(...) I would add that it will take some experimenting to get the parameters correct. Pick your operating conditions (parallel outputs, or no, etc...) and then given the supply voltage and maximum current allowance, you know the coil resistance you (...)

I do notice from your picture that you have a version 1.0 RCX equipped with an AC power input jack. Have you tried running (...) (18 years ago, 15-Jan-07, to lugnet.robotics.nxt, FTX)

Hi Chris, (...) that is not quite right, there is an ATMEGA48 microcontroller insider the NXT Brick which generates the waveforms. It is connected to the main processor via an I2C-style interface. Besides that it also controls power to the NXT, (...) (18 years ago, 15-Jan-07, to lugnet.robotics.nxt)

I have written a quick-and-dirty NBC program that sends messages via BT to the PC. Then I have another quick-and-dirty Perl script on the PC that captures the messages and displays them to the screen or you can redirect to a file. I've been using it (...)
