Arylic BK501/651 bookshelf speakers integrate high-end AMT tweeters (Sponsored)

Arylic is better known for its connected audio devices such as the Arylic A50+ wireless amplifier or S50 Pro+ wireless stereo pre-amplifier, but the company has now launched its first passive speakers with the Arylic BK501 and BK651 bookshelf speakers that integrate high-end Heil AMT (Air Motion Transformer) tweeters. The BK501 is a pair of 5-inch speakers with 80W peak power, while the BK651 is a pair of 6.5-inch stereo speakers delivering up to 100W peak power. The specifications table below shows how both models compare. Both speakers support Treble up to 40kHz to feel detailed treble clarity and brightness, 180° wide soundstage, feature a fiberglass mid-woofer and received FSC Environmental Certification. Both designs include an MDF (medium-density fiberboard) cabinet with 15mm thick walls for the KB501 and 18mm thick walls for the BK651. Arylic says the Heil AMT tweeter found in its speakers uses a folded Kapton ribbon diaphragm […]

Convert your 3D printer into a metal cutting machine with an Electrical Discharge Machining kit (Crowdfunding)

Rack Robotics’ Powercore is an Electrical Discharge Machining (EDM) kit that converts your existing 3D printer (or CNC router) into a machine capable of cutting high-precision and detailed metal parts. We’ve already seen 2-in-1 3D printers and laser engravers such as the Creality Ender 3 S1 Pro, but while this type of machine can usually cut plywood or engrave stainless steel, the laser is not powerful enough to cut through aluminum. The Powercore EDM kit changes that by enabling the cutting of aluminum parts up to 4mm thick, although aluminum sheets that are 1mm or thinner are recommended. But before we get into Powercore details, what is Electrical Discharge Machining exactly? Engineers Edge explains: Electrical Discharge Machining, EDM is one of the most accurate manufacturing processes available for creating complex or simple shapes and geometries within parts and assemblies. EDM works by eroding material in the path of electrical discharges […]

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

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 […]

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

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 […]
