Hi,
You could always just purchase one of these. :)

It does exactly what you are after.
Cheers,
Peter.

Which is something I have meant to try for a while.
I have a feeling I have drawn it before, and that time I was more
confident in it, I think I have left out

No, but I am pretty sure I know how, with push-pull optos.

are not isolated from the line voltage. So expect to have to isolate

It is a speed controller to control router speeds that is new on the

or electronically controlled. They seem to support MACH3, but not

Whoopee!
I found the info on the EMC2 site. Yes, it should be pretty easily
controllable. I downloaded the manual
for version 2 of the SuperPID that tells how to do it with Mach3. The
doc's at EMC2 are:
