Overview Experimental make-workshop with multilayered outcome for people interested in sound, DIY-biology, microscopy and interaction of living microorganisms. Knowledge in physical computing, video and sound processing, electronics and puredata is welcome, but not compulsary.

Description In this workshop the experiments will take place in close-up view of microorganisms (e.g. water bears aka tardigrades,amoebae and collected organisms from urban environments), which appears to be a world by itself. Maybe due to the scaling and the amplification of a microscope, but maybe also due to all parameters of imagination that the microcosmos provokes. Growth and behaviour of these microscopic animals remind us of our own micro-macro-development. With the image and the movement of the organisms, the participants are encouraged to collect inspiration and bridge video and sound to what they experience with these small “animalcules”, as termed by their first observer Leeuwenhoek in 1677.

The participants will learn How to work with the usb-microscopes and hack webcams to be used as microscopes, observe the behaviour and motion of the waterbears and other microorganisms, find sounds from the lab equipment, hack into electronic devices to integrate into bioelectronic culture devices and build habitats for the animals. Also they will discover sounds from the different instrumentation and utilities of the laboratory. Recycle and compose arrangements for Lab-visual and Lab-sound scapes and benefit from a cross fertilization between the whole (scientific) equipment (you can bring your own too!) and an artistic metaphorical language. The outcome can be a video with a microscopic soundtrack, a living object with singing waterbears, a performance with laboratory sounds, or an openLab Hackteria installation.

Material needed The participant should bring their own laptop/computer, a webcam with an adjustable lens and some general lab stuff they have access to.

Material available various labware, glassware, petri-dishes, usb-microscopes, microorganisms, soldering stations, electronic parts, arduinos etc..

DIY microscopy

To use a simple usb webcam as a microscope, afew modifications are needed which are described in detail on the diy_microscopy page.

in short, a small hack to the optics of a standard webcam with an adjustable focus-lens, allows to create video data, with a magnification of around 100 to 400x (depending on the model) at a working distance of a few mm. the highest magnifications can be achieved by inverting (putting upside down) the lens. addition of good lighting by the use of leds allows to create images using a bright-field method (shine through the stuff) or dark field method (look at the reflections and scattering).
