I am looking for an electronic timing circuit that will detect a phone line pick up (usually a ring voltage of 12v). Once a pick up is detected, the circuit will then start a timer that will trip a relay at the end of the timed period (which connects two points for a instant) then reset and wait again for the next phone line pick up. The timer on this board would be best if it was a variable timer...

I am trying to build the following: An ESP8285 is connected to a LiPo via an LDO (3.3V). A SHORT button press should latch power to the ESP8285/ESP8266. The problem is that the latch circuit is always on, even when the button is pressed. The circuit needs to fixed so that: 1) The short button press latches power to the ESP. (Power usage should then be 0) 2) GPIO16 or another GPIO, can unlatch...
