Wiimote Sensor bar build up stage1

At this moment I'm at the stage of building a Wiimote IR sensor that will be attached to the goggles in order to co-operate with Wiimote's camera. I have already purchased LEDs needed.

And here is the tutorial how to build the sensor bar. 

My feelings and expectations towards the project are very pessimistic at this moment because I have a problem with the goggles. They seem to be broken unfortunately:( Only one screen is working and the other one is not responding/is off. I will carry on with the next stage as I planned but the final effect will be far cry from expected. After the sensor bar is done, the next stage will include the servo motor movement adjustments. Wish me luck!

Happy New Year!!!

Wiimote sensor bar

Well, you may ask why oh why did I put this video here... It is funny and to the point. I have been installing my Max/MSP Jitter and Arduino back again after it has been not present in my computer for long few months. After a while, whne everything was there, I was testing my patch and everything that goes with it: cameras, Wiimote, goggles and Arduino. The first camera appears to be broken...hmm, it should not be a big problem, it cost me only 5 pounds to get a new one. The second camera that is inside the goggles seems to show a blurry picture so few more adjustmesnts need to be done. Next, the Wiimote is not detecting the IR LEDs of the camera inside the goggles even though the LEDs stick outside the goggles cover. I have spent 6 hours today trying to figure out what is the problem. The funniest part, that also relates to the video, is the Wiimote detecting my ceiling lamp like if it was a IR LEDs. Hah, so much to be done tomorrow. If the bug won't be fixed quick, the option would be to build a Wiimote sensor bar. Simple and convenient.

Ortho-goggles revisited

Hello everyone! The project which I have been describing in details on these pages entered the next stage of development. Already, there have been improvements in esthetic's design. The camera placed on the goggles, responsible for showing the surrounding, has been mounted inside the goggles. Moreover, some additional features have been added to the overall look of the davice itself. The cover has been taken off in order to fit the camera and so the new cover had to be developed. Plus, previously it's been proved that the visitors of TVU Degree Show Digital Piracy Exhibition weren't convinced by its fragile structure. Today, the structure is more stable and user friendly. 

   A device that I am creating is a digital tool for artists. Its form is way much more sophisticated than a brush or pencil but also in terms of usability it is also more valuable. This device allows us to manipulate the perspective of the image. It becomes a tool for an artist in terms of vision and imagination. Additionally, it represents the technique of projecting a fully dimensional 3D object onto 2D plane, a technique called isometric projection. It is a method of representing three-dimensional objects in two dimensions where the X,Y and Z axes are equally foreshortened and and the angle between any two of the axes are 120 degrees.

The project consists if two cameras, AV goggles, two RC hobby motors, Wiimote controller and a projection plane. The first camera is attached to the goggles and the second to RC motors. The position of the first camera depends on the position of the second. Both move along X and Y axis thanks to the Wiimote controller placed under the projection plane. The Wiimote controller's role is to be a vantage point and to read the position of an object in 2D or 3D space. In this case it is the position of the first camera in 2D space that is being read. Thanks to these specific values of the controller, it is possible to send the data of a position of an object to be received by RC motors that control the position of the second object. And so, the position of the first camera is equal to the position of the second camera.
