I’m wondering. Couldn’t you just run the contacts from coil to the positive and negative pins on the device where the battery makes contact?

need pics the ones in the other page are broken links. dude how hard is it to just borrow a friends phone to record and take some pics.

Ordered the Pre cover and Touchstone. Hopefully they get here soon. Gonna try and make it as clean as possible with no wires from the phone to the cover. Try and keep it more like the High WAF Wireless Inductive Charging Mod.

Will post instructions and PICS

inductive coil with PIX WHOO HOO!!!!!!

---

The first thing i did was i went to radio shack and i found a palm pre back on clearence for $.97 SCORE!!! following a website where they did a "non solder" mod and it doesnt void the warrenty ^_^ so i took the sticker off the back of the door showing the inductive coil if i was intellegent enough i would of taken the sticker with the metal discs and placed them on my battery door but unfortunally i was not that smart. so heres the coil all by its lonesome. Moving on, ok now i have taken apart my phone (you can find all the screw holes and they are all out in the open where my screw driver tip is are little notches are the best areas for prying off the back (that way you wont damage the chrome border) Now also make sure that you have purchased some copper foil. around here in the midwest i found it at my local hobby lobby in the section dealing with stained glass for around 7 bucks (that coil holding up the scissors and the back panel of my phone. So now that i have everything exposed we need to only worry about the place where the battery meets the main board . Unfortunately i didn't take a pic here but if you look at the battery you will see that the other leads are the main terminals for the battery, biased upon the picture the negative is on the left while the positive is on the right. My screw driver as seen here is the negitive terminal. So what i did was i place some of the copper foil over the negitive side of the termiman (sticky side down so that it stays in place and folded over the terminal)and i did the same thing for the positive.After i did that i placed the back, back on and but be careful because placing it back on is not nearly as easy as getting it off. This here is the top of the back of the device. Make sure that you place these (as shown by the tip of my screw driver) in first and the rest will just snap on. Now here ] i folded the sticky sides together so that they wont stick to anything and they cover my battery. That way when i place my back with the coil taped into place they will make contact. Now moving to the backcover.......i aligned the coils terminals with the battery terminals and grabbed some good ol'fashioned electrical tape and taped that bad boy on to the battery cover then i ran the copper tape (sticky side facing the cover) and created "trace patterns for the contacts with more electrical tape to secure everything and i placed it all together turned it on and made sure that it worked.... HURRAYYYY!!!!!!! ahem....anyways i was able to snap everything back together and it's not much thicker then before but ya can feel the coil. Now for an added touch today i was looking around @play.google.com and found and NFC app called "NFC RE-TAG" http://goo.gl/Q4GKL which allows you to re tag any nfc so i opted for the free version. My kids have a videogame called Skylanders for the wii (don't flame me), and pc. For those of you whom don't know what that is, it's a game that used NFC figurines that have special powers and you place them on a NFC reader called a "power portal". I was able to read the tags with the induction coil in place so there yall go the induction coil does not interfere with the NFC coil

its not that, being that i am a stay at home father i just simply hadnt had the time with 4 little ones running around and working full time, time is in short supply

take a look at what i had done, it does not require you to solder anything, and unless you are really good at soldering i wouldn't suggest it. The method that i had stumbled upon does not require you to void yer warrantee nor does it break any seals so if something happens later on and you have to get it replaced then you don't have to worry ya know????

Curious about leaving it on the charger overnight. Wondering if there's a way for the phone to know its full and stop or if it'll continue to charge. Thinking it might be a problem as its not passing through any resistors.

If it works this is much easier than soldering.

I was kind of thinking this. Putting it directly to the battery worries me some. I feel like it would over charge it. Correct me if i am wrong ofc. But it would be nice if there was more input on this.

i am only "slightly" worried and this stems back from when i had a (please dont laugh..) htc wizard and the usb port no longer worked...and since my soldering skills where not up to par at that point in time what i had done was to take twist tie and stripped them down to make wires. In my infinate (sp) wisdom i looped the wires around the battery contacts of main board and then clipped the wires of a spare charger (like i said not my finest moment....). After figureing out which is the proper terminals for charging i put the battery into the unit and then wired it to the charger... Low and behold it worked (until the battery terminals snapped....) But until then the unit didnt over heat and/or short out. now i am not advising this but i didnt noitce any harm...(wasn't until later i figured out that i could of gotten an external battery charger, but thats another story...)

Thanks for a nice tutorial Rastlin!
I have a question...
Where can I get the charging surface for it?
And how much it costs?
Tomorrow I will go to buy all the things, if I can find them.

Wish me luck!

ITS WORKING...

It took some courage but finally did it. It's not as hard as everyone thinks. USB port still works. NFC still works. I don't notice any difference in charging from the touchstone and usb. The back does bulge out just a bit. I can feel the difference when the phone is laying flat on it's back.

This is assuming you have all the necessary parts.

Copper Foil
Solder / Solder iron
30 gauge wire
Pre back cover (for coil)
Touchstone charger


Check my post earlier to see a video of how it was done on the original galaxy. It's very helpful.

1. Remove the battery door

2. Unscrew the 6 screws



3. Once removed, using an old credit card, work your way around to remove the back cover to expose the board. Take your time.

4. Using your finger nail, disconnect the highlighted points

5. Slowly remove the board off from the housing

6. Once removed, turn it over to expose your soldering point. I chose to use the resistor. The USB pins are to f-n tiny to solder. Just make sure to solder it to the side of the resistor and not the top. BE CAREFUL NOT TO FRY IT. (my soldering sucks which is the reason i decided to go with the resistor)

7. HERE'S WHAT NOT TO DO. DON'T SOLDER IT TO THE TOP.

8. Instead, solder it to the side

9. Once soldered, run the wire along the right side

10. Connect the 4 connectors removed from step 4

11. Cut the wire to length

12. I don't have a pic of it, but solder a piece of copper foil to the end of the wire.

13. Position the back cover and tape the foil like so

14. Snap the back cover in place and screw

15. Using the coil from a pre cover, position everything in place. Cut 2 L shapes using foil and position as so. The shorter one is for the positive and the longer one is to ground. The top contact point on the coil is positive and the bottom is for the ground. Cut enough to wrap the foil around.

16. Solder the foils to the contact points

17. Position the coil on the back with the battery door off. Put the batter door back on so the coil will adhere to it
