Beer lovers rejoice! [Mats] has reverse engineered a temperature controller and written new open source firmware for it. This effectively gives all us homebrewers a low cost, open source software ...
The scheme in Figure 1 reduces system acoustic noise by running system fans at their optimum speeds for a given temperature. IC 1 combines ±1°C-accurate temperature measurement of three temperatures ...
This temperature profile is one of the principal reasons why we need a PID controller, which will be able to very accurately follow the required dwells and slopes, while also avoiding big oscillations ...
