Hi, I'm about to start a diy projector. I don't want to waste money, that's why I'm opening this thread.
I want to use the projector for playing movies (dvd player), PC and maybe a sony playstation 3 (blue ray!! 😀 )
My room is like 4x4m long so I need to build a projector with the ability of projecting a big image at a small distance. That's why I choose a 17" widescreen LCD
Resolution 1280 x 720
Pixel Pitch 0.291mm × 0.291mm
Brightness 250 cd/㎡
Contrast Ratio 5000:1(DFC)
Viewing Angle 170/170
Response Time 8ms
Display Colors 16.2M

It's difficult to buy the fresnels here but I found two, both 17", one with 330mm focal length and another of 550mm focal length. What should I use?
Then for the triplet lens I can get of 265,327,345 and 500mm focal lenght, or variable focal length:
260-310mm
275-320mm
310-360mm
what combo should I buy??
thankssss
