Practical Linux Forensics by Bruce Nikkel, a professor of applied sciences at Bern University in Switzerland, (No Starch Press) covers how to search a Linux-based system for digital evidence that will allow you to draw conclusions and create forensic reports about a particular case or incident. The book is thorough, spanning 398 pages. It covers […]

Reconfigurable intelligent surfaces: Video interview with standards group chair
Dr. Arman Shojaeifard of Interdigital Europe explains the concept behind reconfigurable intelligent surfaces and how the standards group he leads will develop those standards.
The brushed DC motor: Still a very viable option, Part 2: Applications
Brushless DC and stepper motors may get more attention than the classic brushed DC motor, but the latter may still be a better choice in some applications. The brushed motor is available in sizes from tiny ones providing a few inch-ounces of torque through hundreds of horsepower and has been used successfully for over 100 […]
The brushed DC motor: Still a very viable option, Part 3: Drivers
Brushless DC and stepper motors may get more attention than the classic brushed DC motor, but the latter may still be a better choice in some applications. The attractiveness of brushed DC motors for some applications and the challenges of optimizing their performance has attracted vendors of special driver ICs which are well-suited for this […]
MCUs for ADAS – what’s the difference?
The emergence of advanced driver assistance systems (ADAS) is changing how designers use and specify microcontrollers (MCUs), but it’s only one dimension of the changes occurring in the design of automotive systems (Figure 1). This FAQ will begin with the basics of AEC-Q100 requirements for automotive integrated circuits – those requirements are not going away […]
Pouch-type EDLCs for thin-and-light circuit designs
Supercapacitors now come in a small, thin format that makes them candidates for uses characterized by cramped quarters. Shinji Higuma, TDK Corp. In the next several years, the internet of things (IoT) will include tens of billions of connected devices. Consumer, industrial, medical, and automotive applications will feature connected devices, but not all connected devices […]
The brushed DC motor: Still a very viable option, Part 1: Operation
Brushless DC and stepper motors may get more attention than the classic brushed DC motor, but the latter may still be a better choice in some applications. Most designers looking to choose a small DC motor – a sub- or fractional-horsepower unit, typically – usually look initially at just two options: the brushless DC (BLDC) […]
Managing smart street lighting design
Wi-SUN may well be the linchpin that turns street lighting into a scalable IoT umbrella offering a multitude of solutions beyond illumination. Soumya Shyamasundar, Silicon Labs According to the World Bank, legacy street lighting systems based on traditional technologies can account for as much as 65% of a city’s electricity consumption. The energy consumption, of […]
Tolerance analysis distinguishes prototypes from production units
It’s not enough to model and simulate circuit behavior – you also have to investigate the effects of component variations from their nominal values due to unavoidable tolerances. There’s a semi-serious quip that scientists can build one of anything – but just one; it takes engineers and production experts to build it again and again […]
Odd ball application department: Using a scope to display SEM images
The Applied Science YouTube channel run by Ben Krasnow (who in his day job is a hardware engineer at Verily, Google Life Sciences) focuses on interesting applications of science and technology. One video in particular caught our eye where Kranow uses an oscilloscope to help view digital images captured by a scanning electron microscope made […]
