The last few years I built some controllers mostly based on #ESP using C++ open source projects.
I thought it would be nice to list them for those interested in #homebrew and #beer making.
I like the brew process but also the design and building steps of electronic equipment
1: brew controller designed by a fellow beer brewer. Controls temperature and steps during mashing. Touch screen and a control of the indcution cooker
2: a simple temperature measure and time (as backup when I remotely brew)
3: iSpindle to measure the progression in the alcohol during the fermentation
Now replaced by a device that utilizes bluetooth and qmtt and more because it resides inside a metal container
4: brewpiless, a controller for the fermentation chamber. It switches the cooling and heating to maintain a controlled environment
Below some prototypes, more to follow if there is interest with some links
