Of course we all already knew about using popcorn poppers for roasting coffee (which seems to work pretty well, as Jerry and myself can attest to). But what about using a coffee maker to brew your own beer? The article's old (2002), but it seems like a sound way to make very small batches of beer with little effort or equipment. Using cheesecloth instead of a lid and airlock kind of concerns me, but one could avoid contamination of the beer by putting the beer in a fairly closed off area. The article also neglects to mention bottling and carbonating the beer, but that's also a fairly simple step. Since the article advocates letting the beer ferment in a jar, one could add a couple tablespoons of sugar into the beer after it's done fermenting and secure the jar with its lid.
I should add that I found this link while searching for the German man who converted a washing machine (babelfish link, original here) into a computer-controlled brewing machine. If only I had the money, time, and space to make something like that.
