Orvibo Wiwo S20 Smart Socket Now Sells for $16

Kankun KK-SP3 used to be the cheapest smart socket on the market at around $20, and it is hackable too, but only available with a Chinese / Australian plug, and for some reasons, many sellers stopped selling the device. Last year, a similar product called Orvibo Wiwo S20 launched with US, UK, EU or AU plug types, but sold for nearly twice as much as KK-SP3 at the time. The good news is that the price has gone down considerably, as it can be purchased for around $16 on GearBest, and it’s available on others for $20 to $26 including on Amazon US, DealExtreme, and GeekBuying. Let’s remind us of the specifications first: Material – ABC 94V-0 (fireproof) Wi-Fi 802.11 b/g/n Security – WEP, WPA-PSK or WPA2-PSK Power Plug – US, Europe, United Kingdom or Australia plug Output Current – 10A Output Power – 2000W max. Voltage Range – 100-240V […]

Snappy Ubuntu Core is an IoT Linux Distribution for ARM and x86

Canonical has announced a version of Ubuntu specifically designed for IoT devices running Linux, with a low hardware requirements, and a new package manager called snappy, replacing apt-get for this version of Ubuntu, which provides simpler, faster, and more reliable updates, stronger security, and allows roll-backs in case something goes wrong. Easy firmware updates are something missing in most connected device, which means they are more vulnerable to potential hackers, but with snappy security updates should be able to make it regularly, so that if something like heartbleed occurs again, you know your router, home automation gateway, connected washing machine, or robot will be soon patched automatically. Let’s go through the hardware requirements first: Processor – 600 MHz processor (ARMv7 or greater, or x86) System Memory – 128 MB RAM or greater (The system itself uses 40 MB RAM) Storage – 4GB flash / storage for factory reset and system […]

Ninja Sphere Home Automation and Monitoring Platform

Ninja Blocks is an company providing open source hardware solutions for home automation. Their first product was called Ninja Blocks Kit which includes a Ninja Block (Beaglebone + Arduino based gateway, but they now also support the Raspberry Pi), sensors, sockets, cables, and a power supply, and works with Ninja Platform, an open source software framework. The goal was to simplify the process of developing automation applications by taking care of all low levels tasks such as electronics, embedded programming, network protocols.., and letting “end users” / developers focus on their application. The company is now working on a new version called the Ninja Sphere, including a “Spheramid” gateway, location waypoints (Bluetooth low energy tags), and smart power sockets. Here are the key features of the gateway: Processor – ARM Cortex A8 (probably Texas Instruments Sitara) Color LED Matrix Connectivity – Bluetooth, Bluetooth LE, Zigbee, and Wi-Fi USB Port – […]

Ninja Pi Crust Let You Connect Arduino Shields to the Raspberry Pi

There are quite a few projects using both the Raspberry Pi and an Arduino board and its shields together. These are working but the cabling may get messy. People have already found solutions to plug Arduino shields into the Raspberry Pi with products such as Cooking Hacks’ Raspberry Pi to Arduino shield connection bridge (40 Euros) or Open Electronics’ Raspberry Pi bridge (22.50 Euros). Those two boards are fine, but do not include an Atmel MCU, and use Raspberry Pi GPIOs directly, except for their ADC. Another solution is the Paperduino Pi, a DIY Arduino board that can be plugged on top of the Raspberry Pi, and compatible with Arduino shields. But if you want an Arduino board that can easily be stacked between the Raspberry Pi, and Raspberry shield, the upcoming Ninja Pi Crust by Ninjablocks may be an interesting option, especially if you plan to use the 433MHz […]
