Here are a few pics of my 3rd PJ. I reall am not going to be able to take any more pics unless I make a specific trip for it. I found the BenQ 567s V2 LCD to be much better than the CMV/Liquidvideo. The pixels are smoother (smaller with smaller gaps between), smooth black edge to edge when screen is blacked out, and more accurate colors. With finally having full size fresnels I finally get the nice professional looking crips edges and coners. Would be perfect if not for the keystone corection slightly blurring the bottom corners and bowing the bottom edge (not noticeable to the layman).

-BenQ 567s V2
-USHIO conversion
-Big Heavy Cheap Ballast (that sits outsite the box where a ballast should)
-Norpro
-Simplified Focusing Mechanism (using strict cutout sizing lined with fabric for a tight grip on the lens no matter what the position - tapered edge of lens has one layer of electric tape)
-Simplied and less effective light box due to huge Norpro


BLUE WHITE TEXTURED WALLS!

Geez, man! You're making the rest of us look bad...

[jo@joewerb.com]

Thanks guys

It didn't come free. Because I just had to have a streamlined box I paid the ultimate price. I hacked my thumb in a table saw lost a bit forever!

Saws are not forgiving when it comes to flesh! Believe it or not this was the lightest quickest of nicks. The problem is that that spining saw blade doesn't nick... it explodes it! I lost a bunch of tissue/meat and bone was made into sawdust! I will throw in a early pic too with a pin in it to give a better idea how it looked a month after.

aw man, i'm eating sloppy Joe's right now - no kidding too!!

sorry to hear of the loss, but ya know, it seems to 'everyone else' that it was worth it. Nice PJ for sure, and I love the adjutable track!!!

[japlasma]

Joe, you did it again! this time you took it a notch higher - excellent job! and welcome back to the forum, even though you came back to challenge the rest of us by your latest PJ,
Sorry about your thumb, I hope you recover soon - and thanks for the pictures of your thumb - they're the first injury pictures I have seen here - I think they are a welcome sight at the forum because they will be a reminder to everyone using any kind of tools to be extra careful.
What's your next move? I know at one point you hinted doing the SGI 1600SW pj, are you still on it?

[brainchild]

Joe, I'm speechless...

[Maz_Atenza]

thats the best looking PJ ever congrats joe

[kingjamez]

Joe,
What ballast are you using with the Ushio conversion lamp (UHI-s400DD?) VERY nice looking setup.

First of all Joe Sorry about the finger. That is an awesome projector you built. That's an inspiration to me and I'm sure many others. Keep up the great work and happy and safer future builds. Nice Job

[rene156]

Oh' That's some Forensic S@#* here at Lumenlab.

[araczynski]

VERY nice results, I love the sliding track idea, as well as the design of the box itself, will definately have to borrow those designs

curious about how high the center of the triplet is off of the floor? the keystoning doesn't appear to be all that much of an issue, at least in the pics, perhaps more noticeable in person? maybe you have a windows desktop (with text) screenshot that would show the problem off more clearly?

sorry to hear about the finger, hopefully you think it was worth it in the end

[sctele]

incredible....

i just wanted to know joe: do you have any plans for placing the pj design online?

because quite frankly, your pj is simply the best i've seen so far!

p.s. sorry about the finger!

[jo@joewerb.com]

Thanks everyone for all the compliments!

I'll try to answer the questions asked..

araczynski-
I agree that the keystone is not much of an issue in the pic because that is about as far as it should be pushed. That PJ was sold to a friend and I wouldn't feel good about any flaws beyond that. If I remember to measure the triplet height the next time I am at the bakery I will, but telling you that the top of the PJ is about aligned with the top of the image should answer your question. Feel free to use any ideas you see in my PJ's. You aren't going to see me trying to copyright some design aspect of DIY PJ's (for you DIY PJ old schooler's ).

kingjamez-
I am using the recommended ballast from atlanta lightbulbs for the USHIO UHI-S400DD. The big heavy block of metal. See http://www.atlantali...g0827/41256.htm

sctele-
I don't have any plans of putting together design plans for sale or anything. It would be time consuming. Anyone can do this design. I would suggest keeping the design as basic as possible. Using a mirror to fold the light path is ridiculous to me. You still end up with about the same size box, but with slightly different dimension and I would rather have something streamlined and ceiling mounted anyway. Adding a mirror adds one more thing to tweak and adjust and one more way your image can be distorted. If you want to shape a box like mine you are going to have to become a bit of a DIY PJ student and learn the internal tweaking before building a shaped box. I set all my stuff up in a rectangle experimental box, tweak everything, then take measurements, and shape a box around it using 1/4” MDF. Make sure to allow enough room in front of your fresnels to allow for circuit board mounting without intruding on the light path. Basically, make a sketch with mm fine measurements of the placement of all your internals and the lightpath then shape the shell however you can around that. I could have taken it further by tapering the sides in as well, but that would have meant more complicated cuts than I wanted to deal with for the result I was looking for. Tapering your box (especially the front bottom) adds to ceiling mounting and keystone correction by allowing you to have your box a little lower because the bottom front won't intrude on your image (also allows for close mounting to ceiling becasue the rear top won't allows more room when tapered)

japlasma-
I am planning on doing the SGI for my personal use in the future with possibly I 1000w light or a high wattage xenon with 5.5-6K color if I can put together something financially feasible. I figure if I am taking that further step to true HD panel then I might as well kick the lighting up a notch to really give the full effect. Anyone know what a high quality, high power, true HD PJ goes for? Talk about DIY bang for your buck! Anyone share the opinion that a streamlined box such as the bakery PJ would look better hanging from a ceiling than a Cruser style SGI box? This is absolutely no bad talk about Cruser, just looking for opinions. It sounds like the SGI panel is about the same height as the BenQ and just a little wider. I think that would be perfect for the bakery style.
