How to make a music center do it yourself

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

Standard way

Homemade music center can be created from the old car radio. Most of these devices have a powerful amplifier in the electrical circuit, which allows:

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

The photo shows an example of a handmade music center. In fact, this is the basis, which can then be brought to the desired level: create decoration, decorate the body, use computer modding tools.

Another way is to make a stereo system from an old player or tape recorder, using almost all the nodes of the donor device.

The radio tape recorder can be disassembled and its electronic components placed inside the enclosure of the old media center. Such work is not difficult: the antenna and power supply are already present in the design, often standardized and not requiring improvement.

You can place the old tape recorder in place of tape decksnot used due to outdated storage media.

For the above options, the power source can also literally "roll under your feet." Worn, unsuitable for use due to a drop in power or a slight deviation of parameters, computer power supplies are ideal.

In the comb, which is connected to the motherboard, there are contacts to start the system and low-power bus with a fixed voltage.To connect to the network in 220V at the computer unit enough four-pin connectors.

Electrical Connection Diagram

Although the recorders have a different number of output channels and different connection interfaces, finding a way to connect them to the 220 V network when creating a music center is easy. The general switching circuit is as follows:

A computer power supply unit will be used as the battery. When choosing it, you need to make sure that the device is powerful enough to issue 5A. The necessary contacts to join:

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

In the figure, the wiring diagram already indicates which connector cable to attach to the radio tape recorder. The back of the audio reproducing device may look like this:

Depending on the model, the location of the power supply, the number of audio outputs and the range of other interfaces may vary. Unchanged is only the color marking pads. The instruction to the radio tape recorder will help determine the purpose of a wire.

Non-standard ways

Home craftsmen who do not have such a ready-made solution as a car stereo can safely turn on a fantasy. There are a lot of options:

1. As a power supply can be used computer or suitable for power and voltage pulse: from home appliances, mobile phones.
2. Suitable computer drives that have audio output. Such a device is usually equipped with a start button, it also serves to go to the next track, a double-click stops. Some older drives, such as the Creative brand, are equipped with a full set of control keys, as well as a volume control on the front panel.
   
3. Want to listen to the radio? A small radio the size of a matchbox, receiving a signal from a retractable antenna, will sound perfectly high quality.
   
4. There are no problems with digital formats. An inexpensive FM transmitter paired with the already mentioned tiny receiver is an ideal way to get high-quality sound.
   
5. For the very lazy, there is an ideal donor - an old, but working electronic alarm clock. Chinese models easily act as radio, read digital formats from memory cards.
   

To accommodate all these devices in the old media center there is practically nothing to do. Devices need to be freed from the cases, maybe a little soldering iron to bring the control buttons, connectors for memory cards and USB to the front plastic panel of the center. The answer to the question of how to make a power circuit becomes clear, if you count the number of outputs in a computer power source - they are enough for everyone.

What if you want to do everything from scratch

If you want to mount everything in a unique case or use the old passive type acoustics for this purpose, you will definitely need amplifier. If somewhere old was lying around, the question can be considered solved. Those who do not have anything suitable at hand will have to improvise a little. The perfect place for everything is the well-known AliExpress. Here you will find both integrated circuits that are inexpensive and can provide greater output power per channel, as well as standard products that can be adapted to solve the task posed - the creation of a music center.
