Ok, here’s my dilemma: I have a Compaq Ipaq 3835, RCX 1.5, Lego remote, and PDAwin learning remote control on Ipaq, and VitoTechnology o-Scope software (IR scope on the Ipaq). I had both pieces of software learn the “beep” command from the Lego (...) (22 years ago, 5-Nov-03, to lugnet.robotics)

Hi A while ago I looked at using IC for writing programs. At the time there were 2 major turnoffs. There was no support for rotation sensors and you needed to own one of the serial infrared towers. It was easy to install and it had its own firmware. (...) (22 years ago, 5-Nov-03, to lugnet.robotics.rcx, lugnet.robotics.rcx.legos, lugnet.robotics.rcx.java)

I am fairly new to Lego Mindstorms so forgive me if I end up beating a dead horse. I have a RIS 2.0 kit which, as you all know, comes with the USB tower. I plan on using MacNQC to code. Is it possible to do everything (code and transmit finished (...) (22 years ago, 5-Nov-03, to lugnet.robotics)
