A Hoberman Sphere is a structure invented by Chuck Hoberman that resembles a geodesic dome, but is capable of folding down to a fraction of its normal size by the scissor-like action of its joints. Colorful plastic versions have become popular as a child's toy.
Typically it consists of six great circles corresponding to the edges of an icosidodecahedron. The Hoberman Sphere can be unfolded by allowing certain members to spread apart.
Jason Alleman [1, 2] built a motorized spinner stand for his LEGO Hoberman Sphere.
By speeding up and slowing down the rotation of the Hoberman Sphere, it expands and collapses on its own.
Here you can find the link for the original photos at Jason's flickr photostream, and you can also find the building instructions for the sphere, through this page at Rebrickable.
Please avoid sending requests to post specific models on this TBs section.
We understand some of you would enjoy to see your creations featured here, but please understand that because only one video gets highlighted per week, it is impossible to accommodate all the great MOCs continuously build by the Technic builders out there. They simply won't fit all and that's also not the purpose of this blog (see the header statement).
Many of your MOCs are scanned anyway and listed for later publication when they do not fit immediately. However some remain in the backlog queue just for too long and eventually loose the relevance or the publication opportunity window. As a rule of thumb, we also avoid publishing MOCs that have been featured by their authors or other fans at some other great web places dedicated to the Technic community out there. It doesn't mean that occasionally some won't get published here anyway.
Thanks for your understanding!
