A Simple Circuit for an Inexpensive Robot

With a versatile and practical design such as the Stiquito, it's hard to keep it from evolving into more advanced forms. This time, James and Mark have taken the Stiquito and applied concepts that provide a higer survival rating for robots.

PDF USB Chip Choices

Finding a Peripheral Controller

Today, most peripheral devices are designed with USB connections. Designing USB peripherals can get tricky, but choosing the right chip can make a world of difference. Jan knows her USB, so you might want to choose to listen up.


Brian Millier

Back to BasicX

Part 2: NetSnoop Application

Now that we've met NetMedia's BasicX development system, it's time to put it to use. You can unplug the soldering iron for this one because Brian is taking us through the software for a background debug monitor that he developed.

Drive a Portable Inverter with a PIC16C54

If you have a small appliance that needs a portable power source, then you'll want to pay attention to what Tom has to say. When it came time to upgrade an earlier project, usign a PIC to drive the portable inverter was the obvious choice.

Real-Time Executive for Multiprocessor Systems, Part 3: Running i386 RTEMS Applications

RTEMS has some great networking support features; this month Ingo covers those in more detail and shows us just what it takes to get an i386 RTEMS application up and running. And, it's easier than you think!

Calling for Backup, The Value and Methods of Backing Up

Backing up things is a lot like long-term investing -- you may not see immediate benefits, but someday you'll be glad you did it. This month, Fred takes a look at PowerQuest's simple and practical backup imaging software.

Implementing a PIC-SERVO Controller

Before you get your motor running and head out on the highway, you may want to listen to what Alan has to say about the PIC-SERVO from JR Kerr Engineering. If you need to control a DC motor with encoder feedback, this chip will fit the bill nicely.

Two Ports in a PIC

A Communication Thermostat

Getting your thermostat to communicate with your HCS-II may be easier than you think, according to Mike. He used a PIC16F876 to create the Stat-Link and now there's no lack of communication between his thermostat and his HCS-II.

Op-Amp Specifications, Part 4: AC Applications

Well, all good things must come to an end, so this month Joe wraps up this series on op-amp specifications. Of course, there's still a lot to be covered, but understanding the needs of AC applications will get you started.

DFPs: Riding the Wave of the Future

Jeff set out to build a reusable peripheral I2C device that he could recycle in future projects. The practicality of LED character displays made the application choice easy.

Silicon Update

Swiss Army Chip, Programmable System Devices

When it comes to combo chips that have what it takes to make it, Tom thinks the success or failure of such chips may have a lot more to do with what else is going on in the world of silicon.

Gerard Fonte

PDF HTML Looking at the Specs

With this article, Gerard helps us answer some of the questions about one of the defining characteristics of most engineering projects, showing us that, when engineers, marketeers, and customers all have a common goal, they can get the most out of specifications. But, is it really possible for all three to come to an agreement? See what Gerard has to say.

Michael Chan

PDF HTML Build a Virtual Wireless Automation System

What is "real" and what is virtual reality? It's hard to tell nowadays. Similarly, Michael's project scheme is wireless, but is it really? It seems like it because there is little or no wiring or installation involved when you want to make a change to your system. Let Michael take you through the steps, then maybe you can get virtually wireless.

PDF HTML Decisions, Decisions ...

Are you creative? Well, if you are the engineer who has to make the decision concerning a certain design, then you had better be. George discusses some of the more important aspects of decision making and shows us that, by understanding the problems and options available, we can decrease the risk and choose the right alternative.

Number Crunching with Embedded Processors

This month, George walks us through binary numbers, embedded processors, and how different numbering systems work together with CPU instructions and the C language. He takes us through the steps and then encourages us to walk on our own with different examples. And remember, practice makes perfect!
