Bluetooth Amp Project

Difficulty rating: Beginner
Average time to build: 30 minutes



Short description

This DIY kit is a nice little project that will teach you a lot about soldering and how a Bluetooth decoder works, it will also teach you how an amplifier works. This DIY kit will teach you how to solder wires. The kit will also teach you how speakers work and how they need to be connected.

Bluetooth Amp building summary.

In this project, you will need the kit as well as a soldering iron, solder and pliers to cut the wires and you will also need a wire stripper to strip the wires to reveal the wire itself.

How the Bluetooth Amp works

The Bluetooth Amp works as a small walk around with boom box for kids that they can connect to while using their phones.
The amplifier that comes with this DIY kit is used to amplify the sound quality of the speakers.
The Bluetooth decoder supports lossless MP3, WMA, and WAV format songs.
The battery holder works with one single cell of the 18650 batteries, and this is to give it power.

Step-by-step instructions.


The above picture shows all the components that come with the kit.


Please note that you will need to remove the 5V regulator on the Bluetooth decoder (for this project only) when the 5V regulator is not removed and replaced with either solder or a 0Ohms resistor link this project will not work. Plug in the power cables to the amplifier using the female to female jumper wires. Plug in the connectors of the Bluetooth module on to it.



Solder the power jumper wires of the speakers on to the speakers pins.

Step 3.

Solder the jumper wires from the speaker onto the amplifier, make sure that the positive and negative wires are connect to the corresponding pins on the amplifier. You'll need to do this for both of the speakers.


 Step 4.

Finally take the battery holders cables and insert them into the power wires from the amplifier. For a better connection you can also solder jumper wires on to the power cables of the amplifier.
