I'd like to see some sort of device that would disable the doorbell for
thirty seconds after the button was pressed the first time. I don't know
why people think I'll get to the door faster if they ring the bell a
dozen times instead of once.

All you need is a timing relay of the appropriate voltage that will open
the circuit on application of power and will not make it available to the
button again for whatever interval you set.

Time delay relays can be expensive. For example a 24AG-KRP11 Interval On
relay is almost $80. I suppose I could use an IC to drive an inexpensive
relay but then I'd have to build a power supply. How many milliamps are
available from a doorbell transformer?
