I've released a new version of NQC today (3.1r1). (URL) would be most grateful if a few non-Windows platform folks could download the source release and make sure it builds and functions correctly on your favorite platform. I *think* I fixed all the (...) (20 years ago, 15-Mar-05, to lugnet.robotics.rcx.nqc)

(...) This is just the datalog display. It indicates, in 25% increments, how full the datalog is. This indicator is totally harmless, and can be ignored. If you want to get rid of it just download and run the following program: task main() { (...) (20 years ago, 15-Mar-05, to lugnet.robotics.rcx, lugnet.robotics)

I don't work for the LEGO Company, but I felt that this announcement should be posted in the official .lego group. -Suz (URL) reposting the announcement of a special event. This conference, at the LEGO Enfield HQ, is a big deal! For those who don't (...)

(...) I couldn't call myself an expert either! In your second way of looking at it, the full voltage and full current are already multiplied to give full power for part of the time. I=(Vcc-Eb)/R Current I, Voltage Vcc, Back EMF Eb and motor (...) (20 years ago, 14-Mar-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)

Hi, (...) this means that the class files are in a newer format that Lejos cannot use, so the compiler needs a '-target 1.1' option (with Java 1.5 you may also need '-source 1.2'). It seems your Lejos version is rather old, the current ones put the (...) (20 years ago, 14-Mar-05, to lugnet.robotics.rcx.java)

Hi Mark, (...) is it really true that there is a square law for PWM? Can you explain the reason why this is so? I understand that this is true if you change the voltage (half the voltage gives half the current so a quarter of the power). But I (...)

(...) That sounds like the datalog indicator - while RIS doesn't take advantage of it (to my knowledge), the RCX can function as a datalogger - the quarter of the datalog that is being loaded flashes, while the quarters of the datalog that are (...)

I am not sure here - but could that mean that the batteries are seriously low? It would seem likely if they have been sat for a while, as even when powered down there is some residual current usage, and leakage in the RCX. Remember that when (...)

G'day, I have been using my RCX 2.0 brick recently after it has been laying idle for a period. I have noticed that there is an extra icon in the display window which is not discussed in the Lego Robotics Invention System 2.0 Constructopedia. I was (...)
