Hello to all,
I love brewing and electronics, but most of all I like things to be good and simple
Currently I'm using a small Biab setup to do my brewings. Recently I've done some brews that required multi-step mashing (I made a very good Duvel-like Belgium strong ale!).
Since I have a temperature controller, I could do this, but of course I needed to lift the bag to prevent burning or scorching the bag or grain on the bottom of my pan.
So I started thinking and designing an automated brewing system.
My list of wishes and requirements were:
* Suited for a one-pot system, inspired by machines like the Speidel Braumeister.
* A self-contained unit. Everything in one box. I don't like the idea of having to drag a pc or laptop to my brewing place, not to mention the risk of spilling beer or wort over it...
* Input for a temperature sensor(s?)
* Outputs for:
a heater (10 - 16 Amp, (in Europe that would be 2300 to over 3000 Watt)
a pump, 230 AC and/or 12 Vdc
* LCD display (I choose a 2 line 16 char display)
* Build-in PID controller for temperature control
* Simply programmable for multi-step mashing (temp. / time )
* Audible alarms to notify the user to fill malt, add hops etc.
I think I've already come quite far with my design, but I appreciate input of likeminded people, like you guys ;-)
My prototype is now also coming together and recently I did a test run. I made a 10 liter batch of beer with a multi-step mashing scheme. At this stage my controller is basically a temperature controller (PID controller) with pump control, but the final version will be programmable so you can use it/adapt it for verious recipes or applications.
The total outline of the controller is now being converted from paper to a C-program for the controller. The hardware works fine and sofar everything looks good I think.
Have a look for yourself on my blog or on YouTube where I posted a 16 minute video on this test brew.
If you don't have time to watch that, my blog summarizes it mostly.
