It is best to watch videos and movies on the big screen, as in a real movie theater - this requires a projector and screen, all this is very expensive, and not every family can afford it. But there is a way out - you can design a projector with your own hands at home, and then invite everyone to the first viewing. According to competent experts, such a miracle of homemade technology is almost not inferior to the standard product. There are several manufacturing options - they are all similar, because each uses a special lens and cardboard boxes of different sizes.

Based on a mobile device

Projector out of the box, phone oriented, belongs to the category of home crafts, which are easy to do yourself. To make it clear to every reader, how to make a projector from a phone, we present a step-by-step manufacturing algorithm, accompanying photos of the process. To make a homemade video projector, you will need the simplest set of tools, consisting of an old box of shoes, dandruff with 10-fold magnification, sharp knife, marking pencil, insulating tape and smartphone.

Use a standard magnifying glass or Fresnel lens as a magnifying glass, which can be purchased at any home improvement store.

  1. Carefully cut out the window for the lens, Determining the center at the end of the box is a very important step, because the dandruff should be strictly in the center.
  2. Now you need to fix the lens in the hole made - you will need insulating tape, but other options can be used for reliability and aesthetic perception: silicone or strong glue.
  3. When making a projector from a smartphone, then the main task is to properly install a stand of solid cardboard for the phone. The transmitting device must be located in a certain place in the box, fasten rigidly, so that the image on the screen does not flicker.
  4. The curtains should be closed in the room, turn off all light sources, and in the dark to do testing - to determine the desired location of the device, to make the image on the screen clear.
  5. Now you need to install a special application on your smartphone, which will flip the image, T. TO. The lens when designing expands the image on 1800. It's easy to do - in the search bar type "application for rotating the screen on a smartphone" and choose any to your liking.
  6. Now no less important point - you need to make a small hole at the bottom of the back of the lens, to connect a smartphone charger.

The homemade projector for home theater is ready, now check its operation, determine a specific location and invite family members to watch videos. There is an excellent video to help the masters.

Based on a tablet or laptop

If you decide to make a projector for the house with your own hands and want to achieve a better image, then you should use a tablet as a transmitting monitor - the screen resolution is much higher, than a smartphone, so, and the quality of the transmitted image is much better.

The laptop has these parameters even better, but the projector itself will be cumbersome - you have to choose, given the size of the room for showing movies.

Box, to build a home device based on a tablet, choose a larger size: its length must be at least 50 cm, and the end side is slightly larger than the tablet screen. To increase it is better to buy a large magnifying glass of Soviet production, then the quality will be excellent. An example is the device for full-page reading of books, the cost of the lens will be within 8 dollars.

Cut a hole in the end with a knife, which will be slightly less dandruff, then fasten the lens with double-sided adhesive tape, corrugated surface inside the box.

Fix the tablet inside the box, given this, that the lens inverts the image.

Laptop-based design is slightly different - rectangular holes are cut on both sides of the long end of the box. The device itself is located monitor down, and the keyboard on top of the cardboard base - it helps to get the right image, rather than an inverted version.

How to improve image quality

To increase the quality of the final image, you need to set the maximum settings on the product monitor, from which the broadcast is carried out, to exclude penetration of light into the room, where the review is organized. The distance to the screen also affects the quality: the closer the homemade projector, the better the quality, but less picture.

All these parameters are easy to adjust in advance and achieve this quality, which will completely satisfy you. To the screen, on which the picture is projected, there are separate requirements: the canvas must be of high quality, without seams and defects.

Importantly! If you paint the inside of the box black, eliminate the "leakage" of light flux through the slits, then the picture quality on the screen will improve significantly.

original solutions

Similar to a smartphone-based device, you can make a home 3D projector with your own hands or construct from improvised means, example, CD boxes, homemade laser projector for displaying holograms, only these options are more time consuming, and costs will be from 8 to 15 non-taxable minimum incomes.

A special size pyramid made of plastic is required for a 3D device, the size of which can be found on Internet sites. Example, such an option: height 45 mm, entrance truncated hole - a small square 10x10 mm, and the lower part - 60x60 mm. Then we place this original design on the smartphone exactly in the center of the screen and include a pre-selected video.

Before, how to make a projector with your own hands, it is necessary to clearly define the purpose of its use, the chosen type of construction will depend on it.
