the naked espresso

A unique product demonstration that re-engineered the Breville Dual Boiler™ to lay bare the consistency of its commercial grade features through a visualisation of live data and art.
The invention is a world’s first in the kitchen appliance industry. During the process of making each espresso the machine’s data is displayed in real-time, showcasing the accuracy of its internal science and creating a one of a kind art that reflects the individual personality of each espresso.
Each unique piece of art was printed onto the espresso cup with a summary of the hidden science used to make that espresso with all of the artwork then available to download via a unique code.

THE INSPIRATION
A Processing application was developed in order to graphically display the temperature, flow rate, pressure and steam in real time. The animation speed, number of shapes, rotation and position were carefully connected with the machine's behaviour during the brewing process.The design of the artwork was inspired by the generative art movement and artists such as Casey Reas and Joshua Davis.

THE TECHNOLOGY
The BES900 espresso machine was hacked to interface with Arduino and by doing this we were able to output both analogue and digital signals from the Dual Boiler espresso machine.These outputs included:• Two flow meters allowing us to access the espresso flow rate through the group head.• A steam LED to indicate when the steamer was activated on the machine• Three different NTC temperature sensors covering the espresso boiler, steam boiler and group head.We also integrated a pressure transmitter to display water pressure during the important ‘Pre-infusion’ and ‘Extraction’ phases.These signals were converted from voltage to the relevant units and were displayed through a processing application. All electronic components were carefully incorporated into the machine to make it a self-contained and portable unit.The speed of the generative art animation is based on a careful combination of the pressure and flow rate, with the colour palette, frequency and variety of shapes created all based on the temperature and steam used to make the espresso.
