A technical performance-based view of opto-isolators and digital isolators | EDN

https://www.edn.com/design/analog/4461000/A-technical-performance-based-view-of-opto-isolators-and-digital-isolators Galvanic isolators are devices that couple an electrical data or control signal across an insulation barrier without any flow of current through it, thereby enabling signals to be transferred while blocking noise. The insulation barrier also safeguards equipment and human operators from high voltages. The earliest isolators were optically coupled devices, also called opto-isolators

CircuitPython on Raspberry Pi

https://blog.adafruit.com/2018/08/15/circuitpython-on-raspberry-pi-updated-guides-for-ads1x15-bme680-mcp4725-tsl2561-tsl2591/ It’s CircuitPython on Raspberry Pi! Wire up your favorite sensors and use the same CircuitPython code you’ve been using with microcontrollers right on your Raspberry Pi! Adafruit provides many projects, libraries and example code for CircuitPython on microcontrollers. Python is pretty easy to get it working with micro-computers like Raspberry Pi or other ‘Linux

4 tools for building embedded Linux systems

https://opensource.com/article/18/6/embedded-linux-build-tools Explore Yocto, Buildroot, OpenWRT, and adapted desktop distros to determine the right option for your project. The development environment in embedded systems programming is usually very different from the testing and production environments. Typically, the build output will consist of an entire software image for the target device, including the kernel, device drivers, libraries,

Microsoft built its own custom Linux kernel for its new IoT service | TechCrunch

https://techcrunch.com/2018/04/16/microsoft-built-its-own-custom-linux-kernel-for-its-new-iot-service/ Microsoft announced the launch of a secure end-to-end IoT product that focuses on microcontroller-based devices. At the core of Azure Sphere is a new class of certified MCUs. MediaTek is producing the first set of these new MCUs (single-core ARM-A7 systems that run at 500MHz). Interesring twist is that for the first time ever,

Hot wheels speed sensor

I built a Hot Wheels toy car track speed sensor using Arduino and metal detector. The main processing unit is Arduino Uno + sensor shield on top of it.  The display is cheap LCD display that connects to I2C. The sensor is metal detector kit I tested and converted to Arduino sensor in Metal detector

Embedded Conference Finland 2018

Embedded Comference Finland 2018 was on Helsinki today.Security was still hot topic again this year because many companies have not fixed their Internet of Threats products.The outcome was that the trend is that third parties will almost always make your IoT products less secure than you made them to be.
