Hi guys,
I bought myself a QI charging board for my Nexus 4 a few days ago, and decided to build a dock out of the Depron I normally use for RC planes. Now I want to share my build-process to you, as well as the blueprints I created and used.
If you want to build one, too, you need the following parts/tools:
1x A4 sheet of 3mm Depron
1x A4 sheet of 6mm Depron (or another 3mm if you don't get 6mm)
a SHARP cutter knife
UHU® Por Styropor-glue or similar glue
my attached blueprint as PDF and dxf for LibreCAD
and of course, a QI board, e.g. Amazon.de | Amazon.com

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
After you printed the pages of attached PDF to an A4 paper, you can softly glue the first page onto the Depron sheet with some sort of spray glue, I used 3M SprayMount for it.
Wait with the second page, for now.
Then cut out the parts with the knife, be careful not to hurt yourself! The knife should be very sharp that the Depron gets cut cleanly, and doesn't rip.
Don't cut out the parts marked red in the blueprint, they should only be slit slightly. After you finished one part, you can safely remove the paper from it, use the knife to pull it away. Put away all parts except the ones with the red mark. Use the knife to remove a layer of about 1mm inside the red circles, look at the picture for a template.
You do the same at the position where we later store the cable, look again at the picture for a template.
Remove the coil from the board with a soldering iron, as the cable is too short currently. Solder the coil onto piece of cable then, don't connect the cable to the board by now!
Glueing time!
Begin with the parts which hold the QI coil: first put the coil into the backplate, then glue the front plate on it. My glue required me to put glue on both sides, wait 10 mins, and then stick them together.
While the backplate dries, glue the two triangles to the long rectangular, this will later keep the phone from sliding to the front/hold the phone at the charging plate.
After everything has dried, glue the front part to the backplate.
Glue the triangle to the backplate like this:
Now take one of the bottom plates, and cut a hole for the cable. I marked the position with a pencil, I suggest you doing the same. Glue the bottom plate to the other parts.
Now it's time for the second page of my PDF:
This page should either be glued to an 6mm Depron sheet, you then only need to cut out one of the parts, or you glue it to a sheet of 3mm Depron, and cut out both parts, which then will be glued together.
Glue the just created part on the remaining bottom plate from the first sheet, and lay the circuit board into it.
Cut the cable from the coil to a suitable length and solder it to the board. Be very careful while soldering, Depron melts easily, also make sure the cables don't get to hot! Then, you can glue the bottom case and the plate together, and you're basically finished!
In the end you can apply some finishing touches, like smoothening the borders/edges where you glued pieces together. You can of course also paint the dock in any color you like, I will maybe paint mine with a black acrylic dye later..
Result:
I hope you liked my little How-To, if you have any suggestions or ideas, feel free to comment.

I am gonna try this.
Thanks
first of all, very nice charger. nice work and thank you for sharing.
now i have two questions.
1) how much time does it take to charge and how much ampers does that charger output?
2)does the charger circuit overheat in the base?
thank you in advance

Well, I charged the device from 20% to 100% this morning, and it took about 2½ hours (probably less) to charge, I didn't look on the clock though.. Ampere says about 600mA with a 2A ZTE charger connected to the board, I cannot use the Nexus 4 charger (Got an US version).
Overheating was my biggest fear, but it actually stays absolutely cool. When well positioned (like on the dock) it stays cool, far away from melting the Depron, while when I in before just laid the phone onto the coil outside the dock, it got pretty hot.
Ah, and next time, please don't quote the whole OP. Maybe even edit your post now.

No problem. Glad that you like it
Quick status update: I found out that the triangle stabilizing the charging pad isn't that robust, so I suggest either using a 6mm Depron for it or even two 6mm Depron triangles at the left and the right edge..

I modified an iPhone cradleto a Htc Desire cradle, later today i will post the instructions about how to modify this about 5 dollar cradle.
it fits perfectly because the iPhone has almost the same witdh and tickness .
i'm not responsible when you screw up the cradle or phone, i'm just sharing my creation.
This are the items, you need:
The Iphone dock: $4.51
http://www.dealextreme.com/details.dx/sku.31705
The dock cable: $1.80
http://www.dealextreme.com/details.dx/sku.40078
The dock for using the female connector: $3.14
http://www.dealextreme.com/details.dx/sku.21892
Micro usb plug And Mini usb: $2.24
http://www.dealextreme.com/details.dx/sku.36150
Preparation:
Start bij disessemble the " Micro usb plug And Mini usb" and "The dock for using the female connector" cable
The easiest way to do this is by using a knife to, the 1 cable is a bit difficult because it's glues together, make shure you het the mico usb like this and the mini usb like this.
Tip: try to keep the red and black wire from the female mini usb connected, this prevents solding work later on.
Also when you extract the female ipod connector keep the wires attached so you can soldeer it lateron to the micro usb (male), when you done it right, it will look like the picture below, with the wires connected.
(Don't mention the desiciptions of the pins on the picture below.)

Opening op the cradle:
On the first sight you won't find any screw-hols on the bottom, but they are the on the left and right side of the cradle bottom the are weak spots in the rubber, make 2 holes and you will see 2 screws, und-screw them an open up the cradle.
when the cradle is opened you'll see a print, you can remove it, it's not nessery anymore, in my first attemt i tried to use the audio port also but then i figuered out that the HTC Desire has no audio over usb option.
Assembling the HTC DESIRE dock
Starting with the most tricky part, solding the wire from the ipod femal connector to the micro usb male like the thumb below.
(Make sure the wires al long enough)
when this is done make a hole in the housing on the left side of the ipod connector. This is for the mini usb (female). Solder the black and red wire of the mini usb to the pins on the ipod female connector.
Now the difficult part is done.
Take some black tape an cover the innerside of the hole where the ipod male connector was. In the middle make is small insision where lateron the micro usb male connector had to fit through.
Take the bottom plate of the cradle and carefully take away some plastic like the photo below
Now this is done, the easy part begin. It's glueing time
Take your beautiful solding work and fit it in the cradle starting by fitting the ipod femal in the ipod female hole, and the mini usb female in the mini usb hole.
Stick the micro usb male intro the insision you made and attach your phone to it. To make use everything fit, assemble the bottom to the cradle.
When this is fits, heat up your glue gun or plastic glue and qlue everything in place, be carefull that you dont glue your phone to the cradle
Wait for a day so the glue is hard and than attach the bottom to the cradle.
and "whala" a beautiful Desire Cradle
pictures below are to help you get an idea.
cool thanks

Exactly.
Sent from my HTC Desire using XDA App
what fuctions does a dock exactly serve? apart from looking pretty?
Does the phone automatically switch to the desktop clock mode once plugged in? or similar?
As you said it looks nice on your work desk or at night as a clock.
But it also provide a nice and efficient way to refill your battery.
However i don't think that you it auto switches to desktop clock, you have to set in on your own. Some said that it's cradle specific, but i'd rather think that the Desire doesn't allow it, contrary to the N1
Just got mine this morning, it shipped pretty fast from HK.
Usually it takes around 3 weeks, and this time not even one
For 14euros i got a really nice usb cradle with the room to put another battery, a free screen protector (really efficient and easy to put on) and an extra power adapter with the plugs according to your country (EU/US/UK...).
http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=110542237110&ssPageName=ADME:L:OU:FR:1123
Can't take pictures right now, but it's definitely worth buying from him since he's a serious ebayer.
Looks nice, do you have a case on your phone? Just wondering if mine will fit on it with a case.
Not yet, they shipped from HK since 2 weeks and yet not arrived, while i bought this one on July 29th and it arrived today (Aug. 3rd),
There's really little room on the sides so I think that a "barely there" case (original or copy version) would fit.
Here's the copy i've ordered that might fit: http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=250663722867&ssPageName=STRK:MEWAX:IT
On the contrary, this one might be a little bit bigger in order to fit : http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=250663666312&ssPageName=STRK:MEWAX:IT
Glasses alright? ;-)
Dude, promise me that you put on your glasses next time when you publish photos online
A little bit off topic, but does anyone know a cradle that would fit a Desire with invisibleshield applied?

I sanded down the the back cover so the inductive coil and magnets would fit and drilled a hole for the wires because if they come out at one of the antenna holes the back cover doesnt come on all the way.
Just use the ground and 5v lines from the USB port. The touchstone back outputs 5v. I did this on my evo, and am looking to do it on my epic now also. google for a mcro USB pinout and figure out which pins are what. I know that the far left and right pins are negative and 5v, but i dont remember which is which.
please to be explaining what is going on here
the touchstone is a palm device paired with a palmpre to wirelessly charge your phone. it uses a series of coils and magnets to hold the phone on to a charging base that plugs in to the wall. this mod basically allows you to do the same with any other phone give you have the base and matching battery cover from a palm pre. you just remove the induction plate from the back cover of your phone and attach it to the new phone as best you can. the best mod ive seen is to a touch pro 2.

okay so its not really wireless u still have to keep it stuck on this pad...right???..ahem...so wuts the difference whether u plug in a usb or place it on this pad ur still attached to the wall...sorry i dont get it

It would be safer to plug your phone in and use a multi-meter to find +5 and ground. It looks like the USB port has 8 or 9 pins coming out of it, and standard USB only has 4.
After that, simply find the +5 and ground on the touchstone coil and run a couple of wires to the USB pins
Edit: It looks like the second pin from the left is the +5, but It's hard to tell just looking at the picture. I'm making this guess based on following the trace that it's connected to.
I have a touchstone as well, so I will definitely be watching this thread
This is all too complicated for the end user, maybe somebody should just reproduce this in like a battery pack. I would be willing to pay 20 or more for a mod like this. Just saying...

The technology behind it is dead simple though. It would be trivial to introduce something like this built into a battery pack. IIRC, the voltage on the receiving coil is Vr = Vs * (Cs / Cr), where Vr is the voltage on the receiving coil, Vs is the voltage on the sending coil (the touchstone base) and Cs and Cr are the number of loops in the source and receiving coils.
Therefore it would be easy to make a coil that grabbed 3.6V from the 5V touchstone and fed it directly into the battery. The only problem is that the coil plus voltage protection circuitry inside of the battery would reduce the amount of space that you could actually use for the battery. Considering how small batteries in cell phones already are, even making them a sliver thinner to fit the coil inside of the battery pack would mean a drastic drop in battery capacity.
To the OP: did you have to break any stickers to pull the circuit board out?

The compass should work fine. The metal disks on the palm back cover are not magnetic. I believe they're just iron disks...

Still the strong magnetic pull from the touchstone base to keep it attached will make the compass act wonky.
I had a leather case for my hero that used a magnet to close the flap and i would have to mess with the compass for like 15 minutes to ever get it to point right again.

Hey guys. I ordered an orb and it should be here in the next few days. I am thinking about taking it apart and mounting the orb inside my bed side table. It's just made out of pine. I'm planning to router the under side of the table down to be only 1/8 - 1/16" thick so that there is very little for the charger to have to work through. I figure since wood is very porous and non conductive it should be able to do it. Has anyone tried this yet?
EDIT:
So I re-routered the wood down to just 0.020" thickness (approx 1/64") and it works! Here is a video of it in action:
whelp, im going to be the guinea pig on this one. here are my progress pics.
The end table (that I made 15 years ago in high school):

An area that I think will work well, approx 3x3" under the top of the table:
And after plunge routering the area out.
I left the wood thickness at about 0.080" which is roughly 3/32". As soon as the orb arrives this week I will see if it will charge through it, and if the gets hot, and if the rate of charge is affected by the wood.
AW: Inductive charging through thin wood?
This
Is
Awesome!
Im pretty sure it will work perfectly

Re: Integrating orb charger into night stand.
It should probably work, but you could have bought a cheaper charger. The orb is quite expensive and there are much cheaper Qi chargers available

All the cheap ones seemed kinda sketchy, and the decent ones are either not available (in Canada) or cost the same/more anyways.
Edit:assuming it works well I'll probably pick up another charger to use in this project once the decent ones come down in price then I'll bring the orb to work.
Re: Integrating orb charger into night stand.
If this works, you are a genius. Well, you get credit either way for even thinking to try it. Please update and let us know if it works. What's better than setting your phone on the night stand and having it charge? Every one of my drops so far has occurred when the cord gets pulled and brings the phone off the nightstand with it.
cool DIY!
though it may be a waste to dismantle the Orb for this.
There is already some model designed for table charging. But if it charges through the wood surface, the idea of hidden charging pad is definately much cooler!
woot! my orb is shipped, left KY last night, in OH this morning. Scheduled to arrive Thursday!
This is a cool project, but if I were to do it, what I would try is dismantling a charger (orb works, I would use the LG charging pad), making room for it in the desk and just have it be exposed, making sure everything is level, then cover the entire top in 3M vinyl with a wood pattern. It is going to be REALLY difficult to make actual wood be thin enough, but I look forward to seeing how you manage it!

Ive looked high and low and can not find the LG WCP700 charging pad / ANY quality qi charger for less than the orb.
I think im going to keep the orb intact but maybe just remove the rubber part. I figure the thickness of the wood is less than that rubber piece and/or a TPU case so it should have little to no effect on it. Ill be using the official nexus bumper with just a rear screen protector to cut down on the amount of stuff that the charge has to pass through. Like I said though, I have already routered the wood is down to only 0.080" thickness which is already thinner than a standard TPU case that people are successfully charging through.
Its kinda funny - you can tell where the spot is from the top because it feels like the face of a drum. Once the charger is mounted under their though it should firm it up a bit... at least I hope. Kinda afraid to puncture through it. LOL.
also, my orb is now in Toledo OH... just 130mi away... would be sweet if it shows up early
I posted a similar question recently and didn't get much response.
To me, I want a landscape charging stand with NFC. The NFC is easy with a sticker-tag, and I currently have this cheap plastic stand that I put an NFC sticker on. The challenge is that I still have to plug my phone in, and the cord makes the landscape a bit wonky.
I was wondering if anyone had dismantled a wireless charger and inserted the pad/coils/whatever into the back of a landscape stand. Wood is obviously the easiest, but if someone has a 3D printer, you could get really fancy with it.
Interested to hear how you get by with your project, too, though.
Well the orb came in and I'm sad to report that it barely charges through 3/32" thickness of pine wood. You have to very exactly place it dead center for it to recognize it, and it charges really slow. I'm not done with this idea but it is back to the drawing board.
WORKS! Check out original post.

Saw the vid! Looks awesome! But I would need a NFC sticker or a X to mark the spot. And it would never work for me because I have stuff all over my nightstand lol.
I only also have a tv remote. I'm going to put some kind of mark to help locate it, but it works great otherwise. I also have the current widget and there is not a decrease in charging current either.

http://www.aliexpress.com/item/Qi-s...ile-phone-general-radio-charge/758486168.html
I will start off by saying I had a picture. I know I took it with an old phone but when I started it up again a little bit ago it was not there. Don't know how I managed that. I have to open it again in a few days when my new power button shows up so I will take photos then and add them. For now you get the crappy paint diagram.
I Performed this on an AT&T HOX released back in May Model PJ83100.
This fix gained me FULL or near full WiFi signal in places I was getting ZERO signal before. I could not get WiFi at the back of my house on the inside, now I get connected in my back yard. I really thought this was going to be a waste of time but boy was I surprised at the signal strength after.
I TAKE NO RESPONSIBILITY IF YOU BREAK YOUR PHONE DOING THIS OR IF SOMETHING HAPPENS IN THE FUTURE. YOU ARE TAKING THE SAME RISK I AM IN TRYING THIS!
Basically I popped the phone open with a thin guitar pick run along both sides from bottom to top pretty much like every video shows. (DO NOT USE A HOOKED OBJECT, you will be sorry!!!)
On the inside of the back of the case on the left edge just below the usb port hole are two gold contacts. They are the pair closest to the edge of the left side. I saw the letters BT with some numbers before/after them printed on it.
Starting with the lower of the two contact points (farthest from USB hole):
I got out some tinfoil and used an exacto knife to cut a 2 - 3mm wide strip. At one end I made it the same width as the gold contact but twice as long and then folded it over on to itself over that wide section to make it twice as thick at the contact point and the same size as the contact. I took a 3 inch strip of some scotch tape and attached it to some clear plastic. In my case the address "window" on a piece of junk mail. I then used the exacto to cut the strip of tape in to thin strips about 6mm wide. I took the foil piece and laid the wide end over the contact point and let the thin 2-3mm "tail" run along the black cover over the real antenna towards the bottom of the phone. Basically from the contact point straight towards the bottom. I had to dry fit it and trim the thin part (the tail I mentioned earlier) to length so its just as long as the black material under it that covers the actual antenna. I then used a small strip of the tape I trimmed to completely cover thin part of the strip except for the wide part at on top at the contact point.
The Second contact Point (closest to the USB hole):
On this one I did something similar but instead of it being straight it was more ad upside-down "L" shape. The hook in the bottom of the L was the part I put over the contact point and again made it double thick and the same size as the contact point but a bit longer. I then cut the longer "leg" of the L at 2-3mm thickness same as the first piece of foil. There is a space between the BT/WiFi antenna's black insulating cover and a big black square covering nearer the middle of the phone that matches up with it being behind the battery and the NFC antenna just above that. It is the actual polycarbonate of the phone. In other words there are no antenna or anything else there its a white spot on my white phone. I laid the 2-3mm leg in that area directly against the back of the phone and used another thin strip of tape that I had cut similarly to above to cover it. This piece of tape I let run a little longer above and below but not over the part of foil on top of the contact point.
Finally I took a full width piece of tape and went across both foil legs up to the contact point of the first, smaller piece of foil. Again making sure to keep the contact point uncovered. Over the rest of the L shaped piece I used a smaller thin strip of tape above the wider piece to cover the rest of that one a second time.
Bottom line you DO NOT want either piece of foil touching the other and you DO NOT want any of the foil except the area on top of the contact points exposed where some part of the electronics of the phone could touch it and fry your phone. I used scotch tape if you want to, use electrical tape. I wanted something that would come off easily leaving behind little to no residue or doing damage coming off.
If you have done this correctly you should have something that looks like this:

Adding:
I have seen others talk about using foil or solder to fix this. I am not reposting someone else's idea. I haven't seen anyone do anything with foil other than cover the contact point area to make it thicker and reach the gold prongs on the board.
I'm also adding that there was no real science or theory behind this other than the foil would increase the antenna surface area and the double thick part at the contact point would make a better connection with the phone electronics.
Might try this if I replace the battery with the X+ one.

Not sure what the inside of the X+ looks like.
I have seen many disassemble videos and only one actually looked like my phone on the inside.
I should add that my Bluetooth worked but was awfully short range when compared to an other phone I have owned. With this change Bluetooth was connecting and staying connected much farther away. Can't say if the quality was good when connected, just noted it was connecting where it wouldn't.
Photo added now. If you note the foil on the upper contact point shifted. I repositioned it closer to the area the prong contacts the back before re-installing. Didn't hurt or help wifi reception anymore than it already has.
I will also add that the power button ribbon cable with attached upper mic replacement was a bit harry. In the videos you can see online it is obvious that the people shooting them don't give a crap about the prongs on the board or putting it back together. They just blow through ripping it apart. When you are worried about it actually working when done you are much more cautious/nervous!
Also, tip for anyone who cares. The screens power comes from two contacts at the top of the board that touch prongs on the top, back of the screen. If you try to turn it on (like I did for testing) and don't get a picture and you didn't screw it down that is why!
Wireless/Inductive Charging With Case for hTC One XL/Evita
Here is a simple mod I did to wirelessly charge my One XL/Evita
This doesn't require opening your phone, will therefore not void your warranty.
It can be used basically with any snap on case.
NFC works fine with mod
YOU DO THIS AT YOUR OWN RISK
I AM NOT RESPONSIBLE FOR ANY DAMAGE IF YOU
DECIDE WILLINGLY TO APPLY THIS MOD TO YOUR PHONE.
Requirements:
1. pencil, paper, tape & ruler
2. soldering iron preferably with a fine tip
3. copper foil adhesive tape, width ≤ 5 mm
4. restover thin cable (width ≤ 1 mm), will use this to make prongs/pins
5. thin transparent plastic sheet (from any old packaging material), to make extension platform
6. thin wireless charging receiver card (qi standard)
7. an avometer is handy if you have one
8. thin double sided tape keeps things tidy
9. Dremel tool if you have one, to grind pins
10. basic drawing and soldering skills

You will of course need a wireless charging pad.
I went for "qi standard" due to availability and reasonable pricing.
Method:
1. draw your phone on paper with receiver card superimposed, lines where 2 copper foil paths will run between contact points on card and the 2 outer pogo connectors.
Note: upper pogo connector is positive and bottom is ground.
Tip: you can lightly tape paper to phone and rub pencil where pogo connector is to give you an imprint of all connector points
2. cut transparent plastic sheet big enough to cover positions of card and pogo connectors on paper. Tape it lightly to paper and draw the lines on plastic with fine permanent pen.
Notice polarity of both card and pogo connector as in pic
3. you need to remove prongs from charging receiver card by carefully and shortly applying hot soldering iron and either push with solder tip or grab with tweezers.
After this you can lightly tape card to plastic sheet within it's drawing, blue side facing paper and white facing up.
4. cut the copper foil tape into 2 equal strips, each was about 2.5 mm in my case.
5. making pins/prongs was the most challenging part. Strip about 1 cm of thin cable and spread some solder on it just enough to make it solid, then cut in half. You can check at this point if they fit comfortably in your phone's pogo holes, may need a bit of grinding.
6. now carefully solder those 2 pieces of solid wire to ends of copper foil strips while taped on paper, it's better to shorten them after soldering, I had to use my Dremel to grind/dull the edges a bit.
7. tape copper foil strips to plastic sheet along drawn lines, use imagination and fine tweezers to bend foil strip at 2 corners, solder strips to 2 points on card. Plastic sheet can be trimmed to suitable size at this point.
8. if you have an avometer you can check if your connections are intact
9. now place the whole thing on phone aligning pins to appropriate outer pogo holes, small piece of tape should be adequate to keep it in place, snap on your case and slide your phone onto the charging pad!
I need to grind my pins a tad shorter!

How to mute Koolpad wireless charger
Some useful pointers for those interested:
- wireless charging receiver card (for S3) I used didn't interfere with NFC functionality
- this mod works fine with my other HOXL cases, the one above is the thickest though, melkco Premium Leather snap cover
- charging time, averages 10-13% in 1 hour, adequate for overnight charging or desktop topping up
- battery/card gets a bit warm but not hot
Koolpad qi wireless charger
As pictured above is not cheapest around, but it had good reviews.
charging distance 8mm
current 500mA-700mA
doesn't overheat
not very pedantic about how you place/align mobile for charging to start
can be draw power from any USB source (mobile charger, PC, laptop)
doesn't come with own power supply, guess one less to worry about
Muting Koolpad:
The only downside was the beeping it makes when starting charging or if phone not aligned properly.
Fortunately this can be solved by muting the charger in simple following steps:
1. disassemble unit by removing 4 rubber legs and unscrewing 4 screws beneath them
2. this square structure circled in pics below is the beeper which you need to pop open carefully
3. now remove the metal disc in pic and close beeper without it
That is it, assemble the charger pad back and it won't make a beep
BTW I did tape the metallic disc to the inside of the charger before putting it back together, just in case!
Good luck!

I'll add some info on how to mute annoying beeper on Koolpad
plus where I got some of the stuff I used in the mod
Good luck!

Awesome. I'm looking through my stuff and I'll probably order some things and dust off the soldering iron. This is awesome. Thanks!
Thanks for the guide
Thanks for the guide just finished building the wireless charger, you where right the hardest part is getting the wires right for the pins.:good:
I for one think this is awesome and appreciate the work that's gone into it. Well done.
I actually just picked up a fixer upper HTC One X and was planning on doing this mod internally. Didn't think about using the contacts on the back of the phone. Thanks for that idea. If I can get this phone working properly, I will definitely be wiring it that way instead of directly to the usb port or components near it.

Well, I had the same thought initially but I have about a year on my warranty and don't want to void that just yet!
saw different (internal) mods on different devices plus how the newer Samsung devices offer a possibility for a clip on of a receiver card!
I am planning on doing an internal mod for my 1st gen N7, when I get the time.
Second post updated BTW with how to mute Koolpad wireless charger
thanx.
