I'm still using Windvd which sucks but I can't get my sound working in any thing else. The dvd players are using AC3 which I don't have as an output on my sound card. I don't know where the settings are in windows. I have used XP alot too.

Santa comming.

That is a REAL santa too look at that beard.

So that's what you look like:)

an a merry christmas to you and yours AV! but the real question we want to know thr answer is how does santa keep from catching his beard on fire when he adjusts the lamp in the pj?

In the old days we just soaked it in beer before we went out.


I'm doing some fine tuning to the picture, mainly adjusting the power level to the lamp. The main reason for this is the PJ always makes a cooking wood smell when it is on high power setting. When out side I don't notes it but inside after some time it a little bothersome. On the low power setting is fine but the color is way off.

I changed the caps around to make the low power setting higher and the high power setting lower.

I didn't take readings but low should be 850 watts now and high about 1050 or so.

She They say you can dim the lamps but you should bring them up to full power for a few before reducing the power, so that’s what I do. They also say that it does not increase lamp life which I don't believe.


My blacks got a lot better with the lower power setting but the reds are not as good. It didn't mater if I raised the red level either the red just moved a little toward the orange side. It still was good just not perfect.

The hot pixals are just CCD noise. I don't know what happend to my glowies they just went away?? Maybe mu reflector fell off?


I have had a screen saver for Christmas running and you don't really notices how nice it looks until you see the big screen with it.

She looks like my wife, except she's blond tall, tan and thin.

I did a high low test too but with the camera on auto you might not see the color shift.

A few more the first is at 850 watts and the second is high power.

In this screen saver the snow is falling but the people are still.

I also did a have some new screen material so I placed some BO cloth on the top. The new stuf is the mmain screen.

and the screen. It is just hung from a wire on the roof. Rember my pj is supose to be out side.

The screen materical is dirt cheep at $2.00 a yard. It is a vary white plastic PVC. You can do a whole 60 x 120 screen for less than $10 and it looks great.

hey your projector looks pretty bright. this is making me wonder about the specifications that the commercial projectors put out.

i just bought to commercial projectors and i want to test out if the ansi is really as high as theysay

one projector is the infocus lp500 rated 2000 ansi

the other is one from mitsubishi rated at 1000ansi

i think yours may be as bright

Any DLP will be 2/3 brighter than a single LCD system before you do any thing else. The eye trick of only showing one color at a time pays off big time.

I hate flicker and don't want any rainbow effect. I think a three color panel has an advantage here.

There is an advantage of a larger LCD with a larger area for the polarizer and a larger area for the color filters.

I don't want to say that my PJ is brighter than a 2000 ANSI PJ but it will be nice to see a comparison after the 2000 ANSI is setup for a good picture.


The final question is how good of an image can you make and at what cost.

The HMI lamps make some of the best color, better than the HQI, slightly better than a UHP and not quite as good as Xenon. They are not too much money at around $50 to $120 on eBay.

There is some guy on one of the threads talking about how most of the new commercial PJ just blow the DIY away. I have seen a few and I don't see much difference in picture quality.

The other day at my sisters house the neighbor set up a front yard screen with one of the small “corporate” PJ it looked so bad I had to leave!

We do need to watch how much we spend though. I saw a nice 1280 x 720 PJ at COSCTO for $999 that looked fine and had great specks.

I run most of the movies in Pan & Scan mode so I an displaying more than 720 in the horizontal plane more like 900 lines. A wider LCD would help.

At least I will not ever have to buy a $60 made in China lamp for $400.00

Let me know when you get your PJ’s. Do you have a LUX meter?

Thats a great picture.

yeah im one of the people that ordered from ywh from diyaudio.

once i actually recieve the bulb. which wont be for another 2-3 weeks. i will show some pics. um i dont have a lux meter. how much do they run.

It’s true that a DIY LCD will waste 2/3rds of the light available because of the sub pixels, RGB. And that it will also waste light to the polarizes. A commercial 3 LCD unit won’t have the sub pixel losses but still wastes light at the polarizes. But a single chip DLP still suffers light loss from the color wheel. At any one time there will only be one color available so if it has 3 colors it will still be wasting 2/3rds of the light.
This it just my opinion but I think that a LCD monitor like we use may have a larger aperture size compared to the extremely small LCD used in commercial projectors. So this may offset some of the RGB losses. And the 3 LCD optics have to pass though a lot more surfaces.
Each tech has its own pros and cons and the differences in light output may not be as great as you would think.

DJ

A/V,

Awesome pictures! Very Nice Clarity! Your choice of screen material looks like a great choice.

So just double checking, is the white plastic PCV screen material you mention the same as the BO cloth at Joann Fabrics? If not, where did you purchase it?

Cheers!

Fulcrum

Arizona, where did you buy this material and what is it called? As you saw in my thread I am looking for a new screen material.

P.S. I will answer your question in my thread, the next time i post in it, after I get my new screen made

Both screen material is nylon thread with PVC plastic on top. The guy said it was used for gulf bags I think it is called poly canvas. I took some closer pictures of the material. On the left if the cheep stuffs the stuff on the right is the $8.00 yard Polly canvas. The cheep $2.00 a yard stuff I have never seen anywhere else. It is an overstock and he has 15,000 yards.

If you guys like it I might buy a whole roll and sell it for the $2.00 yard price. The roll is 60" so a whole screen ( 60" x 110") is about $8.00 + shipping.

There is a pattern embossed on it and the side shown is slightly more embossed. This is the side I'm using. Some light does pass through the screen( with my PJ ) with either material. So it is not 100% black out.

I have about 32' so if any one want's to give it a try let me know.

I found an article from X-bit labs that takes a in-depth look into how to judge LCD panels.

I have read this website for years and they always have great reviews and articles.


http://www.xbitlabs.com/articles/other/dis...parameters.html

I still have the 2000 watt HQI lamp setup in the test box. I striped the antiglare off the 18" LCD today. It had antiglare on both sides.

I didn't like the way the HQI looked before the antiglare strip, it looked washed out, now it looks much better and all the colors are much deeper, so now I like the bulb.

I didn't adjust the lamp so a lot of light was missing the triplet.

A few screen shots and one with a 500 watt lamp next to the screen. I'm geting 230 lumen in the middle with no reflector or condenser and tha lamp running at around 2200 watts.

It look better in real life, for the few seconds that I blocked the stray light the color and contrast of the lamp was good.


I don't have any thing else to do to my PJ except paint so I might have to retire this thread and go to the old folks home over in the completed PJ plog.


I now like the 2k system so I might throw a folded box together I have all the parts.

How is the lcd secured from poping out towards for instance? Whey did you not use the original aluminium frame?

In the first picture you can see the whole slead. There is four black strips of 1/4" hardboard that screw down on top of the LCD.

In the other picture you can see unpainted MDF frame with the retaining strips removed. I didn't pull the LCD all the way out just so I would not mess with the FFC conectors mor than I have too.

I may treat the side of the panel with black tape or paint to help stop the edge bleed glowies.

My brother in-law is now looking at buying a commercial PJ So I was looking at some reviews of some 1080p PJ and I found that even at $4,000 they are not always much brighter than my PJ. I'm getting around 450 lumens.

The other PJ’s.

1080p Shootout:
Mitsubishi HC5000, Optoma HD81,
Panasonic PT-AE1000U, Sony VPL-VW50

Lumen Output

These readings describe video optimized ANSI lumen in high lamp mode with zoom in

wide angle position. Subtract zoom lens factor if lens is in maximum telephoto position (Note:

The reason for the radical difference in zoom lens factors is that lumen variances on a given

projector generally correlate to the zoom range of the lens, which differs greatly among these

models):

1. Optoma: 655 lumens, -6% at max telephoto
2. Mitsubishi: 532 lumens, -24% at max telephoto
3. Panasonic: 500 lumens, -45% at max telephoto
4. Sony: 404 lumens, -25% at max telephoto


Current estimated street prices as of this writing:

1. Panasonic: $4,000
2. Mitsubishi: $4,500
3. Sony: $4,800
4. Optoma: $6,800

Well it looks like I'm bumping my own plog but I'm really just announcing the end of winter and the start of summer! (We don't get spring in Arizona sometimes)

It was over 85 deg today and a nice 74 deg tonight so the Drive In is open!

It was Scooby Doo again but the kids said they loved it. The thing about all the Scooby movies is they are all 4/3 so the screen is way to small but the kids don’t care if some of it id framed on the rafters.

I still love the color of the MHI lamp and the LG 17" LCD. I hope my new 15" UXGA is as good.

I'm still working on a new screen I have about 190" x 72" of new stark white vinyl screen that I might sell( sen a PM if you need some screen) to get a 92" x 180" of not so white vinyl. If you want a large screen I will sell it at a loss. It is better than BO cloth.

whats the charge at the gate?
p.s. i envy you

The charge is the same everywhere 1 cold one I'm cheep.

I'm going to spend some time wraping up some photos to put the megawatt in the Completed Projects PJ plog before I strip it apart and go the the LG UXGA panel. ( I looked back on the plog and there is not many good pictures of the thing.)

The first controler was not made to run the LG UXGA 1600x1200 panel it but the second might , If the plug fits.

Some of the new guys might not have seen what a high power rig looks like.

I felt dim the other night and bought a CDM SA-150 for cheep. I don't know why? It would make a good room light. ( I'm not kidding if it looks good and dims well I may us it. It should make a lot better light than the CFL I have now.)

I found a 65 watt CFL the other day it's like supper sized. Works OK but not the best color it's a little orange

I have way over a $100 trying to find CFL lamps that look worth a poop.

Thanks for posting that, i was just going to dig thru the megawatt plog to check out your cooling system.
is it (3 )120mm blowers on the bottom of your PJ?

The LCD has 3 120mm that suck from the front of the PJ then go under the LCD tray then up between the LCD and first fresnel and mostly out the top three holes. Some air goes to the back of the PJ.

The back of the PJ has two 80mm fans on the light box which has it own duct out the side so it sucks the air from the front of the PJ and out the side blow hole. This air is really hot like 180deg.

There is one small hole to let the hot air out of a dead spot right above the light box.

The two ballast in the bottom box have 1 120mm fan first blowing right on the 600 watt ballast and then the 400 watt balllast is in front of the air exit.

i have really got to get a higher wattage bulb with a smaller arc.......what bulb do you think you would recommend out of the ones you have tried.....i would really like a 1000 to 1200 watt bulb, but i dont know........i want brighter than what i have.....you are the lamp expert, so who better to ask than you?

The new Spiderman 3 is out and My wife is trying to get meint the movie theater but I lust want to watch it outside when it comes out.

I know on my setup, an upconverted to 1080i looks good, but HD 1080i looks amazingly better.

I now have three sun burn marks on my LCD from leaving my PJ facing the east at night only to have the rising sun burn a mark in the LCD.

I de-focused the triplet thinking that it woud be safe but it is not.

I am done with the PJ for now but I need to replace the LCD and I may be going to a WUXGA. The LG UXGA did not work with the carpow controller but I may have killed the panel by connecting the wrong controller so at this point no one knows for sure if a UXGA will work with the carpow WUXGA controller. It should work and would be about $100 less for the panel.

I am going to remove the lexan for some more lux soon because I don't need to protect my LCD any more because it is almost toast right now. The burns are not in the main viewing area.

In the long run I will build a new box for the WUXGA mainly to make it easier to move around. The old box I just may re-use the 17" and try out the 2000 watt HQI just for fun.

Isnt that the second panel sacrificed to the sun? Maybe a plastic bowl or something could be used for a cover.

I have a Blu-Ray SpiderMan 3 demo disc and it looks like crap. I'm almost 100% positive it is in standard Dvd definition.

Maybe they did a terrible job on the Hd Spiderman demos, it happens.

First panel, I have yet to kill a good panel if you don't count the sun. The third burn is a strip in the top middle edge thats hard to see. I can still kill it yet

John: The panel is just a 17" so it is the main limit. The color looks sligtly better with a HD but the PC is choking too, droping frames and skiping sound.

The last video card I bought, the NIVIDA 6200A was stolen for the kids PC (to play Lego Star Wars again and again) The PC has onboard video with a SIS uni-chrome chip. It does have accerlation for standard DVD and looks fine with good sharp video but nothing for HD.

Wallmart will be selling HD DVD soon for about $179 (they bought 3 million drives for $150 each) this winter so HD drives will be almost cheep.

wuxga panels can be had on ebay for $100-150 fairly easily, and should work with the carpow controller, so i'm not sure you'll save all that much using a uxga panel.

can't wait until you replace the LCD... then we'll get to see the 2000w'er in action !




Sam's Club (walmart warehouse "club") has been selling the xbox360 HDDVD drive for $180, which can be used with windowsXP. I think anyDVDHD gets around problems with downsampling too...

I bought a LG UXGA on eBay 3 months ago after Carpow said the Genesis chipset controller would run it. I got the controller from John a few weeks later but the connecting cable was wrong but I found one that "Fit" and tried it. Nothing.

Then I tried my LG controller from my 17" LCD and the cable fit and it did make lots of strange lines on the LCD but it was crappie.

I then noticed the chips on the LG panel were getting really hot so I pulled the plug.

I then looked up the Genesis chip on the net and the chip on the board does not support 1600x1200 so Carpow was wrong. I wish people who sell things like controllers would read the specs before telling me they will work. If he said "I don't Know” I would have looked up the chip first before I bought the panel and the controller.

$200 later I sent the panel to John to test with the WUXGA controller but there was no glory. He said it did nothing.

I could have killed the panel or it could have been dead when I got it or the WUXGA controller has the wrong cable or the controller just won’t run the UXGA.

I just like the LG panels better than the Samsungs because the antiglare strips better most of the time but now John has a LG WUXGA coming in for only $200 more.

At least it should work with the WUXGA controller.

I liked the idea of the 15" UXGA just because it was a nice throw for the 18" triplet and the extra rez should be enough for most everyone and if it worked would be $100 less than the WUXGA setup.

Well I tried.

My PM from Carpow.

I have a LG UXGA LCD (LP150U1 (A2)that I would like to try out one of your controlers on. Which one do you think would be the best?

Thanks

"the DVI 5221 controller can be work fine"

Here is an auction for an 15.4" LG wuxga for $180 shipped. (Here) This one is pretty decently priced, but keep your eye's peeled and you can find these for $100-150 at times... (take this with a grain of salt too because unless someone tries it, no one knows how this panel will react to the wuxga controller you have) ... although most using the G2A and carpow(johnzo) controller seem to be switching to other 15.4" wuxga panels without trouble... AFAIK...

As far as throw is concerned, a 15.4" panel run at 1080 will only use 15" of active area (16:9 ratio), so the thow calc's will be the same as for a 15" uxga, just the aspect ratio is different 15" (5:4) for the uxga and 15" (16:9) for the wuxga run in 1080 mode. (unless the scaling isn't correct, then you're left with 15.4" (16:10) for the throw calculations.

I hear ya on the controllers. It's a real gamble when using different panels with controllers. Sorry you spent so much with nothing to show for it (yet ?!)...

Hope things work out for the best... and with minimal additional fundage...

gs

Yea I'm suprised you didn't toast the Lcd.

It's not just a matter of plug and pray. You have to have the datasheet for the controller and the Lcd. Then you have to match the Lvds pinouts from the controller to the Lcd. And then you have to program the controller to output the proper resolution and timings. It's quite complicated.

I havent spent that much and John is going to apply the $100 toward the new controller. I knew I might Kill the LCD I was just hopeing........


Grab a $100 bill and light one end.

If you could go to a (EDIT) 1600x1200 LCD with a controler for $200 would you try?

It may still work but I will wait untill I have a controller in hand with a chip # and conector.

Um... I assume you meant 1600x1200... If I had a SCREEN that did 16000x1200 that'd be really skinny...
Then again, Circuit City (I think) had a DLP projector listed this week in their add that did 1024x7686. Tall and skinny... Hmm... Maybe it's based on the same controller...
