I made this as a gift for my fiancée. It uses a Particle Photon and an RGB LED strip.
I was inspired by the maps from this book and the map in the Main St. Station. I adapted my own version using Photoshop to incorporate some of the newer rides she considers her favorite. Then I sent the file to my brother who has access to a laser cutter. I cut out the track by hand then made an inside track to attach the LED strip.
I utilized the neopixel library to display the trains going around the park at Disneyland. I later came up with the idea to change the colors for each month.
I put the source code up on my GitHub if you’re interested in making your own.
