Workshop with Kacper Ziemianin: Constructing DIY Arduino-based instrument μLSe

4/11/2025 from 10:00 until 17:00, Audio Studio U14/107

The workshop is organized by the Department of A/V Technology in collaboration with the Sonda festival and will focus on the principles of DIY electronics and the creation of experimental instruments.

Workshop description: This workshop grew from more than a decade of experience in instrument design on one hand and giving DIY electronics workshops on another. During workshop we will construct an instrument called μLSe and by following this process learn about various aspects of instrument design. We will start with introduction to DIY electronics and talk about skills and tools involved. The main part will be about implementing what we've learnt by putting the device together, connecting it to the computer and uploading code and making sure it works (troubleshooting). Finally we will look at ways to change how the instrument behaves by altering the code. In the meantime we will look at examples of artworks utilizing Arduino platform and discuss participants individual projects ideas and how to make them into reality.

Description of μLSe instrument: μLSe is a hands-on, Arduino-based sound device designed specifically for workshops. It's a younger sibling of LSe (Light Sequencer) instrument which uses complex light sequences to generate and control sound. While the original LSe is powerful, it’s also costly and time-consuming to build. μLSe keeps the core concept of transforming light patterns into sound in a simplest possible way.

The device features: 2 RGB LEDs and 2 light sensors for creating interactive light/sound patterns, 2 buttons to switch sound and light modes, a mini speaker (or piezo) for built-in audio playback and a 3.5mm jack for external audio output.

Kacper Ziemianin a.k.a. ‘Ctrl Freq’ has background in classical music and a lot of adventures in modern sound and music. He holds a Bachelor’s degree in Sonic Arts from Middlsex University, London and Master’s degree in Sonology at the Royal Conservatory in The Hague, the Netherlands. Instrument maker, sound designer, circuit bender, vagabond, improviser, producer, audio-hacker, nomad, radio presenter, activist, workshop leader, squatter. His audio installations and sounds have been shown/played in numerous places around, as well as outside Europe. Currently based in the Hague, NL working as a freelance instrument designer and performer as well as teacher of DIY electronics. His latest endeavor, the ‘LightSeq’ has received funding from Stimuleringsfonds NL and won an award at an international electronic music festival ‘Radical dB’ in Zaragoza, Spain.
