10 Richard Wotiz	HTML Stealth Telephone Screener Mad Dash for Flash Cash Grand Prize Winner Tired of receiving bothersome automated phone calls from telemarketing companies armed with predictive dialing systems, Richard decided to fight technology with technology. The result? A PIC-based call screener that's been consistently successful at blocking unwanted automated calls. Download: Wotiz-156.zip
18 Tom Napier	A Minimal Flash PIC Programmer It's time to expand your suite of programming tools. In this article, Tom shows you how to use one of your old PICs to improvise your way to a minimal flash memory PIC programmer.
22 Brian Millier	Analog's New High-Flying DDS Family Thirty-five years ago, Brian commonly used LC oscillators to generate RF signals. But today the RF landscape is changing, particularly because direct digital synthesis (DDS) devices are poised to become regulars in high-end RF designs. This month, Brian describes his journey from LC to DDS and explains how Analog's AD985x family may change the way engineers approach their future RF designs.
32 Salvador Perdomo	Build a Three-in-One Measurement System MSP430 Desgin Contest Entry No home electronics lab is complete without a signal generator, logic analyzer, and digital oscilloscope. But why purchase the measurement devices separately, when you can build one system that houses all three? Salvador shows you how. Download: Perdomo-156.zip
42 Bert Korthof	Construct a Classroom-Friendly Evaluation Board MSP430 Desgin Contest Entry If you've been searching for an MSP430-based evaluation board, look no further. Bert built an inexpensive battery-powered board that even students and novices will find extremely easy to use. In this article, he walks you through the development process. Download: kortof-156.zip
Short Solutions 48 Richard Haendel	The Perfect PCB Prototype Richard holds the key to constructing perfect PCB prototypes. Are you interested? With this short solution, you'll learn how five simple steps -- print, mount, punch, fit, and evaluate -- can save a lot of time and money.
50 Jim Turley	Let's Get Small Code Compression Saves 32-Bit Chips Most major CPU vendors offer code compression because it has saved 32-bit chips from code bloat. Thus, it has nearly become a standard in most CPUs, which is great for consumers. But an important question remains: With so many companies offering comparable CPUs, can you choose one based on its compression system alone? The answer, you'll soon learn, is that you cannot. In this article, Jim explains why.
Embedded PC 58 Fred Eady	HTML Applied PCs Build a Coyote Protocol Converter To prepare for this month's column, Fred devoted a lot of time to thinking about an appropriate project for Z-World's Rabbit 3000-based Coyote. After mulling over plans for sprinkler controllers and water heater monitors, he decided to leave the brainstorming up to you. This month, Fred surveys the Coyote's capabilities in an effort to prepare you for future projects. Download: Eady-156.zip
66 Shlomo Engelberg Elyehoshua Shekalim	Spread Spectrum: Theory and Practice Understanding the science behind spread spectrum techniques could greatly enhance your next communications design. But comprehending the theory doesn't necessarily mean you'll produce a great product. Understanding this, Shlomo and Elyehoshua will help you bridge the proverbial gap between spread spectrum theory and praxis. Download: Engelberg & Shekalim-156.zip
72 Jeff Bachiochi	From the Bench D-Classifying Your Audio If you're the type of person who pines for amplifier efficiency and low THD, you may well be diagnosed as an audiophile. This month, Jeff -- a certifiable audiophile himself -- explains why he believes you shouldn't shun Class D amplifiers. To make his case, he focuses on Zetex's approach to "D-classification."
78 Tom Cantrell	Silicon Update What's the Buzz? What's ZigBee? And what's all the buzz about? Apparently, ZigBee is a fresh wireless standard, which, some industry analysts say, has huge market potential -- possibly greater than Bluetooth's. It remains to be seen whether there's any truth to such an assertion. In the meantime, let's take a look at what Tom thinks. As usual, he has the inside scoop.
