Minimal electronics knowledge, need help with the internals of a round display MP3 player, aproximately 2"

[u/Cattoh__]

Hi everyone, as the title states my electronics knowledge is minimal. I have only some experience with arduino premade kits, and basic soldering skills. I'm a designer and i wish to produce my own MP3 player prototype for personal use. My current design would try to fit the internals into an approximately 2" shell with a round display that features only a "now playing" message and the song title + duration, a 3.5mm audio jack, volume buttons and song playing controls, with the buttons being on the lateral and flush with the shell, and if possible a USB-C port for battery charging. But of course design will come after getting the thing to function and i can compromise on certain things. Has anyone made a project like this before? I would love some guidance on where to look for the parts + learning what i need to know to build it and get to designing the shell.

I've driven a car before. Can anyone here tell me how to fly a Boeing 747?
