I have previously posted texts regarding my adventures in RGB-panel land, first here, and then here.
To make the office a bit extra Christmassy this year i decided that I wanted to display some scrolling text (no problem at all) with emoji (great problems). The fonts supported by drivers for these panels have letters, and just the boring ones, not even the cool Å Ä and Ö. To expect unicode support was a bit much.
After some googeling I found someone who uploaded PNG-images of thousands of emojis cleverly named after the multibyte sequence that represented the emojis. So with a bit of coding it was easy to detect the emoji in a string and replace them with the images.
To make the four individual displays sit nice I printed some brackets that used the existing m3 thread inserts on the back of the panels and added the old crusty Raspberry Pi I used for the panels from the start.
