How to make a projector by yourself at home?

Viewing videos and images on a home projector is a very exciting and interesting event. After all, you will always have the opportunity to invite your friends and watch a feature film on a large screen together. Moreover, with the development of technology, new digital projectors began to appear in stores. However, the cost is not available to everyone. But is there a way out of this situation? It turns out there is. How to make a projector yourself, read in our today's article.

How to make a device from a conventional shoebox? Preparation of materials

For this device you will need a large magnifying glass and a box. The first element (lens) will be used as an objective for our projector. Such a device can play and display photos and video files even from a mobile phone. This distortion of data and sound will be minimal.

Getting Started

So, how to make a projector with your own hands from a shoebox? First you need to paint the inner walls of the tank black. If you did not have such a paint on hand, you can paste the box with black paper. With these actions, you will significantly improve the quality of the video being played.

How to make the projector yourself? In the next step, on one of the upper parts of the box, cut a small hole to install the magnifying glass. The latter is fixed by means of an adhesive tape or an insulating tape. However, you need to be extremely careful - there should be no light around the lens, otherwise the projector for the house, made with your own hands, will not show the image quality.

Inside the box there is a telephone. The gadget's screen must necessarily be pointed "face" to the lens. To the mobile phone does not accidentally move aside, it is better to use a special stand or holder (for example, the car on the suckers). Thus, we made the projector with our own hands from the phone and a cardboard box from under the shoes.

How will the files play?

It's very simple - the image from a mobile phone is projected through a magnifying glass on the wall. You will be able to zoom the screen dozens of times, while maintaining the true quality of the images.

Finally, we note a few nuances for installing a mobile phone. From the lessons of physics, we know that the image passing through the magnifying glass turns out to be inverted. In this regard, the phone in the box should be rotated 180 degrees. And to adjust the clarity of the image it is enough to move the screen of the mobile phone back of the box, thereby adjusting the desired focus.

We make the projector with our own hands out of the box - method # 2

Similar to the first case here, we need to make a small hole. To make it in the central part of the box by the diameter was a few centimeters less than the largest lens, it is necessary to outline its mounting location in advance. For this, a lens is applied from the outside of the container, and a rectangle is drawn on it using a marker or a soft pencil. Inside the resulting image, another figure is drawn, but here it is necessary to retreat a couple of centimeters inwards. By the way, the rectangle can be drawn on the contours of the bank card. The lens is securely attached to the front of the box. Here it is necessary to take into account that the corrugated part of the magnifying lens should be placed by the end part inside the container. After fixing the magnifier, the box folds and closes. Appearance of such a projector is unlikely to anyone like it, so after its final assembly it is recommended to paint it with a dark paint from the can.

How is the image source in the box fixed?

If you use a tablet as a data source, then to fix it, you just need to prepare several thick books or a stable box that has dimensions equal to the dimensions of the gadget. To fix the device in an inverted state (for correct display of information), thin bands are additionally used. If the source of the image was a laptop, then in this case neither thick books nor a box will help to keep it in this state. Therefore, to fix such a computer in the back wall of the box, another hole is cut out. Its dimensions should correspond to the length and width of the laptop display. Then the computer turns 180 degrees and puts the keyboard up on the cover of the box. It is best that the walls of the projector are not cardboard, but at least plywood.

And finally a few words about the brightness. We set it up to the maximum so that the image is displayed as clearly and qualitatively as possible. So, we figured out how to make the projector with our own hands and how to properly insist the sources of the image in the box.
