This project collected some dust for a while, but now with a dedicated spot on my table, I want to give it some thoughts and love, starting with some different LEDs. I've ordered diffuse orange LEDs and I will try them out on a spare board, testing if this will increase the readability. I'm close to putting an ESP8266 in there and play around with the "program over air" code or connect it via serial to my Raspberry PI. I like the thought of working on it without taking it apart to get to a serial/usb thing on there.
