This project was inspired from my Digital Resort Sign. For this project, I printed a regular trail map and added LEDs behind each lift and trail marked on the map.
Backend: Node.js/Python
This project uses the same open source project as before, Liftie. I also use this in combination with a Python script that collects the data and formats it accordingly for the LEDs. The script pushes a list of data containing a color for each LED.
Construction
The poster is glued to a single panel cut to size. Each LED had its own hole drilled for them to shine through. I decided to use projection mapping to figure out where the holes needed to go. This would help reduce damaging the poster and give me more precision. The frame was then screwed in from the back to hide the edges of the poster.
The LEDs are controlled by WLED. It has an extensive local API that allows me great control of the LEDs. It runs on an ESP32 mounted on the back of the panel.
