I *think* that might work. I grabbed a set of (older analog) calipers to measure the pogopins on my LTE GNex and found some estimates. It looks to me that the pogopins are spaced ~.112" apart (from center to center) and are ~.042" in diameter. The pins you found on digikey list the spacing between each pin to be ~.100" apart (from center to center) and ~.042" in diameter.

With those measurements in mind, there would be some slight overlap of the outer two pins onto the plastic casing but the pins would likely still strike the connector on the phone.

Keep in mind though that a number of users have noted that the center pin is not used for audio. I have no personal knowledge of this but I am passing the info along. Apparently audio is passed via bluetooth to a receiver in the mount which converts it to a line level output that is seen on the mount itself.

(Also, I guess I cannot include the hyperlink you had because I am too new to xda)

Update: I stand corrected, as noted later in this thread the spacing is .118" for the GNex pogopins. Apologies for the misinformation.
[Samsung Galaxy Nexus] rotus8:
The GN pogo pin spacing is 3mm (.118"). The All the Digi-Key pins mounted in strips seem to be .1" spacing which I think will be marginal, or at least make the position of the pins really critical.

Charging at 1A

How would you go about charging the phone via the pogo pins at 1A instead of 500mA? From your photos I can see that your charger appears as a "USB" charger (500mA) instead of "AC" (1A).

With LTE and Google Navigation, 500mA isn't enough to keep the phone charged, so this charger mod would be inadequate for anyone looking to use their phone as a 4G navigator. However, if you can think of some way to charge at 1A over the pogo pins, I'm very interested. Perhaps that middle pin is important?
[Samsung Galaxy Nexus] bike2deth:
Great Writeup

Very well done write-up. I actually ordered some pogo pins about a week ago, just waiting for them to arrive. Originally, I was going to cut a large hole in the dock approximately where the pogos should be, and then fill that with a 2 part epoxy putty, and then push the pins through. The putty would allow for precise adjustment of the pins, and once it sets, should be as solid as epoxy. The putty would also serve to protect the solder joints.

I was not sure I could get the measurements for precision drilled holes correct, but after seeing your write-up I am going to give your way a try first. Thanks again.

A laser level. Awesome tool for so many things. Don't need to be a big "tinkerer" or "handyman" to make good use of them. Buy one, just hang a picture or two, profit.

No, the pitch (spacing b/w pins) is not 3mm like the nexus.

I've place a connector with 2.54mm pitch against the phone and I can assure you that there isn't enough margin for error for both outer pins to make contact. You will absolutely need to find a supplier for pins at 3mm pitch if you absolutely want to install pins in a connector block or you will need to use pins as individual components.

The car charger I used was >500mA, I can't remember what the exact current output it can supply is (it's in the car, used it all day with awesome results, but it's freezing outside). While I was waiting for the mount to come in I made a little jig with pins on it to test the electrical connection. I only used a 500mA wall wart with it but I'll check with a higher current output one tonight if I happen to have one (I own one, I just need to find it). I have a feeling that the phone only accepts USB level currents through the pins though (the touchstone mod through the pins also registers as USB). Other than screen-on w/ GPS it should always be able to supply more power than what is used. Even with GPS you're only going to lose a small fraction compared to using it without power.

I had the exact same idea at first. I thought if I could get the position right that it would make things easier in the end. If I didn't, my plan was to hot-knife out a small section and do what you are saying, didn't need to in the end.

I highly recommend people use putty/epoxy to increase the strain relief. Solder joints are for joining two things electrically, not mechanically. The more rubbery/flex the epoxy has the better. There are epoxies that even advertise this right on the packaging, definitely better than just a rigid resin that may crack.
[Samsung Galaxy Nexus] djras111:
I have hooked up the pins to a 5Vdc source and it drew 1A current
[Samsung Galaxy Nexus] hedaleth:
After some careful measurements, the VGN pin spacing seems to be 3mm as noted earlier. Here's a company making 3mm spaced pins:

They show distributors on their site, but have not yet called to see what/where to get these.

Hello,

Just dropping by to say hi and to let ya know that this thread has been featured on the XDA Portal:

:)
[Samsung Galaxy Nexus] haleybob1228:
Via the pogopins? I was only able to draw just under 500mA using the standard 1A AC charger (to a hacked up USB cable to the pogopins). I 'shopped together a pic here:
[Samsung Galaxy Nexus] bunklung:
Great work!

As far as the USB charging issue, 500ma is not going to be enough. There is a thread here:

http://xdaforums.com/showthread.php?t=1487676

There is a discussion about adding a software mod to trigger AC charging over USB. I suspect with the pogo pins, like MHL, there is no means to short the data pins to let the phone know to draw greater than 500ma.
[Samsung Galaxy Nexus] Knolly:
Excellent work on the mod, well done!!!

Just throwing it out there, your description of the mod completely misrepresents what it does. There are zero modifications made to the actual phone, this is a mod to the Verizon dock to add pogo pins. You say "but in the end it will make your Galaxy Nexus charge while in certain pogo pin compatible car docks," but what this entire thread is about is CREATING a pogo pin compatible car dock, not making the phone work in an existing one, since there is yet to be one released.

@OP thank you so much for gettin' the gears turning in my head. I don't use a car dock myself but the info from the OP sparked an idea for something I have been waiting for impatiently.

Another Pogo Pin part#

Measuring the thickness of the dock surface that the pogo pins will have to be mounted through, I get ~ 3.63mm. This is approximate because the inner lining of the dock is a softer, rubbery material, so its hard to say whether or not im compressing that lining any with my calipers.

With that measurement in mind, check out this pogo pin model on DigiKey:

DigiKey Part Number: ED8182-ND

MM Part Number: 0906-2-15-20-75-14-11-0

From my best guess, it looks like these pogo pins will be just the right height to mate well with the phone, with about 1mm of pogo compression. I have some on order and I think they will work beautifully. I'll post my experience when they get here, but I judging from the OP's pics, these should be very similar to the ones he used in this mod.
[Samsung Galaxy Nexus] ArcaneMethods:
Aw, c'mon. No one's bench is that clean and uncluttered. :-)
[Samsung Galaxy Nexus] ATHM50:
Proper DIY. Nicely done. I hope to follow your lead soon.
[Samsung Galaxy Nexus] BamaNZ:
How much would it take to get one of you handy guys to do this for me? I'm willing to pay.
[Samsung Galaxy Nexus] ellesshoo:
Haha, yea it's NEVER that clean, but I figured taking the pics was good enough reason to tidy it up.
[Samsung Galaxy Nexus] Franky_V:
Nice Work! :D I actually had a similar plan, along with also creating a custom mount in my center console, but one thing has been holding me back. How EXACTLY did you mount those pogo pins with the epoxy?

It's hard to believe, but not impossible, that your epoxy is going to be strong enough to remain secure by only adhering to the outside. I thought of making a small flat "bar" that held the pins securely and could be mounted via a tiny rivet or tiny bolt or weird wedge to the case. I just am worried that the pressure from the inside of the case, caused by the phone, will cause them to get pushed out with relative ease.

---------- Post added at 09:35 PM ---------- Previous post was at 09:30 PM ----------

I actually just had an epiphany as to how I could secure it strongly on MY dock idea, but I'm still curious how you did yours :-P
[Samsung Galaxy Nexus] mca312:
I ordered 3mm pitch pogo pins from Yokowo and they are perfect for this. (aligned perfectly)

I picked up the Verizon mount today, so hopefully I can have my faux dock this weekend.
[Samsung Galaxy Nexus] 4Pr3mier:
http://www.yokowoconnector.com/productline/pin3_3.html

So which "type" did you order?
[Samsung Galaxy Nexus] ellesshoo:
I put tiny bit of epoxy on the outside of the pins (NOT on the plunger) and then yea, sealed it all in from the outside. It's nice and strong, been using on my 1.5 hour commute (that's round trip) everyday. It's critical that only the plunger is sticking out into the inside or else the phone, when inserted, will almost surely put stress on the epoxy or worse, crack it.
[Samsung Galaxy Nexus] yzf600:
It's not faux if it works! And it sure beats the heck out of the vaporware dock.

Did you have to call them to order? How much was it per unit + shipping? I often find these electronic component companies hard to deal with when you only want < 5 items.
[Samsung Galaxy Nexus] Knolly:
Nice, can't wait to see how it goes!

Also if you happen to have any left over (since I know it's tough to order small components like this individually) I'd love to take them off your hands.
[Samsung Galaxy Nexus] mca312:
I got 2 of Type 2307.

I ordered them before I had the dock, so I had no idea what the thickness would be so it would sit flush. It is hard to measure the dock accurately, but if I was to get them again, I would probably go for 3413
[Samsung Galaxy Nexus] wookaru:
Due to some mods I have made on my car dock :), I can say with a fairly high degree of certainty that the thickness of the dock at the point where you would need to insert the pins is ~3.63mm.

The inside of the dock is lined with a soft, rubbery material, so its hard to say for sure weather or not my calipers were compressing the lining at all, but they were as close as I could manage to just resting on the surface.
[Samsung Galaxy Nexus] mca312:
Good to know. So it looks like type 3614 is what you would need to be flush.
[Samsung Galaxy Nexus] lindsche:
did you actually get the "charging (ac)" in the battery analysis or did you measure only the current via a multimeter?

i just cutted a sonyericsson charger chord that gave me "charging (ac)" via usb but gives me now only charging(usb) via the pogo pins.

before cutting another charger chord it would be nice to know if it's necessary to do anything else to have 1A via the pogo pins.
[Samsung Galaxy Nexus] karstensson:
do i need to make any hardware modifications to the phone or should it just work?
[Samsung Galaxy Nexus] chopper the dog:
No mods needed to the phone. It does take 6~8 seconds for charging to start.

good day.
[Samsung Galaxy Nexus] ellesshoo:
I think the delay you are referring to might actually be software related. My GSM Nexus running AOKP(4.0.3 based) has this delay but my wife's LTE that's totally stock charges immediately. I unrooted my phone back to stock and it charged immediately. I then reflashed AOKP and the delay returned.
[Samsung Galaxy Nexus] chopper the dog:
Wonder if that's premeditated and cause for delay on real pogo docks? If it is something that was introduced into the 4.03 source it would make sense. I attributed the delay to the device making sure it was seated and getting a constant supply of power for a predetermined amount of time before the charging circuitry kicks in. But tbh honest, my plywood/guitar string dock suits my needs perfectly and doubt I will ever purchase a real one if they do ever see the light of day. And if I ever get a case, I'll just make dock for "free" to the specs of the case.

good day.
[Samsung Galaxy Nexus] mslam02:
...also wanting to know if someone has gotten a 1v (ac) charge through the pogos from a car charger...

[Samsung Galaxy Nexus] mca312:
I contacted the local retailer through email here in IL
[Samsung Galaxy Nexus] ellesshoo:
Curious to hear how you guys are planning to implement strain relief for the pogo to wire connections. My dock from the OP is holding up fine but I've got the itch to change things a bit and that is something I want to beef up. Obviously it would be sweet if there were a connector plug to crimp the wires into that grabbed the insulation as well. Any ideas to share on this topic?
[Samsung Galaxy Nexus] strongergravity:
I am actually going to anchor the wire to the backside of my dock near the pivot-ball. That way it will take the stress. My leading way to do that is epoxy, but I'm still thinking as I await my pins. &*$@ Backorders!

Great work on the Mount!!!

Could you direct me in the right direction for the NFC tag info. (Are you using a app on the phone to program the tag?)

Like how to program the features you have on yours, new to the NFC stuff, the electronics part I have down!

---------- Post added at 09:51 AM ---------- Previous post was at 09:31 AM ----------

Is this like the tag that you used?

Unfornatuly I can not link to site because I have less than 10 posts...

Mifare 1K chip? 25mm

Do you have a link to where you got yours.
[Samsung Galaxy Nexus] ellesshoo:
I got mine a year ago so I don't remember where I ordered them. I believe it is indeed a Mifare 1k. Try tagstand.com or buynfctags.com. Both are reputable. I used NFC Task Launcher to write the tags.
[Samsung Galaxy Nexus] ellesshoo:
I just tried something with interesting results.

I plugged an AC charger into the USB port and as usual the phone reported "Charging (AC)". Then, still plugged in I put the phone on a touchstone (same as charging via pogo pins) , still charging AC. Finally, I removed the AC charger from the USB port and the phone still reported AC charging with only the touchstone.

I reversed the order, starting on the touchstone (USB charging). It remained as USB charging in the same way it remained as AC charging in the previous experiment.

Could be a quirk in how the phone reports charging or it could be real. I don't have time at the moment to test the actual current flow.

Thought this might be of some interest.
[Samsung Galaxy Nexus] machiz7888:
Wrong thread. can't delete. this is awesome stuff though :p
[Samsung Galaxy Nexus] toms73novass:
Thanks for the Info!
[Samsung Galaxy Nexus] En4c3r:
Thanks that is a great idea for the tags. I was wondering about this also.

I have also toyed with getting a female micro usb slot to add to the car dock. That might be a solution for your next modification as far as a emergency break point that you mentioned. I would try and insert it in the base somehow like the OEM samsung model that has never materialized, although then it would be tricky wiring down to the base from the pogo pins.
[Samsung Galaxy Nexus] ellesshoo:
I thought of that but can't seem to source a micro-B receptacle that isn't a SMD or through-hole component. Come to think of it, I've never even seen a micro USB extension cable in the wild (something that could be at least hacked up for this purpose). I didn't want to use a standard sized connector for it.
[Samsung Galaxy Nexus] En4c3r:
I saw some on eBay that were only around 3 bucks, but they were shipping from China so they wouldn't get here until the middle of March. Ones in the US were around $10. They might need some trimming to make the female side smaller or another way to look at it is to keep it the same size for stability.

By the way loved your work bench
[Samsung Galaxy Nexus] Jewremy:
Dunno if you guys saw this, but that shiny panel pops right off...
[Samsung Galaxy Nexus] Knolly:
Has anyone figured out how to disassemble the curved base? It has a screw under the lever but even with that out I can't get it to budge.

EDIT: Actually just figured it out! There are two screws, you have to open the lever to access both of them. One is in front of it and one is recessed behind it. Then you can just pry apart the whole thing. Should make routing wire neat for when I get my pogo pins tomorrow!
[Samsung Galaxy Nexus] VivianC:
Can you share a name and price? I'm in the Arlington Heights area.
[Samsung Galaxy Nexus] nomisunrider:
I did a quick search but did not find the answer here.

Does this dock fit a gnexus with a TPU case on? If so, i wonder if longer pogo pins could be used to enable a phone with TPU case on.
[Samsung Galaxy Nexus] burch:
The car mount from VZW probably will not fit a phone with the TPU case. In fact, it barely fit my phone with just a full-body Ghost Armor wrap on it. It's a really, really tight fit.
[Samsung Galaxy Nexus] wookaru:
I have has success with this tag:

http://www.tagstand.com/collections/mifare-classic-stickers/products/nfc_square_35mm_l

And using this program to setup tasks:

https://market.android.com/details?id=com.jwsoft.nfcactionlauncher

If you buy the NFC tag from tagstand, make sure to select the NDEF Formatted option. Due to a bug in Android (it may have been resolved by now, im not sure), the Galaxy Nexus cannot format the tags correctly, but tagstand will do it for you.

---------- Post added at 04:54 PM ---------- Previous post was at 04:44 PM ----------

DUDE! Thanks! I didn't know it could be popped off without damaging the dock. I now have my NFC sticker inside my dock, stuck on the back of that plastic piece. Looks so much cleaner now!
[Samsung Galaxy Nexus] VivianC:
Quick question on the NFC tag:

When you put the phone in the dock, does it only read the tag once? I've been meaning to try this but haven't had the time.
[Samsung Galaxy Nexus] 4Pr3mier:
If you are using NFC Task Launcher, the tag is read every time the screen is turned on and unlocked (whether by slide/pin#/pattern).

As far as being in the car dock, I guess you would have to keep the screen on all the time.

If anyone knows a way to prevent the tag from being read again, I would like to know.

My idea was to prevent the tag from being read again as long as the phone is still connected to my car's bluetooth. How can I implement this? Tasker?
[Samsung Galaxy Nexus] VivianC:
Tasker has a "Stay On" display function that will keep the display on if on USB power. There is also a function to set the screen timeout to 24 hours.

Thanks for the reply. Time to go play in the car!
[Samsung Galaxy Nexus] En4c3r:
If you go to the developers website for nfc task manager the bottom video on the home page shows you how to set a rate limit on how the tag is read. I think it will answer your question.
[Samsung Galaxy Nexus] En4c3r:
Just curious how the spacing, or pitch, of the pins has been working out for you if you have received them yet. I'm still looking at which pins to get

Thanks!
[Samsung Galaxy Nexus] toms73novass:
Thanks for the info!
[Samsung Galaxy Nexus] En4c3r:
I just ordered two micro usb type B extension cables for the dock from, usbfirewire. I was going to run a six foot cable from the charger to the dock and solder to the pogo pins but I agreed with the op about having a break point and also being able to take the dock out easily if need be.

So I plan on having one short extension cable and place the female port in the dock base and solder the other end to the pins. Then the other cable will be routed down to my cars charger.

I'll update once the cables arrive.
[Samsung Galaxy Nexus] En4c3r:
I received the usb cords last night and promptly put them in. I used a shorter 12 inch extension cable to run the female connector from the base to the pogo pins. I still haven't received the pins yet so I am still waiting on those.

I had to remove the support rib to make room for the usb wire. I then drilled a hole to pass the wire through the back toward the phone. For the life of me I cannot figure out how they wired the OEM charger by samsung that has never come out.

I had to remove this little support rib as well to make way for the female connector so it would sit flush with the bottom.

I modified the housing for the female connector so it would sit flush with the outside wall of the car dock.

I measured and cut a small hole in the dock for the female connector to fit through.

I started with my exacto knife to start a small hole and then used my drill to drill holes close to one another.

I then cut out the small pieces in between the holes and smoothed the rough edges out with my exacto knife again.

After that, I used epoxy once I made sure it would fit good. Here is a pic with the male connector plugged in.

Here the case is back together and the wire is ready to be attached to the pogo pins (which haven't come in yet)

All closed up and ready for pogo pins.

I added my NFC tag and it works fine on the back of the black plastic piece that says samsung on it. Now I am just waiting on the pogo pins to arrive so I can get this thing in my car.

BTW all pics taken with my GN:D
[Samsung Galaxy Nexus] Knolly:
AWESOME work! I'm waiting on some putty to finish off the area where my pogo pins connect then my setup will route through the mount similar to yours. Well done!
[Samsung Galaxy Nexus] ellesshoo:
Nice.

As far as how Samsung is running the wires on the mythical dock I imagine it is constructed differently than the vzw crap. Probably like the N1 dock where the wires travelled through the center of the ball joint and down into the arm so that it can be rotated without any restrictions or tangling.
[Samsung Galaxy Nexus] En4c3r:
That makes sense about the wiring now that I think about it. I just couldn't figure it out with that huge screw in the middle of the ball joint. I heard back today on the pogo pins from the manufacturer and should be able to get them and put them in next week. I'll keep you posted.
[Samsung Galaxy Nexus] Knolly:
I finished up my mod of this yesterday finally. My pogo pins were really short so it was nowhere near as elegant as I liked, as I had to cut away a lot of the case, but I used an epoxy putty to build up some support and I'm happy with the result, should get pics up tonight.
[Samsung Galaxy Nexus] En4c3r:
Nice, I just got my pogo pins tonight so I will put some up as well as soon as I finish!. What size did you go with?
[Samsung Galaxy Nexus] En4c3r:
Ok I'm confused. I have the wires ready to go and tested them but they won't charge when touching to the pogo pins. If I connect ALL of the wires of the male adapter back on and stick it in the bottom of the phone it will charge AC mode just fine. If I only connect the red wire and the big silver (jacket of bare wires around the color ones) to the male plug it says charging (usb). The red and black only do not even charge USB mode.

Update: The phone will charge USB mode if I touch the same two wires (red and bare) to the pogo pins (I didn't know it took like 10 seconds to register). Any ideas to get it to charge in AC mode?

Well at least the pogo pins are in place.

Many thanks!
