34Scott Weber | Controlling Access with a Proximity CardOpen the Door to Manchester EncodingA radio frequency proximity card and reader can be used to control access to many things. This article explains how the data is Manchester encoded on the card, how to find the bitstream's beginning, and how you can use the data and clock lines to bit bang the waveforms into a microcontroller.Download: 269-Weber.zip |
Questions & Answers42Nan Price | Engineering Innovation, Experimentation, & ExplanationAn Interview with Stuart BallBeginning with his early fascination with electronics, Stuart Ball has always nurtured his curiosity, figured out how things work, and designed useful projects. We recently discussed some of his early microprocessor designs, his interest with Atmel's AVR C coding, and his dream project, which involves enabling future engineers to learn through experimentation. |
Above the Ground Plane44Ed Nisley | Arduino Survival GuidePower SupplyArduino boards appear in many projects that call for a microcontroller, because they're easy to use and program. In this column, Ed explores the often-overlooked Arduino power supply, shows why Arduino projects sometimes exhibit difficult-to-debug problems, and describes how to keep your Arduino project running smoothly. |
The Darker Side50Robert Lacoste | Locked InSynchronous Detection ExplainedAt some point in your electronics engineering career, you'll need to extract a signal in a noisy environment. When the time comes, consider a lock-in amplifier. You'll find the information in this article about lock-in amps and synchronous detection invaluable when you need to measure a small and noisy signal's amplitude or phase. |
Embedded in Thin Slices58Bob Japenga | Concurrency in Embedded SystemsPart 4: Introducing Linux and ConcurrencyThis is the fourth article in a multi-part series about concurrency in embedded systems. Here you learn how embedded Linux provides the mechanisms to design robust systems with concurrency. |
The Consummate Engineer64George Novacek | Product ReliabilityPart 2: The Meaning of Failure RateNow that you know various calculations for determining a product's failure rate, it's time to investigate how the numbers figure into your design. A successful product designer must understand the concept of reliability and know how to make smart decisions about components based on failure rate data. |
From the Bench68Jeff Bachiochi | Energy ExtractionPowering Up with Heat TransferIf you can generate the right amount of heat, you can produce electricity for a variety of purposes. Here you learn how to use fire, a Peltier device, and little ingenuity to power up small devices.Download: 269-Bachiochi.zip |
