This is a prototype of a handheld voice recorder. It uses the adafruit music maker wing with an Unexpected Maker ESP32-S3 board and an I2S MEMS microphone.

There’s also a button! Pressing and holding records a new audio file. Double clicking cycles through the audio files. Clicking once plays the ‘current’ one. The files are stored in an on-board SD card.

I’m planning on improving it in the future! I’d like to add a small display, order a custom PCB, and potentially even transcribe speech-to-text on-device.
