I brew my own beer, and I have a big heavy insulated box that sits over the fermenting bucket to keep a steady temperature. I regularly need to lift this insulated box off to view the air lock and see how quick the bubbles are coming through.
What I would like is a little microphone to attach to the air lock and linked to something that could repeat the noise of the bubbles coming through.
It does not need to be wireless, but it needs to be cheap
Any thoughts ?
and NO, I don't want the airlock outside of the box, even if it is the obvious solution.
