So sushimaster, this did give a nice picture then?, not too pixelated? Do u know if the company link u posted deliver internationally?
cheers,
cheers,
I think you'll be pleased with it.
Those Sony Glasstron 35's are better if you can win a Ebay auction ~245 $us for the 800x235's. That would be about the cost of the panel you were gonna buy in the UK, previously.
I'm not sure about overseas shippin. They might subtract from their usual US rates though. Check out about shippin to your country. You might not have to pay any tax on that. Also, ask them to ship as a "sample" on the shippin invoice that might help taxes at your end, if there are any.

One more question; how do u control the brightness/contrast on these things, or is it not possible?

i think before there is more research done, i think somone needs to post some results... i am still totally unconvinced that ~220 can be stretched out over 5 feet, with a 1/3" pixel size and NOT look pixelated... instead of thinking of creative testing methods, why not just watch a movie or TV off of it?
plus, $600 for screen, plus $200 for projector, for a LOW LOW LOW resolution solution is insane. we need results before we can entertain this one.

I agree totally, i personally would like to see screenshots first, but it looks like it might be me taking them.
Btw: it is 528 pixels across, not 220. it seems that for efficiency you sacrifice pixel visibility (unless you are rich and can afford an svga/xga 0.9" polysilicon lcd) 🙂
Sushimaster: did u say that you were getting another one of these lcd's? 🙂 as you posted the unipac stuff in the first place its only fair that i let you take some pics of your working setup b4 i buy 🙂 lol 🙂
I think i trust you though, i just wanna watch films, im not looking to do any CAD work on it 🙂

very true. not gonna be doing CAD or design on the thing. but, i have the 640x480 one right now, and i would like to decrease my pixelation by about 2/3. i think mine is marginally acceptable for a middle of the road projector. its not low end, but its definately not high end. but why spend $600+ on something you use only to amuse friends and ****? i use mine every chance i get, but would still use it more if it was higher quality. i think if i only have 220 vertical pixels, i would probably only use it spariingly... big is nice, but my monitor displays VERY nicely. its a lot to give up for a strained neck, and novelty factor. i think the original idea in the DIY projector was to make one just as good as the commercial ones, which can be done without a problem. however, we need to pool USEFUL information, rather than run around like chickens with our heads cut off. there is too much useful information in this damn forum.
sure, its great if someone found a color LCD module that is only $5, but... WILL IT WORK? let's buy one first and figure out if it could work, THEN, we can make it better and cheaper. right now, there is no prototype, we are trying to start from nothing and get to a perfect end product for like $20. um, right...

I see what you mean and i wish that their was a higher resolution panel for a good price (or even for a crazy price, i cant find any small lcds of very high res)
Does anyone know of any TFT's that have an even higher resolution than 528x220 but are about 1.8" - 2.0" in size?
cya,

cya,
Pursuiving all the discussion about this small panel thread, i would say, these small panels can't be a solution. If resolution is below SVGA or even VGA, this isn't satisfying in the long run! If someone wants to proove that an image can be projected with these small panels, ok...,
but would you sit on the couch and enjoy world cup or movie videos WITHOUT PERMANENTLY COUNTING PIXELS ??
There are a lot of low pixel PJs on the market like sony's cp100, fujix 700, citizen 30....Crap! Toys! Before i would spend 200-500$ for low resolution panels, i would look for older single panel (S)VGA Proximas, ASKs, Optomas....They often have inexpensive halogen bulbs, you don't have to fiddle around with lenses, reflectors, filters, i mean, a better choice.
There may be not so much fun than DIYing them, but it's more fun to look at the image. Nevertheless you can DIY screens at your choice. This can also be a sophisticated job, when it comes to gain issues.
I think we have to accept the fact, that actually there aren't small high res full RGB panels on the market, which match real video requirements! Maybe this will change, with mobile TEL, PDA developements. On CEBIT they showed a mobile tel. with an implemented projector, of course poor resolution.
I don't wanna keep anybody from builting projectors, it's a lot of research, learning, fun, failure, but if you summarize at the costs, you will not be not much away from these (older) single panel PJ prices.
Another 2 cents..

Oh, my Buddha! It must be Monday...
If you'll look at the very first post and my "charter" statement, I say:
'Starting a thread for the small panel approach to projecting. We are the few, the lazy.... the marginally contented!'
I swear my heart and the blood it pumps, this to be true!
Please read on!
I was hoping to get a few 'happy-go-lucky' folk to realize that something could be thrown together with minimal fuss. This isn't for everyone. But, sometime's you have everything you need in your's or Grandma's closet. But, this is the end of the quick/novelty approach. Read on, nay-sayer's. The future unfold's! "Dr. Whoooo, HEY, Dr. Who, Dr. Whoooo, HEY, Dr. Who!"
(Sorry, the 'Wings are groovin. Up 3 pts! I smell Stanley Cup).
DIY, doesn't mean "State-of-the-Art". It means Do-It-Yourself. And, any of the means discussed will do exactly that! You have my promise.
Let's continue,
In logical progression towards projection bliss (is it ever attainable!?):
CowanRG & Xblocker,
YOU CAN get two (because they are in VR glasses) .7" SVGA panels for around $650. They can be bought new and are readily available. Small size is expensive. But, for a third the cost of the new 3 panel cheapo (Epson?) projector mentioned on the main thread, YOU CAN build your own SVGA MINI-PROJECTOR.
That get's my noodle shakin'! I wanna be the first kid on my block!
You can also get the hi-res Unipac's and they ARE enjoyable too! (No pixel counting neccessary, albeit fuzzier than VGA) Or, gut some Glasstron or Eye-trek, VR glasses.
There are SVGA of these, for ~$700 and 3/4 VGA version glasses for ~$250, at Ebay.
I'm not sure where the $600 screen come's from. I just removed my velvet SHAFT painting and watched it off the wall. Also, one can purchase a busted projector with everything you need for ~$20 at the pawn shop.
C'mon guys, this stuff's been stated on here several times.
For 30day thread review. Three flavors of 'mini':
1) You can go FREE, CHEAP or EXPENSIVE for your small projector.
2) Free=free, cheap=~$200 and Expensive ~$700
3) Free=1/4 VGA or worse, Cheap= 1/2 VGA and better,
Expensive=SVGA, Nirvana!
* All assume you have a projector already. ~$20 used-$50 DIY.
** Screens are up to you. They're nice and look like you can make your own for less than ~$50
I don't think much more can, or should, be said. The various resolution's are stated here, as well as, the capital layout's req'd.
All fit the DIY description and the BEST fall's ~3 times cheaper than a manufactured model!!!
Not, to mention the portability potential!
Come on guy's, let's come in for a group hug!
And read this stuff. There's truth in it.

yeah, i hear ya.
but for $50 you can get a projection panel on ebay, 640x480, and then for $100-$200 on ebay, a NICE projector...
so, for $300 lets say (just to emphasize my point more), you can have something 10x better than your $600 lcd, etc, combo...
and, its EASIER! less time, less fuss.

thelaw,
Have to wait till tmrw for the pic's. After mowing 1 acre of grass this afternoon the sandman got me.
That panel has 5 or 6 separate visual controls. They are surface-mount potentiometer's. I set the contrast high and the brightness/picture nearly as high. The more light you can pump through at that level the better it looks. Then, you'll probably need some extra cooling. Since, at that point the panel is black and absorbing a lot of heat to produce those on-screen darks.
That's when I was going for a wide-screen 10 footer.
I understand if you don't purchase and prefer to wait. I would be skeptical as well. However, first free $160 I see will be picking one up. And if ~$650 presents itself, oh-boy!

cowanRG,
Where do you get the $600 figure?
The 'Cheapo' version can only run you $300 max. With a screen and projector.
For $750 I can have SVGA, though. I don't need a nice projector. And the fuss of optics is negligible, if non-existent. It can be very small too. And higher res than your VGA by 30%. Nanny-nanny, boo-boo
SVGA's much better for projecting comp games or anything for that matter.
It's your choice, small or large. Each has advantages and disadvantages. That's all really.

sigh, ok... not $600, but $300 lets say, $200 or $150 for each, roughly (roughly ok?)
now, we are comparing apples to apples, price-wise anyway...
so, here are comparisons:
Small Panel: LOW resolution, (1/3 resolution of a 640x480 display. multiply out pixels ~500x200 = 100K pixels... 640x480 = 300K pixels.) Hard to use, most controller boards aren't easy to move, and most people dont want to mess with very sensitive electronics, (not to mention the blatently obvious, yet overseen fact, that exposed electronics give off and are exposed to interference). however, units are smaller, easier to move around, and more space-efficient.
Large Panel: EASY! buy 2 things, slap em together, done! no screwdriver needed... resolution is 3x that of the small panel, and if you shop around right, it can be even higher. again, if you shop around, you can get MULTIPLE inputs. once again, no messing around with bare electronics. however, larger, and harder to move around, etc...
so, all in all, you gain a little space by having a small projector, but sacrifice in quality greatly... who wants to watch a 50" screen that only has 200 pixels??? 1/4" isnt that small, you can easily see it from a good 10' away... i understand that maybe you are going this route because its easier, and maybe cheaper, and you arent doing it for quality... but your reasons are defeated also... your LCD panels are more expensive and greatly inferior in quality (in terms of resolution/inputs). PLUS, you gotta mess with electronic components. you arent saving effort, nor are you saving money.

cowan dude! For the 4th time, it's 528 pixel's!
Look, they aren't hard to move. From out of the box, in less than a minute, I could have that Unipac (et al) panel sitting in a projector, projecting.
No shorts! 1/2 foot of duct tape, will take care of that.
They aren't SO sensitive! Only concern is the backlight and who care's about that, it's disconnected! I never had a problem!
If you are really-really searching for a downside to these than I would say, they aren't all-over the market and the price is 30% higher than a comparable OHP panel resolution.
BUT, what you're gaining is ~10 cubic feet of space LESS. And 50% more cash get's you SVGA! Not, inferior vga, that you have! he-he-he. C'mon, smile!
Miniature is almost always more expensive, in the beginning. No matter what type of technology.
To the point, space and money are the only difference's to be made between the two. Nothing else!
And the money part is closing-in!
This is the future!
Finis!

show me one of these small panels that is REASONABLY priced, that has SGVA.
it doesnt even seem like you are listening, just ignoring me so you can make more posts...

sorry, didnt see your subject...
i realize its 500+ pixels, and some get up to 1400+ pixels.
but they are all 220 vertical! thats NOTHING.

If you require more info, please read the prior posts, carefully. It's all there and coherently stated.
I've spent a lot of time concerned with how to explain something to other's, from Padawan to Master Jedi. He-he!
This topic has come up at least 3 times. I'm just tired of repeating it.
Research your idea and state your case exactly. Then we can make some head-way. You have to site my/anyone's statement against what it is your trying to prove. This highlight's your point and then we all gain from it's outcome, good or bad. Without that, your statement won't have the strength it could otherwise.
With regards to OUR discussion, a theme of 'money spent' is apparent. Money spent does not always match widely with the universally-varied spendee's intentions/wishes. Some things are inherently subjective and open to your personal view only.
Silly example:
Beautiful cow making milk and ugly cow making milk, both make milk equally but, beautiful cow is more expensive. Which is more important to own? Where do you draw the line? Is your line the same as another? Does your line have to be the same as another!?
Sometimes, we're the seed and sometimes we're the sower. But, both grow nonetheless. Don't see it as an attack but as a chance to grow. I'm serious.
It's just a video projector thread of the small type. I've not mislead anyone. This isn't a forged Golden Wonka Ticket.
To make my case crystal clear. Looking at your last post can I not say also that an XGA panel makes your's look like "nothing?". Can I not also say that all should have XGA. To not have XGA is to not have a soul! Silly, isn't it?
Peace, love and vegetable rights

OK Guys,
OK guys, enough... I have a projector ( actually 2)... I don't have $100 ... Hardly $50. ( I do have some nice format camera lenses.... haven't even thought about them yet.
I just want to hear others experience with what is cheap and works... and how well does it work.
Cowanrg... how many projector(s) have you made ?
What was the costs of each?
What equipement did you use ?
This is content needed and welcome in this thread.... Please don't make it a flame board.
Sushi has been sharing his experiences with small panels and This is what I need to hear... If I wanted to consider larger panels there is the other thread.
God Bless ,
Jim
