project reveal - 29.03.2026

yo frankom here, sorry about long gap in posts but it is what it is
if you may remember (probably not) in post about soldering i showed picture of hardware for my new project and since then i've been working on it (with some breaks but you know)

so this project is mp3 player! (uughhh let's name it wav player)
at first i was thinking about making it with esp32c3 board because it's small and i want this to be small and portable but i ran out of ports :(
i'm thinking about buying new board like esp32c6 or something (small but more ports!) but currently just temporarily switched to regular big esp32 board from my meteo station project

this size difference is funny

this is how project currently looks like

it reads songs from sdcard and display it as list where user navigate with rotary encoder and can output to headphones
it has 2 states - list and player in which buttons will behave differently
to have proper demo rn i need to fix player state, make pausing songs, turning volume up and down and probably something else... but playing songs, auto switching them and things like that works so it's great, maybe progress isn't as fast as it could be but i can work on it mostly at weekends when i'm not tired after schooooooooooooool

modules i use in this project:

• esp32 board
• microsd spi module
• sh1107 1,5" screen
• pcm5102a dac
• tpa6132 headphones amp
• ec11 rotary encoder
• simple buttons

my biggest inspo when it comes to look is transparent version of sony pocketstation

it probably wouldn't be possible for me to achieve this cool look and i don't have any 3d printer or something so my 2 ideas are:

• buy some dope looking device and put components inside of it but thing is that it would be haaaard to find ideal one to fit everything so it's mostly like dream
• and second which is more achievable is to buy something like pills holder and drill holes inside of it
  

i'll post something in this topic later so stay tuned if it interested you :D
bye!
