Show HN: Look Ma, No Linux — Bare Metal ESP32-S3 🦾

Linux runs everything these days. Servers, phones, smart toasters. So when someone builds a complete OS without Linux, people notice. Meet BreezyBox — a shell, app installer, text editor, and C compiler running bare metal on a $10 ESP32-S3 chip. 🦾

The ESP32-S3 is a tiny microcontroller, not a full computer. Yet this project squeezes an entire operating environment onto it. No Linux kernel. No POSIX layer. Just pure, optimized code talking directly to hardware.

What it includes:

• 🖥️ Custom shell with basic commands
• 📦 App installer for adding programs
• 📝 Vi-style text editor
• ⚙️ C compiler (yes, really)
• 🎮 Runs on $10 hardware

This is more than a novelty. It proves that modern software bloat is a choice, not a requirement. A complete computing environment in kilobytes, not gigabytes. The efficiency is almost offensive to contemporary developers.

For Gen Z makers, this is inspiration. You don't need expensive hardware or complex stacks to build something amazing. A cheap chip, some creativity, and bare metal coding skills — that's all it takes.
