I got the idea to make this from starring at a bowl mixer at a store just after brewing another batch of beer.
Since I do brew my own beer, I was getting tired of all the waisted time just standing around and stirring. So I came
up with this! Now all the boring work is left to the machine! And it's multi-functional. I designed the boom arm to
tilt up at 90deg so that the horizontal rotational motion could be translated to a vertical up/down motion for steeping!
So it can stir the beer and dunk the grains bag. It's good for cooking stew and soup too!
