I made this when I was working on a poster for OpenSauce to show off one of my other projects, the Grapple Probe https://hackaday.io/project/204980-grapple-probe. I had ordered some voltage meters from Amazon, but I didn't realize they were too small, and couldn't find bigger ones in time so I made my own and I think they did the job!

It's basically an HT16K33 driven display with a KB2040 or a RP Pico attached to the back of it. Instructions, firmware, and bezel stl on the github page.
