My Magnetic Spin Toy Prototypes
Channel: Jon Bondy
Date: 30/12/2011

I built some magnetic spin toys by cutting disks out of a plastic sheet, gluing magnets onto the circumference, inserting a brass tube through the center of the disk, and suspending the disk on a brass shaft using two opposing (repelling) magnets.  The patent for this concept may be found here: http://www.pat2pdf.org/pat2pdf/foo.pl?number=5135425. For more information about this project, see http://jonbondy.wordpress.com
