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.

[@hammerland4028]

Thanks, good idea

[@coldbloodedscientist6159]

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!

[@haminepali9301]

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

[@lazercloud2110]

HamiNepali also if your lucky, you can look on ebay and find them stripped down already.

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!

[@reedtan]

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.

[@dezastruos]

wood vs electricity vs heat! Gotta love the combination!

[@luisantoniomarrega1120]

Amigo, este é o melhor projeto de projetor que vi na internet até hoje. Parabéns! Rio RJ Brasil

[@3m_art001]

it is the most amazing thing that I ever seen in my life.

[@DiePixelspieler]

Cool, Dracula is building a Projector!

[@RogueSamd]

Lol😆😆😆

[@ilhemedu31]

because you can,t do one lake it?? bee a dracula and let see your works 😂😂😂

[@JeremyCook]

Great job. Having tried a projector with a single mirror and smartphone with marginal results, this is really incredible!

[@Evan2]

Wow, didn’t expect such a high quality result from that. Very well done.

[@gseeleyj]

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

[@jamesbryan7501]

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

[@elfo247]

Exactly!!

[@TDPlayz]

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!

[@brianboni4876]

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!

[@sleepy962007]

WOW I did not expect to see such quality of video come out of this thing... very nice!

[@lazercloud2110]

Kind of a pain, but in the end, this project was worth it. Thank you. You're awesome!

[@TercioTeles]

INCRÍVEL! adoro seu canal.

[@Balschoiw]

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.

[@thoriqramadhan7604]

Simply the best explanation I've ever seen about DIY Projector. Thx a lot... 👍

[@limatoshi5845]

WOW!! one of the best DIY projector tut.

[@MuhammadFaridulIslam]

Just one word to say, WOW!

[@techboxon]

Hey. You made it very useful. Congratulations

[@adityaravishankar]

Amazing work... Looking forward to the next video... I'm probably going to try to recreate this :)

[@gabrielmachado635]

Holy Molly! Nice work man! I'll do it any time soon!!!!

[@aomo5293]

Thank you, I need one for teaching !

[@glenn4349]

Perfect design!

[@oleurgast730]

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€

[@diegolozano2397]

i love your video, hugs from colombia.... thanx for the knowledge

[@jesselejarzar5114]

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.

[@zenoist2399]

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.

[@s3savage]

You are a design engineer... Good work 👍👌👌

[@subsaharankid1554]

As soon as i finished this video i subscribed, you are genius and i hope to learn more from u

[@arkano01]

well is really interesting to see a much better quality in this DIY project than many expensive good branded projectors out there.

[@varthdaver9940]

Waoooooo......Hermosa idea me encanto! Gracias por compartirlo! ; )

[@jankriz9775]

This is insane... Good job

[@RimWulf]

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

[@JayDAnderson]

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.

[@isackawala1988]

where can i get these lenses please?

[@leozendo3500]

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!

[@hammerland4028]

In fact, if you understand the theory, everything becomes simple

[@leventedavid7400]

Hello ! Nice work. :) I can see the use of a tablet LCD. Does the LCD turn on the input?

[@Ali-Britco]

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.

[@arunrewatkar735]

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

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
