Xperia RAY induction charging mod - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

Just finished the Sony Ericsson Xperia RAY induction wireless charging mod
http://www.pbase.com/xperia_mods/xperia_ray_induction_charging_mod
All you need is about 15$ to order "Palm Touchstone" kit on e-bay, a bit of adhesive copper foil and
2 ohm SMD (1/8 or 1/4w) resistor is needed to balance on peak. Will not work without it.

Great mod indeed. thanks

yes. I't like to pay 39.99 for this magic battery and skip doing this tedious reverse engendering.
But this Powermat was still not out in the market of more then few phone models. In this 2010 video they'd planed to integrate induction coil into the battery. The idea with the battery replacement was great but still not commercially available. I suspect in reality it was tricky to make it work and it will reduce the battery capacity (as some battery room will be taken by induction coil and charging control circuit). Also Li-Ion battery can blow up or ignite when overheated or shortened. I guess they don't want to take this extra responsibility. So they roll back to selling Battery Doors & special bulky cases with induction coils. The need to integrate it into the heart of the phone (as we do with soldering + wire to the usb plug) prevents them to apply it to more phone models.
But your question can lead to a new great mod.
We can use this "Battery Door for BlackBerry Curve 8300" for just $4.78 or this and integrate it into the Xperia. However solution will be more expensive (due to mat costs) to that with PALM, we might skip ripping the phone, soldering and voiding the warranty.
If somebody will donate me this receiver door and the mat i'd try to do for him...

so you think we can have a wireless adapter for our mini pro?

I need to see it. I used to have x10 mini and the back of it was not flat. So it can prevent proper contact of coils. mini pro is a bit flatter. i need to hold it and Palm or Powermat coils in my hands to confirm

---

i had x10mini also.
unfurtenully i cannot donate you the material but i want so much wireless charging.
in alternative i have an idea:
maybe its possible to attach something to the battery to use duracell inductive charging mat no?

all this inductive charging works on the same principal
you need coil + mini controller + tiny align magnets on both sides.
unfortunately you can't connect it directly to the battery as li-on/li-pol battery are not that easy to charge and phone should control the charging process.
So you need to connect it to usb charging.
Maybe you can use something like this that connects to micro usb plug:

(•͡˘˛˘ •͡)" hmm ◦°◦ºº‎ ◦°◦ºº...

Did somebody else perform this?

I would like to try this on SK17 but I was thinking of using the non soldering method.

Just need to find out if there is any point with VCC and GND that might be used.
I will order the touchdown and try this when I have the time

Question on the resistor
Hey There, im currently based in HK and im struggling to track down where i can get a 2ohm SMD resistor (is it 2 omh or 2k ohm??), Could you link me to a site i could buy them from i have tried Google but no luck on just getting a few. Would very much appreciate it.
Cheers,
Paddy

nice i try it too.

---

would love to see this on mini pro

Great stuff! Will be trying this.
