Hey Peter, it's absolutely impossible to add anything to what's already said. You have rightfully earned the complete and total respect of the entire community here.
If not too much to ask, I would love to see some more shots of the IP if at all possible...now that all is put together! It's the 'office' that always ties a build together for me, and I know that's an area of particular pride for you as well.
Any chance of some finished 'hero' images of your magnificent gauges?
As for the rest - what can be said, but BRAVO!!!
