What it does

• 💬 Chats with memory — an LLM brain (DeepSeek by default, any OpenAI-compatible endpoint works) running on your PC; it remembers facts about you across sessions.
• 🎙️ Voice — hold a key to talk (streaming speech-to-text), and it talks back (TTS), all device-direct via DashScope. Push-to-talk up to ~1 minute.
• 🌆 A little life — it roams a "pixel holographic workstation" across 10 day/night scenes (studio / living room / bedroom / city / desert / grassland / ocean / snow / forest / space), switching indoor scenes by time of day, and reacts to your messages with moods.
• ⏰ Real info on screen — live clock, real local weather (open-meteo, auto-located), WiFi signal bars — animated continuously on the ESP32-S3's second core so it never freezes.

Tech

• Original Cardputer (ESP32-S3, no PSRAM). Firmware in PlatformIO (C++ / M5GFX).
• Node/Express "brain" on your LAN (keeps API keys off the device, holds memory).
• Device-direct voice (DashScope) + weather (open-meteo).
• Optional: run it alongside other apps via bmorcelli/Launcher (it's a normal app you can exit back to the menu).

The bundled character is an original generic mascot ("Pixel Buddy") — and it's a bring-your-own-character design: drop in your own 64×72 sprite sheets and it's your pet.
