In this presentation from the September 29, 2013 session of the Derbycon conference in Louisville, KY, David Schuetz, Senior Consultant with Intrepidus Group, demonstrates the use of the R-Pi as a media center and content server. He devised the project as a way to entertain his children on car trips, now that they’ve graduated from DVDs to their own networked gaming and entertainment devices. The hardware consists of a Linksys WUSB54GC wireless adapter, putting a DLNA server on the R-Pi, and serving content from the Pi to AppleTV.
