Above the Ground Plane 22 Ed Nisley	Building Boxes Ever wonder how Ed packages the gadgets he shares with us? This month he gives box building its due. From reusing large boxes to building small ones, it's all inside this column.
From the Bench 26 Jeff Bachiochi	HTML Light-to-Frequency Conversion Part 1: TSL230R-Based Pulse Oximeter TAOS light-to-frequency converters are becoming increasingly popular amongst designers whose applications require light-sensing capabilities. One reason why is because designers want digital output rather than analog. In this column, Jeff explains why a TAOS TSL230R is the perfect part for the pulse oximeters used in hospitals.

36 Scott McOlash	Visualizing History Record and View High-Level Software Behavior Software can be challenging to understand, especially when it doesn't behave as expected. Traditional debugging tools and techniques provide insight into what your code is doing, but only at a low level. Fortunately, Scott can teach you a better way to visualize the high-level behavior of software systems. Download: McOlash173.zip
Applied PCs 44 Fred Eady	RabbitWeb HTTP Server Neither power outages nor hurricanes can keep Fred from helping you create web page interfaces that control Rabbit-based embedded systems. Read on to learn how he recently built a RabbitWeb HTTP server under some of the worst conditions imaginable.
54 Bob Armstrong	Artificial Life Display Part 1: Design Basics Bob's artificial life display simulates a cellular automaton designed by John Horton Conway in 1970. Is this more art than engineering? The answer is in the eye of the beholder. In the first part of this series, Bob shows you how his innovative design works. Download: Armstrong173.zip
62 Philip Nowe	An FPGA Experimenter's Board Philip sees an FPGA in your future. Why? They're inexpensive, and you can tailor them to meet your design goals. Read on to learn how easy it is to build a Spartan-3-based FPGA experimenter's board. Download: Nowe173.zip
72 Tom Napier	Reference Generation Build a 60-Hz Generator with an NCO Is it possible to generate a pure 60-Hz sine wave with an NCO? After crunching some numbers and looking through past issues of Circuit Cellar , Tom did just that. Read on to learn how he used a PIC-based firmware NCO to build a 60-Hz generator. Download: Napier173.zip
Silicon Update 78 Tom Cantrell	Position Statement Tom says Xemics's SlimGPS represents a technological breakthrough that will bring GPS capability to a slew of products like cell phones, PDAs, and economy cars. Not only is the tiny, low-power, three-chip module easy to work with, it's surprisingly affordable.
