This is so cool. Our old cable company had an analog weather channel in the 1970s. Gauges were very similar to these. I saw this in action when we went in to pay our bill. It was a wood box about waist high with a glass top. The camera would pan to each gauge for a few seconds, then move to the next one. They used audio from a pop FM station.
I’d love to build one & run an HDMI splitter to all the tv’s in my house.
