I-Connect007 Editor’s Choice: Five Must-Reads for the Week

August 7, 2026 | Nolan Johnson, I-Connect007

Are you familiar with the “locus of control," which describes how much we believe our actions can change the outcome of our lives? Internal locus of control, for example, is the belief that our actions greatly shape our outcomes; external locus of control holds that external forces have a greater influence than our actions on how our lives play out. How we view our own locus of control can strongly influence how we respond to the world, perhaps even creating a self-fulfilling prophecy situation. The news has taken a more languid pace this week. Not so, however, for our intrepid band of I-Connect007 columnists, who thoughtfully tackle some chunky locus of control topics.

A display is one of the few electronic subsystems where PCB design decisions become visible to the end user. A few milliohms of resistance, a slight impedance discontinuity, or a few degrees of temperature difference may never matter elsewhere in the product. In an LED display, however, those same design decisions can become a visible defect. Behold the power of the human eye. Over the years, I've reviewed hundreds of PCB layouts spanning everything from industrial controls and aerospace electronics to medical devices and high-speed computing systems. Every design presents its own unique challenges, but display electronics have always stood apart.
