After participating in the exceedingly successful Hackterialab2011, Øyvind Mellbye returned to Norway to pass on the technology of D.I.Y Microscopy at Atelier Nord in Oslo from 2-4.september 2011.
During the workshop we made microscopes from usb webcameras and went hunting for nematodes in the soil in the surroundings of kunstnernes hus.
The basis for our microscopes in this instance was the ps3 eye camera which has good optics and a quite large image sensor. During the first day the cameras were hacked by reversing the optics and soldering LEDs to the circuit to illuminate the samples.
Then we made Baermann-funnels that simply consist of a funnel with a plastic tube and a filter separating soil and nematodes with nematodes being able to crawl through the filter and gather in the plastic tube sealed by a clothes-peg.
On the second day of the workshop we discussed various functions and practical aspects regarding the construction of the stand that should keep the sample in correct position in relation to the lens and sensor.
A workshop drawing of a microscopestand with the ability to adjust the distance between the sensor and lens for various degrees of magnification and also to focus on the sample was the starting point for the microscopes that we made.
Through the second and third day of the workshop the microscopes was finished.
For unknown reasons the Baermann-funnels didn`t turn out to be a great success teeming with nematodes, but instead a rather barren sample with sporadic specs of soil. So there is absolutely room for improvement on the funnels. Perhaps coffee filters are not the optimal choice for extracting nematodes. But this did not in any way discourage us from further microscopy. Avocado, hair, salt, eggshell, sheepfat, creamcheese, leaves and other materials was subject to the gaze of the microscope.
Nur Akbar Arofatullah (1987) is an independent researcher currently working at the Departement of Microbiology of Agriculture Faculty UGM Yogyakarta, Indonesia. He focused on the field of fermentation techniques in various system such liquid and solid-state fermentation. Several of his main research are bioethanol fermentation from sweet sorghum juice, biofertilizer, organic farming, and sillage fermentation for cattle feeds. He is a co-founder of “Bangun Indonesia” organization where he is actively giving trainings and workshops about Bio-activator, liquid organic fertilizer, compost, livestock-woof fermentation, and bio-pesticide for the farmers and local citizens of Yogyakarta and Central Java. His current research project is an in vitro method for establishing mycorrhizae on elais guineensis tree.

We are now in the final stage of HackteriaLab2011, which we have called the Reflection. In Kunstraum Walcheturm in Zurich we are staging an exhibition, workshops and a series of presentations and discussions in order to share with the public the techniques, ideas and experiences we have gained over the past few days at L’ARC [...]
Tuesday 1st August (Swiss National DAy) – HackteriaLab2011 day 4:
Nestling in the picturesque foothills of the Jura mountains, the sleepy village and monastery of Romanmotier is witnessing the combined weirdness of about 30 artists, hackers, scientists and others that refuse to be classified. Across three large workspaces on two floors people are building magnetic stirrers [...]
The second international HackteriaLab takes place this year at the 12th century monastery L’Arc in Romainmotier, Switzerland, from the 28th July to 4th August. Following on from the success of last year’s slightly more modest HackteriaLab at Dock18 in Zurich, this year we have invited around 20 artists, scientists, DIYers and hackers to spend a [...]

An Oechslemeter is a simple instrument to measure the relative density of a liquid. its also called an Aräometer or Hydrometer. The measure of Oechslegrad (degree Oechsle, ° Oe), also “must weight“, is used in the German/Swiss wineculture to specifiy to the sugar content in the fruitjuice, thus the change of the Oechligrad before -> [...]
