Google Assistant SDK Now Supports Device Actions, More Languages (French, German, Japanese)

Back in May 2017, Google released the Assistant SDK that worked on Raspberry Pi 3, and other ARM boards, essentially transforming low cost development boards into Google Home equivalent. The SDK became more popular once Google’s AIY Voice Kit was launched since it offered an easy and inexpensive way to use it with Raspberry Pi 3 board. Since all you need was a Linux board with an Internet connection, a microphone, and speaker, I tried Google Assistant SDK on one of the cheapest platform available: Orange Pi Zero Set 6 Kit including Orange Pi Zero board, but also an expansion board with built-in microphone and audio output jack, and a cute little case. I added my own pair of speakers, micro SD card, and USB power supply, and after setting up the software, I was able ask question, and get answers with female voice using the demo app. At the […]

Orange Pi One Plus Allwinner H6 Board Launched for $20

Allwinner H6 is a processor designed for 4K HDR set-top boxes such as Zidoo H6 Pro, but with USB 3.0, Gigabit Ethernet, and PCIe interfaces, the processor is also a good candidate for ARM development boards where you need fast I/Os. I was expecting Orange Pi 3 Plus as the first board based on the processor, but instead Shenzhen Xunlong has just launched a cheaper Orange Pi One Plus version that sells for $19.99 plus shipping. Orange Pi One Plus specifications: SoC – Allwinner H6 V200 quad core Cortex A53 processor with Arm Mali-T720MP2 GPU System Memory – 1 GB LPDDR3 Storage – micro SD card slot up to 32GB Video & Audio Output – HDMI 2.0a up to 4K @ 60 Hz with HDR, HDCP, CEC Connectivity – Gigabit Ethernet (via Realtek RTL8211 transceiver) USB – 1x USB 2.0 host port, 1x micro USB OTG port Expansion – 26-pin […]

Garmin Launches Vivofit 4 Activity Tracker with One Year Battery Life

I have not spent much time covering wearables like smartwatches and fitness trackers this year, mostly because I find they have too many flaws at this stage. Back in 2016, I found many had a short life time, they would just stop working after a few weeks or months, even the fairly popular Xiaomi Mi Band 2 only lasted 2 months after an ill-fated firmware upgrade. In my case, I also found activity / fitness trackers did not have the motivating factor I thought they’d have, so I don’t think I exercise more or less with one. Finally, another annoyance is that most need to be charged every couple of days or weeks, and I’m frequently leaving the one I’m still using (SH09) run out of battery, losing recent data. The best solution to address the latter issue would be some type of energy harvesting, so that we would never […]

Help Testing TLS 1.3 Compatibility for a More Efficient & Secure Internet

Transport Layer Security (TLS) is the protocol that allows for secure websites (via https), and currently, TLS 1.2 is the version most commonly used today, with 1.0 and 1.1 still supported by many servers for backward compatibility with older browsers, including the one running this blog. TLS 1.3 is the next version, already supported in libraries and server software such as wolfSSL or nginx, and promises to be more efficient – important for battery operated devices (IoT) – thanks to features like zero-RTT (0-RTT) mode, speedy with a restructured handshake state machine, and more secure. However, changes in security protocol may mess up connection with some browsers or middleboxes, as I experience when I enabled https on CNX Software using Let’s Encrypt with nginx and Cloudflare, with around 0.5% of users losing access due to using older web browsers and operating systems such as Internet Explorer on Windows XP. According […]

More Details about Goldmont Plus Microarchitecture (used in Gemini Lake Processors)

2017 was the year of systems based on Intel’s low power, low cost Apollo Lake processors, and provided Intel does not suddenly decide to cancel yet another product, they will be replaced by Gemini Lake processors in 2018. The former is based on Goldmont microarchitecture, while the latter relies on the updated Goldmont microarchitecture. Intel has now released a document entitled “Intel 64 and IA-32 Architectures Optimization Reference Manual” where you’ll find more gritty technical details about Goldmont Plus in chapter 16 “SOFTWARE OPTIMIZATION FOR GOLDMONT PLUS, GOLDMONT, AND SILVERMONT MICROARCHITECTURES”. The enhancements over Goldmont include: Widen previous generation Atom processor back-end pipeline to 4-wide allocation to 4-wide retire, while maintaining 3-wide fetch and decode pipeline. Enhanced branch prediction unit. Improved AES-NI instruction latency and throughput. 64KB shared second level pre-decode cache (16KB in Goldmont microarchitecture). Larger reservation station and ROB entries to support large out-of-order window. Wider integer execution […]

ALio Proto Board Supports Through Hole, DIP, and SMD Components (Crowdfunding)

Perfboards and stripboards are very useful to design your own simple electronic boards without having to design your own board from scratch. However, you have to select through hole or DIP components, as – while possible with some efforts – such boards are not designed for SMD components. AERD, an open source electronic development startup based in Indonesia, has designed ALio prototyping boards supporting both through hole and SMD components, as well as some common connectors/accessories such as micro SD card, USB connector, and so on. Three versions of the board (basic, embedded, Arduino) are available with the following specifications & features: Fits SMD and PTH components at the same time. Double layer bus (top and bottom) Other components/headers All versions – 1.1 mm pitch pad for micro SD/SD card breakout Embedded & Arduino only – mini & micro USB pads, 1x SPI breakout Arduino only – Arduino header, one […]

$17 Sonoff S31 Wireless Smart Socket Includes Energy Monitoring Function

ITEAD Studio has just launched another Sonoff Smart Home product with Sonoff S31 WiFi smart socket with energy monitoring. Just like Sonoff switches, light bulbs, and their other products, the device can be controlled using eWelink app for Android or iOS, and supports integration with Amazon Alexa, and Google Assistant. It should be noted that the company only provide a US plug version for now, and so far, there’s no Wiki link, so while it’s likely based on ESP8266 or ESP8285 like their other Sonoff devices, it may not be designed to be easily hackable, although I suspect the electronics may be similar to Sonoff POW switch (TBC). Sonoff S31 hardware specifications listed by ITEAD: Voltage Input – 90~264V AC, 50/60HZ Max. Current – 16A Max. Power – 4200W (Note package above reads max load: 220V/10A) Gang – 1x US type with ground Connectivity – 802.11 b/g/n WiFi with support […]
