Do-it-yourself bluetooth receiver


Universal bluetooth receiver do it yourself from an old bluetooth headset with an 3.5mm jack audio jack.

I think it’s no secret to anyone how a bluetooth headset works.
This article describes how to make a more universal device for wirelessly playing music files while maintaining the functions of the headset.

This homemade It will be useful for drivers (to make and receive calls through the standard audio system), to listen to music through an AUX connection or on headphones.

We will need:
1. bluetooth headset
2. Audio jack 3.5mm jack
3. A pair of wires
4. Shrink
5. Super glue

From the tools:
1. Soldering iron

Step 1.
We need a 3.5mm jack audio jack. You can get it from old equipment, as I did, or buy it at any radio store.


Step 2
We carefully remove the speaker from the headset and unsolder the wiring from it.


Step 3
We place our audio jack 3.5mm jack most conveniently and solder the wiring according to the pinout and glue it with super glue.

Since the headset produces a mono signal (on one channel), we will combine the right and left channels into one, soldering them together with wiring. The photo shows that two red wiring are soldered to one channel. One goes to the headset, and the second connects the right and left channels. Now the mono signal from the headset will be sent to both channels. If this is not done, then when listening to the headphones, only one side will play, the same with any audio system.


Step 4
Now we put on a heat shrink, to isolate the contacts and the aesthetics of the appearance.

This is the end of the upgrade. We connect headphones or AUX cable and check.


The built-in battery allows you to work not for long. For this, take care of the additional power supply of the receiver for its continuous operation.

And then the meaning of the first post, if the description of homemade shows what and how changed.
There is a microphone, there is an answer button, I connected headphones, I can talk. What is not a headset.
No need to get out, you yourself write
due to the changed design, it will not work to use the headset before alteration.
That's what I said in the first post.

So now this is another device - the receiver. If the earphone from the device is stuck in the ear, and not the entire device is fixed as before, then the earth will not stop. The functions of receiving and conducting conversations are saved. I do not understand your pickiness for words. Either you are very fond of commenting, or you do not want to admit that the first post was thoughtless.

Perhaps you mean the inability to use it as before.

Naturally, this is the non-preservation of the functions of the device itself.

Functions are just saved. Perhaps you mean the inability to use it as before.
The bluetooth headset is a headset with a microphone, the so-called hands-free device.
And "Hedgehog is understandable" that due to the changed design, it will not work to use the headset as before. But you can connect any earphone and "pants turn into elegant shorts."

Just plug in the headphones and the headset will be the same.
That is, you yourself acknowledge that the headset functions of the device are not saved.

More versatile - widespread use, thanks to the AUX connector. Wireless connection of any wired headphones, stereo systems, car radios.
The microphone remained, the answer and call reset button remained. Just plug in the headphones and the headset will be the same.
The application is wide.
It is not clear how
