All you need is the metal foil.

The back goes on better without the metal disks and plastic cover, but you can still see the circuit bulge a little. Although I think the metal bits are still a good idea. The position of the coil has to be just right to pick up the field, the magnet helps it line up a lot easier. If you could position the transmitter coil in a cradle of some sort it would be fine I guess.

Just very minor soldering to circuit board using ultra thin copper wires and tape the circuit with ultra thin tape to a place where it's most room between back cover and the device itself. Even a mill thick magnets add bulk but the circuit is really flat.

True, there's a little gap above the sim card the IC's sort of fit into. The type of wire you need is called Kynar 30awg. It's well known for circuit modding, uses a solid core, is flexible, strong and great to work with. You could also remove the coil from the circuit and extend the wires. That way you could place the IC's somewhere else, but I couldn't really find anywhere suitable.

Edit: I'm going to use copperwire as in the picture in this tread and not going to solder to my phone. I'm also not going to use the magnets to prevent adding bulk. Instead I'm planning to make some kind of a holder wich I attatch to the touchstone dock to keep phone in right position. Just some plastic with an angle at the bottom and attatch it with hot glue.

The magnets are actually part of the base. There are steel disks in the back cover.

The pixi's charging area is so thin wonder if thats an option

The pixi did result in much less of a bulge. I would show photos but it turns out I am pretty terrible with a soldering iron! I somehow managed to de solder the contact pads on the coil so I have shelved this idea for the moment.
Anyone able to solder one for me if I sent a charging cover to them?

Anyone got a clue if it's possible to butcher the Nintendo DS wireless charger to do this? Because Home Bargains sells the battery and charging mat for £2.99 but not gonna waste even that if it's not possible.

You can still solder onto the metal area were the pads were. I just done this mod with the pixi guts and there is hardly any bulge on the back.

Did you read the voltage without the metal sheet just the coil?

can you post some pictures of the pixi coil? would be interesting to see the differences between that one and the one from the pre...!

wireless charging

everyone loves the wireless charging, it was a great idea to begin with.
the idea of just placing it on a mat and with no cables or plugs it charges,amazing...
cant wait for this!

You see some transient spikes, my DMM couldn't keep up. To all intents and purposes there is no voltage induced without the metal foil.
