@korttoma I plan to do something like this (quick and dirty with MSpaint). I've ordered all my parts, now just wait.

@korttoma This is a total newb question, but it is all about the power. I've done stuff with Pi's before, but this is my first foray into the arudino world. Everything I've read says to power the ring apart from the Arduino (don't use the 5v pin). I am going to use an Uno and I thought I could get a 9v 2a wart and power the board through the barrel connector, using a regulator jumpered off the wart before the board to step down to 5v. However this is all guess work on my part. I figured people have done this, if I saw a finished product I could figure out the rest myself. Thanks for the help.

@chilump Do you have a picture of your final product (or a wiring schematic)? I just discovered this project and don't want to reinvent the wheel.
