I remember not long after you posted this video, before I subbed, looking up how these works on Google. Found this video. Not long later, I stumble on your elevator videos, and subscribe. Little do I know at that point, that this video was made by that same elevator enthusiast. This is a VERY fascinating video. ;)
I thought the same thing (the facinating part), when I took it apart to see what was inside, and how it all worked. Good luck with the colored mirrors! :)
The light colors (Light-temperature/Hue/Gamma) can be adjusted on some projectors by actually slightly tilting of the splitter mirrors inividually inside a narrow angle so the resulting light behind the mirrors is of a certain wavelength or optical waveband. This is a preadjust setting however, the user-side color hue is corrected by electronics (intensity parameters of the three channels).
exactly! i hate dumbed down explinations. i wanted to know how a lazer works, so i found out how to make a p-n junction and got into physics just to know what right materials to use for it. i wanted to know how a capacitor works, and got into electrical engineering to understand how it stores its electricity. i take it to the max
You are not actually using a white light. Since the light source has a sort of yellow tinge, the clolors are not that vibrant.. and regarding the name of the color on the part 2 video, you should have print the name of the colors in the opposite color.. Probably yellow shoudl be printed in blue (I hope so)... Nice video !!
I was running out of time when I did this, so I would up rushing the color tabs, and forgot to do opposites for the color names (to appear in their correct color). I had an LED flashlight, but the incandescent was brighter, so the color is skewed a bit towards yellow, but it does the job. I'm thinking of doing other things with this piece of the TV, but haven't come up with one yet.
@KeithWasHere1 I'm not sure. There's an important piece that got misplaced (corrective lens to eliminate severe pincushioning), and some of it's housing is broke. Nothing a little glue couldn't somewhat fix).
@miro9963 No problem. I'm not a fan of those basic explainations as well. I found it interesting how the images are put together, saw nothing like it here, so I recoreded a 2-part video, and posted them.
It's not a video for short attention spans. It's rewarding to those that are willing to pay attention for more than a couple minutes, no offense. Society has got to stop catering to this problem. That's why things are utter crap nowadays.
What about replacing the normal lamp with a photography studio flash - in order to project an image very bright (for a millisecond or so) ... would the LCD screens be able to deal with so much light - would the image still have the right contrast etc?
If my projector displays yellowish image what do I need to change? Just the blue polarizer or a mirror too? And if i replace a polarizer how do I adjust it? Good video nevertheless.
I'm not too sure about that stuff. I was just curious about the optics when I tore this TV apart, and had to share my findings, since I didn't see any videos for this anywhere.
my projector has been taken apart five times.. cleaned everything.. i get a ghosty blue line on left edge, and yellow n blue color bleed. im just assuming the lcds are going bad.. viewsonic pj860
hey, i was jut wondeirng with the bulb inside the projector, if that runs off AC or DC? i'm looking at running my projector off an inverter... and if the projector converts the AC to DC inside the projector there isn't any point paying for one of the expensive pure sine wave inverters...
@sutadebastos It's eaither walk around, or scratch the table. I could pick it up, then have the parts fall out. Not much the winning situation. Look at it this way, you can pig out! :)
oh and to explain even further, im here because i wanted to know how to make a touchscreen table, then i wanted to make the projector. and after this im probobly gona go find out how those filtered mirrors are made.. lol
Oh, yeah, it takes a crapload of light to get anything good. A full-bright standard flashlight will make a 40" picture, but almost invisible, and ultra-faint white areas.
@KeithWasHere1 This thing is fairly useless now, as the one lens that keeps the geometry is currently "in hiding". I'm not sure about selling it yet, as I might do something with it. Not sure yet. I'll have to see if I can find that important lens first.....
@KeithWasHere1 If it allows blue, and reflects red and green, this particular projector won't work. :) (Yellow passes through the first lens, reflects blue.)

Cool. RGB.... There are some human minds behind this creation!
Multi-language response. Cool!
Thanks. Hope you enjoyed it.
Awesome video! Always wanted to know how it works.
muy buena explicacion!
very good explanation!
That horn is heard in several videos. It makes for good conversation, especially those who don't live around here.
Can't help you with that project. :)
I find it interesting how those filters work.
I'm glad that horn was from the fire station and not something else.

total cool " pure Newton " thank´s for a beem on that light ;-)
Good Job...., thanks for the awesome tutorial... :D

This is great video.
@sxcHideki
It was easier to circle around, so as to not accidentaly scratch the table, or drop the loose parts. The would be bad. :)
Have a good one!
It's a small world....Isn't it?
I wanna see a slow motion of the array of mirrors.

Oh, no, I don't have any of that stuff. Just the optics. The boards, bulbs, all long gone. This won't be any use to you then.
I'm not too sure about that stuff.

YOU LIVE IN THE CENTER OF LEOMINSTER! i can tell because of the horn! i live there also!
Funny thing is, there were no videos showing this stuff at all, and I searched to see if it was true.
hey, i was jut wondeirng with the bulb inside the projector, if that runs off AC or DC? i'm looking at running my projector off an inverter... and if the projector converts the AC to DC inside the projector there isn't any point paying for one of the expensive pure sine wave inverters...
No idea here.
E-Bay?
burn!!!!!! lol great vid

Look at it this way, you can pig out! :)
@COOKISLANDCHURCHGIRL
No tripod then, as this UA-cam thing wasn't normal activity then.
oh and to explain even further, im here because i wanted to know how to make a touchscreen table, then i wanted to make the projector. and after this im probobly gona go find out how those filtered mirrors are made.. lol
No problem.
@olger05
It's broken down so that the Non-Technical (Geek) will understand it.
@sankar2596
No tripod then, and I'd rather walk around it, versus scratching up my table getting all sides.
Oh, yeah, it takes a crapload of light to get anything good.

@georgef551 tanks for the responds :)
LCD stands for Liquid Crystal Display I think you mean DLP projector which means Digital Light Projector
@KeithWasHere1
If it allows blue, and reflects red and green, this particular projector won't work. :)
(Yellow passes through the first lens, reflects blue.)
Only thing I can say is yea it work but light source has to be over kill to get a picture which sucks.
Wow. That reflective property is weird.
@KeithWasHere1
Still got the whole unit here.
@joyofcreate
To an extent. :)
No clue. Sorry.
@KeithWasHere1
I think it was a "killer" deal, if you get what I mean.
I'd get the police on that guy. :D
6:00pm horn from fire station lol
really bad filiming , getting dizzy alot
Fuck, I bet you could build your own projector, lmao.
You sound like ferris bueller man..seriously, LOL no offence..
