🎥 How to make your own hands projector at home: ways for beginners

The operating principle of a film projector: the scheme and the device

If there is an old broken appliance is extremely simple to understand in his scheme in his arms. Suffice it to disassemble and examine all the components parts. If this is not possible, consider a simple device in the photo. The main condition for the organization of the home cinema screen - is the presence of high-precision components.

Thus, a professional projector scheme based on the following details:

• light to transmit through (any source can be selected, even high-power LED);
• condenser lens;
• a color wheel or a matrix (for modern devices);
• aspherical lens;
• DLP-chip;
• lens;
• screen (often used for such purposes multimedia boards).

Focused light bulbs, and high-quality matrix (this can be taken from any phone or tablet) collectively supplied image enlarged through a lens to the screen, mounted on a wall. As such, can act white sheets, oilcloth, and even a light background of furniture or wallpaper.

The image quality achieved lenses and lamp luminance. Therefore it is necessary to select the source with high efficiency. Furthermore, it is necessary to correlate the size of the screen and the light output radiation. Simply put, the further from the light source to the projection, the stronger the light bulb must be taken.

Production of the projector with your hands on your phone based on

Modern gadgets often have solid expansion, through which you can get high-quality broadcast video. They can watch any movies on the Internet, as well as self-shot video. We consider in detail the steps for manufacturing such a device.

The simplest projector

To make a simple device, you will need a minimum of parts. But count on the full quality of the image in this case is not necessary, since most smartphones are not able to transmit the image to a sufficient brightness over a long distance. Nevertheless, it is an excellent alternative if the projector at all.

What will it take to work

Projector devices require a cardboard or wooden box and a cardboard casing smaller size in which you want to make a niche for a smartphone. To the walls of the box is less reflected light, it is necessary to paint it black. For this ideal shoe polish or matte paint. You will also need a lens.

Prepare all the elements

The sequence of operations is as follows.

1. Properly Equips the box. To do this, the inside of the hull paint the darker color.
2. We put in it a box of smaller size so that the prepared niche, which is inserted into the smart phone was the size of the screen.
3. Direct opening on the free edge of the second box.
4. Preparing a suspension or stand for the lens, set it on the table, attach it to the enlarger.
5. It may be fixed to the cardboard box, pre-cut for this special niche.
6. To enlarger did not fall, it is fixed by a glue gun.

construction assembly

When all the details are arranged, remains bring them together. Insert the included smart phone into a prepared niche and direct the image through the lens onto the canvas, set as a screen.

This projector is useful if there is a remote control, which works on Wi-fi, different for each switch will have to retrieve the phone out of the box.

The manufacturing process of the holographic projector

Holographic projectors are able to accurately convey the picture from any mobile gadget, subject to the inclusion of maximum brightness. Details can be found in his workshop or a little to spend on the purchase in the store a few bets.

The list of materials and tools

To quickly create 3D-projector will be useful:

• body from CD-ROM drive;
• glue gun;
• paint or stationery knife;
• pliers;
• smartphone;
• special holographic video graphics;
• the corresponding drawing.

It is important to comply with all the dimensions of which are registered in the drawing, otherwise it will be impossible to achieve image sharpness.

Fabrication details for the projector

To create a truncated pyramid, use the drawing, which will calculate the size of each part.

Consider the step by step algorithm:

1. With the help of the drawing, we note four similar sketch on the plastic case of the disc, and using stationery knife, carefully cut out of them.
2. All these parts are glued together glue gun so as to obtain a truncated pyramid.
3. When the ends chipping patterns, they are treated with sandpaper.
4. Set smartphone upper part of the pyramid so that the display is centered.
5. We place on top of a dark or matte cardboard (to animation is not otzerkalivalas).

Similarly, one can use the projector in a vertical position. But for this it will be necessary to make a stand holding the smartphone and matte board.

Adjusting the image on your smartphone

So that the image displayed on the high-grade matte surface, it is necessary to perform some settings screen. Be sure to set the brightness to the maximum level, adjust the color, so that it was natural. In this situation it is advisable to install an automatic contrast mode, and the background color to "Standard".

Projector with his hands on the base plate

All modern tablets have a mass of possibilities, so you can browse through them, and movies, and favorite videos on the big screen. The likelihood that the image will be distorted, reduced to a minimum, as the screen options allow you to transmit the image quality.

I need to work

In order to prepare a simple home theater with his own hands, you must have:

• two cardboard boxes of different sizes;
• stationery knife;
• lens with a good focus;
• the tablet;
• PVA or glue pistol;
• black paint.

Production of structural elements and steps

To properly make a video projector with your own hands, it is advisable to act according to the instructions below.

GOOD TO KNOW! (Click to see)

The projector of the device for viewing slides

Using ordinary magnifying glass is justified for the manufacture of projectors for amateur movie viewing. But the picture was truly quality, you can use a special slider, which is used in schools. Such a slide projector easily created. To use it, just need to find a good source of playback images.

List of materials to work

The user only concern - and setting the correct setting is almost ready projector. That is useful for this purpose:

• factory matrix with pre-configured optical nodes;
• projector factory;
• laptop or tablet, from which extracted the matrix;

stages of work

We must try to disassemble a laptop or tablet so that its screen was not injured. Further, the construction is simply placed in a slide projector and start a slide show or video. In this situation, the screen acts as a navigator on the tablet system. How it looks in practice.

1. We connect the matrix to the inserted plate and find the device to control. This can be a special Wi-Fi- Wireless Module, or an ordinary computer mouse.
2. We turn on the projector in the network and sends it to the lens on the multimedia screen. In a special professional board may act as him.
3. Play video and watch it as much darkened room.

In order to obtain maximum image quality of the projector is set special gobo lens.

Useful tips craftsmen and fine manufacturing

When you create a projector every thought about his future destination. It is from this factor is a start when choosing the size of the multimedia device. Learn a few useful recommendations from users.

1. If you plan to frequently watch movies in the twilight, and do it with the whole family, you do not need a movie theater. The only condition is to use no more tablet or phone, and construction pogabaritnee alternatively laptop.
2. better use of materials worthy quality, such as plywood, MDF or for the manufacture of the projector. Be sure to take care that the device has turned out to be stable.
3. If you want to stream video on a screen placed high, it is better to provide for the availability of the stand immediately. Do not attempt to enclose the device under books or other items. Necessary to observe the angular radiation.
4. The most spectacular view is only at night in the absence of artificial illumination.
