Kerbal Controller
The article "Kerbal Controller - the Basics" https://www.instructables.com/Kerbal-Controller-the-Basics/ introduced me to a small but awesome #SimPit community on Discord.
It's also of interest for people not into #KSP as it describes the basics for DIY controllers of any kind very well.
The control panel used for demonstration has another bonus going: It's completely modular and can be 3D printed at home.
Can recommend 👍
