In this Instructable, I show you how to make a LCD projector with a LED as the light source. I tried to make videos of everything so it is easier to follow the steps.

After making my first LED projector that you can see here , I had lots of questions and people interested in the projector. Some of them went ahead and did something similar like mcastles.
I felt sorry that I could not give more details of the making of the projector. Also the MP4 player that I used is not longer available so many people could not find an MP4 with composite input like mine. I decided to make another one, so you could actually SEE how to do it.
This type of projector is very energy efficient. It only consumes about 41W. A normal projector with metal halide lamp will consume about 260W plus a DVD player which can consume between 20w and 45W for a total of about 300w. That is a saving of a lot of money by the end of the year. Although the quality and brightness of a conventional projector will be better, you'll have to pay the price, and the environment as well.
Another good feature of this projector is that the LED should last about 10000 hours of use wile a conventional projector lamp lasts about 2000 hours.
Lets see the result of making this projector.
