lol, was coming to this thread to post about my own projector project that has sidetracked me.
The story goes....
I bought an old XVGA projector for $50 to trace images onto canvas because I have very little talent and would like to do something other than Bob Ross landscapes.
A week later I'm at the fabric store and blackout fabric is on sale for $3.50/yd. So I figure I might as well make a screen to get some more use out of this thing.
I end up with a 4ft tall 4:3 screen based on wanting to do the least amount of cutting (work).
Then I get tired of moving the projector around and worrying about something damaging it, so I buy a ceiling mount.
At this point I have around $100 in everything and something like a 80" 4:3 screen.
The DVI input on the projector won't partake in all this HDMI "handshaking" BS, so I'm forced to use either the VGA or component video input.
It works ok with an old Seagate media player, but the player only does Netflix and Youtube.
So I spend another $35 on a used HDMI to component adapter which much to my surprise works wonderfully.
The picture is better than expected for being 720 or less...whatever this thing is putting out.
So the picture looks good, but now I've got an even smaller 16:9 image on the 4:3 screen.
While watching a movie, I enlarged the image to use the full height of the screen and run over the sides.
Now I'm impressed. This feels like a theater rather than just a large tv.
I believe it would be around a 100" 16:9 screen at that point.
....so now I kind of want to build another screen......and buy a better projector.....and get some new furniture.....all because I picked up a $50 used one to trace stuff with.
