Recently I have been working intensively to finish a new project called ‘Ursae Minoris’, in collaboration with composer Claudio F. Baroni and double bass player Dario Calderone. It is based on a musical score in three parts for double bass and electronics that Claudio Baroni […]

fine distinction

Since I wrote my somewhat longish post on analog computing, many things have happened. For instance, I have become the proud owner of an EAI TR-48 analog computer from 1963, a machine to which I will devote a future longish post with plenty images as […]

scanning electrometer

At the moment I am working to improve a rather elementary sensor for electrostatic fields, in an attempt to use it to make images. Since I do not really know what these images should look like, that brought me to an interesting and unexpected philosophical […]

analog computing Analog computers have intrigued me ever since I saw one for the first time and had no clue how to operate it, despite the fact that it looked very familiar with its patchpanel and knobs; superficially not very different from an analog modular […]


xy recording

  As an unexpected side-track of my current interest in analog computing, I found myself today making analog ‘programs’ to be drawn on a XY-recorder I recently bought. XY-recorders are the direct precursors of plotters, which are themselves the direct precursors of the raster printers […]

a blind man and his cane according to Descartes


  At the moment, I am busy building my new installation #53 in DordtYart in Dordrecht. It will open coming Saturday, the 6th of September, from 14h to 18h. In #53, the viewer sees spatial colours that depend on her position relative to a luminous […]
