Hi all,

I've been working on a small board for scientists (and artists) that
runs Python. The idea is to make something like an Arduino, but beefed
up to handle real web traffic. Some background on the board at
http://www.engadget.com/2012/06/13/rascal-micro-hands-on-video/ and
more at http://rascalmicro.com

I'm shipping boards with scipy and numpy preinstalled, and I'm
wondering what other libraries complement those two well. I'm aware of
(and actually have a library of my own listed on) the list at
http://www.scipy.org/Topical_Software but it's hard to tell what's
both mature and widely used.

What are the top 3 or 4 libraries you use, either for control during
experiments or for data analysis?
