    instead of freshnel lenses I used a light reflecter from a torch light.
    magnifying lense and freshnel lenses both are different lenses for clarification refer to similar projects on you tube.
    if you have a slide projector lense you can try it in the place of magnifying lenses

    best of luck

    actually my thought is to prepare a 720p projector,so i took 800x1280 resolution monitor for lcd.
    now i am planing for creative 5.1 and curves Screen with white canvas cloth.
    for lcd,led,led driver,collimator, Fresnel lens-3,400.
    5.1 Creative surround system-2,400.
    So my total expenditure is Rs.10,400.
    i used my old pc cabinets part for Magnifying lens with adjustable focal length(i made a small setup for it).
    i have searched for a month and decided to purchase ol.with lower cost for all items.

    actually i am from,I want prepare a projector ordered all the necessary items except lcd in eBay,waiting for the arrival.i bought 15" lcd(Rs.3400).and the remaining i am giving in urls,can u make sure that my plan give good brightness.
