(...) I've drawn a circuit to control more powerful motors (sadly in Visio format at the moment, though I my convert to jpeg later to post it). Since the H-bridges have flywheel diodes across the transistors, this will short the motor when the (...) (20 years ago, 5-Aug-04, to lugnet.robotics.rcx)

(...) The amplifiers definitely won't work. I am bringing a demo 'bot to BrickFest which uses the buggy motors with an RCX. The RCX actually drives regular technic gear motors which drive a cam shaft which operates the buttons on the 9v (6 x AA) (...) (20 years ago, 5-Aug-04, to lugnet.robotics.rcx)

(...) 2.0 adds new programming features which are mostly noticeable in the graphical programming environment that LEGO supplies. If you're using a different language, though, then the differences will be handled by the compiler. NQC was updated to (...) (20 years ago, 5-Aug-04, to lugnet.robotics.rcx, FTX)

(...) 1) I'm not sure these are currently available 2) They only give you independent control of two motors per RCX output (but you can connect motors together) 3) They won't work with the 8366 motors (they were designed before those were available) (20 years ago, 5-Aug-04, to lugnet.robotics.rcx)

(...) John Barnes (HiTechnic) has available a motor amplifier which draws it's power from an external source, and can control 4 motors from 1 RCX ouptut. I haven't tried one, but you might find it helpful: (URL) (20 years ago, 5-Aug-04, to lugnet.robotics.rcx)

(...) What does this mean in electrical novice terms? What is an auto-coupler? Is it possible to modify the reciever/power unit to interface with the RCX? ie maybe add an inferred recuever to interpret commands from the rcx to power the motors (...) (20 years ago, 5-Aug-04, to lugnet.robotics.rcx)

Who said you had to actually use laser? :) Google for "electronic tape measure" to see what I'm talking about (they really use sonar, with a laser pointer to show where the device is reading from). Home Depot has one for $29. Now, the biggest (...) (20 years ago, 5-Aug-04, to lugnet.robotics.rcx)
