Well the time has come to spend some time on Plogging the construction steps, materials and results so with some pix I took a while back and the recent ones taken after the PJ was finished I'll do my best to log how this Projector got finally together.

First of all here is the monitor I used a 15' 4:3 DELL E153FP which I got for $175+$25 shipping new on ebay (not cheap but is one of the main components of the PJ after all)...now can be found for $50~75+$25 shipping!

I do not have all the images taken when I stripped the LCD, but it was really easy, if you can hold a screwdriver and can gently pry open a plastic case then you will strip this monitor in no time!

Note: I originally got a 14" 4:3 KOGI which I still have and use sporadiacally for PC testing. The contrast ratio is not that great, but is overall a decent monitor for the time I got it (Jan 2004). Unfortunately after dealing for a long time with FFC issues I found myself unable to use it. The fcc is so tiny that to fix that you have to be equipped for micro soldering and skilled/experienced to venture into trying to extend the an FCC with 20 contacts packed in less than 1 inch space.

Now the LCD ended ended up to be real nice even though I do not feel like I want to take a chance to screw around with the removal of the Anti Glare layer... I guess I am too chicken to do that even if I could always use a more bright image... Well, probably life really is a compromise... right?

Back around Feb 2004 I believe, I got my triplet lens...

... And the fresnels:

unfortunately I only realized much later (a couple years ) that the fresnels were slightly shorter in width than my panel, therefor I get a tiny bit of the projected image cut off, but is really a minor issue since all it does it's hiding just 1/4 of a program icon placed in the standard position on a 1024x768 windows desktop. The Fresnels have the same height as the LCD screen which made it abit difficult to get a good focusing and keystoning especially due to my ghetto lens framing (one is corrugated cardboard )... but if is working great like this the plans must really be foolproof!! LOL

I like this, especially how you allowed for access to the cpu and drivebays.
