This is a custom built mechanical keyboard. Everything except switches and keycaps are custom built including pcb and case!
I always wanted to get a mechanical keyboard but It was to expensive to get. But, I learnt how to make simple macropad by hack club event "hackpad" and started working on this. Also, I liked the idea because everything was customizable including silkscreen on PCB and every behavior of keyboard.
You can work on the same project or benchmark this if you want to. I have all source file or link to source file of the project in this repo :)
