TAILIEUCHUNG - Smart Home Automation with Linux- Part 11

Smart Home Automation with Linux- P11:I will end on a note of carefree abandon—learn to steal! Once you’ve learned the pieces of the puzzle and how to combine them, there is very little new to invent. Every new idea you discover is a mere permutation of the old ideas. And ideas are free! Every cool feature discussed on TV shows or presented in the brochures or web sites of commercial HA companies can be taken, adapted, and implemented with the information presented here using very little effort | CHAPTER 2 APPLIANCE HACKING Note All devices should be grounded accordingly not as shown in the figures for clarity. Conclusion In the same way you can build complex and evocative systems using a couple of well-chosen pieces of hardware so can you build smart automation tools with a minimum of effort. By using alternate input devices such as pressure mats and joysticks you can change the way you interface with your home. By adding alternate output devices perhaps powered by old game consoles you supply visuals to areas previously inaccessible to full-scale desktop PCs. And the introduction of robots and computerized welcome mats adds a level of previously unknown of coolness to your home. 83 C H A P T E R 3 Media Systems Incorporating the TV and the HiFi The most visible part in any home environment is the media system. Ever since real fireplaces fell out of fashion the TV or stereo system has become the focal point of most living rooms. They are also the devices with which we spend the most time interacting. It is therefore essential you understand the possibilities of these devices. As with all consumer electronics the feature sets and prices change on a daily basis. Therefore I ll concentrate primarily on the necessary features and inner workings of the machines without detailing specific makes and models since by the time you read this other machines will already be available. The Data Chain The simple act of playing an album changes significantly in the home automation field. Not only is the location of the media itself unconstrained but it s also the place where you can listen to it. This has been exemplified recently with iTunes allowing you to play music on several different computers and with Spotify providing a music-streaming service allowing access to various music tracks from your home PC or If your interest in music is casual or chart-based then these services are often enough. But for many people they have albums in their collection that are
