I recommend the ZigBee protocol only when a design requires interoperability with other ZigBee devices, or when someone wants a ZigBee certification. For proprietary designs or basic wireless communications, modules that operate to the IEEE 802.15.4 standard will do a nice job without the software overhead ZigBee requires.
I was once very interested in those TI 802.15.4 SoCs, but those currently in production use an 8051 core and to do anything useful with them requires a heafy investment in development tools (eg IAR which costs 2-3k$). No thank you, ARM for me please.
Earlier this year paralyzed IndyCar drive Sam Schmidt did the seemingly impossible -- opening the qualifying rounds at Indy by driving a modified Corvette C7 Stingray around the Indianapolis Motor Speedway.
Wearables are changing the way we see ourselves. With onboard sensors that have access to our bodies, we are starting to know our physical selves like never before, quantifying our activity, our heart rate, breathing, and even our muscle effort.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
This year, Design News is getting a head start on the Fourth of July celebration. In honor of our country and its legacy of engineering innovation -- in all of its forms -- we are taking you on an alphabetical tour through all 50 states to showcase interesting engineering breakthroughs and historically significant events.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
