What is a DIY projector and how does it work?

A DIY projector is a homemade device that projects images or videos onto a screen or wall using a light source, a lens, and a display device. It works by shining a light through a lens, which focuses the light onto a display device, such as a smartphone or tablet screen, and then projects the image onto a screen or wall.

The DIY projector uses the principle of optics to magnify the image on the display device, creating a larger image that can be seen by a group of people. The lens is the key component that allows the DIY projector to work, as it focuses the light and magnifies the image. By using a DIY projector, you can create a makeshift cinema or presentation setup at home or in a small space.
