94" of viewing pleasure. I would like to say that it looks a lot nicer in real life. I did this in about 45 minutes with an overhead projector I was given and a broken LCD I had lying around.

Comments welcome.

That is pretty neat. I am bit confused about how the setup works. Maybe a diagram. Good work.

You take one of these, you strap an lcd to it that's the right size, you aim it at a wall that doesn't have anything on it and the image becomes projected through the glass at the top.

That's basically it, but maybe you can convince stilgar to make a video explaining and showing his design?

I have been following the DIY projector scene for a few years now. There is a ton of information on http:\\www.lumenlab.com . They have a pretty good project logs forum here. There are a few pros and cons to building your own projector. When I first started looking into this projectors cost 1500 bucks and up. Doing this you could save some serious money doing it yourself. Now there are several projectors you can buy for 500 bucks or less depending on its specs. The beauty of the diy projector is the bulb. Projector bulbs are rated for a few thousand hours of operation and the average cost of each bulb is 300 bucks. In the diy projectors they are using bulbs that cost $30 and they are rated at 6000 hours plus. The sacrifice for doing this is mainly size and convienence. DIY projectors using lcds are fairly large compared to their comerical counterparts. Lumenlabs has just released a comercial version of their diy specs for $500, but I dont think the specs match what you can build yourself for that price.
Anyway great job d_stilgar looks like alot of fun!

Great job! Is it bright enough for viewing in a lighted room?
