Getting weather data from a service [http://blog.kevinhoyt.com/2015/07/29/weather-in-three-flavors/] is all fine and dandy, but in this day and age of IoT (Internet of Things), it almost seems more likely that you will be getting data from sensor in and around your home. In this

In my last post [http://blog.kevinhoyt.com/2015/07/28/bluemix-crawl-runtimes/], I gave an overview of IBM Bluemix, and walked through the process of deploying your web first application. For this post, I will walk through a simple weather application I used to test out some of the Bluemix

Tetris with Virtual Controller

As somebody educated in Information Technology, I have always had an admiration of game developers. Despite the interactive experience and immersive graphics, there is just some black magic in the architecture that leaves me in awe. While I have had my hand at small games in the past, I decided

Android Barcode Scanner

In previous posts I talked about a barcode scanner project. The first post was from a hardware perspective [http://blog.kevinhoyt.com/2015/05/12/first-steps-with-intel-edison/], looking at the Intel Edison. The second post was centered around the software [http://blog.kevinhoyt.com/2015/05/15/real-time-barcode-scanner/] for integrating with

Friday Diversion: Dirty Dishes

The never-ending chore of dishes. (somber pause) What more needs to be said? My daughter actually prefers to clean out the cat liter boxes nightly over having to do dishes. Every now and again you pass the pile accumulating in the sink, and think to yourself that you should put

In a previous post I talked about getting started with Intel Edison, and elaborated a little on a barcode scanner project I used with it. In this post I will discuss the specific architecture and crawl some code. -------------------------------------------------------------------------------- This is reposted on the Kaazing Open Source Blog [http://kaazing.

What is your favorite building? The office? The coffee shop down the street? Your home? Maybe a shed out back? Whatever the case, there is no shortage of ways to augment your home with IoT (Internet of Things). Google Nest, Philips Hue, or WeMo give you classic request/response control

First Steps with Intel Edison

First Steps with Intel Edison

There are a lot of SoC (System on a Chip) devices out there these days. I have written about the Arduino Yun in the past. Today I would like to introduce you to the Intel Edison. At about the quarter of the size of a credit card (35.5mm x

Android Chat Application

In a previous post [http://kaazing.org/blog/java-chat-application/] I discussed using the open source Kaazing Gateway AMQP Java client library. This approach allows us to build a Java desktop chat client running against our free "sandbox" environment. You might be inclined to think that this lets us

If you look around the Kaazing open source web site, you will see a lot of information about delivering real-time solutions on the Web. This is not by accident - we a strong believers in the future of web standards. You can also use Kaazing Gateway with other platforms as

AMQP Breakdown

The open source Kaazing Gateway uses Advanced Message Queueing Protocol (AMQP [http://www.amqp.org/]) to transport your messages from one point to the next. It does this by leveraging the IETF WebSocket [https://tools.ietf.org/html/rfc6455] protocol. The connection from the browser may use the W3C WebSocket

In any given programming language "Hello World" is likely the first thing you will learn to do. The "Hello World" for real-time architectures is a chat application. In this post you will build your very own Web-based chat application. Alternatively, you might also want to check

XBee Mesh Networking

XBee Mesh Networking

As you start working with the Internet of Things, one of the patterns that will emerge pretty early is the concept of serial communication. Initially this takes the form of using something like the Serial Monitor with an Arduino. While this communication happens over a wire, a more practical for

Circuit Friday: DHT22

Last week for Circuit Friday [http://kevinhoyt.com/blog/2014/11/07/circuit-friday-thermistor.html] I introduced temperature sensing with a thermistor - effectively a resistor whose resistance changes based on temperature. We were then able to read the variation of current through the circuit, apply some math, and come up
