I made a low res projector last year, which was a lot of fun researching and building, but when it was done I didn't end up using it much as it weighed way too much it was too bulky and ran REALLY hot.
For my second attempt I had some ideas. This one is going to be a 15” XGA with as high of contrast ratio as I can get. You really notice a low contrast ratio. I am putting this projector in my room about 8’ away from where I want to project and am hoping for a 40”X40” screen as that’s all I have room for. I am going to hook this up to my computer and use the computer as a HTPC.
I was thinking of gutting an OHP and putting a 400w HQI MH and a triplet in it. My question is the OHP Fresnels of high enough quality not to notice any drop in quality? I would build a painted black pyramid from the fresnel to the triplet to trap out stray light.
