Your Mileage (and Other Things) May Vary Barry Manz
The practice of taking liberties with performance specifications to show a product in its best light is obviously nothing new in the electronics industry, and many others as well. If you’re old enough to remember, the output of stereo amplifiers and receivers was rated as “peak power”, which is typically five or six times higher than RMS power, but for the anointed it certainly makes the amplifier appear to be a real powerhouse. The output power of RF power transistors is even today sometimes specified at a single frequency where it’s highest, even though it falls off below and above it. And so on.

You Can Actually Bake Some Electronics in the Oven, if You Want Nicolette Emmino
Have you ever had the urge to boil your iPhone SE in water, torch your iPhone 6 at a temperature of 6,000° F, or bake your iPhone 5S inside of a cake at 350° F? In case you needed me to tell you, don’t do it.

Developing Communications and Mapping for a New Generation of Driverless Cars Pedro Calomarde
A new generation of driverless vehicles is dramatically changing the way automotive systems are designed and built. These driverless car systems will have significantly increased communication capability, linking vehicles together on the road and back to the cloud. All of this will be controlled by high end processors with complex 3D mapping and control algorithms, and all of this needs to be made secure.

7 things to know about spacecraft subsystems before your next trip to Mars Texas Instruments
When I was young, as most aspiring engineers do, I dreamed of going to outer space, specifically Mars. And I thought the only way to get there was aboard the NASA space shuttle. The cancellation of the shuttle program crushed that boyhood dream of mine, or so I thought. The recent commercialization of satellites and launch services, that may someday provide space exploration, has kept that dream alive for all of us. With some new innovation and the decades of experience out there I believe they will be able to make this dream a reality.

How to Choose a Controller for Motor Applications Bill Schweber
Choosing the type of control to use for various motor applications is a strategic choice that should be made before selecting a specific vendor or model. This is because there are many trade-offs when deciding to use a general-purpose processor that is well-suited for motor control, a computation-friendly FPGA, or a dedicated control IC (the latter is most often from a specialized motion-control vendor).

Autopilot vs. Autonomous Lynnette Reese
People have misperceptions about autonomy. Autopilots have been used in aircraft for decades. In newer planes and at properly equipped airports, the autopilot can also be used for landing, usually in dense fog with lots of radar equipment on the plane and on the ground, and the landing isn’t gentle. (Pilots occasionally perform a “greased in” landing, which is when touch down is so gentle you don’t even feel it. Be sure to congratulate your pilot if this ever happens.)

Desktop Factories: A ‘Moving’ Look at 3D Printing Mike Parks
There is no other product that singularly captures the essence of the maker movement more than the 3D printer. It is difficult to describe the feeling you get when you use a 3D printer for the first time. It truly is a euphoric rush once you realize you have the ability to take a mere concept in your mind’s eye and bring it to a tangible reality. There are many technologies driving the plethora of additive manufacturing products available today including stereolithography, Selective Laser Sintering (SLS), Electron Beam Melting (EBM) and the most universally recognized Fused Filament Fabrication (FFF) method.

MCU Sleep States: How Many Do You Really Need? Warren Miller
MCUs have found homes in just about every low power application. The ability for the MCU to enter a low power mode has made them even more attractive in a variety of power restricted designs. Recent advances in energy harvesting have created new opportunities for MCU controlled devices, and low power is critical here, too. In fact, energy harvesting presents bigger challenges than battery operated applications since power isn’t available in as predictable a manner as with batteries.

Vehicle Lighting with LEDs Arden Henderson
Light Emitting Diode (LED) illumination is everywhere now. Though a slow start due to cost, LED lighting[0] is less costly now, ever so more versatile, and is scaling up rapidly in applications for homes, businesses, signage, and automotive applications, for starters.

Pick any reality, and teleport there with VR Mark Patrick
The many reality technologies to pick from let us escape to a virtual or semi-virtual world, but with telehaptics we can get even more jacked in and get as close possible to that ultimate Star Trek geek-out: teleportation.
