I just finished making this cable. It's a female iPod connector that splits to micro USB and 3.5 mm headphones plug. I was tired of everyone making just iPhone compatible stereos but never giving ever other phone a way of charging without a separate wall charger. If they have a iPod dock they could easily put USB on the device also. Anyway here are the pics of the first prototype I made. Works flawlessly and charges as A/C.

Tutorial
How to make an iPod dock cable
The first thing I did was buy these 3 cables.
An iPod dock extension cable http://www.ebay.com/itm/30069026148...NX:IT&_trksid=p3984.m1497.l2649#ht_2757wt_698 ,
an 3.5mm stereo cable http://www.monoprice.com/products/p...d=10218&cs_id=1021802&p_id=644&seq=1&format=2 ,
and a micro usb cable http://www.monoprice.com/products/p...=10303&cs_id=1030307&p_id=4868&seq=1&format=2 . I then cut the iPod dock cable in half. Set the female end to the side. I opened up the male end to verify the color of the wiring to which pin they were attached to. What you need is 5 wires from the iPod dock connector. You need is the wires for either pin 1 or 2( audio GND) , pin 3(Audio R) , pin 4 (Audio L) , pin 16(USB GND), and pin 23 (USB +5VDC).
Now that you know what colors you need from the male end of the iPod connector, strip back about 4 inches of the outside jacket on the female ends cable you set aside. What I did was twist the outside drain/ground mesh together then separate the 5 wires you need from the cable. I then took the remaining wires put them in a line and cut them on a diagonal starting at about an inch. This way each wire is shorter than the next. Now twist them back together and put a piece of heat shrink over them. Now you should have the outside drain/ground and the 5 other wires left. Now cut the other 2 cables however long you want them . I made the 3.5 mm cable about 8 inches longer because it has to reach the top of your phone and the micro USB goes only to the side. Now strip back about 4 inches of the outside jacket of the other 2 cables. Do the same think and twist the outside drain/ground together if the cable has it. Now you should have the outside Drain/Ground, red, and white wires for the 3.5mm stereo cable. You should also have the outside drain/ground, red, white, green, and black on your micro USB cable. I started with applying heat shrink over the drain/ground for the 3.5mm stereo cable. Now solder the newly heat shrunk ground from the 3.5mm stereo cable to the wire that was going to pin 1or 2 (audio gnd) on your iPod cable. Now solder the red wire from the stereo cable to the wire from pin 3 (audio R). Then solder the white wire from the stereo cable to the wire from pin 4 (audio L). Now grab the micro USB cable. Cut the wires for the green and white wires from the micro USB to about an inch and solder them together. This will all the phone to charge at full A/C not at USB. Then solder the red wire to the wire going to pin 23 (+5 VDC). Next solder the black wire to the wire from pin 16 (USB gnd). Last solder the drain/ground from the iPod cable to the drain/ground of the micro usb.
3.5mm Stereo cable-
Red- Pin 3 (audio R)
White- Pin 4 (audio L)
GND- Pin 1or 2 (audio GND)
Micro USB-
Red- Pin 23 (+5 VDC)
Black- Pin 16(USB GND)
White-Green(Solder together for A/C charging)
Drain/GND(USB)- Drain/GND(iPod)
I ended up cutting the wires to about 2 inches total length before soldering and applied heat shrink over all the solders then a larger heat shrink over the whole place where all the splices took place. I also staggered the splices to make that area as small as possible. I should have taken pictures but didn’t. If/when I make another one I will take pics.

I would purchase!
I've seen people make these before they are pretty neat
Sent from my Dinc... I mean Rezound
Is the rezound incapable of Line Out over usb?
Only thing I have ever been able to do over USB on any android phone is mass storage. So if you have any songs on your device you can sync through USB mass storage and use the controls to select your song on your device. But to do anything streaming, you can't do it through USB. Also if your using it as a mass storage device I believe it only charges at .5A. Doing it this way you can charge at 1A and still use all your music services including beats audio.
soooooo.... where can i buy one?
I haven't made anymore yet. If/when I do you will be first on my list. Maybe next week I could get to it. Kinda busy with work(50+ hours a week right now) and the kids baseball.

It's actually for omap4 Motorola car docks. That cable won't even charge a moto phone if not docked.
However..
It charges my gnex but no audio cause Samsung phones are designed to activate dock mode by a resistor in the cable itself.. Gotta love our fragmented Android universe
Dude, this is awesome! I am totally going to make one of these.
Thanks for sharing the information!
I bought one of these..... http://www.amazon.com/Audio-Adapter-iPhone-30-Pin-DocksFemale/dp/B005HZJ2MK/ref=sr_1_5?ie=UTF8&qid=1348774751&sr=8-5&keywords=3.5mm+to+ipod+adapter
Keep in mind that it only plays and does not charge like the cable the OP made.
Does anyone know if this will let you change tracks with the dock device or car stereo?

Avaiable from 20 Feb
It's nice, but looks too big for listening on headphones while traveling.
now that is what you call multitasking!!!
wow thats what i need!
Again it depends on whether using the headphone adapter stops the handset microphone working. It's the one bug in the Martin Fields adapter.
Has someone tested it and can tell whether it is strong and reliable?
usb adapter
I got mine 2 weeks ago, it sits in the car and does a great job. it IS well made and not cheap plastic. now if ony i can plug a usb stick/hdd into it

Yes I'm looking for an adaptor so I can plug in a normal memory stick (using the usb host function) can anyone let me know where I can get one of these (UK ideally).
usb host -- external harddisk
The 3 in 1 adapter is one thing...
The message about enabling HTC to be USB Host ... is another.
Where did you find the needed drivers / s/w for HTC to be able to connect to a usb mem stick. (Or external HDD, or my Creative Zen Vision:M)

i belive that we are limited to the hardaware....otherwise we could use the files from the UNI.
To those of you who have purchased this 3 in 1 adaptor:
Does the end which plugs into the Hermes have exactly the same shape as the port on the bottom of the Hermes (with all sides of the port at right angles except for one diagonal notch in the lower right hand corner), or is it a standard mini-USB plug with notches on either side of the plug?
The reason I ask is that I would like to be able to plug the HTC-designed cradle I bought from Expansys into a desktop speaker system, but the HTC cradle only has the standard shaped mini-USB ports.
Interestingly, the HTC cradle has two mini-USB jacks, one marked with the USB icon (for synchronizing), and one marked with a power plug icon (for charging). I wish it had a headphone jack too.
Why does HTC make it so hard to use this device to listen to music? How about an honest to goodness 3.5 mm headphone jack on the bloody device itself? How about not making us choose whether to charge the unit OR listen to music? I hope they don't wonder why the iPod is so successful, or why so many folks are interested in the iPhone...
Okay, rant over. Any ideas or pictures of the device side of the 3 in 1 adaptor (you could use the Hermes' built in 2.0 mega pixel camera!) from those of you who purchased it?
the hermes does not support USB hosting... just passthrough... therefore will not work...

I was wondering the same thing. This would solve a huge problem that I am having with my setup as well.

I presume this means that you would not be able to plug in something like a USB memory stick with some sort of USB Mini adaptor ?
Just thinking outside the box, not even sure what I would use it for if it was possible.
Mmm .... I guess transferring files to TyTN when there is no USB cable or WiFi available.
Guess what I really need to do is to get as USB adaptor for the Memory Card ...
Right Angle or regular mini USB
Just wondering if anyone who has bought this knows if this is a right angle or a regular mini USB on the end that plugs into the phone.
I have one of these. Its brilliant, well... to an extent.
It has the same non-standard usb shape as the HTC plug that goes into the Hermes. It has to, to connect to Charging, USB and audio.
I use normal headphones with it, works a treat.
I also have a car mount, and my little project was to use my 2.5" Wifi all-in-one disc/access point in the car (Its a Asus something or other). Use WiFi on the Hermes to connect to 80G 2.5" disc in the car boot, and play music using cassette adapter through the car stereo.
Only problem is, if I mod my car mount so this adapter is in it permanently (which I have done), audio from the phone is always diverted through the adapter, whether you have phones plugged in or not.
Which means I wouldnt hear TomTom directions unless I was using the Phone for audio (i.e. not use car radio or CD).
I have this splitter as well. I ride a motorcycle and this thing is great: it allows me to listen to music and use spoken instructions from TomTom for navigation at the same time.
However, I do have a small question. I'd like to have an 'activation button' and a noise cancelling microphone in the helmet. Anyone know if there's a headset around that offers this, one where I could just cut off the earphones??
By the way, has anyone tried hooking up both regular headphones and a complete headset? Does the TyTN/splitter allow audio to both at the same time?
OK, I just got my new adaptor (Stereo Headphone Adapter For ExtUSB 11 pin to 3.5mm) and I was thinking that I can't really charge the phone while using it. This dongle might be the solution. Has anyone tried it with this:

Why wouldn't you be able to charge the phone while using it? Bluetooth earpiece, regular headset, etc. all work fine while charging. Unless you mean 'on the road' when there's no wall outlet
I just made my own "car dock" cable based on the information over the "Fun with resistors" thread.
Basically I have a cable with a micro-usb connector that switch my phone to "car dock" mode, audio via usb/aux and charging.
CHECK THE 2ND POST FOR UPDATES, PICTURES AND A QUICK VIDEO.
WARNING:
This cable can physically damage/destroy your phone if made incorrectly.
If you don't have experience soldering electronics and small parts maybe you should not try this.
The usb cable will NOT work for sync/data - just charging.
I'm not responsible if you damage or destroy your phone/property and/or injury yourself or others.
Use this instructions at your own risk.
Parts that I used:
micro usb male connector (Digi-Key pn: 609-4051-ND)
619K ohm resistor (Digi-Key pn: RNF14FTD619KCT-ND)
6ft 3.5mm Stereo Plug/Plug M/M Cable (MonoPrice.com pid: 644)
1.5ft USB 2.0 A Male to Micro 5pin Male 28/28AWG Cable (MonoPrice.com pid: 5137)
I should have used a longer cable but that's what I had at home
This is the pin-out for the usb connector:

}
Preparations:
1) Cut one of the aux cable connectors and expose the 3 wires:
Yellow = common ground
White = right channel
Red = left channel
The left/right channel may be inverted, test on your phone before you make the cable.
2) Cut the micro usb connector from the usb cable and expose the 4 wires:
Red = +5vcc
Black = ground
Green = not used
White = not used
Soldering:
Start with the audio cable:
Solder left channel wire to pin 2
Solder right channel wire to pin 3
Do NOT solder the ground wire yet
Now with the usb cable:
Solder red wire wire to pin 1
Do NOT solder the ground (black wire) yet
With the resistor:
Solder 1 resistor leg to pin 4
Solder the other resistor leg + audio ground (yellow wire) + usb ground (black wire) to pin 5
Almost done...
Test all the connections for short-circuit with a digital multimeter
Triple check for the right cable on the right place, you don't want to put that +5vcc on the wrong pin, it will fry your phone!
Just finish it with some epoxy glue to make sure the cables won't break where you soldered them and some shrink tube for a polished finish.
You must go to Settings > Dock Settings > Audio output mode and enable it to have the audio-out working.
I will post pictures next week when I will make a new cable with longer usb and better finish.
The cable I have now works fine, it's just ugly...
I hope this info will be useful for someone

Hello all!
Thank you to all the people who rated this thread and enjoyed the info
After building my first cable from two different cables and finishing it up with some epoxy putty I started searching for a better and easier way to build this cable.
While searching on some Chinese accessories website I've found an iPhone USB/aux cable that would make this build easier and nicer.
This is the USB/aux cable from DealExtreme.com (item #34654):
From eBay I got this micro-usb connector with a "housing" (link):
The resistor is the same from the original post:
With this parts in hand I started by taking the iPhone connector apart:
With the soldering iron I removed the connector and with an blade I removed the cable "terminator"(?) so I could expose more wire and use my own "terminator"(?):
Using a multimeter and my "pro-mod" I was able to verify the cables and plugs.
All cables matched so I started soldering:
After checking for short-circuits and fixing the mistake I always make (I invert left and right channels) it was time to squeeze everything inside that tiny housing:
It looks nice but now let's test it:
Pictures are worth 1,000 words but a video is priceless (don't mind the music):
Great write up!

Nice write up. Very useful. Thanks
Awesome, gunna order some of these parts.
Exactly What I Wanted
This is EXACTLY what I was looking for!! Once I see a picture/video of it in action, I'll get the parts. Question is, are you going to make your own car dock for it? Or are you going to purchase a generic dock? I'd like something that I can slide the phone into easily (and have the phone be horizontal). I am curious about the possibility of getting Digital Audio out instead of Analog. You seem to be the expert, do you think that's possible? Thanks!
I'm 95% certain digital audio out is not possible, except maybe for MHL/HDMI audio output via the MHL adapter.
There just aren't any provisions for it.
Thanks guys for the replies!
I got some PM about selling the cable. Right now I can't do it as I don't have enough time to make a good and durable cable.
The cable I have is kinda put together with epoxy putty and some shrink tubes.
Today I tested the cable and it works fine on my car.
I just found some iPod/iPhone cable that I think can make this build be easier and faster, basically you will change the apple connector for the micro-usb and add the resistor. I still waiting for the parts to arrive to test this new idea.
As Entropy512 said digital audio isn't possible with this setup but I will look in to it in the future to see if it's possible to use the mhl adaptor just for the audio.
Tomorrow I will post the pictures and a small video from it working with my current cable.
Thanks once again for the replies!
This is awesome thanks!! If you can create a few of these I would definitely be in for buying one. I am hoping to replace my itouch in the car with the phone. I already have a nice dock thus just need a cable.

So digital audio out is not possible (that's kinda what I figured). But what about getting a USB->Digital Audio Out? I realize the kernel would have to support a device like this. I'm very new to the Android scene (less than a week). But I'd think that it would be possible. I can't post links yet, but it was a $25 USB->SPDIF device on Amazon. The reason I'm asking is that I'd like a way to eliminate the "road noise" (alternator noise) from my music.
And how are you controlling your music in your car? Do you have a remote for the phone? Bluetooth? Or are you doing it the "old fashioned way". LoL! Thanks again for your efforts!

You can use MHL->HDMI adapter then put in a HDMI->Digital audio converter to get the digital audio out without any modification to software. MonoPrice.com has both but I believe the later requires some external AC power.
I have an official Samsung car dock for my Captivate. After reading OP's post, I decided to mod that car dock. I stripe out the part that connects to Captivate USB port and contains microUSB socket for power and 3.5mm audio jack (it already has the required resisitor inside). Now all I need is some 5-wire microUSB male to female extension cable. This kind of cable is hard to come by but do exist.
I did some reading in the 'fun with resistors' thread, and while this mod looks to work, I'm worried about the lack of sufficient charging amperage. It seems that in order to do "high current charging" you need to short pins 4 and 5 on the micro USB plug. Well, those are in use by the audio output. This seems to be a _major_ design flaw in MHL. So basically, you'd have to turn off anything you don't need (WiFi primarily, maybe Bluetooth if you don't want integrated hands-free with your car's head-unit) in order to get an actual charge. So maybe this cable with a Tasker function to turn off those services and activate your Car Home app.
Please take what I say with a grain of salt. Again, I'm very new to Android and I'm probably wrong.

The device assumes that a proper high-current supply is present when a dock or MHL ID resistor is detected.

In theory, I believe the device has USB Host/USB OTG support - but I know very little about enabling it. It MIGHT be possible to get USB sound cart to sort-of work - but getting the phone to route audio to the "new" interface would be extremely difficult.
I used to deal with Digikey decades ago .....
Are they selling "onesies" of parts now or do you have to buy multiples?
The items that I've listed you can buy just 1.
They have other items where the minimum order is 5000.

Mouser is usually a bit better about minimum order quantity though - I think digikey improved over the years in that regard.
Usually Mouser has their quantity price breaks earlier.

I can confirm this works.. just finished building it tonight and functions fine.
Have fun!
This guide is based on [GUIDE] The $6 way to charging your EEE Pad on your computer, taken one step further.
DISCLAIMER! YOU DO THIS ON YOUR OWN RISK! IF YOU SCREW SOMETHING UP ITS NOT MY FAULT!
This guide will show you how you can charge your TF101 from the PC, while also have it connected through USB allowing you to sync etc just as you normally would.
Its possible this method also works on the TF201, but I dont know for sure.
Difficulty: Pisseasy
Parts and tools needed:
A female molex connector with the yellow(+12v) and black(ground) wire. Where you get it from doesnt matter. I stole mine from an old pci-e -> molex adapter.
Headphone extension cord (or any other 2-wire cable you can use as a connector)
USB extension cord (2.0 works fine, no need to get a 3.0)
Tape (or if youre not as lazy as me - a soldering iron)
Teeth (or a wire-stripper/cutter)
Carpet knife or similar
Multimeter, not necessary but recommended to check if the power is correct before hooking it up to your tablet.
Ok, lets get started!
Id like to apologize for the rather vague images. I took them after I had actually built the cable.
Grab the male end of the headphone extension cord and cut it, leaving a bit of cable (I left around 20cm)

Next, grab the USB Extension cord.
I wish I had a better picture for this, but its not that tricky. What you want to do is remove the cover around the shielding, remove the shielding and exposing the 4 wires.
Once thats done, cut the red and black wires, leave the green and white.
Strip the red and black wires going towards the female end of the extension cord.
Connect the white and red wire from the male audio extension cord to the red and black wire on the usb extension cord. I suggest you attach red to red, white to black. It doesnt matter much though, but do remember how you connect them.
If done correctly you should end up with something similar as the picture.
Grab your favorite roll of tape and secure the wires and you should end up with this
Gratz, the first part is complete! Now to steal some power from the PC.
Grab the remaining part of the audio extension cord, which should contain the female connection.
Grab your molex connector (In the picture, I have already stolen one of the molex connectors)
Now, strip the yellow and black wire on the molex connector, and strip the red and white cable on the female audio cord.
Connect them the same way you did with the usb cable (if you followed my example, yellow goes to red, black goes to white).
Excuse my extremely dusty PC... Im ashamed :x
this might be a good part to route the molex-female audio cable inside the PC so it reaches outside.
Once thats done, simply hook the molex connector up to a free connector in your PC
And finally, grab your usb-male audio cable, connect the male audio with the female audio and plug the usb end into a free usb port.
Finally! Hook up your original TF101 usb cable to the female end of the USB cord and enjoy being able to charge your tablet while transfering files!
WARNING! Do NOT connect anything but the TF to this cable. 12v will fry any normal USB device.
Troubleshooting:
If your tablet does not react when you connect it, you have most likely gotten the polarities wrong. Simply switch the place of either red/black on the usb cable, or yellow/black on the molex connector (this is where a multimeter is handy).
There are many ways of doing this, I chose to do it like this because I had an audio extension cord lying around, and I wanted to be able to detach the cable from the PC.
Basically all you have to do is cut the red and black wire from the usb cable, and hook them up to the 12v rail on your PC instead of the 5v rail USB is running on.
How you chose to do this is, in the end, up to you.
Additionally, if you replace the audio jacks with some other more standard DC plug, you could use this cable to charge your TF using any DC adapter that provides 12-15V.
Once I get a USB Extension Kit for my TF, Im going to try to add a charging port to that as well. If I succeed in that, Ill post another guide covering that.
If you found this guide useful, hit 'thanks'
I'll try it when I'll have the time =) Nice tutorial!

Son of a.... Youre right... Ill fix it...
edit: Pictures should work now.
Heres a "benchmark", or whatever you want to call it, showing roughly how fast the tablet charges.
Note that the screen was turned on all the time, and I used it occasionally.
It does indeed charge slower than the real wall-charger, but thats not strange considering theres a 3V difference.
The wall charger charges an equal amount in roughly 1:30h, during the same usage.
Edit: I forgot to mention, if you use this method you can extend the charging cable easily by just hooking up an addition audio extension cable
Do beware of voltage drops though, the cables aint exactly thick. My cable is around 4m total, and I get a voltage drop of ~0.5v from the molex to the female usb plug.
I tried this and got to the extention cable section, I totally butchered my usb extension cable and gave up since I don't have another. Great guide though! I just can't cut and splice without completly failing and breaking things -_-

Dont know how you managed to butcher the cable though , you just need to strip 2 wires (or 4, if you decide its easier to cut the white and green too), and wire them together.
Hello all,
I have the following problem: The USB connector side of the standard charger cable for my TF101G is damaged beyond repair. The wall wart is fine.
In my naivity I bought the standard USB adapter (namely this: http://www.amazon.com/Transformer-T...INXQ/ref=sr_1_6?ie=UTF8&qid=1336838294&sr=8-6 ) believing that a "standard" USB Type A male -- male cable to connect the adapter to the wall wart will do the trick.
After finding it doesn't I browsed (quickly...) this thread http://forum.xda-developers.com/showthread.php?t=1087321 . It seems that the adapter is using some different wiring...
I tried this with both USB 2.0 and USB 3.0 (male - male) cable between the wall wart and the USB adapter to no avail.
Question is simple: Can I use the adapter I bought -- via some easy modding of the USB cables if needed -- to charge the tablet (and keyboard) ? Or I simply need to buy another charger ?
Thanks,
Florian
No, the pins used for charging is not in use on the adapter.
You can quite easily fix your cable though, if the 40-pin connector is still intact. Its just 4 (ok, 5 actually) wires.
If its only part of the cable thats broken, you can just cut the cable and then cut a USB3 cable and solder them together. red to red, black to black, white to white etc... the 2nd red wire is supposed to be attached to pin7 of the usb3 cable. I dont know the color of that though.
The wall wart outputs 15 VDC @ 1.2 Amps when the TF is detected. If not, it will output the standard USB 5 VDC @ 2.0 Amps. Any voltage less than 11 VDC will not show the tablet charging.
A USB port (5 VDC @ 0.5 Amps) will charge with the screen off at a rate of 3% per hour.
An iPad charger (5 VDC @ 2.0 Amps) will charge with the screen off at a rate of 10% per hour.
If you are looking for a charger, it will have to output between 12 and 16 VDC across pin 1 and 4 of a USB connector.
You can make your own, or try to find one. Dynex makes one, or you can check some stores. ASUS sells them online, as do some other vendors. Depending on where you are located some users may be able to help you find one.
There is plenty of info on the forum on DIY chargers and such. Here is one thread:
So you can only trickle charge without ASUS charger?
or you can just build your own pc usb charger (see link in my sig)
Thats my charger just went tits up aswell. 3 days of gtee left! Tried freezer but no joy. Looks like its outputing something by the indicator on the tf itself but % still drops, dock indicator light doesnt come on.
Cables ok as pc installed drivers etc when connected.

Sounds like mine... it refuses to send 15v anymore, it only sends 5v.
Im going to rip mine apart, when I get some free time, and see if bridging the connections will help kick it into 15v mode again.

Welll...Tbh I'm not so sure I want to take the knife to an USB 3.0 cable....
If you look at the attached pics of the (damaged) connector you'll see the Red & Orange cable (still) soldered to Pin 1, the Shielding was (seemingly) connected to Pin 4, while on the other side (the "top" of the connector -- see 2nd pic) i have the Yellow Wire... well, not sure where ...Shielding ? Also, unclear where this yellow wire goes..
Anyway. My "problem" is that
1) Bought the USB adapter in vein (stupid, $45 mistake). Anyway, lesson learned.
2) I still isn't clear to me on what wire has to go where on the USB 3.0 side and I don't really want to take risks in frying any part (the tablet or the wall wart...)
Thanks anyway. Still looking for alternatives / safe way to reconnect this...

Not to throw a wrench in the works here, but I have a cable that installs drivers and functions just fine when connected to computer, but will not charge from either of the two wall adapters I own. Another cable I have will work with both adapters.
TF101 Megatron 1.0.4 Guevor test 17c
I bought one of these 2m cables from ebay and they work fine, you may find cheaper but this one does work and its longer that the original which is a bonus.
http://www.ebay.co.uk/itm/ws/eBayISAPI.dll?ViewItem&item=110837341306&ssPageName=ADME:L:OC:GB:3160
Edit :- I also have a 3m USB3 cable which I can use as an extention to the existing cable (or the 2m one above) so I can sit quite a way from the plug socket without a problem.
Spot of luck.....Asus tf came in to my store to get sent back for repair. So my tf is now happily getting a charge from the borrowed adaptor until ups pick it up
My charger was picked up yesterday and is currently tracked to Germany. Just as a tip for anyone - rma your tf yourself! Don't take it to the retailer to do it......Asus are hopeless with the retailers and seem to think its OK just to string it along knowing the retailer will take the flack.

Spot on m8. It was the cable. Charger was returned back to me today. Really good service despite the bad rma experiences for others.
Does anyone know where you can get a us outlet snap on plug for the stock charger? I just traded for a tf101 and one of the prongs is broken..

same problem
My kids did tear my cable and I have the white, yellow and green wires to reconnect. Is your sequence right? ?I mean is yellow connected to pin 7/15 volt contact?

So here is my plan, and I just wanted to run it by anyone who might be more tech-savy out there than me.
My plan is this (or see graphic)…. To Hard wire a USB charging cable into my vehicles electrical system. (All hidden under the dash) I mainly want to go this route because in the end, the biggest part of this fabrication would be the size of my pinky finger and cost me a total of like $4 for the fuse tap since i have the rest.
So what I will be doing it, taking a Mini (ATM) Fuse Tap and plugging it into the already present radio fuse slot. I’ll then wire the 12v Output of the fuse tap to the input of a 5v Regulator. I’ll ground the regulator to some random metal surface. Then I’ll wire the 5v Output on the regulator to the positive line of a cut USB-A to Micro USB cord. I’ll short out the USB cord’s data wired so the phone thinks it’s charging with AC power and pull the full mA. I’ll ground the negative of the USB cord to the ground post of the voltage regulator and call it a day.
I have considered an alternate route to this…Which would be similar in being that I would use a fuse tap and add in an additional AUX Charging Socket to that line, and adding something small like a giffin USB charger to the Charging Socket, followed by the USB cord. But I am inquisitive and experimental (as long as I can make sure it’s safe first) lol. So I want to give this way a try before I do that one.
Attached it a picture for easier explanation.

Sounds interesting, but I would go the second route with wiring in an aux cig lighter power port to plug in a small sized USB adapter. Lots of 12v sources under the dash and you could put this anywhere, and run a usb cord from it.
Question, why not just use the cig lighter that is already in your car?
Because what I want to do is get a window mount for the phone and mount it, then also supply a power cord to be used only for that mount. I don't want a cord strung across my dash, so I'm going the build a new power source and stuff it under the dash method. Plus I still want the full functionality of my pre existing aux port.

Oh hi! MECP certified car installer here. Why not just buy a car charger and a second power socket, fuse the positive to a constant or accessory source, and ground the negative to a good source of metal, then plug in and tape up the two pieces? The way you're doing it is way too messy and complicated

I must say that I agree with bigred on this one. Sounds like a great learning experience/project. Sometimes, because one way is simpler, doesn't necessarily mean it is the correct way to do it. Bigreds idea seams to be a cleaner final product, with more secure connections. My .02.

Thanks, I broke down and built one. Works out pretty good and provides a steady 5v of what appears to be clean power.

Some people might think that it is messy and complicated, but i find it easily customizable (contrary to messy, and not complicated).
I have done this type of thing in most every rig I've had over the past 10 years, about 4 or 5 I think. I have two reasons for doing it, one is to reduce clutter from the cable across the dash and the other is to leave the existing 12v outlet available for passengers/guests/other accessories.
I would agree with most of the other comments here about installing another 12v socket under the dash. This is what I do, I actually put two under there, leaving one open for future applications. This is more versatile and can be adapted to future devices more easily. All you have to do is plug in the necessary car charger under your dash and run the cable through the defrost vents and to the car dock. I just got done doing this with my wireless car dock in my service truck, new GMC 2500HD, worked out great and I still have two free outputs, one for guests and one for my laptop charger.
But, to each their own and if you already have the necessary parts as you mentioned, then why not. I'm certain that mine cost a lot more than $4 to setup. $9 for the double 12v outlets and $10 for the Palm car charger with usb cord(they push a full amp for fast charge) and I guess $2 for shrink tube and connectors.
