In the world of technology and consumer electronics, the user interface (UI) plays a pivotal role in determining how much we enjoy using our devices. This assertion holds true for many users, including a passionate coffee enthusiast known as [Janne]. He owns an espresso machinea model that, despite its popularity, fell short of his expectations in terms of usability due to its default controls. In true hacker fashion, [Janne] decided to take matters into his own hands, transforming his espresso machine into a custom creation to better suit his needs.

Enter the Flair 58, an innovative manual espresso machine that originally boasted a minimalist design, featuring few moving parts and no electronics in its standard configuration. While it offered an optional preheater, [Janne] felt that this addition lacked the finesse he desired. Thus, he embarked on a mission to enhance his espresso-making setup, integrating a sleek touchscreen display that controls a custom heater board with closed-loop temperature control. This enhancement also allows for the connection of an external scale, ensuring precise pour measurementsan essential feature for any serious coffee aficionado.

While there have been various coffee maker hacks in the past, [Janne]'s transformation of the Flair 58 truly stands out. His modifications not only add practicality but also aesthetic appeal, filling a void left by the machine's original design.

To successfully incorporate the two custom printed circuit boards (PCBs) and the touchscreen into the Flair 58, [Janne] undertook the meticulous task of modifying the machines frame. The machines elegant, swooping curves presented a unique challenge; however, rather than opting for a bulky external enclosure, he ingeniously crafted the PCBs to fit seamlessly within the existing structure of the device. The result is a beautifully integrated solution that enhances usability without compromising the machine's original design.

For those interested in exploring his impressive work further, [Janne] invites everyone to visit his website, where they can admire this beautiful modification along with his other creative projects, including one centered on laser fault injection. Notably, all hardware and software components for this innovative espresso machine upgrade are freely available on his site. For anyone looking to elevate their coffee-making experience, this is an opportunity you won't want to miss.
