So after viewing many posts and seeing other people's IR Pens, I started looking around for something to serve as my container. I came across an old 1gb ipod shuffle. I thought this would make a perfect case for an IR pen, the switch could be the play/pause button, and it already has a rechargeable battery. I wanted to get some thoughts on this regarding opening the shuffle, battery usage, and random thoughts before I dove into this project. A photo of the First Gen Ipod shuffle can be found here... http://upload.wikimedia.org/wikipedia/commons/c/c8/Ipod_Shuffle_rotated_transparent.png
