So, this question might sound a bit silly at first glance (no, I know, it sounds flat out insane), but not all that silly at second.
I have heard once about a guy who transformed some (presumably old-ish) washing machine into his own personal home-brewing apparatus. It is quite some idea if you think about it. Washing machine can easily solve most issues people have with homebrewing. It can carefully control and adjust temperature throughout the long and complicated process of brewing, it can stir, it can pump in fresh water.
Main question is, how to control washing machine to do what I want it to do. Most automatic washing machines already have some controllers, but I don't see much chance in trying to simply reprogram them (Am I wrong?). Arduino seems like best choice for its simplicity and expandability. However I am still fairly new to Arduino and have trouble imagining how would connecting everything from washing machine (motor, pump, maybe water and temperature sensors) to Arduino actually look like.
So is it even possible? Are there any projects to "bounce of"? (I couldn't find any, but maybe I looked for wrong projects) Should I expect any major problems?
