Senseo coffee makers are automated brewers that use coffee pods. [Ronald] had one, but wasn’t satisfied with the quality of the coffee it produced. His solution was to hack it apart and build his own automatic coffee machine with the innards.
The coffee brewing part of the system is controlled by an ATmega8. This reads the temperature using the NTC sensor from the original machine and actuates the various parts of the Senseo machine, and the added grinder. The timing was all done by trial and error, optimizing for the best cup of coffee.
Keeping with the trend of adding Raspberry Pis to everything, [Ronald] connected one to this build for remote control. He runs a very hacked version of LCD2USB which deals with communicating with the RPi. An Apache web server hosts a PHP script to provide a user interface, which runs a C program to tell the system to start brewing.
Unfortunately, [Ronald] didn’t give us a link to his web interface, so we can’t remotely brew him coffee. However he did provide all of the source for the project in his write up.
