You would need a larger fresnel lense the size of screen to make the light ways equal when they reach your eyes. The longer the light rays are the darker they are when they reach your eyes. Once you get it build you notice that the screen is %100 viewable from a distance and at eye level, this is because the light rays coming from the projector are not the same length, thats why the center is brighter than the other areas around the screen. ![]() Once you get it just right build the rest of your frame around it. Now here is were the trail and error come in, you have to figure out how to position your mirror and projector to get a image that fits you screen and is focused. Mine is made with the Sony PSone Lcd, a 42 watt(2700 lumen) compact floruescent light bulb and the Figinon rear projection tv lense.īuild a frame for the screen just something to hold it up, my screen was made from a piece of plex-glass and a opaque show curtain. Now for the projector, first build it so that the image will show correctly on the this mean that it shows up on the wall like a regular tv. ![]() You need a large mirror if you want to keep it small and keep the image bright. After you figure out how big you want your screen find a mirror that is a couple of inches smaller than your screen or one the size of screen. To start out figure how big you want screen, 40" to 50" inches are easy to make but 60 and up are harder, unless you are going to but the projector directly behind you screen. I'm here to help anyone who is interested in building a rear projection, I have succesfully build a rear projection tv use a design I found at I don't know if there are calculation that you can use to figure out how far your projector from the I just used trail and error and it works. ![]()
