Make Your Own Low Budget Bluetooth Music System

In this project I will show you how I "fused" a dirt cheap bluetooth music receiver with an old speaker of mine. The main focus will be on designing a low cost audio amplifier circuit around the LM386 and the NE5534. The bluetooth receiver costs 4,5$ and the audio amp 3$. So you can call this low budget.

The video gives you all the info you need to build this project. But in the next steps I will present you my part list and my schematics to make things easier.

No matter which circuit you want to build, you will need at least the receiver. Here is where I got mine from (affiliate links):

And if you do not want to build the amp circuit by yourself, you can always buy a premade kit. Here is a nice one (affiliate links):

Here you can find the schematic for the LM386 and the NE5534. You can also use the board design that I made. I used this as well and it works perfectly fine.

You did it. Now you can enjoy the awesome music of your homemade audio amp .
