Yesterday we tidied a lot more of the space and hooked up a big button to
open the front door from the workshop.
We want to put something on the buzzer pins so we don’t need a separate
doorbell. It has 12 Volts AC at 50Hz, with probably about 100mA of current
available.
Anyone got any silly ideas for easy things to hook up to it? My current
plan is to use a bridge rectifier and zener diode to feed it into an AVR
and make things react through that.

engineering of the intercom.
Maybe we can do something with that yellow spinning light we have. If it
doesn’t take too much current. That’s about as silly as you can get I would
