This WiFi-connected video call doorbell uses the Google Duo browser-based video chat app, plus a Raspberry Pi 3 and some upcycled electronics enclosures. We caught up with Martin Mander to find out how's it made.
"You’ll also find a Pimoroni pHAT BEAT board in there to handle audio (so the delivery person can hear what you’re saying back to them), plus a Pico HAT Hacker to make the output from the Pi’s GPIO pins more accessible."
The Pi runs in headless mode and when someone rings the doorbell, it starts a video chat on your phone so you can see who’s at the door, even when you’re not at home – or, as Martin puts it, “trapped under the cat”.
