OpenThread is an Open Source Implementation of Thread IoT Networking Protocol

Thread was announced about two years ago, as a new IP-based wireless protocol based on 6LoWPAN and 802.15.4 standards and targeting IoT applications. Nest Labs, an Alphabet company, has now released OpenThread open-source implementation of the networking protocol under a BSD license. The source code (C++) for OpenThread includes supports for End Device, Router, Leader & Border Router roles, and can be found on Github. The implementation is said to be OS and platform agnostic with a radio abstraction layer, have a small footprint, and implement all Thread networking layers, namely IPv6, 6LoWPAN, IEEE 802.15.4 with MAC security, Mesh Link Establishment, and Mesh Routing. To quickly get started, you may want to read the Examples README which explains how to build the code, start two nodes, and ping them. Interestingly, while the code is there for everybody to use, only paid members ($2,500 to $100,00) of the Thread group can […]

Wintech SCT-R225 Plays and Converts Cassette Tapes and FM/AM Radio to MP3 on micro SD and USB Drives

Just last week, I wrote about a standalone vinyl to MP3 recorder, but another Japanese company has now launched a cassette tape and FM/AM radio player that can also record to MP3 on micro SD cards or USB flash drives. Wintech SCT-R225 specifications: FM/AM radio tuner with retractable antenna Cassette tape player Audio – Speaker and microphone, headphone jack Digital storage – 1x USB host for USB flash drives, 1x micro SD slot Misc – Control buttons Power supply – 100V AC to 6V DC power adapter or 4x AA batteries Dimensions – 188 x 36 x 98 mm Weight – ~ 406g without batteries One downside is that if you want to record FM radio to MP3, it would have to be recorded on a tape first, then from the tape to MP3. The tape to MP3 conversion also handles silence detection in order to record each song on […]

VoCore2 WiFi IoT Module Features Mediatek MT7628AN Processor

When Vocore WiFi module launched in 2014 on Indiegogo, it quickly became popular as at the time it was hard to find cost effective and small WiFi modules with GPIOs, and its compact Ethernet dock solution was also a hit. The developer has now been working on VoCore2 for several months, and recently announced a beta testing program. Vocore2 preliminary specifications: SoC – Mediatek MT7628AN MIPS processor @ 580 MHz System Memory – 64 or 128 MB DDR2 Storage – 16MB NOR FLASH, 1x SDXC via I/O pins Connectivity – WiFi 802.11n 2T2R up to 300 Mbps with either 2 u.FL connector or 1 u.FL connector + on-board chip antenna (Max signal output >19.5dbm peak); 2x 10/100M Ethernet interfaces via I/O pins I/Os – About 30 GPIOs multiplexed with 3x UARTs, 1x I2C, 1x I2S, 1x reference clock, 1x USB 2.0, 1x PCIe 1.1, 1x high speed SPI (40Mbps max), […]

Arduino Yún Shield Adds Ethernet and WiFi to Arduino Boards for $50

You can now add WiFi to Arduino for about $3 thanks to ESP8266, and it’s been long possible to add Ethernet with ENC28J60 module now selling for the same $3. Alternatively, if you want some a little more powerful, you could also use IoT modules running OpenWrt such as a $30 WrtNode or $13 LinkIt Smart 7688 both capable of supporting Ethernet with some hacks. But if you’ve been used to Arduino Yun, have a few spare Arduino boards, or simply think the other solutions are just too cheap, Arduino LLC has just launched Arduino/Genuino Yún Shield for $49.90 / 43.90 Euros. Arduino Yún Shield specifications: SoC – Qualcomm Atheros AR9331 MIPS WiSoC @ 400 MHz System Memory – 64 MB DDR2 Storage – 16 MB flash Connectivity – 10/100 M and 802.11 b/g/n WiFi USB – 1x USB 2.0 host port Board interfacing – SPI and HW Serial Misc […]

How to Run Ubuntu 16.04 Aarch64 (64-bit ARM) Cloud Images on Your Intel/AMD Linux Computer with QEMU

With the recent launch of several low cost Cortex A53 development boards, 64-bit ARM hardware is now pretty common and inexpensive, but if you want to run 64-bit ARM code on your x86 Linux computer, Riku Voipio, a software engineer working for Linaro, wrote some instructions to run Ubuntu 16.04 Aarch64 Cloud image in QEMU. Ubuntu cloud images are “the official Ubuntu images and are pre-installed disk images that have been customized by Ubuntu engineering to run on public clouds that provide Ubuntu Certified Images, Openstack, LXD, and more. ” So the instructions are also useful if you want to easily try such packages on 64-bit ARM platform. I’ve tried those instructions myself on my Ubuntu 14.04 machine with and AMD FX8350 processor, and they worked pretty well, and the only things I had to find out by myself was to install a recent version of qemu. First, we’ll need […]
