Designing for Movement

What is the difference between electronics in a robot vs., say, a stationary temperature monitor and control device? For one, if the temperature controller goes haywire, you can pull it off the wall and stomp on it, while you might... Read more

How Much of that part number is important?

Part numbers are incredibly important, but can also be incredibly annoying and confusing. Obviously, we all need them, but it would be nice if there were some semblance of a standard. Well, there are some standards, like capacitor grades and... Read more

Is it time for USB Type C?

The USB 3.1, type C standard have been around long enough such that the connectors and chips are readily available. But, it's a more complex set up and may have far more capabilities than is needed in your design. As... Read more

What Route Do You Take?

There are a lot of polar opposites in the "what is my philosophy" world: Mac vs. PC, on shore vs. off shore manufacturing, Ford vs. Chevy, Atmel vs. Microchip (well, maybe not that one so much any more), auto router... Read more

Top 5 Things to Know When Moving from Hand Assembly to Robotic Assembly

A lot of factors go into the decision to hand build or outsource circuit boards. I hand build my own sometimes, simply because I enjoy the challenge. Of course most of the projects I design are for my own use,... Read more

USB Type-C Connectors

It wasn't terribly long ago that pretty much every cell phone came out with its own custom charging cable. It was a major step forward when they all (except Apple) standardized on the USB micro-B connector. However, there are a... Read more

Using the Newest gen ARM, Part III

The continuing saga of the 0.4 mm pitch KL03 ARM microcontroller. If you haven't yet done so, read part I, and part II. Today, I have a look at the good, the bad, and the ugly - or more accurately,... Read more

USING THE NEWEST GEN ARM, Part II

I'm a bit behind in my blog work - well, way behind, actually. I started this series back in January with the intro post. Here's where I am right now: I have three different sets of PC boards. One set,... Read more

Using the Newest gen ARM Microcontrollers

I've written a few times about the new Freescale KL03 ARM Cortex M0+ microcontroller. This particular part comes only in very small packages, with the smallest being a 1.6mm x 2mm WLCSP (wafer level, chip scale package) 0.4mm pitch, 20... Read more

Polarized non-polarized components: Inductors

We have a number of manufacturing engineers running around here at Screaming Circuits. They're very good at what they do, as are our operators and technicians. They are not, however, electrical engineers. Our parent company has a big group of... Read more
