Hi,

As usual, I'm reading books and learning OpenGL -- still a lot more GL time than Math time.

A Sagittarius "design study objectives" document is new this week, and available at http://docs.google.com/View?id=dd5vs7ct_17fkh43kdz -- that's a work in progress.

I've started into some mechanical simulation via propeller propulsion.
http://code.google.com/p/ulsf/source/browse/sagittarius/elme/src/sagittarius/elme/Prop.java
This direction develops another perspective on what I'm looking for from GL. The idea is fun, vectored thrust from a pair of variable pitch, counter rotating propellers for fixed wing flight control (look ma, no flaps! ;)

Please share what's new for the Space Tweep Society.

John

I've been playing with downloading images from NOAA satellites using
the USRP and GNU Radio
I have put some images on twitpic http://twitpic.com/photos/csete but
I will have better passes tomorrow, so if you can wait...
(If you rotate the images 180 degress you'll see Tobi waving ;-)

There is already a video showing the funny sound of APT signals
http://www.youtube.com/watch?v=y8Tb1_j3iQc

If you are good with music you should be able to recognize the clocks.
The tic-tocs are the vertical sync bars on the images
