The goal of our project was to create the motion of the hour hand of a clock using the vibrations from three speakers. |

You will build a horizontal circular platform that is actuated from underneath by three compliantly-attached voice coil actuators (i.e., speakers). The vibration of the platform causes an hour "hand" on top of the platform to slide around the circular platform, impelled by friction forces due to the vibration. If you bump the hand away, it slowly moves back to the correct hour. You may find other imaginative uses for your device. Check out this website to see more information on how this works and some videos of parts moving around a vibrated plate. |

Overview
The goal of our project was to create the motion of the hour hand of a clock using the vibrations from three speakers.
You will build a horizontal circular platform that is actuated from underneath by three compliantly-attached voice coil actuators (i.e., speakers). The vibration of the platform causes an hour "hand" on top of the platform to slide around the circular platform, impelled by friction forces due to the vibration. If you bump the hand away, it slowly moves back to the correct hour. You may find other imaginative uses for your device.
