The Voltage regulator chip was soldered to some short wires connecting to the usb female plug. THe entire mess of wires, usb port was mounted (black electrician's tape) into the altoids type tin. A small opening was cut into the side of the tin to allow access to the usb port.
See the following pictures.....

The not so messy inside with black electrician's tape.
For the final mounting, the usb port was taped to a piece of styrene (plastic modelling material, the white stuff you see in the tin) which was cut to size to fit the tin, This was to give it some rigidity and stability when plugging and unplugging the usb cables. The voltage regulator and wires were also taped on top of the styrene and the entire thing taped into the tin.


Now with a sync and charge cable for my treo, I'm all set for emergency power....
