My easy tutorial of how to make smartphone projector allows you to increase your phone image up to 15 times more! It means that you can get an image about 60 inch! For this DIY Smartphone Projector (that will REALLY WORK!) you will need: 2 shoe boxes (2! not 1!), magnifying glass (I used cheap magnifying glass which diameter was 75 mm), electrical or black duct tape, scissors and knife, black paint, a pencil and a ruler, smartphone (or even PAPER PHOTOS!).
First step is to connect 2 shoe boxes. Mine were 33 cm each. So I've got 66 cm projector. You can take 1 large box (60 cm), but it should be narrow. How to connect boxes - watch in my video tutorial.
Next step - is to cut off a hole for magnifying glass.
Next - to cover all holes in boxes to make the light pass through the magnifying glass ONLY!
Then paint inside of your boxes black! I used watercolor, but you can use gouache, spray paint, just glue inside part of boxes with matte black paper - whatever!
You'll need a smartphone holder, so I made one out of a plastic bottle bottom (watch in my video tutorial).
Set the holder to the inside back part of the first box (that one which is without magnifying glass). Put your phone to the holder (screen should be turned to the magnifying glass).
Important! Phone settings! Turn phone screen brightness to the maximum. Turn off screen rotation. Flip your phone upside down (so ppl in video or photo will be turned - their feet will be up, and their heads will be down).
About focus and distance: tune the focus with moving your smartphone (with holder) backwards and forwards in the first box. Here are few tips about distance:
1. Distance from phone to magnifying glass - 60 cm, Distance from magnifying glass to the wall - 1 m, image size - ~8 inch
2. Distance from phone to magnifying glass - 50 cm, Distance from magnifying glass to the wall - 1.5 m, image size - ~15 inch
3. Distance from phone to magnifying glass - 40 cm, Distance from magnifying glass to the wall - 5 m, image size - ~60 inch
So, turn off light in your room and start the movie! :)
You can also project paper photos! Use a flashlight for this. Watch in my video tutorial how to set it right.
Good luck! - แนวปฏิบัติและการใช้ชีวิต
I am extremely impressed! This worked amazing, just not with very high quality - but certainly very clear. I made my projector size over 20 times bigger than my phone size! I would also suggest that if you are using this for karaoke, it isn't the best as the words come out backwards. TIP: to make the projector as big as you like, make more distance between the wall and the projector!
Also, if you have a well sealed box, don't worry about adding tape or paint to the insides because it worked for me just fine!
Hope this helped everyone who wasn't sure if it would work!
I did this with an iPhone 5😄
The only project DIY that gives some insight about the distances and results.
It's really great, perfect
@Matthew Jayceon did it work?
This is probably the best one of these I have seen, definitely am going to try it out
finally, your video helped me to get this projector to work. The 2 box design and those measurements really helped
Thank you very much :-)
+IdunnGoddess If I used a stronger lens power on the magnifying glass could the picture get bigger?
+Carrwn Lenore on the projector*
and using a stronger lens would also mean using a different setting of measurements for the projector.
you could try using different settings to make the image better.
+Carrwn Lenore The problem with this thing is that the brightness of the smartphone screen is limited and the brightness of the wall image decreases as the size increases. So you can get a lot larger image but the brightness will be so low that it will be barely visible in a complete darkness. It's pointless even as seen in the video. That's why we are using a projectors.
Why 2 boxes??
Ooooh, tis is absolutely awesome, very interesting indeed! Thank you for the video!
THIS WAS THE FIRST DIY PROJECTOR VIDEO I HAVE EVER WATCHED AND I GOT AN AD FOR PROJECTORS!!!!!!!!
You know why this worked better than 99% of the other smartphone projectors? Because she painted the inside black. I made a homemade projector in the early 2000's, before smartphones existed, using an old CRT monitor. Every tutorial I read (there wasn't TH-cam then!) told me to paint the inside black, because any other color will reflect light, and light reflection will reduce the quality of the picture. These other smartphone projector videos you see on here, the person making it doesn't paint the inside black and then complains it sucks! Research people, Research.
School's out! FINALLY I can get back to DIY. will try this soon!
IdunnGoddess do you have a sister and she have her channel

Anam Fatima fuckit
Sees the comment 3 years later...
Anam Fatima how did it go?
And then grab a $5 Bluetooth speaker from five below
😂
Trap Central help
Armeezy Official lol true😂😆😆😆
I have a 4 dollar one
Armeezy Official I just did hat today
Wow, can't wait to try this! :)
I am trying this soon!! Can't wait!!!!
Good one. 👍
I was planning on making one of these. you've illustrated well.
That projector test reminds me of movie "Sinister".
great idea and execution. I wouldn't have though about painting black for less light reflection. Nice project!
I'm impressed! Well done!
Love this idea! However won't the volume be kind of quiet? I guess you could hook your phone up to a Bluetooth speaker!
you can make a plug hole. just make sure that it perfectly fits so no outer light will go in. then there u go, :D
cool😊😊😊
Sadie Black hello thanku
I'm going to make one and just used my Bluetooth headset
No its actually relatively loud, just put your volume all the way up

Me: 15 x 0 = 0
Good one😂
So it didn't work ?
@@hsnztn2802 it didn't work
@@viejaspeliculasfilipinas3621 it worked for me , but I'm not sure if 15 means that the projected image is like.. 15 times the original photo. If yes, then yes
However.. it's blurry of course..
And upended :/ .. upside down
I still have the box on the top of the cheuveniera in my grandparents' house.. for some reason.. i cut and assembled it.. it was nice and warm to see the projected photo at night
@@hsnztn2802 ok
Wow that is truely amazing..
love ur videos sooooooooooooooooo much watch them all day every day
I was watching this with a projector lol
lol
Lol
Haha
Hahaha lol 🤣 🤣🤣🤣
Haha
Now i can watch a movie while having a glow in the dark pool party.. :O im gonna make the outside glow in the dark! Just so everyone can see it :)
@LimeJuice no it isn't just use your brain adjust it
@@aria-lw1lq it is a pain to get right every time
@@aria-lw1lq well it works but for me i had to make to room 100% dark and also i downloaded an app and i put the video sharpness to 50% and brightness to 200% because otherwise it wasn't bright enough. And also i put it on a white smooth surface. I watched a couple episodes from tv shows but movies i don't it will be great because they are usually darker. Also you have to adjust it just enough because sometime you can go crazy knowing you can do a little better but you usually mess it up. So if you do this. Just adjust it and then don't touchit
This is how we make my own silent movie now. :-) thank you for sharing!
Great idea! Thanks for sharing!
It's amazing
I love it I will try it all I need is a magnifying glass
Talita Finau same
You are awesome me and my friend are living in a P.G and we made it. Working perfectly fine. All the best you did a fantastic work... :-) :-) :-)
I love this projector video
It works thank u
this us a real work in viewed projection quality and size please told me
How it works explain process to me
It worked perfectly.👍
But When I watching a video , the whole video looked like it was on a mirror
All hail the DIY queen
Its amazzzing ! I will surely try this !!! Thanks
Brightness has left the chat
I got a projector ad. XD
Lol me tooo.!!

The best description
That was an awesome video!!!!! I'm gonna try it. Thanks
JFC Get a bigger paintbrush, girl.
That must've taken you like two days to paint that with that little brush
Spray paint it
use black tape or black sheet and paste it.... its easy,, this project is only for time pass.. not possible to enjoy movie.
on
Or use black gouache, dip a sponge in it and use it to paint the box.
@@m1glr4mrz smartest comment yet.
A bit complicated but a sweet Idea. Might not be the best thing though. Use any app which can transfer your laptop's screen on the cellphone. Use wifi direct so that The least amount of lag is present. Flip it and put inside the projector. Then Use your laptop to play a game or something.. Probably nothing which requires precise controls.. Play something like.. erm.. ah.. Okay something like battleblock theater. Any 2d game or a less Accuracy hungry game ( Probably not a racing game) And you can enjoy a projector which not only is capable of projecting your phone but your pc too. Cheers. (P.s already done it)
The best and accurate video in
Whole TH-cam
actually I love this video idea how you made...love your style
Very cool video :) I just have couple of questions regarding the set up.
1) If I want to use my 7" Tab, which Lens should I prefer - 4 Inch with 2.25X OR 3 Inch with 5X ?
2) Also, what should be the ideal Distance from Tab to magnifying glass to get 40" (or so) projection...is there any formula?
Thanks!
5 years and no reply. ☹️ Where you at in life ?
@@Dan42137 😂😂
@@Dan42137😂
To adjust the distance to the wall or the phone, also the size of the image, you can calculate like this:
Distance from the glass to the wall / distance from the magnifying glass to the phone = the size of the picture on the wall / the size of your phone (use inch)
Hmm it's not always accurate 100% due to some other small effects, but almost right.
Have a nice day ^^
If the magnifying glass more far from the phone its mean bigger or more small
Sorry for my bad english
Excellent - I'm going to try it.
Its seriously, a good and easy way to make a home projector..........! I liked this video.....! Hope you will make such awesome videos for us again......! Thanks........!
One question- does it really projected at 60in . its the video recorded by putting the mobile close to 10-15in projection??
It can be increased
By this we will experience a threater felling and for the volume we can have a speaker 🔊
I love your channel!!!
Most helpful video ever thank so much
This idea is really great! It’s so cool! But unfortunately when we tried it it was really really small, the image, and it was really blurry. We even tried to use the measurements but the DIY still didn’t work. Great idea though!
You saved me time and boxes 😂 thank you
it doe kinda work. but not very HD or something. but for the 3 euros is spent on it? it looks fun.
thanks
Just adjust screen. Find the best position or put white background on wall
Woow, well done! :D
awesome tutorial. saving me so much money.
i tried last night but did not work :( pls help i really wanna make a right one to surprise my lil bro help pls
I made one...It was decent. You have to use it in a very dark space
I have S3 too, very cool video !
അടിപൊളി സാധനമാണ് കേട്ടോ !
Amazing....!
I TRIED THIS LIKE RIGHT NOW AND IT DOESN'T WORK I'M TELLING YOU
It works for me, but the visibility is poor 😢
It's fake
@@JazzBilon-vf9um Go study Ray optics dude
Je to pěkná debilovina 🙄🤦🏻♀️ Obraz je na h...🥴🫣
@@fugaallegro you need to put magnifing glass inside the box in front of phone and the lens
muito bom D+
thx this is such a good science fair project
Yes, I'll try this in quarantine for watch TV thank you
there's no image coming out: (
Doesn’t work just so everyone is aware it show the smallest little screen that is blurry
Yohan J only if you hold it right up next to the wall and you like blurry
I've done this and it works, you just need to adjust your phone
@@Dg55345 it only works for certain types of magnifying glasses. I have two magnifying lenses, one has a lower focal length while one has a higher focal length. The higher one is the only one that worked for me.
@@PinkStratovolcano yea
Thanks! Will rather try this today!
Nice work 👍
idunn goddess, hlp me how to get a big screen
Why its upside down and evem when iturn off screen rotation it still rotating
i love idea, simple but the best............thank you to share!
i am taking this tutorial to do this at home thx so much cant wait to make it very helpful 😄
I tried this for my school science exhibition but it doesn't work..
but looks good
I did for myself ,it works but crappy image
hi...
can any 1 say me
what is the power of that magnificent glass
Good qustion
love this idea
Wow... Beautiful... Nice.
What type of magnifier do you use?? my magnifier makes a blur circle around the video :((
try using two magnifying glass that worked for me
Sapns
hey guys if you want to get know knowledge of magnification like how much distance is suitable for perfect image or the radii of magnification glass just follow simple physics chapter name magnification there they will provide you a simple for formula for measuring distance and etc
+Krishna Gupta So if I want to learn something I should look it up in a book? GOD DAMN you are a fucking genius!
+ipissed shhh he's indian he doesn't understand
where did he mention a book... you need someone to make a video for you for everything?
agree
Yeah dipshit
Great work 👍
Thank u so much for the distance measurements. It worked out well for me😊
Really the sized was increased on the wall please tell me is it true
🙏🙏
hiiiii love ur channel.. i trird making this box but it just doesnt work: (
the only projection i get on wall is small but so blurry... aby tips how i can fix? thank u!
Try to use other magnifier glasses or adjust the phone
I got the same but my phone brightness was up to max
Can I just buy a black shoe box as an alternative for the painting?
Dorothy Grace no u have to paint
Good Kid lol
Yes that works too
So far best way o make this ty :3
liked the idea of projecting photos
I tried this project step by step. finally, the image size was smaller than the image on my phone. :(
I know it's kinda late but you should have centered the lens perfectly first and trial and error with the distance.
@@jagadishgospat2548 kinda late ?😂
May I know how to calculate the distance between phone and the image size? Thanks.
+IdunnGoddess or talking
+Priyank mistry maybe it would be easier for me to follow her tutorial at thus point do the boxes have to e black?
christian doodles: Not have to, but better if you paint them black.
If the magnifying glass is 2m away from a wall your phone should be 1m away from the glass. So if u have a big phone (I did it with a small one) u should just go farther. Am I right?
+IdunnGoddess Il💖ve you
This is best with Calculations 🙂 👍🏻👍🏻👍🏻 ❤ it
Thanks, always keep up your good work...Thanks from Sri Lanka
Wow
I ma indian
Do you have to paint the box black
Dara Stack it makes it better
Cool! Cool! Cool! I like your channel!
So cool!!
gosh u ve got patience and lots of time ⌚. thumbs up
Has nyone tried this and succeeded or failed? How big is the projected image?

Thank you saving me a ton of money !
cool! very helpful!
why would you put paper pictures when u can just put a slide show on ur phone
hahahahhaha i laughed so hard in this
lol
what if you don't have a phone ?
true I guess..🤔
Believe it or not, long ago.... The only way to have photos, was to have an actual Camera and have them developed! Crazy right!
I did it but it's only projecting white light
BaconRising adjust the distance of smartphone to the Lense
Mine was projecting white light too, but I found out that if I double my magnifying glass It will work and it did
BaconRising its working on a small magnifying glass for me (i did the big one first but it only shows white screen so i tried the smaller one)

Saitama sensei What do you mean?
Thanks bro it really works
this is a good project to do with older kids good stuff
It won't project on my wall and my little brother and sister really want to do this how come it is not going on the wall
Same
Hi! IT did the same to me! Try to turn around the glass so the side you had inside comes outside! :) IT worked for me!
It projects on my wall but I can't get it to focus all the way?
woa ahhaha i should do this
