What do you want to do?

4 use cases

  • Flash a wake-word voice assistant onto an ESP32

    Flash the QuickSilver preset so the gadget answers out loud after you say Hi, ESP.

    View prompt
    In the esp32-thinks repo, run the quicksilver preset setup against the SDK at <sdk-path> on serial port <port>, then report whether the build and flash finished without errors. Verify that the device answers after you say Hi, ESP or press the knob.

  • Route speech, chat and TTS to different AI servers

    Point each of the three endpoints at a different OpenAI-compatible server using the custom preset.

    View prompt
    In the esp32-thinks repo, apply the custom preset with separate STT, chat and TTS endpoints for <provider-list>, then confirm the generated provider config lists three different base URLs. Verify by running a typed probe with python3 scripts/tts_probe.py /dev/ttyACM1 "hello?" and checking that a reply is produced.

  • Give the voice assistant memory, weather and clock

    Run the in-repo openmuse agent so answers know your location, time, weather and past notes.

    View prompt
    In the esp32-thinks repo, start the openmuse agent with ./openmuse/run.sh --funnel after setting UPSTREAM_API_KEY and OPENMUSE_TOKEN in openmuse/.env, then report the public HTTPS URL. Verify the agent responds to a chat request and that memory is written to openmuse/data/memories.json.

  • Test chat and speech on the device without a mic

    Run typed turns over serial to check the chat and TTS pipeline before a voice test.

    View prompt
    In the esp32-thinks repo, run python3 scripts/tts_probe.py <port> "hello?" against the flashed device and report the chat reply text and whether speech was produced. Verify that the probe finishes without a stall and that >status shows Wi-Fi and heap healthy.
