[simpits-tech] Teaser pics...

[Joseph Fagner]

Let me know how the sheet thing works Gene.  I just bought a projector this
past Friday, Epson 73c LCD with 1024x768 with 1500 lumens.  Does a nice big
picture with fairly short throw but I have only tried throwing on the wall
(which surprisingly does a pretty nice job and it's not even a white wall).
I can't throw it to the rear as I don't have the space (although I made sure
the projector can do that for the future) but am looking into an affordable
screen option for now.  I am currently in a small scale police action with
SWMBO for space to put the simulator and projector.

Yes.  This is our 3rd generation effort.  The first was a proof of concept
where we hung a twin flat sheet from the cieling.  This worked out
astonishingly well.  For the second version, we built a 8' x 3' frame that
used a sheet of white .030 ABS plastic as the screen.  This didn't work
out so well.  The plastic cut roughly 75% of the light passing through it.
It was *very* hard to see if there was any light pollution at all, and it
didn't show night scenes at all - not enough light was getting through the
plastic.

This new effort uses a 9' x 8' screen frame made of 2x4 and 6 "L" brackets
per corner for strength.  The screen material is a queen sized flat sheet,
made of 230 thread per inch fabric.  I hope to be able to test this on
Saturday night.

This screen will be positioned at the end of the nose instead of right in
front of the windscreen like #2 was.  The hope is that the larger view
will provide a more realistic view.

BTW, the projectoion system consists of a second hand 800x600 LCD
projection panel sitting atop a 4000 Lumen 3M Overhead Projector.  If
you're going to do rear projection this way, 4000 Lumen is pretty much the
minimum if you want good daylight scenes.
