Collaborate Disseminate
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 …read more Continue reading Arduino MKR Makes Nespresso Monitoring Easy
Caffeine fuels the hacker, and there are plenty of options to get it into your system, from guzzling energy drinks to chewing instant coffee pellets. But let’s take a nice cup of coffee as input source, which itself can be prepared in many ways using all kinds of techniques. In …read more

[Rulof Maker] is a master at making things from salvaged parts, and being an Italian lover of espresso coffee, this time he’s made an espresso machine. The parts in question are a piston and cylinder from an old motorbike, believe it or not, and parts from an IKEA lamp.
Why the piston and cylinder? For those not familiar with espresso machines, they work by forcing pressurized, almost boiling water through ground coffee. He therefore puts the water in the piston cylinder, and levers the piston down onto it, forcing the water out the bottom of the cylinder and through the …read more

To keep hackers fueled and hacking, why not hack a coffee maker into a coffee brewing robot? [Carter Hurd] and [David Frank] did just that at The Ohio State’s Hack OHI/O 24 hour Hackathon. They even won the “Best Hardware Hack”. The video below shows it in action but the guys sent us some extra details on how it’s made.
To give it a voice they put Alexa on a Raspberry Pi. Using an audio splitter they have the voice go both to a speaker and to an Arduino. The Arduino then uses the amplitude of the audio signal’s positive …read more

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 …read more
