Cue Watch, a voice-first AI smartwatch on a Waveshare ESP32-S3
A parent and son vibe-coded a voice-driven reminder and notes smartwatch on a Waveshare ESP32-S3 AMOLED board using Claude Opus.
The full story
A father and son vibe-coded Cue Watch with Claude Opus: a smartwatch on a Waveshare 2.06" ESP32-S3 AMOLED board that works as a voice assistant for events, reminders and notes. The firmware uses ESP-IDF and LVGL, and a cloud backend handles speech-to-text, a language model and text-to-speech.
The hardest part was keeping the microphone timing stable while updating the display. They added an offline queue on the SD card so voice commands survive if Wi-Fi drops during upload.
