GNUBee Personal Cloud 2 is a DIY NAS Supporting up to Six 3.5″ SATA Drives (Crowdfunding)

GNUBee Personal Cloud 1 is a DIY NAS powered by Mediatek MT7621A MIPS processor that supports up to 2.5″ SATA drives, and runs free and open source software. It was first introduced in March of this year through a CrowdSupply campaign. The developers are now back with GNUBee Personal Cloud 2 (GB-PC2) with pretty much the same features, but instead of being designed for 2.5″ drives, it supports up to six 3.5″ drive that should offer either more capacity, or a lower total price for an equivalent capacity. GB-PC2 NAS specifications: Processor – MediaTek MT7621A dual core, quad thread MIPS processor @ 880 MHz, overclockable to 1.2 GHz System Memory – 512 MB DDR3 (max supported by MT7621) Storage – SD card slot tested up to 64 GB, 6x 3.5” SATA HDD or SSD (recommended RAID 0 or 1 under LVM, MD, or Linux MD RAID 10) Connectivity – 3x […]

Review of Vobot Alarm Clock with Alexa

Karl here with a review of Vobot sent By Cafago. I had to Google it when I was asked to review it. Turned out it was an Echo type device with a pixel display and a battery. It started as an Indiegogo campaign. I had been wanting to try to do some sort of voice control with my home automation so I agreed to review it. Vobot Clock C1 Specifications These are pulled from Vobot’s website. No power supply is included but a long USB cable is. Vobot Setup I let my wife do the initial setup as I figured that she would use it the most. She followed the instructions, and it seemed straightforward from what she told me. She said she had to reboot it once during a step but it continued the setup with no problems. She tied to our Amazon Prime account, and she quickly was […]

Linux 4.13 Release – Main Changes, ARM & MIPS Architectures

Linus Torvalds has just announced the release of Linux 4.13 and a kidney stone…: So last week was actually somewhat eventful, but not enough to push me to delay 4.13. Most of the changes since rc7 are actually networking fixes, the bulk of them to various drivers. With apologies to the authors of said patches, they don’t look all that interesting (which is definitely exactly what you want just before a release). Details in the appended shortlog. Note that the shortlog below is obviously only since rc7 – the _full_4.13 log is much too big to post and nobody sane would read it. So if you’re interested in all the rest of it, get the git tree and limit the logs to the files you are interested in if you crave details. No, the excitement was largely in the mmu notification layer, where we had a fairly last-minute regression and […]

A Look at Some USB 3.0 WiFi 802.11ac Adapters with Multiple High Gain Antennas

When last week I reviewed Rock64 board I noticed they sold a “USB 3.0 Dual Band 1200Mbps WIFI 802.11 a/b/g/n/ac (RTL8812AU) adapter” for $19.99. So far I had only seen USB dongles with internal antennas or a single external antenna, but in the case of development boards, which may be used as routers or gateways, it makes perfect sense to get such adapter for higher performance and longer range. The only problem is that it “ships together with ROCK64 fulfillment”, meaning you can’t purchase it separately if you already have some other board to use, so I went to look for alternatives. One of the first I’ve come across was COMFAST CF-926AC with the following specifications: Chipset – Mediatek MT7612U Interface –  USB 3.0 rotatable port WiFi – Dual band 2T2R WiFi 802.11ac, 802.11a, 802.11b, 802.11g, 802.11n up to “1200” Mbps (867 Mbps @ 5.8 GHz + 300 Mbps @ 2.4 […]

Onion Omega2S and Omega2S+ Linux WiFi Modules Launched for OEMs

Onion Omega2 and Omega2+ are tiny WiFi IoT development boards powered by Mediatek MT7688 MIPS processor running LEDE – OpenWrt fork – that sold for just $5 and up in Kickstarter, but are now selling for $7.50 and $9 respectively. The board also support various add-on boards, and a great for evaluation and various projects. But they may not be ideal for people who want to integrate the technology into their products, and that’s why the company have just launched Omega2S and Omega2S+ with about the same specifications, but in a package more suitable to be integrated into products for mass production. Onion Omega2S/2S+ specifications: WiSoC – Mediatek MT7688 MIPS processor @ 580 MHz System Memory / Storage Omega2S – 64MB DDR2 / 16MB flash Omega2S+ – 128MB DDR2 / 32 MB flash Connectivity – 802.11 b/g/n WiFi with u.FL antenna connector Baseboard Interface – Half holes (aka castellated holes) […]

Linux 4.12 Release – Main Changes, ARM & MIPS Architectures

Linus Torvalds has just released Linux 4.12: Things were quite calm this week, so I really didn’t have any real reason to delay the 4.12 release. As mentioned over the various rc announcements, 4.12 is one of the bigger releases historically, and I think only 4.9 ends up having had more commits. And 4.9 was big at least partly because Greg announced it was an LTS kernel. But 4.12 is just plain big. There’s also nothing particularly odd going on in the tree – it’s all just normal development, just more of it that usual. The shortlog below is obviously just the minor changes since rc7 – the whole 4.12 shortlog is much too large to post. In the diff department, 4.12 is also very big, although the reason there isn’t just that there’s a lot of development, we have the added bulk of a lot of new  header files […]

Banana Pi BPI-R2’s U-boot & Linux 4.4 Source Code & MediaTek MT7623N Datasheet Released

Banana Pi BPI-R2 is a multimedia router board powered by MediaTek MT7623N quad core processor with 2GB RAM, 5 Gigabit Ethernet ports, up to two SATA ports, two USB 3.0 ports, HDMI output, and I/O headers. The board is not for sale yet, but the company has recently released the source code with U-boot and Linux 4.4.70, as well as a datasheet for MediaTek MT7623N processor. The source code can be found on Github, so let’s see if we can build it:

After a couple of minutes, the build would end with:

For the very last step, it asks you to login as root / sudoer, which it should not do… But we end up with the images, so at least it builds:

MediaTek has also been active by committing patchsets for MT7623 to the Linux Kernel Mailing List, so mainline Linux is an eventual possibility for […]
