projectors
Has anyone tried any of the Opaque projectors with an lcd monitor or screen?
i saw one this morning during a meeting... our project engineer has HIS OWN opaque , he took a colorpicture, put it under the projector and there was a 4ft picture on the wall.
it has an interesting feature, the size of the projection is determined by him as there are 2 frame sliding mechanisms.
he moves the upper and lower part of the frame in one move and the left and right side of the frame in one move, so that pictures are always tightly surrounded with a frame, leaving no extra light on the wall. Costed $150.00 according to him and was brand new, not refurbished. Looks great though brushed and black steel.

Opaque projectors
I built one a while back to see how they would work for our needs. Not to good Im afraid. See the light has to pass through the LCD twice this way which causes glare and some focus problems....also makes for more heat on screen. Also you need alot stronger light source for this method- the oposite of what we want. See a real image being projected the light doesnt penetrate the surface like our lcd's. With them the light is of course passing through the panels pixels. But this is now happening twice. So two times it must shut out light for black to be black and etc so it hurts the contrast ratio aswell. Twice the work, twice the light, twice the heat. You can try it, but it didnt yeild anything for me.🙁

Re: 2nd projector
Uvodee--You only charged $225? Wow. It would cost that much alone just to buy the parts (once you add shipping from 5 or 6 vendors). Do you have plans or pics of this model? I've been trying to use my 5" Pyle LCD screen (very similar to the L56M), without too much luck figuring out lenses and such. If you have a parts list and/or plans that you'd be willing to share, please let me know.
Thanks,
Anthony

nec lcd
for those who are trying to use the nec 6448AC33-18 lcd without any luck to find the right set up between lcd and vga card (or svga) , it am not 100 pct sure but i think strongly that the SHARP LQ10D32A is exactly the same 10.4 " display after comparing tecnical notes and data sheets.
Apperently the whole set without the display can left and right be bought for less than $200.
the NEC display has been for sale on ebay for $0.01 and the woman said she had 100s . That was some 2 months ago i think.
Anyway maybe for those it can be of any help i think that earthlcd sells the kits.
I did notice that the the amount of colors does not run in the million so i think that is kind a weak....
i should have known that those lcd panels came from one factory !!!!!!!!!!

the pyle and legacy i think are basically very much the same.
(there are 3 more that are similar but i can't think of the name right now) but i think you bought your's at 'Judy's" right???
if you pay more than $70 for this stuff you are being robbed!
they go for $25 (each) back in their homeland!

6-pin Din Pinout
Uvodee--
Paid 80 for it, and can't remember where I bought it. Some shop that auctioned it on ebay. It's not a bad little screen, but it may be time to move on, in which case this one would make the perfect project screen.
Would you mind sending me your plans? I would gladly reimburse you, particularly if you have good places to buy everything. At this point, I'm still toying with the idea of buying a prefabbed used projector. Other than building computers and rewiring my electric guitars, I don't have too much experience, and the more I read, the more this all seems over my head.
Also, does anyone have the pinout for the PLVWM 5.0" pyle panel's adapter? It comes with a "serial" style connector that provides the video signal & the power, and I'd like to leave it in-tact, if possible. It is a 6 pin (+ 1 "plastic" pin) DIN format. Is this standard?
Also, what type of lens should I get--I was going to get a Delta IV, but I've read that's not the best bet. Is the Fujinon from the military surplus store more "flat"? Sorry to sound so unintelligent about the topic, but I just started reading through the numerous posts here...

all my plans/pics are in Yahoo groups, lcdprojector under photo's and then click on jpsprojector.
mine is a but different than most others, it takes too much time to explain. let's just say that you need to read all older messages and after that think i am the 'enfant terrible' on this board, which is ok, i have a very lovin' wife! hahahahhahahh
any more questions about my project , just ask or alos you can go to zark's website! simplicity in itself.

cheap projector i hope
first this forum is great just started reading yesterday was doing research on hooking a small lcd to a svga card and found this now i want to build one.
can any one give me a straight forward link to plans for one
my idea iis to recycle my old dark room enlarger has all the basic parts and lamps are cheap like $60 a bulb or may replace with leds but need full specs on how to configure and also
any one know how to propaly conect the lcd to s-vga if not rca would do my radeon card does have rca and s-video so not brob but would love s-vga🙂

forgot by useing enlarger gives me a bellow focused lens with apature adjustment🙂 (can adjust amount of light thru lens)
and lens are interchangeable so can switch lenses and light allowance depending on different enviroments

i failed at all atempts for perfection
yo i did so many thing and got so close . i think the most i could pull out of the 400w mh was when i funnelled the light but of couse that cause blurry edges on my projected movie. im out of ideas for the 400w mh except for one more very last atempt.thats to make a lens big enough to catch all the light coming from the 1/2 spheare reflector. the idea to make the lenscame from one of those glass water balls with snow flakes (they act like a lens to) i was thinking of using a flat peice of glass on one side than using a warped peice of plex-E glass on the other side.then glueing then to getter.then drilling a hole at the top of the lens to stick a hoes in so i can fill the lens with water. the hoes will also act as something to releave the pressure from the hot water.maybe i'll have the hose runing out of the projector box. also some other thing about this lens,is the water will act as a ir filter, temper glass can handel more heat , i'll probly use a heat gun to form the plex-E glass, and most of all this water lens can be very dangrous if leaks or breaks.
if that dont work im selling my light. and i might quit this project, or buy a broken projector and fix it, and or i might do what undreem was talking about doing and getting a 1000w mh. i think his thorey is correct and then the only potential problem we'll probly have is the cooling system and the wiring of a saftey plan so if the fans or what ever cooling sys. goes out the light will turn off to/ so theres not a melt down or a fire in the house.

do not give up that easy !
gee, the only problem you are facing is the lens and you do not wish to go ahead?
1) i went against all odds and used the fluorex
2) i used 1 plastic fresnel
3) against all odds i used a delta IV or 67 depending my feeling
4) i had to overcome so many problems by using the cheapest lcd on the market ( had to connect 50 pos. spread over three wires ( i had to keep them the same length and they could not exceed a certain lenght ( 5" ) otherwise NO PICTURE
and still i went on and succeeded! come on maaaaaaaaan.

uvodee-
I don't really know whether your projector works because you have not posted a screenshot yet. I asked you for one a long time ago, but you never put one up. I have serious doubts about the flourex setup, especially with so many people saying they couldn't make it work.
I managed to snag a 3M 9550 off of ebay, and that is the final piece I need. I am going to use the optics directly from the OHP (which are matched to one another) and my 400 W MH bulb with my elliptical downlight reflector. Hopefully I will have it going in a few days, depending on how much time I can put in.

where did you get your elliptical reflector? Can you get us a pix of it? I'm putting together a similar setup as you with my 3m ohp and 400 MH ed28 bulb.
Thanks

Hi-
I got really lucky. I found an elliptical downlight on Ebay a couple of months ago. I picked it up for $20. I don't really have any leads on where to get one for people, unfortunately. Keep looking on ebay though, they do sometimes show up.

Lowes and Home depot have light cans for MH track lighting. Some of those are eliptical. Go with one though deseigned for spot lighting or spot track lighting. These give a much nicer narrower beam like 10-20o. More is aimed at the panel that way.
Re: do not give up that easy !
I too only use one fres. I have 3 BUT the pic gets birght in the middle and dimm at the edges when I usemore than one. Just one before the lcd has given me the best pic.uvodee said:
Thanks Tinker.
I'll go to a local HomeDepot this weekend and see what I can find. Lowes is a bit too far for me.

well in all honesty, it (they) work really well)
the reason why I did not post any pic of the projection is i do not get any picture taken from the result i guessthe camera i am using AIPTEK pencamera is not suitable for this kind of dark situations at the amse time i took the camera with me to a movie theatre at gateway center in Federal Way and it did not work there as well ...
i am trying to find a solution with some better camera...

ithink i no a way to use all the light from a bulb and send all of that light striat in a paralel beam. no reflector needed . do you want to no about it. it will need a crazy cooling system, thats the only down side. no i have not tryed it but logicaly it look to me it will work. it will take some time for me to draw it out in 3d so you guys can under stand how it works. so unless some one wants to know im not gona bother telling or drawing it. i have a feeling nasa would hire me just because of this idea.lol.
i have no money to test it out etheir.
