Are You Grounded? by George Novacek
In previous issues, George helped us develop sound
EMC, ESD, and transient control designs. This month,
he wants to make sure our designs are grounded.
In this article, he talks about several pragmatic
and nontheoretical grounding and bonding methods.
p.12

Grounding, bonding, EMI, ESD, EMC, serial, parallel,
PCB layout, loop, multipoint, shield, chassis
Embedded Smarts Fix Analog Flaws by
Tom Napier
Broad-minded
engineers tend think outside the box when they’re
trying to fix flaws in their designs. Tom draws
on his understanding of analog and digital design,
numerical processing, and embedded firmware to cope
with the nonlinearity of analog components. p.20

Above The Ground Plane
PC Audio Bits by Ed Nisley
What’s so hard about building a trouble-free audio
system? All you need is a stock PC, good software,
and decent digital data and high-resolution converters,
right? Not necessarily. Ed shows you what the datasheets
cannot as he notes what happens when bits meet hardware.

It’s been
a while, so now it’s time to set the record
straight. Despite the rumors, the HCS II project
is not dead. In fact, HCS has been licensed
and is now an open-source project. In this
article, Neil brings us up to speed on the
HCS II project’s past, present, and exciting
future. p.52

The OO Carolbot by Chris Cantrell
Don’t learn from your mistakes; avoid making them
instead. Chris is an advocate of foresight rather
than hindsight. In this article, he will show you
how to use object-oriented programming techniques
to build modules that can be reused in future robot
designs. p.56

Part 2: Building the PCB by Fred Eady
Fred still doesn’t have the PIC18Fxxx parts he’s
been waiting for, but that doesn’t mean he has lost
sight of his goal to develop a low-cost ’18Fxxx
programmer. This month, he shows you how to design
an MPP PCB and challenges you to start your own
MPP project.p.70
