This is what your coffee looks like as it is being brewed. The three different art pieces seen above were generated based on data from different parts of a high-end coffee maker. This isn’t a bargain basement single switch drip maker (we reserve those for NES retrofits) but a top-of-the-line espresso machine. And before you cry foul we’ll warn you that the project is a marketing device for the manufacturer. But we still think it’s interesting so read on or jump directly to the video after the break.
We’re unsure if the sensors are normally included in the machine or if they were added during the hack. An Arduino pulls in data about the brew process from two flow meters, a steam indicator LED, and three thermistors. The measured values are sent to a Processing application which turns them into the generative art seen above. What results is a widescreen display that aims to turn your bleary-eyed wait for morning coffee into something interesting.
