I completely ripped off ryan97128 on his design for Nintendo Controller MP3, Version 2.0
and I hear that he got the idea from the all wise Morte_Moya, so I can't take credit for all of their genius. I just wanted to add the convenience and recharge-ability of an Ipod Shuffle (2nd Gen).
I copied ryan97128 exactly on his set up except there was no need for the battery and I am not experienced enough to put in extra LEDs, so no cool blue hue. For how to break into an Ipod Shuffle, there was this
instructable from technochicken which was most helpful.
To avoid redundance, I will assume that you will be able to follow ryan97128 on how to set up the circuit board from the controller and have the Ipod taken apart and ready to go.
Total cost for this project was about $40 for me, the only things I needed to buy were a used Ipod shuffle off eBay and a connector cable for it (you won't be able to use the included stand in my design).
