Hello
A new project from France...
- ATX Chassis
- Lilliput 618GL70NP/C
- Fresnel (splitted), condenser lens, reflector and triplet lens (varifocal) from a 3M 9550 OHP
- 250W HQI
- 1 mirror
- Screen : 'black-out cloth' 7*7 ft
The projector
And... the result

An externally hosted image should be here but it was not working when we last tested it.

Plans ?
Nothing new in my projector, I use 1 mirror behind the lamp and the panel.

lenses are from a commercial OHP (3M 9550).
Focals are 12" / 12"
The ATX case is a perfect enclosure for that kind of VP (small LCD panel).
The Panel is the same as ACE_3000 Project.
Very nice pics,what is the distance from the screen,the size of the projected picture,any screen door ?
This is the first good pics i see from that small LILLIPUT and i am very impress.
What is the focals lenght of your frensel and do you use one after the lcd.

Thank you Chasse 🙂
The distance from the screen is 4,5 meters, the image on the screen is 2 meters (7 feets)
The screen door is not visible at this distance.
The focals lenght are 30cm (11.81 inches) front and back focal
The lcd is between the splitted fresnel.
The image is better in reality (my camera sucks !)

Great Job,
I´m also building my second projector compacting it all in a ATX case.
But in horizontal axis.
Have you tried to put both fresnell behind the LCD I think it will improve your Sharpness and color definition.
I´m using a huge 400w MH that cant´fit in the Atx case with my current Fresnel FL.
How do you cut your fresnels ?
Did cutting your fresnel modified their focal lenght in any way ?

now thats DIY in all its splender
Thank you cruser
From you it's really a honor !
Bernado,
Thank you too
With the 2 fresnels behind the LCD, the quality was not better than now (splitted).
Cut a fresnel didn't change the focal lenght.
And to cut I only use a cutting blade

How did you manage to get the picture in the right position,i mean did you flip the lcd right to left and up and down or you used a software to do this.
hi T800 how many fans did you put in there, and also any light leaking through the holes in the back??
CHASSE,
I don't use any software, my VP is connected to my DVD player (no computer). The screen is just flipped.
nmd_sb,
4 fans, 3 to extract the heat (5V from an ATX power supply 12V is too noisy) and a little one for cooling the panel.
To avoid the light behind the chassis i use this :

Projection Lens FL
Hi T800
What is your Projectino Lens FL ? and what is the distance between your Projectino Lens and the Second fresnel ?
Bernardo.
Hi T800
What is your Projectino Lens FL ? and what is the distance between your Projectino Lens and the Second fresnel ?
Bernardo.
My Projectino 😉 lens focal is 28/32cm (as the 2 fresnels) so the distances are :
30cm lamp/fresnel1
30cm fresnel2/triplet
30cm lamp/fresnel1
30cm fresnel2/triplet
Hi T800
About the Lilliput:
How do you control de LCD panel ? (OSD)
Do you extend the remote controll sensor ? how ?
Can it run with the front panel (mains buttons) disconnected from the controller board or you just keep it connected and leave it inside the computer case ?

I ve just extend the infra red sensor (with wires) from the panel board to my Bezel.
So I control it with the Remote control, I don't need the control panel but it is still in the case.

I like that idea using a PC case, could i ask which case factor your using? mini, midi, full tower?
also any chance of seeing a side shot of the PJ with the case lid/side off?

Hi Motoko
You can find more shots on our french DIY VP web site.

My case is a PC chassis ATX form factor : 40*40*20 cm

HELP ME
HELLO T800
What an amazing projector? You obtained really cool results, congrats!!
Well, I'm writing from INDIA and I have done a lot of searching and read different material pertaining to DIY LCD video projectors on various sites. As far as parts are concerned, it is very hard to find good resolution LCDs, lenses, lamps here as they are too costly and are not in much demand.
I've visited your link http://allinbox.free.fr/t800/t800.htm, but as I can not read French; I could not understand much (only saw your pics to get a basic idea). It would help if you could mention those lines in English language also on that page.
Six months back I started a project like yours after obtaining a car LCD monitor/TV (TFT) of 7" size, 600*480 resolution and tried the idea of reflective projection, but in vain. Now your project motivates me to restart the work again with the concept of diassembled OHP and transmissive projection. I had to disassemble my LCD monitor and while removing its case and backlight flex cable was detached from LCD screen and some part of the screen lost its display. Please tell me if it can be repaired or it is better to buy a new monitor or LCD panel like Sharp QA-1650 with VGA. How to increase the lengths of Flex cable?
You used a 7" Lilliput XGA monitor and optical parts from a 3M OHP projector 9550, right??? I would be very grateful if you send me the complete plan/schematic of your projector design with detailed specification of each part and their placement in ATX cabinet. Please send some close up snaps with step descriptions as your project progressed as not only the final look is enough.
Especially, how did you remove backlight from LCD monitor while disassembling it, how far are LCD, lenses, mirror, Fresenels (cut off sizes?) are placed from each other in the case etc. Any other possible lighting solution you know except your 250W HQI white light?
Thanx for reading my queries, PLEASE HELP SOON before I abandon the project and think that I can never do it.
Best regards,
