The mod involved buying a Palm Pre Wireless Charging Kit. Both the charging puck and replacement backplate were needed. The coil and magnets from the Palm backplate were transplanted to the Nexus One backplate, and the coil was wired into the dock connectors on the bottom of the Nexus One. The dock pins provided an extremely easy way to connect the coil to the Nexus One. Note that the wire used is very fine motor winding wire. Also note that the Nexus One backplate was sanded down to make room for the coil and magnets. This provided better adherence to the puck and probably provides better charging performance. Charging performance is still being evaluated. The voltage measured off the dock pins when charging was 5V. The charging process was very slow with the screen left on, however in sleep mode the Nexus One charged completely overnight. A welcome discovery of this project was ease of installation. The Palm Pre was originally thought to send some sort of proximity signal to the puck, but this turned out false. The coil will provide 5VDC when in proximity to the puck, nothing else is required. This makes it possible to accomplish this mod not only with the Nexus One, but with a wide variety of 5 volt (any USB) devices.
