Nice!!!! Gusto ko din!!!

Congratulations bro.,- I like the ways these technologies were fused......

hertzblaster1,

i use to troll around your web post in another forum... pero I never got start my own project.

ano "update" ngayon...

which ones works best?
okay pa rin ba yung "super" na 7" or 8" LCDs na being sold for a relatively low price?

[hertzblaster1]

Its hard to find 7 inches w/ vga input is hard to find. 8 inches lcd has FFC problem. some guys at tipidpc was able to remedied 14 inches lcd with ffc issues .

I was tempted to build 15 inches lcd because of low price and what I got also has the best specs for 15 inches lcd in the market today. LG 1553s. thought the box is twice the size of my 8 inch build, the image quality is much better. Now i have 720p projector.

You can find in the internet lcd with smaller size but price is about 15-20t for the lcd alone. Its out of our budget. So used 15 inches w/ xga resolution is still the way to go at this time. But if you can find 14 or 13 inch lcd w/ xga resoltion, then much better.

[hertzblaster1]

7 inches iw/ vga input still hard to find but you buy on line for $170. Still expensive. 8 inches w/ vga is sometimes available. Some guys at tipidpc was able to remedy the FFC cable issues.

I joined the bandwagon in building 15 inch projector because I was able to get cheap lcd with very good specification. Image quality is alot better than my 8 inch build though double in size. But its ok.

Question, where can we get the lens, light source and mirror for this kind of project? I'm considering something that looks like in this thread:

Pero syempre mas simple dyan! hehehe! Hardcore na kse yan sa ganda eh! hehehe!


Also, what specs should I be looking for in a used LCD screen?

ang galing nito... magkano kaya aabutiin sa gastos?

[hertzblaster1]

80% complete. Tapos na siguro tom

dimension is now 17x12x6 inches. Hopefully i can make it 15x10x6 inches.

Yes its alot cooler. But unfortunately led max temperature is only 60 deg C.

Water cooling of led becomes imperative so higher power led can be use. Its now on going. One builder is akready succesful with water cooling of led. I will try my best to duplicate and bring down the cost because parts are not locally available especailly the small radiator. Water block can be easily fabricated locally,

May I suggest liquid cooling designed for CPU's? At least use the pump and radiator that comes with it. Depending on the dimensions of the LED, you may be able to use the waterblock designed for the CPU as well.

I'm thinking of putting up a cafe or small eatery with movie projection.

admittedly I'm not good with electronics.

*hertz.. do you accept orders for your projectors? I'm outside manila btw.

if not, hingi na lang ako permission sa step-by-step procedure mo and ask a local electronics shop to do it.

echo ko lang ang tanong about focusing.. have you placed a focusing mechanism para sa projector mo? I've read through all 8 pages and I haven't read about focusing.

making a projector like this, dapat ba predetermined ang distance from the screen?

Do you have enough space for a DIY projector? A brand name projector (Acer) can cost in the mid P20Ks and it's small enough to hang from the ceiling yet powerful enough to be clear with ambient lighting turned on.

I'm outside manila btw.

Yup, Leviticus is from Benguet so certain special parts might be hard to find.

I had lots of offers to build but unfortunately i dont have the time.

You will lose the advantage of diy projector if u dont build it yourself.

For indoor installation, based on your skills,I guess commercial projector is good for you but you have to live with expensive bulb or problem with parts availability bec each projector model are phased out quickly by manufacturer.

For outdoor installation, I guess DIYprojector is your best choice. Commercial projector cannot withstand humid condition. Regular cleaning once a week of lenses will be needed so you have to build it yourself so you know how to service it.

You need to know your target image size and throw distance. I designed my bro pj in his resto with 212 inches huge image size at a throw distance of 22ft. Bulb exceed 2500 hours running 8-10 hours a day before it died. I replaced it with bulb that cost only 500 pesos and still works perfectly (Lol!). The bulb is still a short arc bulb ideal for projector not the bulb the cdrking uses.

Manual focus is enough for fixed installation. You dont need to spend in expensive zoom lens for fixed installation. Most commercial projector Zoom lens can enlarge or shrink the image, correct me if Im wrong, by about 20% only. You will probably use this zoom lens once for fixed installation.

You need more a carpenter rather than electronics technician. Basic electricity understanding is more than enough based on builders experiences.

Btw, What is your target image size and throw distance ? Indoor or outdoor?

This projector has progressed already by using high power leds . And for special individual with expertise in water cooling has unselfishly shared his knowledge and now we have water cooled led projector that helps gain more brightness and have longer led life. I have a collaboration with this guy and later improve on our design and understanding for water block designed for led only and also we are able to specify what is the optimum parts rating that is enough to cool the led. Pretty exciting! Still cheaper than commercial projector . Now this idea is for free for every builder to implement. Led life is 50,000-10,000 hours as advertised by manufacturer.

You might have have special skills that we dont know and hopefully it can help contribute to this project.
