Newport Family of SBC Based on the Cavium Octeon 64-bit ARMv8 Processor

Posted on by mixos

Gateworks Corporation announces the Newport Family of single board computers featuring eight standard models. These models range in size and features to provide a comprehensive and flexible solution to customers requiring a high performance, feature-rich embedded networking board. The Newport Family is based upon the Cavium Octeon TX 64-bit ARMv8 SoC, which has been designed specifically for high performance networking applications. The Newport Family of boards offers processors ranging from an 800MHz Dual Core up to a 1.5GHz Quad Core. The Octeon TX features large L1/L2 caches, rich I/O with support for the latest standards (PCIe Gen 3, SATA3.0, USB 3.0, DDR4), security and networking acceleration engines, hardware virtualization, low power (<4W) and IPSec performance of 8Gbps with only 2-cores.

7 Undiscovered Add-On Boards For Your Raspberry Pi

Posted on by mixos

averagemanvsraspberrypi.com has a list of 7 add-on boards that you may not be aware of. They write:

It’s been a couple of weeks since I returned to the Pi, and I’m already seeing people using the same old default add-on boards all over the internet. Don’t get me wrong – they’re popular because they’re good quality, useful and affordable – but they don’t excite me.

What does excite me is when I find small batches of weird little wonders lurking in the dark, dingy alleyways of the internet. Odd little boards from different places, in different colours with different features.

They’re not mass-market, they’re not easy to find, and they’re usually not as cheap as mainstream options – but they are different – and that makes them interesting.

XTRX – Easily embeddable software-defined radio

Posted on by mixos

The first ever truly embedded SDR is live on crowdsupply.com

XTRX is the smallest, easily embeddable software-defined radio (SDR). It is both affordable and high-performance. Its professional-grade, drop-in technology is designed to enable the next generation of wireless solutions, from prototype to production.

While LTE modems and GPS receivers are commodity parts easily bought from your favorite electronic components store and added to your project, in order to embed an SDR you would have to spend precious time and money on a custom design – until now. With XTRX, you can easily embed an SDR and stay focused on what your customers really need.

Teardown & Repair of a SRS DS345 30MHz Synthesized Function Generator

Posted on by mixos

In this episode Shahriar investigates a peculiar problem with a SRS DS345 function generator. The instrument does not appear to produce the correct output signal frequency. After some investigation it becomes clear that a few of the display digits are not active which hide the actual frequency settings. The problem is traced to a broken resistor on the display driver. The schematic of the instrument shows that the resistor is responsible for strobing the affected seven-segment digit. After the repair, the instrument’s performance is verified including the OCXO accuracy.

Nanotechnology plays an indispensable role in modern materials research and new products. Carbon nanotubes (CNTs) enable production of novel materials with amazing properties. Progress is however not without risk and a recent study on mice has shown that certain types of CNTs have similar carcinogenic properties as asbestos fibers.

Wi-Lamp, the Open Source Wi-Fi LED lamp

Posted on by mixos

LucaBellan @ open-electronics.org discuss about a multi-function LED lamp that is always connected over WiFi.

Since several years already, it is possible to find systems for home automation: irrigation, doors and windows, lighting, air conditioning and alarm systems, everything can be centralized and planned. Recently, the classical control boxes have been replaced by smart systems that are always connected to the Wi-Fi Network and that can be remotely accessed by means of mobile devices such as smartphones or tablets.
