With the continuous progress of science and technology, our life has become more and more convenient. Mobile phones have become an indispensable part of our lives, but sometimes we need a bigger screen to enjoy a better viewing experience. At this time, the homemade mobile phone projector has become a very good choice. Today, we will teach you how to create a high-definition cinema experience with waste materials.

material preparation

First, we need to prepare some materials. These materials can be found in the trash can at home or nearby. The specific required materials are as follows:

1. One carton

Step 2: Magnifier

3. Some black tape

4. A blank sheet of paper

5. A mobile phone

Production steps

1. First, we need to cut one side of the carton. This incision should be the same size as your mobile phone.

Then, we need to cut a small hole in the remaining paper box. This hole should be as big as a magnifying glass.

Next, we need to fix the magnifying glass on the carton with black tape. Make sure that the convex surface of the magnifying glass faces the inside of the paper box.

Then, we need to cut the white paper into a piece the same size as the carton.

5. Stick white paper on the other side of the paper box. In this way, we have a surface that can reflect light.

6. Place the mobile phone at the incision of the paper box. Make sure the phone screen is facing the white paper.

7. Finally, aim the other side of the paper box at the wall or white screen, and adjust the position of the magnifying glass until the image on the screen is clear.
