Silvia PIC controlled PID looped Espresso Machine

Last night I rebuilt my ECM Giotto with a new boiler. I’ve seen PID controlled machines before, but today I stumbled across this modded Rancillo Silvia. [Tim] replaced the internal brain with a PIC controller, added a NES control pad for input, a VFD display and a custom laser cut acrylic top. He used the PIC to provide PID control and PWM heater control with the usual solid state relays. I was leaning towards using a PIC for PID control myself, but then I scored my Giotto. (The heat exchanger and larger boiler makes it a bit of a moot point, but I’m still tempted to add PID boiler controls.)

    I find the combination to be most pleasing.

    I agree, nothing goes better with a bowl than a cup of coffee. I prefer an XL dunkin donuts blueberry, heavy cream, heavy sugar, shot of espresso.

  8. That is quite intriguing. With my coffee I like some nice Mcvities to dip in. Yumsy yumsy :)
