Richard with his Gyroscope

Richard brought his steel gyroscope to the Bristol Hackspace the other evening. It's powered by a brushless DC motor of the type normally used in model aeroplanes. The motor controller is not set up for a load with such high inertia, because it very rapidly assumes that the motor is jammed and stops driving it. We spun up the gyro with a pull-cord to get it started and then gradually worked the motor controller up to keep it spinning, and then to accelerate it. The highest speed, according to the laser optical tachometer, was 11,000 RPM.
