How to Make a Big Screen Projector

There are a number of ways to create your own big screen projector to watch TV. Watching a video on a large projector screen is like watching a movie on a cinema screen. The best way of creating a screen projector is to use an LCD projector that can be connected to the satellite or cable TV. For those who cannot afford to buy an LCD projector, they can convert an old TV into a projector by manufacturing a black painted cardboard. Before doing anything else, make sure you have enough space on a wall to lay out a projection image.

    For those who do not own an LCD video projector, they should consider assembling a black cardboard frame and tape it around the screen 2 to 3 inches out. Get a Fresnel lens and tape it on another cardboard piece. Cut a hole out of the lens and insert it into the square projector frame. Since the Fresnel lens is designed to invert the image, you will have to turn the TV upside down.

    For better sound quality and clarity, connect your video transmitter to a good sound system. Connect the DVD/cable box to external speakers if you are using an LCD projector. Although a television set with a cardboard projector produces its own sound, you can attach external speaker to it for better sound quality.
