2026-07-08 | By Travis Foss OpenSauce is one of my favorite events of the year. If you've never been, imagine hundreds of creators, engineers, makers, and builders all gathered in one place to show off the projects they've been obsessing over for months. You'll find everything from homemade robots and experimental electronics to wildly creative hardware projects that make you stop and say, "Wait...

2026-07-08 | By Travis Foss If you've ever stood in front of a classroom full of students while an XRP robot starts driving in unexpected circles and you're not entirely sure why — this post is for you. I've been deep in the XRP robot ecosystem for a few years now, which led to an opportunity I didn't see coming: leading a train-the-trainer workshop at Minnesota State University – Mankato in June 2025.

Automotive and industrial system designers are increasingly adopting higher-voltage architectures to improve energy efficiency, reduce system weight, and support higher power levels. Battery management systems, onboard chargers, and other automotive electronic systems now operate at 400 V, with 800 V platforms fast becoming more prevalent in next-generation EVs. Similar trends are playing out in energy storage systems and industrial power-control equipment.

2026-07-01 | By Nathan Jones The lyrics to a popular Broadway song don’t just describe one wife’s entreaties to her husband, but also a powerful debugging tactic! Take a Break - Hamilton (Original Cast 2016 - Live) If you’re stuck on a difficult problem with an elusive solution, don’t forget to take a break. Step away from the desk to take a short walk around your building, to grab a bite of food, to squeeze in some brief exercise, heck, even to just use the restroom or refill your water bottle.

2026-06-29 | By Nathan Jones Replay Attacks Although an unlocked debug port was clearly the largest threat to our system in the last article, a cursory glance at the unlocking process in the source code may have had some of you screaming, “The unlock message is literally [ 0x56 | 0x6 | ‘u’ | ‘n’ | ‘l’ | ‘o’ | ‘c’ | ‘k’ ]?! “Any device can successfully send any unlock message to any car!” Indeed, they can! (Don’t act too incredulous, though; this was almost exactly how key fobs and garage door...

2026-06-01 | By Shruti Garg When I first started working on electronic projects, temperature was the last thing on my mind. I was so focused on getting my circuits to work, making sure the wiring was right, the code ran, and the sensors were giving me the right values. But over time, I started noticing something: my circuits would work perfectly at times, but other times they wouldn’t. Even though the code was the same and the wires were set up the same way, I would still get different results.

This volume opens with a feature from Allegro Microsystems examining the APS11203 and APS12203 Hall Effect switch and latch sensors, highlighting their role in delivering robust, accurate magnetic sensing for demanding industrial and automotive environments. STMicroelectronics follows with a deep dive into the VL53L8CX, showcasing how advanced time-of-flight technology enables high-performance distance and presence detection in compact, power-efficient systems.

A significant aspect of engineering centers on the art of making component tradeoffs with respect to your determination of system “must haves” and “nice to haves.” These tradeoffs include speed versus power dissipation, footprint versus functionality, and capabilities versus cost. Making these decisions involves “what if” modeling and simulations along with an experience-earned sense of what will work and to what extent.

In a rapidly evolving and highly competitive environment, Internet of Things (IoT) developers must answer some important questions: How much data will my device need to send and receive? How long should the battery last? How far from a gateway can it reside? How many devices can I get on a single network? How easy is it to set up and secure?
