How-to Setup a DLNA/UPnP Server in Linux for Smoother Video Streaming with Kodi and Other Media Players

I’m normally playing videos from a SAMBA share installed in a Ubuntu PC to play files from Kodi in Android TV box reviews, but sometimes when I use 10/100 Ethernet, or worse WiFi local “streaming” may not be as smooth as possible. SAMBA is convenient because of access control and read write operations, but if you want to get a bit more performance, you may switch to NFS instead, or like I’ve going to show you here to a DLNA / UPnP server to stream videos locally from Kodi 16.1. There are several options, but MiniDLNA is lightweight compared to MediaTomb, so it will also run on lower end hardware like cheap ARM Linux development boards like Raspberry Pi, Orange Pi, or NanoPi NEO without taking too many resources. Installation is very easy in Debian / Ubuntu distributions, and I supposed this should also work with Windows Subsystem for Linux […]

Project OWL Open Source Hardware Ophthalmoscope is 25 Times Cheaper than Commercial Products

Medical grade equipments are usually very expensive, partly because of their complexity, but also because of certifications,   legal reasons, and low manufacturing volumes. That’s where open source hardware can make a big difference, and there has been several open source hardware prosthetic hands or arms such as Openbionics hand, but Ebin Philip and his team has tackled another issue with Project OWL, an open indirect ophthalmoscope (OIO) designed for screening retinal diseases, which normally costs between $10,000 to $25,000, but their open source hardware design can be put together for about $400. The design features a Raspberry Pi 2 board connected to a WaveShare 5″ Touchscreen LCD, a Raspberry Pi Pi IR Camera (M12 lens mount) with 16mm FL M12 lens, a 3 Watt Luxeon LED, two 50x50mm mirrors, a linear polarizer sheet, a 20 Dioptre disposable lens, and various passive components. While the Raspberry Pi board is not open […]

U-Boot Now Supports UEFI on 32-bit and 64-bit ARM Platforms

Intel/AMD x86 based computers now boot via a standard UEFI binary, which can load grub2, allows you to update the command line as needed, or select different version of the Linux kernel. On ARM everything is a little more complicated and messy, as bootloaders such as U-boot need to support different configurations formats. Alexander Graf has been working on implementing UEFI support in U-boot, and it’s now supported by U-boot mainline and enabled by default for 32-bit and 64-bit ARM platforms, but not x86-64 (yet). That means you should now be able to boot any ARM boards supported by mainline U-boot through UEFI. Alexander gave a presentation about his work at an openSUSE event in June, and demonstrated u-boot with UEFI, and GRUB2 support with an openSUSE image running on a Raspberry Pi board. Thanks to David for the tip.

Minimal Ubuntu 16.04 Image for ODROID-C2, and C1/C1+ Boards, Ubuntu Core Image for Bubblegum-96 Board

If you’ve been wanting minimal Ubuntu distributions for your server, IoT, or other headless projects, there are some good news from Hardkernel with the release of a minimal Ubuntu 16.04 image for ODROID-C2 and ODROID-C1+ boards, and Canonical has recently announced Actions Semi S900 based BubbleGum-96 board was getting support for Ubuntu Core distribution. If you’re using an ODROID board you can download ubuntu64-16.04-minimal-odroid-c2-20160803.img.xz (196MB) firmware, which become 1.7 GB once uncompressed and flash it 2GB or greater micro SD card. After Raspberry Pi 2 and Samsung Artik 5/10, Bubblegum-96 is the third officially supported board that can run Ubuntu Core. You can download the 3.63GB beta image and instructions to flash it from an Ubuntu 16.04 machine on Mega. Bugglegum-96 is a 96boards compliant development board based on an quad core Cortex A53 processor with 2GB RAM and 8GB flash manufactured and sold by ucRobotics for $89.

Samsung JerryScript is a Lightweight Open Source JavaScript Engine for the Internet of Things

In the old days, micro-controller programming was all done in assembly or C, but in recent years higher level languages, included interpreted ones such as Python and JavaScript, have made their ways into MCUs with projects such as MicroPython or Espruino (JS) often running on STMicro STM32 ARM Cortex M micro-controllers, but also other platforms such as ESP8266. As I browsed through the Embedded Linux Conference Europe 2016 schedule, I discovered that Samsung worked on it own implementation of a JavaScript engine for the Internet of Things: JerryScript. It is a full implementation of ECMAScript 5.1 standard written in C that can run on micro-controllers with less than 64KB RAM, and less than 200KB storage (160KB footprint with ARM Thumb-2 compilation). JerryScript is comprised of two main components: Parser and Virtual Machine (VM), with the parser performing translation of input ECMAScript application into byte-code than is then executed by the Virtual […]

Embedded Linux Conference & IoT Summit Europe 2016 Schedule

Embedded Linux Conference & IoT summit 2016 first took place in the US in April, but the events are now also scheduled in Europe on October 11 – 13 in Berlin, Germany, and the schedule has now been published. Even if you are no going to attend, it’s always interesting to find out more about the topic covered in that type of events, so I had a look, and created my own virtual schedule with some of the sessions. Tuesday, October 11 10:40 – 11:30 – JerryScript: An Ultra-lightweight JavaScript Engine for the Internet of Things – Tilmann Scheller, Samsung Electronics JerryScript is a lightweight JavaScript engine designed to bring the success of JavaScript to small IoT devices like lamps, thermometers, switches and sensors. This class of devices tends to use resource-constrained microcontrollers which are too small to fit a large JavaScript engine like V8 or JavaScriptCore. JerryScript is heavily […]

Onion Omega2 is a $5 Linux WiFi IoT Board (Crowdfunding)

Onion Omega board was first introduced in 2015. The tiny OpenWrt Linux board featured an Atheros AR9331 processor with GPIO headers, and various baseboards and add-ons. The company has now launched a Kickstarter campaign for the second versions – Omega2 & Omega2 Plus – with a faster processor @ 580 MHz, compatible with docks and add-ons boards used for Omega, and a much lower price with $5 for the Omega2, and $9 for Omega2 Plus with more storage and memory. Omega2 & Omega2 Plus specifications: WiSoC – 580 MHz processor, possibly Mediatek MT7688 MIPS processor used in LinkIt Smart 7688 System Memory Omega2 – 64MB Omega2 Plus – 128MB Storage Omage2 – 16MB flash Omega 2 Plus – 32MB flash + micro SD slot Connectivity Built-in – 802.11 b/g/n WiFi with on-board and external antenna support Via add-on boards – Bluetooth 4.0 LE, GPS, and 2G/3G Expansion – 15x GPIO, […]

Review of PocketCHIP Hackable Handheld Linux Computer

It’s not that easy to describe PocketC.H.I.P in a couple of words, as it’s so versatile. It’s a Debian based portable Linux computer with a resistive touchscreen and battery, but also a retro gaming console thanks to PICO-8, as well as a hardware development platform for IoT application with expansion header providing access to I/Os including GPIOs, I2C, SPI, UART…, and WiFi and Bluetooth connectivity. Furthermore you can easily dismantle the device, in order to use the CHIP board, based on Allwinner R8 Cortex A8 processor, for a different project. So when Next Thing asked me if I was interested in reviewing Pocket CHIP, I was pretty excited, but when I received it, I scratched my head as there are so many ways to review the item, and it works out of the box with the firmware pre-loaded inside the internal flash, so a getting starting guide would have been […]
