Lady Gaga's Keyboardist Designs
a Circular Piano
E
Who says a modern pi-
ano has to be a certain
shape? Not Brockett Par-
sons, Lady Gaga's key-
boardist. He worked with
Dave Starkey and Chuck Johnson to create Pi-
anoArc—a custom-designed 360-degree circu-
lar keyboard and a company with the same
name. I spoke with Brockett and Dave at Alti-
umLive to learn more about the design efforts
that went into this fascinating instrument.

Beyond Design: The Big Bang—
Lumped Element to Distributed
System
E
The simplistic approach to analyzing electron-
ic circuits is to use the lumped element mod-
el. However, in reality, that is not the case.
Barry Olney discusses the difference between
the lumped element model and the distributed
system.

Dana on Data: Creating IP-protected
PCB Design Rules
E
One of the primary reasons
that data packages aren't com-
patible is the fabricator/as-
sembler does not provide a
complete set of design rules
out of concern of giving away
their intellectual property (IP). Dana Korf ex-
plores the design rule development hierarchy
as well as what should be included in an IP-
protected design rule document.

The Shaughnessy Report: New Year's
Resolution—Get Involved
E
It's 2020, and it's time to hit the ground running as
we approach DesignCon and IPC APEX EXPO. If
you're not already networking with other design-
ers or volunteering in our industry organizations,
there's no better time to start. In the January issue
of Design007 Magazine, we give a special shout-
out to the volunteers who donate their spare time
to improving the PCB design community.
