PID controlled popcorn popper coffee roaster


In honor of my espresso machine being fully plumbed in (water supply and drain line!) it’s time for another coffee hack. When I wrote my basic coffee roaster how-to, I seriously thought that I’d never see anyone do this, but [] installed a programmable PID controller on his popper coffee roaster setup. This particular PID can be programmed to ramp the temperature over time to create an actual roasting profile, rather than manually adjusting the set points. The original page was here, but I had to pull it out of the internet archive.

  1. I read “PID” and I thought “A coffee maker controlled by process IDs?”

    This is a cool hack. There ought to be more coffee hacks, then we could use the resulting good coffee to stay awake and make even better coffee hacks, and the cycle repeats.
