Build your own home cinema projector

A few years ago, I used to spend a lot of time on eBay trying to spot attractive bargains for LCD screens and video projectors. Auctioning sites are an excellent place to find out about price levels and market demand but they also provide impostors and swindlers with a stage. In the eBay offerings you’ll often find DIY and step by step books that will tell you how easy it is to make a video projector yourself using only a cardboard box and an old LCD screen. Out of curiosity I decided to invest the $39.99 to purchase such an online book but, to my great disappointment, I never received it. Not only was I upset about losing my money but I was frustrated I wouldn’t get a chance at building the projector.

All this time, I thought the whole “build your own projector” was a scam and that it was technologically impossible to realize until I found this cool video on Youtube where you can see how to do it yourself. In fact, using an LCD monitor, an overhead projector, a cooling fan and a little of your time you can actually create your own home cinema projector.
You don’t need to spend a foolish 40 bucks, just check out the video to find out.

    I´m currently living in a spanish town where the only cinema available was closed a year ago and there are a lot of interested people in movies/cinema living here. I am thinking of opening one commercial cinema (relative small but modern) here and would like further information on this subject. It is a private project and somehow a challenging one.

    If you know Spain you might have heard about thelack of culture or facilities in those towns and I know that some people did build 3D cinema in Spain due to this fact.

    It is interesting knowing about how you can can use your LCD to build a projector.
    Well ,supposing you don’t have an LCD,but you have a television which is 14” and above then you can email me and i will show you how you can build a quality projector image 150” large right in your home.
    The beauty of it is that any image or device that you connect to your television can be viewed like a real cinema,all your materials can obtained from the house.

    Great video !!
    first sorry for my english
    I would like to know how big can be the projection taking in account the lcd size.
    I have a 22″ lcd with some dead pixels to use for doing this.
    There is a measure to know how big can you go without loosing image quality?
    I dont want an image with dark corners.
