With help from a German NG I finally got my Ubuntu to run full screen. 
Much easier on the eyes looking at a layout.

Nice job. The only thing left is to decide what to do with the circuit 
ground. Wherever safety regs permit I always run that straight to all 
the bolts. Whatever you do never leave that floating about. Same for the 
enclosure. Of course if the enlosure is plastic this doesn't matter.

After that it's, as we analog guys always say, "just software". To be 
honest I am afraid you'll have to measure more than just the kilowatts. 
  For example you probably want to know pressure curves during the time 
the well pump comes on and how hard it runs as the pressure builds.
