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."

Go with LumenLab's plan, if I was to do this at all.

And they have real pictures too, instead of faked images on thier site.

Hmm?

Well, you will probably want to invest in a good DVD player. The decoding between players can have a big difference on image quality. I am not a videophile, but in my experience it's not so much the quality during slow, colorful scenes, but during very rapid sequences where you might see issues with playback. The Home Theater Forum is always a great start (they have a very nice moderated DIY section), and I am looking into possibly getting an Oppo Digital DVD which has been extremely well rated. As a plus, places like HK Flix sell it with updated firmware (so you can switch regions easily on the fly), although I've seen it for $50 less on Froogle.

As far as receivers, I can give you my analysis and feedback as a regular consumer (I wouldn't even call myself a "prosumer") of home theatre electronics. You definitely would do well in investing in a good receiver with as many inputs as possible, and don't get them from Circuit City / Best Buy / Fry's as they are usually $100 more than what you can find online. In reality, you will probably not need more than 3 or 4 component inputs (DVD + HDTV + Console + Other). Depending on the # of inputs on your TV/projector, this should put you in the $300-$500 range for receivers. Look for wattage ratings and buy from a well-known company (say, Harman-Kardon, Denon, Onkyo, Sony, Yamaha).

Once everything is set up, get a calibration DVD like Digital Video Essentials or Avia to tweak your settings. It can make a noticeable difference.

You don't need Monster Cables. If you have a friend at a store who can get you the discount (retailer markup is at least 100%), then they're fine. But you don't need to spend $300 on cables. Spend that money on better equipment.

Just do your research. It's possible that over the next few months older models will be discontinued and be heavily discounted. That can always save you some cash.

Proxima 944+? Unobtanium.

According to this link the Proxima Ovation 944+ is 8 grand new. Not that anyone would pay that, right? Well...

None are listed on eBay.

Finished auctions on eBay list at about 300. That's fine, but try to find one!

Kind of eliminates the ability to do this project, doesn't it?

I don't understand why all of these DIY projects have to use some amount of unobtainium. Why not price out some NEW parts, ones that are currently on the market? Leave it as an exercise for the reader to find used or discounted products.

Only then can you make a fair assessment of whether or not one of these projects is "do-able."

I would love to see some names / brands of recommended overhead projection panels - but unfortunately, THAT is left up to the reader. I thought making these recommendations was a key part of a DIY article. After all, look at Woodworking magazine or any other DIY magazine - they all list the parts, the specs of the parts, and typically, a price or two with each.
