quick question....for ace3000_1 or anybody else who knows
do you know if those little lcd screens used for the original playstation can be used in a setup similar to yours.....they're relatively cheap...have inputs already on them....(for those of us not inclined to get into soldering)....are all lcd's backlit?.....if so then i guess these would work with a decent light source.....i'm talking about those little 5 or 7 inch screens that make the original playatation into a little portable gaming system.......they're made by several diffrent companies......
i love your project so far and have read the entire thread over the past few days.....didn't think that thread was the right place for this question as it doesn't pertain to your particular project.......keep up the good work |

heya low, thanks for the nice words, the 5inch ps lcd's are fine, infact i think there is a modd where u can run vga in them from memory, try a search on the net looking for that partiular lcd and im sure u will find it, now the only problem with those small lcds is the fact the reso is abit too low, they are good upto about 60inches then they become abit too pixelated for close veiwing, they arent bad though to fool around with for your first projector, and those lcds are quite rigid too, they look fine on tv signals but it will depend on how far u sit from the projected image, if u cvan find one with a lcd thats made by sharp, they are the brightest lcds and will give u a nice and bright image, also the contrast on these are abit too low too but once again not bad for tv and video veiwing, all lcd's are backlit, without a backlight we wouldnt be able to see the image.

thanx ace.....
i might try one of these for my first attempt......feel alot better taking apart a $30 lcd than a $200 lcd.....
i bought 2 of those fresnel lenses from one of those guys on ebay claiming the 150" from your tv....tried it for a bit and it didn't work too well.....are these the same fresnel you're using....they're 4X i think
and when you get your plans finalized do you have a price set for them yet?....i might want a set for ideas......
keep up the good work |

Ya they would work but the focal on those are quite long so it would make your project bigger then it should have to be, they arent the same frensels however but very much the same, the plans will be $45, they arent just a quick set of drawings put into a file, they will be very comprohensive and acurate in cad format with a guide to each plan page telling u a few hints and tips on making the object on that certain plan page and where it will go, all things will be draw up in the plans, it is alot of work but the better the plan the better it is for u guys to make also getting your monies worth, there are heaps of ideas in the plans most of it can be used in a projector very similar in design and not just in my design, what makes it easy for u guys is that u will have a plan to work from, u build the item and it will work at the end of it, with me its abit diff, i come out with the ideas and design the ******* thing with manny hrs work lol, i only wish others would publish some plans like my projector so that one day i could take the easy route lol, the plans are numbered and asigned to a numberd guide, u cant go wrong in building it i can asure u.

thanx again man.........
i'll probably give it a shot with the lenses i have and one of those lcd's....just to get a simple basic hands on knowledge before spending larger amounts of cash......
good idea on the plans......if i can scrounge up a quick $45 i might take a set.....
as for a final focusing lense.....do you know of any cheap ones....that's about the only other thing i would need to buy....everything else i plan to build or use exsisting supplies here at the house........ |

.........i'm looking on ebay but this is what i'm looking at......they are made by several diffrent companies but i think they are all nearly the same.... some may be a little better quality than others.....i bid on one on ebay for $30 and lost to another bidder who had bid $30 earlier than i did....if i had gone $31 i would have gotten it.....you can buy them now on ebay for as little as $49.95 but that's almost more than i want to spend on something i'm going to take apart, for my first attempt anyway....
when i do get one i'll take pics and keep tabs on my progress as i go
ace.......a shorter focal point will be better...it means i won't have to have as big of a projector unit.....right? |

that one on the link is made by sony....it's more expensive than the others i've seen.......by a good bit.......there's one by a company called Intec......they're being sold on eBay for $42.99 and up......they may also have a website....however it's only a 4" screen as compared to 5" on some of the others......

Just some more info on the various PSX screens available, from someone who also started using a PSX screen. I know there are at least 3 different brands of screen available: Sony, Interact, and Intec. The first 2 are 5" screens, while (as was mentioned before) the Intec is a 4" screen.
My first attempt was using an Interact screen. There are ribbon cables on 3 of the 4 sides. The cables on the top and bottom are fairly easily extended (not the rigid flat plastic type, more IDE-ish) if you're handy with a soldering iron. The cables on the side are the rigid flat kind. I succeeded in extending the top and bottom cables. You can then fold the controller board 90-degrees to the side, if you are careful. I, however, managed to crack part of the rigid cable on the side when I was mounting the assembly (after all of the hard work was done). It still works, except for a stripe about 1" wide running the width of the screen. This screen does have s-video input as well.
I purchased an Intec next. I then realized it was a 4" screen and not 5", so I have not opened it up to see what the inside is like. I do not believe it has s-video input, but as I said, I never messed with it that much, so I could be wrong.
After breaking the Interact, and ending up with a 4" Intec, I moved onto the Sony. I did not know about the VGA mod at the time, so I am just using the standard composite input. There is actually a bit of an issue with this because Sony does not include a standard RCA connector on the screen. Instead, it is a modified 3.5mm headphone jack that has stereo audio and the video all in one. You can either purchase the cable from Sony or on eBay (~$10 I believe), or you can just solder a connector directly to the board where the input jack splits the video off (the route I went). There is only 1 ribbon cable on the Sony, and you can fold the controller board 90-degrees out of the way easily. The resolution of the Sony is better than the Interact or Intec as well.
As ace mentioned, these screens are better suited for smaller projections. I currently have mine doing a 90" diagonal, and the pixelation is noticeable from 12' away. The contrast is also a bit low, although some of that is due to my light engine. I only use it for TV and DVD, so I have no idea how video games would look.
As a final note, I didn't pay more than $50 (including shipping) for any of the screens. I got the Sony for $40. Just watch eBay and be patient. |

| Lowjacker |
thanx for the info cohort........
that's the exact kind of info i've been wondering about.....
i'm watchin' ebay all the time and almost got an intec screen, but i might hold out for a decent priced sony if there that much better and easier to work with......
i plan on making my light engine as bright as possible without getting way overboard or washing out the image......
i'll keep my eyes on the sony's.....
if any of you see lowjacker bidding on one please please don't snipe me.....i would appreciate it |

Hi,
I've got a problem. I have a lcd screen, it's called screen station from bigben.
but it has no input, so I opened it and take out the screen.
But how can I make an input now ? (foto: http://www.free.pages.at/dieter3000/lcd.jpg )
sorry for my english, I'm german
please help me! thanks !!! |
|
|
| Lowjacker |
that answer would best be left to ace or another veteran of the DIY arena.......
i'm guessing that all you need to do is recognize the input wires and power wires....seperate them and solder on some adapters....like an s-video or rca jacks.......i may be wrong....and probably am.......but that's why i'm still a newbie as well...........
good luck

the first post here is a reply i had to another post in that thread......
Lowjacker []
diyAudio Member
aidan.....
many of us are waiting for ace's plans to be completed......
when he's done with them we can all utilize his knowledge plus add our own touches to the projects making them based on his ideas but not exact replicas......
besides....i'm not sure who, if their a true DIY'er, wants a projector EXACTLY like anybody elses.......this is definately not a cut on ace....by any means.....but even if I use his plans i don't want an exact copy of his projector.......i want to pick his ideas apart a little and use them how i need to......i plan on using a 5" screen to begin with so right off the bat his 7" screen plans will need to be adjusted......
that's the best thing about getting his plans.......he comes on this board often enough that you can still pick his brain and ask questions even after you buy them........
that's a big plus in my book.........
WELL ACE..........................WE'RE WAITING.......................
ace3000_1 []
LOL yeah ok ok its getting there, and yeah, even though im making plans for an exact replica u can also make your own from the plans, the light engine and lcd unit is the most important, this can be placed in any designed box u want, even with or without a mirror, the possibilities are endless, put it this way i could have made over 20 designs on the projector im making now with my base point, but the one i chose for the look is the one u see in my thread.
lowjacker after ive done my plans i could draw u up one for the 5inch lcd if u want, it will use the same parts.

ACE, the more i read about people saying that the 5" screens don't have a good enough resolution is kinda making me wonder if using a 5" would even be worth it.......should i hold out for the 7" or are the 5" good enough and people are just that picky with their images?.... i want to use mine with all types of video from dvd's to video games and want a good pic......also...are RCA inputs really that bad.....the 5" screens that i'm looking at are appealing to me because they already have the RCA jacks on them.....i was just going to leave the unit completely in tact other than customizing for the light source and all...... also one more thing......do i want to place one fresnel before the screen and one after or just one before to get the light to cover the whole screen evenly....... wouldn't one after the screen invert the image or is that what you want and another lense after the second fresnel reverts the image upright again?.............
man i'm a newb.............

Heya buddy, best to get a 7inch, they are wide screen and have 3x the amount of pixels, beleive me the 5inch is realy only good for fooling around with, the 7inch is much better, it has 3 inputs and has alot more features, the image quality is way way better especially in xga on the vga input, svga is hell clear on the vga input, the rca is fine but it just wont be as clear as the vga, colours also look abit muddy on the rca.
The best way for an even light and for a bright output is to have 2 frensels behind the lcd, trust me ive tried everything with this monitor with all kinds of frensels. The image doesnt get inverted with the frensel, the projection lens inverts the image upside down, an easy fix for this is to either run your computer to set the image upside down and back to front, use a mirror, or set the lcd to run backwards. Most guys in here run a 15inch lcd backwards to correct this problem when not using a mirror, so we have a few options to choose from.
Trev
ACE, you've raised another question.....
I don't plan on going through my computer......just directly from a DVD player or my XBOX or PS2......
how would i hook up to a vga input?....i believe i've read about converters but any i've seen have been a rather hefty purchase

Heya low, wow what a big post! lol next time it might be easier to just post up a referal post with the link to that page:) , but yeah the other thread was getting off topic, thanks for bringing it back over here.
Regarding the vga question, the lilliput lcd has 3 inputs, 2x rca and 1x vga, take your pic. With a vga converter somtimes if its not a good one the results can be the same as rca, some even worse. Unfortunatley they cost a fair amount of money and with the amount of inputs you have with the quality of the lcd i wouldnt be too fussed in getting a vga converter. The quality of this lcd is good on rca, its sharp and clear, but just not as sharp as vga.

Not at all on this lcd, but vga is the best source to use on any monitor, its like comparing your tv to a crt comp monitor, the tv has less resolution and looks murky while a crt comp monitor is sharp and clear, this also has to do with resolution aswell and probally isnt the best comparison but you get the idea.

That PSX lcdscreen look exactly like my old playstation screen, I had a big problem with it, it had only RGB-input(playstation AV-plug) and no compositevideo and no S-video input so the only thing I could connect it to was a RGB-dvd-player. RGB is the best typ of input put it´s only work on stuff that outputs RGB, composite video is normally crapp if you compare to RGB or S-video but on lowresolution screens it works good.
If the input to the PSX only is RGB = Problem, there is no cheap way to convert composite to RGB. |

i'm not looking to get that into modification just yet.......
i've seen some psx screens with rca jacks and am probably going to have to go with one of those to start.......
if i use one and get even half decent 40 to 60 inch projections i might try going on from there
with a recent illness in the family and travel expenses it's going to be even longer until i can get started.........

I recently harvested a screen from one of those PSone lcd's.
Slapped the whole thing together last night and documented it.
You can check out my results at

This is about 50" at 8-9 feet from the wall.
Im allready working on a metal and wood housing for the screen.
The picture is way worse than the projected image. |

So if i was to do this could i do it similar to lumenlabs design. What type of light source should i use for this size of lcd and Ace what was the 11$ copy lens you were using it and where can i get it? Thanks |

I wouldnt suggest buying a PSone screen to do the project.
Unless you can pick one of for dirt cheap, or free of course.
Spending anything over 50-60 bux probably wouldnt be too wise since you can get one of those visor screens with better resolution.... and bigger too.
Definately don't get one from the store. For a hundred dollars you could get a much more impressive screen. |

I live in a ****-box little garage apartment, so I don't really have room to throw a very large image.
Biggest I can go is about 70-80"... The pixels are plainly visible at this size up close... but not too bad. I can still watch it comfortably from 7-8 feet away.
You can see how much better the picture would be with a higher resolution lcd
The light source is an unmodified 3M 522 projector.
I have no idea about the lumen output. Brightness isn't an issue though |

hello everyone, ive just recently registered, but ive been lurking around here since before christmas of last year, learning alot and slowly gathering the necessary materials and part to make my first video projector. i decided to post here because i have one of those psx screens myself. its dismantled already, im basically waiting for the chance to get my light source so i can get started on the engine. ive decided to go with a metal halide lamp, but im not sure about how the wattage.. ace buddy, do you have any suggestions? i was thinking along the lines of 150 or 175 watt? i know i will not get very good results with this screen, (not as well as id like to anyway) but this is my first attempt at all of this, so it will be mostly a learning experience for me..
also ace, i am confused as to whether or not you have released your plans for your 7" lillput yet for purchase. if so, i would like to order some from you. im gonna be buying one of those monitors next week, but i wont attempt anything with it until ive completed my psx experiment first and learned a little more about all of this.
oh and lowjacker if you need some help or advice on taking that psx screen apart, ill help you out. maybe we can exchange some ideas on the way and be noob allies :D :) |

They claim to be the cheapest. (They don't have the actual playstation screen)
For dutch people, bol.com sells them for 50,- euro's
(don't know if this is correct) bol.com |
So, could you please confirm that at bol.com is the original Sony version?
Thanks
Btw. quite a rip off again ~30$=49EUR ?
damm european prices.. |

Bol.com said to me that it was the orginal psone screen, but i don't have any prove. 50 euro = 60 dollar.
I am gona buy this screen if a bid on marktplaats does not go on. |

There are a few pictures of the unassembled PSone screen on my site.

Its really simple... Just be careful with the ribbon cable that connects the lcd to the controller board.
Also... for you guys thinking of buying a psone lcd.... IMHO, you shoudlnt.
Unless of course your getting it for dirt cheap.
You will get much better results with one of the 80+ dollar screens on ebay.
Its definately a cool little screen to play around with but if your actually gonna invest money... I wouls say to kick in the extra 20 or 30 bux and get something youll be happier with.
just my 2 cents. |

Hi, thanks for your advise, however, we don't have the ebay bonanza overhere* to get a decent lcd panel for 80bucks here is an utopy unless you are working in some lab/manuf. service facility etc..
Well there is the ebay.de (germany) nowadays which seems to take momentum in the last year or so but still the supply there is a bit limited.
I was thinking about the PSone display as a good starting point and 50EUR seemed pricey but manageble otherwise I'll go straight for some full panel aka 15" Benq etc.. and thus something in the middle is not an option in my h. opinion :apathic:
What is your major complaint on PSone display is the low refresh rate or resolution? |
|
|
| Poseablejesus |
resolution definately.
Very obvious screen door over 50 inches or so.
If your staying at or under that it's watchable for tv and gaming.
The refresh rate is actually pretty good. No real complaint with the colors either.
could be better... but performs quite well for what it is.
I think you will be happy playing around with it for a while, but will want another screen pretty quick. That's all I meant to imply. |

i figure if the sony has enough of a refresh rate to play ps one games it should be able to decently handle xbox games.....
at least that's what i'm hoping.....
i plan on projecting only a 50 or 60 inch image which i believe the psx screens can do decently.....
like with othersif i'm able to compitantly do it with the little cheaper screen i'll try something a little more complex later.......

would a 500 watt (7800 lumen) Halogen tube light be to much for a PSX LCD or 7"?
Also would it be to hot for the LCD?
I asked about the halogen because they're only £2.99($5) for two bulbs. |

I've been following this thread for a while now, and tonight, I took a psx screen apart that I got off ebay for $15. (no power supply came with it, but I was supposed to get one this week, and it's not here yet) A couple of problems I encountered were not taking the speaker grills off first, and cracking the case while trying to pry it open. Once inside it, I folllowed the hints and tips from this thread, and everything came apart without incident. While I've dissambled entire cars down to a shell, and put them back together again, this is all brand new to me. I've read everywhere to be careful of the ribbon cable, so I didn't even want to touch it, but I couldn't figure out how I was going to get this thinng to at least 90 degrees without messing with it. so i pulled on the little tab, and it popped out. That made things alot easier. Sounds silly, but I hope I was supposed to do that. Will post pics as soon as I can find a power supply, and find out if it even works. Even if it doesn't, I have another screen handy that I've seen work, so I'll try that one next.
I consider this my practice for the big day when I try and strip a real monitor, so the education is worth the $ right now. I can remember building a radio from a heathkit about 25 years ago, but that's a long time ago, and this stuff is just a little more involved :) |

^^ You did right.
It's impossible to mount the screen and board at a 90 with the ribbon cable through the slot in the board.
That gray fastener tab is a lifesaver.
Just be mindful not to force it. If the ribbon cable is seated correctly it will snap down very easily.
I'v even forced it out by pulling the screen with the tab down on accident. The tab poppped up and the ribbon came out. I'm lucky it didnt mess it up... but it shows that the ribbon isnt "super" delicate.
I think bending the cable back and forth too much is what poses the most risk.
Good luck with your endeavors. :up: |

| Congrats to your first disassembly, did I get it right that you have another spare unit? Would you be pls. willing to sell me that one in case you end up with two functional units. Thanks :hot: |

Thanks for the verification on removing the ribbon, but I'm not quite sure about something. If you have to put the ribbon back on without going through the hole, wouldn't it be going on in reverse? I was able to re-insert it through the hole, and get a 100 degree tilt to the screen, so the board is not interfering with the screen, and it did not feel like I was really forcing anything. I'm planning on using this in a custom enclosure, so if I could keep it with front of screen facing light source, i won't need any mirrors. After my post last night, I tried it with an adjustable power supply i remembered I had, but got nothing. (it's only 300mA. though, and the sony one is 2.0A) Pictures will be coming soon
Thanks |

Thats what I get for assuming you were going to plop it on top of an OP. :xeye:
I don't even know why I said it was impossible... that was misleading... sorry.
You could definately have the screen at a 90+ degree through the slot, but that leaves too much board on either side of the lcd fpr MY purposes. If I tried to lay it on the OP like that, it would either be sitting at an angle or the card would lay on top of and block part of the lcd
With just a little more length on the ribbon you could lay them both flat, end-to-end. Would be More convenient for me.
And it does make it upside down, but I can just turn the whole thing upside down on the OP. Something you also have to accomodate for on your enclosure.
I just got a sony qa-1500 for pretty cheap on ebay so I'm fiddling with that right now... But im thinking about making an enclosure for the PSone screen too.
I'm looking forward to keeping up with your project as it progresses. You should start a new thread when you get pictures and what-not |

Yeah - i should have mentioned I was building a custom enclosure for this one. I actually got it working tonight! I went to gamestop, and the had a car adapter for $8, so I hooked that up to my emergency car jump starter, and viola, it powered up and I got a nice picture. I plopped it on my overhead, and was got a nice reversed image, just what I wanted. I'm using the guts of a 3m 9200 for the optics ($40 shipped off ebay)and lighting, and will stop by salvation army later in the week to pick up an old tower case to put it all in. My goal with this one is a cieling mounted unit above the pool table projecting a 45" image on to a pull down slide projector screen salvaged from mom's atttic. I'm going for under $100, and so far I'm at $72
i also have a qa 1500, here's a link to my setup: (I added one pic of the psone screen tonight) Who says you can't have a projector in every room :)
http://www.diyaudio.com/forums/show...7374#post327374
It's page 14 of post your results
Since then, I've added a nextvision 5, and connected the ps2 thru an s video cable, and both of those actions led to a crisper, much improved image. I also have an infocus 3600, and an old dukane with 16 colors, and I have to say, the build quality on the sharps are very good. Good luck with yours, and thanks again for your help and encouragement so far |

| Anybody that has taken apart the psone lcd I could really use some help. I dont exactly know where to start i unscrewed the part with the controls on it then i kinda pryed it up but i dont know what to do, should i keep on prying? |
|
|
| Poseablejesus |
Well, My screen was sans Case when I got it, so you might wanna wait until Doc or one of the other fellows gets back with the disassembly still fresh in their heads.
My dislaimer of sorts... :)
That being said... Just take out all the screw and crack that baby open.
Just be careful not to put pressure on the screen and crack it while doing it.
You can't really mess anything up, Your not gonna need the case afterward are you? |
|

I found two more screws under the speaker grilles after I cracked them off with a screwdriver. I don't know how you can get the grilles off without ruining them, so it seems like either you ruin the grilles, or you crack off the plastic prying it open all around the edges. Mine came apart fairly clean, and I actually re-used almost all the parts to protect all the electronics.
Hope this helps :) |

LoL no, do not pry it!! most casings for electronic equipment disassemble without force once all the screws and what not have been removed. for the ps screen heres my advice:
1. the rubber pads that sit beside the screen hide screws beneath them, carefully use the corner of a razor to lift the pads. they are adhered with glue.
2. the speaker covers conceal screws as well. once again, carefully with a razor remove the speaker covers. (works best by sliding the blade in between the edges of the speaker cover and where it meets the case of the unit.) take your time and be careful, they should come off without too much hassle. once again, they are simply glued on.
besides the obvious three screws you can see with to begin with, thats about as much work as it takes to get that thing open. good luck everyone. |

i hear all this about "cracking" and "ruining" and i must say, its a bit funny, i went and bought that screen brand new at a store, (i know waste of money considering how much i paid, but i needed to experiment and it was the only lcd i could get my hands on at the time.)
anyway, brand new in the box, take it home, spend like 30 minutes trying to remove the sony seal carefully from the box (as to make it appear unopened) i take the thing apart all the way down to just the screen and two main boards and use it for and ohp setup.
now i never intended on keeping this screen, i purchased it only for experimentation and educational purposes. my whole point to this post is that i was able to completely take the unit apart down to its bear innards (without cracking and ruining things). i used it for one day on my ohp while i got a better understanding on how light projection works. once i was finished, i reassembled the unit just as it once was, repackaged the whole thing and took it back for a refund. and the next person to go out and buy it will never have any idea the things it was being used for, and it will still look and function like its brand new. :cool: |

I have been building a case for this sony LCD but it seems I have not that much pace left to put the controller board. What is the size of the controller board? Can you tell me this? Wat is the largest distance between controllor board and tft? I have not ordered a lcd yet because i want build my case first.
Thanx |
|
|
| Jroxx |
the controller board is roughly a 6" circle.. i cant imagine how in the world your designing your projector case without having the insides there with you.. seems like it would be rather tough. :confused:
the max angle you can get with the ribbon cable connected to the pcb is about 100 degrees, maybe 110. be aware, the controller board will not lay flat while attached to the lcd.. it must be positioned at an angle to function. |

i don't see how anybody could build the case for their screen without knowing the exact dimensions of the screen......
it's possible i guess but seems like it would make things extra hard for no reason....

Why? Look at my first steps: click. I don't want to rush things and I first want to know if i could get any projection at all. (I only use 70 watt MH). I can, so then the next step is an lcd. If i have to rebuild my case or modulate it, so be it. Do you think that large car factory's build only one design and thats it. Building a prototype will give you more insite. |

90 degrees is no problem? |

well, if it works for you then go for it....it just seemed to me (at first) to be building a puzzle when you know all the pieces aren't there.......
but if you're doing alright, and it looks like you are, then by all means keep going......who knows you might just break into a new field of DIY projection

cool man, i just ordered one of those 7" lilliput monitors myself. if youre considering getting one also, i HIGHLY recommend you do. these things are awesome!! i was blown away by the clarity of the picture as well as the brightness and response time. these are great little monitors everyone!! between the psx screen i had and the lilliput, there simply is NO comparison whatsoever. another thing i noticed is screentext is much more visible with the lilliput (obviously, but the difference is huge) than with the ps screen. i have good vision and the ps screen text was next to impossible to read, even on the lowest resolution. with the lilliput there is no difficulty at all, i can read text with no problems now on my new screen. |
|
|
| Lowjacker |
I would like to get one of those screens but first i wanna try my hand at a PSX screen so I can get an idea of exactly how things work....
when I get more experience and money I'll move up in quality, but for right now I'm going with the cheap stuff......
:xeye: |
|
|
| Poseablejesus |
THat's what I keep saying too.
Unless you are getting the psonescreen for free or dirt cheap, you might as well go ahead and get a lilli.
The price is comporable to a new psone screen.
You'll thank yourself for getting the better screen |

i understand not wanting to blow an excessive amount of money or taking risks with otherwise valuble hardware.. however, i must tell you, you more than likely will not be satisfied with that screen!! take it from my personal experience with the thing. i mean literally, i hooked it up, projected the image onto my wall, and was like, "ok, this is cool, but if i had only bought a better screen..."
now, i too sadly went out and bought one of those ps screens brand new for $150 dollars! but on the other hand i was never intending on keeping it, and i eventually took it back for a full refund, which went towards my new lilliput. i must tell you that if youre willing to buy (and not return for a refund), one of those ps screens, they are really worth no more than about $30 bucks. it is my experienced belief that these screens just arent good enough for what us DIY projector enthusiasts are looking for..
dont waste your money man, just save up for a better screen that you can afford. youll be so much more satisfied with your results. i can already imagine the difference in projected images i will have with my lilliput without even taking it apart. like i said, no comparison.
good luck! |
