Hello, Did you only buy the mobil unit or did you get another tower with it? The two unit could have different fequencies. The cybermasters I have both have 26650 and 26950 MHz crystals. (or something like that). Lars Gertsen - Denmark "mick (...) (23 years ago, 5-Jan-03, to lugnet.robotics)

hi there, as you may know, the RCX contains only 3 inputs + 3 outputs. and if you ever tried to build a real robot with it, you may also know that this is far from sufficient. to solve this problem, we built some extension called LEPOMUX. it uses on (...)

Hi there, I am just wondering - Snaptrax, the Spybotics tracked thing looks like it has longer rubber treads than treads included in RIS. Is it true or not? I tried to build treads with similar design and it looks like there's much more friction (...) (23 years ago, 5-Jan-03, to lugnet.robotics)
