how to project mobile screen on wall without projector

Hello! While a projector is typically used for such purposes, it's possible to simulate a similar effect with certain methods. Keep in mind the results won't be as clear or large as with a projector. One of the easiest ways is to utilize a magnifying glass and a shoebox to create a homemade projector.

First, cut a hole in one side of the shoebox that the magnifying glass lens can fit into. Secure the lens, and place your phone inside the box with the screen facing the lens. When you point the box towards your wall in a dark room, the image on your phone's screen gets magnified and projected onto the wall. To focus the image, move the phone closer or farther from the lens. Remember to lock your phone's screen rotation.

That's correct, due to how the lenses work, the image projected would be inverted. The simplest way to correct this is to flip your mobile device upside down when you place it into the box.

You're welcome! Have fun with your DIY project, and feel free to reach out if you have any more questions.
