Topic: Ipod/Iphone DIY line-in dock connector [photos]

[sunjan]

Just discovered this via the Rockbox forum:
http://ipodfoo.blogspot.com/2009/06/making-ipod-dock-for-recording-and-line.html

Most of us wouldn't bother, a line-in connector can be bought for $39.
But it's cool to see that it can be done at home. Great photos and instructions anyway!

This project adds a switchable line-out, which few of us need. That part can be skipped if you want to save time.

it may work for the ipod but it doesn't work for the iphone unfortunately.

Concluded from empirical testing, or because Apple says so?

I know all peripherals for the Iphone must have Apple's sign of approval, otherwise you'll get the warning message. But nevertheless, a lot of dock-connected devices still work, even if they haven't passed the approval process.

from testing, line out works but not line in

Thanks a lot for testing, it's always good to get field reports.

Just for the record:
 - which connector did you use (custom/DIY, or the Ridax one here: http://www.chargeconverter.com/shop/connector.htm)
 - which Iphone model did you use for testing
 - which recording app did you run (Audiofile FiRe or smth else)

If a transformer wired to take a balanced line and put it into an unbalanced line was placed in front of this, it could be VERY useful!

sorry but i don't see how balancing the signal would change the fact that it's not getting in the iphone . my next experiment will be to open a working line in device

this is very cool-
I'd like to try to make one and some how fit a line in  & line out - instead for the switch...
does anyone know where to get the iPod plug in the US- the links cited are all from overseas.
I think It would be cool to have my RockBox iPod  a record in & line out!

thanx

No US vendors, but qables and ridax both ship overseas, AFAIK.
Or you could pick up one of these, dremel a hole for line-in too:
