The control system for the automated Heat Exchange Recirculating Mash System[1] my brother, my dad, and I are building. We're trying to introduce some repeatability into our home beer brewing experiments. The biggest surprise so far has been just how time-consuming and expensive it is to source and buy food grade materials & equipment that can withstand up to 80 °C. Even with heat-resistent plastics instead of stainless steel, we're still spending over $1000 on this part of the set-up alone. Code is very early stage, but what I have so far is here: http://github.com/paulbaumgart/mash-lauter-control http://github.com/paulbaumgart/mash-lauter-control (mostly I've been working on the electrical components up to this point).
