14 Clayton Gumbrell	QRSS-Rx A Network for Radio Communication The QRSS-Rx features an mbed at the core of a QRSS receiver, which is an RF receiver that can digitize a small bandwidth of RF signals and send them to a server for processing into a spectrum image for real-time display on a website. This project is intended to improve the QRSS grabber system. Download: Gumbrell-259.zip
24 Alexander Pozhitkov	The NakedCPU Part 1: Hardware Experiments and a Roadmap for Navigating Documentation The first part of this two-part series provides an overview of the NakedCPU. This platform is designed to provide full access to hardware and a CPU without any operating system restrictions while working in the protected mode. Download: Pozhitkov-259.zip
30 Steve Lubbers	KartTracker A GPS-Based Vehicle Timing & Monitoring System The KartTracker is a standalone GPS-based vehicle timing system. The LCD on the system's development board operates as the user interface, an integrated accelerometer records G forces, a serial port provides connections to a GPS receiver and a wireless transmitter, and removable flash memory stores data.
Above the Ground Plane 38 Ed Nisley	RFI Bypassing Part 1: Capacitor Self-Resonance With GPS technology and audio radio interfaces on his personal fleet of bikes, Ed's family can communicate with each other while sending GPS location data through an automatic packet reporting system (APRS) network. This article details how to use a KG-UV3D radio interface rigged with SMD capacitors to suppress RF energy. Test-fixture measurements on isolated capacitors are also described.

The Consummate Engineer 44 George Novacek	Build a Robust Power Supply Part 2: Abnormal Surge Voltage In the first part of this two-part article series, you learned how to make a power supply operate properly when the primary power distribution bus voltage is lower than nominal. This article details what happens when it encounters an abnormal surge voltage.
Questions & Answers 48 Nan Price	An Analog Life (And a Lot More) An Interview with Chris Gammell Chris Gammell wears several hats (and safety goggles, when necessary). He currently runs a consulting business, maintains his own website, contributes to and administrates an engineering blog, and co-hosts The Amp Hour podcast with Dave Jones. In December, we discussed his many interests from FPGA-based projects to hardware design to the benefits of writing about what you know.
The Darker Side 52 Robert Lacoste	Playing with High-Speed ADCs Analog-to-digital converters (ADCs) have come a long way since their inception back in 1954. But they aren't always easy to use. Here you learn to use high-speed converters effectively.
Embedded in Thin Slices 60 Bob Japenga	Getting Started with Embedded Linux Part 3: Linux Licensing Issues The purpose of this article series is to get you started with embedded Linux. This month you learn about the various licensing issues an embedded systems designer faces when using Linux.
From the Bench 64 Jeff Bachiochi	Multi-Serial Protocol Tool Armed with a simple serial terminal application on your PC, you can build a multi-serial protocol tool designed to connect from a USB host an I2C, SPI, RS-232/422/485, or Dallas 1-Wire format. You just need to know the format of the data for each device with which you'd like to communicate. Download: Bachiochi-259.zip
