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, and also dumps status information over the serial port.

Update 1: I’ve ordered parts for a permanent install on protoboard, after I finish the install, I’ll update this post with build instructions and details. I will also provide a link to a mouser project where you can order most of the parts in one place.

Update 3: Everything is assembled and functional, and I made an aluminum case thing for the LCD and rotary encoder. Photos to come soon. (8/25/10)

Update 4: ZonCoffee .2 is released! See the release page to download the sketch and to see additional hardware information. (1/4/11)

This post is one of a series of posts regarding mods I have done to my EC155
