iPod Camera Connector

Well, the iPod camera connector is a lot smarter than I originally thought. After a bunch of poking around with a multimeter, it appears to do the following:

– Pass the USB GND, DATA+, and DATA- signals straight through to the dock connector.
– Bump up the +3.3VDC that the iPod provides on dock pin 18 to +5VDC in order to power the camera / memory card reader that is attached. (This, along with the disk access, explains the horrible battery life experienced when using the reader.)
– Somehow flip pin 21 to a value (10k? — perhaps in the presence of power?) which indicates that a photo adapter is connected. I was unable to establish this value.

Also, the connector is glued shut, so I’m unable to open it without trashing it. I guess I’ll take it back as soon as I get confirmation that the external hard drive memory card reader device that I’m looking at is shipping to me.

< sigh >

Yet another disappointment… It’s too bad I just spent $24 on ten iPod dock connectors. I hope they come in handy for other things…

Any friends want custom car adapters? Like, iPod dock to tape deck or car charger or something?
