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 […]

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 […]

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 […]

ZX Spectrum Next Retro Keyboard PC Relies on Xilinx FPGA, Raspberry Pi Zero “Accelerator” Board (Crowdfunding)

ZX Spectrum keyboard computer was launched in April 1982 in the United Kingdom, and 35 years later, a team of developers has now been working on ZX Spectrum Next somewhat resuscitating ZX Spectrum by emulating Z80 processor in a Xilinx FPGA, using an optional Raspberry Pi Zero board as an accelerator, and adding some modern features like HDMI output and WiFi. While the case is only a 3D rendering for now, they have a working board prototype with the following specifications: FPGA – Xilinx Spartan-6 FGPA emulating Z80 processor in 3.5Mhz and 7Mhz modes System Memory – 512KB RAM (expandable to 1.5MB internally and 2.5MB externally) Storage – SD Card slot, with DivMMC compatible protocol used in the original ZX Spectrum Video Hardware sprites, 256 colours mode, Timex 8×1 mode etc. Output: RGB, VGA, HDMI Audio – 3x AY-3-8912 audio chips with stereo output + FM sound Networking – Optional […]

GPU Accelerated Object Recognition on Raspberry Pi 3 & Raspberry Pi Zero

You’ve probably already seen one or more object recognition demos, where a system equipped with a camera detects the type of object using deep learning algorithms either locally or in the cloud. It’s for example used in autonomous cars to detect pedestrian, pets, other cars and so on. Kochi Nakamura and his team have developed software based on GoogleNet deep neural network with a a 1000-class image classification model running on Raspberry Pi Zero and Raspberry Pi 3 and leveraging the VideoCore IV GPU found in Broadcom BCM283x processor in order to detect objects faster than with the CPU, more exactly about 3 times faster than using the four Cortex A53 cores in RPi 3. They just connected a battery, a display, and the official Raspberry Pi camera to the Raspberry Pi boards to be able to recognize various objects and animals. The first demo is with Raspberry Pi Zero. […]

Yundoo Y8 (Rockchip RK3399) TV Box Review – Part 1: Unboxing and Teardown

Rockchip first unveiled RK3399 hexa-core processor at the beginning of 2016, but we had to wait longer than expected to get devices to play with. The first retail product based on the processor is really Samsung Chromebook Plus, and we only saw a few TV boxes for pre-sale in January such as Yundoo Y8 or R-TV Box K99, and with the first shipments occurring in March. However, I’ve also noticed many companies postponed the launch of the RK3399 mini PC/TV box, and no company contacted me for review so far, so I had no rush because that probably means the boxes were not quite ready. But starting at the beginning of next month, more companies will start selling their model, and GearBest proposed to send me Yundoo Y8 model with 4GB RAm, 32GB flash, and decided to give it a go. In this first part of the review, I’ll only […]

The Cheapest MP3 Players Are now Selling for Under $1 including Shipping…

Most of us now listen to music on the go using our phones, but once upon a not-so-distant time, portable MP3 players were a popular way to listen music. They have not completely disappeared, and Brad Linder of Liliputing needed some for one of his projects, so he bought four inexpensive MP3 players on GearBest with prices ranging from $1.51 to $3.75 to check them out. It turns out the one with the best audio quality and sturdiness was Simplicity Fashion Pocket MP3 Player going for $1.51 shipped. So let’s see what we get for that price: Audio – 3.5mm audio jack Storage – micro SD slot up to 16GB (no internal storage) USB – mini USB port for charging, and connect to PC which detects the MP3 player as an SD card reader (but it’s rather slow) Misc – Power, volume, next, previous, and play/pause buttons; metal clip; power […]
