Spritzerbot

spritzer_pano

The Spritzerbot is a commisioned piece for monochrom. It is a cocktail robot which serves Kaiserspritzer, a mixed drink of wine, soda water and elderberry syrup. Its open and non-obfuscating design encourages to explore the working machanisms of the machine.
The insignia was meticulously designed by Luis Utrillas.

It was created for the food/cocktail robot festivals Hedonistika (Tel Aviv) and Roboexotica (Vienna).

Prost!

Fluid Communication

Zwischenablage02

Digital communication, in its electronic form, is invisible to the eye. We created a machine that visualises the flow of binary data, by using oil and water as binary states instead of voltage levels.

The software which serves as data source is a simple chat program. If the user enters text and sends it, the machine sends the binary representation of that text by alternately pumping clear oil and colored water through the tube. The two differents fluids represent the binary data: Oil for 0, Water for 1. The resulting black and white pattern is the decoded data sent from the terminal.

The machine communicates with itself, decoding the pattern it has generated. Through the turbulences in the tube the data gets distorted. This distorted data reminds us of the difficulties that one has to overcome to build reliable digital devices.

Fngism

fngism2

The Fngism is the official band synthesizer of the experimental performance group FNG. The circuit is based on various 4093 NAND circuit designs on the internet. It has a switch for unpredictable sound mayhem. The wooden casing was made by Bastian Enzenhofer.

The PCB layout was etched in a DIY manner with the direct toner method.

The Fngism as lead instrument:

Grav Spheres

A accelerometer & gyroscope mounted inside of a ball tracking its movement. Data gets streamed wirelessly to a MQTT broker. The laptop seen in the video subscribes to the data stream and converts it to MIDI notes. The notes then get translated to sound by Ableton Live.
Part of a uni project.
