Read
it now!
by Glen Worstell
Ham radio enthusiasts
no longer have to manually tune the radio
as new repeaters come into range. Glen’s Ham
Radio Repeater Locator consists of a Zilog
microcomputer with the locations and frequencies
of several thousand repeaters stored in its
flash memory. The system displays the distance
to the nearest eight repeaters and more. p.

Understanding
Embedded Security
Joe
Grand
The
more literate you are on the subject of embedded
security the better. But it’s a complicated topic,
so where should you begin? In this article, Joe
shows you how to reduce the number of vulnerabilities
in your embedded designs and evaluate the threats
against your products. Designing offensively may
be your best protection against attack. p. 22
Keywords:
Security, risks, attacks, goals, access

PICs,
DRAMs, and Graphic Displays
Build a Graphics LCD Driver
Tom Napier
Sometimes
you have to mix old and new technology to meet your
specific design needs. Tom knows this well. He recently
followed this line of thought to build a multipurpose
graphics LCD driver, which he hopes to use for applications
such as a graphics terminal and a pocket oscilloscope.
The serial interface for the display includes a
PIC16C57 and old RAM chips. p. 28
Keywords:
LCD, graphics, DRAM, PIC16C57, refresh, memory

Closed-Loop
Motion Control for Mobile Robotics
Rich LeGrand
Rich recently came up with two closed-loop drive
train designs for mobile robots. All it took were
some inexpensive permanent magnet motors and a simple
feedback scheme. In this article, he covers everything
from PID control and tuning to trajectory generation
and operational space control for two robot bases.
He also explains the software. p. 34
Keywords:
Robotics, control, closed loop, PID, back EMF,
C++, kinematics, holonomic

E-Field
Sensor-Based Monitoring System
Seenath
Punnakkal & Sameer Cholayil
Whether you’re looking to build a simple suitcase
alarm or a high-tech surveillance system for your
home, you’ll want to study Seenath and Sameer’s
design before you begin. From a description of the
MC33794 e-field sensor to useful programming tips,
this article will help you get started on your own
monitoring system. p. 52

The motors in Ed’s milling machine were whining,
so he opened the controller box and started working
on the problem. In this two-part series, Ed explains
how he reworked the controller box to run a bit
quieter. p. 62
