I am trying to build a synchrodrive. For this I require 4 turntables (part no.9876). If I live in the UK, what would be the quickest way of obtaining these pieces? Thanks for your time, Robin (25 years ago, 16-Jan-01, to lugnet.robotics)

Well, you were lucky. I contacted Lego at the number you gave me and tried to see if they would send me an upgrade as well. They will, but for $25 US ($40 Cdn). Bummer. It's the second time this week. Matthias Jetleb VA3-MWJ (25 years ago, 16-Jan-01, to lugnet.robotics)

Why not eliminate the vagueness of RCX's output circuitry altogether by running the motors from a stabilized bench supply set to 9.000 volts. That's is what I did when I characterized all my motors. I measured the rpm and wrote it on the bottom of (...) (25 years ago, 15-Jan-01, to lugnet.robotics)

I did it both ways, and got the same results(the order, not in exact speed). I think that the motors are 'tuned' in some way, because random error cannot occur 100% of the time. All motors went slower with the cable turned or the RCX on 'Reverse', (...) (25 years ago, 15-Jan-01, to lugnet.robotics)
