Pi Adapter 3

train-controller

A Z scale model train controller with web interface.

You will find detailed instructions at http://www.aerodynes.org/ . This repository includes both hardware design files and the software you need to build the complete project.

The whole system is working well, and has been running for a long time on an actual layout.

Repository structure:

arduino: arduino sketches for the train controller hardware hardware: schematics, boards (Eagle) server: the node.js server that interfaces with the controller and serves the web app

Installation:

Please refer to http://www.aerodynes.org/ for detailed installation instructions. Below is a quick summary:

• Build the cape - Eagle files are included, all components are referenced in the design file, it is fairly straightforward.
• Install the arduino firmware on the cape: you can use the very good "ino" command line interface for doing so.
• Install Ubuntu Linux on your Beaglebone Black
• Install the latest nodejs distribution, and clone this repository
• Install mongodb (Ubuntu package is fine)
• Run "npm install" then "node server.js"
• ... you should be set!

Credits:

Thanks to the creators of the PID and aJson libraries (be sure to use the latest aJson library as I contributed patches to make it more robust). Thanks to Christophe Coenraets for his great tutorials which were used as a base for the server

Run as a service

Use resources/train-controller.service and copy it to /etc/systemd/system, then:

$ sudo systemctl daemon-reload
$ sudo systemctl enable train-controller
Created symlink /etc/systemd/system/multi-user.target.wants/train-controller.service → /etc/systemd/system/train-controller.service.
$ sudo service train-controller start
