Remote Health-Monitoring
System
PSoC Design Challenge 2002 Winner
by Victor Kremin
The
uses for Victor’s award-winning health-monitoring
system are endless. Rehabilitation technicians,
athletic trainers, and emergency-response crews
would all benefit from having his portable monitoring
system on-site. In this article, Victor describes
what he was shooting for when he started the design
and explains how he built the system. p.10
Keywords:
PSoC2002,
PSoC, health, ECG, pulse, acceleromater, heart rate,

ROBOTICS
CORNER
The Altmotor
by
Christopher Dix
Most robotics projects require powerful,
high-torque motors. Understanding the need for such
a motor but unwilling to spend the cash on one,
Chris built his own variable-speed motor. If you
think it was a complicated project, think again.
All it took was a little imagination and the alternator
in his wife’s van. p. 18
Keywords:
Robotics, alternator, stepper motor, power, construction,
armature, rotor, torque, unipolar, bipolar, driver,
sequencing, chopper, ispPAC-POWR1208

Construct
a Hand-Held Radiation Monitor
by
Mikhail Galeev
If you’re a safety-conscious homeowner, then you’ve
probably equipped your house with safety devices
like smoke detectors and burglar alarms. But shouldn’t
you also protect yourself from radiation? If you’re
interested in doing so but don’t want to spend a
fortune on a machine, then you can follow Mikhail’s
instructions and build your own. p. 30
Keywords:
Radiation monitor, portable, Geiger-Muller,
GM, LCD, serial, alarm, MSP430, C

Battery Power
Feeding the Z3801A
by Ed Nisley
After purchasing a Z3801A GPS receiver, Ed decided
that he wanted to play a more proactive role in
controlling the device’s diet. To do so, he set
out to design the perfect battery charger. He ended
up with an effective compact power trough for his
receiver. p. 46

Time-Triggered
Technology
by
George Novacek
Clearly, the older communications protocols used
by the aerospace industry are becoming increasingly
expensive to implement. But, as George explains,
change is on the horizon in the form of TTP technology,
which may soon become the inexpensive solution for
your future applications. p. 50

it Now!
by Fred Eady
Despite the references
to force fields and spaceships, you’ll soon
learn that building a Z8-based e-field EVM
is neither science fiction nor rocket science.
In fact, it’s a fairly straightforward, uncomplicated
process—just how Fred likes it.

by Tom Cantrell
What do the Beach Boys, B-movie aliens, and Motorola have in common?
They all owe some of their varied successes
to the science developed by a KGB bug maker
named Leon Theremin. In this column, Tom connects
the technological dots by way of an introduction
to the MC33794 and e-field technology.
