- tito13kfm, on 10/12/2007, -1/+9I purchased the access to the site off of ebay a number of years ago. (It used to be $19.99 to access the forums, but was WELL worth it). I used some fresnel lenses I salvaged after getting the specs needed. I used a 7" LCD from a broken portable DVD player I got for $2 from a garage sale.
I can say that it was a bit harder then the ads had made it seem. Actually, alot harder. You better know a bit about wiring and ventillation before you start. It doesn't help to just have 1 switch that turns off the bulb and fan all in one shot as you run a huge risk of overheating and actually melting the wiring or lighting the box on fire (yes, the bulb gets that hot).
They include a list of LCD's which are easy to hack apart as some of them have extremely short cables and are unsuitable for the project. As well as recommendations on bulbs, enclosures and everything else you could want.
The quality on the 7" wasn't too bad. I could project it up to around 34" before it started to become noticably pixelated. With a 14 or 15" LCD running a higher res you could easily go 90" or larger.
Couple of tips... Don't touch the bulb without cotton gloves on... The oil from your fingers will boil on it and cause it to explode (I shoulda heeded the warning instead of saying "***** it"). And make adjustment knobs for everything, cause it takes ALOT of tinkering to get the picture in focus.. once it's done though you can just fine tune after moving it. - fanboydcs, on 10/12/2007, -1/+8Well I would never spend $1600+ on a projector that is only made for hdtv. This type of projector is made from a computer LCD and can display alot more than HDTV. I think this project is very cool, and would only cost $300 dollars or so to build. Plus it fine tunes our skills as geeks.

- Muyoso, on 10/12/2007, -1/+5UH, because if you spend any time at all building one, it will look better than an svga projector, cost a lot less than even a used one, and use bulbs that are 1/20 of the cost and last 20 times as long. Need any other reasons?
- jollyroger814, on 10/12/2007, -0/+3This is like the 3rd projecter that links to lumenlab in the past couple of weeks.
- marix, on 10/12/2007, -2/+4Neat project but quality is somewhat lacking and difficulty is quite high.
- Rangoth, on 10/12/2007, -1/+3That would be super cool but it violates my main principle of being damn lazy....
- TheG2, on 10/12/2007, -2/+4I'm looking for a projector but I feel that this is one of those things better off buying then making yourself. Any true media person would cry at the quality and I agree, the difficulty of making this is quite high.
- Ramble, on 10/12/2007, -1/+3Been done for ages.
I remember reading an article on it at Toms I think. - agilos, on 10/12/2007, -0/+2Those are some great tips tito.
- silverdragon347, on 10/12/2007, -0/+1I looked into this after Robert mentioned it on DL.TV this week, and I've been thinking of a cool case to build it into...

- Phew, on 10/12/2007, -0/+1This build-your-own-beamer project indeed exists for some time now. You can really get amazing results with this. Only problem is, besides the difficulty, the size of the beamer. The beamers really get large in size. And if you live in a small student room (like me) then the size is important :)
However, this is a nice summer project. I am maybe going to build one my own with the help of a friend of mine. I don't have enought knowledge to build this all.
The main advantage of this project are indeed the lightbulbs. A lightbulb costs around $30 dollar to replace it. The life of a lamp is 6000 hours. A normal beamer lightbulb only has a life span of 2000 hours.
If you want to see some results of people who already build a beamer, look here: http://www.lumenlab.com/forums/index.php?showforum=3 - camtech, on 10/12/2007, -0/+1Just happens that Popular Science Magazine did this:

- helix400, on 10/12/2007, -0/+1Heh, now there are three of you. It's true, you guys really do have no lives.
I personally find this really amusing. I hope you don't mind, but I'll be toying with you more down the road. - kalisphoenix, on 10/12/2007, -0/+1*takes his 15" LCD off eBay*
I tried to do this a long time ago, but didn't have any money or an LCD. Money got even tighter, so I quit. Well, let's just see about this.... - taranfx, on 10/03/2009, -0/+1Tha's pretty comprehensive guide.

I made one under $800. - donnikhan, on 10/12/2007, -4/+5how many times am i going to read this article. old not dugg
- bonked, on 10/12/2007, -0/+1Actually most people say that the quality is better than most commercial projectors and the advantage is the bulbs cost only about $20.00 US. I'm constantly worried that my Dell 2300MP is getting too much use because it's going to cost roughly $350.00 US to replace the bulb when the time comes.
- mianos, on 10/12/2007, -3/+2I'm going to mod as lame every article that's a a blog to a blog from now on. I suggest others do the same until there is some way to 'refactor' the links.
- mikeyaj86, on 10/12/2007, -4/+2not so sure about this. it's cool ... but i just don't know.
- dialdn, on 10/12/2007, -3/+1Old digg
- helix400, on 10/12/2007, -4/+1Cool stuff
- redcary, on 10/12/2007, -4/+0LAME! Why would you spend the time money and effort if you could just go buy a used SVGA projector for the same money, that will look better.
