by Pete Cross
Will the ZigBee standard successfully emerge from the world of
technical committees and marketing hype? If
so, will it be accessible enough for you to
use in simple low-cost projects? In this two-part
series of articles, Pete investigates these
questions and more. p. 16

Minimum
Mass Wireless Coupler
Dick
Cappels
Dick’s
minimum mass wireless coupler allows you to connect
the devices on your workbench to a PC. No electrical
connections are required. You can use an AT90S2313
or an ATmega8 to control the system. p. 24
Keywords:
RF, wireless, AT90S2313, coupler, carrier, antenna,
frequency meter

Noncontact
Infrared Thermometry
Brian
Millier
Noncontact
infrared thermometry has enabled doctors to get
rid of mercury thermometers. This technology also
allows distributors to monitor the temperature of
food products without contaminating them with sensors.
Read on to learn how to use it in a project of your
own. p. 30

by Bryan
Sobczyk, Vince Formica, William Sebastian,
& Kevin Wertz
This
group of former University of Akron students
built a wireless telemetry system for a racing
team that needed a way to obtain real-time
data about its car’s performance. The result
is an affordable system that’s perfect for
industrial control and data acquisition designs.

Capacitors
at RF
Ed
Nisley
Sometimes you have to watch out for the little guys—you
know, the simple capacitors you overlook as you
focus all your attention on microcontrollers and
sensors. Neglecting the least glamorous parts of
a design can come back to haunt you, especially
if you’re working with high-frequency circuits.
It’s time for a closer look at capacitors. p.

Keywords:
Capacitor,
RF, high frequency, reactance, inductance, lead
lengths

Source Code Guide
Elecia
White
Writing
code from scratch isn’t always practical, especially
when time isn’t on your side. So before you start
working on your next project, take a look at Elecia’s
approach to code collection. Working with free code
can cut in half the time you’d otherwise spend on
the software end of a project. p. 68

XTstat:
A Portable Wireless X10 Thermostat
Henry
Jacobs
Henry’s
XTstat wireless thermostat allows you to adjust
a room’s temperature with a remote control. Inexpensive
and easy to assemble, this PIC12F629-based device
is a great starting point for wireless temperature
control projects. p. 56

UPDATE
More Bits, Less Bucks
Tom Cantrell
Tom’s saying it again: 32-bit ARM-based MCUs are
poised to become the 8051s of tomorrow. This means
they are quickly becoming a practical option for
embedded designs. But the story isn’t just about
performance; it’s also about price. And the price
seems right. p. 80
