Well since you DLPers have called it quits but are sticking around anyway, why don't you give us newbies a few insights into your past attempts... unless you want me to go back and read all your previous posts.
By the way i plan on building the first good quality sub $100 projector.

Wow it's true those DLPs give nice picture...But that photo-camera seems real good too...Can someone who has had real good experience with DIY projectors tell me if the DIY projectors look as good as that dlp picture (not the actual real DLP projection where the picture came from, but the posted pic of the DLP) in real life?
And do those dlps burnout out real fast? I mean do the little mirror chips lose a pixel or two mechanically often? Cuz it sure doesn't seem like it.

It also have the nice picture as you can see as a matter of fact it has better resolution. Those pictures will look alot better with no light and pixars monsters inc. help too. You can see the sheen on the characters almost 3d like. I will try to post starwars or some real dvd when I get new batteries for my camera. The mp8750 is just heavier and louder than the mitsu.

Diy can look as good as DLP. But the key here is CAN and that is compared to low end DLP. Right now the infocus X1 projector is 800x600 3000 hour lamp for $1200. that is compared to say $500-600 for a DIY projector with 1024x768. That might seem like a win for DIY, but a few things to remember.
First contrast ratio--The X1 in this example has a 2000:1 contrast radio while most LCD monitors used for DIY are in the 300:1 range--blacks and shadow detail suffer under DIY.
Second, the X1 has built in video scaling and HDTV. For DIY you will need either an HTPC or an external scaler (serveral hundret for HDTV support).
Third the X1 is rated at about 1100 lumens, whereas most DIY is in the 400-500 range.
And finally, it comes down to risk. DIY lcd involves buying a lcd flat panel monitor and taking it apart. The risks for breaking the panel or ribbon in this process are real and quite common---one mistake and you can be out $250. And all cost benefits go poof!

hey mike and if u drop yours? what then?lol what about the cost of your bulb? woulnd u rather pay $50 for a bulb than say $400? i know i would but yeah yeah i know it some of these bought projectors are awsome no matter the price u pay in the end, just like that sports car u can go and buy, but can u aford to run it?

My bulb is rated at 6000 hours. That works out to about 20 hours a week for 5 years. I think that went the bulb does go I will just upgrade my projector to a newer one.
mike
yeah thats right not bad, but some of these only last 2000h and if u dont replace the bulb, then u upgrade and loose money on the one that needs a new bulb, i guess these days it doesnt matter what u buy but there is always a cost, i would like to buy one for sure but money is a prob at the moment and realy i dont want to spend $400 for a bulb when it goes or a new projector, that being said it doesnt mean i wouldnt buy one, i guess its abit like computers, u always need to upgrade to keep up with the media out there or for the things that u do, i build my own comps so its cheap for me and more versitile but alittle diff from diy projectors. Anyway im having fun building my own and im learning stuff that i should have listened to at school lol but its all good either way, just upto the persons expectations and what they can aford i guess.
cheers Trev

ERRR or you can do like i am and try to retro fit it with a cheap bulb... some guy already did it and i have the link some place but im lazy, ... damnit lemme look. http://www.tweaknmod-av.tk/ i think thats it. But i plan on using a 250w or 150w hqi.
poobear
yeah thats somthing i was going to metion, this guy in that site is abit rough eh? lol im going to use the 150w hqi in my projector when i finally get it, they are a great bulb and last anywhere from 6000-12000hrs they output about 14000lm's im using a halogena light that puts out 2360lm's at the moment, its my test light and the picture is fully watchable at night or evenings not bad for only a 2360lm bulb, i put a small reflector on it last night out of a desk lamp and woaaa what a diff it made. The material of the reflector is that mirror aluminium try some of that its like mirror great stuff

Oh, so you have already retrofited a commercial projector with a different bulb? Yeah that guy is rough, and im not to happy with his results. So 2000 something lumens looks good? then 150w hqi will look great... or melt it... Is your projector lcd or dlp? I dont have mine yet, but its on its way. Im still not sure if i want the 150 or 250 watt hqi though. I guess 150 if you say 2000 somthing lumens did good. Can you post result pics? that would be great!!! and do you have specs for your projector?
Thanks Pizzi
Thanks for buying the projector from me Pizzi, and putting in a word. I've gotta say that it has brought a lot more interest to the InFocus now. If anyone is interested, please email me, and do leave your time zone, so I don't call you in the middle of the night, it just happened
.
Also, for the ones faithful to the DIY route, I am selling a 3M 9100
witha modified (enlarged) stage, so as to reveal the entire fresnel lens. I am also selling a 1024x768 LCD panel, which has a cut ribbon cable- I was unable to lengthen it- (about 23 wires in 1cm width). It is possible, but too tedious for me. Along with that, I have a $100 bi-convex Melles Griot lens- 100mm dia, 200mm focal length ( http://shop.mellesgriot.com/mlgriot...9&dept_idOpt=313&dept_id=313&pf_id=01+LDX+223 ) . For the lot, asking $400+shipping. Willing to sell individual parts as well.

poobear
heya poobear, nope i havnt got a comercial projector only one like me could wish lol the 2360lm's is what comes out of my test halogena light, that is the light at the bulb not the projector, the screen projected image however is not much less than a standard tv im not sure how manny lm's that would be but anyway these comercial projectors are not hard to retrofit just a matter of finding a bulb that will fit and the 150hqi bulb is small the burning arc is just 11mm on its own lol and that bulb puts out 14000lm"s im not sure the total length of the bulb i think 9cm or somthing ill have to look it up again. Another thing u could do that i saw on another site time back and dont ask me where it is cos i have lost it is the fact that u can get $70 bulb's for comercial projects but the bulb is for a different projector, all u need is the specs of the ballast and what it can run and maybe a small mod to a bracket or somthing for the light, i did see it done but i dont remember where.

Hmmm so what are you using the halogen light on? An ohp? Yeah i figured i could mod a different projectors bulb to fit mine but they still woudnt be very cheap. I guess a 150 or 175 should do the trick...
poobear
my projector is a home built one its about the size of a vcr it is lcd and the reso is 960/240 pix yeah crapy i know but its my first projector, the second will be a work of art with a ohp and the good old lcd desctop screen mounted it a false speaker enclosure so it looks like funiture , until u turn it on ofcourse lol the image will come out of a speaker port to hide what is inside. The optics in my projector are simple but work great, i have not much light loss from the optics, i predict im puting out somthing in the 200-300lm range so when i get my 14000lm hqi i predict somthing like 1200-2000lm range more than enough for me

Wow thats a cool idea, do you have any result pictures of what the outputed image looks like so far? I wonder if a commercial projector would put out he same amount of lumens..
poohbear
yeah go the 150w u shouldnt have any probs with it as in size or brightness, these bulbs realy pack a punch for their size and fully uv coated, i think when u go to 175w they are in the next size bracket like the size of the 250w and that would be abit big for a comercial projector one can imagine, u might be able to even fit one in your existing light in the projector if u can get the old one out of its reflector thats with a comcercial projector that is.Also in my projector i dont have a condensing lens yet either, basically cos i dont need one but when i get the hqi i will forsure as the burning arc is so small

na not yet lol but i should have soon, ive got a pile of pics of the projector though, it is done now and ive posted some pics of it unfinnished in the diy projector 2 thread, its just a matter of time to resize the new pics but they should be up in a day or two

i thought condensor lenses were meant to be used with bigger burning archs to make them smaller or to focus it into a smaller point. Yeah i might try to pry the bulb out of the fixture or "implant" a whole hqi setup. I wonder if there is a ballast in it, there must be if it has a metal halide bulb.

May I suggest something tho put the infocus into a bigger box with more padding if someone buys it. With normal shipping who knows what that thing will go thru and you dont want an expensive item like that broken. I got lucky I think.
