LED Projector From Old Phone

Turn your movie nights at home into a theater-like experience by transforming your old phone into a projector. With a little DIY magic, you can repurpose your old phone screen and create a home theater setup that will impress your friends and family.

To make your own DIY phone projector, you’ll need a few simple components:

  1. An old phone with a functioning screen.
  2. An LED chip.
  3. A lens from an old camera.
  4. Cardboard or a suitable material for the projector body.
  5. Tape or glue to secure the components.

Start by disassembling your old phone and removing the screen. Carefully detach it from the circuit board, preserving the connecting cables. Next, construct a housing for your projector using cardboard or a similar material. Cut out a rectangular shape to hold the screen and create a box-like structure to house the LED chip and lens.

Once your housing is complete, position the screen inside, ensuring it is secure. Attach the LED chip above the screen, facing towards it. This will provide the necessary light source for your projector. Finally, place the lens in front of the LED chip, allowing it to focus the light onto the screen.

When everything is in place, connect your phone screen’s cables to a power source and turn it on. Adjust the focus by moving the lens closer to or farther from the screen until you achieve a clear projected image. You can project the image onto a blank wall or use a projector screen for optimal results.

“Creating a DIY phone projector not only repurposes your old phone but also allows you to enjoy a home theater experience at a fraction of the cost. It’s a fun and rewarding project that brings your favorite movies and videos to life on the big screen!”
