This is my work so far. The construction of the box (80x80x80cm) itself is done. I’ll add some eye-candy (color, lights, etc.) later on. The plexiglas is 10mm thick and completely transparent. Right now I’m waiting for the “lee density frost” diffuser surface, wich will be mounted beneath the plexiglas as a projection surface (and to spread the IR evenly).
I soldered the IR leds to a circuit board and hooked them to a pc power supply (12V). The tracking device is a Sony DCR TRV digital 8 camcorder with nightshot. It’s connected through firewire and will get a wide-angle (0.4x) and just to make sure an IR filter. Its DV resolution and the high FPS will give me some good results in the tracking.
The beamer uses a wide-angle lens, too… but probably still needs to be aligned with a mirror to get the proper image size on top.


WHAT I AM DOING NOW: Testing different frameworks (reacTIVision, CCV, touchlib) to get the best results in blobdetection. Building stands for the IR spots, camera, beamer etc… setup hardware.

basic thoughts and MOCKUP, running with win7 and ccv



Jena9D

Dirk Schwittlich and I came up with this idea for an analytical mockup of Jena (Germany).
It’s a physical mockup made out of Styrodur showing the historical change of the city’s structure, layer by layer.
Additionally we light up certain areas of the mockup following a timeline, giving the audience a grasp on how the city changed over the last century.
Along with that, pictures and videos are displayed next to the mockup, each corresponding to historic events that provoked these changes.

We were able to overcome certain shortages of the architectural mockup by adding a new dimension, the time. Creating a unique dynamic visual experience without making the mockup unreadable when the animation is not present.

This was the second attempt with more to follow. Thoughts for the future are:
Adding a user interface, so the audience decides what information they want to display.
Being able to display elevations, etc. on top of the mockup houses.
Using more than one beamer to display information on the vertical faces of the mockup.

Diese woche sind bei uns im mr 2 neue kleinere projekte entstanden.

Das erste ist eine Unterbodenbeleuchtung für einen Tisch. Vier kaltlicht-kathoden und ein netzteil wurden per kabelbinder an den Tisch gespackst.  löten, bohren, kabelbinder, kurzschließen und fertig wars.




































Im zweiten projekt haben wir ein netzteil so umgebaut, dass wir spannungen zwischen 3V und 24V durch unterschiedliche anordnung von kabeln erreichen können. somit haben wir ein arbeitsgerät mehr im mr.

löcher bohren, löten, abschneiden und abisolieren, verbraucher (momentan in form einer alten festplatte) dran damit das NT anspringt, kurzschließen, fertig

we just went NUTS

We just went crazy with an old and basic synthesizer and the Electro-Harmonix Stereo Memory Man. We came up with some really weird sounding stuff. This recording is all live, there was no digital editing done to it afterwards. Although it could really use some drumlines ;)

Der code vom ehemaligen twittdoor script wurde neu geschrieben.
Mehr dazu von Ed via maschinenraum:

“Ich hab mich dann doch ‘heut’ mal hingesetzt und eine komplett neue Version von dem Script gebaut was cron dazu bewegt den Status der Tür auf Twitter veröffentlichen zu lassen. Aus mangelnden C-Kenntnissen und Konzeptkritik der alten Version hab ich das einfach mal in PHP hingehackt und was ich so getestet hab, läuft das auch echt knorke.

Der Status der Tür wird mit dem auf Twitter abgeglichen und dabei muss nur innerhalb der letzten 10 Tweets was über den Status stehen. Denn die Tür soll ja in den nächsten Versionen auch Kommentare oder ähnliches von sich geben können. Naja what ever. Der Source steht unter einer WTFPL und wem weitere Zweckentfremdungen einfallen kann ja bitte einen Kommentar, Trackback, Ping, … da lassen.

Den Source gibt’s hier.”

Danke Ed!!!

There are several people not having a key to the “MaschinenRaum” and they don’t wanna get out of bed just for standing in front of a locked door. So we decided to let the door tweet whether it’s locked or not.

We started with a LPT cable that is connected to the parallel port on our server.
On the other end there is a switch inside the door that is pressed by the bolt as soon as the door is locked. When the button is pressed, pin 10 of the LPT cable which usually carries 4.5V  is grounded. We can now monitor this state of change with a tool called “pin” provided by the “parashell” package and send out a tweet with the help of  a cron job and “blt“.

You can follow our door here.
