I posted a couple of weeks ago about making a case for my iPod shuffle, which got some good responses. Thats an ongoing project which I might do over the holidays, perhaps even for my A-Level design project if I deem it to be a good enough idea. This idea is different. Naim made a bit of kit called the iSupply (a review of which is at MacUser). Step dad (owner of a 40GB 3G iPod) bought one and the difference IS noticable (much to my surprise). I know that the shuffle has much less sophisticated kit in it (appart from anything due to space restrictions), however I'm wondering whether I could make such a power supply for it. Even if its not going to affect sound quality, a dock style charger without the cost of an official "apple" unit would be great. Hell, while I'm at it I could even give it phono outs too, for my personal convinience! I reckon I could use some pretty generic parts of the base, a little project box from maplins would do, with one of those panel mounted female USB sockets you get on front of cases (had a pair of those hanging around for yonks now) might do the trick for the interface. The other advantage of these is the fact they have got the pins wired up AND labeled... an added plus which means I wouldn't have to mess with a USB cable to get the right pins. I there's also the possibiliy to have a USB out to connect to my PC, but I'm not sure whether that'd be worth it. I may as well take it out the docking station and go over to my PC, plug in and sync really, and simply have the docking station attached to my hifi. All I'm wondering is whether I'd be able to get an audio out from the male USB connector on the bottom, or whether I'd have to have a wire going to the headphone socket. I've done a little research and come up with some relevant articles: http://www.i-hacked.com/content/view/111/94/ http://www.hackaday.com/entry/1234000700034044/ http://www.ipoditude.com/archives/2005/02/hidden_features.php http://www.chipmunk.nl/ipod/ipodshuffle.html Any comments/ideas are welcome!
