Welcome to Linz

Ars07

At the moment there is the Ars Electonica Festival in Linz Austria and we are very proud to be able to show our project at the Campus 2.0.

You can find us at the Kunstuniversität Linz on the second floor.

We have some more pictures of ways to use natebu in public:

More Power

August 16, 2007

PowerSupp

Until now we used to power the matrix over the USB ports of three computers. This was no satisfying solution at all. We now connected an old computer power supply which has a 5 V DC output. This does the job just fine.
We also did some work on the code. We now have a mode to display text and abstract animations.

Arduino Code

We finally can show you some arduino source-code of our project.
It is  quite a mess and really rough but it seems to work.
We are working on a more sophisticated version so stay tuned.

Three days and nights to go

We are getting awfully close to the finishing line…

Getting it to work

pcb_matrix1

Today we assembled the first pcd matrix board. It took about 4 hours but doesn’t it look great? To our surprise it also works great. We are quiet relieved to see that the calculations and the planing war right. We will upload a video as soon as possible.

Montage

Probably the worst photoshop montage ever 😉

Monolith Montage

We go in production!

PCD Layout

Dude to the complexity of our pcb layout we where looking for some help. Iftest a company for  Innovative Industrial and Medical Electronics offered us some support and today we received the so called “gerber daten” for the boards. We are already looking forward to get out our soldering irons 😉board_layout

Video demonstration

May 26, 2007

This is a short video demonstration of how our matrix prototype works:

Fake it till you make it

May 22, 2007

Today we set up a new test installation. We used a video projector, a rear projection screen and the infrared webcam to simulate a large scale interactive led matrix. It only took some lines of processing code and about 1200 small reflective strickers.

Thanks to all the fellow student who helped with a cople of stickers 😉

This picture is a screenshot from processing:

Circuit Diagram

May 21, 2007

This is our attempt to draw a circuit diagram of the LED units.
We are not quite sure if it is a good solution, but is works one the prototype.

It Works!

May 20, 2007

After sorting out some soldering mistakes and after debugging our Arduino code the prototype finally works.

the prototype

One smaller problem we still have, is that the Arduino can’t give us as much power as we would need. But this can be solved easaly with an additional power supply.

For the moment the capacity of the matrix is still kind of limited. All it can to is light up LEDs whenever the infrared transistors get enough light. Any object that gets close enough to a transistor will trigger the accordant LED.

With some more programming we will be able to do much more.

The first prototype

May 10, 2007

Some pictures of our first interactive matrix prototype.

Our prototype consists of a matrix of 64 dots.
Each pot has one LED for the output and one infrared fototransistor with an infrared LED as input. To control all this we use the Arduino beard.

Fot this first prototype we decidet to use wires instead of the conductive ink.
It turned out to be a lot of soldering work…

Multi Touch with FTIR

You may already know Jeff Han and his multi touch finger tracking, if you don’t go here: http://cs.nyu.edu/~jhan/. With a small acrylic pane, some IR LEDs a video projector and a webcam that we modified to see IR light we built our own little multi touch display. It actually works really well.

This is a picture from the IR webcam. The bright spots is where the fingers touch the acrylic pane.

Make a PCB

April 16, 2007

pcb_firsttry_web.jpg

After the burdensome trip to Mr. Mathis lab we could start to bulid our first PCB. Draw some conducting paths on a self-adhesive foil and cut them out. Put the stencil on a nonconducting surface and spray it with Mr. Mathis paint. Remove the stencil carfuly and add some LED’s to it to make sure that it works. More pictures after the jump.

Technology Partner Meeting

April 12, 2007

farb_rob_web.jpgToday we went for a trip to Luzern. After a short stop at the Museum of Art and a lake-side picnic we had a meeting with Roger Mathis from http://www.sansecura.ch/ a company for electromagnetic field shielding. With a lot of useful information and a bucket full of a highly conductive paint we took the train back home. You may see in rob’s face that we cant wait to test it ;- )

Research

April 11, 2007

recherche_web.jpg

We spent the week doing some research. We were searching for all kind of projects in art, design, architecture, programming and technology and we found a lot.
We bookmarked most of the things we found on our delicious_pic.png del.icio.us page.

Timetable

April 2, 2007

timetable

We are proude to present you the first step on the long road to our diploma. The timetable! A very useful tool to get your final degree. We are the world’s first transdisciplinary team who trys to addresse the relationships between a art project and a timetable.

Hello world!

April 2, 2007

So, here we are!

Natebu is a documentary blog of the diploma project of André Huber and Roland Broennimann.
We are students at the University of Applied Sciences Northwestern Switzerland www.fhnw.ch Academy of Art and Design. André in Industrial Design and Roland in Media Arts.
On this blog you can follow our Project for the next couple of months.
