Love your video’s! They are so cool!
I have everything ready, just waiting on the 4K phone and LED to arrive. Very excited to get started!
Hi DIY Perks, Great Video! What would I need to do to make this an ultra short throw projector? I have a very small space and would like to put the projector at the base of the wall I'm projecting on... I already own a regular projector so would it be better to modify the one I currently own to be short throw?
Hellooo!!! Can you please make a video on how you can convert a PC hard drive into a portable HDD ???
Great timing, mate! I just came back to this video with the intention to rebuilding it and - tadaaaa - written guide available 👌😁
Really enjoyed this 28 minutes of something I'll never build
@Zenki X Lmaooo, underrated comment
I dropped a like on your comment more harder than this video
I'm actually thinking about making a 1440p projector. I've been thinking about something like this for a while now but I couldn't find a good and cheap screen. And the one he found is just perfect. Gotta love the effort he puts into his videos and projects.
lol 🤣
i really really love to build this, but i just dont have the materials and money..
Let's take a minute to appreciate how long it must have taken him to thread all the nuts and spacers through those rods
and some of them were self-locking so he had to use a wrench instead of the load and good fingers
@@ruimoura6234 clamp the rod into a drill and hold the nut...
@@Flowxing that´s how i would´ve done it, also its amazing how much time you can save with such a simple trick
it had to be nuts
@@Flowxing Don't forget that spinning the rod spins everything else attached to it. Once the rods were all tied together with that base piece you couldn't spin one of them without the next one spinning around to hit your arm.

He is paid for this. He is paid very well in fact. Probably over $ 20 000 for this video including viewership money and sponsorship.

@@calamariaxo the difference is that DIY Perks' projects are effectively useful in everyday life (they're not compulsory, but they can help quite a lot) and the result is pretty good-looking.

I can only recommend the "arching" LED-Lamp...made if for my desk, and it is such a pleasure to work under!
I've made several of his projects and use them very often! The main one has been his LED light panel project. I've made quite a few different lights and use them for film projects and just lighting up my workspace. :)
😂😂😂
This is what UA-cam needs! More quality instead of quantity!
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.
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!

@@DaliasVlogs34 it was fairly plausible that you were _just_ out of middle school 😜

Well you’re definitely not a grammar expert.
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.
To be honest this should be number one priority for every parent from day one. Making things together and learning new things in the process, developing that brain power, for kids evolving their brain in the right direction and for the adults keeping that brainjuice flowing. With it making those social bonds. Win-win for both parties. Instead of the modern day norm of the majority that where adults chase false dreams stressing out them selves and their children and their kids being neglected stuck on screens doing nothing watching who knows what and growing into lazy useless parasites.
damnit. i'm tearing up, u a good dad.
You're a freemason? Because of your yt-symbol?
This is also the type of thing I was thinking of for my kids and I - they're a bit young still, but I definitely want to get them into loving this kind of thing. Also - that's some solid fathering you're doing! Keep it going, I'm sure your daughter is benefiting from this beyond what she'd ever even realise.
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.
I really appreciate that you work all alone like recording, editing, building new things etc, hats off to you man ❤️
3:39 Don't act like that nut didn't take ten minutes of twisting to get to that point. Haha
Lol. I can just imagine spending an hour to bolt down 4 nuts and realising you forgot something that had to go in first

I read that perfectly on time
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.
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.
While I agree this would be more efficient thermally, clearly this design already works, because the upwards force of hot air is minimal compared to the large kinetic force of the fans. Also I believe the tower design proves much more convenient when it projects from the top-end, rather than the bottom.
I believe you may have slightly misunderstood, actually the fans draw air downwards through it, which cools everything respective of its position. Air is drawn through the heatsink last, and then expelled outwards through the bottom vents.
@@Savage-en1ms Exactly.
When Matt said "This is going to be a good one" at the start, I already trusted him
I trusted him when he introduced himself
I actually agree with you haha
When matt said "this" at the start, i already trusted him

@@theindianallrounders thank you! Take care and stay healthy! 🌈
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 love how every Project is timeless an unique, no matter how often I look at them
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.
agreed I'm one of the many average people would never built this but I find it fascinating how smart and creative this dude is an his attention to details is really amazing. I was thinking how much he would achieve if he worked at high level engineering like in NASA or MIT

Respect for making your design open source!
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!
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
the battery is just providing the phone with power at the required voltage and intensity that it needs to run. the voltage regulator board was used just so that he could change the power supply for something that doesn't "run out" of juice, such as the power outlet, allowing him to just plug it in. think of it as a transformer. i could be wrong though, research the topic for precise information
@MyBadStudios well i know ow you feel xd... after searching a bit though, you'll think of it as basic electricity (there's nothing basic about the board specifically) but it's pretty easy to understand how to set it up at least
wtf i love ur videos man!
Oh sheed! It's the scambaiter!
@MyBadStudios If you want to do something you need to invest time into it to learn. We wouldn't all be sitting on our lazy asses while watching free entertainment on our phones or computers if it weren't for all the people that did the research and invested their time into it.
In this day and age, you can learn everything needed for this project for free with the help of the Internet and youtube. 100% free I'll guarantee you.
If you're mentally not prepared to invest effort into something then the only reason you can't do it is you and your mindset.

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

@@sebastianjohansen2142 6-27V? You mean that as a range and than get a stable, say 12V? Use a buck boost converter. They're inexpensive but just watch out for your output current, you don't wanna burn them.
I went to do a diy projector in 2010 but never finished the project as it was about the time I had to move iirc. Still have the parts kicking around in storage somewhere; fresnel lenses, 13inch screen (can't remember if it was even 1080p - might have only been 720p back then), triplet lenses from overhead projectors, a massive 400W metal halide bulb and ballast. Had I completed it, compared to what Matt has built here it would have been double the size for a quarter of the resolution.
It's interesting seeing this done now with leds. I also remember the de facto diy designs back then sandwiched the display panel between the two fresnel lenses (rather than it positioned after the converging fresnel) and moved the final lens for focusing.

its really not that big of a deal. its just a bright light source, a few lenses, and a LCD display with the back reflector removed.

Matt: Hold my aluminium.
Also nuts a
And the ironic part is the diy one has better color and IMO has slightly better image quality.
@@dcfuksurmom yes i agree imo earlier had egg in it but they started using human meat recently
The answer is simple. 4k is related to the area of the mobile display. If you project it on a larger screen, you get the quality of DVD (succinctly speaking). This is done by calculations, in which you set the pixel density per unit, width, length and diagonal of the display or projected image. An expensive projector ensures that the specified image quality is maintained if the installation conditions are met. If the image from the projector seems to be worse, it is due to the image processing algorithm (compression, etc.). Within this, the projected image from the mobile phone may look better, which is not the rule. If someone wanted to project 4k, they would have to duplicate the surface of the mobile phone as a mosaic to the total size of the projected image. In this way, for example, HD or Full HD panels are joined to the walls as a mosaic, which will result in overall HD or Full HD quality. However, such an enlarged image encounters the problem of enlarging the original pixel to several pixels. Therefore, the larger the format, the larger the resolution must be. The situation is absolutely catastrophic in the field of virtual reality. The human eye recognizes a pixel at an angle of 1 minute. Sharp sight can handle 24 seconds. Virtual reality brings the image closer through the optics, instead of zooming out, and therefore is still unsatisfactory. Limits are reflected not only in the price.
Because they are not made from mobile phones?

I watched the whole video thinking, can I make it, no I can't make it, may be I can. 😂
This guy teaches me something I’ll probably never make
Mind-blowing project! Amazing job!!!
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.
Yep also did this with a 15inch LCD( this required a much much larger box) back in 2005 ish I miss those lumenlab forums so many good resources, I still have my metal halide bulb/ballast , giant fresnel lenses and projector lens. good job with this build alot more streamlined than they used to be.
We've done many of those in our diy-community back in the days. From ultracompact models to 17" monsters in all kinds of designs. :)
RIP, Dr. Yu
this man looks like he's perpetually happy
That's because he's always using his first DIY - a vibrating butt plug.
That's because he has over 2M viewers, and well deserved too.
That's because he's high AF. j/k LOL
I would too, with that kind of skill
That's because he's British
Matt is like the Bob Ross of Tech DIY projects 🤣
Seriously impressive though. He actually manages to improve on commercial designs!
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.
I just absolutely love how excited you get for all of these projects. It’s been amazing to watch this channel grow since the video I saw where you put your PC in another room and made an volume knob out of concrete. I’m so proud of you!
I remember those video too, haha. xD
I agree 100%. Seeing his genuine excitement and enthusiasm really brings up the enjoyment level. Part of the winning receipt in this case. I’m glad you commented on it. :)
Awesome project with a better than commercial result. My favorite video of yours so far. GG
That's an instant like button just for the pop up "Hello!" intro. Love it.
"...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
I too have an XZ Premium lying around, working perfectly but I don't use anymore. So I might just try this myself as well!
I also have an old 720p Epson projector, I wonder if I can reuse its lenses for this... hmmm...
Hey, @MoSs - I have an old Epson projector too (EH-TW420 from ~2008, I think), with a defect light source, that's too expensive to fix, since it's outdated. Please let me know if you figure out something regarding refurbing the lenses of yours!
@@MoSs. U cant. 720p sensor(projector screen) will be 4x smaller than ur phones screen. So lenses will be also too small for that.
I had Z5 premium and same problem, but I still like sony phones
Actually the panel on the Z5 Premium is better for this project because the dpi is over 800. However the XZ Premium panel has HDR color gamut support.
This is a most brutal DIY project that i ever seen.
We've done that years ago in Germany, before Projectors became cheap. (diy-community dot de for example). Tbh his projector is quiet simple and could be a lot more optimized...
watch these guys building underground houses. you can do it in your garden too.
@@dr.comfort1183 Actually my wife and I tried to, but it is quiet hard to get a permission for earthships in Germany. So we are now building a straw/clay/wood house instead. :)
No lens shift or any lens size adjustment available too. I know how to make it bright (90% better). But the lens option is A MUST. Edit: hmmm, I have some ideas now.
@@luckyqualmi i did one out of an overhead projector build i got out of some MAKE style magazine when projectors where expensive and not very bright
amazing stuff, most quality content on youtube! Every Projekt is an Designer-Pice!
What a great DIY project 🙂
I have made DIY projectors in the past, and this is the best design with the best howto presentation I've ever seen.
I know I'll never make this in a million years, still I couldn't skip a second of this 28 min video.
That's the magic & skills of DIY Perks♥️
You are a true genius Matt!
This is so cool! Thank you for making the video (and the projector)
