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

Arylic Bookshelf Speakers

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 […]

iKOOLCORE R1 review – A quad 2.5GbE mini PC tested with Windows 11, Ubuntu 22.04, Proxmox

iKOOLCORE R1 review

When I first saw the iKOOLCORE R1 I was fascinated that a mini PC of similar size to the smallest fully functional ones available (think Chuwi LarkBox, GMK NucBox or ECS LIVA Q Series) could be equipped with four 2.5 gigabit Ethernet (2.5GbE) ports. I approached iKOOLCORE who kindly provided an R1 for review and I’ve looked at performance running both Windows 11 and Ubuntu 22.04 and dabbled with using hypervisors on this mini PC through Proxmox virtual environment. iKOOLCORE R1 specifications iKOOLCORE list the R1 specifications on their website as: Of note are the ‘EC, FCC, RoHS’ certifications indicating both European conformity and approval for use in the US. Technically ‘EC’ refers to an ‘EC declaration of conformity’ which is not a certificate, however, the ‘EC declaration of conformity’ is called a ‘CE statement’ or ‘CE certificate’ which is why you often see this abbreviated as ‘CE’. The rest […]

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

Powercore EDM 3D printer kit

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 […]
