What do I have to text to make a mug appear?

yea, good point - what if we have many people in the office and everyone is using his own cup ? :)

pic recognition + robot arm ?

Admit it, you just needed an excuse for the company to buy a nice espresso machine for the office :)

It was looking pretty good until that last picture.

That mains wiring is plain unsafe and almost criminal...

Their power hookup looks a bit dangerous: http://zipwhip.files.wordpress.com/2013/02/raspiblog2.jpg

Yeah, that should be sheathed. Let's hope no-one texts for a coffee and starts a fire instead!

Agree, at least put a bit of heat-shrink tubing on that. Though, I'll admit to having done worse.

And ~20-40 hours of hardware hacking.

Nice, but what happens if two people text the machine at the same time :P

I'd assume it would work just like a printer que.

I'd assume it works just like pressing a button while the coffemaker's brewing a cup. You'll probably have to resend the text.

Does anyone know if this sort of hack also exist / is possible for a Philips Senseo machine?

I don't see why not, but you would need a machine with a built in pod dispenser to make coffee "unattended" The machine in the article grinds coffee beans.

This is my Raspberry Pi-powered espresso machine dashboard: http://zentrale1.com/~an/coffee/ I use this with an iPad standing next to the machine to check that the temperature is okay before pulling a shot. The temperature controller is implemented with an Arduino board.

Nice, here is the current progress of my Silvia / PID monitoring: http://i.imgur.com/mis4L.png.

I'm using Arduino + TC4 shield for PID and interfacing w/ thermocouples, SSR, and opto-isolators (for front panel switch sensing). Serial to RasPi to web sockets for the frontend.
