Title
Description
Would you like to stroll into the office to your own dramatic theme music? We can arrive in style with an epic score. Learn how to use RubyMotion, a Raspberry Pi and iBeacon Technology to play the Imperial March when the CEO walks in. The ability for mobile devices to detect their proximity to beacons is relatively new. We will learn how they work, the common gotchas, and how to integrate with a bigger system. Let's build something fun with Ruby and Beacons. Plus, who doesn't want an awesome theme song? Help us caption & translate this video! http://amara.org/v/FixE/

Summary
Markdown supported
In the video titled 'Epic Intro Music: BLE Beacons and Ruby,' Christopher Sexton introduces an innovative way to integrate BLE (Bluetooth Low Energy) beacons with a mobile app and Raspberry Pi to create a fun music-playing experience that announces when people enter the office. The session, delivered at RubyConf 2014, focuses on the mechanics of beacons, the emotional backdrop of creating thematic entrance music, and practical implementations of the technology. The key points discussed are as follows: - **Introduction to the Concept**: Christopher discusses the idea of playing personalized music when different personnel enter the office. He humorously reflects on what theme song would suit him, settling on the well-known 'Rick Roll.' - **Need for Components**: The system requires three main components: - **Speakers** to play the music, - **A Mobile App** to detect the beacons, - **BLE Beacons** for proximity detection. - **Understanding BLE Beacons**: He explains that BLE beacons operate as simple broadcasting devices that continuously send out identifiers. Though typically identified with Apple’s iBeacon specification, he mentions AltBeacon as a more open alternative created by his company. - **System Architecture**: The talk walks through a whiteboard session illustrating the architecture, where beacons send identifiers to a mobile app, prompting a Raspberry Pi server to play music when someone enters. - **Implementation in Practice**: Christopher demonstrates building the entire system on a Raspberry Pi, detailing how it broadcasts identifiers and plays music using a Sinatra app. - **Misconceptions about Beacons**: Several misconceptions surrounding beacon technology are addressed: - Beacons do not deliver content; they broadcast identifiers. - They do not track users or know when they are detected. - Signal strength can only provide approximate distance measurements, which can fluctuate. - **User Interaction & Opt-in Mechanism**: He explains that users need to opt-in for notifications, thereby maintaining privacy regarding tracking. In conclusion, the integration of Raspberry Pi and BLE beacons enables exciting applications, such as playing themed music in creative workplace environments. The talk combines technical knowledge with light-hearted anecdotes, ultimately revealing that while technology can be complex, it can also be fun and engaging.
