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 i wanted to use my laptop, would this system work? assuming that i used a box big enough to put my laptop in. and maybe a bigger magnifying glass.

talk to me on this web site

[tinker234]

i wonder if i add a bulb if it will be brighter

I tried this projector with a condenser lens {picked from a film still camera} ,so that i get a small and dim image

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?

[DuarteLucax]

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....

I'm going to try this one!

WoW I'm going to make this instructable it looks so cool !!! ; - )

[rimar2000]

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!

[DuarteLucax]

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?

[DuarteLucax]

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?

[DuarteLucax]

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.

[arredamento]

very interesting concept and idea, good share!

[DuarteLucax]

Thanks, it's not as good as a real Projector but its fun to watch movies & photos.
