I was wondering if anyone tried to install one of these qi wireless charging receivers:

There are versions for both micro usb connection and directly to the battery connection points (but not for N900 - for galaxy types)
.
looking for 2 things:
1. to be certain that it'll work with the N900
2. to make it as invisible as possible (even use soldering if needed to the battery connectors)

I would like to install it since i have qi chargers at home for my android tablet and would like to use them for this.

any insights on this would be appreciated.
