Using a phone just for voice and data communications is more common than you would think. You’re correct in some ways. Nowadays, thanks to advancements in technology, you can accomplish just about anything with your smartphone. Another way to put it: You can use your smartphone to display an image.

  • Precision knife or scissors
  • Magnifying glass
  • Mirror
  • Ruler, pencil
  • Double-sided tape, brush, and glue
  • A shoebox or something similar
  • Black matte paint or thick black paper.

Step 1) Use The Right Box And Mirror

To create a magnifying glass, the box must be lined with a light source and a mirror. It uses your phone’s built-in projector to display a large image. More light is required to produce a more vivid picture. For the greatest results, you should keep your phone as far away from the projector as possible. As a general rule, you can always find a case that fits your phone. For an exact self-reflection, you will need a basic rectangular-shaped and phone-sized mirror.

Caution: Using a ruler to accurately calculate may lead to errors.

Make a few incisions at the bottom and top after allowing the flaps to extend a few inches. Apply glue to the adjacent flaps in order to secure the flaps together. Structures benefit from stiffening like this. Afterwards, add adhesive to the box’s interior flaps.

Once the phone has been turned off, it must be laid on its side for safekeeping. A mirror may be used to fix the location of the left image. The mirror is aligned perpendicular to the lens to provide this effect.

Step 6) Create A Window For The Phone

Take a look at your phone’s display and compare it to the mirror on the projector. The rectangle must be subtracted accurately. Finally, use the hot glue gun to secure phase 3 to the board. You’ve gotten your hands on a portable projector in a flash. With paint or other materials, the projector may be given a gloss.
