No... I don't want to ruin my laptop... I want 1.8" ... I can get a converter which will aloww my laptop to display on a TV screen... channel 3... this is what the pocketvision will pickup and project... rather than a VCR or TV channel.

Here's a $59 US panel that's comparable or better than the 32
1.8" active matrix tft from a land Down Under
You can get a vid signal in to your computer on that lcd better than the mini-tv's we've talked about.
You can also find that Unipac here in the States for a few bucks more, located in several of the posts we've put up in here.
But, the best would be the hi-res Unipac with the SVHS/DVD connection. That would give you a crisper picture for graphics.

i posted that link for those unipac's in the other projector forum, and was wondering if you thought of what kind signal/circuit as needed to the drive the 1.8".
if you can see the pdf file on page six, there are these pinouts:
it's probally only something simple, but i'm really not thinking at the moment. if you fed the RGB signal to pins 22-24, that would be the signal (and related GND), but i'm certain there would need to be an apropriate clock pulse needed aswell.
i was going to follow it up, by getting one of them, and building a circuit, but all that has fallen in the dust, as i prepare for my upcomming exams. i hate studying for exams.
i will email that company to see if it needs a driver board and if they can sell one.
edit: it seems that a controller board simular to this one here would be needed

Hi ppl,
This is the route i have wanted to take from the start. I have (destroyed/salveged from) an old Prinz slide projector, and have the main lens assembly (which is basically what i wanted it for)
I am thinking of getting a casio ev-570 2.5" Portable tv for an lcd, it has 61,00 pixels which personally i think would not be adequate, but i have no testing of it so i havent ruled it out 🙂 i will get it from somewhere i can return it to. As for size of lcd, anything up to about 2.5" is fine, as i have replaced/modified a few lenses with other lenses i have purchased.
I am merely worried that the LCD's pixels will be EXTREMELY visible. Slightly visible is fine, that doesnt bother me, but actually seeing more pixels than the actual picture would put me off 🙂
Do any of you think that this LCD would be ok?
cheers,

That panel will not fit in a slide projector. Maybe, you have some other way to project it though.
That pixel count is at the bottom of what I would say is acceptable. Why not purchase one of the other's mentioned in this thread?!
I would say go ahead and do it, but, you haven't purchased it yet. So, I think I should help you forego the dismay and rec' you get a higher pixel count panel ~80k and up.
If it's a free one you have and you already have some way to project it, it's not so bad and your girlfriend will be impressed that you put it together.
You're right in being concerned of that panel's pixellation. It won't impress Roger Ebert. Roger Rabbit might like it though, as cartoons seem to be okay (less definition required) on an lcd of this pixel count.
Assailant,
Don't bother! Get the driver board and save yourself the headache.
You'd have to be able to make a board of your own, with such skill, that I would be suprised if you still had hair afterwards.
For the small panel Unipac's it's probably only 30-50$ and you can keep your curls!
Cheers!

hehe thanks,
the reason i chose this panel is that i can easily obtain (and return if i dont like it) in the UK. Also makes it easier having a controller board etc already there.
Casio do a 3" one with 89,000 pixels but that would be just beyond the boundary of the lenses i have.
cheers,

Yeah, size matters! HARD to do a lot of optics work cheaply with anything above a couple of inches. Gal's appreciate it though, nyuk, nyuk, nyuk.
Re: 371k pixel's, they are probably counting the RGB's separately. It's one of those confusing things you have to confirm when purchasing.
When I spoke with a tech regarding the "line's" view on resolution they said to decrease by 40% or so the actual pixel count to get that "lines of resolution" number (I still don't understand exactly). The number's they show put it in the typical NTSC tv picture range though, not DVD/SVHS quality.
If you can get one of the Delta lense's to project through, it would probably put out a decent picture. Little on the pricey side for us yank's. But, that's how things seem to be over der'.

I'm waiting 4 price details about a pretty high res TFT LCD (a unipac one) from a UK supplier.
http://www.midascomponents.co.uk/Displays/tft_displays.html
It's the UP018D11
I very much hope this one is within my price range (about £150) cos i'm very desperate to get this done b4 a good world cup match 🙂 I's also like to get it done so i can make a nice sony branded enclosure 🙂 and make a microprocessor controller for control of zoom,volume,brightness etc from a remote control
Anyway, wish me luck, price wise! 🙂

i've been kinda looking over this thread, and have a question...
it all seems like a great idea, BUT, all those panels are really really low resolution... mine is 640x480, and its noticably low on a 72" diagonal screen. plus, the screens seem to cost quite a bit more. is this one really worth it?

We haven't got any pics of ppl's results yet, but personally im very hopeful. I'm not too bothered by a small amount of pixelation, just as long as i can see whats going on that fine 4 me 🙂
P.S the one i posted above is 528x220, that isnt that far off a 640x480, especially when its only needed for video input.
cya,

Yes, vga/svga more expensive for this size
The glasses that Gunawan mentions up above are $650 new, for SVGA. That's for two, .7" panels! But, one driver.
Or, you could possibly have the basics sitting in your closet, for free! Little tv and slide projector. You could be watching a giant picture in a few minutes. Sheer thrill alone will keep you looking at a pixellated screen for days, if not weeks. That's what I'm really trying to show here. But, there is further potential!
The Unipac mentioned above is an enjoyable picture. You can get that in the states for $160 (Buy it in the 'States law, cheaper!), SVHS/DVD connector/quality. Then plop in your slide projector. Not much messing around to do. The contrast ratio is pretty good on that one too ~200-240. Possibly, >/ = to some of the better OHP panels.
Ultimately, you could fork out the $650. Then, you could make the coolest little projector of your own, with SVGA input's! Very portable potential there. Plug in your cig lighter or battery pack. Great if you were a mobil DJ! Street performer, what have you.
I is a english teacher now though, so funds are limited. Overseas summer airfare and tic's to the World Cup have wiped me out. Otherwise, I wouldn't have hesitated on those.
Also, the sony glasstron's I purchased through auction came out to be a dodgy risk (no return, no insurance shipping and PO box. Wouldn't even let me look in person!). Those would have been decent too ~$200. If I knew they worked!

Hey again sushimaster.
Have u tried the 528x220 unipac yourself?, do you think it would give a nice picture at about 60-70"? good enough to watch the world cup and actually be able to see the score in the corner clearly? 🙂
Also, the $160 price tag u mentioned, is that including the controller board?
thanks again,

hum, i just don't see it.
think about it...
you have a 5 foot screen....
assume that you are using the whole thing for width... you only have 220 pixels wide right? well, do the math, 220 pixels squeezed into 60 inches. OR, for metric people, thats 132cm.
so...
a pixel would be .27 inches, or a pixel would be about .6cm. thats kinda big...

I agree with you on that, but the dot pitch on these things is smaller than a larger lcd, the pixels are obviously smaller also. Convergence of these pixels would be a lot tighter in this configuration. But i do agree with you that it would be pixellated, and i will try to sit as far as possible from the screen 🙂
p.s great pictures u posted of ur setup btw
cya,

I usually sit about 10 ft away for 6'-8'ft pic
A 5ft screen is pretty good too. I thought about making a rear projection of that but, not sure where to get the correct type of screen/glass. Fine-grit sandpaper some glass?
528 is the width/horizontal. 220 is the vertical.
Maybe, I'll be staring back at you on the screen of your projector when you watch the Cup. He-he! I'll probably be the blue dot, because I'm sad. Or, maybe the green one. But, definitely not the red one! Unless, they allow beer there.

SushiMeisterX,
once upon a time...i had built a rear screen using a kind of milky milky foil,that's a material that architects use for drawing. It's much more uniform than self grinded glass or acryl.
There are also options to get cheap rear projection foils from Gerriets.
www.gi-info.com/projscreen.html
They have all kind of stuff for theaters and arts presentations.
Have a look at the opera foil! It's used by lot of HT-people.
Alles klar?!

The score may be seen. But, I haven't taken a look to see it's actual screen size on the US re-broadcast's. I'll check it out this afternoon when they're on again, on ESPN.
I'm not sure if that will be the same font size as your's though. I'll take a pic and send you and tell you if that one would be viewable. Send around 10pm your time.
Yes, they include the controller board and shipping too! This is one of the panels I purchased a couple of years ago. I installed it for a university bud. We watched a few Baseball games and the score window was on the guessy-side for #'s like 8,0 and 6. We didn't have it hooked through the SVHS output, though. This drives PAL too. As that's a higher-res signal than NTSC, it may be more legible when projected. That was ~ a 6' screen.
Marshall Hi-res 1.8" Unipac $159 US incl driver board & shipping
A way to test now, the score's legibility:
For an alternative, try using a paint program on your comp. Plug in that res as you create a new image. Type a few different font sizes that you think are comparable to your tv score-font size. This may be a good representation of what you'll see, as you can judge the font size on your tube with relation to the font and resolution you've artificially created on the comp.
xblocker,
The foil you mentioned is a thin plastic?
The opera screen mentioned is .5 gain. I will have to read more as I'm unsure how to decide what gain is appropriate. You say this gain is commonly used by HT folks though...does a decrease in gain correlate to a higher contrast picture?
