It can be done! A lot of times better than some commercial projectors.

Pls. support this pinoy site. Its the first in the Phils. but we are behind compared to other countries, but still we can make better diyprojector compared to some.

dude, why don't you make a business out of these for people who are technically -challenged like me?

i'm sure maraming bibili!

hertzblaster · « **Reply #8 on:** Feb 05, 2005 at 10:55 PM »

I have a full time job and pays well. That is why i can only sell some parts. Maybe soon if i have the time and especially financial resources . And besides my pj cabinet is not yet perfect. I still have to make a design on how to make keystone adjustment on the fly.

looking to buy a new projector for HT

looks great ang linaw

hertzblaster · « **Reply #13 on:** Oct 16, 2005 at 07:54 PM »

For diyers only.

hertzblaster · « **Reply #14 on:** Jan 09, 2006 at 09:14 PM »

Diyers never runs out of fresh ideas. The diypj is now as sharp and bright as some entry level projectors.

Removed the anti-glare film of my lcd and got great improvements in sharpness and brightness.

dulber32 · « **Reply #15 on:** Jan 09, 2006 at 10:21 PM »

hello hertz. nice improvement there.
might start into this project soon. can the parts be locally sourced now?
last time I checked (your site) a good lens can be hard to find.

more info requests to follow as I start the project

ah ok. thanks for the info.

moodster · « **Reply #22 on:** Aug 03, 2008 at 10:38 PM »

if you want 720p u can still do it probably add 5t more to the budget.

Huddaf · « **Reply #23 on:** Aug 04, 2008 at 04:56 AM »

Ayus to ah. Pwede na for 12k. Kaya lang wala akong tyaga gumawa. Sana chief meron kang tagagawa nito para pwede nating gawing business hehehehe.

ninjababez® · « **Reply #24 on:** Aug 12, 2008 at 09:31 AM »

does the 15k budget for 720p still apply (inflation)?

moodster · « **Reply #25 on:** Aug 12, 2008 at 05:14 PM »

20t pag 720p otherwise 15 inch lcd gagamitin mo. Double the size of my box. Look for lcd with backlight problem and you save alot.

I am in the process of making 1080p. My budget is 30t. Still ok because 1080p projector cost more than 100t

Anyway diy pj resolution is better than commercial svga projector because we are using bigger lcd. Magnification is much lower so screen door effect is non existent.

Ther are alot of bluray dvd copies now and svga diypj image looks like 720p

moodster · « **Reply #26 on:** Sep 03, 2008 at 07:44 PM »

Just got my 720p finished. Its big but has 10,000 hours lamp life.
Total cost is more or less 16T pesos.
But the results is much better than my diy svga projector.

nice screens, konting refinement sa kahon, oks na oks na, questions sir, how did you get it to become 10,000 lamp hours, special lamp ba iyan? and what's the throw distance? pag 10 ft lang ang available space, how big is the screen projected?

hertzblaster · « **Reply #28 on:** Sep 04, 2008 at 01:31 PM »

yes if i can make a very nice box, its gonna be very good for the amount I spend.

10,000 hours life is the advertise life of the bulb Osram 250wHqi-Tsd. Its a small bulb with color temperature of 5600k ( green to blue tint).

Most commercial projector has a color temperature higher than 5600k so it has a bluish tint. In higher color temperature bulb, flesh tone will look unnatural but color saturation and contrast is very good.

I have another bulb with color temperature 4200k and flesh tone looks more natural. you can see my pics in the earlier post but color saturation and contrast has much to be desired for.

The projector i made can project image size from 70 inches diagonal ,about 6ft from the screen to 150 inches
diagonal at a distance of 8ft from the screen.

The distances can be vried based on your design.

The real trade off here is the projector size. But i dont care about size when I am watching movie and lights off.
I used to have infocus x1 before, its nice but i hate counting the life of the bulb and worrying that it will explode anytime.Its bulb cost 20t pesos.

iiinas · « **Reply #29 on:** Sep 04, 2008 at 03:33 PM »

so how much is the osram bulb?
