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?
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.
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.
@@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.
Just cheked my investment portfolio on Chase. By the time this video finished, I had made enough money with my war stocks to buy a JVC 8K projector -- lock, stock, and barrell.
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.
He's at 95% imo. Everything looks great and does the job tremendiously fine. But I always feel like theres a small 5% overhead to take his projects to OEM standards.
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.
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.
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!
@@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.
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.
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. :)
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!
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
jholotan best ya, idk what middle school you went to but none near me went this into depth on anything. Dudes thanking the man for the opportunity to learn and you have to be a snob about it? Yikes.
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 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 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
@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 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
Are you the person who posted about making a DIY projector in Android community fb group a lot time ago. Because I just recalled one very-well detailed post in that group about DIY ing a projector , when I saw this . Is that you bro ?. Anyway , I hope you'll upload some videos about your build bro .
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.
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.
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.
Lol I made the hemispherical light panels a while back and it cost me a little over $400. Still don't have the right acryilic size as he never said. I think 1/32 will be the magic size, but haven't got around to buying it yet.
Rufurbished my laptop camera and fixed headphoned thx to him. Cool builds but i’m not that big of an audio enthusiast or silence enjoyer so his projects are over the top for me. I enjoy building shed’s and houses and such. Still-he really inspired me to do more electronic stuff. Still havent figured out how to charge a battery from 6-27 V of vindmill DC but the more I wach the smarter I get lol.
@@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.
I'm going to watch this, think about it for a while and then do something else. Sometime in the far distant future I will imagine I actually made this. Memory is funny like that.
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 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. :)
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.
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!
Holy cow that build is legit! Everything from the vinyl wrapped aluminum panels, to the cleverly adjustable focus rig, to the custom-milled threaded inserts is totally professional in every detail. If I had come up with this, it would have been gobbed together with epoxy and zip ties. It would be wobbly and frustrating. Yours is a triumph! A very good build with lots of helpful details. Thank you!

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 👍🏻
Yeah, the whole time I was thinking "wow, this project seems a lot more attainable than I was expecting, especially because I can just cnc all the parts, then it's just assembly." I definitely want to build it as well once i have some spare dollars.
I could imagine this approx £500 or $, could be more or less. It's just a guess. I have no idea if you were to buy a 4k LCD instead of Sony to control everything.
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.
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...
@@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. :)
I did something similar many years ago with a 720p lcd TV, a vapor bulb, a couple of fresnel lenses and an antique cinema projector lens. Yours is engineered much more nicely, and the LED source (which weren't available when I built mine) is much easier to deal with than the vapor bulb. It's much easier to get a great picture with the smaller LCD panel as well. Great work!
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.
They're just suggesting using an RGB LED that has red, green, and blue LEDs within the LED package that match the colour of the RGB subpixels on the LCD, instead of a white LED. By using a full-spectrum white light a lot of that light is blocked by the LCD panel since it can only allow red, green, and blue through it - so all the yellow, orange, violet, etc. that make up the white light are blocked (absorbed) and therefore wasted, and just end up heating up the LCD panel more. By matching the LED colours to the LCD colours one could use a brighter light since it would be more thermally efficient. This will present more engineering challenges though. RGB LEDs have three separate LEDs in them, one for each colour, so it may be impossible to focus all three to a single point - you would get three points at prime focus. Therefore a better option might be three separate LEDs, one for each colour, and use a set of mirrors and a dichroic prism to combine them to a single point. You'll find those prisms inside many projectors, which also contain a set of mirrors, and usually separate LCDs for each colour. See here: essentialpicks.com/wp-content/uploads/working-of-a-3LCD-projector.png
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.❤
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).
I love how each part was split into a segment, like a chapter of a book. Could you please add timings to the video description so that youtube recognised this and adds it to the timeline of the video?
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!!
"In this video we will be adding a so called "flux capacitor" to the space ship we built last time so we can achieve faster than light travel. It's actually surprisingly simple"
I actually remember something similar from school about 20 years ago, where there was an LCD panel (which I assume would've been 640x480 at the time) and it just went over a 90s OHP!
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 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!
Though I never got around to making one myself, I was a lurker on lumenlab back when it was a thing. This is as impressive as anything the community ever did there. One thing I do remember members of the community talking about were "heat mirrors" (Transparent material that reflects heat, but not light) vs "cold mirrors" (Mirrors that reflect light as normal, but allow heat to pass through) for controlling both the flow of light and the heat of the unit. This might be useful if you place a heat mirror in front of the led, especially if one were to go with a projector.
When I was like 6 years old, I cut out the bottom of a milk jug, placed a bright flashlight inside, and attempted to use it as a projector to cast film negatives onto the wall. I think my version beats yours for cost :)
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.
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.
Good project. You've got everything right expect the fact that the Z5 premium runs everything at 1080p with exceptions to certain sony apps to save battery and reduce heat. You can improve the image sharpness greatly by flashing a custom rom and a kernel that supports always 4K mode. Mind that the ability to watch 4K stuff doesn't mean the screen itself is operating at 4K.
@@basantathapa62 but things like Amazon Prime and Netflix would only work in 1080p, unless you don't use the phone and use a hdmi control board (which supports HDCP) and connect a smart stick to it.
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
I made one of these some years ago (not 4k) by taking an old 3M retroprojector and replacing the fresnel lens with a laptop screen and then adding another fresnel lens inside the machine before the bulb (note, i replaced the highly incandescent bulb with an LED projector grade one. I burnt the first LCD). It still works and is quite useful. Plus, it costed me only the new lens and the cost of the screen controller, which all in all was about one hundo. If you have one, it's worth it as it can then be refit inside the original case of the 3M which is actually decently small for what it is.
I cannot believe when some people disliked his videos. People needs knowledge and this guy is giving it all for us. Thank you DIY Perks for sharing this wonderful knowledge and ideas. Thumbs up for that.
its not like that lol. this video hurts the lots of companies system espesialy economically. those are definitely ppl that works on a certain companies
@@dimnyan seriously? :D You consider this setup as competition for retail projectors? Well if it would be in that case it meas those companies trying to sell us crap (which on many instances they're really doing e.g. many home appliance are same HW same capabilities and illusion of different product is made only but inactivating some part and price tag)! People are soo lazy these days... You better should look at it as inspiration. This project definitely teach you something and can spark curiosity and passion which might lead to new invention or company setup.
For a home build project, y'gotta admit that this is pretty damn awesome! Thanks again to Matt for his creativity & expertise. You may want to paint over the internal surfaces with something like Black 2.0. The darker that you can get them, the better - as then there'll be less ambient light to grey out the blacks in your image & lower the contrast.
At least not like that. Still more then enough left. Those overhead lenses will start a fire literally in seconds. I used welding googles just to look at the focused sunbeam.
@@koksem Watercooling will allow it to be at the same temperature with less fan speed, at least for a while. Bigger rad and more fans and you can lower the speed even more which results in less noice
@@lauri9061 but is it really worth spending money for watercooling setup for a little less noise while you can use quiet fans and add some kind of sound proof material on walls next to fans ? and also it may not even be a problem bcs when watching movie you also want to use good audio which will probably cover sound of fans.
@@koksem That's the great thing about DIY, everyone can build it in a way that works best for them. For some people water cooling simply to lower fan noise is a worthy venture, for others they might want to incorporate a media PC in the projector. For example, after watching the "reusing old laptops" video and this video I'm considering building a projector with a laptop's internals (instead of an android phone like in the video) making it a whole home media / gaming PC and projector all-in-one, with water cooling it as it's pretty beefy for a laptop and will put out a lot of heat inside the projector. This will also provide a small boost to performance as older gaming laptops thermal throttle a lot. It's my old gaming laptop that is fully functional internally (except for the battery) but the entire case is f***ed beyond repair (rough moves, nieces and nephews messing with it, etc, it has had a rough life lol) but it still has an i7-6700 and a GTX 970m so it needs decent cooling. I have a bunch of old smartphones that I can use for a projector screen. Water cooling is easier and cheaper than you may think. It's also a great DIY activity as you can get pretty creative (like using a cheap/used water pump from a fish tank for example) and don't care about visuals (which you shouldn't in this use case). The hardest part in my personal scenario is figuring out the mounting for the waterblock(s) for my laptop's cpu/gpu and cooling the VRMs. I've built and repaired a few PCs over the years so I'm comfortable doing this, but others may not be. TL;DR - The cool thing about DIY is everyone can customize projects to fit their own supplies and demands. The only limits are your imagination and your supplies... and maybe your patience lmao.
This is amazing! I will file this quickly under "keep dreaming you will never make this on your own" however lol. But I must say you pushing the mold is what makes your channel so appealing!
No, there are much more from a commercial projector like throw ratio ,type of inputs , size of a project image, lens shifting/tilting and most of all the refresh rate and input lag.
Also, probably also staff of projector companies also hate this. If they can't have a high enough profit margin, some staff will need to be laid off or outsourced.
While I do understand why you went vertical with this project, and the cooling system you designed certainly looks capable enough, a horizontal layout would make cooling much more efficient. Heat rises, after all, and in your vertical layout all that heat will be working against the cooling systems air flow. In a horizontal layout one could make that rising heat work with the cooling systems airflow, increasing efficiency thus making for quieter fans and an overall cooler build.
No kidding. I was legit just looking for a projector yesterday, and was pretty shocked… the prices for good ones seem to be around $2,000, with nicer home theater models reaching nearly $17,000. (No joke: www.amazon.com/dp/B07HY8HTKR/) Pretty obscene. But I just don’t have the resources to do a build like this, let alone experience.
@@jSyndeoMusic that does actually make this project more appealing. Maybe I could do it if spending an hour or two each weekend.... slowly chipping away. At the end tho everyone would have 8k :S lol

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!

Many thanks from the bottom of my heart. Keep up the good work, peace.
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.

Lol I made the hemispherical light panels a while back and it cost me a little over $400. Still don't have the right acryilic size as he never said. I think 1/32 will be the magic size, but haven't got around to buying it yet.
i haven't made anything but the el wire from one of his pc builds was cool so I bought some of that

Still havent figured out how to charge a battery from 6-27 V of vindmill DC but the more I wach the smarter I get lol.
@@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.

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. :)
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.

I could imagine this approx £500 or $, could be more or less. It's just a guess.
I have no idea if you were to buy a 4k LCD instead of Sony to control everything.
Can't you just 3d print it?
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.
This is a most brutal DIY project that i ever seen.

@@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
@Fernando Martinez how is it possible to make it brighter? And what lens is the best option? Would projector lenses work?
I did something similar many years ago with a 720p lcd TV, a vapor bulb, a couple of fresnel lenses and an antique cinema projector lens. Yours is engineered much more nicely, and the LED source (which weren't available when I built mine) is much easier to deal with than the vapor bulb. It's much easier to get a great picture with the smaller LCD panel as well. Great work!
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.
Sorry, I dont speak successful member of society
what does that mean for the build here? a different LED? color filters after the LED and before the lens?
.
They're just suggesting using an RGB LED that has red, green, and blue LEDs within the LED package that match the colour of the RGB subpixels on the LCD, instead of a white LED. By using a full-spectrum white light a lot of that light is blocked by the LCD panel since it can only allow red, green, and blue through it - so all the yellow, orange, violet, etc. that make up the white light are blocked (absorbed) and therefore wasted, and just end up heating up the LCD panel more. By matching the LED colours to the LCD colours one could use a brighter light since it would be more thermally efficient.
This will present more engineering challenges though. RGB LEDs have three separate LEDs in them, one for each colour, so it may be impossible to focus all three to a single point - you would get three points at prime focus. Therefore a better option might be three separate LEDs, one for each colour, and use a set of mirrors and a dichroic prism to combine them to a single point. You'll find those prisms inside many projectors, which also contain a set of mirrors, and usually separate LCDs for each colour.

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).
Did you like the quality or would you recommend a 4k screen? Also, how does the cheaper LED compare?

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.
Though I never got around to making one myself, I was a lurker on lumenlab back when it was a thing. This is as impressive as anything the community ever did there. One thing I do remember members of the community talking about were "heat mirrors" (Transparent material that reflects heat, but not light) vs "cold mirrors" (Mirrors that reflect light as normal, but allow heat to pass through) for controlling both the flow of light and the heat of the unit. This might be useful if you place a heat mirror in front of the led, especially if one were to go with a projector.

Good project. You've got everything right expect the fact that the Z5 premium runs everything at 1080p with exceptions to certain sony apps to save battery and reduce heat. You can improve the image sharpness greatly by flashing a custom rom and a kernel that supports always 4K mode. Mind that the ability to watch 4K stuff doesn't mean the screen itself is operating at 4K.
Certain apps means photo and video. This is exactly what this projector is for, isn't it?

One of the BEST DIY PROJECTS I'VE EVER SEEN
I made one of these some years ago (not 4k) by taking an old 3M retroprojector and replacing the fresnel lens with a laptop screen and then adding another fresnel lens inside the machine before the bulb (note, i replaced the highly incandescent bulb with an LED projector grade one. I burnt the first LCD). It still works and is quite useful. Plus, it costed me only the new lens and the cost of the screen controller, which all in all was about one hundo. If you have one, it's worth it as it can then be refit inside the original case of the 3M which is actually decently small for what it is.

are u an expert now?
this is amazing, i just dont have the time or patience for a build like this

we haven't time. Video 28min
Most of the world is currently at home in lockdown and you don't have time?
“using a 300w LED will mean louder fans”
someone will probably watercool it at that point
watercooling also requires fans, so it's actually not gonna be much more quiet but will cost more and will require a lot more space
@@koksem Watercooling will allow it to be at the same temperature with less fan speed, at least for a while. Bigger rad and more fans and you can lower the speed even more which results in less noice
@@lauri9061 but is it really worth spending money for watercooling setup for a little less noise while you can use quiet fans and add some kind of sound proof material on walls next to fans ?
and also it may not even be a problem bcs when watching movie you also want to use good audio which will probably cover sound of fans.
He already watercooled it in another project: ua-cam.com/video/6bqBsHSwPgw/v-deo.html
@@koksem That's the great thing about DIY, everyone can build it in a way that works best for them. For some people water cooling simply to lower fan noise is a worthy venture, for others they might want to incorporate a media PC in the projector.
For example, after watching the "reusing old laptops" video and this video I'm considering building a projector with a laptop's internals (instead of an android phone like in the video) making it a whole home media / gaming PC and projector all-in-one, with water cooling it as it's pretty beefy for a laptop and will put out a lot of heat inside the projector. This will also provide a small boost to performance as older gaming laptops thermal throttle a lot.
It's my old gaming laptop that is fully functional internally (except for the battery) but the entire case is f***ed beyond repair (rough moves, nieces and nephews messing with it, etc, it has had a rough life lol) but it still has an i7-6700 and a GTX 970m so it needs decent cooling. I have a bunch of old smartphones that I can use for a projector screen.
Water cooling is easier and cheaper than you may think. It's also a great DIY activity as you can get pretty creative (like using a cheap/used water pump from a fish tank for example) and don't care about visuals (which you shouldn't in this use case). The hardest part in my personal scenario is figuring out the mounting for the waterblock(s) for my laptop's cpu/gpu and cooling the VRMs. I've built and repaired a few PCs over the years so I'm comfortable doing this, but others may not be.
TL;DR - The cool thing about DIY is everyone can customize projects to fit their own supplies and demands. The only limits are your imagination and your supplies... and maybe your patience lmao.
This is amazing! I will file this quickly under "keep dreaming you will never make this on your own" however lol.
But I must say you pushing the mold is what makes your channel so appealing!
This man is an absolute genius and deserves all the accolades
Remember you emailing me about this 2 years ago! Must have took some serious R&D on your part. Great project matt!
Next on DIY Perks: "Building a Fusion Plasma Reactor on a budget" - ( THIS COMMENT WAS BANNED BY THE CREATOR )
Your comment is probably suppose to be funny,but the a 12yr old kid actually Built his own Mini-Nuclear Reactor in his Bedroom.
@@stevencaskey9440 isn't it in his shed ?
@@stevencaskey9440 are you talking about that 16yo cub scout or the fictional sheldon cooper?
Matt's ultimate DIY perk project must be a Tesla 3-staged Rocket on a budget.
@@DD-bv9jl Please don't compare that show to real science ever again
Projector companies are disliking this video.
No, there are much more from a commercial projector like throw ratio ,type of inputs , size of a project image, lens shifting/tilting and most of all the refresh rate and input lag.
No, this one is took big
@@FalleNoah which is worth shit to make
They're not. The LCD for that projector costs as much as a cheap projector. For that money you can also buy better used projector.
Also, probably also staff of projector companies also hate this. If they can't have a high enough profit margin, some staff will need to be laid off or outsourced.
While I do understand why you went vertical with this project, and the cooling system you designed certainly looks capable enough, a horizontal layout would make cooling much more efficient. Heat rises, after all, and in your vertical layout all that heat will be working against the cooling systems air flow. In a horizontal layout one could make that rising heat work with the cooling systems airflow, increasing efficiency thus making for quieter fans and an overall cooler build.
If michael Reeves was wholesome instead of edgy
More like Michael Reeves is an edgy Matt.
And posh
@Spring bhahaha stopit
don't think michael reeves counts as edgy
nuts, sure, but edgy is more like what 13 year old boys on 4chan are
But Michael I hear you ask... How are you gonna make a 4K projector?
Start of video: yeah this is something I might make!
By the end: :S might skip this one...
Same💀💔
Same
I tried to make one when i was 14yo, and I failed miserably
It was really fun tho
No kidding. I was legit just looking for a projector yesterday, and was pretty shocked… the prices for good ones seem to be around $2,000, with nicer home theater models reaching nearly $17,000. (No joke: www.amazon.com/dp/B07HY8HTKR/)
Pretty obscene. But I just don’t have the resources to do a build like this, let alone experience.
@@jSyndeoMusic that does actually make this project more appealing. Maybe I could do it if spending an hour or two each weekend.... slowly chipping away. At the end tho everyone would have 8k :S lol
Hey when are you going to make a DIY Quantum computer?
Edit: Wow, nice thanks for the likes!
Lol
Out of aluminum, old computers, and a few leds no doubt.
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.
