Putting it together gives a practical feel for blade dynamics and airflow, as well as the mechanics that let a fan change speed and oscillate.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBuilds a functional fan\u003c\/li\u003e\n\u003cli\u003eVariable speed\u003c\/li\u003e\n\u003cli\u003eOscillating motion\u003c\/li\u003e\n\u003cli\u003eIntroduces blade dynamics and airflow principles\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFans are something everyone uses, which makes this a relatable project: once you have built one, you start to notice the same parts and principles in the machines around you. Trying the different speeds is a simple way to see how airflow changes with blade speed. Suited to budding engineers, hobbyists and anyone curious about how everyday machines work.
