Regarding the display question:
The guy you also want to communicate with is Brent Regan. He has licensed
his product to North Star and Brent claims the color LCD display is 800 nits.
I have seen it in sunlight and I believe it.
Someone is advertising a heads-up display he has designed and built on some of the used aircraft web sites. He states in the ad that he used the display panel from a current model Pontiac - apparently they offer some kind of automated display option. Anyway, I don't know how bright it is, but a display designed for automobile use is probably going to be quite rugged, and may be worth investigating for other uses. Clearly, the information needed to interface it to a home-brew system must be available.
