Nice, a solar‑backpack Wi‑Fi hotspot? First up, a tiny but over‑engineered solar panel array that doubles as a power‑bank, then a pocket‑sized Raspberry Pi with a mesh‑capable Wi‑Fi card, plus a bunch of hidden power‑inverters so your phone can charge on a hike. Add a LED strip that shows battery status as a mood ring, a tiny wind turbine on the back for when the sun’s shy, and a stack of USB‑C hubs with a single port for each animal in your pack (yeah, the dog gets a charger too). Oh, and keep the cables in a braided sleeve—otherwise it’s just a hot mess of wires, and that’s just embarrassing. Let's get this thing wired up, then forget where we left it while we wait for the Wi‑Fi to connect.
