  • PROJECTORS! Building DIY projectors have always been a very niche thing, but when I saw DIY Perks's video on building a true, NOT smartphone projector, I got really excited. This is a video I made to show what a somewhat amateur DIY-er can do. This was a real challenge to build, as it took FOUR months to build, and an additional month to edit it and piece it all together., so I hope you enjoy it.

    nice work! To increase light output I used a condenser lens in combination with a light collector made out of 4 mirrors. By this you can get bright corners and an overall increased light output. You can easily cut the mirrors with a glass cutter (plenty of videos on youtube on how to cut glas). For the LCD I recommend using an old smartphone as it is cheap and with android you can easily use youtube, netflix, etc. To controll the phone you can either use a bluetooth keybord and mouse or just connect another phone with teamviewer or a similar app. For the projection lens you can use diffent type of lenses. For me an projection lens of an Episcope worked great.

      For the LCD panel, I really wanted HDMI input for some reason, probably for the cool factor. Looking back on it, since these LCD panels with control boards only accept HDMI input from computers, I should’ve probably gotten a used LG G3 for about $60 or just the standalone screen (1440p) and used that. It would’ve shaved off some of the cost and also the need for a computer with the asterisk of needing a mouse and keyboard. Just out of curiosity, how much time and money did the light collector take to make?

    • @MultiNumb3r

      @@justabit9070 The collector is made out of a standard mirror from hardware store (around 10€) and a simple glas cutter (5-10€) is used. so its pretty cheap. Cutting glas/mirror needs some practice so I recommend to practice on an old glas or mirror.

    Hi @JustaBit I'm yet to start building mine (working out some changes I'd like to make for a ceiling-mounted projector, so no 45deg mirror, but will need to use lens-shift of -50% (actually done through lcd-panel shift to keep the led and lenses in a line), so a complete image is projected off-centre from the lens-line without key-stoning).
    One thing I picked up from Matt's build, was his cooling-system relies on negative pressure throughout the "tower", this means the side-panels must be airtight except the intakes at the top. And your build looks like it isn't airtight (I could see quite a bit of light leaking at 28:15)-> the heatsink-fans are drawing air from those gaps as well and thus pull less air along the lcd-panel

    • @justabit9070
      @justabit9070  Před 3 lety +2

      Hi, thanks for the comment. That’s an interesting idea, using I’m assuming a tilt-shift lens? You could also avoid the keystone effect by making the second fresnel lens “able to tilt” on the y axis which would allow you to be off center from the wall a bit. Also, I know I have a BUNCH of light leakage, and later I covered most of that with electrical tape and vinyl wrap (LOL).

    • @marcodebruin5370
      @marcodebruin5370 Před 3 lety +1

      @@justabit9070 Don't think I need a tilt-feature, as long as I can keep the planes (lcd & lenses) parallel it won't create keystone-effects. But will need to shift the lens with regards to the lcd. I'm figuring a large format lens with an image-circle large enough to capture the whole lcd-panel when its long-edge is positioned along the centerline of the image-circle (large-format targeting a 5x7" sensor will do, a 4x5" target is too small for a 5.5" diag lcd). No need for complicated lens-architecture, as I don't need to be able to adjust the positioning once the projector is ceiling-mounted at the right throwing-distance. I may need to look at wide angle lens though to make it a short-throw projector because I don't have too much room to position it far back (a ceiling-fan to deal with).
      So, I'm settling on finding a 5x7 large format wide angle lens with a focal length somewhere between 100 - 150mm and a fresnel-pair with compatible focal lengths. How hard can that be? LOL
      Other considerations I'm going through is the LED power - I'd like a reasonably bright image, so looking at possibly a 200W LED and significantly stronger cooling architecture. Here I found this product: www.knightoptical.com/stock/default/filters/heat-control-filters/hot-mirrors.html which may help protecting the lcd from any infrared coming from the LED (although that is very small compared to the visible light-output, a small percentage of a large number may still be an amount to worry about, further research needed.....)

  • @epicunicat20

    I notice both you and Matt used the 100w 6000LM LED, I currently use an LED projector with 2400LM output. What's the lumen output of your projector? After the LCD and lenses? Mine works okayish during midday with the sun out, I have blackout curtains in my living room but have generic white blinds in my dinning area which gives a lot of color washout on my screen. I'm hoping the 6000LM LED would fix a little bit of the color wash (I know it won't fix it completely), but hopefully it will be about twice as bright as my current projector setup.
    My other though was, if the 6000lm LED yall used doesn't put out the light I need it to, I was thinking about going to the 400W LED from YUJILEDs with a lumen output of 26,000LM. I know with this I will have to buy a far larger full frame lense but that's something I'm willing to deal with.

      The backlight of my LCD panel was easy to separate. However, if the back isn’t coming off easily, then use a hair dryer or heat gun on low to weaken the adhesive. After that, all you need to do is remove all the fresnel layers and diffusion layers until you reach the polarizing layer. Don’t remove that since then you won’t be able to get an image at all.

You could buy it, see if it works, and if it doesn’t, Amazon’s return policy is pretty good, or you could keep it for other devices. If it works though, your biggest problem would just be figuring out where to mount it inside the chassis inconspicuously.

      Hi you need to connect the input of the fans to the power supply because if you connect your fans(which may be 12v or 24v) to the voltage regulator it will fry your step down regulator if it is not rated for the voltage of the led(which might be around 30 or 50v depending on the type of led you are using) or if you connect the fans with the step down regulator to the step up regulator use a step up regulator which is rated for at least your led wattage+fans wattage and a step down regulator which is rated for your led voltage,I recommend you use the power supply because it is the easiest thing to do.

  • @jobson88
    @jobson88 Před 3 lety +1

    Cool, I'm building it too, but from the original video, I totally missed out on the step down (only had step ups). Where I could use some help is with the wiring and connecting multiple devices (led 36V, fans 12V and then lcd at 5 volt) on a single power supply (120W)- and the step up, step down converters (2x) in between. Anyone?

    • @justabit9070
      @justabit9070  Před 3 lety +2

      @jobson88 I can help with the wiring, but first off, I don't think that a 120-watt power supply is enough. I mean, if you add the power consumption of all the components, you're just brushing up against the 120-watt limit. This will greatly reduce the efficiency of your brick and will mean that the PSU will be drawing a lot more than 120 watts TO provide the demanded power. Furthermore, even my 150-watt power supply got SUPER hot under load so we can safely assume the same will happen with a lesser wattage 120-watt PSU which will reduce the lifespan of your brick. So you might want to get a 150-watt brick or higher making sure that the voltage isn't too high and the amperage is too low (you'll need about 7 amps depending on your situation).
      With that soliloquy out of the way (LOL😅), you should probably start off with testing the components and circuitry BEFORE mounting it inside the chassis. So you can do this by first soldering (or just temporarily sticking) thicker 16-gauge wire to the power socket. The other end of these wires will be the "points" at which you will connect the step-ups/step-downs. Then, I would twist together a 20 gauge wire to the "points" which will go the step-up that will power the LED. Solder or temporarily connect those wires to the step-up and then from there, solder wires to the LED and put the LED on the heatsink. After that, go through the process of powering the LED (lowering the voltage, gradually increasing it, and capping the amp-draw), and the main section has been powered! Next, you can solder or temporarily stick another pair of 20 gauge wires to the "points" which can be connected to a step-down board that's set to 12 volts. Connect the fans to the step-down board and your cooling system is powered! Lastly, connect another pair of wires to the "points" and connect those to a step-down board set to 5 volts (or maybe 12 volts depending on the driver board). On the other side of the step-down, connect a spliced Micro-USB cable and plug that into the driver board. Now your display has been powered! Then it's just a case of resoldering the joints but inside the chassis.
      Hope that helps!

      @@justabit9070Superb! Many many thanks. I'll draw a scheme and check back with you if I've understood correctly. My idea was that de the led draws a 100W, 2 fans 8 Watts and the screen about 2,5-5watts staying well within the limit op 120Watts. But the step/up step downs generate a little heat, so somthing is lost. Also, I'm also still considering powering the screen through usb (double hook-up to the laptop: hdmi + 1 usb, also protecting the screen). Anyway, your advice helps a lot, showing me I should make the "points' (power bridge I'd say :) and connect them al to it (and not in series or something).

    @mostafahabibi3842 Před 3 lety +1

    Amazing! I was looking for someone who made this build idea from Matt because I didn't want to pay for his pdf guide xd I have a couple of questions though:
    1) Regarding the fresnel lenses, do their focal lengths have any influence on the size of the projected screen? Let's say I want a 2 meter by 2 meter (yes, SI units are the best) projected screen on my wall, do I have to buy a different set of fresnel lenses than someone who wants a different projected screen size? Or does the projected screen size only depend on the size of the lcd screen?
    2) I was doing some research and I found the blog of some Korean guy who made like 3 or 4 projectors like this (maybe you also found this blog) . However, his build had way more steps and was far more complicated and expensive. He used what is called a condenser lens, which seemingly makes the light being uniformly emited over the screen. Is this the same thing as your second fresnel lens? Is there a difference between a condenser lens and a condenser fresnel lens (the condenser lens appears to be round I think while the condenser fresnel lens appears to be rectangular)? Do you recommend using a condenser lens to have more brightness?
    3) One of the things you did differently from Matt was the extra fan for the lcd panel. Is there a reason why he didn't mention it, since obviously it did cause some trouble for your lcd screen? Also regarding this particular fan, how do the blades of the fan have to rotate? Does the air have to go from the outside to the inside, through the panel, all the way down to were the other fans blow them out?
    4) What about the throwing distance of the projector? Is it possible to adjust the projected screen size without moving the projector (I live in a 3 meter by 3 meter room) ? Or does the focusing/pulley system provide for that (I have seen some diy projectors without a focusing system so what are the benefits of it) ?
    Sorry for the many questions, I am just so excited to build this and I don't want to fuck this up :D

    • @justabit9070
      @justabit9070  Před 3 lety +3

      Hello! The way I understand it, you can have many combinations of fresnel lenses. For example, a 90 mm focal length and 170 mm is a good pair(like in this build), and so is 120 and 185 provided that you have a projection lens with a focal length of about 200 mm. I honestly don’t have a very good understanding of optics, but there are some optimal combinations. One of the ways you can adjust the size of the projected image is to just move the projection lens up or down to bring it in focus or to use the focusing system. I moved the projection lens because that seemed to work better. As far as I’m aware, there is no way to adjust the throw in a convenient way but I haven’t experimented with moving the fresnel lenses around in my build. You CAN try putting your LCD panel in the middle of the fresnel lenses and see how that works out. And for a 2 meter image you’re probably gonna be 4 meters away from the wall.
      Regarding your second question, a condenser lens specifically is different from a fresnel lens, but I think sometimes they’re used interchangeably. In this case, a condenser lens could be placed on top of the LED since its a hemisphere. Honestly, this is one of the things I was planning on adding to it later on. It’s definitely worth a shot, but you might want to add more cooling for the LCD panel!
      Speaking of the LCD panel I’m not sure why Matt didn’t have any issues with his; maybe because phone screens are tougher than separate LCD panels? xD. Anyway, I had the fan blowing air in, and luckily it just goes with the air pressure if that makes sense. The negative air pressure from the fans on the heatsink would pull air in anyway, and this fan just helps with that.
      And finally, as I mentioned, I don’t know of a way of adjusting the throw, but you could try putting the LCD panel in between the fresnel lenses and messing around with the fresnel lenses. For example, you can add tilt control by making the second fresnel lens tiltable.
      Happy building!!!

      At about 3 meters away from the projection screen, in my case the projected image was about 3 meters diagonal. You can adjust this by moving the projection lens up and down. Also, you probably already know this, but keep in mind the larger you make your image by moving it back and adjusting the lenses, the less bright it’ll be because you’re spreading the light across a larger surface area. Hope that helps.

    Do you think it would be possible to make the structure out of wood and not aluminium? I was wondering if it would cause heat issues or others

    • @justabit9070
      @justabit9070  Před 3 lety +1

      I was actually considering moving the components into a less vertical wood enclosure, and the only thing to watch out for is wood particles going into the components (especially the LED). This wouldn’t be an issue if you didn’t need fans for the system, but unfortunately, you do, otherwise the LED and LCD panel will overheat. So yeah, using a wood that doesn’t rot and warp along with sealing it should be enough to keep it safe. Plastic is another viable alternative if wood just isn’t strong and durable enough.

    Hey. First of all you need to focus your light source because a LED chip has a ~170 degree beam angle and you waste a lot of light. Second you may to change the led type to a smaller emitting area like an ygc 200ww this has a 13x14mm emitting area. You will get a lot sharper picture ✌️ you may need a radial fan to cool the lcd with the new light source but you will get a lot more light output and sharper image quality.

    Hey dude, you r make my day )).
    after watching Perks video, I dreamed about building my first diy projector, but I haven't space area for my DIY works&project (.
    questions:
    1)does this project worst to make VS buying used fullhd 1080 fabric projector?
    (prices for average diy components
    vs used projector price used
    2) I have one great idea for replace compatible light source like led/xenon and etc from automotive or other headlighting components for decreasing cost of DIY .
    thank a lot for this work .
    Regards!

    • @justabit9070
      @justabit9070  Před 3 lety +2

      @Ricardo Tozzi thank you. This projector is definitely more expensive than even a new 1080p projector, and much more expensive than a used 1080p projector. Commercial projectors will be brighter and more compatible. However, if you have a lot of the tools and some of the parts, then it might come out to be cheaper. If you add things like a condenser lens, a brighter LED, and a proper TV Box LCD panel, you’ve got a pretty compelling DIY project. Only question is: “Is it worth the time?” For me it is because I learned a lot and had fun but maybe not for others.
      Modifying a commercial projector sounds interesting because you could swap in a more powerful LED with a better cooling system and condenser lens. Very cool stuff!

    • @kurjibhalsod3547
      @kurjibhalsod3547 Před 3 lety +1

      On your point 2, i also thinking about that, because I can get 6500k led with 9000 lumens if I choose led projection lamps made for cars. But here is catch, car use two led projector, and that 9000 lumens are if you use both LEDs, single led have only 4500 lumens. That's why I'm also confused if car projector lights can work in it or not.
      Plus point for using car led,
      (1)projector is you get ready to fit kit with heat sink and power controller. You only need to add fan as your projector is not moving like car, so need active cooling.
      (2) so cheap that you can get at half price with power controller then other diy cob LEDs. Just plug and play.

      I would say try using a regular case fan to see if that’ll work, and if it doesn’t, then maybe look at higher powered fans and more extravagant cooling solutions like maybe a transparent peltier element cooled by a transparent water block or something. I would also suggest other methods of capturing light with lower wattage LEDs like a concave mirror behind the LED and a condenser lens.

      @justabit9070  Před 2 lety +1

      I was thinking of a 300 watt COB in there but so far I haven’t because of all the extra power needed but also how much heat the LCD panel can take because it was already having issues with a 100 watt LED. I think the biggest issue is light leakage and wastage so a tighter design along with a condenser lens would go a long way for the projector.
