Hi Friend, I am Sanjay from AP .I am experienced in building projectors. Mention me what the size of your lcd is ? Are you working with a small 7 inch LCD or a 15" LCD monitor? It decides the lamp wattage & the type of box you need to build... Up to me i like making pj s with small 7" LCDs because they are compact than the counter 15" ones..

Hi Sanjay,
I want to build a good quality LED projector. I am from Pune too.

Reason for LED over MH is due to costs/heat savings.

Also I want to build under Rs.10k/-
I know the basics but never tried it out. How do you suggest I go ahead?

Thnx.

Hi Innocuous,

Its almost impossible to build LED projector within Rs,10k, LED SMD( chip) itself cost your 2800 (here) after this you need a water cooling system, for this you need a Radiator and other parts which again cost you aroung 1500/- after this you need atleast 7 inch LCd which cost aroung 3500/- Fresnels 1000/- nad Triplet 2000/-

this the minimum config rate i have given you, if you wish to go for higher config like for 180 triplet, then the rate again will go high.

You may need atleast 16k for LED

There is no cost advantage in going for LED in india. You can do a MH 250W projectior with 10K

hi parikshit...if you are intersted to biuld led pj..pls chk hertzblasters website.he is also in diyaudio
diy projector from the Philippines.
he is the most successful one in led diy pj.
btw are your led 10 watt only.I am afraid they are useless in this field.at least 100 watt composite led (min 8000 lumen output) alongwith heatsink/water cooling and proper adaptor/power supply should be used to make a led diy pj with good image quality.
just google 100w led and heatsink.you will get lot of info.
and please question anything,I will help as far as I know.
by the way I am also building diypj with 10 inch lcd and 250 watt bulb and also from india..kolkata.
