Raspberry Pi AirPlay setup

It took a while to find a reliable ‘set it and leave it’ configuration for my Pi-powered AirPlay network. Here’s the config I settled on, with thanks to Ray Wenderlich and Pi My Life Up.

Update: I’m no longer using this config because Shairport doesn’t support AirPlay 2 for multi-room synchronisation. A set of second-hand AirPort Expresses have taken up the role with no problems to report.

Human eyes can’t see the infrared light produced by remote controls. However, your iPhone can. As long as you have an iPhone 4 or newer, your front-facing ‘FaceTime’ camera can see IR light, if you’re still rocking an 3GS or older then you can use your rear facing camera. If you have another smartphone, give it a try. I can’t guarantee that it’ll work with individual models, but it’s worth a shot.

Is Google Glass Doomed before it even hits the general public?

Google has been making quite a bit of fuss over its precious Google Glass – trying to integrate it in to all of their services (presumably Reader wasn’t compatible) before anyone has even got it. They have their Explorer Program, which was supposed to get Glass into the hands of ordinary people doing extreme sports, etc.

Unfortunately, it appears that this wasn’t entirely successful. Many of the people who have started to receive the Explorer Project invites seem to be celebrities and other Twitter uses with high numbers of followers. Now clearly this helps Google with the marketing of Glass for when it is (presumably) publicly released. Celebs flashing their new gadgets, glad to be a part of another exclusive club.

But is this right? Should the invites be handed out on a basis of how many people will recognize you? And then there’s the other problem. Will it work? Will the celebs make...
