In part 1 of the Raspberry Pi Dashcam Series, we talked about how to create a powerful and low-cost embedded computing platform for “always on” live dashboard camera broadcast using the Raspberry Pi 2 Model B and the Raspberry Pi 8MP Camera Module. With this hardware setup, we can broadcast...

We are excited to announce a newly improved AngularJS SDK that offers developers a better experience for building real-time apps. This update adds two abstraction layers that integrate seamlessly with the JavaScript framework: $pubnubChannel and $pubnubChannelGroup....

In April, Arduino launched the new MKR1000 board, a move that I’m sure made countless IoT fanatics, including myself, jump for joy. The MKR1000 integrates the functionalities of the Arduino Uno and a WiFi shield into one neat little two-inch board, making it easier than ever to add all sorts of objects...

Since the Raspberry Pi was released in 2012, the capabilities of low-power, low-cost embedded computing devices have grown tremendously. It is now quite common to see smart devices (thermostats, lighting, locks, cameras) in homes as well as real-time updates in industrial settings such as package delivery...

Did you catch part one of our tutorial where we walk through creating your own bluetooth hardware with Tinyduino? In this article we’ll be continuing from where we left off and completing our bluetooth fitness band. When we last left you we connected your phone to a bluetooth module. Next, we’ll...

This two part tutorial walks you through how you can create your own Bluetooth fitness tracker (think Fitbit) using Arduino and Cordova. You might not have any experience with Arduino or Cordova, but don’t worry! Both technologies are extremely simple and were not even going to wire anything! In...

PubNub is a startup, and like many startups we use a lot of open source software. We are also huge fans of the Raspberry Pi. We’ve even built a Pi workshop because it’s so flexible and easy to get started with. Setting up Raspberry Pis for workshops and projects can be a pain, though, especially...

This article originally appeared over at TechCrunch.  We’re currently witnessing rapidly expanding product launches and sky-high elevated expectations from the emerging deployment of the Internet of Things in both personal and commercial domains. Stakeholders — ranging from hardware manufacturers and...

How many times have you gone around a parking lot more than twice looking for a space for your vehicle? You and I are not alone in this quest. Every time it happens, I keep wondering why there isn’t a smart way to reserve a parking spot in real time and pay automatically when you leave. Until now,...
