Check out my ghetto dock!

Ever since I got my EVO I've been wanting to get a dock, as I'm just a dock sort of guy. Nothing like getting home and not having to fiddle with a cable, just slam the phone down and be done with it. That and being able to see my screen from my chair or across the room is sooo nice. However, I use a case (the innocase surface II,) and have since launch day. I do not like having to take my phone out of my case ever if I can get away with it. Unfortunately, I've only seen one premade dock that works with a case, the innodock jr, and frankly- that thing sucks. It's expensive, ugly, and not even made for this phone in particular. So I've waited, and waited... and finally decided to make my own.
So I built this "thing" on top of some weird folding cradle I got from Bed Bath and Beyond for 10 bucks. Don't buy this thing unless you plan on modding it, it looks cool as it has a built in USB Hub and comes with a micro/mini USB cable, but frankly it kind of sucks as a cradle. It's supposed to have a nonslip surface the phone sticks to, but it doesn't work at all for the EVO with a case, probably because it's so heavy. But since it's not useful otherwise, I used it for my base. Nice thing is it does fold up and have a couple different angles you can set the phone at, which is kind of useful now that the phone actually stays on it at any other than fully folded up.
I then made a shim to hold the charging cable at the right spot out of some aluminum from an old hard drive casing. Nothing pretty here, just hacksaw'd it up and did a bit of filing. Goopy glued the charging cable to it, and epoxied the shim to the cradle. I didn't want to epoxy the cable itself to the cradle in case I want to remove it later, that and I wanted it to have some small amount of flexibility. I used the dock like this for a few days, but the phone didn't like to stay aligned all perfect like, so I epoxied the spacer bit on the other side on earlier today. It's just another piece of aluminum I cut and filed up to kinda fit the contour of the bottom of the case. Phone fits beautifully now, or at least as beautifully as something held together with epoxy can look.
Figured I'd throw out how I made my monstrosity to help anyone else do the same thing if they wanted to.

Good job. Makes me want to build something.

Lol, it is ghetto as advertised.
I'm sure it works great though, and you should be glad you made it!

You pulled off a mcgyver there my friend...

Yeah, its actually my second attempt at building a dock. My first time I tried to make it out of lego, but I had trouble getting the microusb connector at the right angle and getting it so the whole thing wouldn't just fall apart when I pulled the phone off.
If I had the equipment to make it, I though up a really sweet dock design made out of bent and folded 1/8" aluminum sheet, but alas I do not. You can find PCB mounted right angle microUSB connectors with a small amount of built in flex that are much better suited for docks than using an actual cable, but using one still requires something to build it into.

Idea for alternative charger connector (updated 3/7)

There have been a lot of complaints about the flimsy connector for the Xoom charger. I also think that it is a very poor design at most. The metal pin is too long, the plastic part is poking out too much etc.
I am no engineer and also bad at drawing but I attached something that I think might work. If anyone feels like they could produce a prototype that would be awesome!
The small magnet might or might not work. If you look at the area where all the connectors are you will see a small metal plate that could probably be used to anchor the connector magnetically.
Any feedback is appreciated (even just to say that I am full of sh!t!)
UPDATE: I added an alternative design using the two metal connectors for charging and a silicone plug to keep the connectors in place. A magnet will give additional stability.

It charges my Xoom very fast. It is still working and has not caused me any issues. If it breaks, I will come back here to *****.

I was just referring to the connector but thanks for the warning

So was I. The stock one works fine however, alternatives are great as well. I just do not see a need for one personally. Others may.

Yeah, the stock connecter scares me. I like your design though I'm not sure anyone here has the means to develop and sell it. I'm hoping maybe someone may find a softwear solution to charge via the USB micro port. What do you guys think, possible or no?

I like it! i think its a pretty good idea. Wish i knew someone who could create one. I would buy it. stock one scares me

how the F do magnets work?
anyhow, yeah really good design. I would buy that too.

i just turn it upside down while charging it.

I would buy one of those

I have to ask, why you would use that connector at all if you want to redesign a magnetic charger? Why not use the same priciple to connect it to the two plates on the bottom next to the hole for power?
As someone who repairs laptops for a living, this was the single most troubling design aspect of our new toy. It looks like it will be far to easy to damage the internals of this device with the default power cable.
It would make more sense to use a breakaway magnetic connection that makes contact with the two metal plates. I have not looked in to it too far but it would seem that the docs use this and the USB in them is strictly for audio out.

I was actually wondering if the metal plates would be used for dock charging. Since I don't own a dock I can't check. But if it is then yes, the charger should be attached magnetically! Thanks for the clarification. I'll try to design more options

My only complaint with the xoom, honestly is the charging system.
For starters, I don't see a reason to not allow charging over USB. Sure the voltage would only be 5v, and it would take considerably longer, but the option would be nice. This isn't to say I want to do away with the 12v charger, because the speed at which it charges is lovely, just the option for the other.
Secondly, the needle-like connector screams, "I want to be broken quickly!" Was there really a need to make the connector in that type and size?
Thirdly, the placement of the charger port is hideous and impractical. It's dead center at the bottom. I rarely use my xoom flat against a surface. I purchased the display portfolio that motorola made. The charger port is not only a hinderance to the utilization of my portfolio case, but is also covered at all times when using the case in any manner that motorola designed it. I'm sure this is simply a brain-fart on motorola's part, which happens to everyone and is understandable, but is there a reason the charger port couldn't have been placed on one of the sides of the device? I would say preferably the left hand side, as people are less likely to turn the device to sit on that side.
I'm not simply posting this to complain, just express my thoughts on the only true fault that I feel the xoom has. On that note, a 90 degree *honestly 180 degree by the design sketch* connector would be lovely, IMO. It still wouldn't be usable with the portfolio case, but it would allow someone to angle the xoom without fear of breaking the charger off inside it.

The two metal plates are indeed for charging on the dock. It takes away the need to use the stock charger on the needle tip. Just plug the charger into the dock and set the Xoom on it. I charge this way every time.

Only problem is that's a $70-$120 solution

Why even have the plug then and just use the metal plates?

The plug would add additional stability so that it doesn't come off so easily. Not sure how strong you could make the magnets. As I said, I'm no engineer

Makes sense, maybe a smaler nub though haha, otherwise I like the idea

Apple has a patent on the magnetically attached charger. Perhaps this is why motorola went the direction that it did.

DIY Wireless Car Charging Cradle?

Guys,
Has anyone here cracked open a Qi wireless charger and modded it into their existing car cradle?
I got one for that purpose and it's a little too big (a little bigger than my Nexus 5), so I cracked it open. Now I'm looking for ideas on what I can use to encase it.
These things have a ton of wasted space inside, so I know I can make it smaller somehow. Please chime in with any ideas you might have. Thanks!

What brand is that? Might end up buying one and modding one for myself as well.
Also what are the exact dimensions? it looks to be about 5''1/2 X 3''

The dimensions of the whole thing inside the black case are: 5 3/4 X 3 1/4 inches.
The board is 1 1/2 (plus 1/4 for the usb port) X 2 1/2 inches. The round part is 2 1/4 X 2 1/4 inches.
Together they are about 3 3/4 (again, plus 1/4 inch for the usb port) X2 1/2 inches. This is if the board and the round part are laying inline.
We need to consider that the round part can be folded around the other side of the board. Then the dimensions are even smaller than what you would get if you purchased one of the round "puck" ones. Folded, the dimensions are now: 2 1/4 X 2 1/2 inches.
I purchased mine on Ebay. http://www.ebay.com/itm/2-Color-Qi-...l_Phone_PDA_Chargers&var=&hash=item2c76d04857
It cost about $17.00 shipped from New Jersey.

Subscribing to this hoping for some interesting ideas from all the modders on this site. Would love to see a way to hook it up with a magnet in a puck shape that I could just sit it the car, place it on the charger with enough of an angle that I can see it while driving, and go.
This is how I had my old wireless charger for the Palm pre. Was nice because it was just strong enough to hold the phone at about a 45 degree angle (upside down) making it very easy to see. That is the thing I miss the most about the pre.

have you in your car those "typical american" cup holder between the front seats, nearby the gear shaft?
why don't try to remove and put the charger there?
I have enough space in my 2007 BMW 3 series just there, that's a cool idea
using fiberglass or some other filling materials to smooth the charger plate in the empty space

That would be a good idea but it makes it tougher to see when using GPS. I would have to look down away from the road as opposed to being on my dash with a quicker glance.

I was thinking of trying this same thing. I have this cheap mount from Walmart which I'm going to attempt to modify. I also have an extra one lying around in case I mess it up. I was looking at the charger in this thread, it looks like the board may be a bit smaller.
My plan is to just kind of dremel/drill/sand out a hole in the plastic of the mount, pop the charging coil in, and then cover it back up somehow. I'll let you guys know how it goes!

Ok, so I uncoiled the wires a little bit and folded the coil over the circuit board. you can see how small it makes the whole thing. This may be the way to go for me. That would make it smaller than my phone so it can fit under it in the car mount.
Im considering magnets, but if I make it this small there will be no room for them. Plus because it will be inside the car mount, I don't think Ill need them. We'll see..

Here is my 'beta' version I did the other afternoon since I happened to have the parts just laying around...
Using this charger (pretty sure same as OP) with the iOttie XL and these magnets.
Going to make an improved version that is more compact now that I know what I'm dealing with. Will definitely document the build of Ver. 1.0.
Changing up the charger and magnets, but keeping the iOttie XL. Using PlastiDip and Sugru for final appearance.

You guys stole my idea! lol. I posted a thread similar to this about a week ago. Didn't get very far though haha.
found a few items on ebay similar to this:
http://www.ebay.com/itm/Qi-5V-Wirel...S_Cell_Phone_PDA_Chargers&hash=item1e8334dd2b
I wonder if you were to solder off the qi coil and resolder one of these instead, if it would work? Reason being, because they are so slim, and I assume at 1mm thick, and being able to place in a phone cover with no noticeable difference, if it would help make it even thinner? im thinking at 1mm, perhaps it would be flexible as well?,

Buy the official nexus charger if you can. The magnets hold the phone in place just fine, been using it the past few days. The ideal solution in my opinion.

So to clarify, you are using the official Nexus charger as a car dock, and the magnets are strong enough for the phone not to fall off? Are you using a case?

Subscribed.
I have ordered an iBOLT xProDock (BB Z10) from Amazon.ca for 19.95, and a QI puck from ebay.
Not sure if there's enough space inside the xProDock body to accomodate the coil - we'll see.
amazon.ca/IBOLT-xProDock-Holder-Mount-Blackberry/dp/B00BPAHNQI

I might actually take the whole charging coil out of the case, but will need something to encase it with. Maybe some shrink tubing type of stuff, etc. Not sure what.
That way I can cut the case down to less than half and keep the circuit board in it. Then have the coil hanging out of the case but covered in something. Any ideas as to what I can use?

I was thinking of using a black plastic divider like you get with some binders, two pieces cut to size of coil/circuit board and using electrical tape to seal the two together.
I'll have to wait for my cheap qi puck to arrive as I've only got the N4 Orb/Dock at the moment

If you buy an official Nexus wireless charger ( https://play.google.com/store/devices/details?id=nexus_wireless_charger&hl=en ), just figure out how to mount that in your car. That's what I'm going to do in my Jeep. The magnets in the charger are plenty strong enough to hold the phone over bumps.
Edit: You could probably just cut the ball in half at the end of a suction cup mount (the pivot point for where the suction cup arm connects to the phone cradle) and gorilla glue the charger to the now flat half ball.
In my Jeep I'm going for a more permanent solution of gluing the charger to a phone cradle mount/bracket that bolts into the jeep. It's too easy to reach into my Jeep and grab a windshield mount.

[MOD] Turn Google's crappy Wireless Charging Orb into a clean magnetic car charger

Hey everyone,
This is my first modification guide thingy so I hope it is ok and useful to some of you. I purchased an N5 off of Swappa recently that came with the N4 Wireless Charging Orb and the newer glass-topped N5 wireless charger. I assume the original owner was sick of how the orb performed (Google failed with the design of it) and bought the other charger. I was about to throw it away but started doing some research. Some other people have modified the orb, but the results are extremely ugly. I'll show you what I've done and how I'm incorporating this into my 1999 Jeep Cherokee Sport. I want the result to look like it was factory installed and without any external suction cup wireless charger with ugly ass arms that clamp around the phone. I want it to be completely invisible until I plop my phone on it.
After I took everything apart I was going to try and reuse the casing somehow, so that's why this image is covered with a different covering than the Nexus imprinted rubber on the top. I decided against reusing the casing because it looked ugly and I found a better way.
Step 1 - Remove the Nexus rubber to expose the screws
Peel back the Nexus rubber covering to reveal the screws. I ended up ripping the rubber so be careful if you plan to reuse it. Honestly, you probably won't be able to get it to sit right even if you do plan to reuse it. The screws will be at 12, 3, 6, and 9 oclock.
Step 2 - Remove the screws to take off the top and and get access to the PCB/Wireless Charging Coil
Some people say you can just unscrew the screws, but mine were glued in with locktite or something. I had to drill them out. I used an 1/8" bit. Be careful not to hit the board. I hit the board a little bit ( since you can't really see it with the top on still) but everything seems to work. From there just take off the top and remove the board. You'll have to remove the 2 other screws holding the L shaped metal thing to completely remove the unit.
Step 3 - Buy Neodymium magnets and add them to the coil
I purchased these magnets (http://www.amazon.com/gp/product/B001ANVAHI/). They were $7.79 for 100. Since this is going in a vehicle and there's going to be bumpiness, I ended up using 44 magnets around the outside of the coil (stacked 2 high, all the way around). They hold on to each other and the coil magnetically, but I'll probably throw some double sided sticky tape around the edges to make sure they don't go anywhere.
Step 4 - Find the area in your vehicle where you're going to mount it and make a vinyl template
In my Cherokee, there's an ashtray which I never use (I don't smoke). Some people take out the ashtray and put a switch panel there for external lighting and what not. I thought, that's the perfect spot for a wireless charger. I grabbed some green car vinyl my friend had laying around, and cut it to match the ash tray. In the image above I layed it over the top, but I will be removing the ash tray completely so it sits flush. I plastidipped the vinyl black to match the interior of my truck (as close as possible) and to add a little more grip.
Step 5 - Mount and wire the wireless charger/vinyl covering
This will be done this coming Tuesday, but the image above is a test. It charges perfectly and is a very strong hold. I do not see this going anywhere when I'm driving. I'll reply to this thread with pictures of the final product next week.

Nicely done! Love the added magnets
Not sure I'd destroy my $50 charger to do this...but now I'm thinking of picking one of those cheap $15 Qi China chargers to disect

You have the Nexus orb? And yours actually works? My phone would slide right off of that thing and I'd wake up with a dead phone. You really wouldn't damage the thing if you were careful. You might be able to unscrew the screws without using a drill.

Mine works great because I don't use a case, so the back of the rubbery orb sticks nicely to the back of my rubbery Nexus 5! with my old nexus 4, it didn't stick naked, but did stick after I put a wet application protector. I can imagine most cases not sticking and it sliding off though

Here's my final setup and finished product! Head to 3:00 mark for the wireless charger.

Charging pins oxidated

Hello,
i bought a used watch about half an year ago. Because of used item, i have no warranty papers.
(and i use custom rom etc so warranty would be a problem too)
From the first day charging was a bit pita, as many items which need to be recharged (Logitech anyone?*G)
But now it is getting on my wick. I am used to use my finger for a fast clean of contacts, but now that is often not enough.
Using universal electronic cleaner doesnt work, too. Next step would be "hard" cleaner (Kontaktchemie 600) or a rotating brush of metal on my dremel. But that is normally not "for eternity" - u have to do it again and again and some day in future u will need to replace the charging contacts. That is no problem at mices, where i can buy a defect one, just to change the lower cover. But i dont like the idea to ruin my watch.
Do you have any suggestions?
Or are the charging contacts "replacable" for a small amount of money? If i remember right the pins are on the mainboard. Ok, so i can open the watch to do a comfortable clean on the contacts, but i think it will not work for long.
So i need ideas how to fix that problem. i am already thinking to give a try with solder. if the contacts will connect with solder. Then the contact would be higher, and when solder ist oxidated i can scrub and scrub... up to the point i will need fresh solder, but i will not damage the contacts on main board.

Have you tried a different charger?
Sometimes the charger or the cable are the culprit

I tried that first, but with them being recessed, it did not do the job. That has been my contact cleaner method for 30 years, though. :good:

What is that crap? i never saw oxidated gold.
Mike

First off, I doubt the pins are solid gold, but most likely gold plated. In this case, I would think scraping off the contacts will only compound the situation. For oxidation to occur, the contacts would have to be made of aluminium, which I doubt is the material.
I might suggest a neutralizer of some sort. Perhaps a solution of baking powder and water. probably have to do it on a regular basis.

Ok...
Some minutes ago i opened the watch.
The charging pins were/are nearly craters. And no, in the times before i didnt scratch them hard. But when using my watchmaker lupe there were craters, and they were oxidated. In the time before i used something like an eraser (on my dremel), and - when not working so good - on dremel too a brush of brass. normally i use that to clean electric pins that i can change if necessary.
But today i used a needle. why?
when having opened the watch i saw that there are pins in the buttom cover, which hopefully can be replaced. The charging cradle is not connecting the mainboard on the direct way. The pins in buttom cover look very cheap, even when sold with much profit it should be not soooo expensive. IF sold. i will look for it.

Take a look at these folks. They seem to be the only ones selling parts that I have found.
https://www.maxbhi.com/search.html?...N&product_type_id=0&search_id=&q=huawei+watch

I had the same problem with my Huawei watch. I found on ebay the back cover at $ 45 at Shenzen Sueyue Trading Co. Ltd. I ordered it and it came in 20 days to Istanbul. Then it was very simple to exchage the back. Just make sure that you take out the speaker from the old cover and you stick it on the new cover with double sided stickers or some silicone glue. Mine is working fine now. You just have to make sure that the pins do not get oxydized again ( from your sweat, like in my case ) Good luck. By the way, this company is both on Ebay and on Aliexpress, but they don't sell this item on Aliexpress. If you talk to them, they can arrange to ship it to you via Aliexpress.

Well hello, I was dealing with the same problem... I found on ebay back covers, but they were pricy as hell, on my charging pins were craters... like, big craters... I think I may be using too fast charger or wth, because in dark when i connected my watch i could see little sparks between the back cover and the charger, maybe connecting the charger first to watch, and then to wall would solve the problem, but I didn't know that... So I soldered a little balls of solder on the pins and it works flawlessly ever since. The solder tends to oxidate, but it can be easily brushed off.
But the warranty is void... And last month my watch broke, so I had to order the back plate even tho the price is high and send it to the RMA after that.

The problem has nothing to do with the pins! Huawei in their stupidity and greed just used a super-dumb chip in the charger that can not negotiate with 'smart' chargers. Just plug the charger in a normal pc/mac usb and voila. Or dig up a dumb 500ma charger from your closet. Same thing with Trekz bluetooth headphones. Why would anyone save a couple of cents on a product that costs over $200 is beyond me. Idiots.

After 1 year pins in my HW1 look like new. Maybe because I never used supplied charger?

I had the same problem with my Huawei watch. I found on ebay the back cover at $ 45 at Shenzen Sueyue Trading Co. Ltd. I ordered it and it came in 20 days to Istanbul. Then it was very simple to exchage the back. Just make sure that you take out the speaker from the old cover and you stick it on the new cover with double sided stickers or some silicone glue. Mine is working fine now. You just have to make sure that the pins do not get oxydized again ( from your sweat, like in my case ) Good luck. By the way, this company is both on Ebay and on Aliexpress, but they don't sell this item on Aliexpress. If you talk to them, they can arrange to ship it to you via Aliexpress.

Sending order now, will update on arrival

same charging issue, different cause
Hi, I was having the same issue, eventually I looked very close in the pin area and I found some dirt that accumulated on its edge (see the picture). I used a toothpick to remove it and now the watch charges no problem. The dirt actually was preventing the pins from touching those on the charging cable, adding extra undesired thickness.
Hope this can help someone here in the future

I have the same issue.

I'm now having these problems, as everyone else one of my contact pads looks like it has a crater. In no way does this this have to do with the charger, I've been using the same one for 2 years with no problem until recently, connecting just got worse and worse, now it won't charge at all.
Last time I had a problem I cleaned them with rubbing alcohol and cotton swab, it gave me a couple months but it's not helping me now. So that maybe worth a try before going crazy with abrasives incase they get damaged more.

I had the same damaged charging pins. I bought replacement back for $12:

They are only showing the gold case available for me, none of the other parts unfortunately.

Back for W1 in black also seems to be available..
