The Idea

As a computer geek I've allways wanted to be able to telnet into the coffee machine and start coffee production using a command. I've seen this done using arduino:

But after the release of Raspberry Pi, I thaught this would be a nice platform for the project. But the Pi needs an IO controller to control the Coffee machine. I found this python controlled USB IO card that would fit perfectly pyMCU. The components has been ordered. PI 25$, pyMCU 25$, a coffee machine, about 25$. In addition I need some relays, cables and a SDCard. Total cost about 100$.
