How to make Projector at Home (3 Easy Steps)

While we can watch our favorite shows and movies on our phones, they can't compare to the magic of a big screen.

The enormous screen is a significant part of what makes going to the movies so enjoyable.

These massive screens allow filmmakers to leave not only long-lasting memories on their audiences but also to delight them with larger-than-life sights.

What is Projection?

Projection is an ancient technology that Plato, the Greek philosopher, first mentioned. The core technology behind any type/form of projection is the straightforward concept of shadows. Projection, like shadows, requires a light source. When you place an image in front of a light source, the object appears as a shadowy picture on the wall(screen) in front of you.

Types of Projection

● The light source is behind the spectator, and the screen is in front in front projection. It is valid in all movie theatres.

● The light source and the screen are kept in front with a back projection, but the light is behind the screen.

How can you build a projector for yourself?

You'll need:

• A shoebox
• Magnifying glass
• Cello tape
• Cardboard sheets
• Cutter
• Marker/pencil
• Double-sided tape
• Glue
• Protractor (optional)
• Acrylic paint (optional)
• Brush (optional)

Method:

1. Take the magnifying glass from its holder and set it aside.

Place this glass in the center of one of the shoe box's sides (as seen in the picture) and trace around it with the marker on the shoe box.

2. Set aside the magnifying glass. Cleanly cut out the part marked in step one with the cutter.

You can use a protractor to aid you with this but going hands-free is also an option.

You now have a cavity on one of the shoe box's sides, precisely fitting the magnifying glass.

3. If your magnifying glass is somewhat more significant than the height of your shoebox, you'll also need to cut a semi-circular cavity in the lid to fit the lens 

4. Take the magnifying glass and place it into the cavity. It may be done using either glue or duct tape, or both!

5. Now is the time to paint your projector if you want to.

Color the outside of the box however you wish; it can be completely black or all white, or it can have a bright design pattern.

Paint the box any way you like and set it aside to let the paint dry.

6. Let us now take a stand for the cell phone. To determine the width and length of the sheet that has to be cut, measure the space within the shoe box.

Cut two equal pieces of cardboard according to this size.

The standard measurement is 17 cm x 10 cm.

7. Place the two cardboard sheets perpendicular to each other, with the standing board's longer edge running through the middle of the bottom board.

Apply the glue to the bottom border of the standing board and press it into place until it is secure.

To make your stand stay stable, add extra glue to both sides of where the two boards connect.

8. Apply the double-sided duct tape to the back of your phone and press it against the phone stand, ensuring that it sticks and stays in place.

9. Place the phone stand behind the magnifying lens inside the shoe box.

10. Place the shoe box against a clean, white wall.

11. Set your phone's brightness to maximum and then slowly move the phone stand closer to the lens to calibrate the position of the phone stand inside the shoe box. Take note of how the image becomes sharper or softer. Adjust it till the image is as sharp as possible.

13. Replace the lid on the box and turn off the lights in the room, and your homemade projector is ready to shine!

Keep in mind that the image created is frequently reversed, although the brain compensates for this. That's precisely what's going on here as well!
