14David Penrose | A Different TimeshareBuild a Timeserver SystemYou can build a timeserver that listens to a GPS signal, extracts the time and date, and retransmits this information to remote systems. The design manages more than one microcontroller that has a real-time clock with an I2C interface and keeps all the clocks synchronized.Download: Penrose-258.zip |
24Andrew Levido | mbosA Real-Time Operating System for mbedThis project enhances the NXP Semiconductors mbed environment with a real-time operating system (RTOS). Designed specifically for mbed, "mbos" is a true preemptive multitasking RTOS that's scalable to support virtually any project developed on the NXP Semiconductors LPC1768 platform.Download: Levido-258.zip |
36Steve Johnson | The SMD Air BathA DIY PCB Preheating SetupThe SMD Air Bath is a temperature controller that can preheat a surface-mount device printed circuit board assembly before reflow with a hot air pencil. The preheating capability activates the flux, reduces the chance of thermo shock, relieves the heat load from the hot air pencil, and reduces thermo-mechanical stresses.Download: Johnson-258.zip |
Questions & Answers46Nan Price | Innovative Research & DesignAn Interview with Mike SmithMike Smith is a professor of Computer Engineering at the Schulich School of Engineering, University of Calgary, Canada. His main interests are in developing new biomedical engineering algorithms and moving them onto multicore and multiple-processor embedded systems in a systematic and reliable fashion. Mike recently became a convert to the application of Agile Methodologies in the embedded environment. Mention "test-driven development" and his eyes light up. In 2011, Mike had his Analog Devices University Ambassadorship renewed for the eleventh straight year. In December, Mike and I discussed his interests and some of his students' projects. |
Lessons from the Trenches50George Martin | ADCs and Signal FilteringYou understand the process of creating a new product from start to finish. Now it's time to dig into the specifics, starting with analog-to-digital converters and their supporting hardware and software. Many of the techniques in this article can be applied to other design dilemmas. |
The Consummate Engineer56George Novacek | Build a Robust Power SupplyPart 1: Power DissipationBuilding a robust power supply design seems like an easy task. The first part of this series on power supply design focuses on switching regulator modules, power dissipation, and low-voltage operation. |
Embedded Unveiled60Richard Wotiz | Digital X-Ray SensorsEver wonder how X-rays work? Here's a detailed look at imaging techniques, from their early inception to today's advances. You'll also learn how a CMOS imaging sensor functions. |
From the Bench68Jeff Bachiochi | Quantifying PrecipitationConstruct a Device to Measure Rainfall VolumeThis tip-bucket mechanism uses a Hall-effect sensor and a microcontroller with debugging capability, LEDs, and configuration jumpers to measure rainfall volume. The sensor's open-collector output is connected to the microcontroller's interrupt input.Download: Bachiochi-258.zip |
