Step-by-step instruction

To understand how to make a projector out of the box and phone, we'll look at all the steps in step-by-step with the photo examples:

  1. We prepare the materials and tools for the assembly: shoebox, 10x magnification, office knife, simple pencil,a clip and of course a smartphone. List of materials
  2. Cut out the window to install the magnifying glass. Magnifying glass must be installed centrally. To independently align the lens, we recommend that you draw the diagonals on the right side of the box. So you will know where the center is and then it will be easier to make a smooth cutout.

  4. Preparing the stand for the smartphone. You can use a regular clip, bending it in the appropriate way, or you can make a stand with your own hands from the scraps of cardboard.
  5. Turn off the lights in the room and test the homemade projector. You need to choose the right location of the smartphone in the box. Experimenting with the location of the device, you can choose the most suitable angle for yourself, in which a good image is projected. Perfect location
  6. We load on the phone an application with which you can turn the image. This is necessary, because when you project a video or picture from your phone, the image flips 180 degrees.

movie theater. Here you can use this instruction to make a projector yourself at home. As you can see, there is nothing complicated and you do not need to spend money to buy materials.a box, an insulating tape and even a magnifier can be found in your own workshop.

What else is important to know?

If you want the image on the wall to be of good quality, it's best to use a tablet or laptop instead of a phone. In this case, the magnifying glass should be larger, becausethe size of the screen itself is many times larger. An example of how to quickly make a projector from a laptop or tablet, you can see in the photo below:

Another important point - if the homemade device projects a not very good picture on the wall and while you are already trying to change the location of the smartphone, it means the case in the lens. Try to replace it with a better one, if before buying a cheap option. The most suitable magnifying glass is Soviet.


In addition, I would like to draw attention to an important nuance - to make a homemade home theater showed a clear picture, brightness on a mobile device should be put on maximum. Improve the clarity of the projector by painting the internal walls of the cardboard box into black. Another simple way is to install an additional magnifying glass inside the box.

This should look like a slideshow on the wall

To the wall on which a slideshow or video will be displayed, there are also requirements. It is best to direct the projection to a special canvas for the projector, but if there is not one, a paper of size A1, fitted in a frame, is suitable. Here I would like to clarify that you can use this home-made cinema at home only if the room is dark enough. Light will negatively reflect on the quality of the picture.
