Creating a DIY Projector

Today the use of a projector is becoming common. They are a clever tool to project the tiny laptop screen displayed to a heavy audience. Not only for movies or so, but they are also widely used in the educational field.

For video display, it is crucial to connect them with external speakers for audio output. The markets are flooded with many high-grade projectors, but they are also quite expensive.

How to project without a projector, you may ask, well we have the answer for you. Just make your own projector. Without further ado, let’s dive into the process.

The Tools and Materials:

Before we begin the process of how to project laptop screen to wall without projector, let us share all the necessary tools and material you will need in the process.

Almost all the tools are already present in your household. This method will give you a DIY cardboard projector. You will need,

  • Tape
  • Pencil
  • Laptop
  • Glue stick
  • Smartphone
  • Precision knife
  • Cardboard box
  • Black matte paper
  • Magnifying lens, preferably a large one

Now that we have all the necessary tools let’s start the process of how to project an image on a wall without a projector.

Step no 1: Measure the Size of the Box and Mirror.

You must know the size of the box you are using. Make sure that it is large enough to fit your laptop screen also have a magnifying glass. Using a light source, we will line the lining of the container and pass it through the magnifying glass.

The most important thing to consider is the size of your box. You must correctly measure the length and ensure that it is a perfect fit.

We prefer you use a long box because It allows you to adjust the distance of the laptop and the lens nicely. It will create an easy-to-adjust focus for your projector.

Use a lens as big as your laptop screen. Place your lens on the middle of the narrow side of the box and trace the shape using a pencil.

You must use a light source that can provide more light rays. This will prove a better and brighter image quality.

Step no 2: Dim the Interior:

The next step of how to project without a projector is to cut open the box from the single corner by using a precision knife. Make sure to do it on the box’s edge and avoid damaging the walls. Cover the container’s interior with thick black paper or black matte paper with glue.

The interior of the box must be dim to prevent light reflection. The black matte paper used here is doing this job. In this way, an outstanding image will be projected on the large screen.

Suppose you lack the black matte paper; use black paint in its stead. Just make sure you don’t leave out any adjacent walls, and all of them are painted perfectly.

Step no 3: Add the Lens.

Cut the box based on your lens trace. Both the hole and the lens must be of the same size. If not, then images will not be projected faultlessly.

Install the lens into the hole you made once you cut. If you are using a shoebox, you may have to cut out part of the lid not to cover any part of the magnifying lens.
