I have not forgot about you! I just dont have my PJ yet (JVC RS45 will be my first PJ)!
I am currently finishing up the design of the frame. Probably going to go something like a 130" diagonal 16x9 screen at the maximum, though I plan to use 4 way masking (manual) to use something smaller for most viewing with the 130" being reserved for movies that have imax cuts/AR changes. Right now I envision doing a CIH setup (again with the help of 4 way masking) at 3.85 foot height (ie ~95" diagonal 16x9 and ~120" diagonal 2.37). Will be using either Bosch or 80/20 for the aluminum frame and will be doing something like a flip-up fixed frame attached to the ceiling on door hinges and a pulley system to raise/lower the screen.
After that is done this week I will be spending the next week or two picking out spandex materials to try (will likely order some whites, grays/silvers, and black, maybe with different glossiness, in order to test various combinations, may even through in some of the dazian materials). Will likely need to try and find some combo that gives me >1 gain (due to screen size and who knows final RS45 calibrated lumens and bulb performance) while still working with ambient light/light colored walls until i can cover those up.
I'll then build it all towards the end of November.
Then when the RS45 finally comes in (mid december maybe/hopefully), I can get to the real testing.
Am not sure at the moment if I will be attempting to spray any paint on to the spandex, perhaps when I finish the "dry" combination tests. I'd like to but dont have the spray gun and am being realistic that after the other testing, I'll just want to relax and watch some movies dang it
. But perhaps I can be convinced.
So... long story short... I have not forgot about you or others looking into the material
