Free New Article: 8-Channel Timer with OLED Display -- UPDATED

With the compliments of the Elektor Editorial and Labs teams, here is a 'fresh' article presented free of charge to all Elektor e-zine subscribers. This time we have author Willem Tak discuss an upgrade to an earlier project publication. Willem was prompted by non-availability of a few, let's say, key components. We really like reader's contributions describing how published projects get enhanced, updated and tweaked so here goes with suggestions for new components, and software to put in the 2018 "Multi-Timer".

Using Precision Current Sensing to Optimize System Performance

There is a tremendous amount of pressure on the embedded electronics community for higher efficiencies and better system performance. This is due to multiple factors – from thermal management issues, to increased power densities, to battery life, and more. This pressure to improve is driving development in many areas. Much of the focus today is on advanced materials, topologies, and advanced software-defined architectures.

Particulate Matter Sensing for Air Quality – Measurements

Sensirion’s dust resistance and advanced binning technologies provide added value to applications in several industries, including air quality monitoring, air purifiers and HVAC. A sensor that works over the whole lifetime of a device guarantees good air quality to the final user and increases energy efficiency and sustainable operation. Advanced binning and higher accuracy help to trigger specific actions based on the detected particle composition and improve the monitoring of filter lifetime based on the contaminant type information collected over the device’s operation.

Understanding Ramifications of DDR5 Transmitter Test

DDR5 is a game changer in DDR memory technology. DDR5 is designed to satisfy large performance demands for data centers. Several key drivers for this technology are smart mobile technology and exascale computing. CPUs in the server and high computing industries are each fueled by GBs of memory. Technologies such as IoT, 100/400GBE and 5G are now connecting the world in real time. Storage architecture has been redefined with nonvolatile memory moving closer to the CPU. Also, the rise of new technology spaces like artificial intelligence and machine learning are defining the role of memory today.

Qt for the Raspberry Pi – A step by step guide to set up the GUI framework

Elektor software developer and lab worker Mathias Claußen was tasked to develop a control for the FM radio on the Raspberry Pi [1] using a touch screen. The platform-independent (GUI) framework Qt has almost become the go-to industry standard to build such interfaces, so the choice was clear. For any developers out there facing similar challenges, Mathias has put together a manual that shows how set up a cross-compiler environment on a PC to allow you to compile Qt applications for the Raspberry Pi from a PC — he also includes a simple demo of course.
