SMA-Q Bluetooth Smartwatch Features a Color E-Paper Display, an Heart Rate Monitor… for $56 and Up

My Vidonn X5 activity tracker died on me a few weeks ago about over a year of service. While it was useful to keep me active thanks to its “steps” counter, I realized I was not a big fan of OLED displays as they aren’t turned on all the time in order to save power, and are hard to read when there’s a strong sunlight, the battery did not last that long (about 2 days), and using motion sensors to evaluate activity is not that accurate. So I’m interested in wearables with always-on displays, readable in sunlight, that don’t suck too much battery (e.g one charge per week), and with a strapless heart rate monitor. The first three are normally only achievable with E-Ink or E-Paper displays and the latter have become much more common thanks to electro-optical heart rate monitors. I’m also a budget conscious guy, so I’d like […]

Bluboo Xwatch is an Android Wear Smartwatch Powered by Mediatek MT2601 SoC

So far, we’ve only seen Android Wear devices by large companies such as Motorola, LG, or Huawei, simply because you have to sign an agreement with Google in order to be allowed to load Android Wear on your device. Last year, a startup launched their own “Android Wear” watch on Indiegogo, but when Google found out the campaign got pull out since it was not going to happen. But the situation may have changed since then, as I’ve been contacted by Bluboo, which should be brand from Shenzhen Huihua Exploit Technology Co., Ltd, about their upcoming Bluboo Xwatch sports smartwatch running Android Wear, and the company confirmed they were “working with a third-party company to help them get this agreement”. I’m guessing/hoping the third party company might be Mediatek themselves. Bluboo Xwatch preliminary specifications: SoC – Mediatek MT2601 dual core ARM Cortex A7 @ 1.2GHz with ARM Mali-400 MP GPU […]

AMS AS7000 Biosensor is Designed for Strapless Optical Heart Rate Monitors

Heart rate monitors (HRM) with chest straps are now being replaced by more comfortable strapless HRM, such as UWatch UX. These products are enabled by photoelectric sensors that sample light modulated by blood vessels, which expand and contract as blood pulses through them. One of such solutions is the recently introduced AMS AS7000 including a Cortex M0 core, and a DSP implementing algorithm to process raw photoplethysmography (PPG) readings from the sensors to convert them into digital HRM and HRV (Heart Rate Variability) values. Highlights of AS7000 Biosensor: MCU – ARM Cortex M0 with 4KB RAM, 32 KB EEPROM I/Os – 9 GPIOs, UART, SPI, I2C Analog electrical and optical Frontends Hardware sequencer Synchronous detector Integrated LEd driver with current control Optical filters Supply Voltage – 2.6 – 3.6V Temperature Range –30 to 70°C Package – 18 pins AS7000 can deliver greater accuracy when it is paired with an external […]

$55 UWatch UX Strapless Heart Rate Monitor Watch Syncs with iOS and Android Devices

Last time I checked about heart rate monitor, they required a chest strap to monitor ones heart rate, which I found cumbersome. It’s been while though, and I’ve now been informed that a low cost Bluetooth strapless heart rate monitor watch was available for $59.99 on GeekBuying. This type of product should provide a much more accurate evaluation of your daily calories burn rate than typical fitness bands based on an accelerometer and gyro sensor, but I’m not quite sure how they compare to the old models with a chest strap. Uwatch UX specifications and features: SoC – Mediatek Aster MT2501 ARM7 processor @ 108 MHz (A lower end version of MT2502 used in LinkIt One Devkit) System Memory – 32MB RAM Storage – 24MB NOR flash Heart rate monitor – Built-in photoelectric heart rate sensor Other sensors – magnetometer, 3-axis gravity and acceleration sensor Connectivity – Bluetooth 4.0 and […]

FOSDEM 2015 Schedule – January 31 – February 1 2015

FOSDEM (Free and Open Source Software Developers’ European Meeting) takes place every year during the first week-end of February. This year the developer-oriented event expects to bring over 5000 geeks to share ideas and collaborate on open source projects. Contrary to most other events, it’s free to attend, and you don’t even need to register, just show up. FOSDEM 2015 will take place on January 31- February 1 in Brussels. There will be 551 sessions divided into 5 keynotes, 40 lightning talks, 6 certification exams, and with the bulk being developer rooms and main tracks, divided into 7 main tracks this year: Languages, Performance, Time, Typesetting, Hardware, Security and Miscellaneous. I’m not going to attend, but it’s still interested to see what will be talked about, and I’ve concocted my own little virtual program out of the main tracks and developers’ rooms. There’s a few minutes overlap between some talks […]
