VoiceNotes is an Arduino sketch for the Waveshare ESP32-C6-LCD-0.85 that
records meetings and voice memos to microSD and turns them into notes:
- Records 16 kHz mono WAV (up to 4 h) from the ES7210 dual mics, with a
boosted preamp and soft-limited digital gain
- Transcribes via an OpenAI-compatible speech-to-text API in ~10 min parts
cut at quiet points, with retries and resume after failures
- Summarizes the transcript with Claude into meeting notes (decisions,
action items, topics with timestamps), streamed to and from the card
- Copies the notes to Nextcloud over WebDAV
- Shows recording/processing state on the 0.85" LCD and the LED ring
- Works around the board's SD card failing multi-sector reads
Credentials live in VoiceNotes/secrets.h, which is git-ignored; see
secrets.example.h.
Also adds the Microsoft CDM customer service SQL implementation (DDL,
sample data, reporting queries and docs). Its README is renamed to
CDM_README.md so the repository README stays at the top level.
