Really enjoyed this 28 minutes of something I'll never build

This man actually made a pdf step by step how to make your own projector at home, this man is the kind of man who makes the world go round, GOOD JOB WHOLEHEARTHEDLY, GOOD JOB. You should be paid for this.

Normally I watch these videos to be amazed, and move on with my life, cause how in hell could I do this aswell. The problem tho is, as a matter of fact I strangely have every. single. component. to rebuild this… And now I’m invested!

I love how this guy narrates everything as if we're actually gonna build it. Let's be honest, we're here for the great quality of satisfying contents.

Let's take a minute to appreciate how long it must have taken him to thread all the nuts and spacers through those rods

Bruh, imagine buying a 2,000 dollar projector just to flex how much better your home made one is

I would love an update on this project to see how well the screen took this kind of use long term (if the light intensity damages it or the fans are not cooling enough on sustained use, etc.) Thanks for the video!

I just got this video randomly recommended, and I am completely floored by the fantastic projects you are showing and actually guiding step by step on how to make. Instant love to your channel, I promise to binge everything and build at least one thing myself.

This is awesome. Not just the end result, but the whole process of building it. I love projects that teach lots of skills along the way.

I love the lack of hot glue and snotty soldering. I love this guys projects.

This dude has taught me more about engineering than my actual degree

I don't know if anyone has realized that this entire channel and all your efforts (working so ingeniously and openly sharing the details of your projects) represents one of the most valid actions to boycott wild capitalism, decrease the environmental impact, while maintaining a modern lifestyle, and, at least for personal opinion, a great step towards the true evolution of humanity. Many thanks from the bottom of my heart. Keep up the good work, peace.

Diy Perks is like the Bob Ross of DIY - He has a nice voice and makes beautiful projects in entertaining videos, but most of us probably won't try to actually make anything.

if this guy was my teacher in middle school i'd be a electronic expert by now

I really appreciate that you work all alone like recording, editing, building new things etc, hats off to you man ❤️

You rarely find channels with videos of great length worth watching the entirety. But this channel is so worth it.

I'm continually blown away by how professional everything you make on this channel is. How you manage to create so many different things and always make it look good, function beautifully, and ever quiet is always incredible.

I just want to take a moment to offer my sincerest thanks to Matt for his work. I share custody of my daughter and we've done a few of Matt's projects while she's with me, and doing so is one of the reasons we've grown closer. It's not easy being a single dad to a teenage girl, but the experiences we've shared while learning and creating something new has been a true source of joy for both of us. So, thank you Matt. I'm deeply appreciative.

The world needs more people like this guy imagine what he could do for the people with a budget thanks for the work 🎉🎉

I've never been in my entire life more fascinated by a video of how to build something, I've watched this so many times and each time I do im a little more impressed, I am a million miles behind you I creating things like this, but because of you Sir, there is no stopping me now, I was in the Royal Corps of Signals British army at the bottom of any tech, you have rekindled my ambition to to build things and hopefully one day instruct others to do so.❤

This is what KZfaq needs! More quality instead of quantity!

25:19 "Contrast and colours are absoloutely on point." - Shows image of a blue orange

I miss how old youtube used to work. You colud find all kind of DIY and science projects on it. It's one of the reasons why I went to engineering college. Your projects reminded me of how the things used to be on YT.

This is the best DIY guides I've ever found in youtube. Reasons : it explain the theory, good for students. And also the creator has clearly inform the materials it needed. This is a very good DIY Tutorial. Thanks!!

I am interested in the bit where you replaced the battery with a small voltage regulator board - there is surprisingly little written about this kind of hack (or at least not that I could find) - I think 'hacking lithium powered devices to run off alternative sources' might be a worthy subject for a video of its own

I really wanted someone to explain the concepts of light and magnification in depth, thank you so much.... It was incredible as always

I wish I could communicate and talk as well as express my words as well as you can. The way you narrated this and made your audience as well as the people that brought all this together into one whole! My hat is off you all of you as well. real good. others saw this project I saw something else.

Yaptığın projeleri ev ortamında basit yapıyorsun ama ince detaylar, sağlamlık, malzeme kullanımı ve senin yeteneklerin ortaya fabrika kalitesinden daha mükemmel bir ürün çıkartıyor. Harikasın dostum Türkiye'den selam

3:39 Don't act like that nut didn't take ten minutes of twisting to get to that point. Haha

Matt feels like the holy fusion between Linus and the hacksmith with a lil bit extra

I love how every Project is timeless an unique, no matter how often I look at them

When I was a kid my dad made the exact kind of thing at home. I think it was 2006 when he made it. He used parts from old printers and computers. Unlike the one in this video, it was huge. All the components were enclosed in a 5ft-tall box he made from MDF and plastic, and it had wheels so you could move it around. It didn't have any heatsinks, but instead used fans stripped from computers to circulate all that heat. The craziest thing is, he designed all this in Microsoft Powerpoint 2003, and the most high tech tool he used was a power drill. As a kid, I enjoyed watching him work on it. The only problem was that my mom absolutely HATED it, so it's been sitting in a closet for the last 15 years.

I'm going to try building this! Edit: For sale: An aluminium tower with a melted phone in the middle. $60 o.n.o. Collection only.

"...and now it's...complete." *gets chills*

Some modifications include ditching the phone completley and using the control board with ChromeCast, or Apple TV to utilize ScreenCast, or AirPlay. Worth noting that you need some HDMI ports if you want to connect your laptop to the projector. Also worth noting that you need some way to make like a standby mode by wiring some relays to the LED driver and a momentary power switch. And if you want a control over smartphone you can make Arduino setup with the WiFi shield.

This guy is a freaking genius! How does he do that?😮

When Matt said "This is going to be a good one" at the start, I already trusted him

00:12 I thought he was going to say,: IT’S FOR free.

When you started talking about focusing, I got flashbacks to my time in high school photography, where I used an enlarger (my second favorite part of film photography).

I love the concept and your ability to just start doing. I think you've come up with a relatively easy, and fundamentally sound design. I do have one critique on the design aspect though. And that is the build orientation. You state that the orientation is optimized for it's footprint, and I like that but from a heat and cooling standpoint it's upsidedown. Horizontal projectors have their main heat source expelling heat away from all other components. Where this build has the heat rising to the LCD which is sensitive to heat and will reduce the hours of elongated use. If you where to flip the build the only modifications needed would be to flip the screen orientation. But you would be expelling heat much better, this along with fans directly actively cooling the LCD panel would allow you to get away with a much brighter light source. I'm curious of your thoughts. I would also be interested in your take on using a old classroom overhead projector as a starting point since you obviously have an ingenious ability to repurpose old tech.

it is very rare for a very smart person to deliver his knowledge perfectly to other people especially to those average ones who just enjoy watching DIY videos.

22:09 "the projector is complete" - it was the most soothing human words I heard today

Respect for making your design open source!

How tf we're you not recommended sooner? I watch Michael Reeves, William Osman, Smarter Everyday, and others like. You are exactly the style of channel I've always wanted. Ty so much

Good to see Theon Greyjoy find some motivation in life after what he went through in Westeros. Inspirational !!!

You've given me everything I need to overclock this project into a liquid-cooled, 8K, 5000 lumen monstrosity.

You're really good teacher at all. Appreciate and clap for your contributions for our mental growth in technology. Love for your all excellent projects. I'll be glad to be your student. ❤️

these projects are simply incredible

I just completed building the ultimate smartphone projector today which was uploaded by you earlier. I am so thrilled to see this video on this same day

I really, really appreciate the feel of demystification of technology this channel provides me.

You know, I really like the channel but I think it's the first time that I actually want to make the project myself. Really good stuff.

The work put in to these videos/projects in bonkers. Well done!

Can we take a moment to appreciate the amount of work and effort that goes through into these projects

25:20 "colors are absolutely on point too" Me seeing the blue orange: Whot?

Thank you so much, that is remarkable. The Agfa Repromaster lens uses is a process lens from a printers repro camera it will have coverage at least up to A3 and probably more!

I love the projector without the shell! Really want to do this now

Do have a feel for how many people try and do these projects themselves. I'm always like, I'm missing every tool, the space, all materials, skills to use the tools, 200 man hours, and more money than I care to lose if something goes wrong.

You are single handedly more interesting than the entire "How It's Made" franchise... Good for you

Stumbled upon this video while choosing a portable projector that i could use while camping. Quite epic, instant subscribe!

Feels like I’m back in Science Class …I Love it…Great Work! I love learning stuff like this… good stuff 👍

I only saw this video of you. I saw the entire video as a child playing with a new toy. I have no words. Amazing video. Amazing edition. Amazing project. Amazing explanation. You just gave us a free gold mine. I finished the video and subscribed without hesitation. If I didn't say it already, Amazing.

Give it time, there will be a 'Going to the Moon on a budget' video soon

You are a genius and your projects are just mind blowing

Like around 16-18 yrs ago, we used to do this with a huge metal halide bulb with its gigantic 10+ lbs transformer, a stripped 15" LCD monitor, a silver bowl-kitchen ware reflector (I forgot the name) and the lens spec'ed and designed by Brainchild. I wonder what happened to Brainchild's Lumenlab but I used to be one of those kids who made DIY projector. BTW, you can do lens shifting by tilting the Fresnel lens. I had this feature on my wooden projector that I used for 3+ yrs. Good times.

4:06 A light source with a spectral peak for each additive primary color would heat the LCD panel less or allow for a much higher saturation. The primary hues of the sRGB color space correspond to wavelengths of about 610 nm, 550 nm, and 465 nm. A CRI is a metric of similarity of a spectrum to black body radiation. If the color filter for each subpixel transmits only a narrow band of light, then any wavelengths outside of those bands will always be absorbed. If each color filter transmits a wide band of light and the source of light has a high CRI, then the colors will appear desaturated.

This guy is the true definition of an engineer

I love that he tells use what to do and how to do it like imma be making a projector at home

This is brilliant what this guy does! Kudos to what you do!

I start to sound like a broken record, but you really outdid yourself with this majestic project Matt!

Will definitely try this. However, I’ll get my local machine shop to laser cut the panels. Should be a pretty straight forward assembly process there after 👍🏻

This is such a fantastic video. The project is great, you give all the relevant info and more, and the video itself is shot so so so nicely. Plus your voice is pleasant, which is a bonus! Thank you for sharing this with the community!

Whatever this inventive man's mind settles on ,you can bet he is all in. Thank you, Matt, for generating the subscriptions, likes, and comments that show your impact on others.

By the end of this project I would be burnt, electrocuted and blind.

I don't think I have unlocked enough XP to be on this level, going back to older DIY projects.

priceless knowledge shared here, its amazing the willing of sharing which much people dont do. much respect

Best informative videos on KZfaq my projector mirror glass is broken and I'm using normal mirror but normal mirror make ghost image then I was facing big problem and my projector is not repair I'm searching in KZfaq and this video is really helpful for me I'm change the normal mirror glass to reflective glass and my problem is fixed thanks @DIY Perks

For those interested if utilizing the $60 2k display shown at 12:03 and the cheaper led bulb in the description, the total build cost comes to around $280 plus tax. This price also goes up because you need an hdmi audio extractor to make up for the lack of audio out on these display boards(roughly $25 on amazon).

This brings back the memory of building a LCD projector with metal halide lamp, striped monitor lcd panel, lens from overhead projector, and countless hours. Fun time. EDIT - Just occurred to me that it was around the time of SARS. I was a frequent visitor / contributor at the diyaudio.com projector builder forum. Among us, one was working in the largest hospital in Guangzhou. A good 3~4 months before any news report, he told us the grave situation caused by an unknown pneumonia, and how a number of his colleagues falled to the illness. We were probably among the first group knew about it in USA. Dr. Yu, hope you are all well.

Love your stuff. Glad to see you come so far over the years. From one geek to another. Congrats. 🤣😎

This guy is on another level ,absolutely a masterclass every video.

I have made DIY projectors in the past, and this is the best design with the best howto presentation I've ever seen.

Yesssss 16:54 the digitalrev tv soundtrack comes on when he talks about camera lenses!

This man is an absolute genius and deserves all the accolades

Who else sits here and watches these thinking we will build it, just to end up pricing them out on amazon😂 and ultimately not buying anything and forgetting about it

If I get stranded on a desert island, I want this guy with me.

I admire people who are whatching this cause they're actually gonna build it

I genuinely might want to build this, i dont have any experience but you made it so understandable

Thank you very much for being a great inspiration to people all over the world 👏🏼 God bless you friend 👏🏼👏🏼

"...Sony released a 4k phone..." I have an XZ Premium so which is overheating because of the battery... you just gave me an idea what to do with it :O

This is an awesome awesome build, so I hate to rain on this, but I own a Z5 Premium (and honestly this is the best 'graveyard job you can give that useless brick) and I feel I should clarify a few things: 1. ) The screen of the Z5 P is NOT a full 4k screen (which would be 4096 × 2160), but UHD (which is 3840×2160). Nitpicking? Yes, definitely. But all the ultra expensive 4k projectors, actually DO run on full UCI 4k. Projectors with a "normal" smaller UHD, are much much less expensive - but again, this project, for the price it'll cost, is tons cheaper. Also, obviously the aspect ratio will be off a bit. Dunno how the video app will handle this. Which brings us to the next, very important, point: 2.) To make sure people don't fall for the same misinformation from Sony that I fell for when I bought my phone, please be aware that the phone only displays it's full "4k" in two ways: Using the official Sony photo app and the official Sony video app. Install a different app for either one? No 4k. It won't even show you the option in YT's resolution settings. You'll only get what the rest of the Android system will show you: The sharpest interpolated 1080p picture that you have ever seen on a phone - which is impressive, but not what people who'd build this, would be after. So again, if you think you can use this projector to watch 4k KZfaq, you are mistaken. It IS apparently possible, to switch basic resolution with a few settings in Android, but we're talking about root access here. That would give you 4k everywhere, even on the home screen. This wasn't done in stock models, because as any owner of that phone can tell you, the screen already eats your battery alive at 1080p. In this set up however, battery power is no issue at all, so go for it and you'll be able to watch 4k KZfaq as well. I'm really considering building this....

Matt is like the Bob Ross of Tech DIY projects 🤣 Seriously impressive though. He actually manages to improve on commercial designs!

Mind-blowing project! Amazing job!!!

This is a most brutal DIY project that i ever seen.

This guy in school: Other kids: "For today's show and tell, I made a face with macaroni" This guy: "I made a 4K projector with scraps"

I would love to see a follow up to this where you build one that can produce as bright a picture as the commercial version. With a 200w or 300w LED.

Incríveis 😍😍😍😍 realmente vc está de parabéns 👏👏👏👏eu aceito de presente este lindo projeto que vc fez 😅😁

Me: Why are 4K projectors so expensive? Matt: Hold my aluminium.

this man looks like he's perpetually happy

A key concept here is Etendue. Light with a certain amount of Etendue has a limit to how small of an opening it can be focussed through, no matter how many lenses or mirrors you use. You can only sharpen it by discarding light from the light source. You need a low etendue high power light source for a good projector.
