Building my own clock dock with battery charger - Samsung Galaxy Nexus

I managed to put together a google sketchup model of a galaxy nexus horizontal dock with extra battery charger. It has quite a ways to go but it is a nice start. I am going to get my buddy to print these out with his reprap printer this weekend and we will see what needs to be done.
Goals:
Use pogo pins to charge nexus
auto charge extra battery
have the dock hold the phone sturdy enough
*Update 2/16
I went to my friends house to get the parts printed out and lets just say it wasn't pretty. I haven't done any 3D printing before and it showed. I got some tips on what to change to get the part to work better in the printer and I will be spending some time this weekend fixing the model. The good news with this is that the new design should be extremely easy to change for different phones and phone shapes as all I will need to do is change the part that holds the phone, the rest of the dock can be reused.
Also I finished the schematic for the battery charging circuit. I will post a full schematic as well as a board layout when i actually put it up on a computer, right now its just a sketch in my notebook. The basics of the charging circuit is a National Instruments LP3947. This chip provides battery level monitoring which will allow the battery to charge to 100% and not overcharge or overheat. As for the power supply, I haven't decided yet. It is ether going to be a 2 amp plug or a 1 amp micro USB plug. The pogo pins are only rated for around 600mah and it is recommended to charge a battery at 500mah or less so I might just stick with using a micro USB plug to keep things easy.
* Update 2/18
I had to redesign the dock from scratch because as I stated before google sketchup isn't great for 3D printing and the model I tried to print failed pretty bad. I took my friend's advice and tried to chop it up into smaller pieces. I am going to print these out in a few hours and will post results this time. As for the schematic, I will get to that when I can. Getting a new model done was more important.
As you can see in the picture the dock is in a lot more pieces. Hopefully this means I can quickly redesign each part that is needed if something doesn't come out right in the print without having to print a whole new model. Also with more pieces anyone should be able to adjust this for any phone or case. The tray that holds the phone has room for another 3-5mm of thickness. I am not sure how much room there is width wise though.
* Update 2/19
Printed out a few parts, only two came out so I will give that another go when I have time.

Planning on mass production? Count me in for 1

Whenever I get it.working I will post instructions

If this had solid build quality I would definitely be interested. Especially in pogo pin charging capabilities.

If you decided to make one that fits with the cruzer a2 cases, Id def be in for this. Id even throw 1 in for ya if you dont already have one so you can get the stats right.

solid idea! hope you make it happen with all these delays on the official dock.

I'm very interested. Especially if it can incorporate pogo pins.

I have been thinking about this for a few days and I am a bit worried that people won't like the printed plastic finish. Since I am basically only making this for myself I am going for function over form. I only have access to a RepRap 3D printer and my own PCB etching stuff, so no nice injected plastic. If people are still interested in buying one instead of just building one from my instructions that I post when I'm done we can talk then.

Very much looking forward to this! It's similar to something I'd love to do myself but I graduated in December so I no longer have access to my school's rapid prototyping lab.

I'm sure there will be a lot of interest for this, since Samsung bailed, regardless of form.

Yea sorry about that, I ment my post that I made since it isnt possible to delete my post entirely I edited it to just ignore the one i made.
I love the concept and the thin profile of it. Good luck

Does anyone know where I can find the battery connector prebuilt? If I don't have to bend metal to make those tiny little clips that would make my life a ton easier.

Start there. From the best measurements I can take with my handy dandy metric ruler, looks like a 2.5mm spacing (pitch) between contacts and 4 contacts. Something like this, or exactly this, would work:

I went to the TMO store with the intent of buying one and changed my mind once I saw the size. They add a lot of thickness and they have a lump on the side where the USB connector hooks up to the phone.

could you go back and get a picture of it next to stock phone, so we can see the size comparison?
I'm really amazed at how reluctant manufacturers (HTC?) are to utilize the damn charging contacts on the side of the phone! Seriously, what moron thought it would be a better idea to have a skin with a huge lump on the side to house a USB plug instead of simply wiring three small contacts into side of the skin? Come on! Pull your head out of your a$$es HTC!

This is pretty much the correct answer.
I don't understand it either. The pins were one of the reasons I decided to keep this phone over the Nexus S. I assumed we would get all kinds of cool accessories that made use of them. Alas, nothing.
Depressing, indeed.
I was excited about this accessory, until I saw that giant lump on the side. It's pretty ridiculous, if you ask me.
The Nexus One had the pins as well, during the life of the phone the only two items to use them were the HTC desk dock and car dock. Manufacturers seem to forget about them.
Whats so great about the pins anyway?
Saw it and I'll pass on this too...wth were they thinking on this one!

I love my nexus dock granted it didn't come issue free (won't dock right if not seated properly) but it automatically goes to clock mode and I had it hooked up to my stereo where I streamed/listed to my music docked/undocked.

Pins are great, you don't have to plug in your phone to charge your phone. All you do is just set it to the dock. Now for pins on a car dock, it automatically goes to carmode. I just hope if tmobile makes a cardock they learned from the mistakes of the nexus ver and add a 3.5mm jack in the back.

The pins are larger, and can allow for greater amperage depending on the internal circuitry. The Nexus One car dock would charge my phone *incredibly* fast; it was awesome. It was the one charger that could keep up with (and easily surpass) the discharge rate of the battery when using Google Navigation.

Ive wondered about this myself. I have one (got it for christmas), and while my battery life has increased, it seems to be getting worse and worse, especially if I ever go without the skin (ie, to charge the skin and still be able to use the phone). I swear, I was in the car on the way to college and had half the battery drain in oon hour powerskin was depleted. Mind you, that skin lasted a good 7+ hours, but then my phone nearly died before i got to school to charge it.
this thing is quite epic fail. i dont even mind the bulge its the fact that it keeps charging the battery at all times which scares the crap outta me. price is cheap at 40 but still not worth it. returning it tomorrow.
My Review
I have had this power skin for a week and I overall Like it. One thing this doesn't help is from not shattering the screen.. Because I shattered mine day 2 I had this powerskin, but I overall enjoy it and I don't even worry about the battery anymore.
A trick and something I noticed to make it not to always charge your device is if you charge just the powerskin by itself and unplug it then put your phone in it. It will not charge your phone until you turn it on by pressing the button on the back.
If you need more battery juice and longer battery life I suggest you get you will notice a difference.
I dont even know which tmobile stores are selling powerskins for this phone
just call and ask. alot of stores have them cause of the cancer lump on the side of the phone lols.

Galaxy Note Crown Stand Dock Review

I wouldn't recommend the dock as a stand-in dock, where you plug it in on the go, or quickly. The phone is only supported by the actual USB plug! So I'd be REALLY worried about the port getting loose over time, so I'd skip that. I had that happen to my SGSII. But on the other hand, you can lay it down and it was made for this, too! So there is no need to worry about the usb plug getting loose. I really like it for this. Just look at the last 2 pictures.
I hope you like it! It's a decent dock, I guess. It's more of a stand now. Haha.

Am tempted by this dock... but don't understand what you're saying here. I mean... in the images it looks like there's a rear-support for the phone to lean against. Do you have to faff with this or something, or does it remain up, so you can just drop the phone on and have it lean?
Alternatively, does anybody have suggestions for docks that work with cases? I got the iGadgitz case (link), which I'm totally pleased with... it doesn't turn your pockets inside-out when pulling it out.

Tap it to the right or to the left, and it'll put some kind of strain on the phone's port. That's what I don't like. I have a dock that DOES support the sides, and still ended up busting the port. I don't use the inbuilt charging feature. I just put it in the landscape orientation and use a normal microusb, and that also allows me to grab my phone while I'm waking up in the morning and unplug it correctly.

Ah, gotya. Yeah, my Streak sits in landscape, with a fat connector, so never realised the difference with the Note and a tiny connection.
And bugger... your port has already been wrecked? So it's a real issue. Bah.
Mmm... not exactly swamped with options that allow for cases though, but don't think I can risk it since I've gotta stick with this baby for 23.75 months yet
That said, this thing does last an entire day, unlike my Streak... so maybe I'll just get a spider-holder or something without charge/usb.
I use the dock daily. I just don't use the built in charger. I turn it on its side and use the regular charger. I think the angle's great.
But this does make me miss the blackberry dock. Blackberry's have metal connectors ONLY for docks that will never mess with any ports . Fantastic idea in my opinion. Oh well. This is a monster of a phone! hehe. Sold my 9900 for it
Awesome.
Thanks for the info, I've gone a head and ordered one.
I guess it'll be safe on my desk, as the odds on knocking it are near zero. As an alarm clock though, I totally get you... I'd wreck it in a single day.
Ah, charging all day at work... I'll probably save a million* in electric bills.
*Ok, maybe $0.01 per month, lol.

[MOD][PROJECT] Pogo Charging Dock

I didn't want to clog/hijack THIS THREAD but the pin info and idea was very helpful. After waiting and waiting and waiting for official word of a charging dock that utilizes the pogo pins on the side, I've given up hope. And lets face it if you kill the usb port on this thing "you're screwed". so I really wanted to reduce my usb port usage and utilize a feature that comes with the device.

My material list is 8 screws, 46 gauge guitar string, a strip of 1/2" playwood that happened to be ripped down to 2 1/2" in my garage, usb cable, piece of flat 1/8" thick plastic and a tiny bit of solder. The way that I screwed/bent the piece of guitar string gives the perfect amount of spring so that when the device is set both are compressed and make contact with the side of the device.
This was very spur of the moment and took me a half hour to build. And it works brilliantly. Yes I could have spent more time on design and material type and getting proper pogo pins. But I'm lazy and intent of this thread is spark ideas in other peoples heads. So now this masterpiece lives on my nightstand and I drop my galnex in at night and wake up to a full charge in the morning without having to use the usb port.
**edit** The pic of the lockscreen is in landscape using the Team Kang AOKP rom.
good day.
THIS is what I love to see here. Ingenuity. Looks good to me. I am thinking of putting some docks together here this weekend. One for the nightstand and one for the office.

VERY awesome work. I love some hacked together ingenuity for sure, haha. I've had the car and desktop dock on order from Clove since December but I think I'll be cancelling the orders fairly soon and working up something on my own.

Love it, nice work. Like you said, you could get some cheap pogo pins off digikey, but I like the character of your design.

This is a decent, and probably relevant, read speculating on the function of the third pin on the Nexus One: http://forum.xda-developers.com/showthread.php?t=631508
I love this, but I got some questions I'd like answered before attempting this.
1.For those of us without guitar string, would a paper clip bent into proper shape work well too?
2. What cable is that, that you were using just a power cord or was that usb?
3. You said it just sits on your night stand so does that mean you cant transfer data to your computer?
Also a video just going over it more or perhaps some more pics of the back there would be nice (at least for me) to see what is screwed around the screw.

1. no idea, sorry. Check out the pogo pins though.
2. Thats a power cable, a usb would have a wire for data.
3. the pins don't transfer any information (well... the middle one does, but not anything useful to a pc) so transferring stuff would be impossible. (but thats what wifi is for)
This is beautiful and ugly at the same time.
One thing I would recommend is cutting out an area at the bottom of the phone so that you COULD attach a USB, OTG, or MHL cable if need-be. Perhaps that side of the dock could be shaped like a B, or notched to also allow access to the headphone port.
I would also maybe split out the power connection to a microUSB port to power MHL or other accessories. Or maybe just wire up a fullsize female USB to power another unit such as a bluetooth headset or whatever. It just would be nice to have a powered USB port just in case.
To the guy above, sure it may not look perfect but a coat of paint would spruce it up very well.
Overall A+
I might try my hand at something like this. I'm a cheap ass when it comes to buying crap for phones (since I go through them often). I have all the materials already with the exception of spare guitar strings but the paperclip idea sounds great and can be bent to size. I have some Poplar wood in my basement that would even look good with a heavy clear coat.

I am thinking of attempting this as well. Except I dont have the wood to spare for this, so I am trying to look for a generic stand on ebay that would be possible to modify to fit at the least the pogo pins and at the most everything you mentioned. Because it would be a MHL adapter built in and ready to go.
Nice Job! Very creative use of guitar strings in lieu of pogo pins! I might have to try something like this...

Lol! Soo tempting to make a duct tape stand HA! I so totally need to restring my guitar and I already have some new strings.... (yells at wife) HONEY WHERE'S THE DUCT TAPE!!
For those looking for generic stands, I saw some on ebay that were just acrylic kinda in an "S" shape sort of deal that looked like could hold the nexus fully and was pretty modifiable.
Although than running a particular rom, has anyone found a way to get the GNex in to landscape mode while on a dock? I did a quick search and didn't find anything. On my D1 I used a magnet placed in a particular spot to force it into dock mode.

and this is a simplified prototype to test fitment and other things.
it fits the GSM and LTE Nexus with a case on it. the touchstone goodies are inbetween the case and the phone itself. opening the phone was unnecessary.
right now the phone is a bit of a tight fit. need to get that sorted out and try again in a few days. also need to verify the touchstone will work with the gap i gave it. (.050ish)
look forward to hearing any comments you guys have.
looks awesome!

agreed really WOW shame i can't do such thing because don't have such machinery
are u charging via pogo pins or micro usb?
Only issue I see with this is that the placement off the touchstone would have to line up exactly with where you place the coil.
From what I see it wouldn't work on mine since my coil is much higher to avoid interference with NFC...looks very promising though!

Pretty limiting in that you've blocked off the phone's speaker and the headphone jack. Sure, some people use bluetooth for everything - but some don't. Just some food for thought.
Looks cool. Any way you can share a cad file of this. I drew a few up myself and I'd like to compare dimensions.

Impressive.
Does the thickness of the material interfere with the cam at all? IIRC it has a pretty wide view. That said, dude, it has a hole for the camera, good stuff
Let's start from the top
Charging through the pogo pins. charging rate appears to be around 750Ma, or around 40% an hour. It was good enough to keep my phone charged while tethered streaming a movie. So its good enough for me.
I realize I didn't leave any provisions for the internal mics or speakers to do their thing. Much less room for the headphone and USB port. I'm only making a few of these for me and some friends willing to conform to my apple-esque control over how their phone is setup.
The NFC works fine, planning on using an NFC tag to launch the car dock.
Not sure about the camera, I should check that...
T-Keith, PM me your email and I'll try and send you some files when I get it to a point where I'm happy (it fits kinda tight right now)
Thanks for all the kind words, I'll get some nicer photos up soon.
Thats just good stuff - would love to see this extended to a home landscape dock.
I'm confused about how/what is holding the phone in the dock.
looks awesome. You could start a Kickstarter to get funding. I want one!
Definitely looks promising. Great inspiration, I might see what I can come up with if I have some free time. This is just begging for some rapid prototyping fun.
I'd also love to take a look at your files. Great work.

Agreed! If you post up the cad files when you're done I can probably whip one up in my company's makerbot. I can try and figure out the cost and go from there. This is an AWESOME project!
Question.
If you've modded your case so you can charge using a Touchstone, haven't you already got magnets in there to hold the handset in place when using the Touchstone?
If so, then what does the plastic bit achieve?
I'm not trying to criticise, I'm just confused is all.
Did you ever make more progress on this? I use a touchstone in my car now but something to keep the phone a bit more secure would be awesome!

Most people are afraid to use JUST a touchstone in their car because if you hit a big bump then your phone could go flying. This is EXACTLY what I was looking to do, integrate a touchstone into a regular car dock so that you can just drop it in for wireless charge and not worry about your phone launching across the car when you make a quick turn. I think I'm going to try to modify an already made dock to fit the touchstone as the back plate, as I don't have access to a CNC machine or a 3D printer =(
EDIT: Sorry if it's a bit off topic, but I found a dock that looks like it'd be perfect to cut out the back and integrate a touchstone. What do you guys think?

Beginning the journey of Wireless Charging

So I'm really missing wireless charging after having stuffed it into my GS3 and the Nexus 4 obviously having it built in. So... being that I still had 2 chargers and 2 pads left over, I've decided to begin modding the Moto X after seeing there was quite a bit of room in the bottom of the phone under the battery cover when I was replacing the woven black with a MotoMaker back. Here's the pre-fitting photos. I had to trim some of the foam away at the bottom, and still need to trace where exactly to place the wires for the charging. I'm guessing I'll have to solder directly to the back of the USB port. Where it sits will be a perfect angle, and should not interfere with NFC at all (Yay google wallet!)

I'll be posting periodically with updates, although I don't know when I'll have more time as I have 2 infant daughters that demand much attention.
Awesome!
I've been missing qi charging as well, hopefully you get this to work.

Curious to see how this goes. Even though I am quite sure the results will be positive.
Sub'd
I hope you don't abandon the idea and keep us updated. Seems like a worthy project!
Go OP! I can't wait to see success with this, so that I may be able to do this mod myself as well.
Exactly what I was hoping someone would do. Hopefully this works out and is simple enough to do. :good:
Looks awesome, OP!
On a side note - where did you get the MotoMaker back? I'd like to change my back to a custom-colored one eventually too, but I haven't been able to find any backs online.

You can get them on ebay now. Been eyeing getting one but waiting for the wood backs.
Well this is awesome man...!!!!! :good:
Wow, god speed. I don't yet have a Moto X (still holding out for a wood back) but I'm so used to using those Palm wireless chargers on my current phone (SGS)! I have one at work and one at home on my nightstand. It's a perfect angle of inclination for my preference and the wireless charging works great. Are you having any problems putting the phone back together? I know they don't leave much room in there for something as thick as one of these chargers. And I guess if I eventually get the wood back that probably wouldn't make for an easy time getting it off :-/
I'd like to do this too, which coil receiver do you recommend?
Thanks,
Danny

The one he is using in the images uses the Palm Touchstone charger, you can find a bunch of applicable coils on ebay: http://www.ebay.com/bhp/palm-wireless-charging I am fairly certain that this coil will only work on that Touchstone and is not compatible with QI or Powermat.
edit: I also highly recommend buying some tiny magnets (I bought 1/4" by 1/32" circular ones) instead of the metal disks that are included so you can get it to snap a lot better to the stand.
thanks
Anyone trying this should aim to have the charging coil as close to the camera as possible, the antennas are all in the lower back of the unit and you won't want to block them at all.
I have been looking at some wireless charging options myself. One of them is a small pad that should fit under most soft cases, it has a thin ribbon cable with a very low profile micro usb connector on the end. The better option is something like that but integrated internally. I haven't opened a Moto X yet to see how much space there is. What is the maximum thickness we can hope to have, is there anywhere near 1mm if we remove the silicone pad?
Everything I am looking at is Qi compatible.
I have also been studying high-res pictures of the inside of the Moto X looking for possible solder points for power, doesn't look too friendly at this point.

There is plenty of room towards the bottom and the silicone is maybe a mm in the thickest area. Insofar as blocking the antenna, I've never had issues with my sgs3 or note 2 with putting the coil over the antenna. However, with regards to solder points, you are right. This is not going to be easy without fully disassembling and finding either the microUSB solder points or the charging circuits entry points from the microUSB. I may be abandoning this if that's the case.

Has anyone tried this (for the qi standard)? Thinking about giving it a shot.

That looks like it would be perfect to slip between the phone and a case, would bending it to conform to the back of the phone affect it's charging ability though? Or would it even be able to be bent?

So how would one check to see which of the 4 prongs connected to the ribbon going to the battery are the correct +/- terminals. I've been studying over the iFixIt.com images to come up with a plan and I think if I can get a random wireless charging coil from eBay then cut that ribbon to fit into the 2 needed ports for the battery ribbon, then the only thing would be size/fitment under the back cover.

It shouldn't matter. As long as the plug is in, and the pad is near the wireless charger.
This is kinda smart; can't believe this isn't widely known. I've never seen something like this.

Someone has to be the guinea pig on this.. I would love to be able to slide this under a case.
