If you are getting tired of your plain old doorbell that just goes ding dong when someone presses the button why not jazz it up with a bit of electronics. Nicholas Skinner has done just that with his Doorbell System.
“Features:
- Sense Bell Press – Allowing for triggering of other events on press, such as additional remote ringers in other parts of the house, computer popup notification and possibly cameras / camera display (e.g. via scart triggering on TV) etc in the future.
- Disable Bell Ringer – From either a remote physical switch or PC (for periods when we do not want to be disturbed by doorstep salesmen).
- Ring Bell – Allowing the bell to keep ringing for a certain minimum duration even if the button is just pressed quickly to save missing callers who do not hold in the button for an adequate duration.”
