No-lathe extruder interior
Some were a little puzzled as to how the interior of the no-lathe extruder works. As I'm putting a few together, I took a photo showing how it combines the ideas of a simple locknut thrust bearing and a chopped-up drilled nut being used as the bearing behind the filament contact point.

I've got a half-hearted attempt at an interrupt-driven speed controller firmware for a single opto endstop as a speed controller.

It works for the BitsFromBytes encoder wheel : it probably needs some tweaking for the timings for this version.
It's not currently tested properly but appears to work on my system.

I don't think you pinched the lock nut thrust bearing idea from me. I have never used or advocated one. Infact, you blogged it here in 2005, before I had heard of RepRap.

The closest thing I have used is a ball bearing between two nuts for thrust and two acting as rollers at the pressure point. hydraraptor.blogspot.com/2009/04/dinosaur

And typing fail on my front. The "More expensive ..." comment should be at the end of course.
