+Deathmonkeyjaw Well but you might just simply buy what you need from ebay and not a actual projector and actually end up with a very cheap projector... Though to get a high quality picture out of it really needs a lot of calculations to know how big the box needs to be, screen size esolution, what magnifiers to use and the best distances between them and it would be convenient to also improve the focus system with something more adjustable... Im thinking that will be such an hassle that it is just better to buy a cheap led projector lol.
Thing is, there's quite a few projectors with busted imaging components and shit lamps. The filters, lenses and focussing mechanisms practically never fail (because they are just passive pieces of metal, glass and plastic) So broken projectors are really a great way to get components to build your own projector. I used components out of a really old VGA projector to make a HD Projector.
I built a projector some time ago, trust me your problem is that you also need a fresnell lens in front of the LCD. Also remember to put the fresnel lens on the correct orientation. If I remember correctly the side that have ripples should be facing the lcd. So the correct sequence is (LED) -- condenser-lens ----- [Fresnel} ---- [lcd] ---- {fresnel] ---- (objective). I hope this is useful
Is the first lens glued to the LED really necessary ? What's the point of converging light then diverge it with the Fresnel lens ? What you want is to illuminate the entire LCD screen, and pass all the light trough the last lens. For that I'd rather have built the projector as : LED -> Fresnel Lens -> LCD -> (Fresnel Lens) -> Polarizer+Lens. The second Fresnel lens should converge light to make sure that all the light pass trough the last lens. Anyway, good job it's a nice project ;)
+LightHack I think ist is. Because for projection you want to be the lightsource as small as possible. Otherwise you won't get a really sharp image. So I guess because of the first Lens, the Fresnel 'sees' just a narrow point of light. But anyway, I think that this kind of LED is not usable for a real good projector.
It's from the version I had, I disassembled it once to fix the Blu Ray drive took 5 hours no help from RUclips and worse disc was stuck.and yes it is a fat ps3 PSU
what i like about this channel is that all are creations of Scott and not all projects go well at the first time. Thank you for share your projects with us!
This reminds me when I was a kid my grandpa took a shoe box, a switch, a 9V battery and showed me how to solder up and connect a light bulb to a switch. simple I know. but that small project probably sparked my love of electronics.
+GreatScott! maybe like what to do with them and how safe they are and maybe also try snother batterys like life bat and try to do a bluetooth speaker witch can fit in your bag or something like that
What is the color temperature of the led? It's look like 4000K. (warm white) For projection it must be 6000K (cool white like the backlite of the lcd screen)
But he still puts a lot of time making the video. What matters is that no matter how "not good" the video is, he still has great motivation to teach others. 😉
Yea when I saw that flappy plastic lens I was also like.... I don't think that is going to work. But man!!! A shoebox led projector?? That's ffing amazing man. Nice work!!
Get a replacement screen for one of those 4K phones or tablets, and use that, you'll be set. Also, I have some improvement notes for it. 1: the magnifying glass was too small. To show the whole display, the display must be small enough for the magnifying glass to cover all of, or the magnifying glass must be larger to compensate. Also, the metal rim could be affecting the amount of light able to get in at the edges slightly, so the inside half of that could be cut out. 2: the light fission plate alone will never diffuse evenly. If you want more even diffusion, get some aluminum foil to line the walls behind the fission layer. Even better, get some small mirrors to seat in the floor and tape to the walls. 3:the magnifying glass shouldn't have been as far away as it was. With as much room as their was between it and the display, or esoecially in tuning, the display and the fission layer, the light from the fission layer could lose its evenness, especially if there are places ofr the light to bleed out of. Try it with a smaller display, a magnifying slab that is large enough for all four corners of the display to be within the bounds of the magnifying glass at the same time, and with aluminum trim or taped on mirror slabs before the fission pad. That will ensure that it works correctly and enjoyably.
Lol the sony logo a dead give away and having taken hundreds of them to bits .....ps3 psu ftw , I also love old xbox power bricks very cheap simple and quick way to get a load of 12v for way less than most other options.
edges of image looks blur because of depth of field ,you have to make aperture in front of lens by using a cardboad , narrower aperture causes lover ligt but shap image
at school our computer teacher used to put an lcd screen on an old overhead projector. it was a clear lcd screen especially for this purpose. it worked really well!
Yet another great video! Could you do something along the lines of SMD soldering? Specifically using hot air would be awesome (: .Keep up the good work, you've taught me so much!
Normaly when i see a diy projecter i always directly think: this is so stupid. But now even before watching i'm like you are going to make it so it is going to be awesome!
Hey, try remaking this same thing now. I'd like to see it. And use wood instead of cardboard and make it a permanent setup. Nice work with the cardboard projector.
The fresnel lens you used is equivalent to a concave lens that spreads the light out. You need a convex lens, like a fresnel book magnifier that you can find at dollar stores
this has gota be the sketchiest build ive seen from you. cardboard box? title it "how to build a house hold fire ignition system. I calmed a little when you noted it was a 30w led...i assumed 100w but still lol
That was a Nice try. In my Opinion the Shoe Box was not the best of places for a project like this. Why not try a Prototype Box instead? I really like your channel, and I've started my own with Electronic and Programming Projects.

Your tone is hilarious. Can't tell if you're excited for the project, or bored out of your skull. I have to assume you're having fun. It does look like an awesome project. I would love to see an update to this with attempts to improve.
Awesome, I once made a prototype with an overhead projector (modded to work with a 30 watt led) and an old laptop. It worked nicely, a bit big but hey. Sadly I messed up the fresnel lense when cutting it to size and after that I broke the ffc on the laptop screen, way to go me :-P
If I were to actually do this for a cool 1080p projector, do you have any tips? and how does the resolution on the wall work? because it seems that an 800 X 480 screen stretched out to say: 60 inches doesn't look very good, more like colorful legos! (PLEASE GIVE ME THE UPGRADED FRESNEL LENS VIDEO ;D) thanks!
Just use 2 same fresnel lense. One for front of display and other for back of display and increase the box lenght.And and and don't remove film from display. It will sure work coz I have made mine successful and it gives about 100inch projection. Thanks
The diameter of the projection lens does not have a bearing on the amount of the image being projected. If your setup did project the full image of the LCD panel, you could place against the lens an opaque material having a small hole and the full image would still be seen, but dimmer because of the reduced aperture (like an iris diaphragm.) Your small area of projection, covering only the central region, is due to the collimating lens at the LED being too small. It cannot fill the area of the larger LCD panel with light. You need a collimator of diameter at least as large as the LCD's diagonal dimension. Furthermore, you need to pay attention to the separation between the collimating lens and the LCD. An incorrect separation will contribute to vignetting, or a darkening of the outer part of the image.
This projector gets the job done pretty well. ruclips.net/user/postUgkxS9P8zTOcmQg-hH0QeUi3dspOLyYgQ6dH Bear in mind it's a mini projector but all things considered the picture quality is pretty good. The attached photo is of the projector projecting onto my white closet doors. I still have not messed with the settings but I can't wait for our first family movie night on a larger scale. If you have issues with volume not working with your firestick, go into volume settings and you will find your solution there.
PS3 power supply unit, a drill used on a cardboard box and more over a heat sink being used on a paper and finally a projector project could not project??😆😆
I don’t quite get the idea of these videos, could someone explain why would you wanna make a projector when World is filled with projectors and you can get a decent used machine with few hundred.... i mean these Arent free and if the Parts Are your time isn’t.
hey scott! i have an arduino uno and an idea, but no practical knowledge. would you be interested in making a tutorial for hacked washing machine? i would want to hook up an arduino to it and give me an sms message or some notification when it is done washing. my washer is 3 stories below me so it would be very convenient. i tried searching for some similiar projects but came up with nothing.
Way better idea is to use old overhead projector(like school ones) and old TFT monitor. Add active cooling and you got yourself a home theater with resolution that's not even available on the market!
make the case 3D printed next time and maybe give it an autofocus feature? (stepper motor moves lcd or lens with ballscrew and a distance sensor and math determine the position of the motor to focus)
Oh, so I have to have a spare projector, a spare high ampere power supply, a spare processor heat sink and a spare lcd to make a projector, sure, makes sense

@@rahimkvayath you could turn the screen around and flip it upside down
in video time 2:55 he get out an special lens from old projector. I think it was aspheric lens that correct the optical aberration.
Even though it didn't work out it's still a hell of a lot of work you did in a week and we learned from your experience

It was my dream project.. but even you are failed here (almost) ... That means I will definitely 😂😂
What is the color temperature of the led?
It's look like 4000K. (warm white)
For projection it must be 6000K (cool white like the backlite of the lcd screen)
It depends on your likings. Different color temperature can change the image output. So i guess its trial and error
Great Scott..😉 nice try but...Not that good as compared to ur other videos.. but again great try...
But he still puts a lot of time making the video. What matters is that no matter how "not good" the video is, he still has great motivation to teach others. 😉

Great video! This is very creative! This projector is much better than my one i made for smartphone. =)
Hey man, great material as always. Too bad those 7" screens are the same price as 22" used dell monitor :/
HDMI interfaces, graphics and, portability are what raises the price
rather just buy a 400 dollar Epson 3lcd projector so it actually works... if it evolves more and works better, maybe
i put a magnifying glass in front of my phone and called it a "projector"

What happens when I put LCD clock ..?

I've been looking into using a cell phone LCD for a projector. Have you found any way to connect a PC to a phone screen?
+Jakob Orkin 'just' make it that you can put your phone in it ;)
The power supply was probably salvaged from a PlayStation 3 as I disassembled one as well and it looks quite familiar.
I am dreaming with the tools u are using in your videos😢😱😢 even the pen 😉😂😂

nice. Maybe if you make the interior with white paint...
+Marcelo Franceschini I thought about that too
You could of done a better box.
I wonder if you kept the diffuser from the LCD on it, if that might help. Also lining the box with white paper or maybe foil to help with the light.
The thumbnail was mislead to what the video was actually about I thought it was one of thoughts phone projectors but it was way better
Very nice Just like a real projector
Hey etechguy i love your vids !!!!!!
You are doing youtube now?
The problem you have is called "Overscan"

+willian beck Ribeiro Sometimes enough is not enough
+willian beck Ribeiro Why should I use a nail if I have a drill right next to me?
Next time try using the laser burner! :D
The exact centre of the lens has to be perfectly aligned with the LCD screen and the LED or you'll still have the same issues

What if you remove the focus lens from the led? Then the light would get spreaded better, even before it hits the fresnel lens.
+Rcmodellbau_DE That is a defusing lens, not a focusing lens. Removing it would make some very bright spots.
how is the image without the lens on the LED?
I think it should be better / not so bright in the middle
+GreatScott why did you go for yellow LEDs instead of white LEDs? Would that make a difference on the video output?
hey scott! i have an arduino uno and an idea, but no practical knowledge. would you be interested in making a tutorial for hacked washing machine?

Maybe if you use a smaller LCD, one that'll fit the Fresnel lens, and cut the box to fit, you might get a better picture :D
True, But you might loose a bit of resolution. Correct me if I'm wrong
get a 600*800pixel uc40 led projector and use the lenses and the other stuff as a base for a 720p projector
what if the box sets in fire?
You put it out.

the Light source with a concave mirror would help the display better,, i think, anyway it's always great watching u do
soon as i saw that magnifying glass i knew it was too small lol
make the case 3D printed next time and maybe give it an autofocus feature? (stepper motor moves lcd or lens with ballscrew and a distance sensor and math determine the position of the motor to focus)
You should do trigonometry to perfect it but I bet you can't
Great scott i know where u salvaged the 23.5A power supply .u got from old play station
you're heat would've stayed significantly lower had you not tried to use glue as thermal interface material... smh

Oh, so I have to have a spare projector, a spare high ampere power supply, a spare processor heat sink and a spare lcd to make a projector, sure, makes sense
power supply for 12 volt is from ps3 fat model am i right ?
what about using some thin white cloth fabric tunnel to diffuse the light? like in product photography
