This article reviews some recent developments that are creating new optimised solutions across a range of applications.
The Internet of Things, IoT is coming to fruition even now, but what will it look like when it fully appears and what components will be needed for all the different nodes, sensors and actuators being developed.
Consumer preferences drive the silicon industry. Each generation of mobile phones has to be thinner than the last. The same scenario happens with computers, as consumers demand more speed. These market forces have led to further and further shrinkage in silicon geometries, as consumer device manufacturers try to push the boundaries of silicon performance.
Jeff Hastings of BrightSign has some interesting ideas on why fans should not be used in digital signage, and how to avoid using them.
Maxine Hewitt of Alpha Micro Components looks at how ready designed and built RF modules can help bring connected products for the Internet of Things to market faster.
Gone are the days of rotary switches, push buttons and seven segment displays. Incorporating touch screen displays into embedded designs is the trend, accelerated of course by consumer adoption of the smartphone.
Scott Soong of Pervasive Displays discusses how e-paper technology is contributing to the world of makers rather than just major companies enabling makers to utilise its advantages in projects based around Raspberry Pi and other single board computers.
The issue of counterfeit electronic components is one that has troubles the electronics industry - using them can have some major issues, everything from being removed from a preferred suppliers list to a reduction in quality.
