JBL Flip 3 Emulator

Introduction

Welcome to my portfolio page dedicated to my JBL Flip 3 emulator project. The aim of this project is to reproduce the tactile and sonic experience of this iconic portable speaker using both hardware and software developed by myself.

Technical aspects:

• Hardware: battery charge management and voltage conversion to power an ESP32, which handles Bluetooth functionality as well as the various buttons and LEDs.

• Software: I use the Espressif audio development framework to develop a complete firmware. This controls volume, emits sounds for various actions and generates an audio stream via I2S communication between the ESP32 and a MAX98357 amplifier.

The system is modularly designed for ease of repair and maximum durability. I also took care to reuse components I already had in stock. I’d like to thank Adafruit, my main source of inspiration, notably through their “Aluminum Mounting Grid”, of which I printed a 3D copy with my Ender3, as well as for their excellent modules whose standard format I used.

Preparation phase

During this first phase of preparation, I made an inventory of all my components with a view to reusing them and not ordering new ones. I also took the time to extract the sound effects from the jbl flip 3. Here they are: found_bt.wav, maximum_volume_limit.wav, search_bt.wav, switching_off.wav and switching_on.wav.
