MP3

Oooh, an MP3 player! I wanted to build this myself to be able to distance from my phone and still listen to music (if you want to read my full thoughts, see the section below)!

It features:

• two AUX jacks,
• a battery,
• a screen,
• 6 buttons (plus an additional switch to turn the device on or off),
• a microSD card and
• a microUSB port!

My thoughts (click to expand)

I personally dislike my phone. The aspects of always being connected, the aspects of always having a possibility to get distracted are reasons why I would sometimes prefer to not take my phone with me. But there is one problem when I don't have my phone: How am I supposed to listen to music? Therefore, my idea is to make my own MP3 player. I want to make it minimalist, yet functional. My goals are the following features: - It has an own battery - It has an AUX port (optional but an additional 1/4 inch port) - It has a battery - It has a USB-C port for charging the battery and adding files to the MP3 players library - It has a screen - It has at least 6 buttons (left & right, up & down, select and back) The idea is not super polished yet, but I really want to build this. My goal is it, to make the MP3 player so small, that it can fit in your pocket easily without annoying you too much. Without having ever seen or held a Gameboy before, this is the formfactor I am aiming for - at least the formfactor I would imagine a Gameboy to have. Will I really make this? I am unsure, but I really want to.

The Building Process

I built this project over various months without ever really finishing it. Often, I just opened KiCad to make super small details. This also is my first somewhat complex CAD project!

The CAD model

Everything can easily be put together. It should work with only two bottom screws, though some glue may be applied to increase sturdiness.
