How to make a usb connector. The best programs to create a bootable USB flash drive

Even today, there are some modern cars that are equipped with radios without a USB connector, not to mention older cars. This state of affairs does not suit many car owners, which prompts the search for possible solutions. One of the available options to equip a USB head unit is to connect the input yourself, it's easy to do, but not all car radios accept this solution.

What is the USB input on the car radio

Many car owners are faced with a situation where the head unit in the car does not read music from a flash drive. And the whole problem is that the device simply does not have a USB input, i. it was not originally provided. Moreover, this situation is relevant not only for old cars, but on modern foreign cars you can often find such a distinctive feature. Almost everyone will agree that you want to listen to music in the car without any restrictions, and you can’t burn much on a CD. Yes, and the disks in the car today are somehow inconvenient and out of date. How to be, is there a solution to the problem? After all, replacing the radio, the pleasure is not the cheapest and not everyone can afford it. Below we will try to understand the situation in detail and find the best solution.

How to make and connect a USB input to the radio

Today, all kinds of electronic devices and devices do not exist, and, of course, the above problem has not been left aside. It is not necessary to change the head unit, it is enough just to improve the device. There are different options that we will consider.

USB adapter from an mp3 player for a regular tape recorder

For this method, we need the simplest mp3 player that can read music files of the appropriate format from both a memory card and a flash drive. An important feature: the player must have an audio output (jack) for headphones. A signal will be taken from it and fed to the radio. It is worth noting that to complete the procedure, at least minimal skills in working with a soldering iron are needed to avoid solder shorts during the soldering process and damage to the insulation of wires, elements, etc. The implementation of the player is done as follows:

1. We disassemble the radio and remove the CD drive or tape drive mechanism from it (if the radio is a cassette).
2. We take power from the standard device to power the player, the board of which we first remove from the case.
3. Depending on the player's supply voltage, you will have to implement a voltage converter circuit. For example, the car's on-board network has 12 V, and the player is powered by a 3.6 V Li-ion battery.
4. We take the sound signal from the output of the player and feed it to the AUX input of the radio. The connection will require a shielded wire, i.e. the wires must be braided. On the radio board, you need to find the audio input contacts. We solder the wire from the player to them.
5. We are mounting the player board inside the radio, since after removing the CD drive, the space will be freed. For convenience, the USB connector itself is located in a hole designed for cassettes or disks.
6. Connect the wires carefully to avoid a possible short circuit.
7. To control the player, the buttons are connected to unused buttons from the CD drive.
8. It remains to assemble the radio, install it in place and you can enjoy the music, for which it is enough to activate the AUX mode.

Thus, we assembled the USB adapter ourselves. With this connection method, the volume level on the radio should be made lower, which will eliminate the loud signal at a high input signal level.

DIY adapter

Consider another option for connecting a flash drive. In this case, you will need a plug from standard headphones, tulip-type connectors and a 4-wire copper-braided wire. An adapter will be made from these elements. For the procedure to be successful, the radio must have an AUX input. Before starting work, make sure that the wire from the headphones is not broken. To do this, nicknamed it a multimeter. The whole process is as follows:

1. We remove the insulation from the wire from the headphones and see the conductors of red and green, which correspond to the right and left channels (we cut off the headphones themselves). These conductors must be stripped and soldered to the middle contacts on the tulip connector.
2. The braid of the main wire is connected to the steel base of the “tulip”.
3. The finished adapter must have the following wiring: the signals of the right and left channels are fed to the middle contacts of the “tulips”, and the steel base is the common contact.
4. We connect an adapter to the external audio signal connector of the radio, with which you can connect any device: tablet, smartphone, player, etc.
5. It remains to activate the AUX mode and you can listen to music.

How to make an AUX connector

From the above, you can understand that the radio should have an AUX input. But what if there is no such connector, how to connect an external signal source in this case? There is a way out of this situation, and you can do everything yourself. For this we need:

• audio jack (standard 3-pin stereo jack);
• wire for connections (2 in screen);
• soldering iron and everything you need for it (solder and flux);
• multimeter.

After everything is prepared, you can proceed to dismantle the device. Let's consider the whole process using the Toyota Avensis head unit as an example. To remove it you need:

1. Pry off the decorative strip from the end on the right, pull along the entire length and remove it.
2. Disconnect the connector from the button responsible for heating the rear window.
3. The radio is fixed with two bolts. To unscrew them, you need to use a screwdriver with a magnet. Otherwise, the bolts will fall behind the panel.
4. To provide free access, the handbrake must be raised.
5. We move the selector to the central position and press the Shift Lock button, while the ignition must be turned off. In the corner we hook the selector panel by snapping off the caps.
6. Disconnect the connector going to the ashtray and remove the panel.
7. From below, more fixing bolts will be visible, which we carefully unscrew.
8. We take out the radio so that access to the connectors on the rear panel is provided.
9. Disconnect all connectors.

1. Remove brackets (left and right).
2. Using a flat screwdriver, we pry off the plastic locks of the front panel, after which we remove the panel itself.
3. Under the panel there is a seal, which we also remove.
4. We unscrew the bolts that connect the front panel to the side walls and the player. After that, the walls can be removed to the side.
5. Remove the back cover of the radio and the top of the player.
6. It is necessary to carefully lift the player, after which two cables will be visible and accessible. We take them out of the connectors and remove the player.

This completes the disassembly process. But before connecting the AUX connector, you need to understand the board and find two points (RCH and LCH). These points correspond to the two channels (outputs) of the player to the head unit. After the points are found, perform the following actions:

1. We take 3 wires of different colors (the best option is a shielded pair of cores) of small cross section and about 0.5 m long.
2. We connect one of the wires by soldering to ground.
3. Solder the other two wires to the right and left channels. For soldering use a low-power soldering iron 25-30 watts.
4. After the wires are soldered, you should write down what color wire corresponds to which channel.
5. The wires are wrapped in heat shrink tubing.

If there is a question of introducing an AUX connector into a cassette recorder, then the process is not difficult. On the front panel of the device there is a volume control with 3 outputs arranged in a row. We solder wires 25 cm long to the extreme conclusions. It is desirable that the wire be shielded, which will avoid interference. From the device, the wires are brought out. Alternatively, you can make a small hole in the side wall for them. It remains to connect the audio connector and in order not to get confused with the channels, our mark will come in handy. When the wires are soldered to the connector, they select a convenient place to mount it.

Upon completion of installation, check the performance of the speakers in radio mode. To supply an external signal (from an mp3 player, smartphone or tablet), use the appropriate audio adapter that connects the audio output of one of the listed devices to the AUX input of the radio. At the same time, you need to turn on the CD on the radio to activate the channels.

Connecting a flash drive to AUX - is it possible?

Many people wonder - is it possible to connect a USB flash drive directly to the AUX input of the radio? The answer is simple - you can't. And all because the flash drive needs power, plus there is simply no sound signal output from this type of media. To play music from a flash drive, there must be a reader. Those who buy an adapter of this type: on the one hand, an audio connector, on the other, a USB socket, connected to each other by a piece of wire, will be disappointed. Such an adapter will not work for the same reasons as listed above. In this case, you need to purchase a special adapter (adapter), which is not just a piece of wire, but a device assembled in a separate case.

Thus, we considered possible ways to get a USB connector for connecting a USB flash drive to a CD or cassette player. In fact, there is nothing complicated in this procedure. The main thing is not to rush during the soldering process, to perform actions carefully and connect the wires to the appropriate points. At the same time, the costs, compared with the acquisition of a new radio, are minimal.

In order to be able to connect a USB flash drive to the head unit, it is not necessary to buy a new expensive device. It is enough to make simple improvements and you can listen to music both from a flash drive and from other signal sources. This will require minimal skills in working with a soldering iron and a phased procedure.

In this article, I will describe several ways to make a bootable USB flash drive for free and without much effort:

Let me explain why I chose these three options, so:

The advantages of creating a bootable USB flash drive using the UltraISO program is that even in the trial (free) mode, this program will help you create a bootable USB flash drive without any problems and it also has many different functions. Cons (if they can be considered as such) is that it needs to be downloaded and installed, the installation process itself consists in pressing the Next button 4 times. In my opinion, the ideal third-party solution for creating a bootable USB flash drive for Windows XP, 7, 8.

Creating a bootable USB flash drive using the utility from Microsoft - USB / DVD Download Tool, the advantage of this method is that without special skills and abilities, thanks to a few mouse clicks, you get a bootable USB flash drive. Minus - an official (downloaded from the Microsoft website) ISO image of the operating system is required, otherwise the utility may not accept your ISO image and refuse to write it to a USB flash drive, or it will give an error when creating the image (I personally encountered such problems, which is why I consider it necessary to indicate them ).

And finally, creating a bootable USB flash drive using the Windows 7 command line. A big plus of this method is that you don’t need to install anything, but simply by entering a few commands, get a bootable USB flash drive with Windows XP, 7, 8. I don’t even know the disadvantages of this method ... probably only in its ugliness, since all commands are executed on the command line.

So, to create a bootable USB flash drive, you will need:

1 Flash drive with a capacity of at least 4 Gb (everything must be deleted from the flash drive, as it will be formatted)

2 ISO system image

3 BIOS, which will allow you to start the installation from a USB flash drive

4 Image creation utility (UltraISO, USB/DVD Download Tool)

If you have all this, then let's get started:

Create a bootable USB flash drive using UltraISO.

First of all, download the latest version UltraISO .

After that, start the installation of the program, click "Further"

We agree with the license agreement

Choose or leave the default installation location of the program

After that, the UltraISO program will open, click "File-Open"

Choose an ISO image of the system, in this example Windows 8 will be used

After that we press "Boot - Burn Hard Disk Image..."

In the next window, select the device on which the image will be written and click "Record".

After that, a warning window will appear stating that everything will be deleted from the flash drive, click "Yes".

The recording process will then start and last for a few minutes.

After the process of writing to a USB flash drive is completed, it becomes bootable.

How to make a DIY USB extension cable?

The conclusion is simple. If you don't have engineering talent, soldering experience, consumables, or USB cable pinout, it's much easier to buy an active extension cable, which can be easily used as a 5 meter USB extension cable, a 10 meter USB extension cable, a 15 meter USB extension cable, and so on. up to 50 meters! It is guaranteed to work with any device. If you have the listed talents, but absolutely little money, then you can make a USB extension cable with your own hands. It's not difficult at all.

Of course! There are absolutely no difficulties in this. All you need is:

Standard short USB cable, preferably with a ferrite core. The core serves to dampen high-frequency interference and is an indirect evidence of the good quality of the cable. You can buy, but it is better to beg from any IT specialist at work, they usually have a bunch of these cables.
- computer UTP cable of the required length (as short as possible in place). At the same time, the higher the category of the cable (5e, 6, 6e), the faster the speed of the device at the far end, or you can take a longer cable. The recommendation is the same, IT specialists have kilometers of this stuff.

A simple set of tools for the job. Nippers, although you can use ordinary scissors. A cable stripping tool, but as a rule, everyone uses a knife. Soldering iron, solder, rosin. Without this, nowhere - twisted wires have much greater resistance. And the last - heat shrinkage to give the design a professional look. If you don’t give a damn about beauty, feel free to replace it with ordinary electrical tape (adhesive tape is usually a thin layer of polyethylene with glue. It won’t work.)

So, when everything is ready, feel free to cut the free cable in half with scissors borrowed for 5 minutes from the accounting department. Then, with a knife taken from the public kitchen, carefully (not to make good contact, but not to cut yourself) remove the insulation by 3-5 mm. from all conductors.

In the USB cable we have 4 conductors, and in the UTP cable there are 8. Let's guess how many wires from the UTP cable need to be soldered to one wire in the USB cable? For those who did not go to school, we inform you that it is better for you to quit this idea altogether. And the rest carefully solder the conductors together, without confusing colors. Solder each pair of colored and variegated (coloured white) wires to one conductor of the USB cable at both ends of the UTP wire. If you managed to find heat shrinks of two diameters - thick and thin, then do not forget to put them on the entire cable and on each conductor of the USB cable BEFORE soldering. Then it will be somewhat inconvenient to do so. If you do not know what heat shrink is and where to get it, limit yourself to electrical tape.

When the soldering is successfully completed, there are no breaks and no soldered ends, move the heat shrinks to the place of the solder and heat them with an industrial hair dryer, in turn until they completely shrink and fit to the place of soldering. Who does not know what an industrial hair dryer looks like, always uses an ordinary lighter. Allow each heat shrink to cool, then gather everything into a neat bundle and do the same procedure with a large heat shrink, over the entire soldering point.

There is nothing difficult. However, before the first connection of some expensive device, it would be nice to ring the contacts with a tester, again asked from good IT people. They generally always have a lot of things that you can ask for. Golden people!

Attention! You perform all work at your own peril and risk. We are not responsible for your wasted time, your damaged nerves, cut or burned limbs, disabled office equipment, etc. It is better to trust professionals and buy a finished product that will surely be more beautiful, more functional, more reliable and faster.

When cassette recorders and CD players appeared, cars began to be equipped with car radios. But with the development of radio electronics, USB flash drives appeared, which completely replaced other media. They do not take up much space, you can record a large number of music files on them, while during the trip the music will not be interrupted by off-road driving. How to make a USB port (adapter) for regular radio tape recorders with your own hands is described in this article.

Guide on how to make a USB input in the car radio

Almost all modern cars are equipped with a car radio. Many drivers do not want to change it to a new Chinese device in order to get a USB input. In order to be able to listen to music from a USB flash drive, you need to connect a USB adapter to the head unit (the author of the video is oleg ko).

Training

It will not take much time, but you need to have some knowledge of radio engineering and be able to use a soldering iron. First of all, you need to purchase an MP3 player that can read flash drives and memory cards. It is important that it has a headphone output. This is necessary in order to be able to capture the audio signal.

You can use the FM trimmer, which is equipped with an audio output. The advantage of the trimmer is that it comes with a remote control.

Stages

Having bought a suitable device with an audio output, and having prepared the necessary tools, you can get to work.

The connection consists of the following steps:

1. We take out the device and remove the tape drive mechanism or CD-drive from it.
2. We solder the positive power wire from the player to the radio contact. After switching on, a voltage of 9 or 12 V should appear.
3. For an MP3 player, you need to include a voltage converter from 12 volts to 5 volts in the circuit. The trimmer has it built in.
4. To connect sound, you need to take a shielded wire and connect it to the audio output of the player. If there is no such wire, then you need to find a preamplifier on the board, it is to it that the wire that we need goes.
5. We find the output of the audio signal on the microprocessor. We solder the capacitors, and in their place we give an audio signal from the player.
6. Now install the MP3 player board. When doing this, be careful not to avoid a short circuit.
7. You can make a USB input a hole on the panel where discs or cassettes were inserted.
8. Buttons for controlling the player are displayed to the control keys located on the front panel.
9. Next, it remains to collect its staff in place.

Now you can listen to music from digital devices through a DIY USB port. To do this, turn on the TAPE or AUX mode. Tracks are controlled either using the buttons on the panel, or with the remote control if an FM trimmer was used.

Conclusion

Advantages of connecting a USB adapter to the radio:

• easy to install;
• the flash drive is devoid of the disadvantages of playing CDs when the laser burns out and there are problems with playing discs;
• many files are placed on the USB flash drive, they are easy to update and supplement;
• the recording is played in the quality in which it was recorded;
• you can use a standard device;
• The USB input does not take up the cigarette lighter.

Thus, connecting a USB port is not difficult. The main thing is to be able to use a soldering iron and understand at least a little in electronics.

By connecting your adapter for flash drives in the car radio, you can save on buying a new device equipped with a USB adapter.

Not all old tablets support the function of connecting a flash drive or modem, but I will tell you how to outsmart them and connect a flash drive, modem and even a hard drive to them.

Today I want to bring to your attention OTG - an adapter.

First I want to tell you what is OTG? This is a way to connect to your tablet or phone that supports OTG function, printer, flash drive and even hard drive. This connection is also called USB-host.

You can also connect a keyboard or mouse to your gadget, if the gadget supports such a function.

And so, to create this miracle cable, we need:
Old USB extension cable
Micro USB connector (you can get it from a regular USB cable for your device)
Soldering iron and soldering accessories

And so, let's go, in order for us to make such a cable, we will need to connect the 4th pin to the 5th pin of the micro USB connector

We need to get to the fourth pin and connect it with a jumper to the GND wire as shown in the picture.

But that's not all, to connect a hard drive to a phone or tablet, this adapter will not be enough for us. To connect devices whose consumption is more than 100mA, namely 100mA, the port of your device can give out, we will need to connect additional power to our OTG cable, which should be enough to make your hard drive work.

Here is a diagram of such an adapter

Now it's time to start collecting
We take an old USB extension cable and cut it not very far from the 2.0 connector, since the current is only 100mA to avoid large losses. Cut off approximately in the place as shown in the photo

After we clean our wire

I connected with a drop of solder 4 and 5 pins.

Well, here is our entire cable assembly

It remains only to check the performance, take the tablet, insert the “adapter” and insert the USB flash drive into it, everything works, as the flashing LED on the USB flash drive and the tablet identifying the USB flash drive tell us.
