Hi, well some weeks ago I promised that I'd begin a project of developing a Mech incorporating the RCX unit, some motors and sensors. Here is my very first attempt at a minifig scale Mech: (URL) RCX is programmed using MacNQC and at this stage only (...)

I use 0.2.5 in windows (djgpp), and can't get by without using the slow download option (-s). If you have lighting problems, perhaps flipping the little switch on the IR tower will help.
