[simpits-tech] Display Problem

[Steve Wilson]

In my basic concept, yet to be tested by yours truly, the projector goes as
high as you can get it over the front of the cockpit, facing a point above
the back of the seat.  That point is in the center of the image that would
be projected on the "back" wall.  The mirror has to be the size of that
image.  That would make the point about 1 1/2 feet down from the ceiling or
so as a guesstimate, and the mirror size something like 2 x 3, maybe a tad
larger.  Test with a cheap bathroom mirror, and upgrade to plate glass for
optical improvement if it works.  This mirror is angled down until it
reflects the image where you want it, right in front of the 'pit.  There
will be some degree of keystoning, but you should be able to remove most, if
not all of it, by adjusting the monitor.

It *will* look like odd.  But my intuition says it should do the trick.  You
really have to get that projector high though, so that the projector lens is
as far away from the centerline of your field of view as possible.  Anyone
else think this will work?
