Building Your Own TV / Movie Projector ( Very Cheap )

I thought this would be the best place to post this link that was sent to me

http://www.lumenlab.com//?gtnjs=1

I read through some of the forum posts on their site and was really impressed by the quality of some of the images they were producing on their own homemade projectors. For a fraction of what an actual commercial projector costs (upwards of 5000 $ I hear) one can produce their own quality one. I might think of buying the guide from the website. It says on their website that building a descent one costs 400$ with new components and all.

Hi golgothurteen,

 

they mention: "The Lumenlab DIY 15" Projector is a REAL projector with a high quality XGA LCD panel, a powerful Metal Halide lamp and REAL projection optics. The so-called projection TV kits are simply a cheap fresnel lens that you put in front of your television; an image is projected, but not a watchable one".

 

It's definitely not worth paying for "their" info ... I've seen drawings/schematics for these types on some forums a few years ago.

 

I've seen the Fresnel+TV kits on an online TV tech show, and the "quality" was worthless. These guys say they use proper optics etc. What they are doing is basically projecting a bright lamp through a normal LCD (rather than one on a chip) and then using the lens to focus the image crisply on a wall/sheet.

 

I remember the forum thread I read mentioning problems of heat being the main issue .. and one guy built a bunch of fans in his.

 

All of these sites sell "howto's" that should really be free .. and they are just there to then sell their own wares!

 

Other options I read about include the use of a cheap OHP with an LCD display, and both transmissive & reflective LCDs ...

 

Kam.

Thanks for the info kam. I actually just googled the pdf guide last night and got it for free. You might be right about the heating arrangement. It just shows that you have to install a mini fan on the bulb. Might damage the other components. Hopefully others will put inut on this if they have any experiences, etc.

golgothurteen, the screenshots you have found show that the particular projectors made work well. However, how long did it take them to perfect it to such a high quality?PS: Your signature would kill a sufferer of epilepsy. Can you tone it down a little?

Hey, that's pretty cool...I'd definately do something like that to same some dough.

Well here in pretty old England, projectors can be as cheap as £140. At my school, we recently became a Maths and Computing College (status), Leading Edge Mentor and several other things. They brought in over a quarter of a million british sterling in funding. So, now every classroom has an interactive whiteboard and projector. The projectors only cost £140 each. And before anybody says that it was only that price because it was due to bulk buy, such specialised items can not be bulk baught, nor do schools get discounts on them.

For just $19.99, a Lumenlab Premium Membership will show you how! As a matter of fact you can build a high quality XGA projector for the cost of a lightbulb for a commercial projector!
A lightbulb for a commercial projector costs between $250-$600!

So it could cost you something from $250-600 ??? Still expensive, you can do that for $5 (saw it on Brainiac, but quality sucked big time )

This free guide shows you how to make one from an old overheadprojector. Ok, it's bulky, but it works too (and if you're lucky you could make it for less than $100 )

I have a question, I'd like to have a projector for my computer, but I'm concerned about both picture quality & refresh rate. I've seen some projectors that work *great* for movies, and other tv-type video, but when used for normal computer use, they perform extremely poorly. I would like to display on an entire wall, and use it for my computer, so I would need the resolution high, so that it doesn't look pixallated. Any ideas how I can do this without buying an expensive projector, or splitting the display? I know that you can use 4 (or more) low-res projectors carefully aligned to simulate one high res projector, but that would get expensive to drive that many projectors. Getting more than one vid card that could handle at least 2 outputs a piece.Also, I would like a refresh rate that is good enough that it would be possible to play a video game on it. Yes, I know that this would be a tall order, but I know it's got to be possible.-YB

why the fresnel lens and bulbs for Diy pjs.difficult to get in Nigeria? Building Your Own TV / Movie Projector ( Very Cheap )

I am a Nigerian. I believe, having the right parts for Diy projector one could have the very nice image. It’s good to build something with your hands and be happy to see it work. The idea of”do it yourself" is even good for people like us. We may keep cash to buy the commercial projector, but we can't enjoy it like our small TV we often watch programs at home. I understand that, watching commercial projector everyday will not last. Recently, I build (Pj) one for myself and I see that it can last even watching programs with it everyday. The best of it is the parts. I am lack of Fresnel lens, good reflector and bulb. They are not common in Nigeria and to import, is not simple like any countries where trust is upon everyone. I suggest those who are advertising Diy Pj parts on the websites should have branches, even in my country. 

I will like to hear from anyone that is concerned. 

Thanks.
