This is pure awesomeness!!!

The IoT (Internet of Things :P) space is getting pretty interesting. Eclipse (one of my fav IDEs) has now released a powerful IoT stack for Java developers to build awesome IoT applications.
Check out more details here: http://iot.eclipse.org/java/
This is getting interesting 🙂 I need to try out a demo… Hey, they even have a live demo page setup here that’s playing with the Raspberry Pi: http://iot.eclipse.org/demo/#/devices/%23
Happy IoTing 😛
Came across this interesting (and minimal) Raspberry Pi project on Makezine:
This is pretty interesting as all you now need to have a broadcast FM channel is a Pi and a Wire 😉
Note: Unauthorized sending of signals over FM bands is restricted and also a punishable offense in some countries. I take no responsibility whatsoever.
The world of wearables is taking the world by storm. Android Wear, iWatch, Smartbands, Leychal (Smartshoes, proudly made in Hyderabad, India), etc.
And here’s the many sensors found in a generic Smartphone:
Imagine if you could grab all those data using off the shelf devices?
Symantec wrote a nice post about how insecure these new wearables are and how they can be snooped into.

Instructions for getting started can be found on his github repository.
I’ll try this out myself and hopefully let you guys know how it goes! This is super exciting for me 🙂
[tag Raspberry Pi, Android]
This is little old though and something similar to WebIOPi, but it’s growing steadily and the features packed in are a treat for Pi and HW enthusiasts.
Check out BerryIO here: https://github.com/NeonHorizon/berryio
Just including one screenshot 🙂
Came across this awesome interactive pin mapping for the Raspberry Pi. This also includes some expander boards.
If the above frame doesn’t work, use this direct link:
If you followed our previous post (Direct SSH into Raspberry Pi in Headless Mode), you must have noticed that we were not able to get the lxpanel (the Start menu bar) of the Raspberry Pi and only the desktop was streamed. We had this tweak that solved the problem.
Once successfully SSHed into the Pi, run this command lxpanel instead of lxsession or startlxde. That will pull up only the lxpanel in the bottom as shown below:
Now, click the terminal icon (3rd from left) from the Pi’s taskbar and another terminal window should pop open. Now, inside this, enter the command lxsession or startlxde and you should now be able to see the Pi’s desktop.
I was struggling for some weeks getting this done, but just achieved a breakthrough. This post will brief out controlling the RasPi’s GPIOs over the network and demonstrating how easily it can be used as a powerful IOT device. Most of the details including the WebIOPi framework, libraries and scripts are taken from https://code.google.com/p/webiopi/wiki/INSTALL.
First and foremost, download the WebIOPi framework from the Raspberry Pi’s terminal by typing in the following commands
$ wget http://webiopi.googlecode.com/files/WebIOPi-0.6.0.tar.gz $ tar xvzf WebIOPi-0.6.0.tar.gz $ cd WebIOPi-0.6.0 $ sudo ./setup.sh
The setup script will automatically download the required dependencies and headers for Python which are almost 35-40 MB in size. It took me almost 60 mins as I’m currently on a very very slow network 🙁
Once all the packages and dependencies are installed and deployed, you should see this success message:
Now, simply shoot this command in the terminal:
sudo webiopi 8000
and Voila!!! You should see framework messages like this:
Now, open your browser on the same Network. If your RasPi is plugged into a display unit and you’re using a Mouse/KB plugged to the Pi, open midori and type this in the address bar:
where 169.254.39.71 is the IP addr of the Raspberry Pi and 8000 is the port you just defined previously. Since I’m connected on the same WiFi network, I typed addr this into my Laptops’s Chrome browser and this is what we get initially:
Click the GPIO Header link and you should see something like this:
Now connect a small LED to GPIO4 (7), change the Pin direction to OUT from IN and toggle the value by clicking on 7. You should see your LED also blink 🙂
You can see a quick demo here:
