In episode 2 of this podcast, I attempted to explain to my friend Aaron Bandler the type of fermentation controller that I used for my set up. Then a couple of days later John Beeler reached out and agreed to do the show. John is the creator of the Fermentrack software. The Raspberry Pi based temperature controller forked from BrewPi. I felt our conversation was something I had to share so we are going to take on Fermentrack again today on Homebrewing DIY
