The simplest laser show on your own. Do-it-yourself laser spirograph Organic glass color music

Here is the design of the simplest installation for a laser show that anyone can make.
Moreover, this installation does not even require knowledge of electronics - we only need a laser pointer, the most ordinary CD-ROM and a speaker.

The principle of operation of this device is extremely simple: we connect a speaker to the output of the amplifier. This speaker must be fixed with the diffuser up. It is better, of course, to use speakers - there the speaker is already fixed inside the case and it will be enough just to put the speaker on some surface.

A piece of plastic pipe with a diameter of 25 ... 30 mm is attached to the speaker cone with glue. A pipe can be used, for example, a water pipe - they are freely sold at any hardware or hardware store.

Device assembly order:

Step 1. We take and cut off about 20 centimeters from the water pipe. Carefully clean the edges and set aside.

Step 2. We take an unusable laser disc and cut out a circle from our laser disc, 4 mm in diameter. less than the inner diameter of our pipe.

Step 3. Cut out a circle with a diameter larger than the diameter of the pipe by 4 cm from a balloon or a medical rubber glove. We stretch a circle of rubber on one edge of the pipe and fix it with a strong thread.

Step 4. Now carefully glue the circle from the laser disc in the center of the stretched rubber on the pipe. As a final result, we should get the following design: a 20 cm pipe. At one end, thin rubber is stretched, fixed on the side with a strong thread, a circle of a laser disc is glued to the rubber in the center. The laser disc circle is glued with the reflective side facing out.

An example device drawing would look like this:

Here:
a - top view (enlarged); b - side view;

1 - pipe; 2 - rubber membrane; 3 - a circle from a laser disc; 4 - laser pointer; 5 - trajectory of the laser beam from the laser pointer to the wall; 6 - speaker or column; 7 - wall.

The last step is setting up the installation. We take the speaker and connect to the output of the sound source. It can be an amplifier, computer speakers, an output of a music center or a tape recorder. You can take the speaker and put the speaker up. We put our home-made laser installation in the center of the speaker with the laser circle up.

Turn on the music and make sure that our laser machine stood firm and did not fall. Now it remains to direct the laser from the laser pointer to the circle from the laser disk at a certain angle. The laser bouncing off the laser disc should hit the wall. And lo and behold, intricate figures are drawn on the wall. Depending on the melody being played, the pattern reproduced by our homemade laser machine will change.

Now you need to fix the laser pointer so that the beam hits the surface of the laser disk at the right angle. To achieve a more spectacular laser show, multiple lasers can be used. Also, on the path of the laser beam reflected from the surface of the laser disk, you can put a smoke screen, for example, from church incense. The laser beams, passing through the smoke, will create three-dimensional figures.

The principle of operation is as follows, sound waves act on a rubber membrane with a circle of a laser disk fixed on it. As a result, the mirror surface of the laser disk trembles and changes the angle of reflection of the laser directed from the laser pointer. The laser beam forms intricate shapes on the wall. The added smoke, in the path of the reflected laser beam, makes it visible.

The second version of the laser show

There is also nothing complicated here: we need a laser pointer and a couple of fans from the computer (coolers).
A piece from a laser disc or a thin mirror is glued to the fans strictly in the center. It is necessary to glue in the center so as not to disturb the centering of the blades.
In order to increase the scattering effect of the laser, one side of the mirror needs to be slightly raised. We attach the entire structure to plywood, plank or to a piece of laminate or MDF.

The relative position of the fans can be adjusted to your liking - just look at the resulting picture.

Laser color music

Laser color music in a car is a novelty that has become especially popular among young people recently. And although such an innovation costs a lot, it has already been acquired by thousands of users around the world.
It is something like a ball used in clubs. However, in this case it has a rectangular shape and, if necessary, is located on a tripod.
Knowing what a scheme of laser color music is, you can try to make it yourself.

Device Features

The MiniLaserLight is a small device that looks like a projector.
With it, you can:

  • Create a real laser show in the car;
  • Due to the fact that the device moves, it can be taken out into the fresh air and organize a dance floor.

Currently, there are several varieties of the device. They all work on the same principle.
In addition, they are united by almost the same characteristics and control. The only difference is what kind of projections the laser can create. The device starts working from the car cigarette lighter.

The projector has the following features:

  • Can work in strobe mode;
  • The user can independently adjust the flickering speed, as well as the speed of changing projections;
  • Inside the device there is an active microphone, as a result of which it works in time with the music.

You can install it not only in the passenger compartment of the car, but also in the luggage compartment. In addition, the installation of the device can be performed in any other place in the car.
Before that, you need to fix the color music (see) on a special tripod included in the kit. Particular attention should be paid to installation.
It is impossible that the beams emitted by the laser interfere with the driver during the journey. The beams cover a large area, you just need to install a high-quality model of laser color music for this.

Other types of color music

As noted earlier, laser color music costs a lot, so not everyone has enough money to buy it. You can create it with your own hands.
To do this, it is enough to use an ordinary garland (see). Before starting work, it is recommended to carefully study the color music scheme so that there is no short circuit in the system.
Its main provisions are as follows:

  • The main input is required for the wires that turn on the amplifier. The device is connected like this: one of the wires from the speaker is removed, and a wire for color music is installed in its place.

Note: installation can take place in parallel, while everything remains in place. If you make this connection, the lights will flash at the same time as music is playing.

  • Light bulbs are connected through special thyristors. They are equipped with control electrodes that receive voltage through filters on capacitors;
  • In order for none of the elements to burn out, it is recommended to rectify the voltage to the nominal voltage using diodes. The latter, in turn, are responsible for converting alternating voltage into pulsating, and vice versa;
  • Thyristors should be placed in metal cases. The anode is brought out through the body, and the cathode is placed on top. Their fixation is carried out with nuts directly on the board.

Color music from a garland

The garland is great for creating high-quality color music. They are collected in one pile, after which they are glued together with electrical tape in several places. You should get a skein that resembles a ball for color music.
If it was decided to use a garland for this purpose, then it is recommended to buy a special adapter designed to connect the light bulb and the car radio.
The operation is carried out according to the following algorithm:

  • Take several New Year's garlands 1-2 meters long;
  • Buy a special adapter;
  • Prepare ;
  • We connect the garland to the head unit using all the necessary wires and an adapter;
  • Turn on the radio, then go to its main menu. Select the "flash" zone, which is responsible for the work of color music;

Note: if you have access to the Internet, you can download one of the computer programs, with which it will be much easier to install and configure color music.

Organic glass color music

Another, no less interesting view is color music made of plexiglass.
To do this, you may need the following materials:

  • Adapter;
  • Headphone cord;
  • Transistor;
  • Organic glass;
  • LEDs;
  • Cable.

The algorithm for performing actions is as follows:

  • First of all, you need to make a box for color music. To make it easier to do this, you can draw his diagram on paper;
  • Transfer the created pattern to the plexiglass, after which - cut out all the details with a knife;
  • 2 holes should be drilled in one of the walls: one for headphones, the other for powering the device;
  • Using a fine skin, plexiglass should be matted;
  • Do the same with LED lenses;
  • Assemble the body. All elements can be fastened with glue. To facilitate the work, it is recommended to use a glue gun.

Make laser light music

Everyone can assemble color music according to this algorithm, since this process is very simple, but at the same time effective.
Everything is done like this:

  • Divide the LEDs in half;

Note: they can be purchased at the store, but it's easier to remove them from a regular flashlight.

  • Find a small box in which color music will be installed;
  • Install a switch on it that changes the mode to normal lighting;
  • Three AA batteries can be used as a power source;
  • After that, it can be placed anywhere (not necessarily only in the car).

In the process of creating color music with your own hands, it is recommended to study thematic photos, watch videos on this topic. The instruction will also not be superfluous. It is still better to give preference to a homemade device, since its price in stores is very high.

You can rightfully compete with Pink Floyd - now you will have the opportunity to arrange your own laser shows! The value of this laser spirograph is difficult to overestimate, despite the fact that it is quite easy to assemble.
The spectacle of spiral patterns that are reproduced on the surface of the walls with this small box is fascinating and attracts attention more than they deserve. Most of the people I showed the spirograph patterns to were willing to dance all day long for free. And I can only imagine what your cat would say! However, there is only one way to find out - you need to collect this device.

Let's collect the materials we need:
- Plastic jars for paint (for example, gouache) (4pcs)
- Round mirrors with a diameter of 2.5cm (3pcs)
- Gear motors 1.5-3V (3pcs)
- Potentiometers 25Ohm 3W (3pcs)
- Pen laser pointer
- DPDT toggle switch
- Lockable battery compartment for two AA batteries
- Battery compartment for two AAA batteries
- Control handles (3pcs)
- AA batteries
- AAA batteries
- Short cable ties

Let's start marking on the lids of the paint containers. Place the electric motor on the lid of the jar and make two marks on each side of it as shown in the image. Repeat the same with the remaining pairs of motors and jars.

Now you need to drill holes in place of all those marks that you just made. To do this, use a 3mm drill.




After passing the clamps through the holes drilled in the previous step, firmly fix the motors on the lids from the paint containers so that the gears mounted on their shafts are outside the lids.

Glue the mirrors to the gears with a glue gun. Try to glue the gears to the center of the mirror, but don't worry if you can't achieve perfect accuracy. It is these minor flaws that will subsequently help to obtain unique spirographic images.

Solder the red wires to the "positive" terminals of the motors, and the black wires to the "negative" terminals.

At the bottom of the case, put the jars with the motors fixed on them on the glue so that two are parallel at a short distance from each other, and the third is turned in the other direction and is located on the line passing between them. The laser will bounce off them in a zigzag pattern. In this case, the entire system is located in the housing at a slight angle.

Let's disassemble the laser pointer. Use pliers for this. Gently twist and loosen the metal head with the diode laser in order to remove it, together with the board, from the plastic case.

Cut about 15cm of the red cable. Remove 2-3cm of insulation and wrap around the golden ring on the laser head and solder them together securely. Carefully solder a piece of black cable (also 15cm long) to the right pin (assuming the SMT transistors are facing you) on the side of the board that is opposite the one where the switch button to control the laser is located.

Solder 15cm lengths of red wire to the right pins of the potentiometers. Solder the red wires from the motors to the center pins of the potentiometers. Motors are connected to potentiometers in pairs.

Solder the red wire from one of the battery compartments to one of the center pins on the toggle switch. Solder the red wire from the other compartment to the second center pin. Then solder the three red wires coming from the potentiometers to the outer pin adjacent to the pin to which the red wire from the AA battery compartment is soldered. Finally, solder the red wire from the laser to the pin next to the three soldered wires from the potentiometers.

Solder the black wire coming from the laser to the black wire of the AAA battery box. Solder the black wires from the motors to the black wire of the AA battery compartment.

Cut a 5cm x 5cm section into the body wall at the point where you expect the laser beam to pass through the last mirror.

From one edge of the housing cover, make three marks on the same line (distances from the edge - 3.5cm, 6.5cm, 9.5cm). In place of these marks, drill holes with a 9.5mm drill bit. Next to them (at a distance of 5mm to the left of each) make other holes with a diameter of 3mm for attaching a potentiometer. This way we will fix it so that it will fit snugly on the lid, and will not rotate after installation.

Insert the potentiometers into their pre-drilled sockets (9.5mm diameter) and secure them securely in place with the mounting nut.

Insert the batteries into the battery compartments. Now you should check if the toggle switch is working, turning the entire circuit on and off.

Drill a hole in the case with a diameter of 6mm on the side where the potentiometers will be placed. Ideally, it should be opposite the section cut into the body wall. Install a toggle switch in this hole.

Glue the LED laser onto the lid of the last remaining paint container. Inside the case, empirically select for it such a position that the beam is reflected from all three mirrors and exits through the previously sawn section. After finding the right position, glue the jar to the bottom of the case.

Place your palm or piece of paper in front of the beam hole in the housing wall. Rotate the motors and the laser to center the image. If the beam hits the walls of the housing, you may need to widen the hole.

Gather the wires in bundles and tie them together so that when the lid is closed, they do not interfere with the rotation of the motors and do not block the laser beam. Attach the battery compartments to the inside of the case as well.

Place the cover on the chassis and secure it in place with the mounting screws.

Install the control knobs on the potentiometers.


That's it - now you have a laser spirograph that you have assembled with your own hands! You can call your friends and have a party - it will be a success!

Homemade laser machine

Technicians have always paid careful attention to laser devices. Today, many people are interested in making a good laser with their own hands in order to use it for its intended purpose. From the article you will learn how to make laser color music (laser soundlights).

Benefits of using

If you dream of surprising your guests, then organizing a gathering of friends at your place, prepare a surprise from laser color music of an unusual shape. Images that will be thrown by a powerful laser on the ceiling and walls are always an unusual and bewitching sight.

A party with original and beautiful drawings will leave indelible impressions in the memory of friends, and the photos taken in the process will delight for a very long time.

It is extremely interesting that for the first time laser soundlights were mentioned in the middle of the last century. Today, such an installation is a compact device with the widest possible adjustments and numerous options.

Note. A laser device, including home-made options, belongs to the category of art. With their help, you can create an enchanting and picturesque show.

It will be useful to know that laser soundlights is divided into several styles:

  1. laser graphics. This style focuses more on creating colorful images and shapes on the surfaces of the room. The figures move in time with the music, it turns out very beautifully and synchronously.
  2. Full laser show. This style is already moving in space with changing patterns. It is advised to use this performance in large halls or on the street.
  3. Combined show. Figures from graphics and spatial rays are mixed. It turns out the most spectacular show.

You can buy a laser installation today, since there are no restrictions on choosing a model. It is, however, a little expensive, but you can always assemble laser soundlights on your own, if you have the desire and brains working in the technical direction.

Simple instructions for creating color music

To make such color music is within the power of everyone. It will take little time, you don’t need to buy anything, since the basic materials can be prepared from improvised means.

  • 20 cm metal piece.
  • CD or DVD CD and laser pointer.
  • A piece of flexible rubber.
  • Clay Moment.
  • Insulating tape.
  • Speaker playing music.

Begin:

  • We remove all burrs from the pipe, make it smooth.
  • We cut out a circle from the disk, the diameter of which is 4-5 mm smaller than the diameter of the pipe.
  • We cut out a finger from a rubber glove, which can later be put on the pipe.

Note. The rubber must be pulled over the end of the pipe, and tightened well with electrical tape.

  • Now the cut disk circle is glued by Moment to the end of the tube with stretched rubber. The circle should sit in the middle of the pipe, with the mirror side up.
  • The resulting installation is placed on top of the speaker, its grid.

It is recommended to fix the setting on the loudspeaker with something. We check the operation of the installation: we launch a beam with a Chinese pointer onto the disk. Light is reflected. It remains only to fix the laser pointer over the CD so that the beam shines as required, that's all.

When sound pours from the loudspeaker, the waves will cause the rubber and disk to vibrate. In turn, the vibrations will lead to the drawing of various figures on the surfaces of the walls or ceiling in the rhythm of the melody. It is effective to install an additional laser pointer, or even several, above the CD. And if you still blow smoke from the smoke generator, then the rays will pass through the smoke, leaving three-dimensional images.

Powerful laser

Of course, we will talk about the manufacture of not weak Chinese samples, popular among children. No, it will be a powerful 300 mW laser. For this reason, one must be extremely careful, as the beam can harm the health of people and animals. It is obligatory to put on protective gear, and in no case should the beam be directed at anyone or anything.

Any production begins with the preparation of certain components. This guide is no exception.

Here's what to prepare:

  • DVD drive with a recording speed of 16x or higher.
  • Various capacitors for 100pf and 100mf.
  • Batteries.
  • Chinese laser.
  • Lantern with steel LEDs.

Thus, it will be easy to make a simple driver from these components. In other words, it will be an ordinary board that brings the laser diode to the required power.

The Chinese laser is, in fact, a collimator or a module equipped with a lens. The latter transforms energy into a thin beam. Lazer-pointers or collimators made in China can be easily obtained from radio shops. They have a convenient place for the introduction of a laser diode. Devices cost no more than 300 rubles.

Note. In principle, the collimator can also be removed from Chinese laser pointers, but the diode will be more difficult to mount. And besides this, the body of the laser pointer collimator is always metallized, which will affect the worst cooling of the diode and the corresponding problems.

Let's move on to making:

  • We take out the laser diode from the DVD drive. Remember that the part is very fragile and small, it can be easily damaged. We act very carefully, removing the red diode from the drive carriage.

Note. It is necessary to remove a powerful diode, not a weak one. This is easy to determine if you pay attention to the size of the radiator. A powerful one has more than a conventional IR diode.

  • We wrap the ends of the zener diode with the thinnest hardware or use a special hold with an antistatic effect, since the laser is incredibly sensitive.
  • We solder the driver according to the classical scheme. We act very carefully so as not to confuse the polarity.

Note. If you mix opposites, the lazer diode will deteriorate almost immediately.

An interesting point. Before installing the zener diode into the circuit, assembling everything in a case, it is recommended to check the functionality of the driver.

It is also necessary to check the compatibility of the current and the diode. The ideal option is to put some other laser diode, it can be non-working, and then measure the current strength using a special meter. For 16x options, 300/350mA would be ideal. For 22 x it is possible and more - 500 mA.

A convenient case is not only for appearance, but also for convenience and functionality. Techies, as a rule, do not like to do this, they are not up to beauty, but since we are doing it for ourselves, we need to try. It is better to choose the initial scheme of the housing of the LED flashlight. Why? Everything is very simple: the dimensions are quite good - 10x4 cm, and the costs are small.

Everything, a powerful laser is ready - this is the most important thing. It hits surprisingly far, now you can create the most powerful color music, as in discos and clubs.

You can make homemade color music in other ways. The main thing is the desire to create something very original. Watch the video and photos, it will give a visual understanding. You can, of course, buy an installation, but the prices for really high-quality products are impressive in earnest.


Attention!!! Don't let it hit

laser radiation in the eyes - it's dangerous!!! A working installation

laser effects should be positioned so that the beam, under no circumstances

conditions could not get into anyone's eyes, as well as outside the premises

(e.g. through a window). It is also not allowed to use

laser effects (as well as other light-dynamic installations, including

strobe lights, flashing garlands, color music) in the presence of people,

suffering from epilepsy.

Thinking a lot about how to simplify the motor control circuit itself under the accompaniment of music, I decided not to use the circuit from "Simple 12V color music on LEDs" for this? Yes, it’s her, because there are the necessary low-pass, midrange and high-frequency filters there, but instead of LEDs, hang three motors into the load, and you need to replace the KT361 transistors with more powerful ones, for example KT814.

And here's the schematic:

This circuit behaves well when driving motors from old cassette recorders, only you need to desolder the speed stabilizers from them, because our motors must either accelerate or reduce their speed at the desired track at one time or another. Depending on the accompanying music, when the circuit is assembled and running, the beam from the laser that hits the mirrors of the three motors bounces off them and draws various figures (effects) on the wall.

In some cases, one or another effect can be observed in 3D format, because we use three instead of two motors and they spin at different speeds depending on the accompanying track.

With the possibility of using a third motor, the effects themselves are multiplied, for example, if two motors are used, then the number of effects is two-digit, if three is three-digit.


The polarization of the motors is selected experimentally, in order to obtain a larger number of drawn pictures. Also, for this, resistors R8 are adjusted. visual indication. Mirrors on motors should be selected as thin and light as possible so that they do not play the role of a flywheel, stop and pick up rotation speed in the desired time range. You need to glue them at an angle, as in previous versions.
