Khadas Tone High Resolution Audio Board is Designed for Khadas VIM/VIM2, PCs, and Other SBCs

Khadas VIM and Khadas VIM2 are development boards powered respectively by Amlogic S905x and S912 processors that come with decent software support. The company also provides application specific add-on boards for their SBCs, and a while ago, I reviewed VIM2 with their dual tuner board and showed how to stream videos from my satellite dish or terrestrial antenna to the local network. Their latest solution is Khadas Tone board for high-quality audio applications.

Xiaomi Mi Router 4 is a $60 AC1200 Router with Three Gigabit Ethernet Ports

Xiaomi Mi Router 3 AC1200 router based on Mediatek MT7620A processor was launched in 2016 for just under $40 on online retailers. It had at least one caveat however, since it only supported Fast Ethernet. The company has now launched an upgraded version – Xiaomi Mi Router 4 -, still an AC1200 router, but equipped with a faster Mediatek MT7621A processor, and three Gigabit Ethernet ports. The new router sells for 199 RMB ($31 US) in China, but it’s also found for under $60 including international shipping on sites like Banggood or GearBest.

A Closer Look at Mediatek MT8516 Cortex A35 SoM / Devkit for Android Things

Mediatek-MT8516-SoM

Earlier this month, Google released Android Things 1.0, the first stable release for the IoT operating system, and announced several certified SoMs (systems-on-module) based on NXP i.MX 8M, Qualcomm SDA212 & SDA624, and MediaTek MT8516 SoCs. However at the time, beside some information about the processor itself, there was not many details about MT8516 system-on-module. Since then, MediaTek wrote a blog post about their Cortex A35 solution for Android Things & Google Assistant, so let’s have a look. First the MT8516 SoM is not exactly what I had expected, but instead a complete single board computer, and this is why they call it virtual SoM (vSOM). Google defines the latter as reference design provided by the chip vendors and certified by Google. Mediatek MT8516 quad core Cortex A35 vSoM / development board specifications: SoC – MediaTek MT8516 quad core Cortex A35 processor without GPU System Memory – 4Gbit (512MB) DDR3L Storage – 4GB eMMC flash Connectivity – 802.11ac 2×2 MIMO …

RAK833 is an Industrial Grade mini PCIe LoRaWAN Gateway Card

Mini-PCIe-LoRaWAN-Gateway

The most obvious way to setup your own LoRAWAN network is to get an off-the-shelf Gateway such as MatchBox, which can be easily installed, and configured using the built-in web interface. But if you need something more flexible, Rakwireless RAK833 could be an interesting option, as an industrial grade LoRaWAN gateway that you can just insert into an advanced router or computer’s mini PCIe slot.

Pi-Hole Kit is a Raspberry Pi based Ad Blocker

If you don’t like getting tracked or see ads, it’s normally easy enough to install an ad blocker plugin in your web browser. But if you want to save some resources on your computer(s) and/or prevent online ads on other devices – including TVs – on your local network, it’s possible to do so via an external device / router using software such as Pi-Hole that can be installed on a Raspberry Pi board (or other Linux machines) in order to filter ads before they even get to your computer. This would normally require you to get your own hardware, enclosure, flash the firmware on a board, and install Pi-Hole yourself. That should easy enough for most regular readers of this blog, but there’s no an option for less tech-savvy user, as Pi Supply and Pi-Hole have partnered to launch the Pi Hole Kit with everything in one packages and already setup. The kit contains the Pi Hole box, a …
