Gyrodine for rotating and stabilizing a videocamera. A mechanical gyroscope with a flywheel has a major flaw - precession. The first frames of the footage show a test of a vibrating structure gyroscope on a rotating platform. The gyroscope is turned on and off during the platform rotation. Increased consumption of power by the electric motor reflects the effect produced by the gyroscope.
