I don't want to disturb the neighbours! I plan to include a switch so that
the the outside bell can be turned off when not in use. (And anyway, I'm
hardly Mr Popular so the thing won't exactly be ringing off its mountings).

Or does anyone have a better idea.

Or maybe I could use one of these without a waterproof box:

At least the buzzer looks fairly watertight.
