Hello everyone! I came across some nice software to make a fast video / 2-way audio doorbell with a Raspberry Pi, and found a way to fit all the components in a small case.
I will show you how to build it, including how to make push notifications work when you press the button.
The hardware build requires a bit of drilling and soldering. The software portion is pretty straightforward with no coding required (unless you want to customize the sample programs). But it does require a Mac and XCode. See the following video that documents all the steps.
