Václav Peloušek & Bernhard Rasinger: Build your own handheld digital oscilloscope


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!


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
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.
