You can create a cardboard phone projector. Don’t worry, you don’t need to be a creative person to cope with that task. 

Materials needed. To construct a cardboard phone projector, you will need a cardboard box (preferably a long box), a magnifying lens or magnifying glass, a precision knife, thick black paper (black matte paper), tape pencil laptop glue.

  • Step 1. Prepare the box. You’ll need a precision knife first.

Begin by cutting one side of the cardboard box with a precision knife, leaving the box’s edge intact to act as a stand.

  • Step 2. Line with black paper. Line the box interior with thick black paper or black matte paper to minimize light leakage. Keep in mind that light reflection from the box walls causes noise in the project images.
  • Step 3. Create a phone holder. On the side of the box, opposite the open side, create a holder for your phone’s screen using cardboard or any suitable material. Ensure the mobile screen is positioned at the focal point of the magnifying lens. To project pictures accurately, the hole and lens should be the same size.
  • Step 4. Attach the lens. Secure the magnifying lens (you can also use a fresnel lens) in the opening of the box opposite the phone screen holder. Change its position until you achieve the adjustable focus.
  • Step 5. Test and refine. Place your mobile phone in the holder, turn on a white mobile screen or a blank document, and position the box so that it projects the mobile screen onto a wall without a projector. Moving the phone and changing the lens position will help you to create an adjustable focus.
