Václav Peloušek & Bernhard Rasinger: Build Your Own Handheld Digital Oscilloscope

Workshop is part of MENT Festival!

09 – 10 June 2021 | 4 – 8pm @ osmo/za, Ljubljana

In this workshop, you’ll build your own digital 2-channel oscilloscope WAVE2, which fits in the palm of your hand. It features two input channels and two auxiliary function generator outputs. It’s a fun little device that can be used to look at waveforms and do electronic measurements.

Bernhard and Vaclav will guide you through the soldering process and explain the basic functionality of this awesome tool. However, there’s an evil twist—we’re going to hack the oscilloscope kit so that you’ll be able to fit it into your Eurorack modular synthesizer.
The oscilloscope will be powered from the synth’s power rail and you’ll receive Eurorack compatible 3.5mm jacks to seamlessly integrate it into your modular synthesis workflow.

The workshop will also focus on the explanation of waveforms in XY and the process of drawing shapes on the oscilloscope. Before you know it, you’ll enter an ancient cult of vector worshiping!


Václav Peloušek is a musician, educator, artist, and founder and lead designer of the synthesizer company Bastl Instruments. He studied in Brno and at the University of Applied Arts in Vienna. With Ondřej Merta, he started the art and education project Standuino (2011), which later evolved into Bastl Instruments. Since 2013, the company has developed and produced many desktop synthesizers, effects, samplers (microGranny 2, Thyme, Kastle) and a whole range of Eurorack modular synthesizer modules. The company also collaborates with Peter Edwards (Casper Electronics) on several modules and instruments, for example the softPop and the bitRanger. Coming from a D.I.Y. artistic background, Peloušek’s conducted many workshops and happenings at festivals, universities and other venues (STEIM – Amsterdam, The Cologne University of Music, Superbooth and Loop – Berlin, MuseumsQuartier – Vienna, MENT – Ljubljana, PIFcamp – Soča, Shape Platform – Meetfactory Prague, Synthposium – Moscow, Fold – London). The company has also initiated countless local community activities, organised shows and even set up the Noise Kitchen store in Prague. From 2017 to 2018, Bastl ran the venue Herna in Brno. Since 2018, Peloušek’s been developing his solo musical project Toyota Vangelis under which he’s released several singles and EPs, and performed at events around Europe (Lunchmeat or Meetfactory – Prague, Synthposium – Moscow, Modular Day – Barcelona, CV Freqs – London, Klunkerkranich or Humboldthain – Berlin). He was artist in residence at Locatie Spatie in Arnhem in 2011 and at Opekta Studios in Cologne in 2012.

How to apply

Bring your modular synth (if you have one) or electronic sound devices to make epic shapes, and also a USB power source, like a phone charger, to power the device. The price of the oscilloscope kit is 50 € – all participants will receive an email regarding the payment process. The number of participants is limited; you can apply at delavnice@projekt-atol.si.
2 free applications: If you can’t afford the materials, but you’ve always been interested in the topic, you’re still kindly invited to attend the workshop. In this case, the final product won’t be yours, but two devices from the workshop will always be available to our community as part of our synth library at osmo/za.
