Some household devices tend to act up. My Nespresso Essenzia Mini decided to misbehave, so I punished it. Buying another one is not enough, because it would mean lazy retirement days, oh no! It must work until eternity!
The machine itself is really simple. The PCB is small and elegant, so I decided to reverse-engineer it and rewrite the firmware from scratch. It has a PIC16 MCU, so it won't be hard.
