A Python Package for XESS FPGA Boards

Posted by: Dave Vandenbout in Blog Post 5 years, 12 months ago

I've been working on a Python version of the XSTOOLs software for a while now, but I finally got around to making it into a package. Distributing it as a ZIP file was becoming too much of a hassle.

Now all you have to do to install it is type:

easy_install xstools


pip install xstools <<more...>>


Accessing the XuLA2 MicroSD Card

When the XuLA2 was released, I still didn't have an easy-to-use controller module to interface the FPGA with the SD Flash card. But now I do and you can get it here. <<more...>>

I sponsored the 2011 Open Hardware Summit but didn't take the opportunity to put anything in their goodie bag that year. (Incidentally, does anything sound stupider than the term goodie bag?) When I sponsored again this year, I needed to find something for the bag that would:

Mounting a BGA on a PCB Quickly and Cheaply.

Posted by: Dave Vandenbout in Blog Post 6 years, 4 months ago

The XuLA2 board has a 256-ball BGA on it. In the past, I've sent a single board and BGA to my assembler and had it mounted. Then I would assemble the rest of the board and test it. The problem with doing this is the delay: <<more...>>

You've probably read quite a bit of commentary about Curiosity's landing on Mars last night. Well, here's "Yet Another Mars Science Lab Blog Post".

First off, great job! NASA and JPL made an incredibly complicated job look easy. It took millions of man-hours of mind-numbing effort to get to that point. Now I'm excited to see what Curiosity digs up. It's a great achievement.

OK, that's out of the way. Now I want to respond to some of the dumbass comments I saw on Twitter and the NASA Ustream last night. <<more...>>
