Questions & Answers10Nan Price | Electronics EntrepreneurAn Interview with Jack GanssleJack Ganssle is a well-known engineer, author, lecturer, and consultant. After learning about oscilloscopes, transistors, and capacitors in his father's engineering lab, Jack went on to write hundreds of articles and several books about embedded development-related topics. He also started and sold three electronics companies, worked on classified government projects, and founded The Ganssle Group, based in Reisterstown, MD. I recently spoke with Jack about some of his career highlights, his current work, and what's next in the embedded design industry. |

Above the Ground Plane54Ed Nisley | Pulsed LED CharacterizationEd continues his exploration of commodity LED characteristics with a stress tester and an optical output detector. After surviving a simulated year of use, the LEDs reveal some interesting data.Download: 278-Nisley.zip |
Green Computing60Ayse K. Coskun | Energy-Efficient Cooling Strategies for ServersAnalyze and Control Leakage and Fan PowerMany servers are overcooled, partially because of the manufacturers' safety margins. It's possible to reduce the cooling energy used by enabling the processor temperatures to rise within safe limits. However, leakage power increases at high temperatures and can cause excessive energy waste. This article discusses how to simultaneously minimize the cooling and leakage energy. |
From the Bench64Jeff Bachiochi | Serial Displays Save ResourcesPart 3: BMP FilesThe first two parts of this series introduced a microcontroller-based project that uses a four-wire interface to a graphic LCD with a touchscreen. It also described how to implement button commands for display customization. Part 3 focuses on the BMP graphical file format. Understanding this file format is essential if you want to work with a graphic icon's data.Download: 278-Bachiochi.zip |
