We made one using the fan and a couple rare earth magnets. We glued the washer to the fan and never even had to glue the magnets down. Initially we did it for placement, but it worked so well we never messed with it. Then we mounted it into a little project box. Couldn't be happier with it!
We brewed this this past weekend and used a bit of coriander because we heard that that imparts orange flavor as well. We also used some zest. Anyone else tried the coriander? We will be bottling soon. So we'll know soon if it was a success!
