How to make color music from a Christmas tree garland. How to make color music using LEDs on your own

This simplest light music has only one element. Yes, absolutely alone and nothing but: no resistors, no transistors... It is quite possible to assemble such a light and music installation in 30 minutes. All you need is one solid state relay.
Solid-state relays appeared on the market relatively recently and have already confidently conquered the radio electronics market. It’s understandable, I’ll give you the main advantages.

• - Performance.
• - Galvanic voltage isolation.
• - Quiet compared to a conventional relay.
• - Zero crossing detector.

There are many more advantages, I have cited only a few.
A solid-state relay, in essence, apart from the name, has nothing in common with a mechanical relay, which everyone usually imagines when hearing this name for the first time. This is a regular triac switch, with control and decoupling circuits.
This miracle is quite inexpensive and can be easily bought on our favorite Aliexpress.com

There are many different versions of relays on the radio market: small and large, powerful and low-power. I took this:
Firstly, it has screw terminals for connection. Secondly, it can switch a load with a voltage of 24-380 V and a current of up to 60 A. Of course, I took it overkill for other purposes. To control the garland, it is enough to take from 2 A. Thirdly, control voltage from 3 to 32 volts, pulsed. Just what we need, since we will control the relay directly with the sound supplied from the output of the low-frequency amplifier.

Light and music circuit

A solid-state relay is connected to the open circuit of a lamp or garland. And the sound from the solid state relay is supplied to the input speaker. The scheme couldn't be simpler. The main thing is not to confuse the conclusions. Now, as soon as the music starts playing in the speaker, the garland will immediately start blinking in time with the music.
We take the output from the amplifier from any channel, left or right. You can connect between the outputs so that the garland flashes with a stereo effect. If there is a subwoofer output, you can connect it to it. Or you can take two garlands and two relays and connect to different channels. There are a lot of options, choose any one you like.

I added a park of toggle switches to the circuit for switching. The first toggle switch in the diagram so that you can simply turn on the garland normal mode. And the second is to turn off the influence of music on her.
Thanks to galvanic isolation, high mains voltage is reliably isolated and will not pass through the speaker and amplifier.
I took a plastic container and placed sockets there to connect the load. I made holes for the toggle switches and connected the entire system.

It's hard to find a person who doesn't like listening to music. To satisfy this desire, high-quality music centers, speakers and other devices are purchased. To get even more pleasure, many people think about creating special color effects that can decorate any sound and create a romantic atmosphere on a date or a fun mood when organizing a holiday party. Color music, like music centers, can be purchased, or you can make it yourself. The best option— make color music using LEDs with your own hands according to one of the proposed schemes.

Advantages of LED products

The modern electronics market presents a wide variety of LED strips that have a wide variety of color effects. With their help, you can create high-quality spot lighting; it is possible to create light music with flashing or blurry effects.

Unlike conventional light bulbs, LEDs have many positive characteristics. Among the main advantages of LED strips are:

• wide and varied range of colors;
• rendering rich colors;
• different design options - rulers, modules, discrete elements, RGB strips;
• high response speed;
• minimum amount of energy consumed.

The ribbons can be used at home, in clubs and cafes, and can be used to effectively illuminate shop windows. This article will describe in more detail the option of LED color music for ordinary home use.

Simple circuit with one lamp

To begin with, it is worth studying simple diagram color music. This is a device that consists of one LED, transistor and resistor. Power for such color music can be supplied from permanent source current voltage 6-12 volts. The device operates on the principle of an amplifier stage with common emitter. The impact in the form of a signal varying in frequency and amplitude arrives at the main base. As soon as the oscillation frequency exceeds a certain threshold value, the transistor opens and the LED immediately flashes.

This scheme of simple color music on LEDs has one drawback - the rate of blinking of the LED depends entirely on the level of production sound signal. In other words, the light effect will only be activated at a certain level of output music center volume. When the sound intensity decreases, the glow will be constant with occasional winks.

Scheme with one-color ribbon

This color music on a transistor is assembled using LED strip under load. To organize such color music, you will need to increase the power supply to 12 V, find and install a transistor with a maximum collector current that exceeds the load current, and you will also need to recalculate the total value of the resistor. This color music is quite simple, made on one single-color LED strip and is ideal for beginner radio amateurs. You can collect it without special problems at home.

Simple three-channel circuit

To get color music that is free of all the disadvantages listed above, you should use a special three-channel sound converter. This circuit is powered by LED strip constant voltage 9 V and is able to effectively illuminate one or two LEDs in each channel. Among the main structural elements that characterize such color and music scheme, you can note:

• three independent amplifier stages, which are assembled using transistors of the KT315 (KT3102) category;
• LEDs of different colors are included in the transistor load;
• For the pre-amplification element, a network small step-down transformer can be used.

The incoming signal is fed to the secondary winding of the transformer, which in turn performs two main functions - it decouples two devices at the galvanic level, and also amplifies the sound from the main linear output. After this, the signal is fed to three parallel and connected filters assembled on the basis of RC circuits. They operate on an individual frequency band, which directly depends on the value of the capacitor and resistor.

Color music with RGB tape

This attachment circuit operates on 12 volts and is ideal for installation on a car. This color music optimally combines the main functions of the previously discussed schemes and is able to work both in the lamp mode and in the color music mode. The second mode is achieved through special non-contact control of the RGB strip via a microphone. As for the lamp mode, it is based on the simultaneous launch of the green, red and blue LED at full power. The mode can be selected using a special switch located on a special board.

To understand how this attachment works, it is worth studying its sequence of actions. The main source of the signal here is a microphone, which converts sound vibrations emanating from the phonogram. The received signal is insignificant and therefore requires amplification. This can be achieved by using a transistor or a special operational amplifier. After this it starts automatic regulator AGC level. It effectively keeps sound fluctuations within reasonable limits and prepares it for subsequent processing. Built-in filters divide the signal into three parts, each of which operates in one specific frequency range. Finally, you just need to amplify the previously prepared current signal. For this purpose, special transistors are used that operate in key mode.

Purchase of a ready-made CMU

If you don’t want to make a color music system for use at home, you can purchase a CMU, that is, a color music installation. This is a ready-made functional solution that includes a controller. It will process the sound, converting it into a light and music visual representation. In the process of reproducing the light, its intensity and color scheme will change, thereby creating the effect of a real disco. The CMU device also includes a panel with built-in diodes.

These devices may be based on a spectral decomposition into frequencies, where each of them will correspond to a specific color scheme or preset adjustments with the most different effects and their alternation. They can be configured using the included remote control.

Important! Modern CMUs are very simple to install and configure. This is an ideal solution for organizing a home party or disco.

Conclusion

There are quite a lot of schemes for independently performing color music settings. You can choose a fairly simple option, where the color of the RGB tape will simply change, to quite complex ones, which will create a large number of various effects, overflows and attenuations. Depending on your skills, you can choose and execute the appropriate option. It is enough to work a little and create something truly unique; it will be lighting equipment that delights with the shimmer of a wide variety of color shades. Also, do not forget that there is always the opportunity to buy a ready-made color music solution and fill your home with color shades and joy.

Color music from a garland

Color music from a garland will add Have a good mood not only at home or in a bar where parties and discos are held. A motorist also needs it so as not to fall asleep while driving in many kilometers of traffic jams, and simply - the color music flashing in time evokes only admiration. From this article you will learn how to make color music from a garland without spending a lot of time and effort.
If you are a motorist and have decided that color music is very necessary in the car, then discard the idea of ​​​​purchasing it in a store. Of course, you can find everything today, but why spend extra money if you can assemble a completely unique example of color music from ordinary garlands according to the scheme.

The figure below shows a diagram of a color and music installation that works with 3 different lamps. At the same time, the power of the spotlights reaches 100 W each.

Thanks to this simple diagram, you can assemble the installation yourself.
Let's consider the most important provisions of this scheme:

• The main input is for wires going to the amplifier output. The connection is carried out as follows: remove one of the speaker wires (see) and in its place put the wire from the color music or in parallel, leaving everything as is.

Note. With this connection, the lights will blink in time with the music. In this case, lamp VT1 or VL1 will flash on the high frequency, and the other two, respectively, on the mid and low frequencies.

• The lamps themselves are connected by thyristors, which have control electrodes, and these, in turn, are supplied with voltage through filters on resistors and capacitors.

Note. To ensure that lamps or spotlights, as they are also called, operate at full intensity and the thyristors do not burn out, the network voltage is corrected using diodes. They are responsible for converting the voltage value from alternating to pulsating.

• The transformer in this circuit can be used from a single-program radio point. If you couldn’t find one, then an audio output transformer will do. The ideal option is from an old tube TV;
• As for thyristors, they are placed in metal cases. Their anode is brought out to the housing, and the cathode is located on top, and the control electrode is located below. The thyristors are fastened using nuts directly to the board.

Garlands and color music

So, New Year's garlands that decorate the Christmas tree are ideal as light bulbs. They need to be assembled together and then secured with electrical tape. This is what should happen.

To use garlands, you need to purchase or make an adapter. It will be intended to connect light bulbs to a car radio (see). Used as a wire twisted pair shielded cable.

Operation algorithm

So:

• We take several garlands. Their length should not exceed 1-2 meters;
• An LPT adapter is suitable as an adapter;
• We prepare a shielded twisted pair cable;
• We connect the garlands to the head unit using an adapter and wires;
• Turn on the car radio and go to the menu. We find the “flash zone”, which is responsible for setting color music (in Pioneer car radios).

Note. If the car radio is expensive, then it is possible to connect to the Internet. In this case, it will be easy to download one of the computer programs/players such as ALMP2 or KMPlayer. All that remains is to launch the selected player. The program will allow you to convert the frequency spectrum music track in the form of a data array.

• This array is processed and sent via USB port on . What happens is the following: the pulses of the music track travel through the channels to the garlands, and they begin to blink and real color music is formed.

Color music made of plexiglass

You can make color music in a car from plexiglass.
To do this you will need the following materials:

• 12 V adapter or battery;
• Headphone cable;
• Transistor, like KT817;
• 5 mm LEDs of different colors;
• Plexiglas;
• Fine skin;
• Electrical wire;
• Hot glue gun.

Let's get started:

• First of all, we make a box. We mark its diagram on paper;

Color music made of plexiglass

• We pass the cable from the headphones into the hole on the back wall of the box;
• We also insert the power plug and fix it with a hot-melt adhesive gun.

It will be possible to make an unlimited number of such boxes, where LEDs of various colors will be installed: red, green, blue. All these boxes can be placed around the entire circumference of the cabin ceiling or in another place. It will be very beautiful and the lights will start blinking to the beat of the music.

In the process of creating and connecting color music from garlands or other material, it will be useful to watch a video review on how this is done. Instructions, step by step photos, diagrams - all this is very important when working with your own hands.
Thus, the price of high-quality and reliably assembled color music will be minimal. Only consumables are purchased.

Often, to create the optimal atmosphere for a party, one important detail is missing - color music. How to be? Not everyone can rent such equipment. In this case, you can make your own color music. You don't need to be a genius to do this. In addition, everything you need for this can be found in any store. It is worth noting that original color music, created with your own hands, can decorate not only a separate room, but also a car. This allows you to relax well in a long traffic jam and, of course, not fall asleep. So, how to make color music with your own hands?

Design of LED garlands

This is the simplest LED color music. To make it, no special skills or tools are required. It can be made from ordinary New Year's garlands, which are used to decorate holiday trees. To make it you will need:

1. A special adapter for connecting to a computer.
2. LED Christmas garland.
3. Insulating tape.
4. Shielded cable.

Preparation of material

So, how do you make color music with your own hands? To begin with, you should prepare everything you need. To connect the garland to a computer, you will need a special adapter. Finding it won't be difficult. Indeed, in this case, you can use an adapter for the LPT port. In addition, you will need either a twisted pair cable.

How to assemble?

Of course, to make such a design you need to know at least an approximate diagram. IN in this case she's next. A signal from zero to 7 from the DATA pins is transmitted to the control circuit using eight conductors of a conventional “twisted pair”. In this case, a monitor is used as a ground transmitter desktop computer. Therefore, to get such color music, you will also need an adapter for the B plug. Otherwise, the structure simply cannot be connected.

Connection and testing

After all the parts are connected according to the specified diagram, you need to run one of the programs on your computer that allows you to work with color music. The well-known Winamp is suitable for this. The processed data array is transferred to the device via the USB port. As a result, the signal is output to eight twisted pair channels. This is what causes the LEDs to light up in a certain sequence. This is how you make color music with your own hands from an ordinary garland.

LED design

To get a beautiful color music, you need to prepare a neat plexiglass case, as well as the required number of LEDs. The result will be a very original design. To do this you will need:

Case manufacturing

So, let's prepare the body. To make it, you will need 4 rectangular plates with dimensions of 5 by 15 centimeters, as well as square plates - 5 by 5 centimeters. You need to cut them carefully so that the products turn out even.

Several holes should be made in one of the rectangular plates. One will be needed for headphones, and the second for power. Each of the body parts must be matted and sanded. The same thing needs to be done with LEDs. You can assemble the body using When the structure is ready, you can begin assembly.

How many LEDs do you need?

So, how many LEDs do you need to make good color music? You can do it quickly with your own hands. The main thing is to correctly calculate the number of parts needed. If you divide the operating voltage of the adapter by the operating voltage of one LED, you can get the required number of LEDs. In this case there are 4 of them.

Do-it-yourself color music: diagram

First you need to thread the audio cord through the hole. Now it should be connected to the transistor. After this, all the LEDs must be connected in series to the positive side of the battery or adapter. After this, all parts must be assembled in one housing. The adapter must be connected to the transistor via a minus. This is the main rule. Serial circuit LEDs must be connected to the transistor.

Particular attention should be paid to the audio cable. You can take it from old headphones. There are three cores under the braid. This is one common wire and several wires for the right and left channels. To assemble the circuit, you only need two. Usually there is a general one and one for channels. The third wire remains unused. Both wires are usually connected to the transistor. But the adapter is specifically for the channel wire involved. That's all, LED color music, created with your own hands, ready.

In order to throw a party at home, you need to think in advance about creating an appropriate atmosphere reminiscent of a nightclub. One of its main elements is color music. If you buy it in a company store, it will be quite an expensive pleasure. Therefore, in such situations, the question often arises of how to make color music from a garland. As a rule, this operation does not require special skills or special knowledge of electrical engineering. Enough to have on hand necessary materials and be able to work with simple tools.

Preparatory stage

To assemble the simplest color music, you need to prepare the following materials:

• LEDs 5 mm
• Electrical wire
• Transistor brand KT817
• 3.5mm headphone cable
• 12V adapter
• Plexiglas or plexiglass
• Fine sandpaper
• Thermal gun for gluing.

First you need to make a plexiglass box. It is usually made in the shape of a parallelepiped. To do this, 4 large and 2 small plates are cut out. It is best to choose average sizes so that they are neither large nor small. When cutting out plates, you need to make sure that there are no distortions, otherwise problems may arise during assembly.

In one of the walls, which will be the back, you need to pre-drill holes for the power cable and headphone cable. After all operations, the box must be made matte using sandpaper.

The next step will be installation. Their number is calculated depending on the output operating voltage of the adapter and the rated operating voltage of one LED. It is not recommended to use high-power LEDs and a power supply with a voltage of more than 12V.

Assembly of color music

Collect ready-made diagram It’s not difficult, you just need to know exactly the procedure. When deciding how to make color music from a garland, you must first of all thread the audio cord through the hole. Only the center wire and one of the channels are used.

After this, the LEDs are connected. It is necessary to carefully monitor the polarity so as not to mix up the leads. A transistor includes an emitter, a collector, and a base. The installed plug is secured with an adhesive gun.

After assembling the color music, the circuit needs to be checked for functionality. To do this, the plug is connected to a power source. If everything functions normally, then the assembly was completed correctly. At the end of all operations, all that remains is to secure top cover boxes Do-it-yourself color music will be great addition not only the party itself, but also the entire interior of the room.
