How to Make a Projector at Home? (Step by Step Guide)

A projector is an important device to consume media and enjoy different entertainment sources like movies, dramas, or games. But if you are a person who can’t afford a projector then in this article I am going to share a step-by-step guide to making a homemade projector.

This guide is also helpful for children who want to prepare a homemade projector as a fun activity or to learn something new. This guide is simple you need a material that is easily available and you do not need to involve in any difficult job to do that.

All you have to do is read these steps carefully and implement them to prepare a projector without much hassle.

Let’s begin with the material:

Step No. 1: Gather the Material

The number one step is to search for all the important material and gather it in one place before starting the real work. In the process of making a homemade projector you will need the following material:

  • A smartphone
  • A shoebox
  • A Magnifying Lens
  • Glue and Tape
  • Foam
  • Projector screen (You can also use any white surface)

You will also need other helping instruments like scissors and a scale for measurement. These all objects are easily available and most probably you can find all of them in your home store or if it’s not there then you can buy them from a nearby store. Keep in mind that the lens you will need for this process should be magnifying.

Now we have all the material for the second step.

Step No. 2: Setup the Box

In this step, you will set up your box with the help of glue. All you have to do is make the box strong so that it will not lose its sides when you will add a lens and mobile in its frame.

As it is like the basic structure, so you need to be extra careful about it. Use glue to keep all the corners and sides of the box intact. You can also use tape to add more strength to the box.

After this step, we can move to the next step.

Step No. 3: Fit the lens in the Box

In this step, you will set up the box to fix a magnifying lens on its one small side. To do that first of all use a magnifying lens and place it over the small side of the shoebox and then use a pencil to create a circle around the lens.

This circle should be matched with the length of the lens and then cut that circle by using a scissor.

Now you have a hole, place magnifying glass in it and carefully glued it together with the box. The glue should not fall on the lens screen. It can blur the image and you may have to do the process again.

Step No. 4: Set the Magniysing Lens with Construction Line

The construction line is the line on which you will set up the lens and mobile phone screen. This line helps to focus the mobile screen on the magnifying lens so that the lens can enlarge the screen and show it on the projector screen. You can use a scale to draw a central line from the lens to the mobile phone.

Step No. 5: Set up your Mobile Phone

A mobile phone is an important part of this whole process and you can’t go without setting it up. To prepare a homemade projector, you will need a mobile phone with a good screen.

Go to settings and increase the brightness of the screen and remove any kind of eye protection settings. Your mobile phone’s battery should be fully charged. The reason being if the battery of the mobile is low then you may have to charge it again and the whole process of using it as a projector will stop.

Step No. 6: Use Foam to place the Mobile Phone

In this step, you will need a foam box. This foam is needed to keep the mobile inside it so that the mobile phone does not face any kind of scratches and you can easily move it around for the perfect position and outcome.

Use a scissor or knife to cut through the foam. The area you will cut should be enough to keep mobile in it.

Step No. 7: Use glue to keep all things Intact

In this step, you need to intact all things together for the final result. To hold the mobile phone with the foam box use tape. You can also use glue to strengthen the corners of the shoebox.

But you need to remain extra conscious during the use of glue. Keep it away from the lens and mobile phone screen because it can cause problems for you. So use it carefully and only where it’s needed.

Step No. 8: Use a Bluetooth speaker for Sound

You can’t think of a projector without a speaker and in this homemade speaker you can’t use the inbuilt speakers of a mobile phone, So to enjoy the sound you need a Bluetooth speaker.

Bring a Bluetooth speaker near the mobile phone and connect it through Bluetooth. After confirming the connection keep it at a normal distance from the box.

Step No. 9: Set the Position of Mobile Phone

The next and second last step is the position of the mobile phone inside the shoebox. This position is essential for the outcome of this homemade projector.

You need to test different positions and when you think the result is okay then place the mobile phone in that position by supporting it with something hard.

Step No. 10: Enjoy your Homemade Projector

And here you go, your homemade projector is ready and you can enjoy your time by watching moves on it. Open the videos file on your phone, play a video, keep the volume high, and set the position of the mobile phone behind the lens for best results.
