Google Assistant SDK Turns Your Raspberry Pi 3 into Google Home

Google Home allows you to select music, control your home automation system and more with voice commands, but now you can do the same with a Raspberry Pi 3 as Google released a developer preview (alpha v1) of the Google Assistant API that works on Raspberry Pi 3, and other development boards running Debian or Ubuntu. Functionalities are limited right now, with RPC API and Python sample code, but it only works with English language, and features such as timers & alarm, playing music, news, or podcasts, and precise location are not supported. Location is determined using your IP address only, and if you’re using some third party services / products such as Uber or Hue, you’ll need an actual Google Home device for initial setup. Google has provided instructions to use Google Assistant SDK with Raspberry Pi 3 board. First you’ll need a USB microphone ($5.99 on Amazon), and […]

Yundoo Y8 Rockchip RK3399 mini PC Review – Part 2: Android Firmware, Audio & Video Playback in Kodi

Yundoo Y8 is one of the first Android TV boxes / mini PCs powered by Rockchip RK3399 hexa-core processor to be launched. GearBest sent me a review sample, and since I’ve already taken it apart in the first part of the review, I’ll report my experience with the firmware in terms of stability and performance, as well as audio & video capabilities with TVMC (Kodi fork), and more. First Boot, Setup, and First Impressions I’ve first connected a few peripherals Seagate USB 3.0 drive to the USB port, a USB keyboard to one of the USB 2.0 port, and a USB hub to the other one with two USB RF dongles for MINIX NEO A2 Lite air mouse, and Tronsmart Mars G01 gamepad. After adding Ethernet and HDMI cable, I pressed the power button on the unit to start it up. Please note that the remote control cannot turn on […]

Does That Crane or Drilling Rig Run mainline Linux?

Linux 4.11 has just been released, and as usual I looked into the changelog especially checking out work done on ARM architecture, and some newly supported SoCs or board. One line in the log caught my attention:  “Liebherr (LWN) monitor 6 based on i.MX6 Quad, no idea what this is”. So I had a look, and Liebherr-Werk Nenzing GmbH is a swiss company specializing in construction machines and maritime cranes such as “crawler cranes, duty-cycle crawler cranes, as well as piling and drilling rigs”. The DTS file for LWN Monitor 6 shows an NXP i.MX 6Quad processor is used in a product with an LVDS display and various interfaces such as I2C, PWM, SPI, and so on. So it could be some kind of control panel for one or more of their equipment. After looking into some PDF documentation, we can see  on page 10 that the company mentions Litronic […]

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 […]

GPU Accelerated Object Recognition on Raspberry Pi 3 & Raspberry Pi Zero

You’ve probably already seen one or more object recognition demos, where a system equipped with a camera detects the type of object using deep learning algorithms either locally or in the cloud. It’s for example used in autonomous cars to detect pedestrian, pets, other cars and so on. Kochi Nakamura and his team have developed software based on GoogleNet deep neural network with a a 1000-class image classification model running on Raspberry Pi Zero and Raspberry Pi 3 and leveraging the VideoCore IV GPU found in Broadcom BCM283x processor in order to detect objects faster than with the CPU, more exactly about 3 times faster than using the four Cortex A53 cores in RPi 3. They just connected a battery, a display, and the official Raspberry Pi camera to the Raspberry Pi boards to be able to recognize various objects and animals. The first demo is with Raspberry Pi Zero. […]
