looking great!

managed to sand, stain, and poly my shelf.. here's the result..


view os screen from under the pj ( tv's on wheels so no big deal to move )


lastly, some room improvements to improve lighting conditions for daylight watching

Man that box is a beast. It looked big before now it looks like you can use it to shelter a family of four from a rain storm. Looks good my friend.

Is that oil of olay I see?

Keeps the skin soft and beatiful I use that also since the cold really dries my skin, and I'm in FL!!

Nice setup there...

Unfortunately my project is on hold since my wife consfiscated my LCD for her little Mac Mini. I just don't get Mac's.

haha good eye u got there.. takes a lot of work for me to look my best

Hey Comp, I just noticed you have the same curtains as I do. My woman made me take them down. Something about looking like a meth lab or was it a crack house. Oh well!

shh! the meth lab is my side business... but don't tell anyone!

time for a few updates.... my 2 92mm vantec stealth fans arrived a few days ago, got em installed





then spent the next 5 hours doing temperature measurements and watching LOTR return of the king.



dark scenes look pretty good



measured temps every 30 minutes or so using a digital meat thermometer..placed thermometer in air slot at center of screen. unfortunatly it is not long enough to reach the midpoint on the display, so temps are probably higher lower down the panel.. but the measurements i got look pretty good:

T = 0, Lamp on (degrees F): 68.9
T+5 min: 71.6
T+35 min: 78.6
T+65 min: 79.7
T+95 min: 81.6
T+125 min: 84.0
T+155 min: 82.0
T+185 min: 87.4
T+215 min: 87.2
T+245 min: 84.5
T+305 min: 83.3

so over a 5 hour period ( really the longest i imagine i'd be running this thing straight anyway ) my temps never exceeded 90 degrees F. i'm sure my temps are hotter towards the bottom of the screen but i think its safe to say my cooling setup is adequate ...and those stealths are nice and quiet

Yeah, I keep waiting for someone to have a police run in, because the Metal Halides put out a "just so" thermal and radiation signature that looks like theres a greenhouse going in a house....

My friend in the NG said they could do a thermal/radiation scan of my garage during the next manuvers...

Cant wait!

Why would they even have the equipment?
Well. Marijuana is Vermonts largest cash crop. The Feds estimate that over 15 tons of it get grown every year. And thats just the open fields. The national gaurd has a harvest program which they use each year to harvest between 3-6 tons each year. They use the radiative resonance of the plant as a source. Shows up like glowy green wool...Less than half of that is officially disposed of in the state each fall. They also do regular sweeps for non standard UV sources and abnormal heat blooms...

Just a tidbit...

Waaa!!! You beat me to it!

Seriously, though, great numbers! I've got three fans (two evercools and one 60mm Stealth) and I'm running at a steady 89/90 degrees. Looks like I'll be ordering my own 92mm Stealths now!

How noticable is fan noise during quiet dialogue scenes? Can you hear things in movies like wind and leaves rattling again?

yikes! maybe i'll shield my entire room in lexan to block the stray UV




well, the fans are not totally silent of course.. but the 2 in the box now are noticably more quiet that the single 92mm panaflo i borrowed out of my pc that i used to have in there.. the fan noise does not interfere much at all with movie watching now, though during very quiet scenes i can still hear them.. maybe i just need to beef up my sound system

today's the day... i'm making the leap into anti-glare freedom... wish me luck!

GOOD LUCK !!!

good luck man! let me know how it does, i might end up doing it also

update: ok i'm attempting to de-anti-glare my LCD using the water soak method.. its been soaking for almost 11 hours now and i think the ag is finally starting to loosen a bit... though as i peel it is rather brittle and end up breaking into tiny pieces.... perhaps i need to let it soak longer.. i think i'll leave it the rest of the night and try again in the morning..

I was thinking of doing the rag method too in a few days. Got my fingers, and toes, crossed for you!

Did you tape the edges when pulling it up?

*&#*! :angry:

so i get up this morning ready to see is the ag is easier to peel off.. and what do i see? the paper towel was totally dried out... so my guess its back to square one with this process. we'll see what happens...

wow.. what a nightmare... finshed getting the anti-glare of my panel very early this morning ( or very late last night depending on how you want to look at it ) basically i had the thing under pretty heavy soak for about 16 hours ( after my initial 12+ soak dried up entirely while i was sleeping ) and still had some stuggle taking the ag film off.... it would peel very easily at times but other times it would tear and i ended up having to peel it off in pieces and go very slowly.. if anyone else is planning on the water soak method for an l72s, bring a LOT of patience because the ag does not give up without a heck of a fight.

good news is after a long hard struggle i managed to get about 98% of it off and what is left around the edges ( the most stubborn areas ) isn't part of the pixel surface.. my plan is to allow to dry all day today just to be on the safe side, reinstall tonight, pray to god and flip the switch.

we'll see what happens...

ps. pics to follow once i get them downloaded.

wow i hope it works!

yeah me too... i REALLY hope i didn't mess up my panel.

was just thinking.. i wonder who'll be first to post a xbox360 screenshot

whew.. it was a stuggle but i managed to get my ag off without destroying my panel

here's my frensel / LCD assembly removed from my pj


closeup of the enemy..


LCD removed and electronics masked.


paper towels laid down and soaked


just to recap, i only had 1 layer of paper towel laid down and it ended up drying out while i was asleep, after 12+ hours of soaking too. so the next day i had to reapply and start the clock all over again.

after the resoak, i was finally able to start getting the ag off.



the soak could have gone better but after being VERY careful peeling the film off and going very slowing ( it did not come off "like butter" like others' ) the panel is just about ag free.


only had a small amount of residue left over while was easy to get off with a little alcohol. i was not able to get all of the ag off in one piece which it partly why it took forever to remove. here's one of the larger pieces held up to a light.


most of the large chunks removed.


around 5 am i finally got the last bits removed so i was a little punchy...

giving the ag what it deserves!

But what about the LCD? Is it still alive?!

Congrats on your patience through this!

Yes, Dweezilkid, it's still alive.
Everybody has to be a smart alec every now and then.

here's the last little bit of ag that i could not get off, it really is not an issue for me since its out of the field of view.



not-so-new but definatly improved panel back in its home.


i was quite concerned about the panel still working afterwards because on of the corners was slightly damaged while trying to get the ag clear of the polarizer.

i put the box back together, crossed my fingers, and flipped the switch. the first thing i noticed with the top off was the light hitting the triplet was much crisper that it was before.. i put the top back on, threw in the episode 3 dvd and this is what i got..


yoda is such a little badass



i'm very pleased with the result of the ag removal though i didn't see the increase in brightness ppl talk about. the picture is definately shaper when focused and the colors are improved.

dweez,

yup, it made it though its ordeal relatively unscathed.. i ended up with a tiny tear in the polar in the lower corner as a result of trying to pry the ag up.. when fullscreen is displayed, there is a tiny sliver of white that always shows up now where the polar was damaged... not a big issue though since its at the very edge..

EDIT: forgot to mention, i'm also able to see the fresnel grooves on the screen now.. i know many others had them show up as well, i'll re-adjust my distances and hopefully that'll clean it up.. is there any way to tell if they are the read fresnel or front fresnel gooves?

Sweet!

Glad to hear the operation was a success. The shots look great! I've still got a little residue on an edge too -- doesn't show up in widescreen movies either.

I'll revise my earlier statements about brightness -- I think my "perceived" brightness is higher since the contrast, colors, and sharpness are all so much better. Though I think it helped a little.

congrats on the ag, just finished mine too , its an older hyundai panel I believe(17") do you know the lcd panel model number itself?(as opposed to the LCD model(which I see is the 72s) it usually on the backlight or thereabouts, mine looks fairly similar, though an older model.... ag stripped fine on mine except a couple of edges...

hmm... dunno if i still have those parts laying around.. i'll have to check on that.

time for a few before / after screenshots of my anti-glare removal.

top screen is ag removed. bottom is ag in place.








just starting to get introduced to the magic of ffdshow.. this program is awesome!

screenshot comparison with ag removed, top is ffdshow enabled, bottom is disabled.
*disclaimer: my machine is not powerful enough (yet) to run this quality at full framerate, the pic is for comparison only*

Odd... i prefer most of the lower photos (not counting the ffdshow).

What does the damage look like when projected? thats a real shame you can only use widescreen media.

Maybe he got them backwards, as the way the images look, the lower ones also look better to me.

I'd say they'll be the rear. My collimating fres is now ~35mm from the LCD and I have no evidence of fres rings whatsoever.

The images arent switched around. I think many of us are looking for brighter images. If you look carefully at each image you can tell the difference, color is more vivid, much crispier, and shadow detail has improved a great deal. A good example is the third photo, the image with some sort of spike and finger in darkness, not really sure what movie thats from but anyway look at the color of the finger, its very true to color. Also look at the light hitting the rock? thats what I call some natural light. The before photo looks blue. I think a/g removal gives us better colors and better detail as previously stated. Most of us are always looking for that boost in brightness so thats the first thing we look for.

brutuz,

the damage basically looks like a small sliver of white when projected... even if the image is blue or red or black or whatever, it always shows up as white... i'll get a pic up of it soon, its not that bad really.. 4:3 content is still very watchable but its not 100% perfect anymore... only about 98.5%

the images are correct. the top ones are with the ag removed... you can tell the lower images look a little washed out relative to the upper images also in some of the pics, more detail is seen in the upper pic, for example the smegol pic u can see more detail in the hair clothes in the upper pic vs. the lower. as far as brightness goes i dont think the images are really any brighter, just better colors and contrast.

You're right, i couldnt see it until i used a CRT. Man the LCD in my projecter might be better then the LCD i use on my computer!

thats the way it should be

Awesome comparison shots! I hope to be getting some like these up on my PLOG soon.

The post a/g removal shots most certainly have better color saturation/contrast, but it is not as dramatic as in some of the shots I have seen. It could certainly have to do with the inaccuracies of screenshots in general, I am finding that myself. It is very hard to capture color differentials in screenshots. In person, my picture looks far better post a/g-strip than my screenshots suggest.

My other question is did you change your video driver settings? It does seem like you have your post a/g-strip contrast (white level) set a bit lower. I can see no other reason why the apparent brightness of the projection should DECREASE after a/g strip ?

in thinking about that the other day i relaized i may not have even had the same camera shutter settings for the before and after pics ( i know... REAL scientific huh? ) plus i found some picture settings i could play with in my dvd software that i was messing around with.... so much for an apples to apples comparison.

my new issue: did some lens re-aligning other day but light is still hitting triplet off-center and not allowing for me to get complete focus across the entire screen. ( its maybe 95% there, but i'm picky ) i think i'm going to have to build in some horitontal adjustment for the triplet itself.. -sigh- time to break out the rotary tool again...

Very nice projector, you mention that the light was hitting the triplet off center, I noticed a few pages ago in your plog when you used the Laser and the laser hit slightly to the left of the triplet. And I dont remember if you had said you resolved that, and now your getting to that.
Good luck on getting the horizontal adjustment bracket for your triplet.

The ag removed shots are BIG improvement in contrast! WoW! Can't wait to remove that AG on my WUXGA.

thx, fly cant wait to see the wuxga in action! just read up on everyone else's experiances before going at the antiglare to be safe!

Yea, haha hehehe, waiting for someone to take the leap first hopefully. Maybee it will be me hell I duuno. The whole process seems very safe as long as the Ag layer is permeable.

someones got to be the pioneer right? why not you?

damn...that never occurred to me....jeez , I've recut my frontpiece 3 times now.... thanx for the idea... I can put h/v alignment in it just like for the bulb..sigh... I can't believe that never occurred to me

"Adjustability. Adjustability. Adjustability. These three hallowed words reverently dictate what you ought to be, what you can be, what you will be."


managed to widen the triplet hole a bit horizontally but it still looks like a chunk of the arc is hitting the edge.. may have to widen it a little bit more to slide triplet over

still not 100% satisfied with my focusing "mechanism" either.. one of these days i may pull the whole front of the box off and start over...
