"PistonBroke" a Computer Controlled Layout

[OBJack]

jack when I went to tech school, they were still teaching tubes I did get a rudimentary understanding of transistor's when I did a joy class about remote control then the mine closed so I never got to apply it, so the old rusty noggin lost it.

  You are still way ahead of me Jim .... although I do have a Rusty Noggin .... I just rely on the software to do everything for me, no electronic knowledge at all, I search Google, follow Youtube "experts" or, as a last resort, read the instructions on installation.
