Andy travels a lot for his job and he often wonders if his child thinks of “dear old dad.” Andy created a Do-It-Yourself hack modifying a teddy bear to send notifications. When his daughter plays with the bear, it sends him a notification to his phone. Andy hacked an Amazon Dash Button – the very same buttons that I mentioned before for automatically ordering baby formula.
The buttons connect to your Wi-Fi network and send a message when they are pressed. He catches the message using a Raspberry Pi and then creates a notification for his mobile phone.
Maybe as a next step, Andy could add some haptic feedback to the teddy bear so that the bear tells his daughter that he got the notification. This would close the communication loop.
