(...) One approach is to use a linkage mechanism in which the gate is driven by a link that no matter how the motor rotates, never takes the gate below horizontal or beyond directly vertical. That of course introduces other issues, such as knowing (...) (20 years ago, 17-Dec-04, to lugnet.trains)

I have a couple of newbie questions about things like this. First, how do you protect the motor? In this particular design it looks like you could actually rotate the arm past vertical, which I guess isn't a problem until you hit the ground on the (...) (20 years ago, 17-Dec-04, to lugnet.trains)

(...) In fact for realistic operation (if you really want that!) you'd need 4 sensors, because the "exit" sensor is much closer to the crossing than the "entry" sensor in real life. But who wants realistic? This is LEGO! ROSCO (20 years ago, 16-Dec-04, to lugnet.trains)
