Very slick! Much more elegant than the old stereo reciver/laptop setup.

For my speaker, I hang it from a spring so that it gets pulled down to use.

Been there, done that. Tried a phone as well as an iPad and a PC, wired link and Bluetooth link. Yes, we made all of those work, but the usability for demonstration/teaching purposes was not what I wanted, and it was after trying the PC/iPhone/iPad/Bluetooth idea that I decided to build the unit in this thread.
