Building the case
Assembly of this project was really simple. Basically just making a cube with a hole on one side, and a hinged door on the other. A little glue and some screws. Slather it with some paint. Let dry (optional) and that's about it, instant bird house! Oh wait. The only tricky part about the construction of this is using a drill to make some holes in the bottom of the case for air flow and the window. Now, our overhead projector's lens assembly just so happens to be centered over the projector. We did, however, find in our hunting some that were a little off to one side or the other. So just watch for that. Now as one of the main reasons for building this case is the dampening of sound, we decided that a window needed to be installed to provide some sound leak resistance. Initially we used some plexi as that was just lying around. But after some testing we found it distorted the image more than we liked. So we chose some real glass. Cutting glass was an interesting thing to learn. If you cut your own just be real careful. Finally take some scraps and glue them to the bottom to help with airflow, and cut a small notch in the bottom of the door in the rear to allow for cable access.

Finishing out the case
So, after you have all the construction of the case done, we will be doing 2 final things to it to help address the light pollution and sound pollution, just to make sure its not an issue. And while these steps are not necessary, we do recommend that you entertain them at the very least as a option. We will be using some felt that we acquired at the local fabric store. Now I will say this on the note of the fabric store types: Not Geeks! These are the types of people that never get out and experience the world. And their idea of creative or innovative thinking is using a slightly-different-than-recommended shade of embroidery floss for their "There's No Place Like Home" wall hanging or pillow. So don't be surprised if you feel really uncomfortable in a fabric store. I sure as hell did! And people make fun of geeks dressing up like Jedi for star wars premiers and waiting in lines for days to be the first one in the door for the 12:01 AM showing.... any way, simply put, get some black felt from the ole fabric store. It comes in a small patch and large sheet verity. I recommend getting one large patch and cutting it to fit. With some adhesive spray (don't use contact cement like I did), spray the inside of the case and stick the felt to it. It's as simple as that. Noise and light issues are much lessened.
