 "This document describes phase I of our home theatre projection system: building the prototype. In phase two, we'll be creating a permanent enclosure for the whole thing but that's for another day.
Ever since we decided that an item as mind-numbing as a television set wasn't something we actually wanted to have taking up space in our home, we've been stuck watching DVDs and the occasional CSI (via an ATI hauppauge base TV tuner card) through the computer. Hardly comfortable. So we started considering various projectors, which could provide a badass wall-sized screen without taking up so much space or costing a fortune.
There are a host of LCD projectors available, that offer a lot of features in a nice stand-alone package. You can expect to pay more than $1000 for these, which I feel is acceptable for converting your living room into a projection theater. A little research, however, uncovered a disconcerting fact: the bulb replacements are really expensive! Do a quick search, or have a look at any random replacement bulb at LCD Projector Bulbs: replacements lamps will cost anywhere between $300 and $600 (USD). Unacceptable! It is insane, and must be nerve racking, to never know when you'll next have to dish out $400 just to watch a movie.
A little more searching uncovered a number of DIY projects for those with a more hands-on bent. These are split into two main camps, the fresnel lens and the transparency projector techniques."
