A slowly turning brass windmill with three glowing filament blades. Speed knob, USB-C charging and a wooden base. Get it built, or solder it yourself from the kit.
Free step-by-step build guide included.
Three warm LED filaments spin on a hand-soldered brass tower. A small geared motor turns the blades, the speed knob sets anything from a lazy drift to a fast spin, and the built-in battery runs it for hours away from the cable.
