We are working on a new project called A.O.S.C. – agents of synchronicity. More about the project soon. But for the start here is the description of the building process of a microphone for that project.

We need a simple mono microphone for long time outdoor usage at a fixed place. We decided to use the Primo EM172-Z1 electret capsule because it is not too expensive and the sound quality is quit good. We bought it directly from Primo in Germany.

Primo EM172-Z1

Using some heat shrink tube,


a piece of a pipe for electrical installations from a hardware store and some Sugru to fix the capsule inside:


A 3d printed ring and rubber hair bands as shock mount. For wind protection we have attached a piece of foam and a Rode fur for Lavalier mics onto the capsule

The house for the mic is a filter of a pump for a garden pond from the hardware store which is then covered by nylon socks..

Residency in Sydney

During october 2015 blackhole-factory stays as Artists in Residence in Sydney as guests of SOPA Sydney Olympic Park Authority
Our special thanks to Tony Nesbitt

The place:

The Armory - building 20

Newington Armory in the Sydney Olympic Park is an old magazine for gunpowder and later high explosive ammunition for the army until it was changed into a public park for the Olympic Games in the year 2000

Here we are:

We are staying in a beautiful cottage in the park, in a fantastic and peaceful environment. Working in a spectacular studio in building 20 of the Newington Armory. The old storage for weapons has its special atmosphere and great acoustique. A perfect place for our research on the new piece “Die Erschütterung der Welt”, which will be shown in Braunschweig by February 2016.
We are setting up the wireless sensor network for the project and testing different modes of integrating it into the stagework.

Beside our research work we are doing a lot of public activities. See the timetable here:

Oct 2: Hacking the Stage – lecture about blackhole-factory concepts of work at CCS in the University of Technology in Sydney

UTS Sydney

Oct 3-5 and 17-18: we present some installations in the studio for the public.
Workshops are being held In collaboration with the Sydney based arts collective tranSTURM and musician Roger Mills about the common work under the title “Waterline”.
In the exhibition we show “The Flight of the Seaswallow” as an interactive installation, fragments of the work with the wireless sensor network, our “CamBot” and some other sound experiments.

Oct 7: Martin Slawig live playing with the Ethernet Orchestra at Parramatta Lanes Festival. The concert being planned for Oct 9 had to be cancelled because of a protest demonstration on the streets against a mosque in Parramatta.

Oct 8 blackhole-factory played SnakeRiverDream as a live set at FBI-Radio ‘Ears Have Ears’ as guests of Brooke Olsen.

Oct 21-22: a series of workshops happens as a part of the Youth Eco Summit (YES) in the Olympic Park.

Oct 28: Ethernet Orchestra concert. After years of playing networked concerts blackhole-factory and the Sydney based members of the Ethernet Orchestra are meeting for the first time  live on stage: Roger Mills, Yavuz Uydu, Bukhchuluun Ganburged, Shaun Premnath + streamed from Londrina Brazil: Chris Vine

Martin Slawig: live processed objects
Recorded during a one week stay in a cottage at a lake near Fürstenberg, Mecklenburgische Seenplatte in the former German Democratic Republic (GDR).
It is a large forest area with lots of lakes where you can walk for hours without meeting anybody. And it is near the former Neuthymen Nuclear Missile Base of the Soviet Armed Forces in Germany. This area is now abandoned. But it is still surrounded by a large concrete wall and barbed wire. Warning signs along the wall and the trees at the street through the forest mark the area as a very dangerous place. It seems to be better not to walk in this forest. Nobody knows how much old ammunition rests have been buried in the ground.

Dance_Code is a project by the dancer Agnetha Jaunich (Kassel) in collaboration with blackhole-factory, exploring the possibilities of transforming movement and sound into 3d graphics in an improvisation.

The movements of the dancer are tracked by a kinect sensor and mapped to the position and shape of the 3d object. The frequency spectrum and amplitude of the sound are changing the texture and distortion of the object.

Agnetha Jaunich – dance
Elke Utermöhlen – voice
Martin Slawig – percussion + live processing, programming

The project is supported by Kulturinstitut der Stadt Braunschweig

It is based on the NurbsSheet patch from the Physics-Patch-a-Day thread in the cycling74 forum.
In this test the movement of the 3d object is generated randomly. It will later be connected to the hands and feet of a dancer tracked by a kinect.
The sound is generated by using an induction coil which is moved over different parts of the laptop and then live processed using Max/MSP. The result is sent to a second laptop to influence the visuals.

TiG – Rhythmusmaschine

[vc_row][vc_column][vc_column_text css=”.vc_custom_1552904622912{padding-top: 20px !important;padding-right: 20px !important;padding-bottom: 20px !important;padding-left: 20px !important;}”]The TiG – Rhythmusmaschine is an interactive installation for the theater performance ‘Der Grosse Kreis’, a performance related on ‘The Rite Of Spring’ by Igor Stravinsky.
(More informations about the project on the TiG website)

The TiG – Rhythmusmaschine is a 4 track sequencer with an user interface projected on the stage floor. The sounds can be changed via live sampling by the performers using a sensor box and a set of percussion instruments. The performers are creating rhythms by placing white styrofoam balls in the projected field or dancing in the projection.

This video shows first tests with the installation:

And this is how the whole performance looked at the end:

The whole project is realized in Max:
A sensor box on stage with 4 ir sensors and an arduino board is connected to Max via xBee radio modules. It is controlling the live sampling and some stage lights as signs for the percussionist.
Max is also used to play the triggered sounds, for the camera tracking and the projection on the floor. The light design for the whole performance is also controlled using Max.[/vc_column_text][vc_column_text css=”.vc_custom_1552904662689{padding-top: 20px !important;padding-right: 20px !important;padding-bottom: 20px !important;padding-left: 20px !important;}”]
