For this project I ordered an e-paper / e-ink display. The goal was to have a website where I can send an image directly from my phone to the display. My dithering project came in handy (https://dev.thecell.eu/floydSteinbergDithering/) or on Github (https://github.com/TheCell/devSpace/tree/master/FloydSteinbergDithering) where I converted an image with Floyd-Steinberg-Dithering to black and white.
The project has a website where I convert the image to black and white and send it to a mysql database. On the epaper side is a raspberry pi zero polling the database for new entries. When the node server running on the raspberry finds a new image, it downloads the image and executes a python script which uploads the image to the canvas.
