Also, ensure that the cardboard or shoebox you’re using is big enough to change the size and distance of the visual projection.

The bulb is also an important component, so it’s essential that you use a bulb that fits well. According to experts, the SYLVANIA LED bulb is the best as it is designed to function perfectly with any kind of energy and it’s not expensive.

You’ll need a pencil to make marks as you will have to make some cutting. It’s best that you isolate the area you’ll be cutting beforehand.

Amongst the needed materials is a razor or X-Actor knife. These two pieces of equipment are sharp objects, so it’s essential that you’re careful while handling them. It’s advisable that you don’t let your kids go near them.

The water you’ll make use of must be free from impurities. You are to pour water into the bulb until it is full.

You will need your smartphone to play whatever movies you want to watch. The screen of the smartphone is small and can’t give you the feel of a cinema, hence you’ll need the projector to give you a wider view.

The phone stand is needed to support the phone and prevent it from falling when you put it into the cardboard or shoebox.

Any tape or glue you use will serve perfectly well. It will be used to hold together every attachment that will be made when constructing your projector.

Step 2: Set the Bulb

Now, set the glass part of the bulb into the center of the cardboard or shoebox (anyone you are using) side. When you’ve got the bulb at the right spot, use a pencil to make a flawless mark around the spot as you will be cutting it away.

Step 3: Put the Bulb in Position

How to Make a Projector Without a Magnifying Glass in 6 StepsAfter flawlessly making a mark on the right spot of your cardboard or shoebox, you will pick your razor or X-Acto knife and cut the area off. You’ll then insert the bulb.

While cutting the section of the cardboard or shoebox off, be cautious not to extend the cut more than the area you marked. If you know that you have a shaky hand, you can call for help from a family member or neighbor.

After fitting the bulb perfectly, use your tape or glue to make it stick to the cardboard or shoebox (anyone you are using). Wait for approximately five minutes to make the bulb stick properly.

Another option you have is to place your phone upside-down within the box.

After you’ve rotated the video correctly, perform a test run to see if it’s projecting high quality images. If it’s not, adjust the projector by moving your smartphone forward and backward till you get a high image quality.
