Take a magnifying glass and hold it up to the hole in the back of the box. Based on the size of the magnifying glass, reduce the size of the hole until you find the right size. Use duct tape to attach the magnifying glass to the hole.

Step 6: Adjust the focus
The final step is to focus the projection. Move the smartphone forward or backward until the image is clear. If necessary, you can also adjust the focus by moving the magnifying glass or even the size of the hole.

Conclusion

How to Make a Cardboard Projector Without a Magnifying Glass

Projectors are an essential tool for presentations, movie nights, and educational purposes. However, not everyone can afford a high-end projector, which is why creating a DIY projector at home can be a fun and budget-friendly option. This guide will provide you with step-by-step instructions on how to make a cardboard projector without a magnifying glass.

Materials Needed:
- A cardboard box (preferably with a lid)
- A smartphone
- A pair of scissors
- A ruler
- A pen or pencil
- A roll of duct tape
- A needle or a sharp object
- A sheet of white paper

Step 1: Choose the Right Box
The first thing you need to do is to select a cardboard box that can accommodate your smartphone. A medium-sized box would be ideal. Make sure to measure your phone and choose a box that has enough space to hold it.

Step 2: Cut Out a Hole for the Phone
Using scissors, cut out a rectangular hole on one side of the box. This hole should be slightly smaller than the screen of your phone. Use a ruler to measure the size and draw a rectangle with a pencil or pen. Then, cut along the lines with scissors.

Step 3: Create a Lens Holder
Take the lid of the box and cut out a small circle in the center. This circle should be the same size as the lens on your phones camera. Then, use a needle or sharp object to puncture a small hole in the center of the lid. This hole will serve as the point of focus for the projector.

Step 4: Construct the Projector
Insert the lens holder into the hole you created in the box. Hold it in place with duct tape. Then, place your phone inside the box with the screen facing the hole you created. Make sure that it is centered.

Step 5: Test the Projector
Turn on a white background on your phone and place a sheet of white paper behind the hole where the lens holder is located. Adjust the focus by moving the lid back and forth until the image on the paper is clear. The distance between the lens and the paper will determine how large the projected image will be.

Step 6: Fine-Tune the Projector
To get a clearer image, cover the holes and gaps in the box with duct tape to make it as light-tight as possible. You can also add a magnifying glass if necessary, but this tutorial aims to create a cardboard projector without one.

In conclusion, making a cardboard projector without a magnifying glass can be a fun and budget-friendly DIY project. All you need is a cardboard box, a smartphone, and a few basic materials. However, the quality of the projected image may not be as high as a professional projector. Nonetheless, this project can still provide an enjoyable experience for those who are on a budget or want to showcase their creativity.
