Rock Pi 4B or Raspberry Pi 4 based mini PC runs RISC OS Cloverleaf (Crowdfunding)

First released in 1987 by Acorn Computer Ltd, RISC OS was the first operating system designed to run on ARM processors, and specifically on the company’s Archimedes personal computer. I don’t think I had ever heard about the operating systems until it was ported to the Raspberry Pi SBC by RISC OS Open Ltd (aka ROOL) who manage the publication of RISC OS source code. But there’s also a separate project called RISC OS Cloverleaf which aims to further develop the open-source operating systems, and just launched a Kickstarter campaign to fund software development, and they also offer two mini PCs running RISC OS Cloverleaf with namely Cloverleaf Puma powered by a Rock Pi 4B SBC, and Cloverleaf Kitten featuring a Raspberry Pi 4 board. Cloverleaf Puma / Kitten key features and specifications: SBC Cloverleaf Kitten – Raspberry Pi 4 with Broadcom BCM2711 SoC, 4GB DDR4 RAM Cloverleaf Puma – […]

Intel unveils eASIC N5X Structured ASIC, and the Open FPGA Stack

Intel’s virtual FPGA Technology Day 2020 is taking place today, and the company made two announcements before the event. First, the company introduced the new Intel eASIC N5X structured eASIC family with an Intel FPGA compatible hard processor system to design to quickly create applications across 5G, artificial intelligence, cloud, and edge workloads. In addition, Intel also announced the Intel Open FPGA Stack (aka Intel OFS), a scalable, open-source (intel calls it “source-accessible”) hardware and software infrastructure available through git repositories design to ease the work of hardware, software, and application developers. Intel eASIC N5X eASIC N5X is the first structure ASIC from the company to integrate an Intel FPGA compatible Quad-core Armv8 hard processor system. The new chips will help customers bring custom solutions faster to market compared to traditional ASICs thanks to the FPGA fabric, and at a cheaper cost and with up to 50% lower core power […]

ELBE is a simpler alternative to Yocto/OpenEmbedded and Buildroot

To support embedded design, there are several options when it comes to choosing an operating system (OS). Some of the traditional approaches to building custom Linux systems is to use built systems such as Yocto/OpenEmbedded or Buildroot. The options available for system integration include building everything manually, binary distributions (Debian, Ubuntu, Fedora, etc.), and build systems (Buildroot, Yocto, PTXdist, etc.). The major drawback of build systems is that they are not as easy as a binary distribution and also the build time is more. Why was ELBE born? In the early days, the embedded devices had 4MiB flash and 16MiB of RAM. With these specifications, people started to hack a root file system for their devices. But in some cases, they had to start with building a cross-toolchain first. For this, tools like OpenEmbedded, Buildroot are good as long as they are well maintained. For this, a lot of libraries […]

Reading Vehicle OBD-II data through CAN within a containerized application in Embedded Linux

telematics applications overview-GNSS CAN Cloud embedded Linux

CNXSoft: This is a guest about OBD-II and CAN support in embedded Linux by Andre Márcio de Lima Curvello, Sr. FAE and Technical Evangelist, Toradex A connected world makes it possible to track your online orders being shipped to your home through your smartphone in real-time, and getting information about your vehicle such as tire pressure, outside temperature, and even details like if a lamp is broken – has begun to be possible via smartphones in modern vehicle models. But behind the magic of knowing where the truck carrying your package is at all times and other details of the vehicle, there is a very complex world made of embedded devices ‘talking’ to each other so the information makes its way from the device to you. In this article, you will learn how to create an application to communicate with a vehicle through CAN via the OBD-II standard. We use […]

Reolink RLC-810A Smart 4K PoE IP Camera Specifications and Unboxing

Reolink RLC-810A Smart 4K PoE Camera Review

I have reviewed two Reolink WiFi IP cameras in recent years: Reolink Argus Eco and Reolink Argus PT. Both are powered by solar panels, and they’ve been running at home for many months, but there are many false positives, or on the contrary, sometimes the PIR sensor fails to detect people. What would solve this is built-in AI into those surveillance cameras. The good news is that Reolink RLC-810A does just that with the ability to detect persons and/or vehicles, so you would not receive a notification because some bird or insect flew in front of the camera. I’ve just received a review sample, so I’ll part by listing the specs and features, and unboxing the package to see what the camera looks like, and check out included accessories. Reolink RLC-810A specifications Video & Audio Image Sensor – 1/2.49″ CMOS Sensor Video Resolution – 3840×2160 (8.0 Megapixels) at 25 frames/sec […]

Kywoo Tycoon 3D Printer Unboxing and User Experience Review

Hey, Karl here. A lot of our readers know I do most, if not all of the 3D printer reviews for the site. I feel very fortunate to be able to review them. It does take quite a lot of time but sometimes a gem comes along. I was fortunate enough to be chosen to review and share with you a new printer from Kywoo. The Tycoon 3D printer ticks all the boxes I have been asking for. Easy assembly Direct Drive Linear motion (Rods and rails in this machine) Smooth filament holder Touch Screen Auto Bed leveling (Until now I didn’t know I wanted this…more on that later) Rock Solid frame There are a few shortcomings and I hope what I am sharing is addressed before the final shipment. I will go into more detail later on. As far as the physical printer I am super happy with the […]
