used a servo to jitter the wings which would fail every 3-6 months and work intermittently. I
designed a new wing flapping mechanism within the existing sculpture, creating an apparatus
similar to a rod puppet. The wings are attached to two axes which are yoked to a down rod. The
down rod connects to a stepper motor underneath the platform which is controlled by an
arduino connected to a vibration sensor. The code varies the speed and number of the wing
flaps, giving a random motion each time the Dragonfly is triggered by a guest knocking at the
glass.
