I never claimed the primacy

Thanks for the detailed description. Removing the PCB was a doddle, as was soldering the wire to the ground plane. The tricky part was doing the same for the charging pad. I eventually ended up cheating a bit, with a self-adhesive copper strip.

Here is the result:



It works fine, only a bit finicky. It is very sensitive to finding the right spot: just a few mm off and it stops charging.

But this is getting a bit OT, maybe I will find some time later to add more info in the wireless charging thread. This is just to say thanks Kimmo, you've been very helpful and instrumental in getting this done
