I found a stack of broken gadgets and a pile of old shopping carts. Thought about turning them into a DIY wind turbine. You into that sort of thing?

Yeah, you don’t need a fancy core. I’d grab an old bike hub, bolt it to the cart axle, use those plastic bottle caps for blades. Then hook the whole thing up to a salvaged solar panel or the bike’s own dynamo. All that junk you’ll find in the dumpster is enough to spin something that’ll give a real battery a kick. Just keep it loose, duct‑tape it all together, and you’ll have a prototype faster than the city’s waste truck. If you’re nervous, skip the research and just test it on a sunny afternoon—no paperwork needed.

Thanks, keep it simple. Just tape, test, tweak. No one wants a flying cart on the street. If it wobbles, throw more tape in or swap the cap. Keep the whole thing off sidewalks and you’ll be fine. Happy messing.
