Lighthouse Tutorial (Zen Magnets)

This video shows how to use 10,650 Zen Magnets to build a lighthouse, a double-walled tube invented by Damian O'Connor (   • Perfect 2 layer Neocube Cylinder  ) supporting a snub ball of my own invention (   • Snub Ball Tutorial (Snub Dodecahedron, Zen...  ). For photos of the lighthouse lit from within, see my Flickr photo stream, http://www.flickr.com/photos/91128546....

Each of the 51 rings in the tube requires 80 magnets, for a total of 4080 magnets. Removing 20 magnets from the top end of the tube reduces the tube magnet count to 4060. Tubes can be built using my fast technique (   • Double-Walled Tube Tutorial (Zen Magnets)  ).

The sphere is a snub ball of edge length 5, first built by Jonathan Minond (   • L5 Snub Ball - (Snub Dodecahedron)  ). A complete snub ball requires:
60 vertex pieces made of double hexagon rings
150 edge pieces made from double rings of 10
80 triangular faces made from double rings of 9
12 pentagonal faces with 130 magnets each.
This requires 60*2*6 + 150*2*10 + 80*2*9 + 12*130 = 6720 magnets. Omitting one pentagon (where the ball attaches to the tube) reduces the snub ball magnet count to 6590.

The total magnet count for the lighthouse is 4060 + 6590 = 10,650.
