Finding HP: An Italian Engineer’s Journey

Archaeologists are people who study “human history and prehistory through the excavation of sites and the analysis of artifacts and other physical remains.” Over the past few decades, a new type of archaeologist has appeared. They’re devoted to the analysis and preservation of electronic test and measurement equipment in a manner similar to old car aficionados who lovingly restore and modify old automobiles. Among the technology … Read More → "Finding HP: An Italian Engineer’s Journey"

Secure-by-Design, Secure-by-Default: How SpiderOak is Protecting Data at the Edge

This week we are talking all about edge cyber security with David Pearah, CEO of SpiderOak. David and I explore why traditional cyber security solutions do not properly protect edge devices, how SpiderOak is empowering developers to protect their edge applications, and why they are also offering their technology platform as open source software.

TASKBOTs Set to Seamlessly Integrate into Human Workplace Environments

I fear that my poor old cranium has been crammed to capacity with contemporary concepts. For example, I have always understood the abbreviations HIL or HITL to mean “hardware-in-the-loop” in the context of simulation and emulation. Now, however, I have discovered they can also refer to “human-in-the-loop,” which is an experience I’ve not hitherto enjoyed myself.

Max Maxfield publishes an Arduino Uno Bootcamp article series for embedded students and beginners

My friend and EEJournal colleague Max Maxfield writes for several publications. Case in point is a 24-article Arduino Bootcamp series he has written for his Cool Beans column in Practical Electronics magazine, published in the UK. This series of articles is now downloadable as a PDF bundle. The series was two years in the making and sells for the low, low price of £20. If you’re interested, … Read More → "Max Maxfield publishes an Arduino Uno Bootcamp article series for embedded students and beginners"

Findchips: From Engineer’s Hack to Advanced Component Search Engine

As I may have mentioned on occasion, one of my favorite science fiction movies is the 1982 American-Hong Kong dystopian science fiction movie Blade Runner, which was directed by Ridley Scott and is often rated as one of the greatest sci-fi films ever (it was based on the book Do Androids Dream of Electric Sheep by Philip K. Dick).

Steve, Nice read. Soo much technology and little time to write about it all. Keep up the good work. Ray

Hi Steve, when I read "Max’s ability to waffle on defies description (although I’ve just described it)" I laughed out loud. Thanks so much for this review.

Well, that would take a whole new set of grinding wheels, SmithChart. Not that Hillman couldn't afford to do that, and it would sell in Canada. Not sure about the US however.

I'd love to see this technology applied to SKATE sharpening! (Yes, I AM Canadian) :_)
Posted on Mar 31 at 9:46am by Max Maxfield
Sharpening knives is a lot harder than most people think (well, it is if you want them sharpened properly). This is a great robotic application and--as usual these days--one I would have never thought of myself.
