Color music 12th century. Making color music from LED strip

simple scheme of color music using 220V lamps

Everyone knows and almost everyone assembles this device that flickers and blinks to the music - color music. On the Internet, many search for color music schemes using various queries and they are different everywhere. I present to your attention the diagram below, the appearance of which you see in the pictures. And so, circuit of working color music for 220 Volts on teristors

A simple color scheme

It will require the bare minimum of parts.

We buy colored incandescent lamps 220V
Considering that the output stage of the color music is made of thyristors, it has a lot of power. If thyristors are placed on heat sinks, then each channel can be loaded with 1000 watts. But for a home, 60-100 watt lamps are quite enough.

Drawing of a printed circuit board for light and music

I did not use laser-iron technology for such a simple board design. I simply printed the image as a mirror image and placed it on the foil.

To prevent the paper from moving, we secure it with tape or something else and mark the places of future holes

We paint the tracks themselves with nitro paint

Any transformer from a Chinese power supply, whether from a radiotelephone or something else, will be suitable as a transformer.

How to make color music with your own hands? There are many options, most of them are difficult to assemble and the average person is often unable to assemble them. After wandering around the Internet, I found one scheme that is very simple. Anyone can make color music with their own hands using LEDs using this circuit.

You will need:

LEDs (5 mm);
3.5 cable from headphones;
transistor KT817 (or its equivalent);
12V adapter;
wires;
plexiglass;
glue;
sandpaper (fine).

We make a housing in which the LEDs will be located. We mark out future body parts. 4 walls measuring 15x5 cm and 2 measuring 5x5 cm.

Cut it out. You need to cut as evenly as possible, otherwise all the irregularities will have to be processed.

We select a plate that we will install as the back wall of the color music housing. Let's make two holes in it. One is for the power cable and the other is for the headphone cable.

We process the walls of the color music box with sandpaper to give the effect of light scattering throughout the box.

LEDs also need to be sanded.

Now let's assemble the body by gluing the walls together.

While the glue dries, let's do the calculations. You need to calculate the number of LEDs.

Output operating voltage of the adapter / rated operating voltage of one LED = required number of LEDs.

If you use a 12V power supply you get:

12V / 3V = 4 pcs.

Next, let's deal with the 3.5 cable from the headphones.
The cable consists of three wires: 2 wires for the left and right channels (red and white) and 1 wire for the common wire.
To implement color music, we need a wire from one of the channels (right or left, it doesn’t matter) and a common wire.

Before starting to assemble the circuit, we thread the wires through the holes in the box.

When assembling the diagram, remember:
- LEDs have polarity
- do not overheat the transistor and do not mix up its terminals (E - emitter, B - base, K - collector)

After assembly, check the operation of the color music. If everything works correctly, then glue the top cover of the box.

DIY color music using LEDs is ready!

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 is to 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’s worth studying a simple color music scheme. This is a device that consists of one LED, transistor and resistor. Power for such color music can be supplied from a constant current source with a voltage of 6-12 volts. The device operates on the principle of an amplification stage with a 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 using LEDs has one drawback - the rate of blinking of the LED depends entirely on the level of the sound signal produced. In other words, the light effect will be activated only at a certain level of volume produced by the music center. 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 an LED strip in the 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 assemble it without any 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. Such a circuit is powered from an LED strip with a constant voltage of 9 V and is able to effectively illuminate one or two LEDs in each channel. Among the main structural elements that characterize such a color-musical scheme are:

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, the automatic AGC level controller starts. 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 have a specific color scheme or preset adjustments with a variety of 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 in the process of work will create a large number of different 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 equipment that changes color, intensity, effects and rhythm is an integral attribute of a good party, capable of lifting and moving to the beat of the music of the laziest and most melancholy of the event participants. In this article we will discuss the nuances of LED color music, the possibilities of making it yourself and options for use in various conditions.

With the saturation of the market with LED lighting equipment, the scope of its application is expanding exponentially and is no longer limited solely to design delights in interior lighting, conciseness and efficiency in lighting offices and work lighting, or the desire to create durable and high-quality lighting for the exterior of buildings. LED lamps have penetrated into all areas where their colossal technological advancement, energy efficiency, minimal dimensions with maximum output can serve well and bring benefits or aesthetic pleasure - car tuning, phytolamps for growing home gardens, and, of course, color music.

Color music using LED components has a number of significant advantages over analogues using outdated lamps:

The small size of LEDs, combined with energy efficiency, gives rise to an abundance of possible forms for creating light and music equipment, and we are talking not only about external form factors, but also about the possibilities of using LEDs in a wide variety of effects when working with light and its various colors, because the LED element can produce a point stream of light. Strobes, spotlights, disco balls and much more are available for use even at home.
The safety of using color music or LED emitters is maximum, compared to outdated lamps - the operating temperature range of LED elements does not exceed 60 degrees Celsius, which means that there should simply be no concern about the fire of any home decor elements or materials. Let the colors fill your home along with the music without any of the hassle of using lights and music equipment.
The long service life of color music for the home makes the purchase of such equipment advisable, because it is designed for 8,000-10,000 thousand hours of operation, that is, a whole year of uninterrupted service. And taking into account the fact that the number of switches on and off does not in any way affect the consumer properties of LED elements, and most people do not organize round-the-clock parties every day, home color music can delight its owner and his guests for many years.
Quality of color and light transmission. LED lighting has the widest range of colors and shades, which is one of the main advantages for color music as such, because a variety of colors plays an important role in creating the atmosphere. Also, unlike laser color music, LED equipment is harmless to the eyes and cannot damage vision when the light flux directly hits the retina.

Options for creating light and music lighting at home

The simplest option is to buy a special portable lamp or lamp that will change colors or use several colors at once, with one or more effects. There are a lot of such options, they are very common and budget-friendly. For an entry-level player, to please yourself and your friends with a simple but enjoyable game with bright lights and colors accompanied by music, it will be quite enough.

The best quality option, if you don’t do it yourself using the most complex schemes, is to purchase a ready-made solution, the so-called CMU (Color Music Units). This is a ready-made solution that includes a controller that will process the sound signal, turning it into a light and music performance, changing the intensity and colors of light streams, creating the effect of a full-fledged disco, and directly panels with diodes. CMUs are easy to install, and if you want to create a disco at home with your own hands, this is a very good option. Such DMUs can be based on spectral decomposition by frequencies, when each frequency will have a corresponding color, or specified adjustments with all sorts of effects and their alternation, which can be configured using the included remote control.

The third option is to assemble the color music yourself. There are a lot of detailed diagrams on the Internet, according to which a person with experience in working with electronics can make color music for the home with his own hands. You can do without circuits by using a separately purchased color and music controller and, say, several pieces of RGB tape. In fact, as for lighting devices for disco effects, created with your own hands, there can be a really huge variety of them. There are a lot of diagrams, as well as video instructions on how to assemble equipment using these diagrams. There are schemes using external microphones; lighting devices assembled according to these schemes will change color and effects exactly to the playing melody.

The schemes offered on the Internet for making color music with your own hands are as diverse as possible - from the simplest, when the color of the RGB tape will change, to the most complex, with many effects, attenuation and overflows. Depending on your skills, you can choose the appropriate option, find the right scheme and create something unique, lighting equipment that will delight you and your guests with the shimmer of all colors. If you are not ready to make LED color music yourself, with your own hands, then you can turn to the ready-made solutions market and fill your home with a variety of colors and joy.

The inexhaustible potential of LEDs has once again been revealed in the design of new and modernization of existing color and music consoles. 30 years ago, color music, assembled from multi-colored 220-volt light bulbs connected to a cassette recorder, was considered the height of fashion. Now the situation has changed and the function of a tape recorder is now performed by any multimedia device, and instead of incandescent lamps, super-bright LEDs or LED strips are installed.

The advantages of LEDs over light bulbs in color music consoles are undeniable:

wide color gamut and more saturated light;
various design options (discrete elements, modules, RGB strips, rulers);
high response speed;
low power consumption.

How to make color music using a simple electronic circuit and make LEDs blink from an audio frequency source? What options for converting an audio signal are there? Let's look at these and other questions using specific examples.

The simplest circuit with one LED

First you need to understand a simple color music circuit, assembled on one bipolar transistor, resistor and LED. It can be powered from a DC source with a voltage of 6 to 12 volts. This color music works on one transistor according to the principle of an amplification stage with a common emitter. A disturbing influence in the form of a signal with varying frequency and amplitude arrives at the VT1 base. As soon as the oscillation amplitude exceeds a certain threshold value, the transistor opens and the LED flashes.

The disadvantage of this simplest scheme is that the rate of blinking of the LED depends entirely on the level of the sound signal. In other words, a full-fledged color-musical effect will be observed only at one volume level. Lowering the volume will result in a rare wink, while increasing the volume will result in an almost constant glow.

Scheme with single-color LED strip

The simplest color music above on a transistor can be assembled using an LED strip in the load. To do this, you need to increase the supply voltage to 12V, select a transistor with the highest collector current exceeding the load current and recalculate the resistor value. This simple color music from an LED strip is perfect for beginning radio amateurs to assemble with their own hands, even at home.

Simple three-channel circuit

A three-channel audio converter allows you to get rid of the shortcomings of the previous scheme. The simplest scheme of color music with the division of the sound range into three parts is shown in the figure.
It is powered by a constant voltage of 9V and can illuminate one or two LEDs in each channel. The circuit consists of three independent amplifier stages assembled on KT315 (KT3102) transistors, the load of which includes LEDs of different colors. As a pre-amplification element, you can use a small step-down network transformer.

The input signal is fed to the secondary winding of the transformer, which performs two functions: it galvanically isolates the two devices and amplifies the sound from the line output. Next, the signal goes to three parallel-connected filters assembled on the basis of RC circuits. Each of them operates in a specific frequency band, which depends on the values of resistors and capacitors. The low-pass filter passes sound vibrations with a frequency of up to 300 Hz, as indicated by the blinking red LED. Sound in the range of 300-6000 Hz passes through the mid-pass filter, which is manifested in the flickering of the blue LED. The high-pass filter passes a signal whose frequency is greater than 6000 Hz, which corresponds to the green LED. Each filter is equipped with a trimming resistor. With their help, you can set the uniform glow of all LEDs, regardless of the musical genre. At the output of the circuit, all three filtered signals are amplified by transistors.

If the circuit is powered from a low-voltage DC source, then the transformer can be safely replaced with a single-stage transistor amplifier.
Firstly, galvanic isolation loses its practical meaning. Secondly, the transformer is several times inferior to the circuit shown in the figure in terms of weight, size and cost. The circuit of a simple audio amplifier consists of a KT3102 transistor, two capacitors that cut off the DC component, and resistors that provide the transistor with a common emitter. Using a trimmer resistor, you can achieve overall amplification of a weak input signal.

In the case when it is necessary to amplify the signal from the microphone, an electret microphone is connected to the input of the previous circuit, applying potential to it from the power source. The circuit of a two-stage preamplifier is shown in the figure.
In this case, the trimming resistor is located at the output of the first amplifier stage, which gives more opportunities for adjusting sensitivity. Capacitors C1-C3 pass the useful component and cut off the direct current. Any electret microphone is suitable for implementation, for which a bias of 1.5V is sufficient for normal operation.

Color music with RGB LED strip

The following circuit of a color music console operates on 12 volts and can be installed in a car. It combines the main functions of the previously discussed circuit solutions and is capable of operating in color music and lamp modes.

The first mode is achieved through contactless control of the RGB strip using a microphone, and the second mode is achieved through the simultaneous illumination of red, green and blue LEDs at full power. The mode is selected using a switch located on the board. Now let’s take a closer look at how to make color music that is perfect even for installation in a car, and what parts are required for this.

Structural scheme

To understand how this color music console works, let’s first consider its structural diagram. It will help trace the full path of the signal.
The source of the electrical signal is a microphone, which converts sound vibrations from the phonogram. Because This signal is too small and must be amplified using a transistor or operational amplifier. Next comes the automatic level controller (AGC), which keeps the sound fluctuations within reasonable limits and prepares it for further processing. Filters divide the signal into three components, each of which operates only in one frequency range. In the end, all that remains is to amplify the prepared current signal, for which transistors operating in switching mode are used.

Schematic diagram

Based on the structural blocks, we can proceed to a consideration of the circuit diagram. Its general appearance is shown in the figure.
To limit current consumption and stabilize the supply voltage, resistor R12 and capacitor C9 are installed. R1, R2, C1 are set to set the microphone bias voltage. Capacitor C fc is selected individually for a specific microphone model during the setup process. It is needed in order to slightly muffle the signal of the frequency that prevails in the microphone’s operation. Usually the influence of the high-frequency component is reduced.

Unstable voltage in the vehicle network can affect the operation of color music. Therefore, it is most correct to connect homemade electronic devices through a 12V stabilizer.

Sound vibrations in the microphone are converted into an electrical signal and, through C2, are supplied to the direct input of the operational amplifier DA1.1. From its output, the signal goes to the input of the operational amplifier DA1.2, equipped with a feedback circuit. The resistances of resistors R5, R6 and R10, R11 set the gain DA1.1, DA1.2 equal to 11. The elements of the OS circuit: VD1, VD2, C4, C5, R8, R9 and VT1, together with DA1.2, are part of the AGC. At the moment a signal of too large an amplitude appears at the output of DA1.2, transistor VT1 opens and, through C4, closes the input signal to the common wire. This results in an instantaneous reduction in the output voltage.

Then the stabilized alternating current of audio frequency passes through the cut-off capacitor C8, after which it is divided into three RC filters: R13, C10 (LF), R14, C11, C12 (MF), R15, C13 (HF). In order for the color music on LEDs to shine brightly enough, you need to increase the output current to the appropriate value. For tape with a consumption of up to 0.5A per channel, medium-power transistors such as KT817 or imported BD139 without mounting on a radiator are suitable. If the do-it-yourself light-music assembly involves a load of about 1A, then the transistors will require forced cooling.

In the collectors of each output transistor (parallel to the output) there are diodes D6-D8, the cathodes of which are connected to each other and connected to switch SA1 (White light). The second contact of the switch is connected to the common wire (GND). While SA1 is open, the circuit operates in color music mode. When the switch contacts are closed, all the LEDs in the strip light up at full brightness, forming a total white stream of light.

Printed circuit board and assembly parts

To make a printed circuit board, you will need a single-sided PCB measuring 50 by 90 mm and a ready-made .lay file, which can be downloaded. For clarity, the board is shown from the side of the radio elements. Before printing, you must set its mirror image. Layer M1 shows 3 jumpers placed on the parts side.
To assemble color music from an LED strip with your own hands, you will need accessible and inexpensive components. An electret type microphone, suitable in a protective case from old audio equipment. Light music is assembled on a TL072 chip in a DIP8 package. Capacitors, regardless of type, must have a voltage reserve and be designed for 16V or 25V. If necessary, the board design allows you to install output transistors on small radiators. A terminal block with 6 positions is soldered on the edge for supplying power, connecting an RGB LED strip and a switch. A complete list of elements is given in the table. In conclusion, I would like to note that the number of output channels in a homemade color music set-top box can be increased as many times as desired. To do this, you need to divide the entire frequency range into a larger number of sectors and recalculate the bandwidth of each RC filter. Connect LEDs of intermediate colors to the outputs of additional amplifiers: violet, turquoise, orange. Do-it-yourself color music will only become more beautiful from such an improvement.
