If anyone is interested in a little script that grabs an image from a webcam pointed at a 7-segment LED display and returns the numbers it finds, let me know. It uses the ironically-named “Let’s Go Digital” training set for the Tesseract OCR program. It works somewhat poorly, but good enough to read my hydronic-heat boiler’s display to let me know that it didn’t fire up in the middle of the night, so that I can get up and clean the flame probe.
