Build your own LCD projector for Home viewing

[hertzblaster1]

"Anyway, I am still using an Acer 1170 DLP projector which is much better than ones found at CDR-King. Of course, costing nearly four times more, I do expect better performance from it than the CDR-KING projector.

Not everyone has the skill nor patience necessary to build their own projector or others simply prefer a more compact solution than a DIY projector can be."

I respect your opinion.

Guys share ko lang, para mas ma enjoy natin ang projet na ito,

Gawa kayo ng 3d glass, then mag download kayo ng ANAGLYPH MOVIES
sa *******s meron nyan,

enjoy!

Made one before, bought the parts from Rialto. Costs of DIY is generally the same as a low-end EPSON or ACER projector these days, but the hard work actually does pay off IF you get it right.

hertzblaster1 is not just one of the enthusiasts in these DIY projector projects. I've seen Russians build theirs relying on LED and producing the same sharpness as that of the bulbs in the original design.

In all actuality, there is a market for this IF there's a shop that could make it easier for DIYers to make their own box. It wasn't easy really for me to cut the glasses I bought from Rialto and it wasn't any easier to determine the center of the glass if you didn't have much of a construction basics course or what-not in Elementary or High School.

But again,there is a MARKET, and interest CAN boom - if only there are parts for sale that are already pre-cut and ready to install to a pre-made box similar to that of CPU parts being installed onto CPU boxes in a personal computer. Sayang din kasi, I've seen setups that beat the hell out of the projection capabilities of even the high-end off-the-shelf projectors these days. Just my .02.

try these french or american website. Some builders i envy because their workmaship is like a work of a professional. I hope I can build a very nice casing like some of them.

yung project nyo po ba wala nang kailangang adjustment, paano po kung sasa baba or nasa kisame yung projector, pano po yung keystone effect?

[ghosthunter]

*Ghosthunter

Sir kung nandito ka para makipag argumento, palagay ko nasa maling forum ka

kung di ka interesado at mukhang di ka rin naman bilib sa sarili mo na kaya mo ring gawin ang project na to, e sana po wag na tayong mag bad comments

para sa atin po ito, suportahan na lang po natin peace!

If you are pointing out if I am the one in the WRONG FORUM, you might want to check on your own words before going any further.

Peace or no peace, I fracking hate people who use "PEACE" as the last word in their message as if it means anything near to it.

PEACE!

keystone is very easy to do for small projector like when using 7 inch lcd. You can even eliminate keystoning problem with longer throw lens and a slight lens shifting of field fresnel.

yrralz,

The project I last posted got bought only yesterday even though its not yet finished and sya na lang daw magtutuloy tapusin.

I relented to his pleading instead of him building it from scratch because I still have one project to make.

I need to build ceiling mounted projector for my Bro's VIP room. I need a redesign to project 100 inches image size at 18 ft throw distance. I already have a design in mind.

I will start this project soon. Its expected to be 2 inches longer than the above projector but it will be a rectangular shape but the depth is only 5 inches.

keystone problem will not be an issue in this next design because the projector is kinda long throw one.

I understand you got your lenses from old ohp. I can help you if you will share to me the focal length of your lenses and pics will be of big help so that maybe we can salvage more parts in your old OHP.

How do you "finish" your projects? As shown in your pictures, your projects still have that raw plywood surface. Do you paint them or apply some sort of surface (vinyl or wood laminate) to look better?

[hertzblaster1]

Its the finishing . We have to make it look good because magagalit si misis.

vinyl is the easiest way to finish it, but need more sanding to smoothen the surface.

[hertzblaster1]

vinyl is the easiest way for a nice finish but you have to do some sanding.

Another important requirement for this build is the WAF!

Sorry MOD, nagmukha pala akong plastik dahil sa salitang peace?!

kaya ko nga po i-nedit dahil MOD pala kayo, kasi base sa argumentong nabasa ko inakala kong hindi MOD ang nagsasalita, kaya sorry po uli

*Hertz,

May budget na ko para sa project pero may tanong lang ako,

ano ano po ba talaga ang advantage nito sa mga commercial projector bukod sa mura?

Please compare

Brightness, contrast, color, gray scale, sharpness-compare to commercial projector

Maximum screen size at optimum quality-compare to commercial projector

Lamp life?

[hertzblaster1]

All are a very subjective comparison with my Infocus X1 DLP (IX1) 1100 lumens projector before. Infoucs x1 is still retains its popularity as the best all around projector for movies and presentation at a budget price.

Brightness- The 7 inch Diypj is brighter. Technically speaking, LCD trasnmits more light than the DLP at the same bulb wattage. But using bigger LCD say 15 inch loses more lights and IX1 is brighter than when using bigger lcd .



Contrast - My infocus DLP has advertised contrast ratio of 2000. But dont be fooled by this number. My diypj 7 inch can register a very pleasing blacks and whites also. But my LG1553s ( 16.7 M colors, 1400 contrast ratio) before beat the hell out of the infocus x1 in terms of color saturation and contrast. You must be aware of the lcd specs that you will use ot get good colors and contrast.

My Lg1553s captured images





grayscale- the 7 inch diypj can show very good shadow detail. my 7 inch diypj have an advantage here.

Color- my infocus x1 gives better color saturation . It also has higher numbers of colors versus diypj. But diypj since its an lcd gives a more accurate/real life color rendition. But then again using Lg1553s, the incosus x1 bows out.





Sharpness- IX1 image is sharper but you wont miss it that much as diypj can give a sharp image also.

The biggest advantage of infocus x1 projector - Very nice image smoothness and color saturation . The jagged edges is almost not noticeable even at close viewing distance, diy pj edges looks rough as jagged edges is noticeable. You will need to use a pc for diypj if you want to smoothen out the edges but still retain a very sharp image. It is because our lcd is not intended to be use for projector. But anyway at a standard viewing distance , this is not so much an issue

But i have one very serious observation which many poeple may have not notice. The infocus x1 dlp lacks three dimensionality feel.The image in the infocus x1 looks flat as like a plain picture. In many occasions i've watch my diypj, i can feel that the character in the image wants to come out of the screen ( quite unbelievable!) this is hard to believe. But again this is a very subjective observation.

Some scenes i captured. using 7 inch pj


Lg1553s



Main advantages
1.Total cost is cheaper
2. Bulb cost so much cheaper 1500 pesos 2000 hours.
3. Custom made to your need. Installation concern is always an issue for commercial projector for many people . Not everybody has dedicated home theater. Even if you have one now, you might still encounter throw distance issue to get your desired image size. I am not a fan of using the telescopic lens of the commercial projector as it losses your total image brightness by as much as 20 % if you are not aware how to use it, most likely most people are not aware of it.

4. Longer projector life- As compared to DLP commercial projector, it has a much longer life because diypj being an lcd has no moving part except the fan which can be easily replaced. Against LCd commercial projector, diypj still is better because diypj use an electromagnetic ballast that can even outlived your life. Ellectronic ballast just like a pc has a guaranteed life of 2 years.

5. You are even confident to left it running for 24 hours - since you build it, you know to repair it, parts is cheaper, youll have more peace of mind running it for longer hours hencem ore fun and enjoyment especially for parties where you can left it open thoughout the night.

One funny thing is, you can leave it outside if you want as long as it doesnt get wet. In my brother resto, he left it outside all the time and never bring it inside the house after using or even if it is raining very hard, the projector is still running and you can still watch . Its been running 8-10 hours a day for more than six months now and the bulb is still not giving up. But i am more worried about the lcd flat ribbon cable. it might get detached due to high humidity soon. My brother just doesnt care after knowing that the lcd cost only 3500 pesos. Its still very cheap because he is using it for business. He is just too lazy to bring the projector inside the house everyday.

[hertzblaster1]

And the best thing for commercial projector is even brightness distribution though still not yet perfect.

For diypj, this is not much an issue for watching movies. But for presentation purposes, you have to be precise in alignment of the light engine or bright and dark areas will be noticeable.

This is why commercail projector bulb is very expensive. The light engine and its lenses are precisely aligned in its entriely.

Good luck!'

old pics but right now may bubong na yang projector.


Blurry image because i cannot pause the dvd as there are customers




212 inches ( not 175 inches as estimated before) diagonal image size using 10.2 inch lcd

[claymore]

sir hertzblaster1,

Thank you po sa interesting DIY project...

I would like to ask if you could provide use with a listing of LCD (model/brand) that will work for this project..

Plan ko na po kasi mag assemble eh,

salamat po

[hertzblaster1]

visit lumenlab.com forum and search for compatible monitors.

[hertzblaster1]

Replace my 250w metal halide HSD bulb with 100w led.

Still using the same 7 inch lcd and lenses.
