Arduino Workshop, Part 3

Today’s Lesson was about the IF :lol: – ELSE :sad: command. The physical example we used for that was:IF you turn a potentiometer underneath a certain vale, make the LED blink. To keep things easy we used pin 13which has a resistor built in to let the LED blink. I wanted to make things a bot more spicy and also make use of the ELSE IF and ELSE command, so i decided to make a wiring wiith a second LED on pin 12 that work like that: If the value received from the potentiometer is below 100 let LED1 blink, if it’s between 100 and 300 let LED2 blink, if the value is above 300 switch both LED’s constantly on.

Arduino Workshop, Part 2

Today it was fast and painless: Analog inputs. Easy but handy, basically any variabel resistor works like this. Check out the pictures for the schematics:

Immodesty, Day 1

I’ve chosen to join Karolina Sobecka’s Project mmodesty. We’ll build o low-cost virtual camera system. Therefore we will hack a bunch of single-use cameras in order to make them readable and release at the same time.

1st day: We started to break up some PDA readers that use the same interface like the single-use cameras.

cam_interface

The plan is to connect 30 cameras to one arduino in order to release the shutter simultanously. To do so we need to extend the outputs of the arduino, which originally has only 13 outputs. So, to get the ammount of output needed we built a Serial to Parallel Shifting-Out with a 74HC595 chip as explained on the arduino hompepage.

shift_out

Since the hardware tasks of the day were fulfilled with excellence we started a test shooting with one of the cameras. Our testsetup was a half circle with a radius of 3.2m, with marks every 20cm.

this is the output of the first testshooting: file formats troubles

Arduino Workshop, Part 1

This week we’ll have an arduino workshop going on besides the projects we’re working on.

Today we started with basics of electronics and arduino. Therefore Simone Jones Continue reading ‘Arduino Workshop, Part 1’

Interactivos, Day1

Today, all the selected projects were presented by their creator, we now have to choose one or more projects to collaborate with. Here is a short summery of all the projects:

Esther Polak: Sand Spiral Machine
http://spiraldrawingsunrise.wordpress.com/

The idea is to build a robot that uses solar power in order to move that is nonstop drawing a line of sand. When it has collected enough power it will move: When the sun rises, the distances the robot can make will rise because the amount of light that hits the solar panel increases. The line of sand will visualize this process.

Collaborators should know:

    – electro-mechanical: motors, condensers, etc.
    - solar power
    - programming skills for arduino
    - sand flow research
    - conceptual and visual impact reflection
    - local research: find nice spots to test
    - photography and video documentation
    - writing and text correction for the blog

Paola Guimerans, Horacio González, Igor González: Biophionitos

In the nineteens century a lot of techniques came up in order to generate moving images like zoetrope (-> wikipedia)
A processing application will include polygons. this polygons are used to create images of pets, which can then be printed out to create your own animation generator at home – the idea is to make it easy to build, in order to animate people to build it at home.

    – processing
    - electronics
    - mechanical knowledge

biophonitos

Jordi Puig: MASK
(My Alter Self Consciousness)
The idea is to have a magic mirror that paints masks and animations in your face, so you’re not looking at a screen but at image of yourself. in order to do this we will use a spy mirror and project behind that to mix the mirrored image and the projection. we will use camera tracking to determine the position of the face/ projection. So the most work will be in face recognition and tracking on one side, on the other side to design and implement the animation.
mask

Nova Jiang: Stage Fright
Nova will build an interfaced swing that will trigger video movement in order to use the swing to navigate through a narrative story or to amplify the experience of a swing.

    Week 1:
    build the swing
    interface the swing
    Week 2:
    creating footage

swing

Philippe Chatelain: 360º score
laptoporchestra.net

Phillipes wants to create a device that can scan drawings and then generate sound out of them.
According to the nature of the graphics and the location of the user within the exhibition space the nature of the sounds may vary.

360°

Walter Langelaar: Daedalus_ex_Machina [DexM]

The main point of Walter’s idea is to bring life video into a virtual representation of a space.
This he will realie in the quake engine which he found a code to implement life video for.

In order to realize this within the quake engine he wants to use and improve (resolution) an open source code he discovered recently and than rebuild the space of the medialab-prado and use the live video signal as a shader.

Karolina Sobecka: Immodesty

gravitytrap.com

Karolina will use cheap “one-way” cameras and hack them that each camera is wired to an arduino to press the shutter release automatet and simutaniously and that it’s actually possible to download pictures from these cameras. The goal is to creat a cheap virtual camera and then build an installation with this.

.collaborators:

    – camera hacking
    - fabrication: design and production of the camera rig.
    - building electronic circuits with micro controllers
    - ideas for how to use tis kind of system
    - video post production

cameras

Eloi Maduell: augment(0)scope

the basic idea is to create an interface to show augmented reality.
[i'm sorry - he was so fast that i couldn't follow the whole thing s i just copy/paste]

“The idea is to make something similar to the old “optical boxes” developed on the 18th century. “Optical boxes” were wooden boxes where you could see, through a lens, engraves and daguerreotypes that allowed you to “travel” to remote places. This project plans to create an “optical box” using artificial vision technology and augmented reality techniques, thus overlapping “video” realities and “digital” fictions. The box will be hanging on the ceiling over user’s head, so she can freely rotate it on the space.”

Anaísa Franco: Expanded Eye

Anisa brought a huge acrylic sphere that she wants to use to project the eyes of the observer on
at each blink of the eye one more eye will be projected.

first five days: create the installation
next ten days: develope the information

collaborators: openFW, vvvv

eye
:[i'm sorry for your laptop, btw]:

Martín Nadal: Bloop

As far as i understood he will use an online interface to distribute frames of one second of video to different people around the world and ask them to redraw the frames and then send them back.

collaborates: who can think about an interesting interface? web programming interface would be handy…

Interactivos?’08 at Medialab-Prado, Madrid

Interactivos?’08: Vision Play event will take place from May 30 to June 14, 2008. This seminar-workshop will be directed by Alvaro Cassinelli and Simone Jones, with the participation of Daniel Canogar, Pablo Valbuena and Julian Oliver. Besides the two-week workshop, seminars, lectures and miniworkshops will also be held by Nuria Valverde, James Elkins, Susana Martínez-Conde, José Luis Brea and Jimena Canales.

I was invited to take part in the workshop, so i booked the flights and here i am! The workshop will start tomorrow in the Medialab-Prado and i will take chance to finally use tagr.tv as a workshop documentation plattform and try to spam the blog with an everyday update of the workshop.

Examples for projects that had been realized during recent Interaktivos? workshops are for example Chris Sugrue’s Delicate Boundaries or Pablo Valbuena’s AugmentedSculpture which i think was one of the most thrilling works exhibited at the Ars Elektronica 2007.

Saturday Night @ Share Festival: Bong-Ra

bong ra monitor

ok, lets keep this straightforward: this is the monitor he used to perform with, thanks to super-charming ella esque we were able to plug the recorder directly to the mixer and you can find a proper 320kbps .mp3 bootleg from his performance here, and this is to give you a visualized impression of the party:

winner of the share prize 08

Christine Sugrue is the winner of this years share prize. Her work “Delicate Boundaries” satisfied the jury members bruce sterling, anne nigten and stefano mirti – Congratulation!

delicate.jpg

Jury Statement:

Anne Nigten — manager of the V-2 Lab and director of the Patching Zone in Rotterdam, The Netherlands.
Stefano Mirti — architect, designer, and teacher from I-D Lab in Milano.
Bruce Sterling, author journalist from Austin Texas and guest curator of Share Festival, chairman of the Share Prize jury.

So — as you may know, we three members of the jury were responsible for picking these six pieces of art. We love all of them dearly. Nevertheless only one can take home the SHARE prize — the digitally-manufactured SHARE Prize.

Our artists have created extraordinary works where digital images crawl out of screens and onto human fingers, where digital sound samples leave the computer to become solid chunks of wood carved on lathes. We also have a large, synaesthetic, immersive installation, two multi-user interaction pieces suitable for groups, and one of the scariest and most physically confrontational pieces of electronic art yet created.

We were much taken by D3D’s Virtual Identity Project. The fine Italian aesthetics work at an eye-candy level, while also raising substantial questions about identity and our data shadows on the modern net.

We very much appreciated the muscular appeal of our runner-up, Emmanuel Andel’s knife hand chop bot. This installation mesmerized everyone who saw it in action — it’s a fearsomely strong work of art, which provokes dripping sweat, racing heartbeats — it’s the personification of the hidden violence of new media!

It struck us that our winner and runner-up are the feminine and masculine version of the same artistic concept. It’s a pity they can’t marry — but only one can win.

With its mixture of subtle feminine menace and charm, our winner is a piece that was universally beloved by everyone who attended SHARE: Delicate Boundaries. We were encouraged by its poetics of social networking — everyone contaminated by these sprites immediately wants to share the infection with someone else. We also admired the sophisticated programming, and very clear and limpid user-interface. A hearty welcome from Torino to an American artist with global appeal, Chris Sugrue.

Honorary mention to Knife.Hand.Chop.Bot by Emanuel Andel.

to.share.it

if you appreciate good things like italien food, good wine and you also have a big crash on media art, the share festival in torino (IT) is the place to be right know. the italiens know how to make things perfect for bon vivants like they created a own wine label with the same sujet than the festival. impressively genial!

share grafitti

the guest curator of the festival is no less than bruce sterling. you may not connect him with media art but more with cyperpunk – but if you know his novels its quite clear that he is having an elusive good feeling for art. i am especially thinking of the episode in “schismatrix” were lindsay (main character) got the first contact to the just arriving aliens and is accidental perceived as an artist as he caused an explosion:

“are you the artist?”
“yes,” lindsay said. he pointed at the screen. “notice the subtle shading effect where our recent blast darkend the sculpture.”
“we noticed the explosion,” the alien said. “an unusual artistic technique.”
“we are unusual,” lindsay said. “we are unique.”
