6 Jennifer Huber	HTML Task Manager Reliable Information
8 John Gorsky	HTML New Product News PC104-ELC 16-bit 10 Mbps PC/104 Ethernet card from Radicom Research, Inc. Model 869 universal device programmer from B&K Precision Corp. SUM110Nxx and SUM85Nxx TrenchFETs from Vishay Siliconix Easy Input keyboard emulator IC from Radovan Robotics PPCI7443 four-axis motion control card from Nippon Pulse Motor Co., Ltd.
11 David Tweed	HTML Test Your EQ
12 Aubrey Kagan	HTML Driving the NKK Smartswitch Part 1: Configuration and Software Sure, the NKK Smartswitch looks like a cool device, but how can you actually use it? Aubrey found the answer with a little help from a Cypress Microsystems PSoC microcomputer. In this article, Aubrey describes the interface to drive the Smartswitch.
20 Brian Millier	Short Solutions Build a Graphics LCD Bias Supply, AVR MCU-Based AC Phase Controller When Brian proposed these two straightforward, simple fixes, we thought it was a great idea to combine them as a section of quick solutions. Read on for inexpensive ways to control a high-current resistive load and how to build a graphics LCD bias supply with Atmel products. Download: millier 144.zip
24 Noel Rios	HTML An 80C31-Controlled Power Supply Even if you're a novice, it's pretty easy to control the power supplied to the circuits you're working on. In this article, Noel introduces us to a 80C31-controlled power supply, which is a circuit that enables you to monitor and alter voltage and current levels. Download: rios 144.zip
30 Sonny Lloyd	Extreme OSMC Part 2: The Modular OSMC Brain Last month, Sonny taught you how the OSMC board functions. Now he's going to show you an inexpensive way to assemble and use a Modular OSMC Brain, which is a controller that uses the signals from a radio control receiver to drive OSMC boards.

34 George Novacek	Taming the Transients Transients, such as electrostatic discharge and lightning, can create major problems for many of your electronic designs. However, there are several ways to limit the component damage and functional upset that results from transient exposure.
42 Peter Chia	LCD Controller for a PIC Peter uses PIC parts in many of his projects, but there are times when he would prefer to be able to display PIC info on an LCD panel rather than on segment displays or LEDs. In this project, he shows us a simple way to build an LCD controller for a PIC using few parts.
Embedded PC 46 Fred Eady	Applied PCs Building a Modular Programming Platform, Part 1: The Program Module Fred is dreaming of producing an inexpensive PIC18Fxxx programmer that will ultimately allow him to use the new PIC parts in future PIC Internet/Ethernet projects. With the datasheet and programming specs in hand, he takes us through the first part of his project. Download: eady 144.zip
52 Joseph Jones Ben Wirz	RoCK Specifications Part 4: Tying Up Loose Ends In Parts 1, 2, and 3, Joseph and Ben discussed the RoCK's specifications, circuitry, and programming. In this final part, they'll describe its discrete motor driver, explain the RoCK/host interface, and show you how to create a new user-programmed task.
60 Ross Bannatyne Dave Wilson	Dealing With Motor Control Dead-Time Distortion Dead-time distortion can be problematic when you're trying to design a motor controller. But that doesn't mean you have to settle for noisy, rough-running motors. Ross and David explain there are inexpensive enhanced microcontrollers that can correct distortion.
66 Jim Turley	Starting Down the Pipeline Part 2: The Long and Short of It Long pipelines are needed to reach higher clock frequencies. However, longer pipelines aren't necessarily better in the complicated world of microprocessors. For insight into the issue, read Jim's explanation of the pros and cons of processors with long pipelines.
70 Jeff Bachiochi	From the Bench SmartMedia File Storage, Part 2: Directory Entries Last month, Jeff explained how to exchange embedded data with your PC applications. In Part 2, he'll cover the Smart-Media module and teach you how to navigate within its DOS FAT file structure.
78 Tom Cantrell	Silicon Update Eight Isn't Enough Noting the fact that 67% of respondents in a Circuit Cellar reader's poll had a proclivity for 8-bit chips, Tom's asking you to forget about bits for a moment and examine alternatives from TI, Cyan, and Adelante.
