Sonoff G1 AC Powered Smart Power Switch Works Over 2G GSM/GPRS

Today, I’ve searched for AC powered wireless switched similar to Sonoff devices, but with ESP32 instead in order to get WiFi and Bluetooth, since the latter is better to use with a battery powered buttons. I did find a DC powered board, but no AC powered ones yet. However, as I visited ITEAD website to check if they had anything of the sort, I discovered they had a new model called Sonoff G1, similar to Sonoff TH16, but instead of using WiFi, you can use 2G GSM/GPRS to control the switch remotely. Sonoff G1 specifications: Wireless Module – ST86 quad band GSM/GPRS module GSM/GPRS connectivity GSM850, EGSM900, DCS1800 and PCS1900 MHz support GPRS multi-slot class 10, GPRS mobile station class B 1.8V, 3V SIM card slot Transmit power: Class 4 (2W): GSM850, EGSM900; Class 1 (1W): DCS1800, PCS1900 Relay – Up to 16A (3000 Watts max) Terminals – 6 terminals […]

Lingmo Translate One2One Earpiece Can Interpret 8 Languages with IBM Watson Natural Language & Translation APIs

Automation are greatly reduce the number of workers requires to perform manufacturing, and now technology is moving forward with artificial intelligence applications writing financial & sports news, analyzing medical imaging or other data to speed up and improve accuracy of diagnostics, and more. Yesterday, I found out that pair programming, which normally combines two human programmer working together on the same program, may soon pair a human programmer with an AI programmer helping selecting the best code, and today I found out live interpreters may get some competitions with products like Lingmo Translate One2One earpiece that can interpret 8 languages nearly in real-time. The device was unveiled at the United Nations Artificial Intelligence (AI) for Good Summit in Switzerland, as it combines IBM Watson’s Natural Language and Language Translation APIs, together with Lingmo’s proprietary hardware and machine learning applications. It’s said to be working as an independent device without the […]

$59 HDFury Universal PSU Doctor Supports Power Monitoring via iOS or Android

We’ve recently covered Cambrionix PowerPad 15S, a high-end 16-port USB hub that can deliver 5V/2.1A on each port, integrates power monitoring function, and an API to control and monitor each port individually. That’s a very cool device, but it’s also expensive at around $600, and even the cheaper PowerPad 15C without data pins, come at $200. If you don’t need the complete set of features offered by Cambrionix devices, but you’ll like to get a reliable multi-port USB charger with power monitoring function, HDFury Universal PSU Doctor could be an interesting option. HDFury Universal PSU Doctor specifications: MCU – Renesas RL78 16-bit MCU USB – 3x USB ports with 2x 5V ports up to 5V/2.14A, 1x USB QC 2.0 port supporting 5V/2.14A, 9V/1.6A or 12V/1.2A output ADC – Up to 11 channels, 10-bit resolution for power monitoring Sensor – n-chip temperature sensor Power Supply Built-in 100 ~ 240V AC with […]

Texas Instruments CC3200 WiFi SensorTag is Now Available for $40

Texas Instruments launched SensorTag in 2013, and at the time there was just a Bluetooth 4.0 LE version with 6 different sensors. I bought one for $25 at the time, and tried it with a Raspberry Pi board and a BLE USB dongle. Since then, the company has launched a new multi standard model (CC2650STK) supporting Buetooth low energy, 6LoWPAN, and ZigBee, and has just started to take orders for CC3200 WiFi SensorTag for $39.99, which seems expensive in a world of $2 ESP8266 modules. But let’s see what the kit has to offer: Wireless MCU – Texas Instruments CC3200 SimpleLink ARM Cortex-M4 MCU @ up to 80 MHz, with up to 256KB RAM, Hardware Crypto Engine, DMA engine Storage – 1 MB serial flash memory Connectivity – 802.11 b/g/n WiFi with on-board inverted-F antenna with RF connector for conducted testing Sensors – Gyroscope, accelerometer, compass, light sensor (OPT3001), humidity […]

Omron Project Zero 2.0 is a Thinner Wrist Blood Pressure Monitor & Smartwatch

Omron Project Zero BP6000 blood pressure monitor & smartwatch / fitness tracker was unveiled at CES 2016. The device was due to be released at the end of 2016 pending FDA approval, but the launch has now been delayed to spring 2017, and it will be sold under the name “HEARTVUE”. The company has however showcased a new version at CES 2017, for now just called Omron Project Zero 2.0 that has the same functions but is more compact and lightweight. The watch will also work with Omron Connect US mobile app, and can record accurate blood pressure, as well as the usual data you’d get from fitness trackers including activity (e.g. steps) and sleep, as well as smartphone notifications. Blood pressure measurement can be activated by the user by pressing a button and raising his/her wrist to the height of the chest. The goal is the same as the […]

You Can Buy AirPods-like Wireless Bluetooth Stereo Earbuds for $16 and Up

Most Bluetooth headsets on the market actually come with some sort of wire or holding mechanism, which may not always be convenient, for example I can’t use mine comfortably while lying down on the bed. But that to electronics miniaturization, companies have recently started to offer truly wireless Bluetooth earbuds, including Apple’s yet-to-be available $159 Airpods. This morning I noticed two similar products in new arrivals list, first with $59.99 QCY Q29 mini Earburds on GeekBuying, and then even cheaper, but not quite as good looking (and likely not so good sounding), “FreeStereo Twins Wireless Bluetooth v4.1 In-Ear Headset w/ Mic” on DealExtreme going for just $22.25 including shipping. Let’s start with QCY Q29 earbuds specifications: Connectivity – Bluetooth 4.1 with HFP, HSP, A2DP, AVRC protocols support; up to 5-10 meter range Built-in Microphone Charging port – pogo on earbuds, micro USB to storage/charging box Battery – 45mAh for up […]
