So, here we will guide you thoroughly through creating the DIY projector. This will offer almost the same results as a standard projector.

But before talking about the process, let’s look at the cons so that you can decide at the start whether a DIY projector is worth it!

You can still DIY this projector even if you are not creative. Now you must be wondering how to start making the homemade projector. So let’s dive into the process. But first, we will look at the materials so that you can gather supplies before creating.

Materials required

First, the majority range of essential tools is available at home. Thus, this means that it will be high in cost-effectiveness. The only thing might be the lens you can buy from any nearby store. Let’s list all the required materials so you can gather them before the process of reading.

  • Large magnifying lens
  • Mirror
  • Tape pencil, laptop glue
  • Large box size
  • Precision knife Or Scissors
  • Thick black paper

All these tools are available at your home. In case they are not available you can buy them at lower prices. Or ask your friends to bring them along. You can directly dive into the process if you have all the above tools.

Focus Adjustment

First, take a long box of an appropriate size and a mirror. Meanwhile, the aim is to eventually fit the laptop inside the box. Don’t opt for a box that is the same size as that of a laptop. Outer box starting should be with a large box size.

The box size must follow the size of your laptop, preferably a long box. Because eventually, we have to fit inside the laptop in the large box. Also, the box size would affect the ease of focus adjustment. An adjustable focus would require more space.

After choosing the right box, it’s time to install a light source. A light ray will illuminate and pass through the magnifying lens nicely. Make sure that the light is from strong beams to have a brighter image later on. Thereby choose a light source to have a good brightness later. Also, this would enhance the quality of the images. Thus, a better image quality of the picture displayed will be possible.

Choosing Lens slice

While choosing the lens, try to match it with the size of your device. Now it’s time to get into the action with your pencil and precision knife. Trace the lens on the narrow side of the box’s edge. Using the pencil, sketch the lens nicely on the box. Further, with the precision knife, you can cut open the box and make shallow cuts. Make sure that you follow the outline. You can use scissors or a precision knife, whatever suits you. Start from one edge and finally cut the entire line.


You can achieve desired results only by following the traced outline. Make sure the cuts are precise so the lens will fit into the hole exactly.

Here the image will be of low quality because of the mere reflection from the box walls.

Black matte paper

As you will have a dull image on the wall. You can enhance the displayed results by using black paper. Painting might also help, but the black paint dry takes more time. So, it’s better to opt for the alternatives since the black color-coated paper is available in the market.

You will use black matte paper inside your box’s interior walls. Using glue with a brush will facilitate the task. Also, you can opt for the glue stick that makes it handy to deal with. You will apply the black paper on the inside as well as the outside walls of the box interior. Above all, you have to blackout the inside to protect yourself from unnecessary light reflection.

Once you have covered the whole projector box with paper, it’s time to move further.

Inner box

Meanwhile, this additional box is made for the inside of the outer box. The ability of a lens to switch to your smartphone is what we mean when we say “adjustable focus.”

Using the thick black paper, fold four pieces and set them on the edge of the second box.

Make very small cuts along these flaps, and fold them in half at one end. The fold must be precise; therefore, take precise measurements with a ruler. Further, use glue to attach the adjacent sides. This would result in a rigid structure small box. Take the lens, and then use glue to fix it to the box’s inside flaps.

Your phone will now display an image or video upside down. Also, it will be oriented from left to right. This will result in a difficult projection experience, but here we have a solution.

Display settings

You might need to disable the auto-rotate feature on an iPhone, but your Android phone should work just fine. The image should be positioned at a 45-degree angle against the edge. Meanwhile, it is directly across from the lens when you flip the phone over so that it remains head-down.

Draw a rectangle with your pencil immediately above the mirror on the projector’s cover after precisely measuring the size of your phone’s screen. Make the cut disappear with your fine-tipped knife.

You’ll now see that the image coming from your projector appears correct. You should have a professional-level projector for all your purposes once you insert the magnifying glass into the gap you just created.

Cardboard phone projector Settings

Now it’s time to test run and some settings. Suppose you have made every setting on your iphone. Then you have to make a configuration of the rotate screen options. Here you can go to settings> General > Usability > System.

Meanwhile, You will need to download an app from the google play store that rotates the screen in order to maintain the edges straight. You can start moving because the phone has the ability to rotate.

You can watch your favorite movies and TV shows from your TV without returning to your home screen after setting your phone to its default settings.

Adjusting Distance

You must choose the correct focus for your images in order to draw attention to the important details on the wall. Before the photographs are displayed where you want them, control your phone.

Adjust it to the point where the images projected on the wall without a projector are clear and crisp with high resolution. Once you achieve the right point, finally, it’s time to enjoy the device projection.

Sound quality

This DIY projector will not be able to offer an exemplary sound experience since the projector’s lid will not allow the sound to move out. Also, the sound quality will be low than an actual projector. So, it’s better to opt for external devices while projecting laptop screen to the wall.

In this way, the audience would be able to hear a loud sound. External speakers will work great for birthday parties, to watch videos or a movie. You can simply pair the speakers with the phone through bluetooth speakers. A connected wireless external speaker will make sure the sound system and the video experience are perfect.

The playback system may be identified via “Computer Setup” or “Bluetooth Setups.” Or on the other hand, it may be in “Hold” or “Always On” mode when the speakers are turned on. Above all, the projection can be made with other new gadgets as well. But in our opinion, it’s easier to project your phone screen to the wall without projectors.

You can opt for a cheap wireless microphone in case of interactive displays. As in most cases, interactive whiteboards are used in the education system as well as in presentations. A phone’s microphone will also provide the same effect when connected to a speaker.

Image quality

Now let us talk a bit about the image quality of the projected video or projected image. Meanwhile, image quality is an integral part of the projector. It is a general rule. These DIY projectors are great alternatives to expensive projectors in the market. But to a limited point, because we cannot use these DIY projectors for a business presentation.

The DIY projector is only for home comfort. If you use it for official purposes, this might reflect a negative impact on your clients.

Moreover, you might face issues with image quality since the disproportionate magnification decreases the quality irrespective of the laptop’s display. You can improve it with a simple hack of decreasing the image size or scale. Meanwhile, you will notice a significant difference in the crispiness and clarity of the image right away.

However, you still cannot see the fine details or an ideal image of the intended subject.

Above all, with some adjusting, you can get good results comparable to the price.
