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) […]
Beelink i68 (Rockchip RK3368) TV Box Review
Beelink i68 is one of the first 64-bit ARM Android mini PCs available on the market, and could offer an update to Rockchip RK3288 TV boxes thanks to its eight Cortex A53 cores and support for HDMI 2.0 up to 4K2K @ 60Hz. I’ve already taken a few pictures of the device and RK68 board, so today I’ll report about performance, stability, features and video playback capabilities in the full review. First Boot, Settings and First Impressions The box has three USB 2.0 host ports and a micro USB OTG port, so for once I did not have to use a USB hub to connect all my devices and cables. I’ve inserted an Ethernet cable, an HDMI cable, an optical cable to the S/PDIF output, a Class 10 micro SD card, a USB hard drive, a USB webcam, an RF dongle for Tronsmart Mars G01 wireless gamepad, and finally MeLE […]
Motion Controlled Bluetooth Ring Mouse Sells for $50
Some companies sells Ring Mice such as Genius Ring Mouse 2, which is an RF ring you place on your index finger and control with your thumb more or less like a trackball, but there are also new generation rings using motion control. One of the product is the latter category is Fin Bluetooth Ring which allows you to control your computer, phone ot car radio by simply touching various parts of your fingers, however it’s been funded via an Indiegogo campaign, and based on their latest update they have not shipped rewards to backers yet. But I’ve recently been informed about a “Smart 3D Bluetooth Ring” selling for around $50 on Ebay using motion control and some buttons to control computers and laptops. Specifications and features for the ring include: Connectivity – Bluetooth 4.0 LE Technology – “Human motion sensor” Working Distance – Within 10 meters Button – 3 […]
LightBlue Bean+ Bluetooth LE Board is Programmed Wirelessly, Lasts One Year on a Charge (Crowdfunding)
Punch Through launched a crowdfunding campaign back in 2013 for LightBlue Cortado an innovative Arduino compatible BLE board that can only be programmed wirelessly over Bluetooth Smart. The board has since then been renamed to LightBlue Bean, and the company allegedly delivered rewards to backers on time, a rarity in the crowdfunding world. LightBlue Bean+, the second version of the board, is larger with solderless headers, supports more Bluetooth LE capabilities such as MIDI, and includes a battery. The project launched on Kickstarter yesterday, and already raised over $40,000, surpassing the $30,000 funding target set by the team. LightBlue Bean+ board specifications: MCU – Info N/A (Bean has an Atmel ATmega328P @ 8MHz with 32KB Flash, 1KB EEPROM, 2KB SRAM) Bluetooth Bluetooth LE with support for 5 new capabilities: beacon, MIDI, HID, ANCS and observer role. Hardware module undisclosed (Bean has an LBM313 Module with Texas Instruments CC2540) Up to 400 […]
Espressif is Working on a New Wi-Fi and Bluetooth LE Chip with Hardware SSL Support
Espressif came to fame thanks to its low cost ESP8266 WiFi chip which was originally designed for connected lightbulbs, but soon got used in a variety of applications, and ESP8266 modules must now be the most popular solutions to add WiFi to IoT projects, as long as they are not battery powered. The company has recently announced they were working on a new chip, whose name as yet to be decided, that will support both Wi-Fi and Bluetooth Low Energy. Details are sparse, but we do know the chip will come with 500KB RAM, support hardware SSL and possibly ECDH, deliver 500 DMIPS of performance, and consume 5 uA in deep sleep mode. The company asked for beta testers via their twitter account around 2 weeks ago, so I guess it’s a bit too late to apply. John Lee, working for Espressif, also said the new part should become available […]
Simblee Low Latency Bluetooth LE IoT Module Loads Its App to Your Smartphone on Demand
RF Digital launched RFDuino Bluetooth Low Energy board in 2013/2014, and the company has now developed Simblee module, whose name is derived from “Simple” and “BLE”, and offers low latency (3ms) and integrates a user application that’s automatically and temporary loaded to your smartphone or tablet upon connection. The module is also part of an add-on board (RFD77201) for RFDuino board. Simblee RFD77101 module specifications: MCU – ARM Cortex M0 micr-controller (Nordic nRF51822???) Memory/Storage – 24KB RAM and 128KB flash for user application Bluetooth Smart / LE Bluetooth Low Energy (BLE) Stack Simblee interference immunity 3ms latency (for connection); 10us accuracy (jitter) -93dBm receiver sensitivity -55dBm to +4dBm TX power Physical range adjustable from a few inches to hundreds of feet Integrated antenna, integrated shield I/Os 29 GPIOs (flexible pin configuration) 6x ADC inputs 4x PWM outputs 2x SPI master/slave, 2x I2C, 1 x UART Security – Built in AES […]
$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 […]
