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 […]
RISC-V: an Open Instruction Set Architecture
The benefits of open source have been bestowed upon an Instruction Set Architecture (ISA) called RISC-V. One of the earliest, best-known examples of open source technology is Linux. For a widely accepted, official definition of open source, see The Open Source Initiative. Open source does not stop at Linux, however. One of the more recent […]
MOSFETs: What is RDS(on)?
RDS(on) stands for “drain-source on resistance,” or the total resistance between the drain and source in a Metal Oxide Field Effect Transistor, or MOSFET when the MOSFET is “on.” RDS(on) is the basis for a maximum current rating of the MOSFET and is also associated with current loss. All things being equal, lower the RDS(on), […]

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 […]
