How To Make A Homemade Projector Without A Magnifying Glass
You can make a homemade projector using a few household items without the need for a magnifying glass. Here are the steps:

  • Materials needed:
  • Shoebox
  • Scissors or a craft knife
  • Ruler
  • White paper or thin cardstock
  • Tape or glue
  • Smartphone or tablet
  • Pen or pencil
  • Pin


Cut a rectangular hole in one end of the shoebox using scissors or a craft knife. The size of the hole should be slightly smaller than the size of the white paper or cardstock you will use later.

Cut a piece of white paper or thin cardstock to the size of the rectangular hole you just cut.

Tape or glue the paper to the inside of the shoebox, covering the hole you just cut.

This will be your projector screen.

Turn on your smartphone or tablet and navigate to the video or image you want to project.

Place the device facedown on the other end of the shoebox and center it over the hole.

Trace around the device with a pen or pencil.

Use the pin to poke a small hole in the center of the traced area.

Cut out the traced area with scissors or a craft knife.

Turn off any lights in the room and place the shoebox on a flat surface facing the wall or screen where you want to project the image.

Adjust the distance between the projector screen and the shoebox until the image is in focus.

Play the video or image on your device and watch it appear on the projector screen.

Note: The image may appear dimmer than it would with a magnifying glass, but it should still be visible.

Things To Consider While Making The Projector

Before you start making a homemade projector, there are several things you should consider to ensure that your projector will work properly and give you the best results possible:

Light source: Your projector will need a bright light source to project the image. You can use a high-wattage bulb, a flashlight, or even the light from your phone or laptop screen.

Lens: The lens is the most important part of your projector. It will determine the size and quality of your projected image. You can use a camera lens or a magnifying glass, but if you don’t have access to either of these, you can try using a clear plastic lens from a disposable camera or an old pair of glasses.

Distance and size: The distance between the lens and the image source will affect the size of the projected image. The farther the lens is from the image source, the larger the image will be. You will need to experiment with the distance and size to find the best combination for your projector.

Image source: You can use a smartphone or laptop screen as your image source, or you can print out an image on a transparency sheet. Keep in mind that the image will be reversed when projected, so you may need to flip the image before printing it.

Stability: It’s important to ensure that your projector is stable and won’t move or shake during use. You can use a tripod or a stable surface to hold your projector in place.

By considering these factors, you can create a homemade projector that will work well and give you great results.

How can I project my screen without a projector?

If you don’t have a projector, there are still several ways to project your screen onto a larger surface, such as a wall or a screen. Here are some methods:

Using a TV: Connect your laptop or mobile device to a TV using an HDMI cable. You can then use the TV as a screen to display your content.

Using a streaming device: If you have a streaming device like a Chromecast or Apple TV, you can connect it to your TV and cast your content from your laptop or mobile device.

Using a screen mirroring app: Some smartphones and laptops have built-in screen mirroring features that allow you to mirror your device screen onto a TV or monitor without the need for additional hardware. You can also use third-party screen mirroring apps like ApowerMirror or Miracast.

Using a digital document camera: If you have a digital document camera, you can use it to project your screen onto a larger surface.

Using a DIY projector: As mentioned earlier, you can create a DIY projector using a shoebox, magnifying glass or clear plastic lens, and a bright light source such as a flashlight or high-wattage bulb. This will allow you to project your screen onto a wall or other flat surface.

By using one of these methods, you can project your screen onto a larger surface without the need for a traditional projector.
