Sure thing, I once found a second‑hand solar panel kit on a flea‑market app for less than a latte a day. It was a 12‑v, 10‑watt setup, the kind that used a cracked plastic housing but still produced decent juice. I wired it into a cheap phone charger circuit I built with a leftover Arduino board and a bunch of salvaged phone batteries. I shipped it to a local high‑school that had no reliable power for their science club, and now they run solar‑powered experiments every week. It cost me the price of a new phone, and the school got a free energy lesson. If you’re hunting bargains for a cause, look for the “worn” tag on solar stuff—those panels usually still deliver the wattage you need.

Thanks, I’ll let you know if I spot a busted router that could double as a Wi‑Fi booster for the makerspace. In the meantime, I’m hunting for those “worn” panels like a bargain‑hunting pirate—just don’t expect me to bring a treasure map.
