Smartwatch for the Blind – Dot Watch Supports Braille Language, Sync Data over Bluetooth

A South Korean company has created Dot smartwatch specifically designed for the blinds and visually impaired, as it supports Braille language through 24 dots that move up or down depending on the data to show. Like other smartwatches, it will also pair with a smartphone, and received notifications over Bluetooth to Android and iOS smartphones. Dot watch specifications: Wireless MCU – 32-bit ARM Cortex M4F + Cortex M0 microcontroller “Display” – 4 Dot Cells (24 Dots) made of 6000 series silver aluminum Connectivity – Bluetooth LE 4.2 Misc – 24 touch sensors, shaft horizontal vibration motor, a crown, two buttons Battery – 400mAh li-polymer battery good for a typical 7 days on a charge Dimensions – Watch: 43mm x 12.5mm; Leather band – S size: 22x220mm; M size: 22x250mm; L size: 22x290mm Weight – 27g This is all made possible through the company’s dot rotor technology that allows to move […]

Getting Started with ESP32-Bit Module and ESP32-T Development Board using Arduino core for ESP32

Espressif ESP32 may have launched last year, but prices have only dropped to attractive levels very recently, and Espressif has recently released released ESP-IDF 2.0 SDK with various improvements, so the platform has becomeĀ  much more interesting than just a few weeks ago. ICStation also sent me ESP32-T development board with ESP32-bit module, so I’ll first see what I got, before trying out Arduino for ESP32 on the board. ESP32-T development board with ESP-bit Module – Unboxing & Soldering One thing I missed when I asked for the board is that it was not soldered, and it comes in kit with ESP32-bit module in one package, and ESP32-T breakout board with headers in another package. The 21.5x15mm module is based on ESP32-DOWNQ6 processor with 32 Mbit (4MB) of flash, a chip antenna, and a u.FL connector. The module is apparently made by eBox, and also used in Widora board with […]

Packet 96-core Cavium ThunderX Baremetal ARMv8 Servers are Available for $0.50 per Hour, $372 per Month

Last week, I wrote about Scaleway ARMV8 cloud servers powered by Cavium ThunderX processors. They are very cheap, as low as 0.0006 Euros per hour or 2.99 Euros per month, but you only get access to 2 to 8 cores, so obviously you don’t get a baremetal server for that price.Ā  If you want the latter Packet.net has been offering just that since the end of last year with their Type 2A baremetal server with two Cavium ThunderX 48-core processors, 128 GB RAM, 384 GB SSD and 20 Gbps bandwidth. The servers can currently run Centos 7, CoreOS, Ubuntu 16.04 LTS,Ā  with support for container platforms such as CoreOS Tectonic, Rancher, Docker Cloud, ContainerShip, StackEngine, Docker Machine, etc… You can check the status for other operating systems and features and the roadmap page. They also have x86 servers, and I’ve included the hourly and monthly prices and features for all […]

AIY Projects Voice Kit Transforms Raspberry Pi 3 Into Google Home, Comes Free with Raspberry Pi Magazine

We’ve just reported about the preview release of Google Assistant SDK that works on the Raspberry Pi 3, and other boards with a microphone, speakers, and access to Internet. The Raspberry Pi foundation and Google have now made it even easier, as they launched AIY Projects Voice Kit with a Google Voice HAT, a speaker, a stereo microphone Voice HAT board, a button, a few cables, and a cardboard case. You’ll just need to add your own Raspberry Pi 3, follow the instructions to assemble kits, load and setup the software. Once this is all done, you’ll be able to press the top button, asking anything you want to Google Voice, including the weather. Price? Sort of free, as it comes with MagPi 57 magazine, where you’ll also find detailed instructions for the kit. Google AIY Projects got its name from a mix between (DIY) and artificial intelligence (AI), and […]

SinoVoIP Releases $35 Banana Pi BPI-M2+ Board with Allwinner H2+ Processor

Banana Pi BPI M2+ board was first released with Allwinner H3 processor, but the same PCB can also be used with Allwinner H2+ and H5 processors since the processors are pin-to-pin compatible, and SinoVoIP intends to release three version of the board, and just launched BPI M2+ (aka BPI H2+) with Allwinner H2+ processor for $34.50 + shipping, $1.5 cheaper than the H3 version also listed on Aliexpress. If you shop around, and don’t order on the official SinoVoIP store, you may find cheaper price for the boards. As expected, the specifications have not changed apart from the processor: SoC – Allwinner H2+ quad core Cortex A7 @ 1.2 GHz with an ARM Mali-400MP2 GPU up to 600 MHz System Memory – 1GB DDR3 Storage – 8GB eMMC flash, micro SD card slot up to 64GB, Video & Audio Output – HDMI with CEC support Connectivity – Gigabit Ethernet, 802.11 […]

VolksPC OS Runs Android and Debian Simultaneously on ODROID-C2 Board

Most development boards and some TV boxes offer a dual boot image with Android and a Linux distribution. To run an Android app, you need to boot to Android OS, and if you decided you need to run Linux, you then need to reboot to the Linux OS, and you can’t simply use Alt+Tab to easily and quickly switch between Android and Linux apps. But VolksPC offers just that: the ability to run Android and Debian side-by-side, and I tested their MicroXWin unified distributions with MK808B TV stick powered by Rockchip RK3066 processor a few years ago. It was early stage at the time (July 2014), and there was some stability issues.The company has kept working on their solution, but focused on more powerful hardware, and they have now released VOLKSPC OS for ODROID-C2 with Debian XFCE and Android Marshmallow, which will run both Android and Debian applications at the […]

$97 MXQ HF10 Android Bluetooth Speaker & TV Box Works with Amazon Alexa

Last fall, I wrote about Eny Technology HF10, a 2-in-1 Android 6.0 TV box & Bluetooth speaker powered by Amlogic S905X processor, but at the time it was still under development, and we did not know all the features. The device has now been launched under the MXQ brand with support for Amazon Alexa voice service, and is up for pre-order for $96.55 on GearBest. MXQ HF10 specifications: SoC –  Amlogic S905X quad core ARM Cortex-A53 @ up to 1.5 GHz with Mali-450MP GPU System Memory – 1GB DDR3 Storage – 8GB eMMC flash + micro SD slot up to 128 GB Video Output – HDMI 2.0a up to 4K @ 60 Hz Audio HDMI output 2.5″ 10W mono bass speaker with class-D amplifier Connectivity – 10/100M Ethernet, dual band 802.11 b/g/n/ac Wi-Fi, and Bluetooth 4.0 USB – 1x USB 2.0 host port Misc – Power & Play/Pause combo button, […]

$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 […]
