Hello all!

Some time ago I visited this forum and took lots of doubts regarding an ongoing experimental project. I would like to post the results of this work bellow:

Nama, my graduation project on design/art/technology. A study about contemporary aspects of language and the sensitization of movement in search of a personal unique creative pulse.

http://viraseres.com/nama/

Videos:

Interactive Installation:

http://vimeo.com/viraseres/nama

Experimental interface for movement:

http://vimeo.com/viraseres/nama-instrument

The full concept and development documentation is available at the website, together with a DIY tutorial of the interface, and the open source files of the generative audiovisual installation.

Feel free to send me feedback, critics and opinions.

Thank you all for your help!

Processing + Bluetooth + Arduino - Major problem! Please help!

Hi!

I've also posted this question at http://arduino.cc/forum/index.php/topic,106839.msg801657.html , and several other forums, yet with no answer!

I'm developing an audiovisual installation, that uses data from a soft circuit (Lilypad+accelerometers+bluetooth mate silver) to generate images and sounds on Processing. More info and codes: http://namainstrument.tumblr.com. This is really a major problem that can inviabilize the whole project if not solved.

My problem is that everytime the power supply connection of Lilypad (or even the bluetooth itself) fails for any reason, even for a very little time ("blinking" the power), bluetooth simply looses its connection to OSX (and consequentially, to Processing, or even Arduino's software serial port!).

So everytime this happens, I have to close Processing, click on System Preferences>Bluetooth>Edit Serials ( http://www.quando.art.br/transfer/screen-problem-bluetooth.png) and just them, after a while, OSX recognizes the signal, and I can re-open Processing and start communicating again!

Does anyone knows a workaround for this?

Is this occasioned by a misfunctioning of any of my devices, or perhaps a misconfiguration of them?

Is it possible to perhaps avoid this on Processing itself?

Thanks a lot!

Set 3 viewports from 3 camera()s pointing the same object ?

Hi!

I'm developing a sketch with toxiclibs and verlet physics, modeling 3d visuals.

I'd like to know if it's possible (or if there is a contributed library that would help) to display 3 views from 3 cameras pointing the same "object"?

I've done this example by screenshotting my sketch and gluing them on photoshop to show you what I mean:

[toxiclibs] Verlet Springs - setRestLength ?

Hi!

I'd like to know what exactly is the difference between setting the "rest length" when first creating the spring, and changing it afterwards on draw().

Even when I pass the same values (at the beginning of the creation, and afterwards on the draw() loop), the system just seems to go crazy/chaotic!

Is there a way of avoiding this, or I am missing an important physics concept here? Does anybody knows about this?

Thanks a lot!

Hi!

I've been trying to run the following code: http://www.openprocessing.org/sketch/23110

And keep receiving the message "The type GravityBehavior is ambiguous", and the code just do not compile.

Does anyone knows a workaround for this?

Thanks!

Bluetooth Mate Silver + Processing - Mac pairing problem

Hi!

I'm developing this interface: http://namainstrument.tumblr.com that uses LilyPad Arduino with Bluetooth Mate Silver.

I'm having a big trouble trying to make its pairing automatic on MacOSx.

Everytime I turn Lilypad on, i have to paire it through the System Preferences.

This is a problem since - being a malleable interface - it is possible (inspite of unlikely) that Lilypad turns on/off quickly. By doing so, I completly loose bluetooth's signal, and have to do de whole protocol all over again.

Is it possible to configure it to paire automatically? Would this solve this issue I've pointed?

Thank you!

#00 - Cellular Automata - Vichniac + Cultures adapted

http://www.openprocessing.org/sketch/59527

Cellular Automata (Gerard Vichniac Voting Rule). Class based on Matt Pearson's code as seen on the book "Generative Art", and modified by me to add different cultures inside of macro-cells, as well as some new features.

This is still an experimental work in progress. It is part of the back-end generative system of another ongoing project (http://namainstrument.tumblr.com), that will generate audiovisual feedback according to changes at this system through an interface.

Contributions of opinions and enhancements are always welcome! [=

Than ks!

Hi!

This is my very first post here at the forum, and I wish I can explain exactly what I need.

I'm a brazilian design student currently working on my final graduation project. Speaking roughly, it consists of a "living" sound sculpture, where the user can interact with it through a tangible malleable interface, producing generative feedback. More info can be seen at http://www.quando.art.br/devir (only in portuguese), or http://theinstrumentproject.tumblr.com (where I post the tangible instrument development status).

Bellow is a basic schematic of how I'm planning it to function (on the technical level).

I'm actually on a stage that I need to define which language is best suited for me.

The only things really well defined at my basic setup is the use of a Lilypad Arduino (witch 5 accelerometers parsing data through bluetooth), and on the audio output, Supercollider. I have some background using Processing - and I'm really afraid that I'l need a more robust programming language to handle all that at a good rate speed. As this is an interactive project, it is really important that the feedback is consistent and fast enough.

Questions:

- Is Processing a well suited language for my project? - It should be able to communicate easily with Arduino, parse all the data, handle the cellular automaton system, generate the visual output and generate data outputted to Supercollider. The visual feedback will be as complex as it can get with the responsiveness I get. I was wondering if openFrameworks or Cinder wouldn't be the case for this...

- Does anyone have any idea, trail or have seen a similar project that can contribute with my development?

- Can you indicate some "key-libraries" for what I'm intending to do, or even programming concepts and frameworks suitable for this?

I'm REALLY open to whatever contribution you might have to me at this stage. My time schedule is really short, and though that, I'm really excited on putting my hands on this! :D

Thanks!

Call to arms: malleable interface creation!

Hello!

My name is Luiz Gustavo, and I'm a brazilian design student. First of all, this is my very first post at this space, and I'm very very open to hear whatever critics or opinion of everyone. My hardware & electronics knowledge is very limited, so I'm opening the whole creation of the following project to whoever is interested in co-creating it with me.

As part of my ongoing graduation project, I want to create a malleable interface using textiles. The idea is pretty simple. I want to create an open-source hybrid object, a digital raw data generator, consisted of a highly malleable interface that is capable of being folded, twisted and adjusted to the will of its user: an interface as simple and soft as a piece of silk fabric.

The data generated must give the current state (deformation and positioning) of the malleable object to a digital output in realtime. The malleable object has to be modular, as well as a little stretchable. I really want to create something that can be remounted, modified, and used in different kind of contexts - not so only as my main purpose at the creation of an experimental art installation I've been working on as my graduation project.

At this website I've posted a larger description of my intentions with this interface, as well as a first draft of it:

http://theinstrumentproject.tumblr.com/

I'm not quite sure how's that going to be done, what have already been done in this area, what kinds of open hardware I can use, sensors and so on. I'm really starting this research right now, but it would help a lot to at least hear some possibilities from anyone. I'm very very open to hear any kind of contribution!

Thanks! [=

Best regards,

Luiz Gustavo.
