Chuck Lewin

Motor Commutation Techniques

It's a never-ending race to get the most performance from your system. But, according to Chuck, motor commutation is a good springboard for flying over the hurdles of oscillations, overshoot, and all those other motor-stability problems.


Chris Sontag

PDF HTML, HTML Web-Implemented Irrigation System

Tired of relying on the weatherman in this El Nino year? Chris is, too. After seeing all those automatic sprinklers working in the rain, he decided to hook up a controller to the 'Net for live updates, making this device truly intelligent.


Beau Wadsworth

PDF, PDF HTML, HTML Smart Building-Control Applications

Dreaming of those smart buildings of the future? Well, it's time to wake up. Beau's powerful machine-learning software figures out building occupancy patterns, yet it's simple and small enough to run on any microcontroller.

All BIOSs are Not Created Equal

No PC-based CPU is suitable for embedded applications without an equally tough BIOS. Scott helps us make sure our embedded-PC products are fit enough to meet the exacting demands of medical, military, and factory environments.

Embedded RT-Linux, Part 1: General Introduction

Ingo kicks off this miniseries on using Linux as an embedded operating system with an overview and a comparison to other freely available OSs. As we start seeing more and more projects that use Linux, it'll be pretty clear why they do.

Note: Additional discussion of licensing issues by Dave New in INK 102 Reader I/O. There are also some updated URLs for RT-Linux.

Fred Eady


emWare Top to Bottom, Part 1: Monitoring via the Internet

There may have been some good old days, but Fred's not necessarily one to live in the past. He's reaching into the future, and it's looking like the future relies heavily on control via the web. Join him for a look at emWare's offering.


David Tweed

PDF HTML MicroSeries

Digital Processing in an Analog World, Part 2: Technology Choices

This month, David discusses the pros and cons of several converter technologies in terms of performance, cost, and complexity. He covers everything from basic flash ADCs to PWM, so we know where to turn for our applications' needs.


Jeff Bachiochi

From the Bench

MIDI, Part 2: The Show Must Go On

The show must go on, and so does Jeff as he finishes his MIDI animator project. After discussing MIDI control, Jeff completes the performance by showing how lighting engineers can get in on the act.

PDF HTML, HTML Silicon Update

Socket Rocket

The SX MCU from Scenix is fast, runs on almost anything, gets good mileage, and you can park it anywhere. And, Parallax's SX-Key makes for some easy riding. Will we be seeing biker bars in Silicon Valley?
