Mixtile GENA is a Wearables Development Kit Inspired by Pebble Watch

The first Pebble watch with a black and white e-Ink display and Bluetooth for smartphone connection launched in 2012 via Kickstarter, and it became one of the most successful crowdfunding campaigns so far. The watch can now be purchased for $100, but Focalcrest, a startup based in Shenzhen, designed Mixtil GENA development kit with similar features and user interface, although with different electronics components, that goes for $34 on Tindie. Mixtile GENA specifications: Processors Mediatek MT6260 ARM7EJ-S processor @ 364 MHz with 8MB RAM and 16MB Flash Nordic Semiconductor nRF51822 ARM Cortex M0 Bluetooth Smart SoC External Storage – micro SD card slot (Up to 8GB) Display – “Energy-saving” reflective LCD Connectivity – Bluetooth 4.0 LE USB – micro USB 2.0 port Sensor – Gravity sensor Misc – Up, Down, Enter and Power/Return buttons Battery – 270 mAh/3.7V Lithium-ion battery (4 to 5 days on a charge for typical usage) […]

$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 […]

Mifree HX-V5 Bluetooth Smart Fitness Tracker sells for $14

Mifree HX-V5 is a waterproof Bluetooth 4.0 activity tracker with fitness tracking and sleep monitoring functions just like Vidonn X5, except the device bring the price level to a new low, as it sells for just $14 including shipping on GeekBuying, and currently about $20 on Aliexpress, but there are few sellers, and more may come up around the $15 mark. HX-V5 smart band specifications differ depending on the sites too, not for the user exposed features, but for the internals [Update: GeekBuying told me they were given the wrong information, so I updated the specs accordingly): SoC – TI CC2541 Bluetooth SoC Storage – 4MB flash, enough to preserve 60 days of data Display – 0.91″ OLED display, 128×32 pixels Connectivity – Bluetooth 4.0 LE Sensors – 3-axis MEMS sensor IP Rating – IP67 (unlikely IMHO) Battery – 3.7V/70mAh Li-ion battery, good for 10 to 12 days. 2 to 3 hours charging time. Dimensions […]
