Alright, got all my parts in 'cept an lcd. While I'm waiting for that I'd though I'd go ahead and post my design up here.

My primary goal is to have no external moving parts. The box in box design that most people do just doesn't cut it for where I live (a college apartment). I need something much more sturdy. So.... if I cant move the projection lense, then I gotta move everything else, so here goes.

The premise of this image is the slab that the light and lcd is mounted on. I have a pair of drawer slides (the solid bearing kind, not the rickety rail ones) that this slab will be mounted on (the control panel for the lcd will be on the bottom side of the slab, not sure where i'm gonna put the ballast yet). I've rigged up a remote control motor which will be mounted to a long bolt. The bolt will go through a nut mounted on the slab, so as the motor spins the slab will slide in and out.

The big problem this introduced was the glass heat shield. since the whole thing is moving I can't really seal the whole box with one sheet a glass, so I created a smaller glass-fronted box that the bulb will sit in (vented on the back).

Only thing left that I have to consider is some kind of skirt around the front of the slide so that no light can get around the lcd.

oh ya also wanted to mention that I am prepared to handle the job of extending the cables to the input and buttons for the lcd so it will have enough slack to move.

I thought about doing that too, but then I realized how much extra work it would be. Good luck with your design!

The only problem that i see what that design is that if the lenses and lcd are gonna move...you might have a problem with cooling. The slit on the top of the box will be off if the LCD panel is moved too much in either way. Maybe somone has a idea how to get around it?

sry forgot to explain that (you didn't think i forgot something did you? ). anyway the intake will be under the slide, with a chute thing i don't really know how to explain to direct the air onto the lcd. ignore the gap i drew in the bottom of the left fresnel, as the air will be escaping above.
