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.

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?
