suggests that the poor response of the sensor to the LED is because the light from the LED is a single color. Where as the light from the incandescent bulb is white light which apparently contains many if not all of the (...) (21 years ago, 29-Jul-03, to lugnet.robotics.rcx)

  Re: light sensor question
 
(...) The Analog to Digital converter of the h8/300 (the brains of the lego mindstorms) is 10 bits, so it has a range of 0-1023. I'm not sure how it converts that to the 0-100, it may do it by just dividing by 10 and rounding. If you want to see (...) (21 years ago, 24-Jul-03, to lugnet.robotics.rcx)

  Zooming in robolab, printing in RCX
 
Is there any way to zoom into the icons in robolab, they are a bit tiny and I wanted to know if I could make them look bigger so its easier to see.

  USB/Serial Converter
 
Hi, folks. I've tried to connect to my RCX 1.0 (firmware 0328) from my laptop. Since I have only a serial IR tower, it works fine on my desktop PC, but communications won't work when I use a USB/serial converter to connect it to my laptop (there (...)
