That set up in the video is pretty much the same as the one somebody posted here a few months ago. I can't remember the guys name but he had the auto-dispenser with video cam & computer screen (I believe it was a computer screen) and he was telling me & someone else about the set up.
They lost me when they started getting into the computer / video specs & such.

As a matter of fact......

I just looked at the link again & scrolled down a wee bit. That was the video I was talking about.
Y'all should know better than to make me try to remember something from that long ago. Now I gotta take a few million aspirins & lay down.
