    Or you could go DIY and build your own projector. For less than $200 in parts (including a bulb that will last 12,000 hours and only cost me $10), I just finished building this (the wood still needs staining).



    Screen shot on a plain gray wall, about 100" diagonal. Resolution is only 800 x 480, but for a big screen on the cheap, I'm pretty happy.

    WOW! can you point me (us) in the direction of your resources for this project? also, what sort of features does the DIY projector have? can it switch between 4:3 and 16:9, do progressive scan, etc? the screen shot of it's projector looks great, i'd really be interested in doing this.

    Well, in the interests of full disclosure, you will probably have to do a LOT of reading before you can even start a build with any confidence (and hope for decent results). You will also have to luck into some serious deals on ebay to keep costs as low. $300 is probably a more realistic number for your average build. You will also need a light-controlled (more or less lightless) viewing environment. Overall brightness is the biggest drawback to DIY (though it can be alleviated to a certain extent with higher wattage bulbs).

    My PLOG (projector log) for this build can be found here.

    Take a look at the references and tutorials section at Lumenlab, and thoroughly digest both the basic .pdf guide and the more current wiki (you may need to become a member to to get access to the latter).

    As far as aspect ratios and other features, that all depends on the LCD panel you choose. The more features/higher resolution the harder it will be to find a good deal. I kept costs down by scoring a high-end portable DVD player for very cheap and harvesting the panel from that.

    Sorry about hijacking your thread Scott (and I have no doubt your CRT destroys my lowly DIY build). The enthusiasm of a newly completed project got the better of me.

    That is truly amazing . I would have never thought of building one myself . I dont even think the gurus that repair and mod the expensive ones have ever tried anything like that . It just goes to show you what a little ingenuity and a lot of hard work will do for you .
