So thats all you will need and the below links will help you buy the Bluetooth Transreciever:


Step 2: The Schematic and the Main Concept

Intially i will share you the schematics as shown in the

picture. I apologise as first i had decided to line up the 5v suppy with the PCB but we need to use diffrerent lines as there will be electromagnetic fluctuations between the speaker an thee bluetooth reciever.


1.We create a mini amplifer for our speaker to have a good loud sound.

2.We add a bluetooth transrecievr to it.

3.We Give power supplies to both the transreciever and the speaker seperately.

4.We connect the speaker to the bluetooth transreciever and then play songs wirelessly!

5.To make it compact and awesome , we add a strap to attach it to our hand and enjoy it.

Happy Making !

Step 3: Soldering Time!

So Lets Solder the components as per the schematics . The final result must be similar to the picture. Anyway its your creativity.The main concept is important here.As I explained the main concept before this is very simple and be careful and take safety precautions while soldering!

Step 4: Casing Our Speaker.

First test it out and when it is successful we must case it.

Lets put it up in a altoids tin , here I had used a visiting card holder which makes it very compact and it looks awesome.Just add a strap and make it portable!
