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 robotic arms. Somehow I stumbled upon this cool looking open source robotic arm: It was featured on Thingiverse and published by user jjshortcut (Jan-Jaap). ......

.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 if you are using a much cheaper board such as Netduino or one of FEZ family, you are doomed to rely on blinking LEDs only. Not quite so. In most scenarios ......

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 the acrylic pieces there. It is also very easy to build following the instructable (you can find few more photos from my build here). The original SERB ......

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 quite easy. Only care should be taken to ensure that shield can run at 3.3V logic levels (because Arduino runs at 5V). Of course Netduino is much ......

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 library contains most common parts, and you use wires to connect them – exactly the same as you would do on your physical prototype: Next you can switch ......
