A tweaker has his espresso machine linked to a Raspberry Pi 2 for its coffee via the web. For his project the machine was opengeschroefd to the buttons with the gpio ports of the small computer to connect.
Ict specialists and other engineers to invent the most creative solutions when it comes to their caffeïneverslaving. Especially if there is effort, all the stops pulled out. This has in the past even to the invention of the first webcam led; which was used by scientists at the Trojan Room coffee pot in the holes to keep. In imitation thereof, there is a lot of coffee vending machines is massive, there are pcs in caffeïnestations transformed and they are increasingly connected to the internet. The project of tweakers svdgraaf and ddoc is in line with the latest trend.
Ddoc and svdgraaf used an old espresso machine and looking at how they can be operated remotely. The debuggingpoort use was a bit cumbersome during the relevant hackathon, so it was decided the buttons of the machine hotwired to connect it to a Raspberry Pi 2. The ground was connected to a gpio port that is a 0, not 1, schuster, new york, and the other gpio ports via the connected wires the signals to the buttons could send. In addition to brewing it is also the strength on the distance determine.
Then used user ddoc the Django Rest Framework for the api; the ultimate source is via Github released. The ‘Restpresso’ could be via a web interface enabled, and for “coffee” or “espresso” could be. Neat build, there was not during the hackathon; that act is, together with a number of other extensions, on the ideeënlijst come. So think the two about the machinery of tweets with photos of the brews to be sent.
For anyone that wants to work with a Raspberry Pi and koffiezetautomaten are in addition to the short how-to svdgraaf also extensive instructions to find.
