This is a project I have been working on and experimenting with for a few years. I finally managed to get the right projectors together to make a DIY home projector that will allow you to show images on any reflective surface (mirror or window).
This is a project I created to create a low-cost projector. A mirror was attached to the front of the cardboard box and then a cheap plastic lens was used to make the image appear in front of the box. The light from the projector is reflected onto the box and we get a nice bright image inside!
How To Make A Homemade Projector With A Mirror at Home?
A mirror is required for this project. This is because you will use it to reflect the image of the projector onto a surface such as a wall.
It is very important that the mirror is clean and clear. You may also use a sheet of glass. You will need to get a piece of cardboard to use for the box. You can buy this in any art supply store. You may also use a small paper box.
This is what you need:
- A cardboard box
- A mirror
- A lens
- Magnifying glass
- Thick black matte paper (alternatively, brush and paint)
- Tape, normal or double-sided (can be substituted with glue)
- Exacto knife or precision cutter (or scissors)
You will first cut the lens from the cardboard box. You can do this using a utility knife. Cut it in half so that you can make two lenses. Then, cut them in half again and again. You will need a total of six lenses.
Cut the Box
To separate the box, you will need to cut off the top of the cardboard box. After you remove the lid of the box, make a mark on the cardboard so that you can keep it in place while you are cutting the rest of the box.
The next step is to cut out the hole for the mirror. Use the ruler to measure the distance from the edge of the box to the corner.
Once you have the right measurement, make a mark on the box. Use your ruler to cut out the space between the mark and the box. Make sure that you do not cut through the box when you are doing this.
Do the same for the opposite side of the box. You may use scissors or an Exacto knife. You will need to carefully cut along the marks to separate the two sides of the box.
You can use the back of the box to hold the mirror. This will prevent it from slipping. The next thing you need to do is to cut out the hole for the lens.
Place the cardboard in the mirror and use your smartphone or magnifying glass to look at the image. Place the phone or magnifying glass on the cardboard to adjust the size of the image.
Use the ruler to measure the distance from the corner of the mirror to the center.
Cover the Inside of the Box
Now, you need to darken the inside of the projector. This stops the light from dispersing and reflecting on the surface of the film. You can do this using paint or a pencil.
It’s best to do this on a non-white background. You need to cover the white screen of the projector. First, put the lens of the projector on the cardboard box.
Then, open the projector and look inside. Use a pencil or paint to cover the inside of the projector. Start from the bottom and move upward until you reach the top. Do the same thing on the left and right side of the projector.
Place the Lens
You need to place the lens on the cardboard box before you turn on the projector. This is to make sure that the image is focused properly. This is to prevent blurry images.
When you turn on the projector, the light will be focused on the screen. The light will pass through the lens of the projector.
As soon as the light hits the lens, it will be focused on the screen. There are three things that can cause you to get a blurry image.
The first is if you have placed the projector’s lens on a piece of paper. If the paper is too small, it will not focus the light properly.
Build a Support for the Lens
Your lens has a rectangular frame. This makes your lens look rectangular. If you want your lens to look round, you can create a support for it.
To make the support, cut a strip of black paper that is long enough to go around the edges of the rectangle. You can put this black paper inside the frame.
Place the Mirror
If you want to take a picture with your phone, you need to place your phone at the bottom of the frame. This will be the top half of your image. The bottom half of the image will be the bottom half of the frame. To fix this problem, you need to place your phone upside down, but not directly onto the mirror.
Cut Out the Lid
When you take out your phone, make sure that you turn the backside up before you start using it.
You can do this by removing the back cover of your phone. You can use a knife to make the hole if you want. After you cut out the hole, use tape to close the back cover.
If you are going to give something as a gift to someone else, you should spend some time making it look nice.
It doesn’t matter whether you are giving it to a friend or a family member. You may need to put in some finishing touches.

Here are some common questions people ask when making a homemade projector with a mirror.
How do I know what size mirror to use?
You can use any size mirror you like, but you will have to adjust the distance between the mirror and the screen.
How far apart should the mirrors be?
The distance between the mirrors should be equal to the width of the screen.
How do I project the image?
You will need to take the batteries out of the flashlight, put them in the lampshade, and put the lampshade on top of the battery.
How can I make sure the projector is working?
You will need to turn the projector on and see if it’s working.
How long will this last?
This depends on how much power you use, but a good projector will last for year.
How do you make a homemade projector without a magnifying glass?
You just need some very basic tools like a small flashlight, a strong magnifying glass, a pair of scissors, some masking tape and a sharp pencil.
How can I project a picture on a wall without a projector?
You can use a TV as a projector. With this method you can project a picture on a wall up to 10 feet high. You will need a remote control for your TV. To use the TV as a projector, you have to set it for projection mode (as shown below). In projection mode, the picture is projected on the wall.
In conclusion, In this post, we teach you how to make a homemade projector with a mirror. This project is very simple project. You can easily make it with the materials that you already have at home.
