Has anyone ever done this or know anyone who has?
I am thinking about giving it a try just for the hell of it. I really want one of these, but want to wait until I can afford a really good one, or the prices drop enough. But for the time being, I may do this for the fun of it :P

I was going to add that into this thread but it didn't seem anyone was interested. :P
I was pretty amazed at what they are doing and how the quality is, now I just gotta decide what I want and get to finding parts :)
Off to check out your other links because I stopped with lumenlabs when i was googleing.
EDIT: I had no idea that this was such a popular hobby... I had never heard of this before yesterday when i googled for projection tv :lol:
Check out the quality of this guys pictures :ohmy:
Dont all you have to have is a projector with AV inputs and a blank wall?
But they are expensive. The cheapest I have seen is $1,000.00 and the current cheapest arount here is $1,300.00.
The projectors these guys are building have better/larger pictures in general and cost anywhere from $200.00-$500.00 unless they go crazy and build monsters :lol:
And I think I was unclear on the title of the thread, these are not tv's but projectors.
I'm researching and am going to build one (unless someone is nice enough to give me a new one :P ). They seem rather easy, it is mostly the appearance of the projectors body that seems to be the tough part, so I will just need to have lower standards and focus on the picture :D
all i need is a 15" LCD now :lol:Quote:

It'd be sharp if someone made a box that hangs from the ceiling with the projector housed in it. That's alotta weight though.
My cuz has an overhead projector (I think it was about $1500) with a screen that cost $300.
He loves playin' Socom on it.
I'm going to tell him about this. He shouldn't have much problem being an architect and into computers.
Thanks for the site.
They do :)Quote:

@ Spicker
Good luck :) They are coming out with lens sets that will accomodate 17" screens as well so you would theoretically get even better resolution from the projector :01:
I am still deciding what kind to build because I cannot modify my house, but I want it to be out of the way. Thinking about a column version I saw so it sits behind the couch and projects over our head :P
OHP and LCD monitor "in the post". got some wood, an old powerpack and some fans too :01:
im just in awe of how damn good his picture looks, my DVD player doesnt even give me that good a picture. might read up on this, id enjoy playing games at that size, that makes my 23" look like a toytv
anyone else making one?
post pics of it :D
i will :shifty:
Me too :P But it'll be some time before i get one finished :(
Oh well...I'll just savor the anticipation :lol:
oh dam thats great!!! :)Quote:

BTW folks, the "Lumenlab 15" DIY Projector Guide" can be had on eMule if you don't want to pay the twenty bucks.
The guide is not what I paid the $20 for, it was the ideas and advice in the main forum. Of course i'm a bit of an idiot, so I need all the help I can get:P
i don't think there's really that much to it. just an even distribution of bright light on the LCD and a lense
Yeah but...

(not a good one but....)
before i was experimenting and managed to make an uber pin hole camera
likewise...
close off all windows in room - make small hole in one -add lense at right distance - project whats outside on your walls
i got a shoe box, stabbed a tiny hole in one end and a tore bit of card off the side. then put a cover over my head and the box, and stood on the landing (dark part of the house cos it's in the middle) and pointed it through my sisters window. i spent a few seconds fiddling with it and all i could see was a white triangle on the back of the box. i moved it and was quite startled when i got slightly blurred but still clear and recognisable picture of the garden :ohmy:
i know how they work :dry:
:P
i got a couple of guides off Emule....
lmk if u want them
nah thanks, i reckon i can work it out.
i was supposed to have the goods today but now i have to wait until friday :dry:
i wanna start making the box or something but don't know wwhat i'll have to fit into it
i was doing some research and found out that if u make a projector using OHP (over head projector) the life of the bulb is only 50-100hrs and if u make one using the guide at lumenlabs its 10 000hrs.... :lol:
the bulb for OHP=$10
bulb for lumenlab thingy=$40-50
A real easy way to make a projection TV is to go to you're local jr. college or university, wait until class gets out. When everyone has left the room, take the AV equipment. You've gotta make sure you're dressed in coveralls and if anyone walks in just say you're repairing the equipment. In college we had a savage projector and screen we took from one of the humanities buildings.
I figure for 5,000 dollars a semester I'd better at least be getting something out of the deal.

Maybe you should actualy do a little research on this one. If you did, you would know that what you just said is nonsense.
Hell, just look up the bulb info in their store and compare it to bulbs found in the OHP's and retail projectors yourself. You would then know that what was said about the lights is true.
I was just as suprised about the differences in bulbs (and their prices) myself, good thing I have read around a bit :)
It is worth the $20.00 just for the information and experience found in the forums from many people who are building or have built these things themselves imo.
The guide is just basic info, the forum is much more.
Good luck on your project :)
you've made one?
Not yet... But I do not need to make one to find out that
Is nonsense. Just need to look up the information and see specs on the bulbs etc.Quote:

I am not saying you should join their forum, but to call them a scam site because they charge you to get into the main forum is silly too.
It is a 1 time fee and the help/research is ongoing.
Great info in my opinion but to each their own :)
well i have made up my mind and i am not going to spend $ 200 on some cheap psone screen one....im going to make a nice custom built 15" LCD one....i want good results... :)
sure it'll cost about $500CDN but knowing that u built it urself....priceless
uhh guyer...ill pm u the guide which im using..
it should be free. i bet if we bitched hard enough we could get a "home-made projectors" subforum in here to paste all our discoveries and so on, we might even get more members join the forum just for it and could use other peoples free sites for extra info, we wouldn't have to pay for that.Quote:

P.S i wouldn't try with an expensive screen straight away, i hear they're fragile
Do u know any good forums?Quote:

In the free forums you get a basic idea. But I see no problem with them charging to get into the main forum. It pays the bills.
I think the average price people are paying for screens is abou $150.00 to $200.00 so you do not need to go too expensive. You can even rip out something you have laying around. I am thinking about asking my wifes boss for his old monitors.
It would be cool if enough people here were interested enough to get a sub forum. I wouldn't post their guides though, I believe they copyrighted them :lol:
