The music center can be built from an old cassette media center. With due diligence, you get a functional and completely modern device. The process of creating a device with your own hands will require imagination, a set of tools and a little experience with electrical engineering.

A homemade music center can be created from an old car radio. Most of these devices have a powerful amplifier in electrical diagram, What allow:

• Reproduce sound using suitable passive acoustics left over from an old tape recorder or turntable.
• Depending on the complexity of the device, play CDs, including digital formats.
• Install a radio antenna for which you can mount inside the speaker.

The photo shows an example music center hand made. In fact, this is the basis, which can then be brought to the desired level: create decoration, design a case, use computer modding tools.

Another way is to make a music center from an old turntable or tape recorder, using almost all the nodes of the donor device.

The radio tape recorder can be disassembled and placed electronic components inside the body of the old media center. Such work is not difficult: the design already contains an antenna and a power supply, which is often standardized and does not require modification.

Can accommodate an old radio in place of cassette decks not used due to obsolete storage media.

For the above options, the power supply can literally "roll underfoot" as well. Worn out, unusable due to a drop in power or slight deviation in parameters, computer power supplies are ideal.

In the comb that joins the motherboard, there are contacts for system start and low power bus with fixed voltage. To connect to a 220V network, the computer unit has enough four-pin connectors.

Electrical connection diagram

Although the radio tape recorders have a different number of output channels and different connection interfaces, it is not difficult to find a way to connect them to a 220 V network when creating a music center. The general wiring diagram is as follows:

As battery a computer power supply will be used. When choosing it, you need to make sure that the device is powerful enough to deliver 5A. Required contacts for joining:

ATX format power supplies will have to be run through a control pair of contacts. It is located on a 24-pin header:

In the diagram of the wiring diagram, it is already marked which of the connector cables to connect to the radio. Rear part in this case, the sound-reproducing device may look like this:

Depending on the model, the location of the power connector, the number of sound outputs and the set of other interfaces may vary. Only the color coding of the pad remains unchanged. The instructions for the radio tape recorder will help to determine the purpose of this or that wire.

Non-standard paths

Craftsmen who do not have this ready-made solution, like a car radio, can safely include fantasy. There are a lot of options:

You don't have to do much to accommodate all of these devices in the old media center. Devices need to be freed from their cases, maybe a little soldering iron work to bring the control buttons, slots for memory cards and USB to the front plastic panel of the center. The answer to the question of how to make a power supply scheme becomes clear if you count the number of outputs in a computer power source - there will be enough for everyone.

What if you want to do everything from scratch

If you want to mount everything in a unique case or use an old passive type acoustics for this purpose, you will definitely need amplifier... If the old one is lying around somewhere, the issue can be considered resolved. Those who do not have anything suitable at hand will have to improvise a little. The ideal place where you can find everything is the notorious AliExpress. Here you will find integrated circuits that are inexpensive and can provide a large output power per channel, as well as standard products that can be adapted to solve the task at hand - creating a music center.

Homemade panel for car radio

A homemade panel for a car radio is made by hand. Such a panel for a car radio or a frame, as it is called, will help to install any model of a car radio, regardless of whether it is suitable or not.

Several variants

Today, a large number of various frames for car radios are offered in stores, but this state of affairs does not save. The fact is that the factory panel does not always fit tightly and well into place, and this, in turn, gives rise to other problems.
We have to do the following:

• Or buy a new radio tape recorder.
• Buy a separate adapter frame.
• Make your own homemade panel.

Each of the above solutions has both disadvantages and advantages.

New radio tape recorder

So:

• When the user purchases, at times, expensive, and the head unit is not included in dashboard, or enters, but dangles, you have to return the model you like or change.

Note. Considering the high cost of the equipment, this approach is not entirely justified.

• In the store, when making a purchase, you must ask in advance about the sizes. A simple ruler or tape measure will help you avoid mistakes and immediately decide on the choice of a particular model.

Note. Strange as it may sound, but such a solution is not always able to eliminate the problem. The fact is that if the frame gets up, that's half the battle. The car radio will have to dock well with the installation site, and this is not always possible to achieve.

Separate adapter frame

So:

• Will give a high-quality and reliable installation. The adapter frame is screwed to the car panel, and then the car radio is installed. To date, the following types of frames have gained the greatest popularity: a separate frame for a car radio and a separate pocket frame for a car radio.
• There is not much difference between them. In the first case, just a frame is purchased, in the second, a pocket is also purchased.

Note. The frame pocket is a special plastic box that is open on both sides. On the one hand, the front panel of the device is inserted here, and on the other, external wires are brought in. Only the price of a frame with a pocket is more than the cost of a simple adapter frame.

With your own hands

So:

• The third option is considered the most correct, from any point of view: be it financial or practical.
• Such a panel will make it possible to connect to each other a new car radio of any size (1 or) and type with the car panel.

• Among other things, such a self-made frame does not require investment of any financial resources, because everything can be made from scrap materials.

Manufacturing process

So, we decided to make the panel on our own. In this case, we will definitely not lose.
So:

• To begin with, a mixture is made for filling. The putty must be thoroughly kneaded and allowed to settle. the right time(usually 20 minutes).
• We protect the front panel with something, for example, masking tape or a simple plastic bag.
• We wrap the inside with cardboard in order to fix the rectangle, which we remove.
• We apply the front panel, getting the required print.

Note. In some cases, an old DVD box is the ideal choice for a frame donor. It fits both in width (189 mm) and in height - (60) mm.

• After applying the putty, wait until it is completely dry and very durable.
• We take a rectangle from cardboard and set it strictly in the center, thus obtaining a kind of blank for filling. The rectangle itself must necessarily fit tightly, otherwise if gaps remain, problems cannot be avoided in the future.
• Buy epoxy from your local hardware store.

• We bring it home or to the garage. We put on fire to melt. Be sure to stir to get a homogeneous mass without lumps.
• Pour the resulting resin into a prepared mold. We give time to cool down.
• Then we remove the cardboard.
• Then we carefully take out the radio frame from the mold.

Note. We are faced with a rather rough form that requires processing.

• We put the form in a vice.
• We take a file and a skin with fine grain. We start the polishing process until we get a favorable appearance of the product.
• After that, we select the design of the frame. In other words, you need to choose the color of the paint with which you want to cover the product.
  Only first the frame will need to be treated with a primer, and only then with paint. Be sure to wait until the primer is dry, and only then apply the paint. In some cases, if one applied layer of paint does not give the desired effect, an additional second layer can be applied.

Reinstall the panel

The advantages and disadvantages of this manufacture

The above instructions, if followed strictly point by point, using video and photo materials, will provide valuable benefits. Why pay for services to specialists, the price of which is very high, if you can do everything calmly with your own hands.

In my new home, I wanted to install a stereo system without spending money. When I moved, I was lucky, I found an old car radio, which I had not used for a long time, and a couple of speakers. I also knew that I had an old power supply idle, and from all this I decided to build a homemade home acoustics from car speakers.

DIY components speaker system from car speakers:

• Car radio
• Speaker wires
• Car Speakers
• Speaker boxes (my speakers still had their own boxes)
• Power Supply
• The case for the entire system (it should fit not only the speakers of the system, but also the power supply unit - take into account all dimensions in the preliminary drawings)
• Stripping pliers and crimping pliers
• Something sharp to cut the box

Step 1: We collect all the necessary materials

To start assembling your home acoustics with your own hands from car speakers, collect all the necessary components.

Step 2: Connecting the Components

The power supply unit must not be plugged in!

Take the large plug from the PSU, from which there are many wires of different colors. You only need two of them - green and black. All black wires are ground. You have two options:

1. Connect the two pins as in the picture, or
2. Cut the two wires, strip them, twist them together.

I chose the second option, it seems to me more reliable.

Take the red and yellow wires from the bundle of wires from the radio, remove the insulation from them by 2.5 cm and twist them together.

Then connect them to the yellow wire from the PSU. Take the black wire (ground) from the radio harness and connect it to the black wire (ground) from the power supply.

If everything is connected correctly, then when you turn on the power supply to the network, the stereo system connected to it should turn on.

Step 3: box

I used a wooden box to make the box. Measure everything carefully before cutting anything.

Measure the size of the radio and draw a place for it on the wall of the box. I cut the hole a little smaller, because it is easy to expand it, but you can't make less.

The quality of the cuts in the photos is so awful because I only had an X-acto and a pocket knife on hand. But in view of the fact that this is a temporary audio system, everything suits me perfectly.

Cut a hole for the power supply plug. Drill holes for ventilation in the wall of the box next to the power supply fan. And you can even cut a square in the wall. The photo shows that I did not make enough holes.

Holes for wires are also needed, the size of the holes depends on the diameter of the wires.

Step 4: assembly

Place all components in the box. If you calculated and did everything correctly, everything should fit.

Step 5: connect the speakers

You can connect as many speakers as your radio allows. I connected two. They were in the factory boxes, in which I simply cut out the holes for the speakers and left the speakers in the boxes. The boxes coped well with the role of the box.

To connect the speakers, follow the instructions from the radio. If desired, you can connect front and rear speakers and make "surround sound". If your radio has an AUX output, you can connect it to your TV.

Step 6: pros and cons

This project was created purely for practical reasons. Later, I plan to make normal boxes for the speakers, and replace the box of the radio tape recorder with a larger one and more accurate in performance.

Pros of the project:

• Many speakers can be connected. I heard that some even connected a subwoofer and an amplifier.
• If you use old components, you can save a lot.
• You can watch videos on my radio, it has a radio receiver and a slot for an SD card.
• My radio also has an RCA connector, so if I want, I can connect it to any device with RCA plugs and display the image on the screen of the radio.

Cons of the project:

• The sound quality depends on the quality of the materials, therefore, until you assemble the case and test it, you will not know what the sound will be like.
• If you don't have the components in stock, the purchase can cost a pretty penny.
• At wrong connection components may burn out.

Hello to all DIYers! A friend recently gave away a burnt-out car radio he bought from a hypermarket with a working USB and FM. I connected it to the power supply - it worked. I disassembled it further, a piece of plastic was knocked out on the output microcircuit - everything is clear, the outputs are closed. I decided to restore it, fortunately, I had three free days, and I recently collected it.

I bit out the output microcircuit, soldered the power supply, inserted a USB flash drive and began to check the signal with a probe. Found the left and right sound channels. I connected it to the TA8205 and almost went deaf from distortion and a 50 Hz background. 3 hours of tambourines with dances and a solution was found. A resistor is 30 kilo-ohms at the input. And I did not figure out the power supply, I had to put a small 12 volt transformer and a stabilizer on the KRENK for the radio tape recorder.

The sound turned out to be more or less decent and powerful, for the garage it is the most. I decided to get confused with the case, right there in the garage I found a plastic speaker by the size of the front panel of the radio, I saw more than half of the case with a "grinder". I cut out a window for a panel, a radiator, a switch, terminals for an AU, cleaned it with a file. The transformer for the amplifier was put by a native from the center, it is switched on through a relay from the signal of the radio itself. I fastened everything with bolts, and where with hot melt glue.

Well, in addition, I decided to fit the output power indicators on the LM3915 into the case, since there were 2 pieces in the store, and recently I bought 500 pieces of 3 mm from the Chinese. LEDs for 250 rubles. I drew 2 scarves for microcircuits and LEDs, with a marker, the printer ran out of toner. I soldered the whole thing, connected it - it works. It turned out to be a good a la music center. The photographs show the entire assembly process.
