I was wondering if anyone had a simple circuit for the typical teenager
which does not realize how long he is on the phone.
Basically once a number is dialled the timer starts timing and after eg.
29min beeps once then after 30min drops the call ..... Something like that
???
If anyone's got any ideas I am keen to hear them ... Thanks.
