Pneumatic Switches
I have tried to make motorized Lego switches for some time now, but I just can’t seem to get the to work with any reliability. Lego train switches are, in my opinion, horrible. They are extremely stiff to actually switch and gives a horrible cracking noise when you do and even then they aren’t too…

A train needs power and I don’t want to use the metal tracks even though this would be easier. The reason for this is that I don’t want to get dependent on tracks that…

Project Plan: Lego Trains
Project Goals – Control two Lego trains using an Arduino board (Success!) – Control switches using an Arduino (Nope) – Track train movement, track occupancy and switch status (Partial success) – Automatic route scheduling, track planning and train driving (Nope) – Working train signals, Swedish variant with two lights (Nope) – Working collision avoidance (Success!) –…
