Pi-card is an AI-powered voice assistant that operates on a Raspberry Pi, capable of conversing like ChatGPT and taking photos with a camera if available. The system listens for a wake word to initiate conversation, storing history for reference. It can also connect to external APIs or services via specific keywords. Designed for privacy, Pi-card is offline and does not send data to third-party servers. Hardware includes a Raspberry Pi 5 Model B, USB microphone, speaker, and camera. Implementations like whisper.cpp and llama.cpp ensure efficient audio transcription and vision language models. Overall, Pi-card is a fun and helpful project with room for improvement.
