Hi all
short update on the status previously posted
[here].
I've just replaced the controller board on the Schreiner Schmidt KG-20 with the one Milan is making available (MFG SiMM8Rge).
I'm quite happy because his software allows to adjust the sensor resolution to match the physical range of the stick movement. I now have 4000+ increments compared to the around 400 the original setup had.
