Weekend Wisdom - The next big thing

In the 1970s and '80s, digital electronics was exploding just below the surface of public awareness. Early adopters were starting to use it, mainstream media was starting to report on it (usually with little understanding of what they were writing... Read more

A question on Schematic Parts Placement

A question on Schematic Parts Placement
Question for the day: Where do the bypass capacitors go? We all know that, on the finished PC board, bypass capacitors need to be strategically located close to chips and noise sources, but what about on the schematic? In this... Read more

Screaming Circuits "Teardown" Virtual Factory Tour

I make no secret of the fact that I'm a big fan of electronics. I've been around R's, C's, L's, Q's and U's long enough that the first PC boards I soldered up were hand etched by me with supplies... Read more

Beware open vias near pads

Beware open vias near pads
Having open vias in pads is just about the number one "do not do" when creating a printed circuit board. Number two or three is don't have open vias near pads without a solder mask dam to stop the flow... Read more

Law of Conservation of Parts

Law of Conservation of Parts
Reels of parts are the way to go when you need a lot of boards built. It's just not practical to deal with a bunch of cut strips when building hundreds or thousands of boards. It's even easier to use... Read more

One Library Per Design

One Library Per Design
There was a time when I relied pretty heavily on the libraries that came with my CAD software. At first, I exclusively used what came with the package. Next, I started downloading libraries for new components from user contributed content.... Read more

Weekend Wisdom - Is the age of Gerber over?
I have in my bookshelf, an autographed copy of "The Inventor's Dilemma, The Remarkable Life of H. Joseph Gerber." I purchased the book, written by the subject's son, David Gerber, in early April 2016 with the knowledge that I would... Read more

Single Node Nets

Single Node Nets
I've read various opinions on schematic technique regarding the illustration of nets and nodes. Some folks want to route as much as is possible with net lines and some folks think it's clearer to use a lot of node symbols... Read more

PCB Assembly vs. Mondayitis

PCB Assembly vs. Mondayitis
I pulled up an older MCU and motor driver board of mine this morning. It's a project from about ten years ago that I haven't had built since 2016. It's still a nice design. In 1.3" x 2", I have... Read more

Angst and Anxiety in Electronics Design

Angst and Anxiety in Electronics Design
I've been called many things: Spock, Sheldon, weird, nerd, dork - probably too many names to list, and some not fit for print. The names aren't the point of this article, but the angst and anxiety that comes along with... Read more
