Adding a wireless interface is easy. You just buy one of the black-box solutions available from countless vendors, and you drop it into your system. An adjustment here, a tweak there, some minimal testing procedures provided by the wireless vendor, and you're all set. Or are you?
Generally, communicating with similar devices (or those that deploy wireless components from one vendor) offers seamless connections. But the beauty of designing to a standard, in theory at least, is that all these devices will talk to one another after a simple pairing process.
If you've ever actually tried to design in a wireless medium, you know that that's usually far from reality. In fact, the testing of wireless networks can often be a long, arduous, head-scratching process. To that end, Design News' Continuing Education Center, sponsored by Digi-Key, is hosting a series of classes that will simplify the process for you. The classes, aptly named "Testing Wireless Devices & Systems," begin on Monday, July 9, and run for five days.
Whether you were aware or not, there's more to testing than meets the eye. Just because your prototype operates properly doesn't mean the final production model will operate similarly according to design. You will learn through hard work -- and patience -- how much wiggle room there is, depending on your medium of choice, your application, your budget, and a bunch of other characteristics.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
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.
