Beginnings of a Computer Controlled LEGO Train Layout

Modular Train Layout
For the last few weeks I have been putting together a Modular LEGO Train Layout. Each Module is based on a 900mm X 1200 X 6mm MDF board mounted to a 70mm X 20mm Timber Frame. The Module use a series of Dowls and Holes to join the Modules together. This arrangement allow for easy storage and transportation to LEGO Shows and Displays.

Connecting an Arduino to a Raspberry PI using I2C

Raspberry Pi connected to Arduino via I2C
I’m intending to use several Arduino Boards as a cheap means of controlling a number of RFID Readers which will be used to detect the position of Locomotive Engines on my LEGO Train Layout. That said I need a way of connecting these Arduinos to the Raspberry Pi which is the Master Controller for the layout.
The easiest way of Connecting an Arduino to a Raspberry PI is using USB, however the PI’s USB ports are need for WiFi Keyboard, Mouse, etc. So in many cases USB is out, especially if you are using a Raspberry Pi Model ‘A’.

Using 16-Channel I2C, Servo Module with Raspberry Pi

Servo Board
You want to make a cool robot, maybe a hexapod walker, or in my case I want to use 9g Micro Servos to switch the points on my LEGO Train Layout I’m constructing. Or maybe you want to drive a lot of LEDs with precise PWM output. Then you realize that your Raspberry Pi only has a single PWM output on GPIO-18! What now?

Matching Ore Carrages for the LEGO 60052 Cargo Train

I have been designing some Ore Carriages for my new layout which will match LEGO’s new 60052 Cargo Train.

Creating Custom 90° LEGO Train Points for your Layout

Railway Points Modifications
This article aims to show one how too create custom 90° LEGO Train Points I made for my LEGO Railway layout. The reason for creating these custom 90° LEGO Train Points, is that the resultant 90° turn is half the width, when compared with a regular LEGO 90° Point arrangement. And hence you save on valuable Track Layout real-estate. The out of the box set-up requires 4-pieces of track instead of 3-pieces to create a 90° turn. Also by using these custom 90° LEGO Train Points, you end up with many more new layout options as a bonus.
