I'm modding the S4 to work with the Palm touchstone wireless charging dock and found out that even without modding the phone the touchstone has pretty strong magnets that hold the phone all by itself. When I get some copper tape I'll finish the mod and show my results.

If you have the touchstone you can use it as a magnetic dock like I am currently. It's pretty cool, also it holds the phone pretty strongly, In fact I can use the phone while it's on the dock. Even when charging (usb cable connected) it still holds the phone nicely...

I'd like to see your mods to the coil. I was playing with a spare coil and trying to figure out how to position near the bottom and make the electrical connections.

Thanks.

Do all the Palm touchstones use qi technology or is that what you're modding. I have already ordered the module from wiqiqi for the S 4 for $25 bucks but didn't like the big flat plate they sold. This would be a great alternative for work.

No, the palm is not QI. You will not be able to mix and match coils and chargers.. The Palm coil and Touchstone only with work together.

i used .the left connector´s. It was more luck that it works because i don´t know why there are on the right side another connectors .
I couldn´t say which one is the positive and which is nagative because i didn´t test it. I´ve connect it like on my pictures and it work´s.
I´ve used the left connector´s because they are the same then on S3 and Note 2. I think the right connector´s are for NFC because the original Samsung Cover is "extreme" fat
With my solution there is a little camber in the Battery Case and nothing else. That means that you can use any nice thin Protection Cover for the S4 and it charges through the Cover.

Very cool. How effective is charging with this? How long does it take? Thanks.
