Intel NUC 9 Extreme “Ghost Canyon” Kit – NUC9i9QNX Review

I’ve previously written about Intel’s (relatively) new NUC 9 range of mini PCs and now I am following up with my experiences of having bought one. Whilst I’ll cover some performance metrics from both Windows and Ubuntu I’ll also discuss the benefits and drawbacks of using either OS together with a comparison of gaming, thermals, and power usage as well as a brief look at overclocking potential and implications together with highlighting the issues encountered. NUC9i9QNX Hardware Overview The model I purchased and will be reviewing here is the NUC9i9QNX from Intel’s Ghost Canyon lineup and is formally known as the Intel NUC 9 Extreme Kit – NUC9i9QNX. It contains a “Compute Element” with an i9-9980HK which is an eight-core 16-thread 2.40 GHz processor boosting to 5.00 GHz with Intel’s UHD Graphics 630. The full specifications of the NUC9i9QNX include: The NUC9i9QNX is sold as a kit which essentially means […]

How to Take a Remote Screenshot in Raspberry Pi over SSH

I recently reviewed a Raspberry Pi 4 laptop with a custom interface that made it impractical to take screenshots directly on the device. So instead I had to take screenshots remotely over SSH. It’s quite easy to do. Most of the steps can be reproduced in other Linux systems, and are not specific to Raspberry Pi. Enable SSH in Raspberry Pi First, enable SSH either with sudo raspi-config in a terminal window and selecting 5. Interface Options, then P2 SSH… If for some reason, you don’t have access to the terminal, take out the MicroSD card from the Raspberry Pi board, and from a computer create a new empty file named “ssh” in the boot partition. Now provided you have the username and password for your board, you can connect to SSH with the IP address from a terminal:

ssh <username>@<ip_address>

1	ssh <username>@<ip_address>

or a program like Putty. Taking a screenshot remotely You’re […]

USBImager – A Lightweight Alternative to balenaEtcher

The common way to flash OS images to SD cards used to be “dd”. But you could potentially damage your system with a wrong command, it will not do verification after writing the firmware image, and it was not available in Windows, so people had to use Win32DiskImager, and last time I check it did not do verification either. So Etcher, now called balenaEtcher, became a popular cross-operating systems tool to flash images for Raspberry Pi and other SBCs. It’s easy to use and does verification after flashing. However, the binary is rather large at around 130 MB, and the company started to show sponsors to fund the development of the program, and this was not to the liking of everyone. During my review of CrowPi2 Raspberry Pi 4 laptop, I encountered an issue with balenaEtcher, which was quickly fixed once I updated the program to the latest version. But […]

CrowPi2 Raspberry Pi 4 Education Laptop Review

I started my review of CrowPi2 Raspberry Pi 4 Learning Kit a while ago and at the time I showed content from the kit and its first boot. I’ve now spent more time with this very special Raspberry Pi 4 laptop and will focus this review on the education part, namely CrowPi2 software, but will also look at thermal cooling under stress with and without a fan, and try to install another Raspberry Pi compatible board inside the laptop shell. CrowPi2 Education Software It’s quite important to read the user manual before getting started as there are a few non-intuitive steps you may have to take. First I assume the wireless keyboard would just connect after pressing the power button, but it did not. The user manual explains the RF dongle is inside the mouse, and once you connect it you’ll be able to use the keyboard that has some […]

Testing Hercules OTT Realtek RTD1395 4K Android STB Development Board

This is a guest post by Promwad, a software and hardware product development company with DTV & STB development expertise and know-how. Recently, they received a package from Realtek, their partner in Taiwan. There was a Realtek RTD1395 development board inside – Hercules 32-bit OTT – with 2 GB RAM and pre-installed Android 9 OS. Promwad team tested what it’s capable of and how it can be used by hardware and software engineers who design new TV set-top boxes and develop embedded software. Hercules OTT board is an Android IPTV box that plays videos of any formats with a maximum resolution of 4K. Streaming services such as Youtube, Netflix, etc. are supported via Dash and HLS. Also, the board supports other Android apps, including audio/video calls and conferencing. Realtek introduced RTD1395-based boards back in 2018. IP and cable TV operators used them in their subscriber devices. The RTD1395 chip with […]

Review of FamiSafe Phone Tracking & Parental Control App (Sponsored)

CNXSoft here. I’ve been tasked with reviewing Famisafe parental control app for Android and iOS acting both as a parental control app and phone tracker app and designed for parents who want to track their kids’ location and better control when to use the phone and what content they may access. The first thing to get started is to download the free trial on either Android or iOS. I actually downloaded both versions for FamiSafe for this review, since I used Huawei Y9 Prime 2019 (Android 10) as the “parent” smartphone, and an iPhone 6 as the “kid” phone. Famisafe Initial Configuration We’ll have to start with the “parent” phone. After a welcome screen explaining some of the main features including offensive content detection, device & app usage rules, web filter, etc.. you’ll be asked to select whether it’s the parent or kid device. Once we select “Parent” we’ll be […]

Perfetto Profiler Now Supports Mali GPU Hardware Counters via Panfrost

Perfetto is an open-source system profiler, app tracer, and trace analyzer for Linux, Android & Chrome platforms, and user-space apps. The program can already visualize CPU and memory usage, as well as power consumption. GPU support is more limited with the program only capable of sampling the GPU frequency when the driver outputs that information via ftrace. When Perfetto is also extendable thanks to a Tracing C++ SDK that “allows userspace applications to emit trace events and add more app-specific context to a Perfetto trace”. Collabora made use of the tracing SDK to add support for Mali Midgard GPU performance profiling in gfx-pps project using the Mali GPU hardware counters exposed via Panfrost open-source Mali GPU driver. After following the installation instructions, you’ll be able to run the following executables for tracing and profiling: tracedtracing service. traced_probes OS probes service. perfetto command-line tool for recording traces. producer-gpuproviding the Panfrost data […]

NanoPi NEO3 and NanoPi R2S Gateways Review – Part 1: Unboxing & Teardown

This morning I received a message from DHL informing me of an incoming package from Hong Kong and sent by a company (i.e. an agent) I had never heard of. My first reaction was “Ah” shortly followed by “Why?!”. But in any case, I’ve just received the package, and after tearing the plastic out, I found a FriendlyELEC branded package. So I thought to myself it must be a NanoPi board for review. Wrong! I actually got two NanoPi “boards” namely NanoPi NEO3 with 2GB RAM, and NanoPi R2S both of which are Rockchip RK3328 powered SBC’s designed for Linux headless applications. Unboxing After opening both packages, I realized I did not get the SBC versions, but instead the complete gateways with their respective enclosure. NEO3 is really light since the case is in plastic, while R2S is a bit heavier due to the metal case. NanoPi NEO3 gateway comes […]
