How to Make a Mobile Phone Projector
If you want to watch a movie or present a slideshow on a big screen but dont have a projector, you can turn your smartphone into one. By following these simple steps, you can make a mobile phone projector in less than an hour.
Material
To make a mobile phone projector, you need a shoebox, a magnifying glass, a knife or scissors, black paint or paper, tape or glue, and a smartphone.
Step-by-Step Instructions
1. Find a shoebox that fits your smartphone. Cut off one end of the box, leaving three sides and the bottom.
2. Paint the inside of the box black, or cover it with black paper. This will help to absorb any reflections and increase the contrast of the projected image.
3. Find a magnifying glass that fits the area where the cut-out end of the box used to be. Place the magnifying glass frame on the box, so the concave side of the glass is facing the inside of the box.
4. Trace around the magnifying glass with a pencil and then cut out the hole with a knife or scissors.
5. Cut a small hole for the smartphone camera at the opposite end of the box. Adjust the holes size to fit the smartphones camera.
6. Place the smartphone on the side of the shoebox opposite to the magnifying glass. Make sure the camera lens of the smartphone is facing the hole you just cut.
7. Turn on your smartphone and go to the video or slideshow you want to project.
8. Place the box in a dark room and point it at a white wall. Adjust the distance between the smartphone and the magnifying glass until the projected image is in focus and large enough for your needs.
9. Tape or glue the magnifying glass in place.
Congratulations! You have just made yourself a mobile phone projector. It works by magnifying the smartphones screen and projecting the image through the magnifying glass onto the wall. You can now enjoy movies, videos, or slide shows on a larger screen without the expense and bulk of a physical projector. This is a low-cost and fun solution you can create right at home. |
