4 Jennifer Huber	HTML Task Manager Tips and Solutions
8 John Gorsky	New Product News AD7400 and AD7401 isolated ADC from Analog Devices, Inc. ISPICR1 in-circuit programming adapter from OKW Electronics
9 David Tweed	HTML Test Your EQ
10 Alberto Ricci Bitti	HTML Wireless Monitoring System Alberto's MC68HC908-based wireless monitoring system is adaptable for use in domestic and industrial settings. The central monitoring station, which consists of a computer-controlled receiver with a relay output and LCD, logs and displays data from up to 20 different sensors. Read on to learn how to build, program, and test your own system. Download: Ricci Bitti_167.zip
20 Pete Rizun William Hue	Turbocharged Upgrade Crank Trigger Modification Eliminates Engine Knocking If you push a car with an aftermarket turbocharger too hard, its engine will knock. You don't need to be a trained mechanic to know that this puts stress on an engine. As a solution, Pete and William put a PIC16F73 and an MPX4250AP pressure sensor to work in a device that eliminates engine knocking without draining too much horsepower in the process.

28 Brad Thurow Joel Jorgenson Divyata Kakumanu Brian Morlock Mike Schmitz	Monopole Antenna Design Having trouble selecting an antenna for your new wireless system? Check out how this North Dakota State University design team used a guitar string antenna in a wireless sensor project. It's a great alternative to the expensive whip and surface-mount antennas that you're used to. Download: Thurow_Jorgenson_Kakumanu_Morlock_Schmitz_167.zip
32 Jennifer Huber	Renesas Design 2003 Contest Winners
36 Anders Rosvall	Simple Bluetooth Integration Part 2: Interfaces and ECI Protocol Last month Anders explained how the ROK104001 and cB-OEMSPA13i make Bluetooth integration a cinch. Now he covers the interfaces and ECI protocol. Bluetooth integration is in your future. Download: Rosvall_167.zip
44 Gareth Scott	ZRT Real-Time Operating System Gareth's small preemptive multitasking operating system runs on Zilog's Z8 microcontroller. The system -- which consists of lightweight threads, a round-robin scheduler, and a binary semaphore -- has the ability to voluntarily relinquish control back to the scheduler. Get ready to incorporate multitasking in your next project. Download: Scott_167.zip
48 Scott Pape	MCU Evolution New Microcontrollers Meet Increasing Demand Survival of the fittest? You bet. Scott describes two areas in which MCUs are evolving to meet the demand for cutting-edge apps: reduced power consumption and clock system flexibility.
Above the Ground Plane 56 Ed Nisley	Robot Mechanics Writing a program for a robot requires an understanding of both physics and standard programming techniques. This column contains all of the basic information -- essential formulas included -- every serious robot designer should know. Download: Nisley_167.zip
Applied PCs 60 Fred Eady	Adaptable Temperature Measurement System Fred recently designed a PIC18F452-based temperature measurement system for a small holding tank. Toss in a pair of Promi-SD202 Bluetooth modules, and you have wireless control. Download: Eady_167.zip
From the Bench 68 Jeff Bachiochi	Smart Sensor Design Designing smart sensors can be tricky. Back in the mid-1990s, members of the transducer community believed that the IEEE 1451 standard would make things easier. Has it? Take note of Jeff's opinion before starting your next smart sensor design.
72 George Martin	Designing with the Nios Part 1: Second-Order, Closed-Loop Servo Control Is the Nios the next major development in embedded system design? George is sold on its applicability; so much so, he used it to design a second-order, closed-loop servo control.
Silicon Update 78 Tom Cantrell	Radio Riot Wireless this and wireless that. With all the new products and standards floating in a sea of marketing hype, it's hard to know what will best fit your design needs. Fortunately, Tom's got the scoop on the most appropriate wireless solutions available to you, the designer.
