Hey, feel free to visit my thread here. I’m not an expert at this but I will happily help you :).
SatNOGS Rotator v3.1 Build Project - Gallery - Libre Space Community
I’m using Arduino with CNC V3 shield for the controller instead of SatNOGS controller as it is readily available and cheaper.
For now I’m using my SatNOGS station and rotator separately, but I wish to integrate both, we might learn together how to do it hopefully!
And for antenna I’m using homebrew VHF QFH (recommended!) with repurposed old Raspberry Pi 3B+ that I owned from college days lol. The SatNOGS rotator wiki is a great way to start. Feel free to discuss 
btw I laughed a lot by your Inosuke profile picture
