Aaron Dahlen

The Engineer's Alarm Clock

Design a PIC-Based Lamp Controller

Aaron always wakes up to a rising sun, regardless of the weather outside. How's that possible? He designed a PIC18F252-based alarm system that gradually brightens a 120-VAC bulb over a half-hour period.

An SPWM Calculator

Using the Switched Integration Technique

Sine pulse-width modulation (SPWM) is a technique frequently used in variable frequency drives for speed control in AC motors. Armando and Sergio present the QUSPWM algorithm as a simpler variation of SPWM based on a switched integration operation.

HTML Uncomplicated Wireless Networking

Wireless networking is easy, as long as you have the right tools for the job. This month, Fred shows you how to "get on the air" with Z-World's Wi-Fi application kit, which includes a Linksys Wi-Fi card and RCM3100 module. Go wireless in no time.


Brian Millier

HTML Multilab

Build a Z8 Encore!-Based Multipurpose Test Instrument

Brian's Multilab is comprised of an arbitrary function generator, a digital pulse generator, and more. Read on to learn how he built this multipurpose test instrument.

DMX-512 Control

Build a USB-to-DMX-512 Converter

Stefan recently found himself in need of a controller for a lighting system. In this article, he describes how he used an FTDI FT232BM USB-to-serial converter chip to achieve DMX-512 control.

Tom Cantrell

A Simple Plan

Is the MAXQ a RISC, CISC, or something in-between? According to Tom, it doesn't matter. What is important is that the MAXQ is becoming increasingly competitive in the MCU market.
