Temperature Controller to Automate Brewing, RIMS, HERMS

by Daniel on March 19, 2014

All grain home brewers looking to increase efficiency and save time and effort on brew day are in for a treat.  The STC-1000 temperature controller that many of you may have used for the keezer project I posted in the past can now also be used for controlling temperatures through step mashes when using a HERMS or RIMS type system, and at a low cost, which we all love!  Thanks to reverse engineering and a programmer who put together some open source coding, modifying the STC-1000 to automate your brew day is within reach.  However, this project is not for the faint of heart, and requires a solid knowledge of hardware & electronics.  If you’re up for it, here are the related links to check it out:

I have one of these it’s hacked to be a fermentation NOT mash controller.
Time increments are in hours not the minuets needed for mash control.
Mat the developer was/is working on the possibility of adapting the code and adding a PID algorithm, which is really needed to avoid temperature overshoot. So far as I know this hack is not yet available.
