14Kevin Gorga | AC TesterTesting, Troubleshooting, and DebuggingSafety is a top priority when working with electronics and circuits. The AC Tester design is an isolated variable voltage power source that includes an electronic circuit breaker for testing and debugging equipment. An mbed controller displays voltage and current, and it controls the breaker's trip point and response time. In addition, this inventive design can display power factor, VA, and VAR.Download: Gorga-263.zip |

Embedded in Thin Slices44Bob Japenga | Concurrency in Embedded SystemsPart 1: An Introduction to Concurrency and Common PitfallsMost embedded systems have concurrency requirements that designers and programmers must identify, understand, and manage. This article is the first in a series about the topic. Concurrency is defined and pitfalls are examined. |
The Consummate Engineer48George Novacek | Diode ORingDiode ORing is a commonly used method for power backup. But there's a lot more behind the method than meets the eye. This article describes some solutions for maintaining uninterrupted power. |
Above the Ground Plane52Ed Nisley | MOSFET Channel ResistanceTheory and PracticeThis article describes the basics of power MOSFET operation and explores the challenges of using a MOSFET's drain-to-source resistance as a current-sensing resistor. It includes a review of fundamental enhancement-mode MOSFET equations, compares them with Spice simulations, and shows measurements from an actual MOSFET.Download: Nisley-263.zip |
The Darker Side58Robert Lacoste | Radio Frequency MixersFrequency mixers are essential to radio frequency (RF) designs. They are responsible for translating a signal up or down in frequency. This article covers the basics of RF mixers and their real-life applications.Download: Lacoste-263.zip |
From the Bench68Jeff Bachiochi | Build an MCU-Based Automatic Blood Pressure CuffPersonal health products are becoming more and more commonplace. They reinforce regular visits to personal physicians and can be beneficial when diagnosing health issues. This article shows you how to convert a manual blood pressure cuff into an automatic cuff by adding an air pump, a solenoid release valve, and a pressure sensor to a microcontroller circuit. |
