In my work I recently had to perform a few ownCloud installations for customers looking for an alternative way of sharing data. So why not make a short tutorial about it? I use ServerPilot to manage some of my servers. It’s neat in that it performs the installation of all the necessary components and have…

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…

Project Goals The goals are somewhat far reaching and I’ll add links and information as we go along. Trains Rechargeable battery powered. 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!) –…
