PWM controlled VFD for Dewalt or Makita router speed control?

I am in the research phases of this idea and just posting this to see if anyone else has went down this road…

I think what you’re asking after is covered at: http://www.shapeoko.com/wiki/index.php/Spindle_Control#Speed_Control — there’s been a bit more discussion on this on the Shapeoko forums — let us know if there’s anything notable I missed.

Mental note: need to clean up / edit that page…
