GL.iNet Beryl AX OpenWrt router review – WiFi 6 performance, repeater, NAS, and 4G hotspot modes

Power bank GL.iNet GL-MT3000 Beryl AX router

In the first part of the review of GL.iNet GL-MT3000 “Beryl AX” pocket-size WiFi 6 OpenWrt router we had a look at the specifications, the package content, and the hardware design with a teardown of the little router. I’ve now had more time to play with the router focusing the review on WiFi 6 performance, and some of its functions such as repeater, NAS, and 4G hotspot. The router also supports VPN client and server modes, the Tor network, and Adguard Home, but I’ll invite readers to check out the GL.iNet Brume 2 security gateway review since I went through all these, and the hardware is very similar minus wireless connectivity. Initial setup of the Beryl AX router If you connect an Ethernet cable to the router you can switch to step two. If you only rely on WiFi for the setup that works too as the Beryl AX router […]

TerraMaster F4-423 review – A low-power 4-bay NAS tested with Unraid

Terramaster F4-423 NAS review

Hey Karl here. The timing couldn’t have been more opportune when I was asked to review the TerraMaster F4-423 4-bay NAS. Let me explain why. I run Unraid as my OS of choice for my home lab. I have found it easy to maintain and hard to break. My old rig had a 3900X with 3 cores, 6 threads dedicated to docker containers, and the remaining cores running VM’s. It has been a fun and learning experience. I have run it with several different VM configurations over the past few years. The majority of the time I ran 2 VM’s. One personal and one work and I would RDP over to the work VM. If I wanted to game I had a third gaming VM and allocated all resources to it. It’s not super convenient and as convoluted as it sounds. But recently I moved back to my company-provided laptop […]

Raspberry Pi Camera Module 3 review – HDR, autofocus, wide angle, and NoIR camera

Raspberry Pi Camera Module 3 review

A few days before launching the Raspberry Pi Camera Module 3 with HDR and autofocus, Raspberry Pi Trading asked me whether I would be interested in reviewing the new modules, and sent me three samples: the standard module, the Raspberry Pi Camera Module 3 Wide, as well as the NoIR version that lacks an IR filter and is better suited for night shots. It took a full week for DHL to send the package to my house, but I’ve now had time to review the new Raspberry Pi Camera Module 3, mostly with libcamera, but also Picamera2, focusing on the new features such as HDR, autofocus, and wide angle. I also had a quick try at the Raspberry Pi Camera Module 3 NoIR but without IR lights. Regular readers know I had already made some DIY camera mounts using empty gum bottles, and I just replaced the Lotte XYLITOL stickers […]

TwoTrees TS2 laser engraver review – Part 2: A beginner’s experience with LaserGRBL and MKSLaser

TwoTrees TS2 laser engraver with MELE PCG02 PC stick

I’ve now had time to play with TwoTrees TS2 laser engraver after doing an unboxing and providing assembly instructions last month, so I can report my experience in this review using LaserGRBL program and MKSLaser mobile app. Note that this is my first laser engraver, and I’ll detail the many issues and mistakes I’ve come across so it might be useful to other beginners. Testing TS2 laser engraver assembly Before doing some engravings and cuts, we’ll have to test the TS2 to make sure it was properly assembled and we can operate it normally. The company is recommending the open-source and free LaserGRBL or the paid Lightburn program to control the TS2. I went with the former which happens to only work in Windows or macOS, while most of my hardware is running Linux or Android. So I dug out an older HDMI PC stick, the MeLE PCG01 running Windows […]

Review of Creality Ender-3 S1 Pro 2-in-1 3D printer & laser engraver – Part 1: Unboxing and assembly

Ender-3 S1 Pro 3D printer converted into a laser engraver

Creality Ender-3 S1 Pro is a 3D printer that can be converted into a laser engraver thanks to a choice of 1.6W, 5W, and 10W laser modules, making it in theory a space-saving machine that can print 3D objects and engrave & cut materials. The company sent me a full kit with a 10W laser module, so after looking at the 3D printer’s specifications, I’ll check the various packages, and report my experience assembling the 3D printer, and then converting it into a laser engraver in this article, before actually testing both functions in the second part of the review. Since Karl reviewed the Ender-3 Pro 3D printer over two years ago, I asked about the difference and was told the new model got various improvements such as a direct extruder, CR-Touch auto bed-leveling, and support for high-temperature printing. Creality Ender-3 S1 Pro specifications Technology – FDM Maximum printing volume […]

Khadas VIM1S (Amlogic S905Y4) SBC review with Android 11

Khadas VIM1S Android 11 review

We’ve previously tested Ubuntu 22.04 on Khadas VIM1S Amlogic S905Y4 SBC, so we’ll switch to Android 11 in the second part to check out the user experience and benchmark the system under Android. Installing Android 11 on Khadas VIM1S board with OOWOW We’ll basically follow the same procedure as with Ubuntu to flash the Android OS. Press and hold the Function button, press the Reset button, and release the Function button. to enter the OOWOW Wizard, and if an Ethernet cable is not connected, select Network to configure Wi-Fi as the installation process requires downloading an image from Khadas servers. This time, we’ll select the latest Android 11 image namely vim1s-android-11-v221020.raw.img.xz At just 525 MB in size (when compressed), the Android 11 image for Khadas VIM1S board is fairly compact. Installing Android with OOWOW is really easy with the interface downloading and flashing the image to the eMMC flash without […]

GL.iNet GL-MT3000 pocket-sized Wi-Fi 6 Router review – Part 1: Specs, unboxing, and teardown

GL-MT3000 portable WiFi 6 router

GL.iNet Beryl AX (GL-MT3000) is a pocket-sized Wi-Fi 6 router running OpenWrt on a MediaTek MT7981B (Filogic 820) dual-core processor @ 1.3 GHz and equipped with a 2.5GbE port, a Gigabit Ethernet port, and a USB 3.0 port. The hardware is basically the same as the Brume 2 (GL-MT2500A) security gateway, except it adds support for WiFi 6 connectivity and as an AX3000 router more than doubles the bandwidth compared to the earlier Beryl (GL-MT1300) AC1300 router. The company has sent me a sample so I’ll start the two-part review by checking the specifications, doing an unboxing, and tearing it down to have a closer look at the hardware design, before trying out OpenWrt and testing WiFi 6 and 2.5GbE performance in the second part of the review. GL.iNet GL-MT3000 specifications Beryl AX specifications: SoC – MediaTek MT7981B (Filogic 820) dual-core processor @ 1.3 GHz System Memory – 512MB DDR4 […]

Khadas VIM1S review – Ubuntu 22.04 tested on an Amlogic S905Y4 SBC

Khadas VIM1S review

In this review of Khadas VIM1S SBC, we’ll install Ubuntu 22.04, and report our experience testing the performance such as memory speed and eMMC flash performance, and 3D graphics capabilities. Installing Ubuntu 22.04 on Khadas VIM1S Just like Khadas VIM4 and Edge2, the Khadas VIM1S SBC ships with the OOWOW firmware that allows easy installation of operating systems by downloading the images, and flashing them directly to the eMMC flash.  You need just to connect a monitor and a USB keyboard and have an Internet connection through either LAN or Wi-Fi. Let’s start by installing Ubuntu 22.04 on Khadas VIM1S together. If no OS is installed, OOWOW will boot automatically, but if there’s already another OS installed, you can press and hold the Function button, press the Reset button, and release the Function button. After a few seconds, the OOWOW Wizard as shown in the picture below should show up. […]
