Review of GEEKOM Mini Air12 Processor N100 mini PC – Part 1: unboxing and teardown

GEEKOM Mini Air12 is a mini PC powered by the popular Intel Processor N100 CPU and coupled with 16GB DDR5 SO-DIMM memory, a 512GB NVMe SSD upgradable up to 1TB. The Windows 11 Pro mini PC also features USB 3.2 Gen 2 USB Type-C ports, HDMI 2.0 video output, gigabit Ethernet, as well as WiFi 6 and Bluetooth 5.2 via an Azureware module. GEEKOM sent us a sample of the Mini Air12 for review. Since we’ve already written about the Mini Air12 specifications, today we will go through an unboxing and look at the hardware design with a teardown, before testing the mini PC in more detail with Windows 11 and Ubuntu 22.04 in the next parts of the review. GEEKOM Mini Air12 Unboxing We received the mini PC is a retail package that protects the device and accessories inside well. The back side of the package lists some basic […]

Genmitsu Z5-1 fiber laser engraver review

Good day. Karl here. Today I would like to share my experiences with the Genmitsu Z5-1 fiber laser engraver in this review. What is an infrared Galvo laser? A fiber laser is also known as an infrared Galvo laser. Let’s break this combination of words down. Infrared is first. Up to this point, I have reviewed several powerful blue diode lasers for the site. All of them have had 455nm wavelength lasers. In contrast, the Genmitsu Z5-1 laser we are looking at today has a 1064nm wavelength that is outside of the visible spectrum. With infrared, we can mark different materials. Notable plastics and metals are easy to mark with this laser. Galvo is next and was a term I was not familiar with. “Galvo” is a condensed form of “galvanometer.” It’s an electromechanical device used for precise mirror or optical element control in laser and optical systems. Galvanometers are […]

GEEKOM A5 Review – Part 3: An AMD Ryzen 7 5800H mini PC tested with Ubuntu 22.04

In the first part of GEEKOM A5 mini PC review, we had a look at the hardware with an unboxing and teardown, we then reviewed the AMD Ryzen 7 5800H mini PC with Windows 11 Pro in the second part, and we’ve now had time to test the GEEKOM A5 mini PC with Ubuntu 22.04 to check how well it can work in Linux, and we’ll report our experience in this article. Installing Ubuntu 22.04 on GEEKOM A5 We shrank the Windows 11 partition by half to install Ubuntu 22.04 in dual boot configuration alongside the operating system from Microsoft. Ubuntu 22.04.3 was installed successfully using a USB drive. and everything went relatively smoothly, except WiFi didn’t work reliably (more than that later). So we had to use Ethernet for most of the review, and we used the GL.iNet Spitz AX router (GL-X3000NR) configured in repeater mode using an Ethernet […]

M.2 10GbE network card sells for $86

Almost two years ago, we wrote it was possible to add 10GbE to your system with a M.2 network card based on a Marvell AQC113 chip for about $170. But I’ve now been made aware prices may have come down a lot as another M.2 10GbE network based on the Marvell AQC107 chipset is now selling for $86 including shipping (to Thailand). Just like the previous model, the M.2 card does not include an RJ45 port, instead, it’s included in a separate board that’s mountable to a standard PC plate and connected through a flat cable to the M.2 module. Specifications: Network controller – Marvell AQC107 PCIe Gen3 x4 10Gbps Ethernet controller supporting 10GBASE-T, 5GBASE-T, 2.5GBASE-T, 1000BASE-T, and 100BASE-T (but not 10BASE-T) Aquantias AQrate PHY up to 10GbE using Cat 6a cables, as well as 5 GbE and 2.5 GbE over 100 meters with Cat 5e cables Energy Efficient Ethernet […]

Tiny Raspberry Pi RP2040 module connects to USB-C + buttons board via FPC connector

Waveshare RP2040-Tiny is another tiny Raspberry Pi RP2040 module that joins others like Pimoroni Tiny 2040, DFRobot Beetle RP2020, or Solder Party RP2040 Stamp, but with a twist as the solderable module features an FPC connector in order to optionally connect a separate board with a USB-C port as well as Boot and Reset buttons. This design enables the convenience of having a USB-C port for power and programming, plus the Reset and Boot buttons during firmware development, and developers can only keep the tiny and ultrathin module when integrating it into a project or product. Alternatively, there may be designs that benefit from having the USB-C port located further away from the main module with all I/Os, and it can also facilitate troubleshooting when the product is already integrated into a product. Waveshare RP2040-Tiny specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133Mhz with 264kB […]

Review of SONOFF BASICR4 Smart Switch and S-MATE2 Smart Remote Control

We’ve received two new devices from SONOFF for testing, namely the BASICR4 Smart Switch and the S-MATE2 Smart Remote Control. For those familiar with SONOFF devices, the Basic series is well-known as it was one of the initial products SONOFF introduced to the Smart Home market. It’s a Wi-Fi switch that can be used for various purposes, including controlling lights, fans, and other electrical devices. The BASICR4 model enhances capabilities while reducing costs compared to its predecessor. The S-MATE2, on the other hand, is the second version of a simple Remote Controller powered by batteries. It wirelessly connects to other SONOFF devices that support the eWeLink Remote Gateway feature, enabling full control within the same ecosystem. This expands its usability across different devices. Let’s delve into the details. SONOFF BASICR4 Introduction The Basic series has been a long-standing Wi-Fi Switch family allowing control of electrical devices through the eWeLink app […]

AirGradient ONE Kit Review – An open-source indoor air quality monitor

The product we are reviewing today is the “AirGradient ONE” air quality monitor kit which is an updated version of the earlier AirGradient air quality monitor. The device is equipped with sensors from Sensirion and Plantower, allowing it to measure many air quality parameters such as CO2, PM2.5, TVOCs, NOx, temperature, and humidity. It is an indoor air quality monitor that is both open-source software and open hardware. This means that the Arduino source code, schematic diagrams, PCB, and 3D models of the enclosure are available to developers. AirGradient ONE DIY Kit Unboxing The device was packaged within a cardboard box, with a greeting card from the manufacturer. The card features a QR code linking to a webpage with the installation guide. Since I requested the Kit version (there’s also a fully assembled model), some sensors were not pre-assembled and they were well-packaged in separate seals. The main PCB was […]
