I made a projector like that but it was a little before HD times, and those bright LED even were available to us, so I used a Metal Halide 400w lamp (the dot one) and a Panel from an LCD Monitor, it worked marvelously well. Now, I learnt a few things, one of them it was that the Source light should be as Small in size as possible, that translates directly in how Sharp the final picture on the screen will be, that LED you have there is way too big for the sharpest image, nowadays there are quite smaller/powerful LED units out there... thank you anyways for reminding me about all of this, I think I'll give it a shot with new technology! cheers!
thanks for the sharing, i will definitely get a small powerful LED. You mentioned that you learnt a few things, is there anything we should take note for a sharp clean video production? Cheers.
Really great build. Might I recommend painting the interior of the projector flat black? It will cut down on stray light and make the projected image clearer and give you more rich blacks.
Thanks, good idea
Very nice build!
So lately I"ve been wanting to build a pc case out of wood. so I"was wondering is that type of ply wood any good for this purpose?
BTW Liked & Subbed!
can u help me understand how the led light help illuminate the screen which is then projected to the screen through different lenses. I didnt understand how light from the LED get past that screen
HamiNepali also if your lucky, you can look on ebay and find them stripped down already.

Cool, Dracula is building a Projector!
Lol😆😆😆
because you can,t do one lake it?? bee a dracula and let see your works 😂😂😂
you could buy one that's really expensive, American brand made in China , or you could get on a website that has Chinese projectors with descriptions that conflict with technical details, or blatantly lie to you about the details, or buy the cheap but good Chinese parts and build it yourself like this guy . Great job, I love these types of instructional videos.
Amigo, este é o melhor projeto de projetor que vi na internet até hoje. Parabéns! Rio RJ Brasil
it's not about making a projector to replace something you can't afford. its about the of making something out of nothing and spare parts I think it's awesome. in the experience of doing something and making something
i am so glad to see someone else who actually understands the hacker mentality. i have gotten into so many arguments with people who just dont get it
Exactly!!
James Bryan yes, I sometimes make things just to make it and I enjoy using it but sometimes I put it away so I can make more and get judged for it. Once I even explained this and they just called me a hoarder 😂 I'm 12!
wood vs electricity vs heat! Gotta love the combination!
Great job. Having tried a projector with a single mirror and smartphone with marginal results, this is really incredible!
This comment is for the ones who doesn't have knowledge and diligence!
It is not just about saving money or time, It's about proving to yourself that you can do it !
Great job thank you for sharing
I've been searching to find someone using the 100 watt LED module and you're the first! Nice work, I'll be watching you in the future, best of luck to you. Looks like you're almost there!
Is it important to put a fresnel lens in front of the lcd display? Can it work without it aswell?
Simply the best explanation I've ever seen about DIY Projector. Thx a lot... 👍
Is that a mechanical toomstone setup? Im impressed even most commercial ones dont do that, they just end up chopping up the image from the available pixels...
There are lenses and optical windows that absorb heat (infrared) but allow the visual spectrum to pass through. You could use one of these between the CREE LED and the LCD (with a cooling fan that cools both the CREE and this lens/window) to keep the heat from reaching the LCD screen.
where can i get these lenses please?
I feel so calm after hearing his voice.
Wow, didn’t expect such a high quality result from that. Very well done.
Do you need cooling fans if you're using an LED?
What is the prices that you give in description is it really please reply
You are a design engineer... Good work 👍👌👌
it is the most amazing thing that I ever seen in my life.
WOW!! one of the best DIY projector tut.
How do I know where to buy the right good quality fresnel lens? What should I pay attention to before I buy?
I see that you are using a 300mm lens, is this the right focal length or are they other options. And if you use another focal length is it also necessary to use fresnel lens with another focal lengt? Is there a calculation table?
This is awesome. I have built myself a beamer about 15 years ago, same technique with a 7´´zoll Display fresnels, a surface mirror to reflect to the lens and to shorten the casing and a lamp with active fan cooling, don´t remember the name but it was used in stadium lamps :D The ballast for the lamp was so great, that the beamer was about 25 Kilo. Pretty awesome in result though. We had outdoor cinema very often with neighbours coming over and the side of the house as screen. I´m really tempted to go for your build. LED ftw I have used a focal lens and a much bigger lens for the stray of the lamp itself to even out brightness. The resulting picture could be adjusted from 1.20m to about 3 meter square.
well is really interesting to see a much better quality in this DIY project than many expensive good branded projectors out there.
WOW I did not expect to see such quality of video come out of this thing... very nice!
please tell me ---- distance between led chip white plastic bracket and condenser lens
Hey genius person just a small question from a small fan sir please tell where we can buy the main lense in low price of 3 to 4 dollar please
so yeah... is it cheaper du buy a HD Beamer or to build this?
Hello please can I get the full details of this project. I’m constructing a projector as my final year project.
Hola el lente de un proyector LCD panasonic ,es compatible para adaptar a un proyector casero?
how to make projection lens. I searched a lot but not found any tutorial. what is the substitute of buying projection lens? Because only with convex lens I am not getting the desired output.
Nice, I like this projecter and like projector clarity
This is about concept of learning the invention which is work that he did!I like it !
This tutorial is just what i was looking for. Really amazing projector. I was tired to see phone projectors. Thanks.
Thanks bhai...
You are Genius...
One should have good knowledge about electronics to make such things... thanks.
Awesome! Though I'll still buy one instead. What's the average price of this quality made by the A-brands like Sony you think?
you are so genius and good technician
Just great! How much does the whole project cost? The used camera lense is not a cheap one.
The whole project cost me around $ 100
+HAMMERLAND Did you choose lens based on focal lenght? Or something else?
Линза была выбрана каким образом? Потому что она использовалась с крупноформатной камерой? (моя логика говорит, что у вас матрица 7", что явно больше типичных 35мм и обычная фотооптика работать не будет - при установке на правильном расстоянии будет проецировать только центральная часть экрана).
A very nice project.
I build my first overhead diy projector 15 years ago - mainly the same principle, but no lenseshift, lower resolution and the original lamp (15€ and last only 50h). The cost of the lamp was the main reason to abdon the project that time. Now I think about reactivating the old project...
One possible improvement: Part of the heat at the display comes from the first linear polarisation filter. An LCD contains of one linear polarisation filter, a colour filter, the liquid cristals between two sheets of transperent material (with the contacts inside for the electrical field) and a second linear polarisation filter, right angle to the first one. The first polarisation filter blocks 50% of the incoming light - and so produces heat. The liquid crystal turns the polarisation about 90 degrees (no electrical field), so it goes straight though the second polarisation filter.
Ist there an electrical field at the part (pixel) of the lcd, it stops to turn polarisation, so the light get stuck at the second filter.
So there is a quite simple solution to protect the lcd: extra polarisation filter between 1st frasnel and the display, so the light gets pre-polarisied to the display. So a big part of heat is blocked before the light gets to the display.
Of course, an IR-blocking filter would help also to reduce the stress the display gets.
The lensshift is a very good idea. How exact does it work? Would it be possible to build two projectors setting side by side, projecting at the same spot?
The reason I ask: 3d-Projection. There are some possible ways:
1. Linear polarisation
As the display has already linear polarisation, using 45 degrees. At the second projector, you simply change front- and backside of the panel, so you get -45 degrees (or 135°). Of course, the picture has to be mirrored on that display to get ist right. Or you use a blank LC to rotate the polarisation of a normal orientated display.
Fitting glases for viewing are used in some Imax cinemas
Silver-wall is needed for projection
2. Circular polarisation
This is done by using a lambda/4-filter (lambda of green colour, so blue and red are not exacly circular but "egg"cular...). It reduces ghosting if not sitting exacly upright.
Same as linear polarisation, but adding a lambda/4-coil between display and objectiv.
Two versions:
2a) both displays normal orientated, but lambda/4-coil on one display -45° and on the other +45° (to the linear polarisation, so 0°/90° to the axis of the display). This is the principle on zalman Monitors (so you can use the glases for them)
2b) like 1) orientated displays, so lambda/4-coil has the same oriantation on both projectors (0°/0° or 90°/90°). This is the Real3d-Concept, so you should use that glases to watch (cheapest solution)
Silver-wall is needed for projection
3. Infitec/Dolby3d
Infitec is an colour filter system using interference filters. Simple spoken: one glas only treepass the left part of the blue, red and green spectrum, the other the right part. So you get full colour on both eyes, but different wavelengs. Due to the sensitivity of the eyes todifferent wavelenghs you have to do different colour corrections for left and right projector.
This system has some disadvantages, but (in my opinion) some very good advantages:
Disadvantages:
- Licence Politic. You normaly can not buy filters and eyeglases, you first have to get a licence (expensive), then you can buy them. But there have been dia/slide-projectors with this filters, so sometimes you get luck. Also some early 3d-monitors with this technique were sold, so you may get filters and glases this way. I had luck and got a set of filters and two glases...
- Only 7% of light gets through the filters, 93% are reflected (not absorbed, so the filter do not get hot)
Advantages:
- The filtering is done before light gets to the display. As the maximum heat the display can endure is normaly the limitating factor, you can increase the light output - 93% will never reach the display. If your projector normaly uses 100W LED, you may use 1000W instead (or a plasma bulb...)
- The glases use the same filter. So external disturbing light ist also reduced, while the light from the projector gets fully through.
- You can use a normal white wall. No special silver one...
Dolby3d is Infitec, but left and right changed. So if you can get hand on Dolby3d glases, simply swap cables...
- As the filter reflects all unused wavelenghs, you may use one lightsource for both projectors - the "wastelight" from first filter contains the wavelenghs the second needs.
The main reason for building an diy-projector in 3d: the technology normaly used makes headaches. The left and the right picture are sequential shown, so one eye gets picture, the other dark. In homecinema you use normaly a shutter glas. But also most cinema use sequential projection. Real3d uses an LC (the whole LC is one "pixel") to swap polarisation 0°/90°, folowed by an lamba/4-coil; Dolby3d uses a colour wheel between lamp-unit and projection-unit. With a selfmade dual-projection, you can solve that problem, showing left and right picture the same time. And Infitec/Dolby3d is only possible with selfmade projectors (or very hard modified commercial projectors), as the filters must placed in parallel beam...
As for the displays: of course a nexus7 is not ideal for external sources (it is perfect of course to stream 2d Video, surfing the net and so on). There are some displays with hdmi available, using full hd at 7 inch. They are made for cameras. Lilliput A7S 7-inch 1920x1200 IPS ScreenLilliput A7S 7-inch 1920x1200 IPS Screen cost about 150€
Which lens to be use Front of the projector *(black lens) -camera lens plz share more details about that lens i purchase all material excl. This lens ...??
If you cover all four sides of the LED compartment with reflective tape or mirrors, would it help with the brightness?
The effect would be very slight
Interesting. How did you solve the charging of the tablet's battery?
And I'm still waiting for part-2 of this video. Please make it soon.
Really very clear and good picture quality.
Hi I think this is great! My question is : is the LCD screen see through ? I know you showed pics of you removing stuff from it but I didn't see the LCD transparency. Because when you showed the end result the image brightness looked very low.
Edit: I'm dumb, I didn't see you had made this a 2 part video and 2nd part explains the brightness.
Reflective mirror lcd used here this mistake is results inlow brightness avoid reflective lcd panel used transmissive lcd panel which is transpernt there is 3 type panels reflective. translflective. transmissive. so no one think about this u r question is right bro
Groove side of the Fresnel lens is facing LCD screen or led light?
pls can you update list of thinks what I should buy and where
i am confused at 2.54. do we want remove complete backlight and make the lcd transparent ? or keep the mirror finish
I got into DIY projectors because it was a cheaper method. Now I just like the idea of making my own granted the quality to price ratio is good. I recently got interested in triple LCD. one LCD for each color, should and a light for each of those
Kind of a pain, but in the end, this project was worth it. Thank you. You're awesome!
Well done, I will build this when I find out how to acquire a flyback thingy?
Can anyone tell me what item might have one of these inside so I can harvest one for this project?
Thanks and peace from Ireland to you all.
Wow awesome 💯🎉👏
This project is much harder than it looks(or he is just lucky). Optics are hard to deal with and you often end up with uneven lighting on the screen or very low brightness. Great build!
In fact, if you understand the theory, everything becomes simple
the best title is how led video projector works..? you can reach more peoples..thank you..very good workd
from algeria 👍👍👍🇩🇿🇩🇿🇩🇿🇩🇿
Omg veryyyyy veryyyy veryyyy nice , pro man 🙏🥳
can you help me to strip my lcd??? I dont get it.. what will look like if i stripped the lcd? it is color green glass?
very good job. Could you use a smaller focal lens? what result would it have with a 75 x 75 focal lens? if I decrease the focal lens do I have a lower magnification? please consider providing subtitles in Brazilian Portuguese.
Hello
What is the other circuit boar for ?
Below LED Driver board
hey it's looking very amazing & i hope it is. I just want to know if i don't want attach nexus table.So what can i do if i want simple projector with these options (USB, VGA cable, HDMI, chrome-cast android usb).
I have a question... If you can do that with some wood and projector components, is it possible to turn my an old 800x600 projector (Viewsonic 55134) into Full HD just changing the internal LCD display? That would be very cool!
You need to change the LCD display and the display control board
HAMMERLAND interesting... Do you know how much money would that be on aliexpress and how difficult would it be to do it myself considering I have no knowledge about it?
Just one word to say, WOW!
This is super cool and images are very clear than cheap chinese projectors!! How much did it cost you to build this DIY projector?
140$
What is the price of this lens and display please say
why dont you position matrix between fresnel lenses ?
orelse can we use any focus lens of other projectors? plz help me out plz
Please tell me the lens and accessories u hv used in making the project
Is Idubbbz talking in his European accent? :P
Nice video mate!
LOL
Can i by chance make it smaller? I mean is it feasible?
how did you get the glass part off the screen without damaging it? The glass of the tablet face and the screen assembly appear to be fused together.
Please tell me What lcd used on this video?is that tablet lcd or phone lcd?
As soon as i finished this video i subscribed, you are genius and i hope to learn more from u
I found an led reflector, 100w and more cheap to use instead of led lâmp, could It work?
Would it be possible to get actual build plans for this?
Hello sir
What is distance between led and condenser lens??
Great Video...But you whistle too much 😂😂
Very nice 👌👍👍
What is the name of square magnifing glass
Could you explain in detail how to get the LCD panel from a phone/tablet?
Andandos I normally use a hairdryer to melt the glue inside the device, take the front glass panel off, then the screen should just come off.
A Dead Meme
Nice thx. I tried it with an old galaxy s2 but then I realised that the device has an amoled display... Fail :)
If I apply this concept but I choose 5.5" LCD screen, can I choose XML T6 lamp, to bright the LCD screen ? (I am french)
Which wifi module you use to make the projector
Hi. At 2.42 i can see your screen has a reflective silver layer, do you remove it or you keep it on the lcd? Does this not hinder the light intensity? Thanks
The second one is 300-330, and the first one? What are the parameters of these fresnel? Please tell me
Cool.
A lot of old technology that used high powered light bulbs can be replaced with modern leds.
The old style bulbs threw out an enormous amount of heat.
Anyone wanting to try this would get a lot of the parts from an old slide projector.
The projection lens he uses is a Russian Industar.
Do you have any other socials to contact you? I have a question regarding this projector. Thank you!
nice diy :)
please post the final result and more detail if you can !
The only thing that i cannot find online cheap is the big lens 300mm..
Not necessarily use a 300mm lens, find the calculator on the Internet for calculating the projector's optics
Wer you bought 300mm lens???
where did you connect Nexus's screen ? how is it working ?
How much would you charge to build one of these and ship to the UK?
Hi can you give out the detailed dimension of body parts pieces.
Awesome way to teach every detail of every single part nice project..
Wow. Very simple method.
bijoy george simple my ass
Great 👍🏼 video
wow very gud project.
i actuly tried to make one but turns out its dimmer then a normal oled phone
so yeah not worth building
i use ten watts led
pls share a link for that front lens
this is very cool video i like it
why does it need the cooler.
can the project be smaller.
Really good work
I just wonder if you have offset the cost of just purchasing a projector. I have several and most were under $100 , and only one was about $150.
What we call the device used to automate the keystone correction fresnel lens
When he said "hi" he sounded like the joker played by Heath Ledger.
it looks like this projector has better picture than projectors you can actually buy and it has manual iris aperture and other worthy features, many of (especialy Epson projectors) have really poor lens
