The original plan was to add a 5 volt regulator in the Dension cradle cable. I was planning to add it about 6 inches from the connector and heat shrink it when I was done like some sort of cable goiter. As I was checking out the back cavity of the cradle I realized that the regulator would damn near fit inside it. However, with the metal attachment bracket it wouldn’t quite fit. I ground down the metal bracket and sanded down the regulator a bit and everything fit perfectly. I added filter caps before and after the regulator to suppress noise and called it as day. The cradle is working well and is ready to install. As usual, pictures are below.

This resistor divider kludge marks the official start of modifying a pair of Dension Ice Link iPod cradles for use with 3G iPhones.  The Dension Ice Link is a cradle that fits a variety of Apple iPod models (and iPhones).  It plays audio out from the iPod through an OEM car stereo, and charges the iPod unless you have a 3rd gen nano, 2nd gen iTouch, or iPhone 3G.  These new models charge via USB only, and these old Ice Link systems only charge via FireWire.  With a little kludging, that problem is easily solved, and for $7 on ebay, these systems are a steal.
