PhoniESP32 🎶🔋

A kid-friendly jukebox powered by the ESP32, inspired by Phoniebox. Unlike the original Raspberry Pi–based version, phoniesp32 is designed to be battery-operated, low-power, and ultra-portable.

✨ Features

• ESP32-based jukebox: replaces the Raspberry Pi with an ESP32-C6.
• Low-power & battery-ready: runs on a Li-ion cell with TP4056 charging and MT3608 boost converter.
• Bare-metal Rust firmware: built on the embassy async embedded framework.
• Rust-powered Web UI: implemented with Dioxus and served directly from the ESP32.
• Audio transcoding & upload: convert music files via the web frontend to IMA ADPCM, upload to device, and play back instantly.
• RFID support: scan S50 fobs with a MFRC522 module to trigger playlists.
• Affordable: target build cost under 50 CHF.
