Getting Started with GL-S200 Thread Border Router kit

Getting Started GL-S200 Thread Border Router

Last week we checked out the hardware for the GL.iNet GL-S200 Thread Border Router kit with three nRF52840 Thread Dev Boards, and I’ve now had time to work with the kit, so I’ll report my getting started experience in the second part of the review. GL-S200 Initial Set Up I connected the WAN port to my Ethernet Switch itself connected to my modem router and the LAN port to my laptop, so I could access the web interface using the default IP address (192.168.8.1). The GL-S200 uses the same Admin Panel as other GL.iNet routers such as the Beryl AX router we reviewed at the beginning of the year. You’ll be greeted by a wizard to let you select the language and set a new password for the Admin Panel, and once you’re done you’ll have access to the familiar GL.iNet Admin Panel 4.x.x. After completing the wizard, the system […]

Pironman review – A Raspberry Pi 4 enclosure with M.2 SATA, safe power off, RGB LED strip, and more

Pironman review

SunFounder Pironman is a Raspberry Pi 4 enclosure inspired by Michael Klement’s DIY Raspberry Pi 4 mini server with an OLED display and ICE Tower cooling solution, as well as some improvements such as an aluminum alloy and acrylic enclosure, support for an M.2 SATA SSD, a power button for safe shutdown,  an IR receiver, and an RGB LED strip. The company sent me a Pironman kit without Raspberry Pi 4 for review. I’ll check the package content, go through the assembly, software installation, and testing of the unique features listed above. Pironman unboxing Some of the main specifications are listed on the side of the package. The enclosure comes fully disassembled with the Pironman board, metal and acrylic panels, RGB LED strip, OLED display, heatsink, fan, adapters, flat cables, screws, standoffs, and so on. The top of the Pironman board (JMS580-V1.8) comes with a JMicron JMS580 USB 3.2 Gen […]

xTool D1 Pro 20W Review – Mandala Art with a 20W laser engraver and cutter

xTool D1 Pro 20W Review Mandala Art

Hey Karl here. I am going to be sharing my experience with the xTool D1 Pro 20W. It is a 20W laser cutter/engraver with a 340x390mm working area. It has been heavily reviewed and I will comment on a few points I have not seen spoken about. I join a lot of Facebook groups for these reviews to get real-world feedback and ideas to write about. With nearly all forms of digital fabrication, I regularly read about misconceptions and frustration that stem from unknowingly purchasing a machine that requires a substantial amount of time and patience to learn. For this review, I kept a daily log and will summarize the time it took me to complete one project. I did get sidetracked on a few aspects and will take that time out. I am excited to share the results of the laser power testing I have been doing. Logs will […]

A first look at GL.iNet GL-S200 Thread Border Router kit with three nRF52840 Thread boards

GL-S200 Thread Border Router review with Thread Dev Boards

GL.iNet are better known for their routers, but the company is also offering IoT gateways and Smart Home hubs such as the GL-S10 BLE to MQTT IoT gateway. The company is now preparing to launch the GL.iNet GL-S200 Thread Border Router in early April, and I’ve been asked to do some beta testing before launch, so GL.iNet have sent me a kit with the GL-S200 and three Thread development boards acting as IoT nodes. A Thread Border Router acts as a WiFi or/and Ethernet gateway connecting to battery-powered Thread sensor nodes equipped with a low-power 802.15.4 radio. In this first post, I’ll go through the hardware and specifications, before reporting my finding in a separate post next week. GL-200 Thread Border Router kit unboxing and specifications The development boards are all identical and they were each kept in an antistatic bag. But let’s open the GL-S200 package first. The Thread […]

Weibu N10 Core i3-N305 mini PC review with Windows 11 and Ubuntu 22.04

Weibu N10 Alder Lake mini PC review

I’ve previously reviewed Weibu’s N10 mini PC, however, they have now extended the range of CPUs available to the N10 through the addition of Alder Lake-N processors. As a reminder, Weibu is a B2B company that offers total solutions and OEM/ODM services and they don’t sell directly to end users as their target clients are computer manufacturers like Acer and Hisense. Weibu have sent a pre-production sample of their latest N10 based on a Core i3-N305 Alder Lake N-Series processor to showcase its capabilities in this review. I will revisit the specification of the N10 and briefly look at the performance running both Windows 11 Pro and Ubuntu 22.04. Weibu N10 product specifications Weibu list the N10 specifications on their website as: However this probably needs qualifying as ‘Memory Capacity’ states ‘2*SO-DIMM’ which is correct for many processors, but Intel’s Core i3-N305 processor in the mini PC sample I received […]

SONOFF MINIR4 review – A Tiny WiFi Smart Switch tested with eWelink app/web, and R5 controller

SONOFF MINIR4 wiring

In this post, we’ll review the SONOFF Mini Extreme, also known as MINIR4, WiFi smart switch based on ESP32 wireless MCU by installing it into a wall-mounted light switch box and controlling it with both the eWelink mobile app for Android and the SONOFF R5 scene controller. SONOFF MINIR4 Installation We’ve already gone through the specifications, unboxing, and teardown in the announcement, so I’ll get straight to the installation part. Note this review was done with a light switch “box” (about 11x6cm) in Thailand, so your mileage may vary. The first challenge is that contrary to the similarly-sized SONOFF ZBMINI Extreme Zigbee switch, the MINIR4 WiFi switch requires a neutral cable, and most lights in Thailand are wired without a neutral wire, so I had to get the neutral wire from the outlet switch box underneath. When I call those “boxes” there are really holes in the wall here… Wiring […]
