Main controller is ATtiny85-20s which is connected with serial port to LTE IC - quectel ec200u. Owner's number can be hardcoded in attiny's flash to call the owner. there is 1 push button connector to attiny which can be programmed as you want. Mic -4013SMTis placed on pcb and for speaker 8ohm 0.5W will be soldered on pcb with wires. Sim connector is 6 pin. this is my first project on hackaday.io and have not tested it physically but i have worked with components in another projects so it is possible in theory. i hope you like it and give suggestions to improve it. in future we will try to make it physically.
This is an amazing idea.
