I have read some different posts and watched some videos on the internet about making a touchstone (inductive charging mod) from the inductive charging hardware from a palm pre. I tried doing this mod for my EVO 3d with no luck. I was trying the mod where you conect the inductive charging coil to a micro usb plug and plug it into the phone. I didnt' want to try the direct solder to the phone battery terminals for fear of damaging the phone. I think I have gottent the wiring correct, however I can't get the phone to charge. Has anyone had luck with this mod? any tips?
