(...) While in theory, this sounds very cool, in pratice, I doubt it will work quite that well. The biggest problem will be that the standard touch sensors may not be 100% on when you press it. This means the sensor itself can provide some (...) (22 years ago, 9-Sep-03, to lugnet.robotics.rcx)

(...) I don't think that would work very well, as the lights have a rather low resistance, lower than a pressed touch sensor ((URL) as a purist you can use the cybermaster sensors to multiplex three inputs ((URL) Jürgen Stuber <stuber@loria.fr> (...) (22 years ago, 9-Sep-03, to lugnet.robotics.rcx)

(...) LEGO purists use LEGO light bricks as resistors. I created potentiometer bricks, where the resistance is variable for each brick. Two stacks of 4 potentiometer bricks can be seen to the left of the RCX. In this case each stack puts the (...) (22 years ago, 9-Sep-03, to lugnet.robotics.rcx)

You can use four touch sensors per input port on the RCX. The Cybermaster touch sensors have resistors in parallel, and this is how the Cybermaster knows which implement is attached to the tracked robot. It uses its sensor input as a temperature (...)

(...) How many RCX's do you own? If it's just 1, then get RIS 2.0 and get an add'l RCX at some discount on Brickbay or something If you have tons of Technic anyway, the add'l RIS parts is pretty much irrelevant--you'd get them from the 'Hoe and (...) (22 years ago, 8-Sep-03, to lugnet.robotics)

How important is it to have more than one port with DCC capabilities. The reason I'm asking is that it "would be (...)
