Now I've made a couple of new YouTube videos (one's not quite published as yet) I thought I might like one of those counters, that people have in their videos... Techmoan has one...
It would seem sensible to utilise the big filament clock display...
So there's some different code at https://github.com/andydoswell/filamentclock...
There's no change to the hardware.
If I ever get to 10,000... I'll need another digit.
