It was a single PSU, but not the same Ground wire. I was using a 4 Wire. Two grounds and a 12V and a 5V. I hooked one up Ground-5V and the other Ground-12 V. When you look at this set up on the Oscilloscope, there is too much noise. So maybe that was the problem.
Here is the video of my circuit on the oscilloscope.

I hope it looks right, and that you have enjoyed my thread. I have pulled out a few hairs doing this, and this would have been a lot cheaper if someone had just sold me one.
If this is right, I am going to box it up, mount the Potentiometer ( actually I am gonna see if the potentiometer in my sunbeam is 3 legged and 100KOhms, if so I am going to hook it up there on one of those channels.) and then I should be set.
