Ever wondered how the tuning fork mechanism works: The two thin copper wired coils (80 meters each) are battery powered through transistors. The magnetic fields around the edges of the coils on the tuning fork create a vibration that brings the index wheel in motion, by generating a magnetic field of attraction and repulsion. The vibrations cause the tiny 2.40 Ø index wheel with a whooping 320 teeth to move, or rather hum. The vibrations have a frequency ranging between 300 and 700 Hertz.
Tuning fork mechanisms are much better equipped against external influences, such as gravity. Looking back it seems uncomplicated and straightforward, but for those days the use of tiny transistors was like something from outer space.
Are there any ‘Spaceview’ lovers out there? Here’s your chance to hum away 😉.
