## Wiring Diagram

22 02 2009

So I’m working on an algorithm to come up with a wiring diagram for the dodecahedral core. It’s more complicated than just wiring up the 12 coils in series. This is would only magnetically protect 12 of the 30 connecting joints. Ideally each join would get one pass of superconducting cable. A picture to meditate on:

Lets start by making some methods to traverse the net. Currently I have this functionality:

Geometry::Dodecahedron.faces.first

=> [Vector[1, 1, 1], Vector[1, 1, -1], Vector[0.618033988749895, 1.61803398874989, 0], Vector[1.61803398874989, 0, 0.618033988749895], Vector[1.61803398874989, 0, -0.618033988749895]]

So I can easily iterate through the the faces, and I get the vertices of that face unordered. The first challenge is to order these collections of vertices so that you traverse the face clockwise simply by iterating the collection.

## Vacuum Chamber

I’m watching this auction for a vacuum chamber. It weighs 653Kg (1440Lbs). Big and Heavy. I checked fedex rates, it would cost a minimum of \$2,000 to ship this beast. More than the chamber. Maybe it can be uhauled for less: Road Trip.

MSimon, this thing is near you.

## Chassis Cutaway

I built this cutaway version of the chassis so we can do a fit and finish test with superconducting cable without spending a wad of money.

## New Arrivals

Just in: An eeePc and replacement water pumps for the laser from Hong Kong. I got the eeePc because I wanted a dedicated Ubuntu machine. I couldn’t get Ubuntu installed on my old mac. I’m going to see if I can now get the reprap host software running. Also going to try installing SciLab.
