Hi Bull,
I took a screen shot of mine, its still too blurry for my liking ( i like perfect ) but still its only an ohp. i need to build one
with a better set of lenses.
The screen is 60" including the black borders, well pleased with it at this stage - well watchable.

And another one of a really dark night club scene, name that club anyone ?
I particularly like the way his shirt still looks a good brown colour.
But you can see the slight softness on the left side of his arm ...

Hey guys, nice results!!
Ryan: It seems very bright!! wich light setup did you use? two dichroic or a MH?
BrianuK: Your seems very good reso! Wich panel are you using? Why it's a little bit blurry? are you using a triplet on your ohp?

yours looks very nice brianuk, god damn that panoview 540 breaking on me, the stupid 530s look awful on tv and things that arnt like cartoons
Sorry disa, me and bull kinda hijacked the discussion abit. Mines a 10" panel.
I doubt its a triplet, it has two lenses at right angles with a mirror.
I think a triplet would only have one lense then a mirror maybe ?
I'll get round to doing a coffee table design if i have time.
I dont see the blur on the panel so its got to be optics.
Also i dont what bulb it is, it just tightens in with two screws ? a cheap halo i suppose?
Bloody noisey fan and its useless, will be getting transplanted soon! by some 80mm effective fans

hay disa, i stuck with the two dichroic and you can see that it is nice and bright, i am using a bit of that heat proof glass from a 150W halo floodlight, i'm going to install unreal and see how it plays, brianuk has the panel i had and broke a CTX PanoView 540 10.4" i really want to repair it and i am trying but its really hard to get my hands on the replacment transistor i need, maybe someone else has another fualty 540 then can sell me, or just the part i need.
Cheers,
Ryan Edge

hay guys good news, i oreder another panoview 540, it should come tmw and i will strip it and try it out.
Cant Wait,

Good luck Ryan... 😉 I did some research about that monitor and I thought it is very very decent one for a diy project.
It is cheap, it is vga and it is stripping is possible 😎

yup its a nice monitor, but beware do not get a 530 there so horrible they look like they only display 256 colours, i have 2 of them.

Curiosities
Thanks everyone, I´ve found this thread very useful for small setups. Before I start building mine with a PSOne Mad Cow 4" I have some questions:
- Does the lightbox u use have a hole or fan? Or is it just in the outer box? How does the heat get out?
- If u use a dichroic fine with a 5" panel, should u need four dichroics to get the same brightness with a 10" panel? ( 4 5"panels fit in 1 10" panel.
- Do u paint the lightbox ( not bright ) black in the inside?
Please add some more pictures of the small panels projections.
PS: From arm to arm u have 1Mohm, with 12V it does not harm ( never try either) , however if u touch with one (big) hand the 2 electrodes of a car battery, your resistace is lower and do not try it. Always put one hand on your back when dealing with electricity, the current shoud not come across the heart.
I hope to have my first setup in a week or 2 a will post the results.
😉 Cheers
Luciano.

Re: Curiosities
nope mine it all just a lightbox with outer lens, i have a fan below the bulbs blowing air up to disperse it, the hot air is taken away by the fan in the psu, i imagen you will only need 1 blub for you setup but you can use 2 if u want a briter image, and currently my light box is un-painted, if i where to paint it it would be black as white may cause ghosting.
i got my new lcd and its great, i also went to ikea today and got one of the white show curitans, i am going it try it out then post some pics for you, i got it for the nice price of £2.50.
Cheers,
Ryan edge

disa81 said:thanks Mathias! I just plugged my light in a 24v power supply...Now it's damn bright!!!!
I can see it clearly now..
Anyway I do need some setup on my projector (fresnel etc) so I will post quality pics when I'll finish working on it!
I'm going to post here the pictures of the image projected by the Mega Pro Game Projector... WONDERFUL..Take a look..😱
so you have a mega pro game projector i was thinking about buying one should i is it worth it and is the image in good quality and the brightness or does it suck thanks
Re: Curiosities
If you touch a car battery it doesn't harms you at all... it's DC, and it's not harmful... (Only if you touch both electrodes with your tongue, in that case it's going to hurt) You can be sure of this because of small 9V batteries, and cellular chargers and almost anything that uses DC current... A PS transformer, or even the LCD transformer gets some 50 watts (and it doesn't hurts if you accidentally touch both polarities)...
The Amperage is not the harmful thing for humans, the voltage it's the dangerous part... Electric Arc Solders works with a lot of amperage, and low voltage, to make it safe to use...
Anyways, I'm going to start a project with a PSOne Mad Cow 4" too, so this posts are more than useful... I will post my results as soon as I finish it...
Just, I have a question... I'm going to use normal lenses, because I have some spares... Is something I should take care of ? 'cause almost al the post always refers to fresnels...
See you soon

I would have to disagree with the above post. It is the current that hurts you, not the voltage. I don't care how low the voltage is, if it has enough amps, you're toast. Plenty of people have been seriously injured and/or killed from a 12V car battery. Granted, the situation for that has to be right, and in general it's pretty safe, but if can and has happened. If you know what a Tesla Coil or Van De Graf generator is, they operate on the principal that high voltage is OK with low current. They create huge voltages, into the thousands or tens of thousands of volts, but at extremely low current. The reason the small power supplies/batteries mentioned above don't hurt you is because they are not capable of suppling large amounts of current, the voltage is not the issue there.
Just to finish the subject...
Just google for that... That's false... Name only ONE killed directly from a car battery (and by the current, cause if you drink the acid inside, it's almost likely something awful will happen to you 😉 ) If I had one in here, I could touch it and register that with my webcam for you... Just ask a mechanic, he has to unplug batteries almost all the time... I does sparks, I scares you a lot if you make a short circuit with cables, but it doesn't happens anything if you touch both electrodes...
Second one: Maybe I said it the wrong way, yes, the amperage hurts you a lot... but what I meant, is that for example, paralizers (are battery operated) they can even make you have a heart attack, and they don't have amperage... In the other hand point soldiers, have like 300 amperes, and 3 or 4 volts in max power, and you have to use gloves when soldering, but becuse of the heat, not the electricity...
Anyways, electricity is harmful, and yes, like you said, amperage hurts, but also it's becuse of the voltage ('cause it's the force making amperes move) but enough discussion... the only case of injury I found on the net:

And you have to be stupid to use your mouth to peel the cable while it's plugged...
This thread it's not about this, so maybe we get banned from here... so let's talk about what it is the matter in here...
I asked something about using normal lenses ?? anyone has clues about problems I could have? I'm afraid of burning the LCD like when I burn papers with a glass... can anyone tell me about that ?
cohort36, I invite you to make a new thread or keep talking somewhere else (not to bother people in here)...

just to keep that I'm not lying about touching both electrodes of a car battery...

There is a BIG however (like in the car talk discussion). IF you reduce the resistance of your body (sweaty, you're wet, etc) it is possible to electrocute yourself with a car battery. It takes milli-amps to kill you. 650 cold cranking amps is more than enough. It'll weld a wrench to the terminals (seen it done). Again, it's hard to overcome the resistance of your body, BUT, it can be done and once you create a path across your heart..... you'll be pushing up daisies by morning.
You can test this with a 9V battery. It's the "wrong" way to see if a 9V battery still has juice. Press the battery to your tongue and you will feel a little tingle. That's your skin (wet with saliva of course) conducting electricity.

where the heck are you guys finding the 4" LCDs? id love one of these! Think about it, you could use a projection lens from a RPTV, meaning a LOW light, low heat lightsource
