Step-by-Step Instructions
1. Start by measuring the lens of the magnifying glass. Use a ruler to determine the diameter and make a circle outline on one end of the cardboard box.
2. Carefully cut out the circle using scissors or a craft knife.
3. Fit the magnifying glass into the hole you just cut and secure it in place with black tape or duct tape around the edges.
4. Create a smartphone holder inside the box. You can use another piece of cardboard to create a platform that holds your smartphone at the right distance from the lens.
5. Ensure the smartphone is positioned in such a way that the screen faces the lens directly.
6. Close the box and ensure it is light-proof; seal any gaps with tape.
7. In a dark room, place your projector against a wall or a screen. Adjust the distance until the image is clear.
8. Play a video on your smartphone and enjoy your homemade projector!
