Hoberman Spheres Using Lego Technic Parts
Posted 21 May 2010 - 02:35 PM
Several LEGO fans have attempted to replicate the Hoberman design using LEGO Technic parts:
1) Akos Kostyan built a "Magic Sphere Ball" with enough step-by-step photos to make your own ( http://www.mocpages.com/moc.php/5599 ):
2) Jason Allermann has this version which he displayed at Brickfest 2006 ( http://www.brickshel...y.cgi?i=1990798 ):
3) Inspired by Jason Allermann's design, Barman made this colorful interpretation ( http://www.brickshel...ry.cgi?f=245253 ):
Maybe its possible to MOTORIZE the opening/closing action via Power Functions. Perhaps you could use the entire range of TECHNIC colors, and make a Hoberman Sphere that looks like Chris Behren's Color Wheel ( http://www.brickshel...ry.cgi?f=431972 ):

On his Flickr photostream, True Dimensions recently posted the picture shown below and a Flickr video of a motorized Lego Hoberman Sphere mechanism that opens and closes the assembly. Centrifugal force makes the sphere expand, then collapse under its own weight when it slows down. True Dimensions wrote,
"Hoberman Sphere Spinner - Video
Although the Hoberman sphere is pretty stable, it can't really take the repeated abuse of being handled by the public at a show.
I built the spinner so that I didn't have to stand around and open and close it myself, or keep putting it back together.
It works really well when connected to a programmable controller to repeatedly start and stop it."
Here is the closed Hoberman sphere and open sphere:
