George Novacek

Are You Grounded?

In previous issues, George helped us develop sound EMC, ESD, and transient control designs. This month, he wants to make sure our designs are grounded. In this article, he talks about several pragmatic and nontheoretical grounding and bonding methods.


Tom Napier

Embedded Smarts Fix Analog Flaws

Broad-minded engineers tend to think outside the box when they're trying to fix flaws in their designs. Tom draws on his understanding of analog and digital design, numerical processing, and embedded firmware to cope with the nonlinearity of analog components.


Aubrey Kagan

HTML Driving the NKK Smartswitch

Part 2: Graphics and Text

Whether your message is one of workplace safety or world peace, the long nights of brooding over ways to tell the world are over. Now that you're comfortable with the interface to drive the Smartswitch, Aubrey will show you how to display your ideas as text and graphics.

Above the Ground Plane

PC Audio Bits

What's so hard about building a trouble-free audio system? All you need is a stock PC, good software, and decent digital data and high-resolution converters, right? Not necessarily. Ed shows you what the datasheets cannot as he notes what happens when bits meet hardware.


Frantisek Bachleda

Digital Ignition System

Building Without a Distributor

Tinkering with cars can be an expensive hobby. But upgrades don't always have to cost a fortune. In this article, Frantisek shows you a cost-effective way to build a digital distributorless ignition system that will boost your car's overall performance and power.



Jeff Bachiochi

RISCy Business

Part 1: RISC Projects by Cornell Students

Jeff is heading back to college. In this article, he walks you through several projects that Cornell University students entered in the Atmel Design 2001 contest. So, grab a pen and pad and get ready for a lecture on the RISCy business of digital system design.


Neil Cherry

HTML The Open-Source HCS Project

It's been a while, so now it's time to set the record straight. Despite the rumors, the HCS II project is not dead. In fact, HCS has been licensed and is now an open-source project. In this article, Neil brings us up to speed on the HCS II projectís past, present, and exciting future.


Chris Cantrell

The OO CarolBot

Don't learn from your mistakes; avoid making them instead. Chris is an advocate of foresight rather than hindsight. In this article, he will show you how to use object-oriented programming techniques to build modules that can be reused in future robot designs.



Noel Rios

The AT89C51/52 Flash Memory Programmers

When faced with a plethora of applications to design, it's essential to have a versatile microcontroller in hand. Noel knows just what you're looking for: the AT89C51/52 micro-controllers. To get you started, he'll describe his inexpensive microcontroller programmer.

From the Bench

SmartMedia File Storage, Part 3: Reading a File

Jeff has explained the basic circuitry and how to navigate within the DOS FAT file structure. Now, he'll demonstrate how to read SmartMedia files and implement ECC routines to verify the integrity of your data.


Tom Cantrell

Silicon Update

FPGA News Flash

After two decades at the top of the FPGA world, Xilinx and Altera may soon find customer loyalty shifting in another direction. Tom explains that Actel is on the verge of sparking a flash memory revolution.
