A system of strongly coupled multiple Yo-Yos in series is disclosed in which very string that connects the successive Yo-Yos may be wrapped around Yo-Yos respective axles and therefore can be wound or unwound on both ends at the same time. Accordingly, both ends of the strings and their respective Yo-Yos may move with different speeds and accelerations. Yo-Yos in the system have a modular structure. The system also can be constructed with modular pieces to provide different operating modes when is set in motion. In embodiments, the Yo-Yos may be connected via the return strings. To ensure the Yo-Yo sides remain with equal length during the operation, a regulating mechanism is provided, and a regulating ring to keep the two sides of the return string in proximity, and assuring a long operation.

A nested counterweight for a rotatable performance device includes an outer housing and an inner slider. The outer housing defines an interior volume and is configured to be positioned along a string of the rotatable performance device. The inner slider is also configured to be positioned along the string of the rotatable performance device. The inner slider is positioned within the interior volume on the outer housing in a nested configuration. The inner slider is positioned along the string away from the outer housing in a separated configuration.

A yo-yo having improved spin time is disclosed. The yo-yo has a body comprising two side members joined together at their centers by a fixed axle. A yoke for receiving a string in winding relation is magnetically supported for substantially frictionless rotation about the axle. A pair of radially-magnetized ring magnets disposed at opposite ends of the yoke are received within a corresponding pair of radially-magnetized ring magnets disposed within recesses in the side members. A pair of axially-magnetized ring magnets disposed at opposite ends of the yoke confront a corresponding pair of axially-disposed ring magnets set into the body side members. The magnets are magnetically polarized such that they mutually repel each other. As a result, the yo-yo is free to spin around the yoke for an extended period of time.

There described a computerized yo-yo toy that uses an acceleration measuring device, a computation and control device, a communication device and an electric clutch device to effect the motion of the computerized yo-yo toy. The acceleration measuring device measures the acceleration values of the computerized yo-yo toy. The computation and control device uses the measured acceleration values to generate control signals to the electric clutch device. The electric clutch device creates or eliminates friction with an outer case of a ball bearing, based on the control signals, to affect the motion of the computerized yo-yo toy. The communication device receives setup parameters from an external device and transmits the setup parameters to the computation and control device. The computation and control device may further generate the control signals to the electric clutch device based on the setup parameters.
