Smart health gadgets will soon have a bigger part to play in our lives, especially for health monitoring. It mainly started with fitness trackers, but now we are starting to see connected devices such as blood pressure monitors, including the upcoming watch like Omron HeartVue, thermometer, scales, vital sign monitoring systems, certified medical SBC‘s to allow engineers to developer their own medical applications, and even open source surgical robots. HeartPatch is one of those medical board that specifically aims at measuring ECG data, and sent it over Bluetooth or WiFi thanks to Espressif ESP32 WiSoC. HeartPatch specifications: SoC – Espressif Systems ESP32 dual core Tensilica LX6 processor with Wi-Fi/Bluetooth ECG Chip – Maxim MAX30003 analog front-end USB – 1x micro USB connector for programming, data, power, and battery charging Debugging – USB-UART bridge based on CP2104 Misc – Onboard Snap-on Buttons for disposable electrode pads, RGB LED, Battery – 450 […]
Sonoff B1 Smart Light Bulb Review – Part 1 : eWeLink Android App and Teardown
ITEAD Studio has a popular family of home automation devices call Sonoff with WiFi switches, smart sockets, RF to WiFi bridges and so on. All WiFi devices are based on Espressif ESP8266 or ESP8285, and while the company provide a stock firmware working with eWelink app, at least two communities have formed around Sonoff and other similar devices providing two open source firmware alternatives: ESPurna and Sonoff-Tasmota. The company has sent me Sonoff B1 smart RGB light bulb for review. Today, I’ll check out the light with eWelink app for Android, and do a teardown, before trying one of the open source firmware in the second part of the review. Sonoff B1 Unboxing Some Chinese products come in a blank cardboard boxes, but Sonoff’s light bulb comes with in a nice looking retail package that would look good on store’s shelves. One of the side lists the specifications with an […]
Nokia 3310 3G Dumb Phone Works with 2G & 3G Networks
Many people use smartphones now, but “dumb” feature phones are still being sold, as they are cheaper, some may find smartphones too complicated to use, while others wary about privacy issues. However, most feature phones comes with 2G connectivity, and with 2G sunset in many countries, I’ve recently realized it’s not so easy to find a simple phone with 3G cellular connectivity. The good news is that Nokia 3310 3G has just been announced by HMD global. Nokia 3310 3G specifications: SoC – TBD System Memory – TBD Storage – 64 MB storage; MicroSD card slot supporting up 32GB Display – 2.4” QVGA (320×240) color display Keyboard – “beautiful push buttons and iconic, shaped design” Camera – 2MP camera with LED flash Audio – Headphone jack Cellular Connectivity 2G/ 3G connectivity: dual band 900/1800 MHz +3G Band 1 and 8 (Single SIM) quad band GSM 850/900/1800/1900 + 3G Band 1, […]

Short Demo with 96Boards SynQuacer 64-bit ARM Developer Box
Even if you are working on ARM platforms, you are still likely using an Intel or AMD x86 build machine, since there’s not really a good alternative in the ARM world. Linaro talked about plans to change that at Linaro Connect Budapest 2017 in March, and a few days ago, GIGABYTE SynQuacer software development platform was unveiled with a Socionext SynQuacer SC2A11 24-core Cortex-A53 processor, and everything you’d expect from a PC tower with compartment for SATA drives, PCIe slots, memory slots, multiple USB 3.0 ports, and so on. The platform was just demonstrated a Linaro Connect San Francisco right after Linaro High Performance Computing keynotes by Kanta Vekaria, Technology Strategist, Linaro, and Yasuo Nishiguchi, Socionext’s Chairman & CEO. If you have never used a system with more than 14 cores, you’d sadly learn that the tux logos at boot times will only be shown on the first line, skipping […]
Qt/QML vs HTML5/AngularJS User Interfaces Showdown (Video)
We now live in a world where there’s a push for higher level programming languages either based on web technologies like HTML5 or JavaScript, or other interpreted languages such as Python, and lower level languages such as C, C++, or – maybe more understandably – Assembler are often avoided by newcomers. But there are advantages of using native code, as demonstrated by Sequality, a software engineering company, who asked a developer familiar with HTML and C++ to develop a demo of an embedded systems using HTML5 + AngularJS and Qt/QML. The developer had 160 hours to develop the user interface for each framework, and with the resulting demos running on a Raspberry Pi 3 board with Raspbian, it was found that the Qt/QML implementation delivered a more responsive and functional user interface compared to the HTML5 version which tended to lag, and lacked support for touchscreen and a software keyboard […]
Linaro Connect SF 2017 Welcome Keynote – New Members, Achievements, the Future of Open Source, and More…
Linaro Connect San Francisco 2017 is now taking place until September 29, and it all started yesterday with the Welcome Keynote by George Grey, Linaro CEO discussing the various achievements since the last Linaro Connect in Budapest, and providing an insight to the future work to be done by the organization.

ARRIS Showcases Android TV Set-Top Boxes at IBC 2017
Just last week, we found out there was a fair amount of TV boxes running Android TV with certification from Google, with most of them from PayTV providers or OEMs. Today, I’ve come to better understand what that means thanks to ARMDevices.net interview of ARRIS at IBC2017. I used to think getting a device with official Android TV support would mean getting Google’s Leanback launcher, but there’s more to it, as Google also offers “operator tier” Android TV certifications, which allow manufacturer to use Android TV operating system with their own launcher/user interface, and official support for Google services like Google Play Store, Google Play Music and so on. ARRIS International has a whole family of certified Android TV devices with 4K UHD set-top boxes and DVR systems as shown in the table below, all likely based on Broadcom SoCs. Wi-Fi Set-Tops Wi-Fi Processor DMIPS Type Size Zx4430 2×2 802.11ac […]
