Karl here. This was article originally going to be how to setup Octoprint 3D printer server on an Orange Pi Lite. But after looking and running through the instructions it seemed like it would be too much so I created an img to simplify things. I also explored running Octoprint on an Amlogic S905x or S912 device and it turned out to be an even better solution. You get a case, power supply, and eMMC flash storage. What is Octoprint? I use Octoprint mainly for its ability to start and stop prints without having to use an sd card. Time lapse is also a nice feature. And one last thing is that I setup a pushbullet notification when it is complete. For a full list of features check out http://octoprint.org/. What is needed? Orange Pi Lite board provided by GearBest for the article, or an Amlogic S905X or S912 Android […]
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 […]
Orange Pi i96 96Boards IoT Edition WiFi & Bluetooth Development Board Finally Launched for $8.80
Orange Pi i96 board was first unveiled at Linaro Connect US 2016 in September of that year, as one of the first boards compliant with 96Boards IoT Edition specification, and expected to sell for just $9.99. The good news is that the board is now finally available for $8.80 plus shipping on Aliexpress ($12.19 in total in my case) Orange Pi i96 specifications: SoC – RDA Micro 8810PL ARM Cortex A5 processor @ up to 1.0 GHz with 2Gbit (256 MB) on-chip LPDDR2 RAM, 4Gbit (512 MB) on-chip SLC NAND flash , 256KB L2 cache, and Vivante GC860 3D GPU External Storage – micro SD slot Connectivity – WiFi 802.11 b/g/n + Bluetooth 2.1/EDR module (RDA5991) Camera – MIPI CSI-2 connector for camera sensor up to 5MP Video – 1080p30 H.264 encoding USB – 1x USB host port, 1x micro USB OTG port Expansion – 40-pin GPIO header with SPI, […]
H3Droid Android Firmware is Designed for Allwinner H3 Boards & Devices
Allwinner H3 boards such as Orange Pi PC and NanoPi NEO are mostly interesting due to their ability to run Linux and control I/Os, and while they also support Android, most people wanting to run Android are better served with TV boxes instead, as they come with enclosure, power supply, HDMI cable, and an IR remote control. That does not mean there’s no use case for Android on development boards, and that’s why probably KotCzarny, and other developers, have decided to work on H3Droid project to provide better Android images for Allwinner H3 boards and devices than the firmware released by manufacturers. Some of the improvements include “sane DRAM/CPU settings”, support for Custom recovery system, Google Play Store and more USB network adapters, as well as the removal of apps and feature unusable for people outside out China. You’ll also be able to access the board via SSH if you […]
Raiscube R2 (Prusa I3 Clone) 3D Printer Review – Part 2: 3D Print Samples, E3D Clone Installation, Tips & Tricks
Karl here with part 2 Exploring Raiscube R2. That is the official name by Raiscube. Gonna look at some more prints. Some mistakes I made in first part and some simple mods. Maybe not so much mistakes but an oversight. Oversight / Mistake So in the first part of Raiscube Prusa i3 review, I mentioned there were not very good instructions, and they sent a blank SD card with the kit. I was wrong. On first inspection, it looked like a factory sealed SD card but it is not. It is an 8 GB card with videos, instructions, pictures, parts list, STL, and gcode files as well as an old version of Cura. Not blank at all with about 1.5 GB of files. It didn’t include settings but if you install the latest Cura, it just takes a little tweaking to print well. Official specs from SD card Brand RAISCUBE […]
$10 Smartphone Display Released for Orange Pi 2G-IoT Board
Orange Pi 2G-IoT is a low cost ARM Linux board with 2G, and WiFi & Bluetooth connectivity, basically with the guts of a smartphone minus the display and battery. Shenzhen Xunlong has now released a 800×480 display with capacitive touch support for the board available in black or white, and selling for $9.98 plus shipping. The board is too thick to make a smartphone out of it, but it reminds of the very expensive Qualcomm MDP’s (Mobile Development Platform), so Android app developers may find some use to test their apps on lower end hardware. It could also be used for control panels that do not need to be very thin. Orange Pi 2G-IoT display specifications: 3.5″ TFT Display with 800×480 resolution Capacitive touchscreen Case with the Back, Home, and Recent buttons Dimensions – With case: 57.14 x 96.85 x 2.0 mm; Display only: 51.84 x 86.4mm Software support is […]
Linux 4.11 Release – Main Changes, ARM & MIPS Architecture
Linus Torvalds has just released Linux 4.11: So after that extra week with an rc8, things were pretty calm, and I’m much happier releasing a final 4.11 now. We still had various smaller fixes the last week, but nothing that made me go “hmm..”. Shortlog appended for people who want to peruse the details, but it’s a mix all over, with about half being drivers (networking dominates, but some sound fixlets too), with the rest being some arch updates, generic networking, and filesystem (nfs[d]) fixes. But it’s all really small, which is what I like to see the last week of the release cycle. And with this, the merge window is obviously open. I already have two pull request for 4.12 in my inbox, I expect that overnight I’ll get a lot more. Linux 4.10 added Virtual GPU support, perf c2c’ tool, improved writeback management, a faster initial WiFi connection […]
RDA Micro RDA8810 Android SDK with Linux & U-boot Source Code for Orange Pi 2G IoT Board Released
Orange Pi 2G IoT board was released a couple of weeks ago, shortly followed by Android and Ubuntu images, but since it was not based on Allwinner, but an RDA Micro 8810PL processor, we did not have any source code so far, which can be a real problem for a development board… Shenzhen Xunlong has now managed to upload a 6.7GB Android SDK to MEGA, with the link published via Orange Pi Resources page. MEGA has a download limit which depends on how much traffic they get at the time, and after 5.3 GB download, I was asked to register for a PRO account, or wait for four hours before resuming the download. If you want to avoid this limit for any large MEGA download, you can run megadl instead. That’s what I did in Ubuntu 16.04 (remember to escape any special characters with \):

sudo apt install megatools megadl https://mega.nz/#F\!59EVmKAZ\!5FdBb2dQIMcxgY2h16nGPg |
