Fun tutorial using WebRTC to capture your photo and then send it to someone using SMS messaging via Twilio’s API.

Bzzzt! Opening the door using WebSockets and a Raspberry Pi


Alex Barlow, MadeByMany
Apr 1 2015
Despite the presence of a zombie finger in this post, and it’s publication on April Fool’s Day, I don’t believe this is futuristic apocalyptic science. It’s a tutorial on hacking a door entry button by using a Pi and WebSockets to tell the zombie finger to press the button.

Galeal Zino, NextBlitz
Mar 27 2015
This post, which is mainly about a chat app called Tivia, also makes the interesting point that the relative ease of integrating WebRTC means that you can focus first on the overall experience of your application, and then add in WebRTC later. Agree/Disagree?
