20Stuart Ball | Build a Digital Dip MeterA dip meter is a handy piece of test equipment typically used to check a device's resonant frequency or as a signal source to tune receivers. This article describes how to use a microcontroller to digitize a dip meter's display and explores how to maintain functionality when converting a design from analog to digital.Download: 271-Ball.zip |
26William Myers Guo Jie Chin | 3-D PaintA Complete Hardware and Software Package3-D Paint is a complete hardware and software package that uses free space as a canvas and enables you to draw in 3-D by measuring ultrasonic delays. A standard PC running MATLAB captures your movements and returns them in real time.Download: 271-Myers-Chin.zip |
32Richard Lord | Digital Camera ControllerPart 3: Build a Generic Front-Panel BoardThe first parts of this article series introduced the microcontroller-based Photo-Pal and described its hardware and construction as well as its code, user interface, and timing. Many elements of the Photo-Pal's design can be used to create a generic front-panel board for use with numerous other applications. |
Embedded in Thin Slices37Bob Japenga | Concurrency in Embedded SystemsPart 5: Designing Robust Systems with LinuxThis is the fifth in a multi-part article series examining concurrency in embedded systems. This article discusses some other ways embedded Linux helps you design robust systems with concurrency. |
Questions & Answers41Nan Price | Engineering and "Pure" ResearchAn Interview with Colin O'FlynnColin O'Flynn is an electrical engineer and graduate student at Dalhousie University who is studying cryptographic systems. He has experience with software programming, RF layout, and PCB and FPGA design. Here Colin provides some background information about his introduction to designing with electronics, his involvement with 802.15.4 wireless communications, and his current projects, including a programmable logic board. |
The Consummate Engineer46George Novacek | Fault-Tree AnalysisFault-tree analysis tracks a system event -- most often a failure -- down to its root cause. It also supports the system's safety and reliability assessment by determining the event's probability of occurrence. |
Above the Ground Plane49Ed Nisley | Arduino Survival GuideDigital I/OThe digital I/O bits on an Arduino connect it to the real world, but those microcontroller pins have analog properties that many designers neglect. Ed explores how the components inside the microcontroller affect the circuit's operation and shows how to avoid some common problems. |
The Darker Side54Robert Lacoste | Introduction to Standing WavesStanding waves are oscillations that remain in a constant position. This article describes a signal generator-based experimental design you can use to see and measure standing waves. It also shows how signal reflectors are used to generate standing waves on a transmission line.Download: 271-Lacoste.zip |
From the Archives60Roy Franz | The WiFi SniFiSniffing In and Out of Wireless NetworksAre you having trouble locating 802.11b wireless networks? Don't worry. Roy has the perfect solution. The WiFi SniFi is a compact, easy-to-build device that can "sniff" out wireless networks and display the appropriate packet information. |
From the Bench68Jeff Bachiochi | QR Coding for EngineersQuick response (QR) codes are 2-D matrix barcodes with fast readability and large storage capacities. This article examines QR formats and describes how to implement a Windows PC program that formats your data into QR code symbols. Options such as error correction, masking, and other modifications are also discussed.Download: 271-Bachiochi.zip |
