This tutorial will turn your Raspberry PI into a simple Bluetooth audio receiver, which plays music through connected speakers. It's like a regular car audio system, but it can be used anywhere and it's a good value.

This is a quick-and-dirty guide to setting up a Raspberry Pi as a "router on a stick" to PrivateInternetAccess VPN.
Install Raspbian Jessie (2016-05-27-raspbian-jessie.img) to your Pi's sdcard.
Use the Raspberry Pi Configuration tool or sudo raspi-config to:

Last year, when visiting my family back home in Holland, I also stopped by my grand-parents. My grand-father, now 93 years old, had always been a very active man. However, during the presceding couple of months, he'd gone almost completely blind and now spent his days sitting in a chair.
