Your thoughts on electronics and electromotor drive, please…

I was searching on the net for speed controls, and found this site.


I’m not a electronic guy, but it doesn’t seem too hard to build one and give it a try on the existing extruder.
I like the idea of using a washer motor, because they are widely spread all over the world, and easy to get…

Any Idea’s?
All feedback welcome. And I can use some help sourcing the components in Netherlands or Europe.
