Cool IBM 15" LCD , 3M9850

Just got an digital camera, So it is my results.

I have to lenghten 9 wires from the IBM LCD monitor,
then place it on a glass which big enough to hold the LCD plane.
I lucky to got an old 3M9850. which is very good condition, I just
use the lower light switch all the time. Very Very happy.

Here's my diary of this project:

http://www.imagestation.com/album/pi...?id=4291451499

I've given up on this project as I'm going travelling around the world for a year. I have sold off most of my components aswell. If I do enter this project again then I'll most likely go the LCD monitor route. My conclusions and main learnings for this project, at least my own attempts at it, are:

1. Metal halide is great. So many people out there are convinced that this is not good solution, but I strongly disagree. Having used this forum extensively, and through my own trial and error I have found that with some tweaking a 400W (5000k) MH setup works great. The arc is about an inch long, and I projected bags of light with this. It should however be noted that I was using an 8" diameter PCX (an absolute beauty of a lens it is, and I still have it). This lens obviously allows the transmission of large amounts of light. The only problem I didn't have time to tackle was heat. I believe this is a trivial problem to solve.

2.OHP LCD projection panels - They come in only two flavours : Cheap, low performers and expensive, average performers (at least in the UK anyway). I reckon they will become useless when lcd monitor prices eventually drop - the sole advantage of them is of course the inherent transmissive properties, but I don't think that alone will be enough in the future, considering the progress people are making here with the lcd monitor methods.

3.Whatever information you are looking for, it is out there already. Whether it be in this forum or not, it is out in the ether somewhere. I spent best part of four months attempting to find pinout diagrams for the OHP LCD panel I had - 3M 5300 (or somesuch). Not even 3M could help me further than sending me a copy of the user manual. I eventually found the pinout on a schematic for an ovation panel which seemed eerily similar to the 3M panel. Imagine my joy when the panel came to life first time, with the introduction of my newly built cable. THAT is why I enjoy projects like this.

Good luck to all of you continuing this project and those lurkers who are still absorbing

James

The specs and results of my DIY lcd panel/ OHP project are here: http://geocities.com/afegerglimmung/ I have found this forum to be indispensible in researching components needed for a good DIY big screen project. Thanks all!

Default Got a decent picture

Well here is a picture of my current setup, before my MH conversion that is coming up this weekend, hopefully.

Click the image to open in full size.

Now as with most digital camera pictures, it actually looks a lot better than the picture shows. This picture is showing Serious Sam on the xbox, so it is running at 640x480. The projected image is around 75" from corner to corner

I am using.
Old Apollo OHP that has been retrofit (before I got it) with 1000w Halogen BRH kit.
MegaShow LCD Projection Panel, 100:1 CR, 30ms RT, Up to 800x600 16mil colors.
Cheap 25 dollar VGA Box from ebay to hook up my consoles.
Da-Lite 70" Matte Screen.

Finally able to get some somewhat descent photos of my projector working. Still don't look as good as in real life of course. The screen is very wavy because I had the fan on and it made a lot of waves in it. I'm using a QA-1800 with a old projector retrofitted with a $1 500 watt bulb.

The image is currently 8' wide with no pixelation.

I just bought a CRT Projector and it will be here on Friday. Once I have it all set up I will post some more pictures comparing both the picture qualities.
