Stephen C Phillips recently wrote an article on his blog about streaming music from and Android device to a rPi. (http://blog.scphillips.com/2013/01/using-a-raspberry-pi-with-android-phones-for-media-streaming/)His idea was to connect a rPi to an existing HiFi system to stream music. I wanted a slightly more portable version. I had a USB speaker, the Cubite by Boyng, that I no longer used - it was only USB1.1. That has been ripped apart to be remounted into the case. Its only 3W but has reasonable sound quality for what I am looking for.Now I effectively have a portable WiFi streaming speaker that I can use anywhere in the house.To be honest unless you have a Cubite unit around, or can get one, this won't be of much use. However I have supplied the original SketchUp file so people can play and maybe use it as inspiration for another project.Otherwise: Print out all 3 skins, Remove the supports, Clip in Raspberry Pi, Screw the speaker board into the front two sections, Attach the speakers to the back skin, Screw back skin to top and bottom, Stream music where you have WiFi!
