I don't have any hard numbers (yet), but the vignetting is actually better than it looks here. My cheap but adequate screen has a couple ripples in the bottom corners that create that bluish shadow effect.

Few more screenies for good measure.

Let's see a close up of the bottom half of that sexy projector please

WOW!

What a nice look, now all the wife need to to is stick a big potted plant on top of it

I guess you have a long room with the 22" triplet and the 10.6 you will have a long throw.

I like the swing out triplet too.

It does look like some of the screens are over saturated, might it just be the camera?

Nice light pattern too.

Was that the eBay high heat condenser lens? I bid on one but lost. (WHO was it!)

I'm literally salivating here sensi. I'll second JJ's inquiry, can you please show us a closer look of the bottom half of the bird's eye? And what's the diagonal of the projection and your throw distance?

So it was that obvious that I was avoiding a close-up of my wiring snake pit ?

I was leaving most of the wires loose until I was satisfied with the tweaking. As soon as I can wrangle them into some semblance of order, I'll take a good pic of the her nether regions.

My wife knows better than to touch my mistress. She'd rather not live with the monster I become when/if something goes wrong.



Good eye. I probably do have the controller's saturation up too high. It gives most scenes a nice pop, but sometimes its a little blown out.



Yes. Seems to be handling the 575w beautifully, even in a vertical setup with all that heat rising. I told you guys you should have grabbed one when they were Buy It Now for $9.99.

Aw, hell, who am I kidding. My wiring always ends up looking this bad, no matter what I do. And I'm not about to monkey with it at this point. Part of the reason it looks so chaotic is that I kept the lengths and terminals intact from the Dukane 670, so as to use their handy dandy terminal block (crimped U-shaped terminals that essentially hold each other in place make it easy to connect and disconnect). Then there's the additional wiring to the thermostat (also from the Dukane) that keeps the fans running after shutdown and the 12v converter that runs the 80mm (ballast-cooling) fan and the two 120mm optics cooling fans (the remaining 92mm fan that cools the light section is a heavy duty AC fan from the Dukane). Lastly, there's an onboard outlet on back (bottom left corner in the picture), into which I plug the 1500ma 12v adapter driving the LCD controller, which, by the way, is simply mounted on back just above the LCD.

Each cooling section has its own intake and exhaust. The ballast gets fed fresh air from a slot just below its heatsink fins (and never even gets warm). The light engine cooling is pretty self-explanatory, and the fresnels/lcd have a grated slot just behind them, where cool air gets pulled in by the twin 120s. When the doors are shut, each section is essentially isolated and fairly efficient.

Yes, it's a bit loud. But we sit about ten feet in front of the projector, with our heads and ears behind a loveseat, and in all sincerity once a movie starts we never even notice the noise. And after my first ballast melt-down, I'll live with a little wind.

Last thing that needs to be done is to make some baffles for the side slots. I have quite a bit of light leakage that doesn't really effect anything (again, the projector is 20 feet from the screen, at the back of the room, and the light just hits the back wall) but it still needs to be fixed for aesthetics sake.

The light engine section is a bit of a fudge, as I had to adapt it after deciding to add the precondenser. Essentially the lightbox sits on a metal platform (yep, you guessed it, it's the bottom of an optical drive), which in turn sits on some all-thread for height adjustment.

Here's how the back looked as I was building it. The LCD controller sits between that intake slot and the fan cutouts. The knob above those adjusts the angle of the mirror, using the simple mechanism pictured below.

Aw c'mon, it's not THAT bad!!! You showed yours so I'll show mine . . . eventually.



I was afraid - based on those above excerpts - I'd have to execute some moderation here!!!

BEAUTIFUL JOB sensi!!!!!

Stuff like this keeps me plugging away . . . little by little by little.

And last, a detail of the computer PSU derived lightbox. I had a couple scares with some arcing, when the terminals accidentally slipped and touched the wires holding the bulb mounts, so I removed the bottom ones and now all is well.

Man, that looks good! Elegant PJ box and very nice results. Any chance you can get some lux readings?

Thanks NN. I'm hoping to get a luxmeter for xmas. Gotta save my pennies right now for the kids and others, but I've put the word out that ebay gift certificates would be appreciated more than a charlie brown sweather

do you like this holder

Sure. It's nice. Others may be interested as well. How much?

$10 each, shipping is $10,

Great job man. Those screenies look really nice to me. As for your build, it looks pretty dang clean too. Enjoy!

Thanks, man. Appreciate the kind words.

ver good!BEAUTIFUL JOB

I'd love to comment but unfortunalty I cannot view the pics.

See here. Apparently the forum is still a little buggy after the recent server change.

i nominate this one for the hall of fame ..... wait , can i do that ???

very very clean build
and awesome screen shots


very nice

thanks man. warms my heart to even get nonimated

I agree.sensibull's projector is outstanding!

Nice Job Clean Thanks for the pics

chamal

Fantastic job Sensibull...I'd shell out a fine penny for a projector that looked that nice.

Fantastic looking projector and brilliant results, love the workmanship and the accuracy speaks for itself in the images.

Wow, I'm gone for a few months and the DIY projectors start looking like the put out better pictures than commercial projectors. The vigenting is looks nonexistent in the pictures. What have I missed while I was gone?

BEAUTIFULY done job, she so pretty .
-does your wife like the PJ design, does it fit "her room"

I hope I do this PJ justice, since I now have the LCD from it.
