You will need a 330mmFL fresnel if you are going to use the standard triplet.

eaven with the 15.4" lcd?

done - great advice edit 5/20/08

The front fresnel and triplet must be "matched" for acceptable results.

Yup, you need "a" 330 fresnel, but since you're using a 15.4" LCD I don't think you can get it from LL. I think you'll have to get it from 3dlens.com or someplace else.

Or break down and get the pro triplet. One thing to keep in mind. Since the box will need to be longer to use the pro triplet it wont be easy to "convert" a box built for a standard triplet to be able to use a pro triplet. ... All I'm saying here is: if you build a standard box now and you want to go pro later you're pretty much stuck with building a new box.

edit 5/20/08 - have a 18" buhl, you'll see later in the plog. Wish I listened on this one. hind sight 20/20 and all that. used the 320mm triplett and 330mm/220mm fresnels. To use the buhl I need to extend the pj and get a new fron fresnel.




ah, I have been reading* more today and I saw a couple posts on that, since* its ordered and *payed for thats what I'm stuck with. The 650 was put in for 2 reasons 1) I saw many posts that using a 15.4" wuxga lcd sourced* from here ( mind you I'm arguing, mearly explaining how I came to such a conclusion)


update - having re-read the sticky I see I read it wrong. DOH!!!
15.4" wuxga sticky

however whats done is done, I have room to upgrade the triplet in the future I guess. Thanks for the wake up on that guys - not sure wtf I was thinking. so heres the question now - do I call and drop the pro fresnels and etc or just sorce a new trip - and with the 650 + pro trip or an equive ( such as an 18" bes etc) have over the 395 fl fresnels and the s15?

I'm looking at 1.39+- : 1 for the corners ( really* ruff math based on 220fl collector fresnel and a 15.4" lcd ) I just don't want dark corners. I can see now that the 320 fl of the s15 and the 650 of the field fresnel are , um, uneven to say the least.

ok off to search of an 18" then though 18" = 450mm..... < 650... ? arg need to lurke more

edit for spell check

pics of the screen -

Ahhh... looks like a Dell D800 (or something like that). Mine started as a Dell Inspiron 8500

Auction stated 8500 etc etc - we shal see when I strip it ( after the pixelworks, errmm.... works)

I was talking with the wife about my design - which was awesome - ended up needing to be folded however I was going to modify a soccer ball toy box ( internal frame with toy box as a stealthy shell) - apparently she would rather have a haas I'm not arguing. ( still going to do the toy box, just on next build

I just ordered the fresnels form 3dlabs, Called and left a msg for bernie abou the others - hope its not to late - if so then I'll keep them and just stockpile them for my next build - thinking about making one for the ol'man he has more movies then blockbuster and an ancient TV.

ok The pic of the wall is what I have available for a screen. unfortunately I am a little off in the floor space or ceilingyou can see the mock up I made from a couple boxes which is ruffly standard LL box ( 12" high, 14" wide and 27" long - off a bit but close) [idea from LL forums]. Not sure what to do. Showed the wife and she doesnt want it hanging fomr the ceiling - and neither do i, but I want to maximize what I have. Which means if I have to go table top I'm going to order a haas if anyone is making, or cobble one to gether form the plans I found -

Going to suck it up and build my own haas style enclosure. Hass design


stay tuned ( might have to use cell phone to take pics because wifes camera + garage + power tools = cold lonely nights.

picked up the wood today, unfortunately I had to go with MDF because "they" didnt carry the right stuff and thier ply wood was _all_ warped not a streight board in the place. So what I'm going to do is us metal wall anchors ( they type with "teeth" ) for the screw in parts to make sure I get a snug & firm fit and wood glue on the parts to give it that extra margin of security.

I bought a sheet of 4' x 8' and had them cut it down to 4' x 18" (3) and one 4' x 2' was left.

I'd post pics - but who wants to see a pic of MDF in the garage

From my own wxperience Mdf can be difficult to work with and you may want to get some plastic wood to fill in the gaps (I did so and you can no longer tell there was ever a gap). The great thing about MDF however is how easy it is to cut through etc.

AH ok sweet - thanks for the tip

My new lens

JUST won it 30 seconds ago.

well I looked up the d800 and the case is identical.. now the only things is - how can I tell with out stripping it if I actually got the wuxga and not a wsxga etc?


and good eye there Hirudin.

It should have been clearly labeled where ever you got the panel (ebay?). They should have said what resolution it was at that point. As far as I know, unless you have an inspiron 8500 or latitude d800 to plug that panel in to, you won't know until you get your pixelworks controller and power on the panel.

it was labeled wuxga etc - just trying to verify I got what I bought - and not a Chevy with a Mercedes emblem.

Thanks for the feed back though, I appreciate it

I think that once you get the back cover off the laptop lid the LCD model number will be staring you in the face. You can look that up using the power of cyberspace.

But, unless the seller has like 3 feedback: I'd say it's fairly likely you got what you paid for. I figure for that seller's typical customer it would be immediately apparent whether it was WUXGA or not.

ok this is the template. If all goes well I'll use it. I'm going to cut then trace at that point


Hirudin -

Can I take the back cover off with out static concerns? Thats why I haven't striped it yet - hell its still in the bubble wrap

tacky to quote my self however I did it just the same for continuety - that said I aranged for the 650 fresnel to be taken off my order and the pro220 to be left on, I also have the a395a&b comming as well as that 18" & the s15.

question now is should I use a precon..

I wouldn't worry about static too much. I mean, don't carry it around wearing wool socks or something, but handling it shouldn't be a problem. Just touch something that's metal and grounded (like a computer case).

If it's like my laptop lid there's a bunch of little rubber spacer things around the LCD which cover about 10 screws or so. Take out all those screws and the 2 halves should split apart without much trouble. Inside there'll probably be 6 or screws holding the LCD to the back cover. Once you get them off you should be able to lift the LCD off and check out the back. ...This is from memory, so there might be a couple steps I'm forgetting... Anyway, check the model number and check the internet to make sure it's a WUXGA.

If you want you can put it back in the laptop lid again for safe keeping... The LCD assembly at that point isn't terribly fragile, but the more protection the better I guess. It might be smart to take a few pictures of the LCD before putting it back in the lid.

I'm going to list my inspiration from these forums here, its a bit late in the game so if I missed anyone I do apologize.

15.4 Wuxga lcd ( striped ) by Hirudin

Light review YEah baby,
more to come - be sure
Fun with the WiiMote (off site link from mad scientist forums - this is awesoem! )

ITS A SHARP!

Prelim assembly of the box - just cut it today and taking final measurements. It needs some serious massaging

more pics

A395 a&b are here along with the the Buhl 18"

Buhl 18"

more of the same

How did you come across that lens? That'd be sweet to find one with adjustment built in like that. I saw some old (labeled vintage) Beseler projectors on ebay I was thinking of getting...but they're encased in steel I think and cost an arm and a leg to ship, not to mention all I want is the lens.

spend 3 days on ebay off and on searching for 18" or beseler or projector or lens or any combination there of etc.

quick set up that I have to work with. still tweeking

another one as well

WOOHOOO er I mean OH NO!!!

After ruffley 8 years the 27" TV is starting to die - which will make the pj our only video display

me:
her:

Well, just wait for her to see it running (given that you don't break anything ), is you're room light controllable though????

actually its not to bad, during the day we don't watch the tube much - kids in school and we are out and about. Come dinner time and after its dark enough now and for this summer I'm making curtains. Thats why I'm using that room ( I just moved the living room in there for that reason. I can have the kitchen light on and even the dining room and it doesn't pollute much if at all. the room adjacent to the living room area is my computer room / office.

ps -

The drawing are acad and to scale - well as much as my current skill allows give or take 1/4" 1/16 or so.

got that btw from 3dlens. wish LL had these. Daz I also have an 18" now as well ( saw on ebay and couldnt pas sit up)

If you’re going to use the 18” triplet then you’ll need a front fresnel FL of around 520mm. Closest match to that is 550mm.

DJ

yeah I figured as much, I'm not going to use it right away - unless I really need to. It was just to cool to pass up. Its up the page a bit. You think with the 15.4" I should be ok with the 3dlens fresnels and s15 triplet?

now*(typo) I'm just waiting on the mega kit and pixelworks controller

I figured out the basic mount for the pj, 2 2x4stacked, braced by corners made form 2x4. the pj bracket will be re-enforced with shelving brackets. all hanging on 1" OD black iron pipe with washers and caps. going to proof the mount with my weight set to make sure the pipe is hard enough mettle for the threds to hold "dead" vertical weight. if all is go then walla

edit for new updated mount drawings

Well pretty much stalled until I can get the mega kit. I'm going to work on the fresnel / lcd setup, might not cut the fresnels and just widen the box a bit. Not sure if I want to cut them or not just yet.

Well I just handed my pj budget tot he vet, and then some to keep the old dog going. He was hurting bad, huge bleeding growth, and a lump up inside near his belly. They are both out now and being tested, he was pretty tender and I had to help him. he has a huge scare on his chest fromt he growth and a nice cut n' splice above his goods on his belly.

Hes recovering fine, and up and around. Its good to have him not yipping from moving. I wasnt about to put him down if I can fix the problem - so the pj is waiting. I'll make the mount and hanger on the cheap. should be less then 20 bucks for materials. thats in the HT plog now mostly. Hoping to have the actual screen and surrounding structure and shelving completed by the winter as I get busy this time of year anyway. I'll finish the pj + mount and just paint the wall white for now.

Glad to hear the pooch is doing better. My wife is a vet tech, and man is my house full of sick pets she brings home to help out extra. Hopefully they took care of the problem by biopsy.
Projector project looks good. Look forward to progess

Thanks.

I'm not giving up on the pj. never will. The vet is waiting on the lab results still. I just realized I could make a tripod for the pj to bring it places if I need to so I'm goofing around with that idea. most likely use the same type of mount for the ceiling but upside down or make the ceiling one semi quick disconnect which would be useful for maintenance anyway.

The thing with inanimate objects is that they'll wait. An unfinished projector will simply remain unfinished until you get together the time and funds to work on it again. The dog won't get better until tended to.

I agree with your choice of priorities. Looking forward to seeing more on the projector, when you can.

well today I managed to get the 4"x4"x8', the 3/8 dowls 3/4 dowls, 3/4" x 8 (x2) & coupler steel pipe with base (x2) and the brackets for the rafters. I had the guy cut me 14 lengths 14" and 18". When I got home I promptly went out and drilled the 18" and screwed it up with a crooked hole. So I do need a drill press for the holes in the 4x4. I have 2 bit and the second bit seems to be a straighter hole how ever I'll have to cut a new 18" section anyway so I'll deal with it then.

I did manage to proof my idea a bit - after drilling I put the pipe through the wood just fine - REALLY tight fit though so I might move up to a 1-1/4" bit because the pipe is 3/4" ID and the way the base mount best I have to fit the wood over a bit of a lip to be flush.

I'm to lazy to take pics atm its late. I'll do it tomorrow.

Well I bought a set of bits and managed to get the holes for the 3/4" dowels straight-ish ( no drill press I used a square) I cut them long, and mounted them up to test for fit etc. I need to cut to the right length now. I still need to make the sled. I'm using haas's schematics as you can see. A bit confused how the gravity keystone sets up.]

some minor progress. I spent money I borrowed from my self, and the 50$ blown at HD was well spent - progress wise. All I have to do now is cut the 2x4 to make the pieces for the frames and fine some 1/8 plywood - though to be honest I'm thinking of sacrificing the back side of the cellar door >:D - just a thought.

Left to do:
figure out what to use as top / bottom
drill front plate for triplet
create fresnel / lcd sled
drill back panels for the fans (2x120mm)
make a light box - or more accurately - a glorified heat shield.

the mega kit is due soon, fresnels are here, lcd is here, I have a 18" w/ focus for back up so I should be good to go other than the controller

well the wife has the camera attached to her so I'm having a bit o' trouble getting a hold of it for pics. I have everything for the sled accept the 1/8" ply which I dont want to buy a whole sheet for 2 11x6 sections. I'll figure it out. A buddy of mine had some fresh scrap 2x4 and that enough for the sled. its all drilled and measured waiting for the table saw.

The enclosure has the 1/4x1/8" dowels in and ready for the sled.

after the ply all the wood work should be done unless I need to tweak something here or there.

plans:
shower rod for shielding rear 3/4" dowels - great idea from a plog
black paint - everything internal thats wood save the sled
"light box" thats mostly just heat shielding the mdf and what ever I use for the top
now after I get the sled together its mount time until the mega kit come in.

quote simul8r

umm..... uh oh?

heh I have a s15 lens and a 220/330 setup in progress.doest this imply my 400w lamp will be choked by the s15? what are the implications of this? dark corners? tunnel vision? or the full brilliance of the 400w will not shine though negating any benefit from having the 400w at all?


for now I will have to "go with it" untill I can grab a 500fl collector fresnel for my 18" triplet

No Sim was talking about the Pro triplet with a 17" lcd.

Ah ok.

I was just jumping on real quick to say....

AAAAAAAAAHHHHHHHH!!!!!!!! I cant wait to watch my pj. Every time I grab the remote and want to sit down and find something to watch I look at the wall - then at the tv - then back at the wall and I can "see" the pj's picture up there dwarfing the tv and just kills the moment.

Well in retrospect I do have to cut the fan holes, and the lens hole. I'm going to do a light box with custom mounts after I get the initial set up done as I want to watch this thing I'm trying to think up a mount like the claw machine in the grocery stores. edit - ok x and z axis are easy - its the y axis thats throwing me.

what kind of adjustments are the most needed x and z? I have z and x pretty well conceptualized - however I'm not sure how much on each axis would be needed 5 to 10mm on both axis asuming

condenser fresnel (15mm) lcd (15mm) collector fresnel

I have the attachment to the frames drawn yup, not its just how to mount them out of the way.
