ArmWizard forum member “-W.-” needed a cluster to test his firmware build and deployment solution for Orange Pi Zero boards which can deploy the firmware to multiple boards from one single board. So he procured 24 Orange Pi Zero boards, a 24-port switch, some USB hubs and debug board, as well as some other accessories, power supplies, and two wooden planks. That’s the results after assembly. So we have 4 tower of six Orange Pi Zero boards fairly neatly connected to the 24-port Ethernet switch with 30 cm Ethernet cables, and four black USB hubs for the USB to TTL debug boards. The side view below shows the boards are powered by micro USB cables connected to three different power supplies, cooling achieved via four fans, and the power extension is hidden right underneath close to the Ethernet switch. The cluster will also be used for machine learning latter on, […]
Run Linux Apps in (PixelBook) Chromebook with Crostini VM
Ever since the first Chromebooks were released, it has been possible to run Ubuntu or other Linux distributions using Crouton (Chromium OS Universal Chroot Environment) on Chrome OS devices, but that requires to enable developer mode, which disables some of security features that come with Chrome OS. Google has now make it easier and safer with Crostini VM that does not require developer mode. The only downsides for now are that it only works on Google Pixelbook, and you need to install/run Chrome OS v67 dev channel with the #enable-cros-container flag enabled. Using Crostini is fairly straightforward. First start crosh terminal with Ctrl++Atl+t, and running the following command to create a VM, and launch a container:
1 2 |
vmc start dev run_container.sh --container_name=stretch --user=<username> --shell |
This will start a Debian Stretch environment with networking and GUI support, so you can install & run programs like you would in Debian (e.g. apt install htop). Kevin Tofel at AboutChromebooks managed […]

SudoProc is a Tiny LGA System-on-Module Based on Rockchip RK3288 SoC
Most systems-on-module are designed to be inserted into a baseboard thanks to an edge connectors or one or more board-to-board connectors, although I’ve also seen some with castellated pins allowing them to be soldered to the carrier board. The guys at Sudo Systems LLC have taken a different approach as they went with a custom designed 210-pin LGA (Land grid array) module instead, which is based on Rockchip RK3288 processor, and extremely compact at 65 x 40 x 4.3 mm. SudoProc module specifications: SoC – Rockchip RK3288 quad core Cortex-A17 processor @ up to 1.8 GHz with Arm Mali-T764 GPU System Memory – 4GB LPDDR3 (Samsung) @ 1066MHz; 2 x 32 bit, dual channel Video Decoding – H.264 decoder @ 2160p@24fps, H.265 decoder @2160p@30fps, and H.264/MVC/VP8 encoder 1080p@30fps Storage – 32GB, 64GB, 128GB, 256GB or 512GB eMMC 4.5 flash LGA package with 210 pins exposing: Storage I/F – 8-bit NAND […]

FOSSASIA Summit 2018 Schedule – March 22-25
FOSDEM is the “Free & Open Source Software Developers’ European Meeting” takes place the first week-end of February every year in Brussels, Belgium. It turns out there’s an event in Asia called FOSSASIA Summit that’s about to take place in Singapore on March 22-25. There are some differences however, as while FOSDEM is entirely free to attend, FOSSASIA requires to pay an entry fee to attend talks, although there are free tickets to access the exhibition hall and career fair. There are also less sessions as in FOSDEM, but still twelve different tracks with: Artificial Intelligence Blockchain Cloud, Container, DevOps Cybersecurity Database Kernel & Platform Open Data, Internet Society, Community Open Design, IoT, Hardware, Imaging Open Event Solutions Open Source in Business Science Tech Web and Mobile Since the event is spread out over four days, it should be easier to attend the specific sessions you are interested in.
