but where am i wrong? why does the lfuorex succeed with me while being completely out of the range of theories that are proclaimed here..... i really would like to know. Why is it that with brute power and the 2 fluorexes some one and a half inch away from one fresnel and another inch from the lcd panel followed by one inch of spacing and than a delta IV lens the picture projected is more than descent! i would really want to say pretty darn good!
i read here of washing colors away, daze, haze, screen door effect, those things do not seem to exist in this set up ? why is that?

the 16/9 i get by pulling my box back , when playing this format so that the projected picure covers the screen completely ( i made it in 16/9 format from the beginning) again, something so easy........ i have no special lcd 16/9 but i know that when playing a widescreen dvd on my extremely cheap Mintek dvd player trhough the lcd, i get a widescreen result that does give me the whole screen.

see this are some of the things that bother me ..
further more Nobody has answered my question on 16/9 being a format completely against nature and mankind... ===sighhhhhhhh===
i really wish someone would help me understand why when i do something completely wrong, the results are positive! ! ! ! !

Hello

Personally, without research at the moment, I think that the reason they chose 16x9 is because it's a round number. Theres no decimals it's jut a flat number.

As for your setup, did you ever post pictures of it? I can't remember. If it's a cheap setup and it works, I'd love to see the results.

Nothing could be more natural....

16:9 = (4:3) ^ 2

No one said you can tuse those bulbs. THe point is they arent very good. I have one here. It says its 8000 lumens. But it was half as bright as my old halogen 90watt bulb which is only 1,200 lumens. See the thing there. The higher lumens doesnt mean brighter picture. Its cause of how the bulb is. Now I got a picture with it, just that I had seen it with other bulb first . Two of those would have been as bright as my one halogen. Def. not a good solution so I moved on. Went to MH and ther is no going back now. I love the brightness and how you can control the light. This is because its more of a poit light source. Like the halo vs. flourex. Its all personal preference. I believe you get image with it. But I'm sure it woudlnt be as bright as a MH seeing how I have on eof both and tried both. Seeing is believeing. Have you seen a MH do its magic to compare to your setup. It will change your mind Im sure of it....

By the way heres more proof of MH. With my halogen when I turned on the lights the image disapeared. BUT with the MH it not only doesnt vanish it is extreemly watchable with even the edges of screen bright. Dang near my little tv brightness when reflected off silver screen. I'm running a 13" tv below the screen to adjust color and compare brightness, its helped alot so far!

Yes but there is no real pics of it working though either. I cheked his site. Its the same guy from ebay. Plus did you see his LCD projector scam....its the same as what we are building but all tidy up in a metal case.for the low low price of $800.00 Ya O.K> let me get my wallet. Tya, I can get a 1 year old sony lcd for that. I saw a DLP for $1500.00

I liked his TV projector only $179 and giving

"As good a picture as a $3000 projector"

You believe that. ??

Its a scam. He is just looking for people to suck them in with a glossy website.

Good to remind people about things like this.

remp, read my posts at "very simple projection plans"!
i wrote how to put fresnels, its the same thing as they did, but here nobody wont to try it!
nobody here experiments, everybody is just talking and talking and talking!

[Tinker]

I did try it, the edges were blurry but I thought it was due to the first fres. not covering the hole screen of course. None the less Im not spending $30 on a fres. big enuff to try it when I have a perfectly good working 100x brighter lcd projetor. I do things, not just talk-so I resent that staitment personally. If you even knew how much experimenting I have done with this stuff in the past month alone you wouldnt have even said that. Some of us are "do'ers" but we wait untill we have solid #'s and figures to go by. Significant gains instead of just mindlessdribble. It takes time and patience. Please be more leanient towards those who only "theorise" and not do these tests. Having a theory to prove or disprove is 50% of what a experiment is about. ONLY After that it becomes fact or fiction. Lets not forget that. Ideas are hard to come by and the more minds thinking the greater the input.

That is a terrible thing to say. You are being very disrespetful to a lot of people.

Open your eye then you see hundreds of guys experimenting, suggesting improvememts, suggesting places to find items, supply drawings of setups, posting pictures of progress and finished projectors, helping other guys get pinouts for connecting cables, posting links to helpful info, trying out how to make reflectors, trying out different lighting systems, and many other advances.

For your information many succesful large screen projectors have been made and are in the process of being made.

Guys here co-operate with each other. Someone has a problem and someone else or several others will post a helpful reply. Have you not noticed that.

As far as your comments that no one is interested in trying your suggestion maybe they are not interested. I tried the idea of putting lens in front of a Tv years ago but found it worked but not very good so moved on to a proper projector.

Your comments are unsuitable to say that we dont do any experimenting but just talk, talk, talk, I have asked the moderators to put you in the sin bin for two weeks starting now.
