Apertua™ was inspired by the aperture mechanism found in camera lenses. The aperture can be operated in two different ways, either manually or powered by an Arduino Uno micro-controller board. We made a lever which allows the 22 arms to rotate the flexible aluminium blades to open the aperture.

The aluminium blades are made by etching. The design of the blades were generated using a 3D-modelling software to ensure smooth movement as they pan and slide across one another when the outer gear is rotated.
