[OH Updates] diluting your list of Open source products

I don't think the worth of an OSHW project is set by how technically
ambitious it is but rather by the degree to which it enables people to
do useful and/or cool things. For example, the gyro breakout boards
that Sparkfun sells have made it much easier for hackers and other
hobbyists to use MEMS gyros in their projects. And that enables things
like DIYDrones and any number of balance bots to exist. The OSHW
ecosystem needs to include a lot of very simple, cheap, and useful
boards as well as meatier projects like the Ardupilot or Dangerous
Prototypes' excellent tools.

Far from setting a good example for OSHW, I don't think Ettus products
even qualify as OSHW under the the OSHW 1.0 definition. Their software
certainly qualifies as OSS, but their hardware fails to meet core
provisions of the OSHW 1.0 definition. Specifically, Ettus fails the
documentation requirement. They publish schematics as pdfs (i.e. the
moral equivalent of compiled code), and so far as I have been able to
determine do not publish their board layouts in any
form whatever. Since layout is at least as important as schematics for
high speed and RF boards (most Ettus boards are both), that means they
do not supply sufficient information for others to duplicate and/or
learn from key aspects of their work.
