diy projector from the Philippines

[hertzblaster]

I am afraid before to try higher color temperature bulb because it might look like a presentation projector in which the skin/flesh tone is very ugly.

I was wrong. The skin tone, color saturation,brightness, contrast,sharpess improve alot.

Sun Arc (HSD )bulb color temperature 8000k
18,000 lumens 250w
arc length 5mm

This 7 inch lcd Ag is removed. Image sharpness is better than my LG1553s with AG still intact. Brightness uniformity is alot better.

I am preparing this to be used in a big church. Brightness looks so much better than Infocus x1 before. And near the brightness of our office Infocus 530 2000 lumens projector.

Hey bro,
Congrats on your success.

Nice to see that there's a lot of filipinos here.

Hope you could help me.. we are using a projector in our church but it did stop working. I think it has a bulb problem.

The price of the bulb was so expensive and I am looking for ways to use industrial lamp instead but I don't know where to start.

Thanks.

I'll be trying also to do my own projectors in the future.

Where is your church?

It was actually a Christian church in Solis, Tondo.

hey hertz, how did you get rid of that hotspot issue with the lamp arc you had before?

Was it just replacing the fresnel lens?

 

[hertzblaster]

Do you have this problem using your short arc bulb?

 

[giorgos18]

No, not me

Tescorp was having a similar issue with a 400W double ended lamp in one of his builds that it shows a hotspot in the middle, and I remembered that you had solved it. But I also am just curious to remember the solution

By the way, the builds you've been doing with the HSD lamps have been incredible. I've also seen similar 575w versions of the same lamp at the same price, but running those lamps are need extreme cooling

I just completed my 1920x1200 LG-Phlip LP154WU1. Cost about $400 to build.

Its very tricky to adjust for best color but i finally got it.

This pic if Angelina Jolee below almost scared me. She seems to be watching me instead of me watching her.

using cheap controller, when playing dvd on pc, like to be adjusted at high gamma and brightness setting for real colors and contrast to come out.

Wow, you have been busy. You have some excellant results. is this with just the 250W single ended bulb? I checked their site and I will have to get a few to test with.
Awesome results on the projector you built for the restaurant.

I was trying to find out info on the bulb from that link but the people there are so clueless about the products they sell, do you need a ballast to fire the 250W bulb? looks like you could hook it to a dimmer switch to knock down the voltage. I read that to get rid of your hotspot you turned down the voltage 5 volts which to me sounds like you have a dimmer switch or some way to adjust the voltage to the bulb.
Awesome results!!

Thanks in advance
