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






Things that i used in 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 . 

  The basic concept of making pj is here -

    Very helpful review. Many of these questions I regularly use but you reminded me of some others - the prediction question and overcoming the urge in particular - which I shall revisit. Useful summary to share with on Projection Screen.
