How to Charge Galaxy Note II With Simple Wireless Charging mode
Simple wireless charging - Ten Minutes & Under Ten Pounds
I've decided to go ahead and do the mod for the wireless charging as i've seen a few threads tempting me.
What you need is:
Palm Touchstone £5.24 (Amazon UK)
Palm Pre Touchstone case £3.49 (eBay)
Heat Shrink
Electrical Tape
Speaker Wire or any other thin multi-core wire EDIT: Copper foil tape, would be better (thanks rj3005)
Solder Iron & Solder
This all cost me under £10 excluding the solder iron.
1) I first took the induction coil out of the Palm Pre case carefully.
!!! Its very important that you peel the silver sticker off carefully and not cause any sharp bends which could cause cracking. You need this silver sticker to stay intact for the whole operation to work. !!!
The top pin is positive and bottom is negative as shown in the picture, this is also the same on the note the top pin being positive and bottom negative.
2) I placed the coil in the center of the Note battery case I then placed the silver sticker over the coil as it was on the Palm Pre (this is very important that you place the silver sticker back over the coil as without it the induction doesn't seem to work.)
3) I then checked where the charging pins on the note meets with the case and marked it with a pen to indicate where the wires would have to be.
4) I cut two speaker cables to length and strip the insulation off leaving the wire itself, I then place heat shrink over them and heated them up. (This is up to you as it depends on the outer sheath thickness, you want it thin to prevent bodging in the case.)
5) I then soldered the wires to the charging circuit positive and negative and lined it up in the case with electrical tape. Once I was happy I placed the original insulation cover over the coil with the magnets.
6) I placed the cover over the Palm Touchstone dock and checked the voltage from the wires with a meter (should be 5.6V any less means you have left the silver foil off or not placed it correctly) to check everything is working and the polarity is correct.
7) I placed it back on my phone and there you go, I now have wireless charging.
NFC works and magnets do not affect the phone testing the S Pen and Compass seem to operate all good.
Sorry if its a bit brief, I will try and write it up a bit better.
EDIT: Measurements I've taken
Output Voltage 4.8V (5.6V disconnected)
Output Amps 0.42A
