Searching for a Cheap Overhead Projector? 26
stinkjones asks: "I recently found a project on
Hackaday, which I found very interesting. It was linked to
Tom's Hardware, and involved a massive, and cheap, projector. I have an LCD projector, but this seems like a great project with a pretty cool result. I already have an LCD that's perfect for the job but overhead projectors are hard to find. Retail they are around $500 new or a lot more, and if you can find them used they have a huge range of prices. Does anyone know where to find a cheap one?"

If you instead build your own enclosure, you can do some neat stuff. First, you can show the full 1024x768. Also, you can use a metal halide bulb, which typically have a clean white color and put out less heat for the amount of light produced. And metal halide bulbs last anywhere from 8000 to 20,000 hours. You will also be able to get a high-quality lens for good focus across the whole display, something a cheap overhead might not be able to do.
Go to http://www.diyaudio.com/ [diyaudio.com] and visit the Moving Image forum. There are thousands of posts containing ideas, plans, calculations, optics sources, and photos. I'm in the process of building my own projector with a 400W 6500K metal halide bulb, here's a photo of the image projected by a test mockup: http://lserve.homelinux.net:7780/diyaudio/lightso

No, that's not a typo. That's really the website. We have tons of stuff (50k square foot facility) that just goes to the scrap heap. Some things are sold pennies on the dollar, because there cheaper to ship then they are to scrap.
We have, at this point in time, about 5 projectors in stock. And I bet even one of them works.

The money is used by the fellow who runs the board. He builds projectors, trys different pieces and part out, and most immportantly, gets custom lenses made for their community.
Hope this helps,

We've got a whole storage room full of the things at work. One gets trotted out for some antediluvian professor who still uses transparencies every once in a while, but most of the time they're just gathering dust. I doubt we're unique.

What I don't understand is why you have to Ask Slashdot this? The plans I saw had all these suggestions already mentioned. Check local and state surplus sales and auctions, checkout ebay, there are many places. A couple minutes of research would've pointed you in the right direction.
If you need this kind of hand holding perhaps you should start with a more simple mod, like changing a tire, or setting the time and date on your VCR.
