Bench Talk

Sometimes I feel the need to disappear, to suddenly pick up and leave – especially at those times when I feel the world is spinning just a little too fast. To slow it down, I find the perfect getaway vehicle is a car and an open road. It’s just the thing to clear my head and open myself up to new ways of thinking.

Many integrated circuit-based sensors and output devices offer an interface protocol called Inter-integrated Circuit, commonly abbreviated as I2C. There is tremendous value in using I2C-based components in a microcontroller-based solution that can result in a much more streamlined and robust product, especially if you need to interface with multiple external I/O devices. I2C allows you to share a common data and clock bus amongst multiple devices, thus reducing the I/O pin count and the number of interconnecting wires required to get everything communicating. This blog is an attempt to provide some practical tips on integrating I2C into your next application.

Robots are nothing new to the sci-fi genre. From servants like Robby the Robot in Forbidden Planet and The Jetson’s sassy maid Rosie, to noble, innocent machines like Johnny 5 and Data, robots seem to be everywhere in entertainment. But back in the day, actually interacting with one of these creations in real life seemed like, well, science fiction. But today, many of us interact with robots on a daily basis without giving it a second thought.

You’ve heard of the Love Boat, but have you heard of the Love Bot? Many romance seekers at the recent SXSW festival in Austin, Texas, were tricked into opening their hearts and pouring out their feelings to what turned out to be nothing more than Artificial Intelligence (A.I.) on the popular dating app Tinder.

USB-powered spectrum analyzers aren’t new and some are truly tiny -- just a bit bigger than a flash drive. Some have surprisingly good performance over very wide frequency ranges. The least expensive of these “instruments in a stick” is less than $100. However, every once in a while one comes along that reshuffles the deck, and the latest is the RSA306 from Tektronix. While I rarely extol the virtues of any signal product in these blogs, this one has some features that make it very interesting and suited for applications that are way beyond what instruments like this are typically used for.

Your intrepid reporter, a veritable APEC ingénue, felt compelled to take part in the long-held tradition at APEC: Three concurrent RAP sessions closed out on Day 1. The RAP sessions are composed of a moderator, some apparently famous power panelists, topics that foster lively (geek-bait) debates, and historically large audiences blessed with a beer on their way in. The sessions drew large crowds. (Or was it the free beer?)

If you weren’t certain by Day 1 of the Applied Power Electronics Conference (APEC) exhibition what the running themes were, you found confirmation on Day 2. High density, low power, SiC and GaN all played out through new products, technical sessions, and papers.

The Charlotte, North Carolina Convention Center, home to APEC 2015, is a decent size. But with nearly 4500 attendees (a 10% increase over last year), hundreds of technical and industry sessions, and nearly 250 exhibitors, it certainly packed a lot into one space.

I thoroughly enjoy going to the Perot Museum of Nature and Science. I have gone many times with friends, family and dates. Going by myself is OK. Going with someone interested in STEM (Science, Technology and Math) is enjoyable, but going with someone with lots of energy and not as much scientific knowledge is the best.

Predicting the future of technology is a perpetual exercise in futility. But it’s fun. The evolution of personal computing is something that futurists and tech pundits like to try to predict every few years (or months). Like forecasting the weather, you are never completely right or wrong.
