The root password for each unit is related to the unit’s serial number. obtained the serial number by rebooting the Kindle while the Serial connection was still open. If the wires are hooked up correctly, then it just takes a press of the enter key to pull up the login prompt. Pulling up the command prompt was as simple as running Putty and connecting to the correct COM port. He then connected the Kindle to his PC using a small serial to USB adapter. soldered a small three pin header to the pads to make it easier to work on his device as needed.

This created a pocket that would allow him to route cables and adapters underneath this new mount.Īfter letting the epoxy putty cure for an hour, he removed the block from the pocket. also placed a flat, wooden paint stirrer underneath the putty. The washer would provide a place for an off-the-shelf iPhone holder to mount onto. He left a small opening in the middle with a thick washer mounted perpendicular to the ground.
