I finally got it working! I had to use the usb port so I'll need to get a touchstone for work, home and car but it is pretty sweet. It is pretty straight forward, but the hardest part was cutting the usb in half and soldering on it. I used http://www.qianqin.de/2011/09/18/samsung-galaxy-s-wireless-inductive-charging-mod/ as a reference. The wiring for the (+) is in the pics, but for the (-) I just slipped the black wire through one of the small holes in the bottom of the back cover and sandwiched it between the sim card and the metal sim holder to gain a ground.

I know it's not elegant, but I just wanted to share. As far as I know no one else has done this with a sensation.

Nice!
I think there was another person that tried but didn't get it working because he was using his stock cover and also said he couldn't get past some of the wiring. I forget but I think it had to do with the sd card being in the way or something.

But good job in getting it done!

Can something like this be done to keep from cutting the usb?

Unless you have a industrial grade precision solder station I doubt it. The internals are too small and crowded unlike the HTC EVO or Incredible. Believe me I tried; my phone has been completely broken down around 4 times already.

I was thinking of the same thing and I have the otterbox I was thinking of a way to attach the micro USB to the cover over the port.

That definitely would be easier than cutting into one, but the actual metal "plug" portion of the usb is too long. My pics are really blurry but I had to remove the pins, separate the inner plastic and outer metal, cut both in half and surgically bend the + pin into a square "J" shape, glue it in place, reinstall the metal casing and solder the pin to the wire without melting the plastic bit that holds the pin. It was a B!TCH!

Even though I cut the connector in half (actually closer to 2/5) it still sticks out just a bit unfortunately. There is a positive resistor inside the phone that could be used, but things are so tight that I doubt anyone short of a surgeon could solder to it.

I'm in the process of doing the same thing to my Sensation. I wanted to make sure that the Touchstone charger would support the weight of my phone in it's case, so I took the short cut of using parts from a microUSB charger to route from the induction coil terminals to the charge port. I'm halfway through routing all the necessary connections to go through the board instead of the charge port. In the attached picture, I've highlighted 2 test points that will let you route your +5v line into the board. I'll use the metal housing of the sim card reader to attach the ground.

Since the back of the phone is metal and its always going to be in a case I'm going to have to use pogo plugs or some other form of metal contacts to go through the back housing to allow me to pull off the case/back whenever I need. I'll have my charge port free to use over USB as well :D

The inductive charging mod lets you charge your device by simply putting it on a base.
