Title
Description
Look, I know you love your sprinkler timer, with its endearing little dials and simple, easy-to-use interface, and its killer dot-matrix LCD. We thought we could do better, and we thought Ruby could help us. With the awesomeness of things like the Raspberry Pi and maybe a little Arduino, who's to say I can't use Ruby to water my lawn, remind me to fertilize, or let me know where I could save a little water? We'll take you on a quick tour of the automated sprinkler system world and the problems it has, and how we're solving them with Ruby, Raspberry Pi, and about 24V of DC power. We promise not to electrocute you, but we can't guarantee you won't get a little bit wet. Help us caption & translate this video! http://amara.org/v/FGbP/

Summary
Markdown supported
In this presentation titled 'Ruby In My Yard!' delivered by Corey Woodcox at MountainWest RubyConf 2013, he explores home automation through the integration of Ruby, Raspberry Pi, and Arduino technology, particularly focusing on creating an automated sprinkler system. Corey begins by sharing his background in software development, emphasizing the importance of automation and how it can simplify everyday tasks. Key points discussed include: - **Home Automation Concept**: Corey expresses his frustration with outdated home automation devices, using his old sprinkler timer as an example of inefficient technology that still requires manual operation. - **Simplifying the Process**: Highlighting the desire to streamline operations, Corey discusses how home automation is about avoiding repetitive actions and making systems easier to use, referencing popular gadgets like the Nest thermostat. - **DIY Sprinkler System**: The main focus of the talk is on building a cost-effective and efficient sprinkler system that can handle various watering schedules without user intervention. Corey explains the mechanics of a 24V solenoid and how it can replace his clunky old timer. - **Technology Choice**: He contrasts the use of Arduino and Raspberry Pi, explaining his preference for the Raspberry Pi due to its broader capabilities and ease of programming with Ruby. - **Live Demonstration**: Corey attempts a live demonstration to show the communication between the Raspberry Pi and the sprinkler valves. After some troubleshooting, he successfully opens and closes the valves, showcasing the functionality of his system. - **Components and Resources**: He shares details about various components used in his setup, like solid-state relays and GPIO pins, and encourages attendees to explore available resources and materials. Corey closes by highlighting the immense potential for automation in everyday tasks and encourages continuous exploration of DIY solutions using programming and technology to enhance convenience and efficiency in our lives.
