Here are my pricision workplans for building your very own ball spinner on the cheap.  Knowledge of centrifugal compression and metric hyper-diodes are the only tools needed.

Warning... not for those who are not good with their hands or afraid of complex mathematical algorithms.  Some degree of science is recommended before attempting this kit.

After trying it yourself, please post your results for the world to see!

Best of luck!
