Data Acquistion Using Bluetooth—World Without
Wires
by Mohammed Rana Basheer
The possibilities for Bluetooth seem endless. In
this straightforward project, Mohammed interfaced
an Ericsson ROK 101 007 Bluetooth module to an 8051
micro. If you follow his lead, you’ll soon have
your own wireless analog data acquisition and generation
unit. p.10

Interfacing with Frequency
Synthesizers
by John Teller
Designing
an RF circuit can be a difficult, time-consuming
endeavor. Interfacing to the hardware, on the other
hand, should be a breeze after you peruse this guide
to programming a synthesizer. John’s real-world
application will prepare you for a project of your
own. p.20

Vectorial Network Analyzer
byRobert Lacoste
Touting the use-value
of a vector network analyzer is an easy task for
any RF enthusiast. Coming up with a convincing reason
to purchase a VNA, however, is more difficult, especially
because they can be expensive and bulky. So, try
Robert’s do-it-yourself approach. p.24

world of Arm
by
Robert Martin
Now that you’re familiar with the world of ARM processors,
you should be thinking about how you can use the
ARM architecture in your own embedded systems. In
this article, Robert digs a little deeper and discusses
the ARM features that will reduce code size. p.36

Quad Bench Power Supply
by Brian Millier
The need for a bevy of equipment for building
and testing presents a problem: how to deliver
an adequate power supply while keeping workbench
clutter to a minimum. Brian decided to tackle
this classic engineering conundrum with a
small, low-capacity quad bench power supply.

A Low-Power Photoflash
by Tom Baraniak
There are many uses for a photoflash on a robot.
For instance, a photoflash can provide extra light
for your robot’s camera, or it can serve as a safety
strobe and warning beacon. Tom will show you how
to build a low-power photoflash strobe with an 8-pin
PIC micro. p.72
