Well i'm fairly new to projectors but this is what i would like to make
[IMGDEAD]http://img291.echo.cx/img291/6049/projector4wm.jpg[/IMGDEAD]
I plan on gutting my OHP and LCD screen and putting it into a custom box. alot of the plans i see end up makeing a really long projectors.
I'd rather it be tall then it can just stand at the back of the room on it's own and be on axis to the screen.
doing all the cutting and electronics i'm fine with i'm just wondering what distances things should be set apart
how far should the light be from the fresnel, then the lcd a few MM above that, Then i'll measure on the OHP the distance from the fresnel to the lens and rig up some kind of way to focuse it
The OHP i have has the light mounted on the side then hitting a mirror and going up to the fresnell.
If i measure the distance from light to mirror to fresnell add them up and thats the vertical distance i need?
The light is 400w
Its set up kinda like this

whats the deal with the bit infont of the light
Thanks for any help you can give
