I Built an AI Video Factory on a $35 Raspberry Pi (It Runs 24/7)

I wanted a YouTube channel. I hated editing videos. So I built a machine that does it for me.

What It Does

AI Video Factory is a fully autonomous video production pipeline. It:

1. 🧠 Researches trending topics
2. ✍️ Writes a professional script
3. 🎨 Generates 1080p slides with dynamic gradients and typography
4. 🎵 Adds background music
5. 🎬 Assembles everything into a polished video

All without a single human click. It runs on a cron job — every morning at 7 AM, a new video is ready.

The Stack

# The entire pipeline fits in one Python file
from PIL import Image, ImageDraw, ImageFont
import subprocess, json

# 1. Research topic (Bing API)
# 2. Generate 8-10 slides with Pillow
# 3. Assemble with FFmpeg
# 4. Ready for YouTube

What makes this different:

• 💰 $35 Raspberry Pi — no AWS, no cloud GPUs
• 📦 Python stdlib + Pillow + FFmpeg — zero exotic dependencies
• ⏰ 24/7 cron automation — set it and forget it
• 🌍 Offline-capable — no internet needed for rendering

Why I Built This on a Pi

Everyone told me: "You need a $200/mo cloud server to run AI video generation."

I proved them wrong. A $35 Pi sitting under my desk handles everything: topic research, script writing, slide generation, video assembly. The entire stack costs $0/month to run.

What I Learned

1. Python stdlib is underrated. You do not need FastAPI, Docker, or Kubernetes to build real products.
2. Cron is the best scheduler. Simple, reliable, zero-config.
3. The best product is the one that runs itself. I was sleeping while my Pi made this video.

This Is Part of Something Bigger

AI Video Factory is one of 23 AI products I'm running on the same $35 Raspberry Pi. All open source. All 100% automated.
