DIY : 100" LCD Projector with touchscreen functionality


INTRODUCTION


Yep you can build your own mini-home theater at a fraction of the cost of a conventional LCD projector. This project is rather fun and results are WOW.


Basically taking the concept of OHP (overhead projector) we can implement the same in case of an LCD panel, project the image of the LCD since the panel is translucent with ability to pass light through it.

What about image resolution?? Well you can get images projected with very high resolution upto HDTV and starting from XGA by using appropriate LCD panels.

What more a conventional LCD projector maintenance would cost much, a lamp replacement if burnt out would cost you 10k-30k whereas the bulb used here is only 500 rs. and that too with higher life expectancy.

Along with this guide I am also adding a small tutorial on how to make a projected screen (any LCD, projected image) function as a multi- point (4) touchscreen.

Fascinated? Enough of the introduction - let's have a look on things needed and how to build this particular projector.

Great stuff there dude!!!! infact if you could add fins to the aluminium reflector, it will aid the cooling of the enclosure.

Also, whats your take on putting a LCD above the normal slide projector and using that for projection?? dont have to mess around with the whole lens and distance issue??? just change the lamp to a white colored one, and give it adequate cooling???

If u can manage to get a normal OHP and mod it its very much possible but u need to source same. Another thing is the cooling should be very much optimized if you are getting an OHP and the i doubt you can use the 400w in that one cause the lamp itself is quite large and everything the lens center, triplet center, lcd center and lamp arc should be in one axis.

LCD Overhead Projector

this was what i had in mind.. your idea is surely more accurate and crisper in the picture reproduction, i am sure, and it would be brighter as well.. Just thinking about this, coz i have a giant wall waiting in the hall.. maybe use it for movie screening!!!!
