Display block number

Hi guys,
Has anyone already thought something like blockclock integrated with Umbrel ?

I’m not a developer but I think all we need is connect the Rasperry which we’re running Umbrel with some epaper display or something, I’d be very cool.

I mean insted of buying the famous “blockclock mini “ .
I found this online: https://github.com/pinheadmz/ClockBlocker
But I’m not able to make it run by myself with Umbrel

Enjoy the ride
