Intense project! I used to work as an electrical engineer adding computerized control systems to manufacturing machines in old factories. Some of the machines and process lines were in paper mills from the 1930's. So, before we came in, it would take the human operators a few days to manually adjust all of the controls to make one type or paper instead of another type. We added in all types of temperature, proximity, speed and position sensors, and they could hit a few buttons on a computer and change over in minutes. I did a lot of soldering and trouble shooting back then, so this brought back some fond memories.
