Welcome to the very first Tech Tuesday video. This is a new series on the oorail channel where we will be walking you through innovative model railway projects using analogue and digital electronics, including but not limited to Arduino, Raspberry Pi, Android, ARM, Linux and much more. We will be helping you modernize your model railway layout with projects as simple as lighting control, all the way up to more complex automation and signaling projects. All of the code used in Tech Tuesdays will be available for free via GitHub under various Open Source licenses.
