PROTOTYPE AND SMALL VOLUME
PCB ASSEMBLY MADE EASY

So Long Old Friend

Just watching the final shuttle launch and pondering a few questions. A significant number of innovations came out of the Mercury, Gemini and Apollo programs and filtered down to public life. Some were in materials, some were in electronics, some... Read more

Loopy Ground Loops

A while back, I posed a question about using flood fill (AKA copper pours). I've been reading a lot about ground loops lately which brought me back to that original question. Some people suggest segmenting your ground plane between analog... Read more

Bouncing BGAs

I dropped my cell phone on the pavement the other day. That's bad enough, but in my instinctive attempt to catch it, I actually hit it and increased it's downward velocity. Luckily, everything still works. The odd thing is that... Read more

Hi Ho. Hi Ho. It's off to Scone I go

I found this video over on the adafruit blog. Asimo, by Honda, is cool. Mars rovers, by JPL, are cool. Packbots, by iRobot, are cool. But, for robots to really take off, they need to be able to run down... Read more

Twitter, What is it Good For? Absolutely 555contest

I follow a few people on Twitter. A few people follow me on Twitter. A number of web sites have engaged their readers in debates about the usefulness of Twitter (and other social media) to engineers. In general, these debates... Read more

0 or 1?

I've been running around telling people "Happy New Decade." Generally, such has been received with a blank stare or some comment related to me being sarcastic. Back when we turned from 1999 to 2000 and again from 2000 to 2001,... Read more

Open Source Mea Culpa or back pedaling? You decide

Last week I wrote about "Ten electronics things to be thankful for in 2010." If you're reading this now, you probably don't need the link because you probably read that article then too. But that's not really relevant. What is... Read more

Need a Reference for the Reference

Not long ago, I wrote a short post about non-standard use of reference designators. After doing that, I've been looking at some of my own microcontroller and motor driver boards with an eye for how close to standards I am.... Read more

Spam, Spam, Eggs and Spam

I normally expend most of my writing words on challenges our customers and other engineers might face in their day to day design and layout activities. But not today. Today, it's about a specific challenge faced by your typical blogger.... Read more

Reference Designators

Not a subject I give much thought to. For one, we here at Screaming Circuits don't really care too much what convention you use for your components. We want them to match and be properly formatted when in your BOM,... Read more
