RND Bitmaps   code, print     apr 2016
vidr Still from David Cronenberg's 'Videodrome' (1983)

What is on that poster in Max Renn's kitchen? At first glance it looks like plain random binary noise, but closer inspection reveals certain regularities. Any algorithm to produce something similar is certainly not just based on random noise alone.
Attempts to reverse-engineer the algorithm involved have led to several variations of such bitmaps.

Mole-Rat   audio device     sep 2015
The Mole-Rat is an EMF audio device that allows you to explore the electromagnetic fields in your direct surroundings. The device is available via noizumashin.com

Black Square Projector   installation     jun 2015
A handmade projector that is fully programmed for one task only.
At regular intervals, the device projects a bright white square, the negative afterimage of which is revealed in its wake for a brief moment in time, and as such only in the mind.
Creating a black square with the absence of light, the installation is ON when OFF.

Presented at the Black² exhibition at Project Ground Moscow, Jul-Aug 2015.
Works by Julia Borovaya & Eduard Rachmanov, John Cage, Evelina Domnitch & Dmitry Gelfand, Vladimir Grafov, Edwin van der Heide, Bas van Koolwijk, Labofactory, Gert-Jan Prins, Frederik de Wilde.

Delay Line Memory   live set     sep 2014
Through interference between sound waves traveling with divergent frequencies, rhythmic variations of audible patterns can be created.
Here, such patterns are temporarily stored within a 'delay line memory', a form of sequential access memory that was used for early computing. By delaying the data signal, it is effectively memorised for a given period of time.
Within the framework of this memory, a two-dimensional visualisation of its contents exposes patterns that otherwise would have remained hidden.
Supplemented with drums this live set results in improvisations between drums and digital electronics.

Live performances:
apr 6 2016, with Gert-Jan Prins (drums), Semaine Digital, Bordeaux FR
feb 11 2016, Van Koolwijk solo, TEC-ART, WORM, Rotterdam NL

FDBCK AV - Curvilinear   live set & video     sep 2014
For the Fdbck AV live sets and releases, Van Koolwijk has created a feedback control circuit between audio and video data, making these into two facets of a self-sustaining data stream.
By manipulation of the ensuing processes, the system becomes an audio-visual instrument.
This version of the live set was especially created for projection within the Sphæræ dome.
A 12 minutes video with the same title was released in september 2014.

Live performances:
sep 12 2014, Sphæræ, GOGBOT Festival, Enschede NL   sphaerae.net
Screenings:
sep 26 2014, Sphæræ, AxS, Pasadena CA, USA   axsfestival.org

SPH1

Mercury to Saturn, including Earth     may 2014
98 compositions of flight paths to the planets of our solar system.
An audio-visual installation compiled of scans from a report commissioned by General Atomic, published in February 1966 as part of a series of reports examining the possibilities of propulsion by nuclear explosions for future space travel.
After image analysis, the supplement of Nuclear Pulse Vehicle Study - Vol. IV appeared to contain some surprising rhythms.

Vertical projection HD, looped, 20 minutes.
The work is to be projected on a custom-built freestanding wall of which the proportions correspond to those of the visuals.

Exhibitions:
sep 11-14 2014, GOGBOT Festival, Enschede NL   www.planetart.nl

SYNCHRONATOR workshop     feb 2014
The Synchronator device converts electronic audio signals into composite video signals. Since its release in 2009, it has seen a steady growth in the number of users.
During this workshop, we will introduce you to the background, techniques and use of this device for live improvisation and recordings.
Each participant is invited to work with the Synchronator devices and television monitors, ask questions, and engage in hands-on experiments.
Your instructors: Gert-Jan Prins, Bas van Koolwijk, Tina Frank.

The workshop was organised by Sonic Acts and STEIM within the context of 'Sonic Acts - Vertical Cinema' on 21 February 2014 at STEIM, Amsterdam NL.   sonicacts.com   steim.org

SYNCHRONATOR ColorControl     dec 2013
The SYNCHRONATOR ColorControl is a device for mixing two channels of audio into an RGB Triphonic signal. Its output is to be connected to a SYNCHRONATOR < audio to video > device in order to create a composite video signal.
The ColorControl has two controllers for hue and two sliders for setting the saturation for each input channel. Depending on the hue and saturation settings, the signal is proportionally divided over the RGB Triphonic outputs.
Unlike regular audio equipment, which works fine for sound within the hearable range, the ColorControl can handle frequencies up to 4 MHz without affecting the quality of the signal.

RUNAWAY AV     sep 2013
In synthetic biology, modular biological functions are used to build novel biological devices and systems. In this regard, similarities between the design of biological systems and that of electronic equipment are quite obvious.
But the most striking difference between the two must certainly be the fact that the development of a biological system continues after its construction. It grows.
In this audio-visual performance it is the software that gradually gains autonomy, resulting in a runaway process whereby the system continues to develop a growing complexity.
RUNAWAY AV was made especially for projection in the dome of the Sphæræ project.   sphaerae.net

Live performances:
sep 7 2013, Sphæræ, Ars Electronica, Linz AT
sep 27 2013, Sphæræ, Today's Art, The Hague NL

UNCLASSIFIED     jul 2013
An audio-visual installation based on scans of a complete series of 14 technical data reports from June 1966 to September 1966, commissioned by NASA. These reports were made in the context of the Apollo program, in preparation for the lunar landings.
The pages are shown in chronological order of the recorded data as a looped sequence of 4 minutes.

The systematic approach of the research as evident on consecutive pages, creates the illusion of movement and gives the individual reports their own rhythm.
Data obtained by virtual re-scanning of each individual page is digitally converted to function as a soundtrack.

The work is to be projected on a custom-built freestanding wall of which the proportions correspond to those of the visuals.

SYNCHRONATOR device (second edition)     nov 2010
After the successful launch of the first 100 devices, another batch of 100 go on sale.
The SYNCHRONATOR device transforms your audio into a composite video signal, compatible with all video equipment supporting composite video input.
With 3 audio inputs and 1 video out, the SYNCHRONATOR device enables you to visualize your sounds on each of the primary color channels of the video signal. It adds video sync pulses and color coding signals to your audio, effectively disguising the input as a composite video signal. The device is powered with a 6V adapter and features a color/b&w switch as its only on-board controller. The second edition of the SYNCHRONATOR device is again limited to 100 units.
It is shipped in a box with DVD, manual, 6V adapter (US and EU) and composite video cable.

SYNCHRONATOR dual screen - single display     oct 2010
Due to frequent technical difficulties concerning equipment at venues for performances, a system for 2x video to 1x WXGA had to be developed.
Resulting in a software application and a combination of specific video capture devices to establish a fast and reliable method for placing 2 SYNCHRONATOR video inputs next to each other in one WXGA output signal. The system adapts to several resolutions and enables the best possible output quality.
First used for a concert on nov 6 2010, LAMPO/Graham foundation, Chicago IL USA

SYNCHRONATOR automated colour interface     mar 2010
A USB device and software application for automated colour adjustment during SYNCHRONATOR performances.
Through audio analysis, specific peaks and transitions are detected that are then set to trigger colour changes in the output of the SYNCHRONATOR device. The colour is changed by automated mixing of the 3 analogue sound signals to the inputs of the SYNCHRONATOR.
The software can be programmed to respond to any detectable changes in the sound input.
