GEEKOM Mini IT11 (Core i7-11390H) review with Ubuntu 22.04 Linux (Part 3)

We’ve already reviewed GEEKOM Mini IT11 (Core i7-11390H) mini PC with Windows 11 Pro, so in the final part of the review, we’ve switched to Ubuntu 22.04 Linux operating system installed alongside Windows 11 on the Intel Core i7-11390H Tiger Lake mini PC. We’ll go through the software overview and test hardware features, run some benchmarks to evaluate the performance of the system, and report our findings with regard to power consumption and thermal performance. We’ve resized the partition in Windows 11 in the Disk Management program in order to install Ubuntu 22.04 from a USB flash drive on the Mini IT11 computer, and the installation went smoothly, and surprisingly fast according to the reviewer. Ubuntu 22.04 system information The About section in Ubuntu 22.04 Settings shows the Mini IT11 mini PC comes with an 11th Gen Intel Core i7-11390H CPU with eight threads clocked at 3.4 GHz and Intel […]

Review of SunFounder Raspberry Pi UPS Power Supply

SunFounder’s Raspberry Pi UPS Power Supply is a complete UPS kit for the Raspberry Pi 3/4 Model B/B+ with a PiPower board, a 2,000 mAh battery, and all accessories requires for the assembly. It also works with other Raspberry Pi-sized boards that support 5V DC input such as Banana Pi BPI-M5, Libre Computer ROC-RK3328-CC, and other similar SBCs. Many years ago, I bought a Raspberry Pi battery pack for review hoping that it would also work as a UPS, but it was not perfect as the board would sometime reboot during power failure simulations. Since then, there have been many UPS kits launched to the market, but I didn’t try any so far, so when SunFounder contacted CNX Software to review their “Raspberry Pi UPS Power Supply”, I took the opportunity, and I will report my finding in this review. Raspberry Pi UPS Power Supply key features UPS module output […]

LiFi 802.11bb standard uses light for in-room data transmission up to 224GB/s

The 802.11bb WiFi-like standard, also called LiFi, was ratified in June 2023. It enables data transmission up to 224GB/s at a few meters range within a room using light instead of RF signals used in most other wireless standards. The technology has been worked on for many years, and we first covered (a version of) LiFi in 2014 that was still part of the IEEE 802.15 standard with speeds up to 1 Gbps. But the Light Communications 802.11bb Task Group was only formed in 2018 chaired by pureLiFi and supported by Fraunhofer HHI, and led to be ratification of the IEEE 802.11bb standard last month. In a typical LiFi setup, you’d have a LiFi-capable router connected to your local network and the Internet, a LiFi-enabled light bulb on a ceiling, and one or more LiFi receivers. From the end-user perspective, it would work like accessing a WiFi access point. We’re […]

GEEKOM MINI IT11 Review – Part 2: Windows 11 Pro on an Intel Core i7-11390H mini PC

We’ve previously checked out GEEKOM Mini IT11’s hardware and accessories with some specs, an unboxing, a teardown, and a first boot of the Intel Core i7-11390H mini PC in the first part of the review. We’ve now had time to thoroughly test the Tiger Lake mini PC with Windows 11 Pro, and we’ll go through a software overview, benchmarks, power consumption, and more in the second part of the review. Software overview GEEKOM Mini IT11 (Core i7-11390H) mini PC ships with Windows 11 Pro version 21H2 OS build 22000.1219. We can further confirm the specifications with the HWiNFO64 program to show the system is based on an Intel Core i7-11390H with four cores and eight threads and  Intel Iris Xe Graphics and comes with 32GB dual-channel DDR4 memory, and a 1TB NVMe SSD. The Western Digital hard drive we added to the mini PC also shows up in the list […]

Affordable RTK GNSS receiver supports USB or/and Ethernet interfaces (Crowdfunding)

HYFIX’s RTK Rover is an affordable, centimeter-accurate RTK (Real-time Kinematic) GNSS receiver with either a USB interface or/and Ethernet connectivity with the latter relying on a Raspberry Pi 4 SBC. As a reminder, RTK relies on traditional GNSS networks like GPS and works with a Base station at a fixed location and a Rover station that can be fitted to a drone or mobile robot in order to determine the position with up to one-centimeter accuracy. The RTK Rover from HYFIX is equipped with a dual-band LC29H GNSS module from Quectel and an onboard IMU sensor that tracks position through dead reckoning when GNSS connectivity is lost. RTK Rover specifications: MiniPCIe card with Dual-Band L1/L5 RTK Receiver (Quectel LC29H) Antenna – External antenna (6x5x2 cm) connected to SMA connector Sensor – IMU Interfaces USB Type-C port for power and serial Interface Ethernet Rover Kit only – Gigabit Ethernet and  USB ports […]

CZUR ET24 Pro book scanner review – Part 1: Specs, unboxing, and first try

CZUR ET24 Pro is a professional book scanner with 320DPI optional resolution (delivering up to 24MP images) that works with Windows, macOS, and Linux via a USB port, or even in standalone mode through an HDMI port that could be used for business presentations. When CZUR contacted me about reviewing a scanner, I was not sure it would be interesting, but then I was intrigued because it looks like a bedside light and I had never used this type of scanner.  So I decided to give a go, and here I am with a review sample. It looks like it should be especially useful for people scanning a lot of documents or books as it’s designed for speed and should significantly improve productivity over a traditional scanner with a cover, while hopefully keeping the quality. But we’ll check that in the full review. CZUR ET24 Pro specifications Optical resolution – […]
