View videos and images on your homeprojector - this 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 for them is not affordable for everyone. But is there a way out of this situation?
For this device you will need a largemagnifying glass and a box. The first element (lens) will be used as an objective for our projector. Such a device can play and display photo and video files even from a mobile phone. This distortion of data and sound will be minimal.
So, how to make a projector with your own hands fromshoe box? 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. By these actions, you will significantly improve the quality of the video being played.
How to make a projector with your own hands further? At 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 screen must necessarily be directed "face" to the lens. To the mobile phone does not accidentally shift to the side, it is better to use a special stand or holder (for example, car on suckers). Thus, we made the projector with our own hands from the phone and a cardboard box from under the shoes.
It's very simple - the image from a mobile phone is projected through a magnifying glass on the wall. You will be able to increase the screen in dozens of times, while maintaining the true quality of the images.
Finally, we note a few nuances in the installationmobile 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 cellphone back of the box, thereby adjusting the desired focus.
Similarly to the first case here we needmake a small hole. To make it in the central part of the box by the diameter was several centimeters smaller than the largest lens, it is necessary to delineate its attachment point 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.
If you are using the data sourcetablet, then to fix it you just need to prepare several thick books or a stable box that has the 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.
And finally a few words about the brightness. We adjust it 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.
