Hey there,

at first the usual warnings:

If you do something similar as described in this thread you
- loose the warranty for your device,
- may damage or destroy your device,
- may cause damage to you or your environment,
- might do other dangerous stuff!
If you try to do anything of this you do this on your own responsibility and at your own risk!
There is absolutely no warranty that this will work for you.
Furthermore, there is no warranty that the posted information is correct at all.
Do not blame me if you mess up your device or something else by trying to do this.


That being said, lets go to the fun part:

I made some rather brutal modification to my N900 which allows me to charge it with the Powermat (TM) system.
So far it basically works.
One issue is that the Powermat sender stops charging after some 20 minutes of charging.
I didn't actually measure the time yet.
Though, this works as a very first proof of concept.

I attached some first pictures taken of the device being charged and the modification itself.
I'll add more pictures of the nasty work and inside of the device and also more details of how I did this later on.
