Embedded system security methods

Embedded System Security for Hardware Designers Today, I had the pleasure of an open discussion about hardware hacking with the security experts at VDA Labs in Grand Rapids, Michigan. James King, Ethical Hacker, and Josh Sharpe, Cybersecurity Consultant, walked me through what they look for when trying to compromise an embedded system. I thought I would see what hardware designers can do to slow them down and pass on that information to my fellow designers. VDA Labs helps companies determine Read Article

Ceramic Capacitors - Why Voltage and Capacitance Ratings Aren't the Full Picture

Ceramic Capacitors - Why Voltage and Capacitance Ratings Aren't the Full Picture Ceramic Capacitors - Why Voltage and Capacitance Ratings Aren't the Full Picture The true capacitance of ceramic capacitors rarely matches what is stated on the specifications once they’re installed in end applications. Depending on what frequency, voltage, and dielectric you’re using, true capacitance can be vastly different from what you’d expect. This guide walks through the common misconceptions and demonstrates how to select the right Read Article
