Szymon Kobalczyk's Blog A Developer's Notebook
This is first in series of articles about project I've been building in my spare time since last Summer. Actually it all began when I was researching a topic of modeling human motion kinematics in order to create gesture recognition library for Kinect. This ties heavily into motion theory of robotic manipulators so I also glanced at some designs of ......

Last week I had a pleasure to speak at the Microsoft’s Developer Days 2012 in Sophia, Bulgaria. It was a great conference and I met lots of cool people there. I did a session about Kinect Hacking. My goal was to give a good understanding of Kinect inner workings, how it can be used to develop Windows applications. Later I showed examples of interesting ......

.NET Micro Framework includes reach graphics capabilities with WPF-like libraries, and quite a few high end development boards (Tahoe II, ChipworkX, or FEZ Cobra to name a few) include fancy graphic TFT screens, often with touch input thrown in as well. But this comes at a significantly higher costs, and requires a speedy CPU. Thus it might seem that ......

For my next project I decided to try to upgrade my SERB robot that I showed here last year to use Netduino. This robot was designed by great inventors from oomlout and you can buy it as a nicely packaged kit from them. However because the design is open source you can also download the project files and if you have access to a laser cutter order all ......

Some time ago I wrote about FEZ Mini and FEZ Domino – first affordable development boards for .NET Micro Framework. Today I’m excited to tell you about another device called Netduino. Similar to FEZ Domino this board is pin compatible with Arduino, and therefore most of Arduino shields should work fine on Netduino. This makes transitioning your project ......

After seeing that some of my friends get fancy customized pictures for their Facebook and Twitter profiles I thought it would be cool to get one too. But not for me – for my wife. You see, she currently works as IT Security Officer (the best I know btw.) but earlier when she started as security auditor and she worked as part of the “tiger team”, she ......

Yesterday I picked up a nice package from TinyCLR.com. Yes, it is yet another robot (third in fact), but this time it runs .NET! How freaking cool is that! This robot is controlled by FEZ Mini board that runs .NET Micro Framework. What’s interesting is that this board has pin-out compatible with Basic Stamp from Parallax. You can also uses it easily ......

Just after finishing my multicolor RGB controller shield for Arduino, I came across Fritzing, a program that lets you convert your breadboard prototypes into a physical PCB. Since I got one design working at hand, I decided to give it a try. The process is very straightforward. First you simply put all the components in the breadboard view. The parts ......

For me one of the coolest new features added in Silverlight 4 is support for capturing video and audio using webcams and microphone. As we’ve seen during Scott Guthrie’s keynote demonstration it is now possible to capture image frames from video stream and apply some interesting effects to it. On top of that we can even process the video and audio streams ......

I’ve came across this interesting thread on Arduino forum about using IKEA DIODER and other RGB LED strips to build mood/ambient light. This allows you to create the same effect that you can now find on some TVs. I thought it would be a fun little project to do, and here is a short clip to show you the result: In case you would like to build it yourself ......
