Wind turbines are a great source of renewable energy, and a great DIY project, too. They can be built with all kinds of materials and the barrier for entry is low for the beginner.

 .

[Fab] has built just such a device, taking advantage of modern construction techniques, and dubbed it the WinDIY. The WinDIY design is mostly 3D printed, with a familiar three-bladed design. The diameter of the rotor is 1.2 m, meaning that braking and regulating the turbine is required for safety in high winds. [Fab] is aiming to achieve this control with a combination of mechanical and electronic braking, as well as variable-pitch blades. The benefit of 3D printing the design is it allows iterations to be made quickly, particularly of parts with complex geometries that would be too time-consuming or expensive to machine otherwise. [Fab]’s writeup goes into great detail on topics like the design of […]
