[sdiy] Question how to improve rotary encoder feel

[Julian Schmidt]

I'm all ears if you know a part number or source for affordable endless 
pots.
All I can find are expensive industrial ones in the >10€/piece range and 
although being 360° endless rotation parts, the resistive taper spans 
only 340°
The Ion pots look more like the normal, cheap 1-2€ pots but my research 
turned nothing up, yet.
