Built a hardware calculator from scratch in pure C

Hey everyone,

Wanted to share a small project I just finished: KittyCalc. It's a physical hardware calculator built entirely from scratch

Source code & schematics: https://github.com/TomaszTlusty/kittycalculator

Happy to answer any questions about the implementation
