I’ve previously covered several Chinese Wi-Fi smart sockets including Broadlink SP2 also supporting power monitoring, and Kankun KK-SP3, a cheaper, more basic version that can only be turned on and off manually or via timers, and which runs OpenWRT. These plugs have one thing in common: they only come with Australian/Chinese plugs, so if you want to use them in Europe, the US, or United Kingdom, you’ll need an adapter, which may not the the safest things to do, and it’s also inconvenient. Orvibo Wiwo S20 is another model that appears to have the capabilities and a price similar to Broadlink SP2, but available in four flavors with US, EU, UK, and AU plug types. Orvibo Wiwo S20 is made of fireproof ABS, and is significantly smaller than Broadlink SP2, but the rest of the specifications are very similar: Material – ABC 94V-0 (fireproof) Wi-Fi 802.11 b/g/n Security – WEP, […]
Kankun KK-SP3 Wi-Fi Smart Socket Hacked, Based on Atheros AR9331, Running OpenWRT
Kankun KK-SP3 is a $20 Wi-Fi smart socket that can be controlled via iOS and Android app. But one person created a Kankun community on Google+ to try to hack the device and control it from a PC, or from outside the home network for example. Up to now, the device has been opened, found to run OpenWRT, and one the member wrote a Windows app to control the socket from a PC. It is a basic smart socket, without power monitoring capabilities, and unless you start hacking the hardware, all you can do is basically turn it on and off. The device is based on Qualcomm Atheros AR9931, found in many low cost routers supporting OpenWRT, and the socket indeed runs OpenWRT, which you can access via SSH or Telnet (username/password: root/admin). There’s 32MB RAM (Winbond W9425G6JH), and a 10A OMRON relay. The smart socket actually communicates with the […]
Immedia Blink Battery Powered HD Security Camera Lasts Over One Year on Batteries (Crowdfunding)
There are plenty of security systems with IP cameras selling on the market, but they can be a pain to install because you need to use long power cables or use power extensions. There are battery-free such as NETGEAR VueZone Home Video Monitoring System that cost $259 with 6-month battery life for normal usage, and $50 yearly subscription fee. Immedia Semi is providing an alternative with Blink, a wire-free (wireless + battery) HD Home Monitoring & Alert System that starts at $69 with one camera, and is said to last over one year powered by two CR123 batteries, without monthly fees, and can stream live views and video recordings to your Android or iOS smartphone or tablet, or any web browser. The one-year battery claim seems preposterous. How is that possible? The first reason it’s possible is because of the way typical usage is defined for home security cameras. They […]
Thread is a New IP-based Wireless Protocol Leveraging 6LoWPAN and 802.15.4 Standards
Wi-Fi is a neat way to connect devices to Internet, but it has two main inconveniences: relatively high cost and power consumption. Luckily there are standards that addresses the cost and power consumption issues. Radio chips based on IEEE 802.15.4, a standard which specifies the physical layer and media access control for low-rate wireless personal area networks, are common place and found in many existing devices relying on higher level wireless protocols such as ZigBee, ISA100.11a, WirelessHART, and MiWi. AFAIK, Zigbee is the most popular of the aforementioned protocols, but is hindered by the requirements of the license for commercial products (annual fee), Zigbee membership requirements conflict with many open source license such as GPL, and the standard suffers from lack of interoperability and IPv6 support, and power requirements that are too high for some applications. So a consortium of seven companies namely ARM, Big Ass Fans, Freescale, Nest, Samsung, […]
Forlinx OK335xS-II is a Low Cost Linux and Wince Industrial Board Powered by TI Sitara AM335x Processor
Forlinx Embedded, a company based in Baoding, Hebei, China specializing in embedded systems design and manufacturing, has recently launched OK335xS-II single board computer powered by Texas Instruments AM335x SoC which they claim to be “the cheapest industrial Cortex-A8 board in history” as it sells for as low as 298 RMB or about $48. OK335xS-II board is comprised of a baseboard and a CPU module soldered to the carrier board with the following specifications: SoC – Texas Instruments AM335X ARM Cortex-A8 processor @ 800MHz with PowerVR SGX530 GPU System Memory – 128M DDR3 + micro SD slot Storage – 256MB SLC NAND Flash Display I/F – LCD interface with support for LCD to LVDS and LCD to VGA, and resistive touchscreen interface Connectivity – 1x 100M Ethernet USB – 1x USB 2.0 host, 1x mini USB 2.0 device Serial – 5x serial port (1x debug interface, 4x TTL port) Expansions headers […]
Peek into the Smart Home of the Future with ARM Seamless Computing IoT Demo
We’ve seen lots of home automation being launched on crowdfunding platforms in the last year or so, and companies like Samsung, Archos, Google and Apple have launched, announced, or bought smart hone solutions. Recently ARM has hosted a demo for the smart home based on Cortex-M MCU mbed development boards, a single board computer gateway, and sensinode connected home software framework. Although some parts of the demo are unlikely to really have uses, e.g. you can look at the window to check the weather, I found the demo to be very interesting, especially with regards to the central role of the smartphone, and computing convergence. The list of different demos that can be seen in the video below is as follows: As you walk close to the main door, the system checks the weather, and if it rains, blinks a LED and emits a sound close to your umbrella, and […]
Texas Instruments Announces Sitara AM437x Cortex A9 SoCs and Evaluation Modules
The first time I heard about Texas Instruments Sitara AM437x was via a TechNexion EDM-CT-AM437x system-on-module back in 2012, but Texas Instruments Sitara Cortex A9 processors development seems to have dragged a little longer than expected. Nevertheless, the company has now formally announced their Sitara AM437x ARM Cortex A9 SoC targeting automation, IoT gateways, and other industrial applications, and featuring four PRUs (Programmable Real-time Units), and support for dual camera for terminals with bar code scanning. At launch there will be four AM437xprocessors: AM4376, AM4377, AM4378, and AM4379. The processors will all be based on a single Cortex A9 core @ 800 to 1000 MHz with 64KB SRAM shared with 32KB data cache and 32KB programmable cache, 256 KB L2 and L3 caches, a 32-bit memory interface supporting LPDDR2, DDR3, and DDR3L, a 2-port Gigabit Ethernet switch , two USB 2.0 OTG + PHY and the following other interfaces: Serial Ports […]
Review of Broadlink SP2 Wi-Fi Smart Plug
I have received Broadlink SP2 Wi-Fi smart socket for Android and iOS thanks to GearBest, a Chinese e-retailer, that was kind enough to send a sample for review. I’ll start by showing some pictures of the package and device, and report the results of my review with an Android phone (ThL W200). Broadlink SP2 Unboxing Pictures The company send me the parcel via DHL, and I received in the package below, the top with the picture, and the bottom with specifications in Chinese. There’s only the smart plug in the package. The top is a universal plug, but the bottom is a Australian/ Chinese plug, so most people would need a wall adapter. It support 110 to 240V AC up to 10 amperes, consumes less than 0.5W without load, and it designed to handle 50,000 on/off events. The thing that surprised me was the size of the plug at first, […]
