Nice! Thanks for checking back in. I've admired the setup you were developing for a while. It's the kind of thing I'd love to build given the time/money. Didn't you get involved with NThusim?
Yep, I mostly just volunteer forum staff for them. They subcontracted me out for a bunch of conventions in the last year. CES was a mind blowing week to experience (especially when I didn't have to pay for it). Working AMD events promoting Eyefinity are major fun both during the events and behind the scenes in setup and tare down. I had to totally rethink my screen design a dozen times over refining it to deal with the portability aspect of doing them. When I first got into this stuff I never thought about making the screens quick and simple to put up and take down. That took a bunch of design changes and refinement to deal with. I'm still refining my current screen design even more lately. Two prototype screens are being installed in a shopping mall based simulation center in Denver in January. In order to get it to the quality level required for a consumer product, I've done a significant amount of changes lately. I have the design pretty much figured out. I just need to refine a few small details. The Denver screens are still prototypes, but a heck of a lot more functional than my last 5 designs. I especially like that Eyefinity 2x1L with just two projectors can do the FOV. It's the most cost effective way to address the issue. NVIDIA requires dual video card to do Surround and also three displays. That gets crazy expensive with proejctors. AMD 2x1L setup with just a single video card is so much more cost effective.
The difference in screen design between the two posts above is about a dozen total ground-up redesigns on the screen. Looking at the old pics, they didn't even have edge blending in those old setups. Actually, looking closely at the latest picture, that isn't even the current screen. That was the last time I used the screen I built for CES 2011.
My plan is to come up with a how-to using regular Home Depot type materials to make a cost effective reproduction of the a screen with the same dimensions as my portable one. It'll be much more cost effective that way. The downside is it'll be a fixed screen not portable. Making the screen portable makes it cost about 10x more unfortunately. As making this stuff cost effective is my goal, I think it's a compromise that is worth having a fixed screen though. At issue is having room for it. I've always lucked out with having an unfinished basement.
I feel kind of silly it's taken me this long to show back up here. Looking at my last post time stamps I simply didn't realize it had been that long.
