Really good video, excellent graphics. I have pulled a number of these projectors apart but didnt realise some of the details you explain. Im amazed at the MEMS mirrors and equally the alignment of all the parts in these projectors and yet they are thrown away with no appreciation of the incredible technologies in these devices.
Your animations are excellent. Great video! You should have mentioned the problem that appears with single DLP systems and color wheel or sequential led, which is the "rainbow" effect that bothers many people. While three LCD, LCos systems have the problem of RGB channel alignment. And you could already comment that in systems with DLP the micro-mirrors are not only updated sequentially for each color, they are also modulated in pwm to adjust the saturation of each color.
I enjoyed this video. I was a bit shocked that you said your projector is LCD as it most definitely is not. You have a DLP Pico projector. No DLP controllers would ever be in a LCD projector. But, your video was great with animations and really spot on in many regards. There are also single chip LCD projectors, which are pretty much garbage. Finally, LCoS projectors own the high end of the consumer market space as used by JVC, Sony, and even one from Epson. The ultra high end, as theaters use, is the three chip DLP. I’ve moderated Projector Central’s forums for years, feel free to reach out if you want any follow on work or ideas. Keep up the great work.
Hi, can you please help me to figure out the cause of problem with my projector? Its reddish tint color where it should be white. Its vivitek qumi q3 plus projector. Thank you
@@Sardeiuzz89 - It is best to look at FixItFrank's channel on TH-cam as I am not a repair person, but the most likely cause for a shift to magenta is a failing or completely failed green LED or processing that handles green in the projector. A lack of green = more magenta.
I am also an electronics engineering student and content creater here at youtube and look upto you and other great youtubers for inspiration thank you.
There is no mention of rainbow effect (RBE) artifact, which all single-DLP projectors produce. Some people never see them; some people see them but are not bothered; some people instantly get sick when they see RBE. RBE is very real, and along with any discussion of wretched single-DLP projectors, should always be touched on.
@@c1a9h9r9 RBE is caused by ANY sequential color system. Even if it's 3LED, there is still a single DLP. Most people fortunately don't see it; some see it and learn to unsee it; some always see it. Some very expensive projectors always have it. th-cam.com/video/yj0QveffCEM/w-d-xo.html
@@c1a9h9r9 No matter how fast the laser or LEDs flash, it's still sequential color, and RBE will always be present. Though it's true the pool of people will probably be smaller, some top tier expensive single-DLPs have very visible RBE th-cam.com/video/yj0QveffCEM/w-d-xo.html th-cam.com/video/EoqxZgyytj8/w-d-xo.html
Yeah. I have some medium and cheap DLPs. A few months of 6-8 hours of every days of using the best of these one and got a painful eyestrain and pain. But sharpness of that DLP is excellent.
Learn something new with every video, keep the good work!! If i may ask you for a little insight for my project. I cant really wait for the arrival of my GPS and GSM parts. So iwould like to know if it is possible to make an app with MIT inventor, that would listen to a bluetooth signal from arduino, and when it receives it, collect gps data from the mobile phone it is running on, and send that data over gsm network?
Great video! 3 LCD and RGB Laser are the way to go these days! Good to know how they both work. Keep it up! Got a "Like" from me! Maybe do one of these on Ultra Short Throw projectors? Not sure how much more or less different they would be than a regular projector, but I am curious to know more about them.
Wow- for a moment I thought you were joking when you mentioned the micro-mirrors... It's crazy to think that those are the first digital type of projection! Downright space-age compared to reels of film.
That last one reminds me of CRT tvs, a light beam drawing lines across the screen, or in this case a laser on a wall. If they could ever improve the tech to make full screen images at 60 or even 120hz it could potentially provide the best looking picture ever. Actual bright vivid lasers making up the picture would look phenomenal.
CRT used to HAVE 120 hz monitors before LCD took off. Even 240 hz and higher LCD and LED monitors today often compare poorly to 60 hz CRT in terms of reproduction quality and overall brightness despite the advances in detail density and fineness.
I know this is probably not gonna be seen but since your channel is all about electronics could you tell me where to self learn electronics online ? and is it even possible in the first place ?
great content.. I was curious about the other kind of Laser projector namely the picopro from celluon and the tears inducing beauty of the REDray 4K projector that never saw the light of day with some fantastic specs.
It is unlikely that the speaker module has an amplifier inside as mentioned. Besides not being practical from a design standpoint, your speaker only has two wires which are highly likely the two wires to the voice coil. It's also clear from the picture that the speaker module has an active speaker and a passive radiator to extend the bass.
But there is also chep projectors in the market that uses single coloured lcd to project image so why this projector has 3 Lcds for each colour instead of using single Coloured lcd?
I'm not aware that incandescent light bulbs have ever been used in digital projectors. (in 8mm / 16mm movie projectors yes) What you probably meant is high intensity discharge (HID) lamps before LEDs become available for this purpose. Also, the color wheel in a DLP projector isn't just RGB, but at least RGBW. Your animation actually does show the white segment but erroneously with no light passing through. These are just small things, but factual accuracy is quite important ;) The WOWOTO T8e mentioned as being an LCD projector although it seems it's actually a DLP one..? Good video otherwise! :)
I've just bought my first DLP projector and the rainbow effect is really crazy, I would not buy DLP projector again. You can get used to it after some time, but it's still annoying, it's like watching movie on drugs. I know DLP fanatics hate LCD projectors for worse contrast and lower brightness, but what is nice contrast for when I see flashing RGB colors on DLP? It's like some 19th century toy technology, not something I should watch movie on.
If you were to replace the dmd on this how do you remove the sealant / clear caulk around the cable on the lens assembly? If anyone knows plz reply I would be more grateful than you know!
Hi I really appreciate your videos, You explain things so well. Can you please do something about arduino and a good pi metal detector, I really hope to understand how this thing works. Thanks and keep up your good work.
Thanks, bro for the video. I have an Android DLP projector giving a message "NO SIGNAL". I opened up the product and confused about what could be wrong?
Would love to know where to source some of these "cheap" 4k LCDs. I can't even find any monochrome LCD with 1080p or higher that isn't at least 5" diagonal and lacking a UV filter, much less one specifically for projection purposes. Do you (or any viewers) have any recommendations? Thanks!
how abt a diy projector like diyperks did and it was on par even better than the commercial thing or even a laser show looking forward to it if u find it interesting anyways vry clean teardown and explanation also hope u r doing well
Hi, can you help me to point out the cause of problem with my led projector? Its reddish tint color where it should be white. Its vivitek qumi q3 plus projector. Thank you
Hi my friend, at first I would like to congratulate and thank you for the content and also thank you for the subtitles in brazilian portuguese. I have a suggestion for content: why don't you show us how to convert an LED projector to LASER? or how to convert a FULL HD projector to 4K? so far I haven't seen such content around here and I'm sure it would be pioneering. the challenge is out!
umm.. big guy just confused me is that your voice ? Nevertheless good video :-) You mixed up the LCD to DLP, the DLP don't use LCD to produce a picture the three LED is using DLP.
Hi im Projector Technician, i have seen Optoma HD20 and 23 model it has 6 segments color wheel RGBRGB, But how White color we get in screen. Is can get some video about how to replace the LCD panel and alignments plz.

No with the new tech, the RBE is cause by the color wheel, but now it's replace with 3 leds, that flicker really fast, so this effect goes to minimum.

Why not directly use white light through a single lcd rather using three RBG light if its still going to be white?
thanks for the info sir.

Great Video! I was wondering if you can change the resolution of the projector by changing the mirror mesh. 720p to 1080p or 1080p to 4K.
No. You would have to replace all the processing circuitry and software in the projector as well. Like replacing EVERYTHING.
Weldone bro
Se ve interesante amigo, tendrías más vistas y mucho más apoyo si estuviera subtitulado al español, no tendrías que editar dos vídeos

well explained!
It is unlikely that the speaker module has an amplifier inside as mentioned. Besides not being practical from a design standpoint, your speaker only has two wires which are highly likely the two wires to the voice coil. It's also clear from the picture that the speaker module has an active speaker and a passive radiator to extend the bass.
Exactly.
I was waiting for your video.why so much delay.btw great explanation.
Great video!My lg pb60g projector shows me yellow tint(white color missing).It means blue color is dead ,damaged or dirty...or something else.
Let's start electronoob manufacturer own product
I suggest a transistor based amplifier video , great work .
But there is also chep projectors in the market that uses single coloured lcd to project image so why this projector has 3 Lcds for each colour instead of using single Coloured lcd?
I'm not aware that incandescent light bulbs have ever been used in digital projectors. (in 8mm / 16mm movie projectors yes)

The light bulb or LED have a certain life time. Some LEDs after 10000 hours would stop working. That's life time

I like DLP, my lcd projector suffered from burn in I still use it like that until my replacement comes in.
What burn ?
So micro mirror chip is used only in DLP technology ?
By any chance was there a model number on the tiny LCDs?
They are custom made and no datasheet is available to the public.
