    Finally, you can DIY your own espresso machine

    Caffeine lovers take their coffee very seriously and that is most apparent when you dive into the world of espresso machines. To satisfy enthusiasts, an espresso machine needs to provide precise control over temperature, pressure, and flow to enable the perfect pull. But if you’re the type of true aficionado that isn’t satisfied with any consumer off-the-shelf option, then you’ll be interested in the diyPresso One machine.

    The diyPresso One kit costs €1,250.00 (about $1,390) and it isn’t meant to be a budget option. But it is more affordable than many of the high-end machines on the market. And, more importantly, its DIY and hackable nature means that you can tweak it and tinker with it until you have it exactly the way you like it. If you can’t make your perfect cup of espresso with the diyPresso One, then your perfect cup simply doesn’t exist.

    That all starts with the open-source controller and software, which monitor the machine’s various sensors and oversee the brewing process. That controller is built around an Arduino MKR WiFi 1010 board, programmed with the Arduino IDE. The choice to use Arduino was critical, because it lets users easily modify the machine’s behavior through simple sketch changes.

    The rest of the parts are of equally high quality. The enclosure is stainless steel formed into a beautiful minimalist design, with side windows so everyone can see the stunning copper boiler that was custom-made for the diyPresso One. And the machine takes advantage of E61 brewing group components, so users can swap them based on preferences or requirements. 

    Kits are now available on the diyPresso site, but stock is limited.

  • LanderShot is an out-of-this-world espresso machine

    If you think coffee people are opinionated, then you’ve never met an espresso person. There is a lot of art and science that goes into making the perfect little cup of espresso and a good barista will control every factor, from temperature to pressure to pour rate. It isn’t rocket science, but it isn’t far off. So the LanderShot Lunar Espresso Module, a CNC-machined high-tech espresso machine, has a fitting theme.

    This is, at its core, a premium espresso machine that merges designer aesthetics with cutting-edge electronics. The founder of LanderShot, Ted Ciamillo, lives in the state of Washington, but is of Italian descent. He wanted to honor his Italian heritage — and the origin of espresso — so he turned to Arduino.

    Temperature control is crucial when making espresso; heat the water too much and you’ll burn the coffee, but you’ll lose the flavor and strength if you heat it too little. For that reason, the Lunar Espresso Module utilizes PID (proportional-interval-derivative) control for the 1000-watt heater. That ensures that water comes up to temperature quickly without overshooting the target, helping it go from 20 °C to 100 °C in just 180 seconds. A pneumatic lever lets the user increase the pressure to the desired level, with each stroke adding one bar.

    An Arduino Nano Every board controls the heat, monitors temperature and pressure, and displays the results on a small screen offset to the side. “The Nano Every is excellent at performing the several jobs in the machine. We chose it for its low-profile architecture, easy access to the pinouts, robustness and accessible price point. And, of course, we are pleased that the brains of our machine were designed in Italy,” Ciamillo says.

    He adds that the greatest technical challenge was fitting all of the electronic components into the compact machine. While that may be true, we think that he’s selling himself short on the design and CNC work. The milled parts are stunning to look at, and we can only imagine that they’re even more pleasing to touch while pulling a shot.Ready to take your daily coffee to new heights? A limited number of LanderShot Lunar Espresso Module machines are available for pre-order and should ship out in June.

  • Enjoy the ultimate espresso machine on a budget with Gaggiuino

    There are few beverages on this planet that enthusiasts take more seriously than espresso. Aficionados care about and tune everything from steam pressure to bean roasting temperature. But espresso machines that provide both accurate and precise adjustments are very expensive — easily several thousand dollars. Fortunately, you can tackle the Gaggiuino project to upgrade an affordable Gaggia espresso machine to something comparable to a high-end machine.

    Gaggia espresso machines cost less than $500 and they’re quite good for that price point, but they aren’t a match for something like a $6,000 La Marzocco Linea Mini. However, the building blocks are there; Gaggia espresso machines have high-quality parts, they simply lack precision electronic control. Gaggiuino addresses that shortcoming with a handful of affordable components. For around $100 worth of hardware, you can dramatically upgrade your Gaggia Classic or Gaggia Classic Pro to create an exceptional machine.

    The hardware required for the Gaggiuino upgrade includes an Arduino Nano board, a 2.4” Nextion touchscreen LCD, a thermocouple, a solid-state relay (SSR), a pressure sensor, and a dimmer module. A few 3D-printed enclosures and mounts help to secure those components. After performing this upgrade, you’ll get a ton of great features. Those include: steam control, sensor graphs, manual flow control, a descale cycle, an auto shot timer, user profiles, and a nice UI to access and configure everything. Thanks to the new hardware, those functions all operate with great accuracy and precision, so you can dial in your perfect brew and get the same results every morning.
