I suggested using his phone but he's only taking a basic phone with him but needs access to his bank account to make money transfers.
Tell him to take his smartphone, he'll add too many complications and questions at border security..
Next time he asks, perhaps throw a shoe at him instead
Nothing worse than someone trying to feed you the proper inputs so that you will eventually just say what they want to hear. It can be infuriating.
Do you need a DAC for a Pi3? It already has a 3.5mm jack.
bit overkill wouldn't it? unless you were to use the camera as well?
Overkill is my middle name - especially when it comes to designing tech solutions.
Our last doorbell kept desyncing with the base unit inside so we just took the doorbell off... But my idea was to use a webcam pointing at the front door, write a simple motion detection program that captured when somebody moved in front of the door, and send network packets to notify me on my desktop/phone/etc. It also means you can't break/lose the doorbell, it can't desync, and the person at the door doesn't have to actually press it.
