I’ve just received a 10.1-inch touchscreen display designed for Raspberry Pi model B boards with 1200×800 resolution from the EVICIV store on Amazon that also offers models with 1366×378 and 1920×1200 resolutions, and allows users to create an All-in-One computer based on the popular SBC. The product can also be used as a standalone display connected to an HDMI or USB-C (via DisplayPort Alt mode) source, so it could be interesting for all sorts of projects and not only ones relying on Raspberry Pi boards. In the first part of the review, I’ll check out the hardware, install a Raspberry Pi 4, and boot it to check out whether it works, before going into more details in the second part of the review.

Using MangoHud to check FPS, CPU & GPU usage on a ‘hackendeck’
Previously I followed Valve’s documentation to build a ‘hackendeck’ using a mini PC to emulate their highly anticipated Steam Deck. Interestingly the ‘hackendeck’ uses a Linux OS, specifically Manjaro, as whilst Valve based their earlier version of Steam OS on Debian, they have now switched to being based on Arch. If the ‘hackendeck’ had just been Steam on Windows then to review gaming performance I’d just use MSI Afterburner. Until now, however, for Linux, I’ve always had to estimate the average FPS as I’ve not been aware of a good reliable equivalent. Fortunately several ‘commenters’ recommended using MangoHud, a Linux open-source Vulkan/OpenGL overlay for monitoring FPS, CPU/GPU usage, and temperatures similar to MSI Afterburner. So now I’ve been able to capture the average frame rate for the games I previously tested and I’ll present them below. MangoHud Installation and configuration The installation of MangoHud was extremely simple. First I installed […]
Save the planet! Program in C, avoid Python, Perl
As a former software engineer who’s mostly worked with C programming, and to a lesser extent assembler, I know in my heart that those are the two most efficient programming languages since they are so close to the hardware. But to remove any doubts, a team of Portuguese university researchers attempted to quantify the energy efficiency of different programming languages (and of their compiler/interpreter) in a paper entitled Energy Efficiency across Programming Languages published in 2017, where they looked at the runtime, memory usage, and energy consumption of twenty-seven well-known programming languages. C is the uncontested winner here being the most efficient, while Python, which I’ll now call the polluters’ programming language :), is right at the bottom of the scale together with Perl. The study goes through the methodology and various benchmarks, but let’s pick the binary-trees results to illustrate the point starting with compiled code. To the surprise […]
Photon Mono X resin 3D printer review with Wash and Cure Plus Machine – Unboxing and First Prints
Hey, Karl here. Today we are going to unbox and take a look at Anycubic’s Photon Mono X resin 3D printer and Wash and Cure Plus machine. The Mono X is what I would consider a medium size resin 3D printer that boasts a 192x120x245 build volume. Mono is included in the name because they have changed to a mono screen. They say there are 2 advantages when using a mono screen. 1 the screen lasts longer compared to an RGB screen and 2 it allows more light through allowing for faster prints. I won’t go into much detail as I believe most people are aware of this 3D printing method. In summary, UV reactive resin is cured layer by layer until a model is printed. The typical layer height of .05mm vs a typical .2 layer height for FDM printing allows for high detail printing and the layers are […]
COM Express Type 6 module supports up to 64GB ECC RAM, 2.5GbE, 4 displays, and more
Here’s another Tiger Lake UP3 COM Express module courtesy of AAEON with the COM-TGUC6 COM Express Compact Type 6 modules equipped with a choice of Celeron. Core i3/i5/i7 embedded processors from the 11th generation Tiger Lake family. The module supports up to 64 GB ECC RAM via two SO-DIMM sockets, 2.5 Gpbs Ethernet, up to four independent displays via LVDS, VGA, and 4K DDI interfaces, SATA storage, PCIe Gen 3 & Gen4, and more for industrial. medical, and military applications. COM-TGUC6 specifications: Tiger Lake UP3 SoC (one or the other) Intel Core i7-1185G7E/GRE quad-core/octa-thread processor @ 1.8/4.4 GHz with 12 MB cache, 96 EU Intel Iris Xe graphics; TDP: 15W (Up to 28W) Intel Core i7-1145G7E/GRE quad-core/octa-thread processor @ 1.5/4.1 GHz with 8 MB cache, 80 EU Intel Iris Xe graphics; TDP: 15W (Up to 28W) Intel Core i3-1115G4E/GRE dual-core/quad-thread processor @ 2.2/3.9 GHz with 6 MB cache, 48 EU […]
Orange Pi R1 Plus LTS is a cheaper dual GbE SBC with YT8531C Ethernet transceiver
It’s been a while since Shenzhen Xunlong Software released a new Orange Pi board. But the wait is over… sort of, as Orange Pi R1 Plus LTS is a low-cost version of Orange Pi R1 Plus SBC that replaced the Realtek RTL8211E PHY with a YT8531C Ethernet PHY that offers the exact same features but at a lower price. That means the new single board computer is still designed for headless operation, for example a router or firewall, with a Rockchip RK3328 processor, 1GB RAM, dual Gigabit Ethernet, and a USB 2.0 port. Orange Pi R1 Plus LTS specifications: SoC – Rockchip RK3328 quad-core Cortex-A53 @ 1.5 GHz with Arm Mali-450MP2 System Memory – 1GB LPDDR3 RAM Storage – MicroSD card slot, 16 MB SPI flash Connectivity – 2x Gigabit Ethernet via YT8531C Ethernet PHY and RTL8153B USB 3.0 to Ethernet chip USB – 1x USB 2.0 port, 1x USB-C OTG […]
Hardware security flaw impacts Intel Apollo Lake & Gemini Lake processors
A few years go the Spectre and Meltdown hardware security vulnerabilities impacted a wide range of processors from Intel, AMD, Arm, and others. But a newly discovered hardware security flaw impacts specifically the Atom, Celeron, and Pentium from the Apollo Lake, Gemini Lake, Denverton … low-power processors we often feature on CNX Software. Researchers have managed to activate test or debug logic at runtime for some low-power Intel processors, which they could use to escalate privilege, retrieve the “fuse encryption key” aka “chipset key fuse” unique to each processor, and access encrypted data. Most people do not need to panic though, as the hack would require physical access to the machine, and Intel says it is releasing firmware updates to mitigate the vulnerability. High-value targets should care though as the hack only takes 10 minutes, and if a laptop is stolen or lost, a skilled attacker should be able to […]
Experiences of configuring and using a ‘hackendeck’ homemade Steam Deck
Valve recently released information about developing for the Steam Deck if you didn’t have a Dev-Kit which is an engineering verification test build (EV2) version of their device. Included in the documentation is a suggestion to build your own Steam Deck, or ‘hackendeck’ using a mini PC. Whilst I didn’t have the exact brand they picture in the article I did have a mini PC with the required specifications so I set about following the instructions to see how it performed. Hardware Overview Valve’s documentation under ‘Performance’ states that ‘if you are really interested in finding a PC for testing that will perform similarly to a Steam Deck … there are a few options out there and then goes on to suggest a mini PC with the following ‘roughly similar specifications to a Steam Deck’: AMD Ryzen 7 3750H Radeon RX Vega 10 Graphics 16GB of DDR4 RAM This exactly […]
