ThL W200 Smartphone Review (Mediatek MT6589T)

I’ve received ThL W200, a smartphone powered by Mediatek MT6589T SoC, at the beginning of week (Check specs and unboxing pictures), and after about a week of use, it’s time for a review. First I’ll go through my first impressions, test of different features such as the camera, GPS, and Bluetooth, and finally run some apps to get system information and benchmarks for this phone. ThL W200 Review This smartphone feels very light, but the build quality is good, and as explained in my unboxing post, comes with power, volume -/+, and menu/home/back buttons. You’ll also find rear camera + flash, front camera, the light sensor, and the notification light. First impressions The phone boots to the standard Android home screen, as shown above, with English as the default language, and comes with Google Play Store, and no Chinese apps. The 720p screen provide a sharp and clear display, and […]

LightBlue Cortado is an Arduino Compatible Board Programmed Wirelessly via Bluetooth LE (Crowdfunding)

We’ve already seen several Bluetooth Low Energy (BLE) Arduino compatible boards being crowd-funded such as RFDuino and BLEDuino, but there’s now another board designed by Punch Through Design: LightbBlue Cortado. The board is programmed wirelessly directly via Bluetooth LE, instead of USB as in the two aforementioned boards, which means programming via iPad or Android tablets becomes more convenient. Here are the technical specifications of the board: MCU – Atmel ATmega328P @ 8MHz with 32KB Flash, 1KB EEPROM, 2KB SRAM Bluetooth – LBM313 Module with Texas Instruments CC2540, 256 KB Flash. Bluetooth range: 30.5m. Power consumption in sleep mode: 0.9μA I/O – 4 PWM pins, 2 Analog inputs, 8 GPIO, I2C and SPI Sensor – 3-Axis Accelerometer Misc – RGB LED, protoboard section, adhesive backing Power – Coin cell battery. Battery life exceeding one year for low power applications There’s no USB, so the only way to program the board is via […]

ICMe Cuffless Finger Blood Pressure Monitor Sends Results to your Smartphone via Bluetooth 4.0

Nihon University have developed a tiny blood pressure monitor, which you can just touch with your finger, in order to get maximum and minimum (systolic and diastolic) blood pressures, both average and real-time values, as well as pulse rate and pulse waveform displayed on your smartphone. ICMe uses photo transistors to detect LED light reflected on a finger, and then converts pulse wave data obtained from the light to a blood pressure value. Phase Shift Method-based data processing and algorithm is used for the conversion to a blood pressure value, and results are transmitted to the phone via Bluetooth 4.0 (LE?). The device is composed of a custom main chip, LEDs, photo transistors, and a Bluetooth 4.0 module. Tech-on reports an early much larger model was exhibited last year at Medica 2013, and the new miniaturized model is currently showcased at Medica 2013, which runs from Nov 20 to 23, […]

Coin is a Smart Card that Replaces All Your Other Cards (Credit, Debit, Loyalty…)

You may have a few cards in your wallet: credit cards, debit cards, gift cards, membership cards, … and it’s just convenient to carry them around all the time. There will soon be a solution with Coin, a smart card where you can store all your other cards data, and use this smart card instead. In order to register your physical cards (up to 8 cards for one Coin), you’ll need to install an application in your Android smartphone, or your iPhone, take a picture of both sides of the cards, and swiping the Coin though a small device provided with the card. Then, when you want to make a purchase, you just click on the button of the Coin to select the card to use, and carry on with your purchase are you would normally do. You may worry about security concerns, but the company behind the Coin has […]

Ninja Sphere Home Automation and Monitoring Platform

Ninja Blocks is an company providing open source hardware solutions for home automation. Their first product was called Ninja Blocks Kit which includes a Ninja Block (Beaglebone + Arduino based gateway, but they now also support the Raspberry Pi), sensors, sockets, cables, and a power supply, and works with Ninja Platform, an open source software framework. The goal was to simplify the process of developing automation applications by taking care of all low levels tasks such as electronics, embedded programming, network protocols.., and letting “end users” / developers focus on their application. The company is now working on a new version called the Ninja Sphere, including a “Spheramid” gateway, location waypoints (Bluetooth low energy tags), and smart power sockets. Here are the key features of the gateway: Processor – ARM Cortex A8 (probably Texas Instruments Sitara) Color LED Matrix Connectivity – Bluetooth, Bluetooth LE, Zigbee, and Wi-Fi USB Port – […]

$219 Kwikset Kevo Bluetooth Low Energy Dead Bolt

With RFDuino, BLEDuino, SensorTag, etc…, we know have several low cost Bluetooth Low Energy development boards / kits, however there are just a few Bluetooth SMART peripherals available right now, although many are currently being developed. One application of BLE will be the ability to use your phone to interact with objects around you, and Kwikset has just done that with its Kevo BLE Deadbolt that can be pre-ordered for $219 on Amazon with delivery scheduled by the end of October 2013. All you need to do is to load Kevo mobile app unto your iOS or Android smartphone to turn it into an electronic key (eKey), and unlock the deadbolt by simply touching it with your finger without having to remove the phone from your pocket or purse. That looks highly practical, but at the same time very unsafe, so let’s have a look at some others features of […]
