This compact and beautiful keyboard is designed to speed up your most important tasks!

It can be built using some hand-wired mechanical push switches (no PCB or diode matrix required) and controlled from a Raspberry Pi Pico RP2040 running CircuitPython.

A must-have for programmers: Ctrl, C, V, backspace, haha!

There has always been a question: where did you get such a beautiful box?

You can program and define key functions by yourself. For example, you can make game combination keys

I thought you 3D printed it yourself.

This is true for electronic engineers, circuit boards are easier.

The author is amazing, it looks very good. How did you make the shell? Is it 3D printed?

This is possible. It can be used as a key wizard.

Yes, DIY keyboard is more fun

It should be painted, otherwise it wouldn't be so smooth. Maybe the printing material is higher quality.
