Read Part 1 here. In 2006, the creators of the TV series Jericho imagined how nuclear detonation would affect a small Kansas town. Large solar-based EMPs have been documented. In 1859, a solar storm dubbed the Carrington Event hit the Earth’s magnetosphere. One of the largest solar storms on record, the CME in 1859 caused […]
What happens to an MCU if there’s an EMP or Solar Superstorm? Part 1
An Electromagnetic Pulse (EMP) is an impulse or blast wave that’s generated by geomagnetic activity due to solar flares, solar storms, solar superstorms, or the detonation of nuclear weapons. The horrible truth is that an EMP can wipe out electronics by inducing inductive coupling on traces, wires, or any conductive media within hundreds to thousands […]
Mistakes to avoid when submitting a design for PCB assembly
Simple prototype Printed Circuit Boards (PCBs) require, on average, 11.6 physical prototypes, whereas more complex PCBs require as many as 16.[i] And according to Advanced Assembly, a prototype PCB assembly house, “94% of assembly data is accidentally submitted with errors.”[ii] PCB assembly houses will extract design data from PCB design files and create a PDF […]
Understanding wireless across the spectrum
Waves are part of our world as both waves in the ocean and radio waves coming in from the Sun’s corona share fundamental properties.[i] Wireless communication was born from the science of waves and how they travel. After more than a hundred years of study, we’ve organized waves into a large electromagnetic spectrum (EM) that […]
Considerations for battery-powered designs
How can you make your resume really stand out? This has been the topic of books, articles, class assignments, and blogs for decades. It came up in conversation one day, and a friend of mine had a unique story. I’ve included it below, with some edits. “With so much written on the topic, there is […]
When asked the impossible, ask questions before proceeding
Sometimes a client will ask for the impossible and expect it at low cost. Or worse yet, the sales engineer in your company will win a project on a low bid because he/she thought it could be accomplished in a “creative” (but impossible) way. What if you were tasked with a wirelessly communicating embedded project […]
The best (and nearly) free education that you can get…earning $67K to $103K a year in under 3 months
If this sounds too good to be true, it is not: read on. Abe Lincoln was one of those guys that didn’t have a college education but made it to the top as a self-educated man. Back then, you didn’t have to have a 4-year college degree to get a decent paying job. Nearly everyone […]
