A Practical Guide to DIY LCD Projectors

Compu486 writes "Inventgeek.com has a new article entitled "A practical guide to DIY Home Projection". The guide covers the basic theory behind projection and provides a step by step guide for a "Practical" DIY LCD Projector. Although this topic has been covered before, the perspective they offer is refreshing."

Not a good field for DIY

[Arthur B.]

I don't really get why one would want DIY here... Having a video-projector, say for home-cinema sake or gaming is mostly about quality of the picture. Apart from the sake of learning I'd rather buy one. Oh, and not a LCD one, at least a DSP. Although laser projection tech has been around for some time now, I'm really surprised that it's not used. Although sounds like a feasible DIY project.

My wife will accept one in the living room.

Otherwise this is just another "Overhead projectors with LCD panels make big ugly projectors that you cannot use anywhere but a darkened room" story.

spend the same on a widescreen CRT but sit closer

a 1024x768 screen is going to look pretty damn pixelated blown up to 100" unless you sit quite a way back!

It's Not Worth It

The author of the article keeps saying it's better to DIY than spend $5K on a commercial model. However, you can get a decent projector for $800(or less if you buy a refurb non-current model). Plus, the picture quality is a lot better(supports 480i, 480p, 720p, and 1080i), and is in an appealing form factor.

The other question is how noisy is the overhead projector? Remembering back to elementary school, those things were pretty loud.

DIY?

How is this a "do it yourself" project? You bought an overhead projector. You bought the LCD display that was made to go on overhead projectors. You bought a screen.

The only DIY here was "Make a box with a window in it" and that's not really a "Do it yourself LCD projector" now is it?
