C.H.I.P Board and Allwinner A13/R8 SoCs To Get VPU Support in Linux Mainline

Allwinner has mixed relationships with open source communities such as Kodi, especially due to issues with its closed-source CedarX VPU drivers, and some GPL violations. However to address the former, linux-sunxi community has been working on open source Cedrus library for the video processor unit on Allwinner processors, that’s been successfully tested on boards such as Orange Pi One. Free Electrons has gone further, as they’ve made sure Cedrus now works with Linux mainline kernel, currently Linux 4.8, and tested it on Allwinner R8 based Pocket CHIP. The work has been done by Florent Revest, a 19 years old intern at the company, who delivered a new sunxi-cedrus driver, a Video4Linux (V4L2) memory-to-memory decoder kernel driver, and corresponding VA-API backend, with the implementations currently available on Github here and there respectively. Currently only MPEG2 and MPEG4 are working, but adding other codecs such as H.264, and video encoding is possible […]

Learn the Basics of Humanoid Robots with InMoov Finger Starter Kit

In a not so distant future, most humans will live off their government provided basic income, relaxing and drinking their robot brewed, drone delivered beer or soda, opened and served by their humanoid robot maid. Well, maybe… In the meantime, it might be interesting to learn how to make humanoid robots such as InMoov, but since it’s quite complicated, it might be better to start small… with a single finger. That’s exactly what InMoov Finger Starter Kit offers you to do in order to understand the basics principles of the complete robot. The kit includes: 1x 3D printed base support in ABS 3D printed finger parts in ABS 1 meter braided 200 LB tendon 1x 5cm filament for peg/pin use to assemble finger joints 1x wheel horn adapter (Servo Pulley) 4x screws to fix the servo to the base support. You’ll also need to provide your own Arduino Uno (or […]

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 […]

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 […]
