Mix big screen home theater dreams with a limited budget and you have the makings of a great do-it-yourself project. Just think how impressed your friends will all be watching blockbuster movies on a video projector to think you've done with their own hands.
It was precisely these reasons, from my web browser digging for information landed on this project. There are plenty of websites that promise the moon and cheese to sell a plastic magnifying glass and instructionsglued to the TV in a box and put this lens on the front. You get a picture, but it looks like you have done alone. - Dark and blurry.
Is there a way to do this job? The short answer is yes. A projector is essentially a high-resolution LCD screen with a very bright light that he brings to the screen and projector. New portable models are very small and expensive, sophisticated LCD light sources and high qualityLenses. If you're willing to end up with a projector that are not so small, you can take the parts you need from a LCD monitor and add some electronic components and relatively inexpensive lenses. For $ 200 - $ 500, it should be possible for a high resolution bright projector to create really impress your friends.
The parties will need are:
High resolution LCD computer monitor Projector lens (and possibly 2 fresnel lenses used according to the plans for you) CoolingFan (s) - Light shining warm when you push them across in a box Source of bright light (to use a design approach to an overhead projector old) Power supply
There are dozens of websites with step-by-step plans for free or for sale. Some sell parts that you need. Two that I found very good and the DIY Projector Company LumenLab. Both sides sell and kits. LumenLab sells a very well done manual pdf with detailed plans. DIYIt offers free plans, but expect to buy one of their groups to the projector itself. Both use the LCD screen in a box with a light approach.
InventGeek has a great article about the whole process in depth the theory behind projectors. I recommend you try it. DenGuru The website shows a different approach to the project. They use an old projector in the lead for both the light source and the lens. To remove the LCD panel from the chassis and place it on the projector asTransparency. Ugly, but it works! Check out their tutorials.
Break your toolkit and get busy - and we're confident people out there!
