Huawei Introduces Kirin 970 Mobile SoC with Built-in Neural Processing Unit for Artificial Intelligence Applications

Huawei has unveiled their latest Kirin 970 SoC for premium smartphone at IFA 2017. The processor features an 8-core CPU, and a new 12-core GPU, but what makes this new processor stands apart it a dedicated Neural Processing Unit (NPU) to accelerate tasks used for artificial intelligence, with the company claiming the NPU delivers 25 times the performance with 50x greater efficiency compared to a quad core Cortex A73 processor for AI computing tasks. In practical terms, Kirin 970 could process 2,000 images per minute in an unnamed benchmark image recognition test. The press release also mentions the processor will pack 5.5 billion transistors packed into 1 cm² and be manufactured using a 10nm “advanced processor”. But they did not go into much further details about the specs, so instead, I used info from Anandtech and the slide above to derive Kirin 970 technical specifications: CPU – 4x ARM Cortex […]

2017 Tevo Tarantula Dual Extruder 3D Printer Review – Part 2: Auto-Leveling, Dual Color Prints, Flex Filament

Karl here with final part of Tevo Tarantula dual extruder 3D printer review. The kit that was sent by Gearbest has a large bed, auto leveling, dual extrusion, and flex extruder of which I only found the flex extruder appealing to me. I have had this printer for a while now. It was relatively easy to setup, but near the end of the build it did not cover every aspect. There are lots of videos and a big Facebook group if you run into any troubles. Overall it is a good printer, but some of the features I initially thought I would like turned out to not be very useful. Auto leveling I tried my hardest to get this to work even going as far as to upgrade the firmware, but because they had a printed bracket on it, it drooped on my first high temp ABS print. I removed […]

AutoPi is a 4G & GPS OBD-II Dongle Based on Raspberry Pi Zero W Board (Crowdfunding)

We’ve previously covered Macchina M2 OBD-II dongle based on an Arduino compatible MCU, and with 4G LTE support for the maker market, and iWave Systems OBD-II dongle with 4G LTE and LTE running Linux on NXP i.MX6 for the B2B market, but so far I had not seen an hackable OBD-II dongle running Linux for the maker market. AutoPi dongle fills that void as it is based on Raspberry Pi Zero W board, runs Raspbian with Autopi software (AutoPi Core), supports 4G LTE, GPS, etc,.. and connects to your car’s OBD-II socket. AutoPi dongle specifications: SoC – Broadcom BCM2835 ARN11 Core processor @ up to 1 GHz System Memory – 512MB LPDDR2 SRAM Storage – 8GB micro SD card Cellular Connectivity 4G Cat 1 modem with 3G/EDGE fallback working worldwide (but region locked) 4G bands – Region specific 3G fallback (WCDMA) – B1, B2, B4, B5, B8 EDGE fallback – […]

Google Assistant News – AIY Voice Kit For Sale, Offline Support, 3rd Party Smart Speakers Announced

There’s been a lot of development related to Google Assistant in the last few days. First, Google provided an update for AIY Projects, with their AIY Projects Voice Kit now available for pre-order on Micro Center for $35 including a Raspberry Pi 3 board, making the kit virtually free, although you may also purchase it. Note that Micro Center blocks traffic originating from some countries, so I had to use Zend2 to access the site. [Update 10/09/2017: You can also get it from Seeed Studio for worldwide shipping] Google also announced the Speech Commands Dataset with 65,000 one-second long utterances of 30 short words, which they are in the process of integrating with the next release of the Voice Kit, and will allow the devices to respond to voice commands without the need for an Internet connection. So if you lose your Internet connection, or want to isolate your Voice […]

LoFive is a Tiny Open Source Hardware Board based on SiFive FE310 RISC-V Open SoC

Do you remember HiFive1? It’s an Arduino compatible board based on the SiFive FE310 open source RISC-V SoC. Michael Welling has now started working on LoFive board using the same processor, but in a much smaller & breadboard friendly form factor. LoFive board specifications: MCU – SiFive Freedom E310 (FE310) 32-bit RV32IMAC processor @ up to 320+ MHz (1.61 DMIPS/MHz) Storage – 128-Mbit SPI flash (ISSI IS25LP128) Expansion – 2x 14-pin headers with JTAG, GPIO, PWM, SPI, UART, 5V, 3.3V and GND Misc – 1x reset button, 16 MHz crystal Power Supply – 5V via pin 1 on header; Operating Voltage: 3.3 V and 1.8 V Dimensions – 38 x 18 mm (estimated) The board will be programmable with Arduino IDE + Cinco just like HiFive1 board. The board is also open source hardware, so beside the aforelinked info on Hackster,io, you’ll also find the KiCAD schematics, PCB layout, and […]

Those Charts Show The Benefits of Microphone Arrays for Hot Word Detection

Since I started looking more into smart speakers, including DIY ones such as the I made with Orange Pi Zero board + Google Assistant with a single microphone, I was told about the importance of microphone arrays, but so far, I had not seen any clear study or data about that. That changed today, as I came across a review of mic arrays by the makers of Snips Voice Platform. They tested five arrays connected to a Raspberry Pi 3 with the system, and also added a generic USB microphone to the mix. The results speak for themselves… In that experiment, they measured the rate at which a hot word was successfully detected by incrementally increasing the distance between 0.5 meters to 5 meters (16 ft), and for each distance, repeating the hot word 25 times at 3 second intervals using pre-recording to keep the voice level constant, and the […]

8K VR Headsets Are Coming, Starting with Pimax 8K

The user experience with current virtual reality headsets is far from ideal, because of a lack of content, the “screen-door effect“, and the screen resolution is not quite high enough since it’s so close from our eyes. 8K virtual reality headsets, with 4K per eye, should make the experience both more realistic, and minimize the screen-door effect. One of the first such products will be Pimax 8K VR headset. It’s still a prototype that the company will showcase at IFA Berlin 2017, but we already know that beside a twin 3840 x 2160 pixel display, it will also have a 200 degree field of view, and 18 ms MTP (Motion-to-Photon) latency. The headset will ship with two motion controllers to track your movements. With the kind of processing power required to handle 8K, it’s not a standalone headset, and instead will rely on (Windows) computers with NVIDIA GeForce GTX980 or […]
