Intel NUC Kit NUC7PJYH Review – An Intel Gemini Lake Pentium Silver J5005 Barebone Mini PC

When Intel released their latest NUC Gemini Lake mini PCs they prioritized cost over performance. As a result the processor they chose for the ‘Intel NUC 7 Essential’ mini PC is somewhat underwhelming. Fortunately they released another model in the series, the rather misleadingly named ‘Intel NUC Kit NUC7PJYH’ which is is actually a ‘barebones’ mini PC just needing a stick or two of RAM and an SSD for storage. It contains an Intel Pentium Silver Processor J5005 SOC which is a quad core processor bursting up to 2.80 GHz together with a slightly more powerful Intel UHD Graphics 605 processor that is capable of 4K support at 60Hz. Visually it is no different to the Celeron NUC reviewed earlier in that it is physically small consisting of an approximately 4.5″ square case about 2″ tall with a distinctive front panel that includes the power button and a couple of […]

AsteroidOS 1.0 Released – An Open Source Linux OS for Wear OS Smartwatches

We first discovered AsteroidOS, a Linux based open source operating system working on some Android Wear (now Wear OS by Google) smartwatches, in early 2016 while looking at FOSDEM 2016 schedule. The project and community have since grown to support more watches, and a company even tried to launch an AsteroidOS smartwatch (sadly unsuccessfully), but development kept going, and now the very first stable release is out with AsteroidOS 1.0. Some of the highlights of the release: AsteroidOS 1.0 features and apps: phone notifications, an agenda, an alarm clock, a calculator, a music remote control, settings customizations, a stopwatch, a timer, and a weather forecast app. Bluetooth Low Energy (BLE) sync with Android phones using AsteroidOSSync app. Supported hardware LG G Watch, LG G Watch Urbane, LG G Watch R Asus Zenwatch 1, Asus Zenwatch 2, Asus Zenwatch 3 Sony Smartwatch 3 Software emulator for testing and development. Community supported […]

Wi-Fi EasyMesh is a Standard for WiFi Mesh Networking

It’s been possible for add multiple WiFi routers and/or WiFi repeaters in order to provide good coverage in a house / building for years, so this required some manual configuration. So in recent years, companies came up with WiFi mesh networking solutions that do very much the same, but are easier to setup, and – as I understand it – mostly plug-and-play. Some examples are Google WiFi router or eeRo Pro WiFi system, but apparently so far every company would do their own proprietary WiFi mesh implementation, so you would not be able to mix brands for such features. That’s why the WiFi Alliance worked on, and now announced Wi-Fi EasyMesh, an industry standard for “simple to use, self-organizing, smart Wi-Fi networks”. Key benefits listed by the organization: Flexible design – Allows for best placement of multiple APs providing extended coverage Easy setup – Delivers automatic device on-boarding and configuration […]
