u/xKoney pointed me in the direction of Kerbal Simpit Advanced, and using u/Lets_Space controller as inspiration, thanks to both. Also This guide is helping alot.

General idea:

Using arduino as "brains".
Main focus is flight, but req keys for building spacecraft is there (only need this one keyboard + mouse in game).
Use a keyboard top + bottom frame as base for the controller.
3D print a new "plate" for the keyboard.
All switches is regular keyboard switches.
Buy components that are tested with arduino and Kerbal Simpit Advanced.
No on/off 2/3/4 way switches that can complicate things when switching between spacecrafts.

Why the Keychron Q5?

I own multible keychron keyboards, and very happy with the build quality. I also own a Q5 Pro to measure on. And I own wrist rest for the Q5
Keychron released CAD drawings of most of thier keyboards, just awesome for DIY'ers, big thanks to r/Keychron Can be fund here: Keychron Github
I found a good deal on the Q5.

Design

Control Modes: Space, Docking, EVA and Craft.
1 main rotation control joystik + 1 minor control joystik. Final functionality of each pending :)
For nav in space, i only need 4 keys: RSS on/off, Prograde, Retrograde and Maneuver.
Action groups incude lights and landing gear.
LED displays are Periapsis, Apoapsis and speed.

Next step is to play KSP

And log all keys used within ~1 hour. Should help me locate missing functionality.

Please comment if you have build a controller

I might have missed some key functionality.

Maby missing nav Target for docking?
Ideas for arrows keys?

Many challanges, but main one is space / volume of keyboard. Might be limitted to arduino nano R4 + MCP23017
