Introduction: Make a Cheap 3$ Projector

I'm gonna show you how to make your own 3$ Projector with things that you probably already have. Its cool for you to watch your photos and movies and it's portable so you can take it anywhere.


To make your own 3$ Projector, you will need:

1 - Magnifying Glass
2 - Hot Glue
3 - Cutting Tool
4 - Box(any kind of box will work, i'm using a Cardboard Box)

It's not as good as a real 200$ Projector but its good for a 3$ Projector...    : )

Step 1: Preparing the Magnifying Glass

Remove the Magnifying Glass from it's casing until you only have the Magnifying Glass itself. Use a plier or something like that to remove the case. You can also use others Magnifying Glasses to make this projector.


(If you need help, see the photos or comment)

Step 2: Preparing the Box

Now just make a hole with the size of the Magnifying Glass, mine isn't a circle, it's a square so i have to make the hole with the size of the circle part that magnifies. I used a bottle cap that was just the size of the Magnifying Glass(the circle part), to mark where i needed to cut.

Use the Cutting Tool to make the hole where your Magnifying Glass will be and, if you want, you can use a pen(with the color of the box) to paint the edges of the hole.

Step 3: Making the Projector

To make the projector, hot glue the Magnifying Glass inside the Box and let it dry.


(If you need help, see the photos or comment)

Step 4: Using the Projector

To use the projector you will need your mobile phone or a mp4, just put the mobile phone or mp4 inside the box, i used some Playdough(plasticine) to hold it(see the photo). The image will be upside down so you need to flip over the phone so the image that will come out is normal. If you are using an iphone like me, you will need to turn off the accelerometer that makes the screen flip when you move it upside down.


(If you need help, see the photos or comment)

Step 5: Finished Projector!

That's all!

The finished Projector will look like the first photo.
And projecting a video will look like the second photo(it looks a little bit worse than it is because i took the photo in the dark).

Is there a way of double inverting the image so it flips back to the right way up using two glasses?

had to figure a way with the small box and magnifying glass I had, but I impressed with a "first try"

what kind of magnifying glass did you use?

author
jmagana5 made it!(author)2015-03-16

a standard glass from a set of "helping hands"

I tried this but I only get a white light image. I tried focusing back and forth but nothing happens. What magnifying glass did you use? I think it's the problem. When I first tried it, I use my moms eye glasses (which is concave obviously) and I see some flipped blurry image with colors slightly visible so I thought It would really work If I buy a real magnifying glass but It does not work so I'm thinking that the magnifying glass needed should be concave.

Interesting project, but don't you need to focus the image? Does it come out clear enough? How big is the image and how far can you project it?

author
DuarteLucax made it!(author)2011-09-15

To focus the image I simply move the box(projector) forward, or backwards. If you put the box to far from the wall, the image will get a little bit bigger but blurred. The image is a little bit dark compared to a real projector, but for 3$ what could we ask more? Thanks

Worth going tothe dollar store just to get a couple of cheap lenses. Wonderif two lenses will get the image without inverting it....

You need a mirror in order to put the image in normal mode. Otherwise you can't read texts as you do, left to right. Anyway, good try!

author
DuarteLucax made it!(author)2011-09-08

Yes, you're right. I tried to see a text and the words were backwards. I didn't even know that because i just use the projector to see photos and movies without subtitles. But still is good to watch photos and small movies(without subtitles). Thanks for the comment!

So...many projector projects specify fresnel lenses and other complicated bits. Why doesn't this project need those?

author
DuarteLucax made it!(author)2011-09-07

Because this is just going to amplify the light(photo/movie) from the LCD of your cellphone into the wall. It's not real Projector.

ha! fun! how does the image look?

author
DuarteLucax made it!(author)2011-09-07

The image isn't that bad for a 3$ Projector, you can only see it with the lights off but still is fun the watch movies & photos. The image is a little bit more darker than a real 200$ Projector.
