hmmm
may be in excitement i posted my crude pictures too early.
i will refine, block all light leaks,play a DVD, pause it, take pictures & then post it & then we will see. i know that VGA or XGA LCD image is going to be better but my purpose is to watch movies only.
as i told, screen door effect was evident only when i was closer than 5 ft. obviously i am not going to watch movie from such a close distance.

people will ask , why i am experimenting with smaller LCD when others advised to use larger one. 2 reasons,
i had a small fresnel which could accomodate a sceeen no larger than 5". now 5" screen i coudn't find & didn't want to buy new fresnel, so decided to go with smaller.
second, i am a doctor. by 12th we all know human body in and out, but still in 1st year MBBS, we have to dissect dead bodies, then clinical examination on healthy volunteers and then on patients. so its a learning curve. same thing about PJ.
otherwise ,buying LCD projector and making a box and using materials and dimensions provided by others is, i think , much the same ( minus the cost)

i have repeated innumerable times that these small LCDs can be used for underperforming projectors.The PJ wouldnot turn out to be stunning for sure because of too large pixel size.If you wanna make yourself an awesome PJ try to go for the SAMSUNG's 10.6" WXGA if you could catch hold of,or else use 17" or 15" LCD. Mind it resolution had better be XGA or upwards.These days i guess the LCDs are available between 6000-7000 Rs.
PIXEL PITCH IS THE MOST IMPORTANT THING.

Dude if i knew the the availability of SAMSUNG's 10.6 WXGA(Mind it) then i would straightaway buy it Obviously at reasonable price though.Dear raise your budget a bit more to 6500 or so to build a reasobnable PJ or else compromise on the quality.Why donot you go for a regular 15" LCD monitor.See friend you are not gonna make it again and again.So Buy something nice which is presentable else your mother will say " what a tank(IMPOTENT with a poor resolution LCD) have you placed in the middle of the room !"Cannot you watch your regular TV.I think there is no point projecting an image thrice as large but with too big a box.
One more point these LCD TVs specify their resolution in DOTS not in PIXELS.So divide the number of DOTS by 3 to get the number of true pixels .

My friend , You have to options at your disposal.First is try looking for some LCD in NEHRU PLACE or betterstill would be put those fresnels aside for a while and get yourself the brand new ones.The cheapest would be from LUMENLAB.The safest and surest bet.I know you would not be able to save a lot my searching through the markets as far as lenses are concerned then there could be some quality issues as well.
Now the distances and all can be taken care of later.First gather all the parts.If you are looking for the LAMP KIT then i can sell it at 1500Rs.Its an OSRAM 250w POWERSTAR BULB with the ORIGINAL OSRAM BALLAST AND IGNITOR.Just plug it in and you would be ready to illuminate the entire town .In market it is availble upward of Rs 1950.Mind it everything is brand new and you can have any number of units.
