Portable Smartphone Projector

Instructions

1. Measure and cut a hole in one side of the cardboard box to fit the magnifying glass snugly. 2. Attach the magnifying glass to the hole using tape or glue, ensuring there are no gaps. 3. Paint the inside of the box black or line it with black paper to reduce light reflection. 4. Create a phone holder using additional cardboard or a small box that can hold your smartphone securely. 5. Position your phone at the back of the projector, ensuring that the camera is aligned with the magnifying glass. 6. Adjust the distance between the phone and the magnifying glass to focus the image on a wall or screen. 7. For stability, you can use a small tripod or a stand to hold the projector in place during use.
