Making LED HD Video Projector

Everybody wants to watch there favorite movies or sports on big screen. So they are plan to buy video projector. I also crazy about projectors. But there are too costly HD projectors available in the market. If you are looking hd projector in the market,there is starting price approx 30,000/- INR. It is very over budget for me. So i planing to make myself HD projector that project about 100" screen.
                                                                               After lot of research on Google i decided to make pj with 100w high power led and 7" 1280*800 LCD panel. The LED consume very less power and much life.

Here is the test result of my pj

1. Play wood (mdf) sheet to make box
2. Fresnel lens. I used 120mm fl and 185 mm fl
3. Triplet lens. I used 200mm fl
4. Condenser lens 
5. 100w high power led with driver
6.  LCD panel and its controller. I used 1280*800 7” HD lcd and controller.
7. 12v adapter for exhaust fan and lcd 
8.  Cpu exhaust fan to make projector cool
9.  CPU heat sink for led .
