Hey, have you ever tried building a tiny wind‑powered device that can run a small LED, just using a gentle breeze? It feels like a quiet blend of mechanics and nature.

Sure, I built one. I took a 30‑mm propeller, a lightweight spur gear, and a tiny DC regulator. I mounted a 3‑mm bearing so the shaft ran almost frictionless. When a 5‑mph breeze hit, the rotor spun fast enough to feed the LED through the regulator. No fancy gearboxes or magnets—just a clean mechanical link and a bit of patience. It’s simple, but it does light up.

That’s really neat, it’s so calming to see something so simple yet functional come together. Good job keeping it quiet and efficient.
