A Nespresso capsule coffee machine duly appeared on his bench, so it was time to make good on the promise. When he was shown a crowdfunded alarm clock coffee maker, said “just give me an espresso machine and I can do the same”.
Posted in home hacks Tagged Arduino MKR, coffee maker, Nespressoīe careful what you say when you are shown a commercial product that you think you could make yourself, you might find yourself having to make good on your promise. If you do happen to have a Nespresso machine though, perhaps you’d like some help identifying the capsules.
TAILOR TALES PLUS HACK FULL
While the pages of Hackaday are full of coffee machine projects we see surprisingly few pod coffeemakers, perhaps because our readers are a canny bunch who balk at paying a premium for their caffeine. We like this project for its non-invasive simplicity, and we can see that there could be plenty of other similar machines that could benefit from an analagous technique for non-invasive monitoring.
TAILOR TALES PLUS HACK CODE
The coffee data can be saved into a CSV file viewable by a spreadsheet, for which code is provided. It’s important to note how this generation of Arduino is no longer one of the simple boards of old, instead it sports an RTC and SD card alongside its SAMD21 Cortex-M0+ processor so it is perfect for just such a datalogging project. A commodity sound threshold sensor board is hooked up to an Arduino MKR Zero, and this set-up logs coffee consumption. For his Nespresso pod coffee machine, eschewed tearing into the device, and instead chose to monitor the sound it makes. Monitoring an appliance with a microcontroller usually follows a well-worn path of diving inside and finding somewhere in the electrical circuitry that can be connected through some kind of interface to a microcontroller.
