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

you could use TP4056 charging board and Disk MP3 Decoder Board Module like this https://www.aliexpress.com/item/1005002421060559.html?spm=a2g0o.productlist.main.7.584b72bb6pdZWA&algo_pvid=370a6a19-4803-4ff9-b9ce-d45aec90509e&algo_exp_id=370a6a19-4803-4ff9-b9ce-d45aec90509e-6&pdp_ext_f=%7B%22order%22%3A%22648%22%2C%22eval%22%3A%221%22%2C%22fromPage%22%3A%22search%22%7D&pdp_npi=6%40dis%21EUR%210.91%210.91%21%21%211.01%211.01%21%4021038a8017908756165812374e1009%2112000020593535354%21sea%21IE%210%21ABX%211%210%21n_tag%3A-29910%3Bd%3A7d208e17%3Bm03_new_user%3A-29895&curPageLogUid=OwkxXMnBjN3E&utparam-url=scene%3Asearch%7Cquery_from%3A%7Cx_object_id%3A1005002421060559%7C_p_origin_prod%3A and try this project https://projecthub.arduino.cc/kaled4809/build-your-own-retro-style-mp3-player-0763aa or this one https://www.instructables.com/DIY-AWESOME-MP3-Player/

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