Sounds like a perfect recipe for a sand‑in‑the‑circuit problem, but I’m game – just don't let the beach sand get in the power rails, or I’ll have to rewrite the firmware from scratch again. Bring the solar panel, the toaster, and maybe a small bag of resistors, because you never know when you'll need a quick voltage clamp to keep the LED blinking at the right interval. And if you catch a cloud shape that looks like a circuit diagram, let me know, I’ll take a picture for my notes – they always look better with a little weather background.
