Engineering Snobs Lynnette Reese
I try not to be a snob. Early on in my engineering career, I was taken down a peg or two after graduation. I had this shiny new degree I was ready to try out, but engineering is a lot more than academic knowledge. After a few months of working, I realized that there was a large amount that I did not know. All the subjects I took were preparing me to be an engineer. But you cannot discount the learning associated with doing.

Samsung’s 60-GHz Wi-Fi Announcement Deciphered Barry Manz
Perhaps, lost amid the recent uproar about new smartphones and phablets for the holidays, was Samsung’s announcement that it has revolutionized Wi-Fi by operating at 60 GHz. That and the enhancements Samsung says it has made allow performance using the IEEE 802.11ad protocol to deliver massive speed increases over existing Wi-Fi –transferring a 1-Gbyte file in less than 3 seconds. This obviously sounds like a Samsung-only accomplishment, and in some ways, it is. But it helps to get the whole picture.

Is it High Time for High Resolution? David Whittle
Recently I attended the 137th Audio Engineering Society (AES) Convention in Los Angeles. If you aren’t familiar with the AES Convention it’s a small event that hosts a pro audio trade show along with a wide range of technical sessions for design engineers developing new audio products. This year the AES technical programs featured a product design track that covered networked audio, analog-to-digital (A/D) and Digital-to-Analog (D/A) design for high-resolution audio (HRA). Some of the best producers, recording engineers, and audio hardware designers in the world attend to participate in workshops and make themselves available for questions. If you’re designing products that include audio and have never attended the convention you might want to consider looking into next year’s convention.

How to Think Creatively About Your Next Design Justin Risedorf
From sliced bread to rocket ships, people have shown their creative nature throughout history by designing new things. Not surprisingly, many of the greatest designs came about as the answer to a problem. Gravity got you down? The Wright brothers have a solution. Computers too big? Kilby and Noyce introduce the world to microchips (and Silicon Valley in the process). Want to do more with a peanut? George Washington Carver has around three hundred good ideas. But these guys are the stuff of legends. Do ordinary folk like you and I have the ability to think creatively too?

AS6496 Anti-Counterfeit Control Plan Posted Chuck Amsden
The AS6496 standard was published in August and Mouser now has an Anti-Counterfeit Control Plan written specifically to that standard.

Seeing The Light: A Circuit For Interfacing With Ambient Light Sensors Mike Parks
We built a smart mailbox, as related in an article, that had an ambient light sensor to detect when the mailbox door was opened. In that project we used a Vishay ambient light sensor (Mouser Part #782-TEPT4400) that acts very much like an NPN transistor, in fact the part is also referred to as a phototransistor. The difference being (when compared to a normal bipolar junction transistor) that instead of needing a base lead to setup the bias voltage, photons provide energy at the base-collector junction to turn the transistor on, thus allowing current flow from collector-to-emitter.
