I remember seeing that someone designed and was reselling a PCB that fit in a regular ol Casio digital case, and it did a bunch of cool stuff. I cannot find it and was hoping I could get some fellow watch nerds on the case.
Please help out if you can, and thanks in advance.
Was it this?

I think that it was, I found this too after I had typed PCB, I thought why didnt I search it and ended up finding that site. I can’t really say for sure, but it was absolutely in the ballpark.
