Life seems to be stacking things against me recently, limited time, back pain, and lack of space. I love brewing but I need to do smaller batches that are faster start to finish. Now I need some input.
To that end, I am going to try BIAB, a much maligned and often misunderstood technique. Since I'm a geek, and happen to have an extra arduino or two, I've come up with a unique way of doing BIAB.
I am planning on using my old extract brewing pot to do 2 gallon BIAB batches. I am going to install a thermowell in the middle of the pot and insulate the pot with some leftover Reflectrix that I have (http://www.homedepot.com/Building-M...splay?langId=-1&storeId=10051&catalogId=10053). It is great stuff and is easy to attach with some aluminum tape. I will be using a 5 gallon paint strainer bag for my bag.
The arduino comes into the picture in controlling my mash temperatures. I am thinking about using the widely available PID algorithim to control a servo which would in turn move the gas knob on my stove (either through a rod setup or some sort of gear). I would use my aquarium pump setup to keep the wort moving in the pot.
Now I'm not even sure this step is necessary with proper insulation but it sounds like a fun project. Any ideas?
UPDATE: I've been looking at this code for and Arduino Espresso System: http://www.arduino.cc/playground/Main/BarebonesPIDForEspresso
Couldn't the PID output be converted to proportional servo movement?
