Hello guys, at some time i started to think about getting a projector but they are very expensive , and cheap ones are very bad. i am thinking now that i wont loose much by making projector myself instead of buying cheap one.

Factory sale! LED Projector DIY Lens Focal Length f=180mm DQPL F180 Projection Lens for 3 7 inches Projectors LCD-in Projector Accessories from Consumer Electronics on Aliexpress.com | Alibaba Group ? ,So my problem is i have no idea how projection lens parameters efects final image and want fresnel lens to fit the projection lense , maybe someone has any sugestions? I have space between projector and wall from 4-5 meters, is my 180 lens suitable for my setup or where is a better option?

I know it's an old post, but have you had some success with the G3 Screen, I've been thinking of doing something similar.
