Are you building this for a blind person? Just curious.

Hi,

I am trying to design an audible/visual indicator that beeps every 5
minutes when a light switch is turned on.

The complete circuit has to fit behind a light switch plate and so a
transformer cannot be used.

Any ideas or pointers would be really useful.

Thanks.
