Hypotrochoid
A hand-cranked spirograph that uses LEDs to trace hypotrochoid patterns.
Materials: Aluminium, wooden dowel, synchronous belt and pulleys, bicycle wheel hub, nylon gears.
"Gizmo": a project set by the Innovation Design Engineering department at the Royal College of Art and Imperial College London, that challenges its first-years to build a contraption consisting of at least 5 mechanical elements.
My gizmo creates hypotrochoids: a family of mathematical curves generated by taking the centre of rotation of a spinning stick, and moving it in a circular path as it spins. 30 seconds of video below explains this rather more succinctly:
