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.

Step 1: Watch the video!

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.

Step 2: Get the bluetooth receiver and/or your premade amp!

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

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:

Step 3: Order your parts for the circuit!

Now it is time to order the parts for your circuit. Here is a list of what you will need and where you can buy it:
