Lego Train Switch Servo Mount

thingiverse

I'm working on a more advanced Servo Mount for Lego Train Switch that meets my exacting standards. The existing options just didn't cut it, so I decided to create something better. Every part of this design is printable, all you'll need is an SG90 9g micro servo and a small screw (which usually comes with the servo) along with the original Lego switch track piece. I control this setup using Arduino, allowing me to experiment with it in various ways. To take things to the next level, I've figured out how to control four switches at once using an infrared receiver that interfaces with the original Lego remote control or through a custom Android application via Bluetooth 4.0 (BLE). If anyone wants to give it a try, I'd be happy to share my Arduino and Android app source codes.
