and this tool:
So I would like to make a wireless charger for Acro s.
Simple step like follow:
1. Cut the very thin molybdenum disk to 2 small pieces.
2. Solder it to the coil output, this 2 mo-disk will contact with the charging point of Acro S.
This is the pic finished. see, I put 2 tiny copper clamper to make sure it have a contact.
3.Disassemble the back cover of Acro S. Stick the coil to it.
4. Put the back onto wireless charger test output voltage. everything fine here. output voltage around 5.3V without load.
5.Put cover back and put phone onto charger. WOW.It's working!
But soon I find something not right. It's not working well, the phone is keep doing like this: charing -> discharing ->charing .... and cycle like this .
I measure the output voltage, I found this: the voltage at first is 5V, after around 3 seconds it drop to 0V, then rise to 5V again.The charger doing this again and again. so make the phone go charging -> discharging ->charing ....cycle?
Has anyone can give some useful information?
reverse engineer your steps bro..
maybe you cut the disks too small in step1 or maybe a soldering problem

Good thinking. I will check my soldering, Maybe is really a contact problem. Things will go simple then.

This is very iffy, and DO NOT TRY THIS IF YOU CANNOT FOLLOW DIRECTIONS, I AM NOT RESPONSIBLE FOR YOUR PHONE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
This is your problem not mine, if you mess it up
My apologies for supersized images, but they get the point across.
Things you will need.
1. Battery bricked Photon/Motorola Device (x/x2/d/d2/etc)
2. A SPARE USB CABLE, NOT YOUR MAIN CABLE! (Don't be dumb!)
3. Your usb cable you use to to connect your device to your pc.
Directions as follows:
Step 1:
Splice your cable by cutting off the end of the cable (where you would input it to the phone)

1a: strip the wire about two inches so that white,green,red,black wires are all showing, pull back Green and white wires, as they will not be used.
1b. Strip the red/black wire so they look like below, then wind them up like so.
2. Pull out the battery in the photon.
2a. This is where this gets tricky, look the postive/negative logo's on the battery above the terminals, place the red in the positive terminal and the black in the negative terminal.
2b. Place battery in phone with wires connected to terminal!
3. Plug usb cable into your pc, then connect your usb cable to the phone, wait 2 minutes, and you should no longer have battery too low messages!!!
Remember when you disconnect the phone, UNPLUG THE BATTERY USB CABLE FROM THE PC FIRST OR YOU WILL **** UP YOUR PHONE'S BATTERY SENSOR!!!!
This will work on ALL motorola devices, and most phones period.
This is like jumping your battery from a car.
You're welcome for saving you money , this helped me out SO MANY TIMES.
Luckily I'm not in need of this but I was just wondering earlier this morning if this would be possible.. I figured I'd find out the hard way if it came down to it, but now I know it should work!
Thanks and excellent guide

Thank you in advance!
I was able to unmount the Samsung SGSII Cardock!!
As we can see, there is a resistor that enables the Cardock mode. Also, there is no connection of line 3 (D+) and 2 (D-) to usb female plug.
Now I have to read more the "Fun with resistors" thread to know if it is possible to mod the dock.
Does anyone know if it is possible to work like this?
The on/off key will be used to enable/disable the cardock mode. The yellow lines describes the new wires that i have to solder.
I decided to remove the smd board and plug a cable direct to the base. It's not the best solution bas it resolves my main issue (no USB data).
ok so i wanna add another charging port out the back for my in dash vehicle install. can anyone tell me how to add another charger without soldering into the micro usb port? i tried checking the pins on the back cover to see if any of them was apart of the qi charging and if so i would of just soldered into the pins on the mobo to the qi connection. but fot the life of me i cant figure out what ones are the charging for the qi as i cant find any voltage on them. unless im missing something? i attached a picture showing the pins i tried testing. they would be easiest if i just knew what one was positive/negative.
can anyone tell me where to solder in wires for another charging connection that isnt at the micro usb connector at the bottom? (i cant use that as the pins are just way to damn small for my soldering skills.)

quick update i found this, i found this image and it looks like the leads from the coil goes to the left of the cover but yet when i check for voltage when qi charging it doesn't show anything...
Why wouldn't you just use the wireless charging functionality that is already built in? Mount the charging pad behind it in the dash. I've seen a few people doing dash installs this way and it works great.

already tried that it works good until the tablet is fully charged, it quits accepting a charge until i unplug the qi charger or pull it away from the tablet and replace it.
I had an issue with my phone and resolved it, this is me sharing this particular error and solution.
First the Problem:
I had my ZL running low on charge and the next morning it would not react to anything.
pushing buttons (and a combination of buttons, like power+volumeup) did not work
connecting it to the charger
connecting to pc did not show the device or trigger a reaction (did not show up in device manager)
Solution A: Install a new battery (e. g. via IFIXIT guide).
Solution B (try on your own risk!!!):
Open the backcover of the device (i used the IFIXIT disassembly guide).
You dont need to remove the main curcuit board, you just need to disconnect the flex-cable of the battery shown in the picture below, the pink marker shows the battery connector (top right).

I bent the connector so that it was accessible with my universel charger, which looks like this
I connected the two marked connectors go to the + and - on the flex-cable of the battery and the charger signaled that it was charging the battery.
I guess you can use any universal charger of this fashion. Do not use your standard usb charger, it's dangerous!
After 10-20 minutes i reassembled the phone and was able to charge it normally, start it up, etc.
I'm no expert but this is what I think happend:
A completely drained and at the same time worn out battery did not allow chrging the divice. Mine was 20 months old. The phone controls the charging process I think, so maybe there was not enough power left for that.
I will be replacing my devices battery with a new one and I suggest the same I you have had the same problem.
I hope this helps

Hey,
some days ago Parkman sent me one of their E2 powerbanks for review so here it is now.
Let me first clarify that I am neither paid by them nor related to them in any other way.
Let's start :highfive:
Content:
The powerbank ships in a small box with all information printed onto it. Also it comes with a micro USB cable to charge it. There's no wall charger included but charging it over USB is totally sufficient. Despite the cable and the powerbank there are some warranty cards and instructions in the box as well.
Powerbank itself
The big advantage of this powerbank is that it is really small and has a built in output plug

It has 2200 mAH and I was able to charge my Blackview Alife P1 Pro smartphone (3000 mAH battery) to 64%. There are four LEDs on the powerbank which indicate how much juice is left - very handy! You can see them in the top of the image.
The only problem I had was that I could not really charge it in my pocket because the phone's USB slot is not centered but on the top left side. You can also see this in the image above. This makes the powerbank stand out a bit. On another phone I where the slot is centered it was completely fine though (see: http://imgur.com/qAWl96v.jpg) So definitely check the location of your USB slot before buying this powerbank
Conclusion:
Would I recommend this powerbank? The answer is "it depends". On the one hand it is really really handy and very portable. On the other hand 2200 mAH are nothing special nowadays. If you need to extend your phone's battery for one day go for it! If you want to go on a road trip over several days the capacity is definitely too low. I for myself use it every now and then when I am in town and my phone's battery is about to die.
