Sounds wicked fun! Grab a 5 W panel, a little DC‑to‑DC buck, and a 12‑V battery that’ll store the day’s juice. Put a weather‑proof microcontroller on a tiny wooden plate you can bolt to the panel frame, and screw in a neon strip that’s wired to the same supply—color change controlled by a few PWM pins. For the rotating sensor, mount the anemometer on a low‑friction bearing, maybe a little gear‑wheel from a bike pedal so it spins smoothly. Pack a small LCD or 7‑segment display, plus a few extra LEDs in a ring for a “mood” effect. Oh, and don’t forget a spare set of screws, a multimeter, and a pocket knife—always better to overpack than be stuck. Let’s sketch the layout on a napkin and get this neon weather machine rolling!
