ideas research movies instruments
after a great ride through, up and down the alps i arrived in ljubljana...
spending a night below the stars in Obergail, sleeping a first time in my new car and finally met with stefan doepner, f18, to work the next few weeks on nanošmano in kapelica gallery. and now i need to find venzha... hmmm
Just done further experiments with the hacked optical mouse sensor, in this case a Avago ADNS2610, from a cheap wired logitec optical mouse. So i managed to connect the optical sensor to the arduino and send all the data, including the image from the 18x18pixel sensor, through a serial connection to puredata (pd). The sensor is a real high-end device, it calculates the optical flow, thus gets out motion and the speed of the mouse, it detects focus by a SQL-value, which is proportional to the number of features the sensor detects on a surface. and other values such as maximum and average pixel and shutter speed can be read from the registers.
The frame rate of the transmitted image is sadly relatively low, cos the ADNS chip is not meant to present this info at higher speed. still its reasonable, when reading all 18x18 pixel a framerate of roughly 5 fps is feasible, if you only dump the first couple of lines you can increase it to higher framerates.
After building a patch to visualize all these data from pd, i started experimenting with placing microorganisms on top of the sensor, keeping the optics intact, but replacing the LED with an RBG, so i can control illumination.
I got some really amazing results, it seems i can detect single cell microorganisms using just the mouse sensor and an arduino. see the movie below. while the sensor only detects motion if the whole image is shifted, it seems that when a microorganism (Blepharisma Japonicum) passes the field of view, there is a substantial change in the SQL-value.
further i will try to do some simple image processing on the arduino directly, such as simple background substraction.

The code for the arduino and puredata can be found here (work in progress):
* The arduino code, uses two libraries: pitches.h and SimpleMessageSystem.h. the first is just used to play a nice little welcome melody, the second is only needed to communicate back from pd to change the dumpWidth of the frame. copy them to your libraries folder.
* The pd patch uses two externals, "convert" to communicate with SimpleMessageSystem" (again only from pd to arduino not vice-versa) and a second one, "pd_fire_grad" to apply a look-up-table (LUT) to the pixels for better visualization.
I have just been doing more experiments using fluorescent dyes. Yesterday at the OpenLab, by SGMK, we messed around with solution of fluorescein. Was great fun. Thinking about ideas to use it for displays. only sometimes it looks almost too cheesy, to much goaparty-style. but with the right context, it might perfectly fit in. Fluorescence is in the end one of the key tools for doing biology and nanosciences.
I just tried to get some experience using the DIY microscope to detect fluorescence and nanoparticles. A friend of mine gave me some polymer-based hollow nanoparticles, designed for drug-delivery, dispersible in water and containing fluorescent dies. The fluorescence seems to be easily detectable even by eye when illuminated with an UV-LED. I guess I need to build a dark box around the microscope to test it more in detail or maybe only work at nights....

We are apparently now in a situation where modern technology is changing the way people behave, people talk, people react, people think and people remember. And you encounter this not only in a theoretical way, but when you meet people, when suddenly people start forgeting things, when suddenly people depend on their gadgets, and other stuff, to remember certain things. This is the beginning, its just an experience. But if you think about it and you think about your own behavior, you suddenly realize that something fundamental is going on.
... It's the question: what is important, what is not important, what is important to know? Is this information important? Can we still decide what is important? And it starts with this absolutely normal, everyday news. (Frank Schirrmacher/Editor FAZ, Germany)
f18institut Ljubljana/Hamburg together with dusjagr labs Zürich will establish an artistic research on nanotechnology, beginning 2010 with their first collaboration.
As the field of nanotechnology is far too broad to be investigated as a whole, we will start with a preliminary project in the field of nano-biotechnology. While nanotechnology deals with all natural and artificial phenomena at the lenghtscale of nanometers, only a few atoms, it is also the meeting point where all modern disciplines merge and have to find a common language. Allthough a real world experience of this nanoworld is difficult to achieve and can only be perceived by the use of modern scientific instruments, logical abstraction and modelling, we will try to develop possible tools to find, build, sensorize, evaluate, see and manipulate biological nanostructures, such as motorproteins and protein-coated nanoparticles. We think that an artistic interpretation of these allows further insight into this world and produce experiencable and metaphorical realities of modern science and technology.
Within the context of a simple approach and DIY philosophy, our tools will be comparable with knowing 3 chords on a guitar and playing punk music, one does not really now the whole context – but gathers experience and examples for new developments – while creating new artefacts.
The project will kick-off with a project presentation and discussion, followed by a intensive reasearch, experimentation and production phase of 10 – 14 days by Doepner and Dusseiller.
We will investigate to create structures, systems and situations with possible artistic value. It is about basic research on how to work on simple ways with nanotechnology, accessible to artists in labs and ateliers, and any more its possibilities for social and artistic value and relevance. Further on the project will consist of audiovisual and physical examples of our developments, as well as of self generated and semi professional tools for biological nano experiments.
Finally we will present an installation, which will represents our research, trials and errors, achievements and critical reflections. The final object should be the [Nano-Schmano] Object, an interactive, nano kinetic light and sound installation, based on Kinesin Motor Proteins and protein-coated nanoparticles, in which the visitor can change and controll through electromagnetic force and light emmissions the patterns and behaviour of those nanostructures.
Their actual activities/reactions will be audiovisually processed and translated to be observable, audible and graspable.

Motorproteins
Motorproteins are a family of abundant biomolecules that can perform mechanical work. For example as active proton pumps rotary motors in the cellular membrane, the acto-myosin machinery of muscle contraction or the kinesins, which are responsible for transport of material through a cell by "walking" on microtubule filaments. With the merging of biology, robotics and engineering at the nanoscale, scientists have developed hybrid systems that use these biological machinery for engineering applications, such as microscale transport networks, so called NanoShuttles (Vogel V, Hess H, NanoShuttles: Harnessing motor proteins to transport cargo in synthetic environments, Lecture Note Proceedings, Nobel Symposium 131 (2007) 367-383).

Stefan Doepner studied Painting and Experimental Film at the University of Arts Bremen.
Doepner's focus is on the artistic exploration of today's use, reception and rules of technology, to analyze and understand contemporary systems and techniques he acquires the method of reinvention.

About Hackteria/
Hackteria is a collection of Open Source Biological Art Projects instigated in February 2009 by Andy Gracie (UK), Marc Dusseiller (CH) and Yashas Shetty (IN). The aim of the project is to develop a rich web resource for people interested in or developing projects that involve DIY bioart, open source software and electronic experimentation. As a community platform hackteria tries to encourage the collaboration of scientists, hackers and artists to combine their experitise, write critical and theoretical reflections, share simple instructions to work with lifescience technologies and cooperate on the organization of workshops, festival and meetings.
