BRL-CAD / STL Progress

30 05 2009

Shout out to Michael Davis. He read about my BRL-CAD STL problems and suggested I use combinations instead of regions. This largely fixed my STL export issues, and the export is generally much faster. I still have to check that a service bureau can use the STL files produced. Here is a render of the STL output:

You can see the faceting produced by the chosen resolution. Looks like we are back in business with designing and producing Polywell cores.

Now we have a book on the topic:

Very cool! Thank you Raymond Jimenez.





New Chamber

OK. The new chamber finally arrived along with the 8″ conflat blanks and gaskets:

Right off the bat we have trouble, a nick on the knife edge of the 8″ chamber conflat:

Today I’m going to assemble the chamber and pump, and see how low we can go despite the nick.

The next step would be to weld on a fresh conflat.

New Vacuum Chamber

Just won this smaller vacuum chamber. This should be suitable for a fusor experiment. I’m not giving up on the larger chamber yet, but I don’t want to lose momentum.





Gem Download Stats

8 05 2009

I’m a ruby/rails hacker and I like to keep up to date on the latest gems. This gem download stats page shows you what’s being used in the community. But it takes some effort to google each package individually.

So I hacked up a script which adds the first link/blurb from google. It’s not perfect, but it’s better than a static list. The excellent google-rest does the heavy lifting for my dirty hack. Enjoy!

Wolfram|Alpha

7 05 2009

Just noticed Wolfram|Alpha has launched. So far: 2+2 = FAIL. I imagine their servers are overloaded from the world’s curiosity.

I’ll reserve judgement until I actually get some answers back!

UPDATE: false alarm.
