5 Smart Devices That You Can Make At Home With Arduino

The curiosity of the human being has no limits and, within it, robotics is one of those fascinations so unique that they are able to mobilize thousands of people to test their limits and develop home applications. On this road to ‘amateur’ robotics, there has been a lot to do with the irruption of open hardware: simply programmable boards that could be connected to all kinds of sensors to perform the most unexpected actions.

One of the most popular and used boards in the world is Arduino. It is a really simple device (a printed circuit board with a microcontroller, input and output ports and USB connections, through which it is also powered) that was first launched in 2005 and it can be used to develop all kinds of applications. Sensors of temperature, light, proximity, movement, infrared, etc…

Mass provisioning of Kismet and Apache MiNiFi in Raspberry Pi using Ansible


Holistic Security and Technology

Lately I’m focusing on Automation in Big-Data Projects, and with my experience in Cyber Security I can bring new approaches and ideas to those Big-Data Projects are related to IT Security aspects (Threat Analisys, Privacy, Intrusion Detection, etc.).
With this post I will start a serie of articles explaining how to do “Data Ingestion/Capture” in the Edge by using:

  • Ansible to provisioning.
  • Multiple and remote devices in the Edge (Raspberry Pi).
  • Kismet to capture WIFI Anonymous traffic in the Edge.
  • Apache MiNiFi to enrich and route the captured traffic in the Edge.
  • Apache NiFi to collect the enriched traffic and forward to Solr / ElasticSearch.

…everything, near to real-time ;)

And if you want to explore in deep other use cases, this article is a must read: (EDGE INTELLIGENCE FOR IOT WITH APACHE MINIFI)[https://hortonworks.com/blog/edge-intelligence-iot-apache-minifi/]

In short, I will explain in this post the following:
– Manage several…

My Experiment with Raspberry Pi 3


I recently bought a Raspberry Pi 3 to perform simple experiment. Experiment is to try flashing Android Internet of Things(IOT) on it and run sample app.

ThingsUsed

  • Raspberry Pi3, Model B, 1GB RAM
  • MicroSdCard 8Gb
  • Latest preview image from Android of things
  • Instructions on copying the image to SDCardusing Mac here
  • Instructions on using the image on Raspberry PI here
  • HDMI cable connected to monitor, microUsb acting as power supply, ethernet cable for internet and mouse.

20161222_085324Experiment’s steps overview

  • Downloaded the preview image from the android of things and copied it in microSdCard from the instructions above.
~/Downloads|⇒ sudo dd bs=1m if=iot_rpi3.img of=/dev/rdisk2

Raspberry Pi Zero W review


AIVAnet

Buy now from Amazon

The Raspberry Pi Foundation recently launched the Raspberry Pi Zero W, an improved version of the original Raspberry Pi Zero that adds built-in Wi-Fi and Bluetooth. These have been two features many Raspberry Pi fans have been requesting for a long time, and now, thankfully, they’re finally built into the wonderful Raspberry Pi Zero.

  • Raspberry Pi Zero review
  • Raspberry Pi 3 review

Since the Raspberry Pi Zero W is simply a variant of the Raspberry Pi Zero, this isn’t going to be a full, in-depth review. Instead this review will focus on all the new features the Zero W brings to the table. If you’re looking for detailed performance metrics on this board, I’d suggest heading over to my original Raspberry Pi Zero review. It’s also worth reading my review of the Raspberry Pi 3 as it was the first Raspberry Pi to feature built-in Wi-Fi and Bluetooth.

Streaming data from the ST Micro SensorTile to Azure


Kevin Saye

Recently, I had an opportunity to dive into ST Micros’ ultra small Sensor Tile — 13 mm by 13 mm.  If you have not had an opportunity to work with them, you can get one here: http://www.st.com/en/evaluation-tools/steval-stlkt01v1.html

As you can see below, comparing the Sensor Tile (top right) to the NodeMCU or Pi Zero, tells you the size we are talking about.

20170508_105822

One of my customers wanted to track movement using 2 sensors, to compare and contrast and calculate differences between the two.

These little sensors really perform, and as such we had to perform edge summarization.  Each sensor produced over 100 movements per second — clearly creating, at scale, a bandwidth (and cost) concern.

To address this need, and working with ST Micro, I have connected 2 SensorTiles (via Bluetooth LE) to a third, which is connected to a Raspberry Pi Zero (via Serial).  The PI takes the serial…

Two days with Raspberry Pi | IoT Workshop


Aditi Acharya

Internet of Things ‘IoT’ is currently the hottest topic. It is simply an immense network of connected things.  It is all about creating the digital representation of the real world entity. Talking about Raspberry Pi, it is an ARM-based small circuit board computer with the intention of providing low-cost computers and foster computer science education. Right now it has been popularized by the makers of IoT devices.

Windows 10 IoT Core


Andy's TedNet

They said it is an exciting time for developers.

I picked up a Raspberry Pi 3 and a Starter Pack for Windows 10 IoT Core for Raspberry Pi 3. Time to brush up my programming skills.

For those wondering what is IoT, it stands for Internet of Things.

I share more when I start working on it. For now I just want to show you the stuffs.
