	HIGH-TEMPERATURE ELECTRONIC DESIGN
		Part 1: What Are Your Options? by George Novacek Design options for temperatures beyond 125ýC have been scarce in the past, but this month George shows us that there are ways to get around the technical problems and risk and still create state-of-the-art designs. Electronics from the common to the complex can benefit from finding new alternatives geared for elevated temperatures. If youýre successful, the result could be simpler designs that are more robust, economical, and reliable. January 2001
	MONITORING THE REVOLUTIONS
		A Pedal Cadence Counter by Matt Meerian Staying physically fit is a way of life for most today. To get an optimum workout, Matt creates a design that combines two of his favorite hobbies, electronics and mountain biking, to reach the ultimate workout goal. By combining low-level programming with high-level language, you can tailor the cadence barometer for whatever activity suits your interest. Any way you cut it, you can gauge for accuracy while doing the exercises you enjoy. January 2001
	AN S7600A/PIC16F877 JOURNEY
		Part 1: Laying Out the Tools by Fred Eady Depending on the tools of the trade as well as the skill of the craftsman, Fred embarks on an Internet engine journey this month. As he takes you through this series, youýll see the end result of a functional Internet communications device that speaks many languages and interfaces. Laying out the tools seems a good place to start. Skill is sure to follow. January 2001
	DESIGNING WITH VHDL
		by Ingo Cyliax Once something becomes mainstream, you better think about jumping on board. Such is the case with hardware description languages (VHDL) for designing FPGAs and CPLDs. Even if itýs new to you, Ingo explains that Xilinxýs WebPack makes digital design understandable. The benefits far outweigh the chore of having to learn the language. And, because itýs at no cost to you, what more could you ask for? January 2001
	BEHIND THE SCENES
		A Comprehensive Look at ColdFire by George Martin George puts on a stage show of sorts with this installment, as he explores the PC/Internet combination and, in particular, Motorolaýs ColdFire processor. Taking its place as a standard CPU model, the ColdFire design is outlined on Motorolaýs web site, where all manner of datasheet and manual information is made available. If youýre still not convinced that the needed support is there, the addition of an extensive discussion group should seal the sale for you. January 2001
	BEING MERRY WITH USB
		by Tom Cantrell Tom tries to stay positive as he reminds us of the familiar grief of the three-finger salute (Ctrl + Alt + Delete) and the agony of rebooting. Negativity aside, he looks for solutions to his problem of two printers on a single parallel port in everything from calling tech support to calling an exorcist. A USB interface helped to remedy the situation. January 2001
