🧰 How to Turn Your Raspberry Pi Into an AI Agent

🧪 Step 1: Pick Your Pi (Model Matters)

• Recommended: Pi 4 or Pi 5 with at least 4GB RAM
• Older models may lag on AI inference
• Cooling accessories like fans or heatsinks help prevent thermal throttling

🧠 Step 2: Choose Your AI Framework

• Edge ML: Run local models using TensorFlow Lite
• Cloud Agent: Connect to OpenAI or Hugging Face for GPT-style capabilities
• Voice Assistant: Use Whisper + TTS engines like Coqui or PicoTTS

🛠️ Step 3: Tool Stack & Setup

Run these commands to install your AI tools:

sudo apt update && sudo apt upgrade
sudo apt install python3-pip portaudio19-dev ffmpeg
pip3 install openai speechrecognition pyttsx3

Optional extras: Docker, Node-RED, MQTT for automating smart devices

🗣️ Step 4: Add Voice Interface

Connect a mic and speaker, then use Python to capture input and respond:

import speech_recognition as sr
import pyttsx3

r = sr.Recognizer()
mic = sr.Microphone()
tts = pyttsx3.init()

with mic as source:
    print("Say something...")
    audio = r.listen(source)
    query = r.recognize_google(audio)
    tts.say(f"You said: {query}")
    tts.runAndWait()

🔌 Step 5: Automate Something Cool

• Control Zigbee or WiFi devices
• Use environmental sensors to trigger alerts
• Pull calendar updates and system status
