Introduction: StepMash: Open All-grain Brewing Mashing Process Controller
StepMash is an opensource Arduino-based controller that allows you to manage a 5 steps mashing process.
-) From 1 to 5 temperature steps (1 sec to 99 min);
-) NTC temperature sensor;
-) Timeout temperature control;
-) Gas valve and piezo ingniter control relays;

PCB is wire-wrapped.
StepMash is a prototype, I will test it soon.
This is my first post, sorry for hand-drawn schematics (so '80s...).
