I’ve been wanting to get a YouTube subscriber counter clock style device for a while now after I saw a few different YouTubers with them in the background of their videos.
I saw that there was a ready made one available on Amazon from a company called LaMetric – but it was close to $200!
So instead I decided to build one myself using various information I found online.
It cost me less than $20 to build this between the NodeMCU microcontroller, LED Matrix Array, and using my existing 3D printer to make the enclosure.
Parts Used & Documentation
LED Matrix Array
Thingiverse Model for Box
Or if you want something like this and don’t want to deal with building your own, check out the LaMetric one that I mentioned on Amazon!
