Morning Gents,
For the past few months I have been playing with several visual solutions that have each posed their own challenges. Although this solution is not to the calibre of Jon Boe's triple projector set-up, it works great for those (like me) that are penny pinchers. Wink

Using a 1024x768 projector (2000 lumens / 2500:1 contrast ratio), Home Depot mirror, and rear projection fabric from Drazian (eBay), I was able to get the look I was after for about $1800 (CAD). Although slightly more that Tim's curved mirror and Sintra design (which I tried, didn't get the look I was after), I have got terrific clarity and brightness.

The idea actually came from another B737NG builder friend of mine (thanks Bruce), who has used a similar set-up successfully. Essentially, using PVC piping and small bungee cords, I was VERY easily able to stretch the fabric to the necessary tension, and hang it from my basement ceiling. The projector is mounted overhead of the cockpit, bounces off a mirror located on the opposite wall, and projects from behind onto the screen. I get very little crabbing effect, and once I finalize my tweaking, I intent to use black fabric to limit your view to just the FS visuals. Therefore, I will only get an 'outside' reference. Here are some pics...BTW, my sim MIP is fully integrated (every switch and LED) with the FDS SYS-3 board.

Evening John,
The company name is Dazian Fabrics. Attached below is the link to their eBay posting. You can request absolutely any size you want by emailing them. I custom ordered 4ft by 6ft, and it works like a charm for me. Definitely recommend them, and you can't beat the price. Cheers, Steve

Hi Steve,

congratulations! That view looks very realistic!
Can you make a small easy drawing about your setup?

As I understand right, you positioned you Beamer above your FD and then you bring the picture via a mirror on the backside of the Rear Cinema Projection Screen Material.
- How did you mount the material on your window`s area?
- Can you give us some details about the sizing and Distances?

Many Thanks in advance
regards
Martin

Home Depot is a chain of home building supply stores in the US (and Canada too?). These are huge stores that market to everyone from do it yourself home owners to professional home builders. The stores have a very wide selection of products, including mirrors of different sizes and shapes, for reasonable prices.

A "Home Depot mirror" is simply a mirror bought at Home Depot.

Sorry Gents for the slow reply. Here are some more pictures that should help illustrate my set-up. Let me know if you have any questions. Thanks!

Projector = Optima DX605

The projector is hung with an old camera tripod. Therefore I'm able to get terrific movement for lining the image up correctly


The mirror is angled slightly to bounce the image downward to the rear projection fabric


Using PVC piping and bungee cords, I was able to stretch the fabric to the perfect tension. Low tech solution that works awesome!


Doesn't look too pretty from the outside, but I've just bought a full 737-200 interior that will be arriving in a month! Should give it alot more character. This however, should give a complete overview.

Steve,

It's looking very good. Could you give some measurements (mirror & screen) and distances (from projector to mirror, mirror to screen, screen to pilot), please?

Regards,

Legal

-Mirror is 36" x 42"
-Screen is 48" x 72" (could get by with 36" x 72")

Projector to Mirror = 7 feet
Mirror to Screen = 3 feet

Hope that helps! Remember, each projector will vary in distance required for throw. Cheers, Steve
