Working with OpenCV and Processing under linux

Just a tip for everyone having trouble when working with the OpenCV library for Processing.

After installing OpenCV in a recent Ubuntu distro, following the instructions, you might get an error like:

UnsatisfiedLinkError: hypermedia.video.OpenCV.capture(III) ...

When you try to execute the Opencv library examples in Processing.

The solution is easy...

Drawing frames

Audiovisual installation in which the robotic arm of "Random" draw the silhouettes from the captured frames of a video camera.

Android meets with arduino

Early tests to communicate Android with Arduino to control servos.
Establishing wireless communication using the OSC protocol sends data from mobile sensors by pduino to pure data that communicates with Arduino to control the servo.

The Drawing Robot sketching a smiley

We are currently testing the possibilities of a robot arm we built. As it is a prototype, the accuracy still needs to be improved.

The key of the arm design is to translate the weight of the motors as next as possible to the base, in order to lighten the arm, thereby reducing the inertia and the stress of the motors.

Realtime mapping video projection experiments

Early experiments to realtime mapping video projection over a physical object in movement.

The robotic arm interacts with sound

TheRandomLab experiments presented publicly during IN-BETWEEN project in Delphi, Greece.

Axiomtek PicoITX embedded board - making an enclosure case

We found a good deal in ebay and bought an Axiomtek Pico820 board to use it for robotics projects. This board is a full Atom PC  with 5W power consumption at 5v.

Random has brain & wheels

Random, our pet, already have brain and motorized wheelchairs. We used the RCX 2.0 & Lego bricks.

CrazyLetters

For the day of the book we had the opportunity to test some open source multitouch installation, powered by Nuigroup's open software.

Portable P48 microphone preamplifier

Once every while, I like to have a look at second hand shops searching for any nice deal. In one of these visitsI bought a Sennheiser MKH-416 P48 professional shot gun microphone for 275€. But then I had the problem of how to interface it to my videocamera.
