Brasilia Espresso Machine PID Upgrade Brews Prefect Cup of Energy

Coffee, making and hacking addictions are just bound to get out of control. So did [Rhys Goodwin’s] coffee maker hack. What started as a little restoration project of a second-hand coffee machine resulted in a complete upgrade to state of the art coffee brewing technology.

The Brasilia Lady comes with a 300 ml brass boiler, a pump and four buttons for power, coffee, hot water and steam. A 3-way AC solenoid valve, wired directly to the buttons, selects one of the three functions, while a temperamental bimetal switch keeps the boiler roughly between almost there and way too hot.

To reduce the temperature swing, [Rhys] decided to add a PID control loop, and on the way, an OLED display, too. He designed a little shield for the Arduino Nano, that interfaces with the present hardware through solid state relays. Two thermocouples measure the temperature of the boiler and group head while a thermal cut-off fuse protects the machine from overheating in case of a malfunction.

Also, the Lady’s makeup received a complete overhaul, starting with a fresh powder coating. A sealed enclosure along with a polished top panel for the OLED display were machined from aluminum. [Rhys] also added an external water tank that is connected to the machine through shiny, custom lathed tube fittings. Before the water enters the boiler, it passes through a custom preheater, to avoid cold water from entering the boiler directly. Not only does the result look fantastic, it also offers a lot more control over the temperature and the amount of water extracted, resulting in a perfect brew every time. Enjoy [Rhys’s] video where he explains his build:

Two steampunk espresso machines running on Arduino Mega

There’s a team of designers based in Korea who are passionate about coffee machines. Their name is Vidastech and recently shared with us two new hand-assembled machines prototyped  with Arduino Mega called Hexagon and Revolucion.

An Arduino-enhanced espresso machine: the “Naked Espresso”

Reborn is an australian digital creative agency whose mission is to design smart and innovative ideas.
Among their works, a very nice one regards a hack consisting in the re-engineering of a sofisticated espresso machine, to show its peculiar features in the process of coffee making.
By means of an Arduino board, the team can collect real-time information such as flow rate, temperature and pressure; then, a Processing sketch graphically presents this data to the user in an artistic fashion.
Finally, each cup of coffee made this way is decorated with an artwork summarizing this information in its own “personal identity”.
More information can be found here.

Text-Enabled Espresso Machine Prints Your Number on Foam

Get a personalized messages, order number or sponsor a coffee to the cute guy in the coffee shop with your number. Now the Arduino style!

We made the Textspresso machine to show off our cloud texting technology. It’s a robotic coffee machine. It utilized java script, 3 arduino microcontrollers, a couple servos, an ikea cupboard, and about 100 other pieces. We think it’s great. We’re open sourcing the plans in the coming weeks.

TextSpresso machine brews caffeinated goodness via text messaging (video)

The folks at Zipwhip may have unwittingly discovered a new business model. While the company is primarily focused on cloud messaging services, it's recently created an espresso maker that allows employees to whip up custom brews from the comfort of their mobile phone. Known as TextSpresso, it's based on the Jura Impressa XS90, but unlike the retail model, the machine accepts orders via SMS. As if that weren't enough, it's part of a larger system that's capable of printing employee names onto the foam (using edible ink) and then placing the drink onto a warming tray. TextSpresso is very much a custom job, but if you'd like an inside peek of the system -- complete with servo motors, an Arduino microcontroller and a retro-fitted Canon printer -- be sure to hop the break and dream of what could be.
