Dan -
Cool. So the polarity switches are motorized 5120s controlled by an RCX's
light sensor inputs? Are there two inputs and two outputs used on the RCX?
How do you limit the length of time the 5120s receive power from the motors?
Is that a fixed length, or do you get fancy and use touch sensors? Looks
like you run the motors on the 5120s for less than a second.
Thanks for sharing - I gotta try that!

| (...) the 3 polarity switches are run by the 3 outputs of the RCX, with 2 inputs used for light sensors. The construction of the polarity switches is so that the timeing on the motors isn't important - the only reason they're timed is to reduce wear (...) (23 years ago, 11-Apr-01, to lugnet.trains)
