People keep warning that Skynet and the great robot uprising is not that far away, what with all this recent AI and machine-learning malarky getting all the attention lately. But we think going straight for a terminator robot army is not a very smart approach, not least due to a lack of subtlety. We think that it’s a much better bet to take over the world one home appliance at a time, and this AI Powered coffee maker might just well be part of that master plan.
[Mark Smith] has taken a standard semi-auto espresso maker and jazzed it up a bit, with a sweet bar graph nixie tube the only obvious addition, at least from the front of the unit. Inside, a Raspberry Pi Zero sits atop his own nixie tube hat and associated power supply. The whole assembly is dropped into a 3D printed case and lives snuggled up to the water pump.
The Pi is running a web application written with the excellent Flask framework, and also an additional control application written in python. This allows the user to connect to the machine via Ethernet and see its status. The smarts are in the form of a simple self-grading machine learning algorithm, that takes a time series as an input (in this case when you take your shots of espresso) and after a few weeks of data, is able to make a reasonable prediction as to when you might want it in the future. It then automatically heats up in time for you to use the machine, when you usually do, then cools back down to save energy. No more pointless wandering around to see if the machine is hot enough yet – as you can just check the web page and see from the comfort of your desk.
But that’s not all [Mark] has done. He also improved the temperature control of the water boiler, and added an interlock that prevents the machine from producing a shot until the water temperature is just so. Water level is indicated by the glorious bar graph nixie tube, which also serves a few other user indication duties when appropriate. All in all a pretty sweet build, but we do add a word of caution: If your toaster starts making an unreasonable number of offers of toasted teacakes, give it a wide berth.
While skimming, I saw “nixie tube hat” and got excited, but my balloon deflated when I remembered what ‘h’ ‘a’ ‘t’ means in the Pi-osphere.
Oh well.
there’s a much handier idea based on the esp8266 it features a PID as well as features like brewdetection and other nice things.

also the parts used are simple as a SSD relay a temperature sensor DS18B20 and an esp.
I was at least expecting connectivity with your smart watch, being able to link the current stress levels to the amount of beans in your shot
Caffine levels measured through ability to vibrate through a metal plate.
In the Battlestar Galactica series reboot, I’m sure they followed a similar evolution.
The chrome plated Cylon soldiers were referred to as “toasters”.
For a while, one could buy a BSG toaster on the web.
That brand name though…
I’d be worried about it serving rancid coffee.
Not every company has an English name. Not everyone on this planet has English as mother tongue. Or a name that sounds great to your sensitive ears. Rancilio was founded by Roberto of the same name in Italy. https://en.wikipedia.org/wiki/Rancilio
Some American product names sound wierd if you actually read them. Birds Eye foods?
Yummy!
standard semi-auto espresso maker?? Might want to read up a little on this lady (Silvia), and fix that ;)
Exactly. This is a semi-professional espresso machine from Italy, not a semi-whatever Nespresso toy.
Yikes actually you might want to do some googling yourself. This machine (rancilio silvia) is classified as a semi-automatic machine, since it pushes the water at a consistent temperature and pressure, opposed to an automatic machine which does the same and also pushes the correct amount of water, contrasted with a manual/lever machine which you must produce the pressure and amount yourself. (Not to mention a super automatic which will grind beans and prepare the coffee puck before brewing)
Why do I always get mental images of Talkie Toaster, whenever I read of anyone putting AI into household appliances.
You did see the link at the bottom of article?
The intro paragraph reminded me of https://what-if.xkcd.com/5/
Though recent developments at Boston Dynamics leads me to fear that they may have solved the “striding triumphantly on an unstable mound of human skulls” issue.
Thanks for the link to that! The ending made me think robots would have a different term for nuclear strategy. In lieu of Mutually Assured Destruction, they’d have Mutually Assured Reboot or Mutually Assured Shorts (which I like the sound of better).
We had a high tech coffee maker at work. Full of motors and transducers and it had a display etc. I had a french press. Guess who was never without coffee.
We also have a high tech coffee maker at work…
I am on a first name basis with its Tech Support.
Also reminding me of a scene from Buffy it goes “We’re drawing up a plan for world domination… https://getyarn.io/yarn-clip/4521dbb0-07ae-4e7a-8694-05cba9f51740
Well if it doesn’t put a hefty shot of rum in my coffee it doesn’t know me well enough.
