The 17-foot iPod Dock Extension

It's been a few weeks since I first posted about the iPod Dock Extender Cable I hacked together. Since then I've sold a few of these through CableJive, which gives me a good excuse to play with the soldering iron and som every tiny soldering points in the evening after the kids are asleep.

I recently got an email from a fellow in Sweden who was looking to put an extension in his car and wondered if there was any chance an extension cable would work properly if it were 17 feet long.

Seemed like an interesting enough experiment. I figured at some point it would be good to know the upper limits of this hack. So I cut a length of cable, attached the necessary adapters, and plugged it in to see if the iPod worked 17 feet away from my SoundDock.

The answer is yes, it works.

Now you must note that the dock extender cable featured in my hack only connects power, control, and sound from the iPod. If you were attempting to do video across 17 feet of 28 AWG wire the picture would probably not be so great. But the sound is good, and power and iPod control come through just fine. I broke out the multi-tester for some hard proof just to be sure the voltages were still correct on the far end of the cable.

With that good news I shipped the cable off. Somewhere in Sweden there's a car with an iPod in the front seat and an iPod dock and stereo in the trunk.

Magically connected.
