Live E-Paper Transit Departure Board

I wanted a way to check my local bus/train schedule on my way out the door without having to pull out my phone, so I put together this live departure board. It uses an e-paper display, so it blends nicely into a room without glowing at you all day.

The best part of this build is the controls. I didn't want a bunch of buttons cluttering up the front panel, so the rotary encoder is actually hidden inside the little trash bin on the right. You just spin and press the bin itself to interact with the display.

Hardware Requirements:

• Waveshare 2.9" E-Paper Display(look at the pictures to get the correct variant)
• KY-040 rotary encoder
• any microcontroller with Wifi and enough pins for the display and encoder
• 8 M3x8 screws

A Note on Firmware: Right now, this is strictly a hardware/case release. Because public transit APIs vary wildly from city to city, creating a "one-size-fits-all" code solution is pretty much impossible.

I plan to upload some sample firmware in the future to give everyone a baseline to work from. Until then, you will need to write your own code or adapt an existing project to pull the JSON/API data from your local transit authority and push it to the screen.
