In todays fast-paced world, technology has made our life much easier and comfortable. With the invention of smartphones, we have the world at our fingertips. However, sometimes we need to amplify the screen of our smartphones for a better viewing experience. This is where a smartphone projector comes in handy, as it can turn any surface into a big screen. In this article, we will discuss how you can make your own smart phone projector.
Firstly, the basic principle behind smartphone projection is light amplification, and you can achieve this with a magnifying lens. You can get one from an old projector or a magnifying glass. Besides, you will need a shoebox, tape, black paper, cardboard, scissors, ruler, and a marker.
The first step is to trace the outline of your magnifying lens on the shoebox with the marker. Cut out the traced circle with scissors. Then, turn the shoebox upside down, and trace the outline of your smartphone on the opposite end of the box. Cut out the traced rectangle with scissors, so the smartphone can fit into the hole.
The next step is to use black paper to cover the inside of the shoebox. This is essential to prevent light from reflecting off the interior of the box and interfering with the projected image. Cover all inside walls, except the lens hole and smartphone hole.
Now, take the magnifying lens and position it over the hole you cut out earlier, so that the flat-side of the lens is facing the smartphone. Tape it securely into place.
The final step is to make a cradle for your smartphone. Measure and cut out two cardboard pieces for the sides of the cradle and one piece for the base. Tape the sides on each side of the smartphone hole. After that, tape the base underneath the sides.
Your smartphone projector is now ready for use. Set up your projector in a dimly lit room or place a piece of white paper against any surface where you want to project your image. Place your smartphone in the cradle, with the screen facing down, so that the projection is right-side-up. Turn on the phones screen and adjust the focus of the image by moving the smartphone back and forth until it is clear.
To conclude, making your own smartphone projector is easy and inexpensive. With a few everyday items and a bit of ingenuity, you can enjoy entertainment on a large screen without spending a fortune. Try it out and enjoy the big screen experience from the comfort of your own home! |
