Happy National Coffee Day! I've been told that much of the world economy exists only because of coffee. That's a bit of hyperbole, but I'm going to have to say that it's accurate hyperbole. @Atmel tweeted a diagram describing the... Continue reading

Surface mount assembly robots are amazing machines. Not long ago, I read that the pick and place heads in the fastest, highest volume SMT machines travel so fast, that they are just short of supersonic. The placement logic takes into... Continue reading

September is usually a decent month to be in Minnesota. The snows haven't arrived, and the summer thunderstorms are past - well, usually. Last night, the lightning looked like a 1970's disco strobe light, and the rain was so intense... Continue reading

Most of us have heard the quote: "The definition of insanity is doing something over and over again and expecting a different result." It's generally attributed to Albert Einstein, but there's enough contrary "evidence" to cast doubt on that attribution.... Continue reading

Am I a broken record? Pretty much - especially when it comes to confusing diode marketing. For example, everyone knows what the diode symbol looks like, and pretty much everyone knows which side is the anode and which is the... Continue reading

The first answer to that question is probably going to be along the lines of: "put them on the board." But, sometimes you can't have reference designators on your board. Maybe it's too densely populated and there isn't room. Maybe,... Continue reading

So, dancing robots are now in the Guinness Book of Records. Not too many things can compete in the category of "dancing robots", so a world record is not all that impressive a feat. Of course, when you're talking over... Continue reading

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... Continue reading

I've recently spent some time getting familiar with the Intel Edison. The Edison has a dual-core 500 MHZ Intel Atom processor, with built-in Wi-Fi and Bluetooth. It comes with 1GB of RAM, 4GB of eMMC internal storage, and a USB... Continue reading

Here at Screaming Circuits, we assemble PCBs for a lot of interesting organizations. Perhaps one of the most interesting is LIGO (Laser Interferometer Gravity Wave Observatory). In case you've been busy with Pokemon GO for the last few months, and... Continue reading

Many small quantity PC boards are ordered individually cut. They come to us as a set of unconnected boards. For small quantities of reasonable size boards, it makes the most sense to order them this way. However, for really small... Continue reading

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,... Continue reading

One of the handy aspects of getting boards assembled at Screaming Circuits is that we don't require fiducial marks for standard process boards. I would say that we build far more boards without fiducials than with. That's cool, but there... Continue reading

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... Continue reading

I've given a few talks at the various Embedded Systems Conferences on the subject of the Arduino as a real prototyping tool. I've designed and built a number of custom Arduino-compatible boards myself. I've become an advocate for the Arduino... Continue reading

In honor of St Patrick's day and all things green, I give you the PCB... And some trivia. You may have noticed that the soldermask used on most PC boards is green, as is the paint used on most steel... Continue reading
