Music Player v1 is a interactive media device (media form: music, voice recording, text, gifs and video possibly) powered by an ESP32-S3.I designed it as a personalized gift,to play unique music, affirmations, every single day onpre-programmed schedule. v2 will have an APi endpoint to post voice recordings over the internet and other cool features. The device is a complete package for audio related projects and can be modified into other creative ideas like - (voice journal keeper, online music streaming and many more!)
- Daily Present: Automatically fetches unique content (music and text(affiramtions/notes)) from an SD card based on the current date.
- High-quality Audio: Uses I2S protocol with a MAX98357A DAC for clear, non-blocking WAV file playback.
- Voice Recorder: Record and save voice memos directly to the SD card for future playback ** Plans to stream it over the internet
- Music Player: Plays music playlists from the sd card
- Peculiar Cute design Cute 3d model case enclosure with a tounge sticking out 😛
The system integrates an ESP32-S3 with I2S audio, SPI SD card communication, and I2C/SPI display interfacing.

I built it becasue I really wanted to get into making a custom esp32 chip board and happened to stumble upon a music player gift idea. And from there I spiralled into making the best version of my idea. It plays a different song and displays unique affiramtions from a predefined library to bringten up someones day. OFC my handcrafted playlist library is the biggest treasure :). You can build your own too! For yourself or for someone else. Good Luck >> After you complete it, share it with me from the info at fo at https://manishd.is-a.dev/ .
Created with love❤️.
