Yes, I'm using the MPJA pwm speed controller for dimming LED's. In the
attached jpg. you can see the string of led's across the top of my panel
which are controlled by a single MPJA speed controller. I too
repositioned the potentiometer with a remote unit of higher quality. All
of my circuits were configured from the manufacturer to operate on 12v
as the MPJA pwm speed controller is designed to operate a 12v motor.
Works great with no noticeable flicker.

Thanks, guys. As often happens, I must've done something wrong. I'll

need to double check again that I got all the resistors in the right
places, and then schedule some time with the O-scope.
BTW, just for the record, I drilled a second 3/32" anti-rotation hole
for the supplied potentiometer so that I could stick it through in the
other direction. I did this AFTER checking that it was a simple,
center-tapped pot. This lets all the jelly bean parts go inside the
supplied box (drill ventilation holes) which I can then bolt up to the
backside of my panel with the control knob sticking through.
