Strange one this. I am interested in converting an old dial telephone to ring when a proximity sensor is triggered and play a recorded message when the receiver is picked up. I need a way to turn it off when I don't want it, and ideally, it needs to run from a battery power source (not essential). The idea is it sits on a shelf and when someone comes into the room, it rings when a motion sens...

we need embaded developer to design pcb and programme to exuecut our project whis works on micro controller.
We have a Hall effect Water meter that we’re connecting to an ESP32 to measure total volume. We’d like to find a way to count pulses offline so we can use the ESP32 to periodically read values from the meter rather than having to count each pulse. We require someone to find a cost effective way to achieve this function.

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...
