Well I have been sittin on my lilliput 7'' for quite some time now. Finally got all my parts and I am ready to start building.
First off like I said I am using the lilliput 7" screen, 250w mh bulb, and the 240mm copy lens from surplus shed.
I am using 1/2" mdf for the bottom of my project. here is what the laypout looks like....
I am building an htpc (mini itx) computer above the actualy projector parts. This is where the ballast, dvdrom, 40gig harddrive, and a epiavia 1 gb mini itx mother board will be.
Also in the picture the mirror is not centered. The final project will be fixed of this.

Now I was trying to think what I could frame the fresnells and lcd with. I made small frames out of Corian. It is the stuff they make countertops out of. I went to a store and asked nicly for some scraps. They gladly handed it over. Here are some pics of my frams. The ace of spades is just for size purposes.
The taller frame is mounted on angle brackets, and the front ones are screwed in through the bottom.

yeah deff...miter saw makes things much, much easier....if you plan on using corian...you can do anything but screw into it. and if you drill it...do it slowly. Corian is weird stuff, but works great. I attached the two smaller frame pieces by drilling a hole in the bottom wider then the screw and filled the hole with hot glue....then drove the screw up through the bottom of the base and into the glue filled hole. If you try screwing stright into the corian it will split....
OMG!!!
don't let the small controller board hang around like that!!! Your LCD will die in a hurry; fix it somehow or this ffc will break...

Corian
Corian is artificial stone used to make moderately expensive kitchen counter tops. (Much cheaper than real stone.) It is pretty stable in terms of physical dimensions, but you can burn it since it has some organic components.
One suggestion: Your image will be clearer if you can control the reflection of light off various surfaces. So you could paint the corian with flat black paint. Even better: Glue black felt onto it.
