Aggressive with Passives

Most of us think about capacitors the way a chef thinks about salt – knowing that it’s never the star of the show, having a keen awareness that you need just the right amount, being vaguely conscious of the fact that there are multiple, subtly different types… When we’re debugging our board, there are often times when something mysteriously isn’t working right. When all … Read More → "Aggressive with Passives"

Battery Roundup

Batteries have historically been perceived as something of a staid technology – at least in a lot of minds. I remember back when we were diving into 3-V standards at JEDEC many years ago, and we invited battery folks to help advise us. I came away with the distinct sense that battery chemistry was pretty much what it was and would always be. Yeah, I saw you stifling that yawn…Read More → "Battery Roundup"

Sunshine Changing the World

As an electronics editor, I am constantly being briefed on new technologies. Often, the presenter struggles to establish a framework for the innovation being described, trying to make a case for the big-picture importance of what they’re doing. Seldom am I left with a feeling that I am learning about an engineering development that could truly change the world.

This, however, was … Read More → "Sunshine Changing the World"

When faced with the need for more of something, one possible solution is expansion. This could take many forms but one simple way is extending it to be greater in size, such as adding the dining room table leaves to fit more people around the Thanksgiving table. Samtec’s...

“Mommy, Daddy … Why is the sky blue?” As you scramble for an answer that lies somewhere between a discussion of refraction in gasses and “Oh, look—a doggie!” you already know the response to whatever you say will be a horrifyingly sincere “B...
