> there wasn't really meant to be any practical use for this project. I immediately thought of a (sort of) practical use for the project, syncing the time on a 20th century electric master/slave clock system. If you don't know, slave clocks ran off a master pendulum clock which sent them an electric pulse once every minute to advance their hands and keep them all in perfect sync. I built a master clock replacement out of an ESP32 dev board that keeps all my slave clocks correct using NTP, but I still have to manually adjust if they get out of sync due to a power outage. If the master clock could see them and read the dials, it could sync them without any intervention. Additionally, I've got an idea for a automatic time setting system for an 18th century grandfather clock that would be a lot easier if it could visually read the hands.
