Artwork

I made a beach scene by taking a photo and running it through Adobe Illustrators Image Trace filter, and I'm sure you can make something creative. Try out Inkscape if you want a free image editor.

Assembly

See ASSEMBLY.md

Code

  • Fetches surf data from surfline.com
  • Converts that data into signals to adjust the angle on servo controllers
  • Runs on a raspberry pi (zero w)

Getting setup

  • Get your pi
  • Clone this repo into /home/pi/code/living-poster
  • Install these dependencies:
    • python-requests
    • python-RPI.GPIO
  • Copy poster/config.example.json into poster.config.json with the actual pin values you want
  • Hook up your servo wires according to the pin numbers in actuate.py
  • Run the script with python main.py to get live data OR python manual.py <surf_height> <water_temp> <wind_speed> to put in your own data
