This week Parker and Stephen welcome Joe Grand to the show to discuss insecure IoT devices. Inspired by a recent incident where Bosch wrenches were infected by ransomware called DRILLCRYPT, the guys asked Joe to join them to talk about how attackers could compromise the safety of the wrench and cause safety issues for users. Of course, this kind of breach could impact almost any company and its products, and so many topics were covered, including:
“Actually, it’s Dr. Grand…”If you’re in attack mode, firmware updates are greatSupply chain issues are hard enough to manage without these security breachesA lack of security can be a business decisionGive me convenience or give me threatsThe hardware industry isn’t as well-versed as the software industry isHow to update 10,000 devices in the fieldHacking is problem-solving (someone tell the FBI)“If you’re not being sued, you’re not working hard enough’Sourcing parts and the risk of getting counterfeit partsWhy a firmware update shouldn’t disable your carResisting Big ToiletSubscription models for…everything…The importance of Design For Security measuresIs getting hacked more of a marketing problem than an engineering issue?Engineering ethics and hacking and designAbout our guest:
Joe Grand, also known as Kingpin, is a computer engineer, hardware hacker, teacher, advisor, daddy, honorary doctor, and occasional video maker. He has been creating, exploring, and manipulating electronic systems since the 1980s. This is his third appearance on our show and first since 2019!

This week Parker and Stephen welcome Kent Johnson to the show to discuss ethics in engineering. It’s a topic that has been alluded to over the course of Circuit Break, but this is the first time Parker and Stephen have delved into it with a real expert on the matter. Yes, most companies have standards and regulations and a moral code that guide them but, as Kent suggests, there are more ethical gray areas in the realm of engineering than we might realize. Topics covered here include:
Discovering something isn’t being done properly at your new jobAgreeing to work on something with life-or-death consequences, and you don’t really know what you’re doingBypassing important project safety tests to meet a deadlineCrediting others in an age of ChatGPT and redefinitions of plagiarismHow do you credit and use open source code?Why siloed departments at companies are causing such harm to work dynamicsThe tyranny of the specThe true dangers of “failure” or “gotcha” work culturesAccepting accountability and being willing to changeAvoiding QC by zipping the lip+moreAbout our guest:
Kent Johnson is Senior Corporate Advisor for the Religious Freedom & Business Foundation and a management consultant on religious diversity at work. With over 37 years of experience as a Senior Counsel at Texas Instruments, Kent is a seasoned legal expert who specializes in corporate law, ethics, product liability, antitrust, medical/FDA law, and mergers and acquisitions.

A recent Circuit Break Community thread about K-map design inspired a tangential conversation about how well certain subjects are taught in college. Parker and Stephen love a good tangent, thank you, and so they dug in by recalling their own experiences at school with excellent professors who clearly wanted electrical engineers to succeed, while other instructors and their teaching methods were challenging or else just downright bizarre. Other topics covered here include:
How a terrible electronics professor can impact someone’s careerIs a “self-paced” classroom really just lazy teaching?Still not knowing how Bode plots workA strange digital circuits analogy where chickens and snakes are shockedWatching videos like you’re in A Clockwork OrangeA grade curve so severe, a 17% was a BClasses and profs we lovedWas a class hard, or was the professor just absolute garbage?Still having nightmares about forgetting to go to class for a whole semesterHeat Shrink Voltage Ratings+moreRelevant links:

This week Parker and Stephen welcome James Lewis back to the show after a rather long absence! The occasion stems from James chiming in on a Circuit Break Community thread that Stephen started, asking all about component aging effects. Stephen posed questions like, “What happens to resistors over 5 years? How about 20 years? Are there rules of thumb or better yet, calculations for aging?” And helpful engineer that he is, James got in there and tried to provide some answers before agreeing to appear on the show to elaborate. Other topics covered here include:
How no one is completely sure about how to approach component agingWhen component aging actually affects designersThe difference between aging and reliabilityThe impact of components lasting longer than they were meant toVariables, parameters, and other factors that can inhibit and exacerbate agingLevels of violence in polymer tantalum explosionsThe history of constantsDevice longevity lawsHow to define rated voltage for a capacitor+more!About our guest:
James Lewis aka Bald Engineer, is a freelance electronics content creator. You might recognize James from the YouTube channels AddOhms and Workbench Wednesdays from Element 14. His interests include talking too much about capacitors, repairing vintage computers, and making unique PCBs that go into poorly designed 3D-print enclosures. James has been on the show a few times now, including episode #141 and #222 to discuss testing and validating PCB assembly design. The episode about ceramic capacitors is still one of Parker’s all-time favorite episodes!Relevant links:

Parker and Stephen discuss a recent news story about how car manufacturers are increasing their focus on Software-Defined Vehicles (SDVs) which are cars that use more software instead of physical components to control vehicle functions. This prompted a comparison between SDVs and Drive-by-Wire or DbW technology in the automotive industry, which is the use of electronic or electro-mechanical systems in place of mechanical linkages that control driving functions, how DbW relates to Fly-by-Wire tech and the fate of the F-117 Nighthawk, how Marvell Semiconductor is working on technology, particularly Ethernet, to support this change to SDWs, plus we get a brewery project update from Stephen, and much more!
