EC155 PID with Arduino
This is a build log of my PID modification to my DeLonghi EC155 espresso machine. Currently, the machine uses an Arduino to drive a solid-state relay controlling the heating coil. The Arduino displays mode and temperature on a serial lcd,…
Depressurizing the EC155 Portafilter
The DeLonghi EC155 is a fairly well-built consumer pump espresso machine. It ships with a pressurized portafilter of a non-standard diameter, so finding a non-pressurized replacement is challenging. Instead of purchasing a new portafilter, depressurizing the EC-155’s portafilter is extremely…
