Bernhard Rasinger & Václav Peloušek: How to draw with sound?


In this workshop, you’ll build a DIY laser projector based on deflection mirrors attached to any speakers. The basic idea is explained here.

The design of the projector follows a simple rule – you can build it with materials and tools you already have at home, your studio or at the local makerspace, you just need a laser pointer, speakers (any kind), little mirrors and a double sided tape. 

In the first part of the workshop Bernhard and Václav will guide you through the building process and explain the basic functionality of this tool. In the second part we will use various synthesizers and visualise their waveforms (as we learned in the first Modul@rnice lecture), while focusing on several other visualisation methods: professional laser projector, Vectrex, analog oscilloscope, digital oscilloscope, computer with a soundcard.

This workshop aims towards opening-up the creative usage of laser projections (are they really only available to big-budgets, dangerous, hard to get and complicated to use?), while encouraging visually driven sound exploration (vector synthesis). Since laser projectors or even analogue oscilloscopes are not that easy and cheap to come by or interface with, this project aims towards demystifying the vector synthesis while making it more inclusive, accessible and affordable. Furthermore, the project wants to encourage makers and artists to experiment with unusual setups and think outside of the standard usage of technology.

HOW TO APPLY: Bring your headphones, optional: modular synth or any other synthesizer and an oscilloscope. The workshop is free of charge and will be held in the English language. The number of participants is limited; you can apply at Attendees will need to meet the current RVT conditions.
