From Raspbery Pi to PCB/Manufacturing? - Raspberry Pi Q&A, Help & Troubleshooting

So long story short I have made a concept product but I need to migrate it to a real prototype so I can get funding. The issue is I have never done this type a thing before. What is the next step?
Do I get a PCB board manufactured with the parts I need (ARM CPU, Micro-USB to connect to phone, and power input)?
Has any done this and have any tips? I don't know where to start.
THanks!

What part of the process are you on? You have a schematic? Do you have it hacked together in a breadboard or something?

I have it hacked together on a breadboard right now.

What you need to do is use something like eagle to put together a schematic and board layout and with that you can create the proper Gerber files to send to a board manufacturer. From my experience itead is a pretty reasonably priced option but they take forever to ship back.

[Q] Cameras disassembly

Hey guy's
I need to remove the fornt and back camers from the device because i'm working in facility which prohibited to enter with camers.
I would like to know if the device will continue to function WITHOUT the camera module?
I mean, if I remove the camera modules from the device, will it function normaly?
Thanks!
good luck
do they even see you've a front camera?
Why don't you get an old crappy phone to use there and your sgs outside ?
Because I need to use some of the features of the device while working
Any1 can please answer my question?
Just tell them you removed it....its not like they will break your phone
Sent from my GT-I9000M using XDA App
I doubt anyone here will know.. If you are good with electronics, check the way they are connected to the mainboard. But realistically, you can only try it. Not sure if both cameras would be connected to a separate board though
I've broken down PDAs and smart phones over the years and even done a lens replacement and a camera module replacement on an iPhone. I can tell you right now the time cost and angst are not nearly worth the effort. For example the back case replacement on the iPhone 3G requires an almost complete tear-down of the device minus thankfully separating the glass screen from the digitizer and the LCD. I do not do this repair in my business because the cost and time is worth more then the device its self.
That all said, you have a unique situation that possible requires unique effort. If your company bought the phone for you I would say go for it, with approval of course.
Odd you would need the device but not allowed cameras... you designing a competing device? You wouldn't work in Redmond would you?
Alright enough teasing. Disabling or removing the modules might mess with so many other components or even the OS. Think of it as simple PC with a missing component, sometimes it wont boot without it, even though it seems completely unrelated to the core system. Without being on the design build teem of said device, its a crap shoot it would even run without the modules.
Removing the lenses might be a better option, as silly as that sounds. Just taking one apart is opening a crazy can of worms. And I seriously wish you luck.
Call Samsung and tell them your Q from James Bond maybe they will offer to help. Seriously, try the manufacturer, after they say up and down and over and over again that it will void your warranty, they might just help you.
This site is more about software development, mods and roms, then actual hardware work. Good luck though! And post pictures of the break down... ahhh... with a different camera, ...and not at work. ;-)
Just place some tape over the lens. =)

Why don't you use some paint?
Then you don't need to ruin the phone.
They can test it and it will not show anything.

well I guess that you should just dissable it http://www.careace.net/2010/06/09/disassembly-of-the-samsung-galaxy-s/ and remove the lens and tape the wires ..
Can I ask you a question. Are you a spy? Just kidding lol. Looks like you'll have to give this one a go yourself. It's not like people take there cameras out there phones to see if they will boot everyday. If you find out the answer please report back...

Since paint would not be easy to remove, maybe your workplace would be ok with that? Would look ugly though.
Maybe buy a cheap phone for work and leave the SGS at home or in your car (if you drive).
You sparked my interest, ...I found a fairly good site with a break-down list with pictures and I think a video of the disassembly.
http://www.sprintdroids.com/forum/s...-galaxy-s-torn-down-extensively-detailed.html
Sorry about the jokes before, I just couldn't resist.
A hint on after tear downs, restart up procedures can be odd. The iPhone likes to be restarted up in recovery mode or it wont boot. And stay grounded! Use a grounding wrist strap. One static arc and it will fry any of the multitude of chips.
I have know idea about our Galaxy S's. Read study and Google it a lot. I did my best when I read about all the mistakes and failure people made, and there were many. Over time as this device becomes more popular it will have far more data on the web. Right now its so new not to many people are cracking the cases with being under warranties etc... Good luck and let us know how it goes.
Don
If you use right paint. Use waterbased paint.
You could easy removed it with car polish without damage the lens when you dont want it anymore.

Not forking over $30 for something that is physically unnecessary. It basically "opens up the ability" to do something the phone can already do.
Yeah, it IS completely unnecessary. I'm thinking that someone should be able to get it working for free soon.

Well I thought I'd give it a stab in the dark. I copied Dockprovider.apk, Dockservice.apk, and Portalapp.apk from Here over to my system/app folder and immediately got system force closes. Rebooted and set permissions in Root Explorer, reboot again.
The only menu available when putting the Bionic into my HD Station is bedside and productivity modes. I have to copy the OEM files back and fix permissions to regain full use of HD Station and HDMI cable.
I'll keep working at it and see if I can modify the files to work on the Bionic, but don't count on anything as this will be learn-as-I-go lol. I sent a message to Fenny who made the post for the Atrix Webtop hack...we'll see what happens.
I just watched a YouTube video of a guy that got the USB host on the Atrix to work outside of webtop using 5V on the power rail..... I would assume some sort of trigger mechanism should be possible with the Bionic and webtop.... I might get one of the $30 webtops and canabolize it to see if i can figure out what in the device triggers webtop. Would be an alternative to modifying the menu to always allow webtop.....
Actually, I wonder if you activate the usb host and plug in hdmi if that will trigger webtop.... I will mess with it this weekend...

Completely doable and done it with car dock and standard dock....
Don't know if you've already seen this elsewhere. But if you either own the car dock or the standard dock (I have both, thanks to Costco) there are 4 screws on the back of the car dock (covered by rubber grommets) remove these rubber grommets and remove the screws, VERY carefully and pull the back cover, and you'll be greeted with a tiny PCB with a cable going to the micro USB connector. The PCB is only clipped in place, so remove gently from the dock body. Slide out the micro USB, connect it to your DB's micro USB slot and connect the HDMI as well and to a display of your choice. As soon as you do so, you will be prompted to select a profile. You will notice the webtop option is now available. Select it.....
The same applies to the standard dock. Remove the rubber feet, unscrew, unscrew PCB and cable management clip....plug in and done.....
Or spend $30 and get yourself a webtop adapter.
Btw, Apple's magic mouse does not work with DB even though you can pair it.

[Q] Solder More Memory On Motherboard

Hey guys,
So I wanted to know if it is possible to replace and solder new memory on the G1's mother board (replace) ???
I love my G1 and all, but I just want it to be able to push a bit more...
If it is at all possible, I will get started on it right away and post my progress...
I'm open to all suggestions...except buying a new phone =P
good luck!
this will be amazing if you can do it!
i am holding a g1 motherboard in my hand and im not sure how you could,
or even if you did will it still work
i'll check back on your progress because i love the G1! i cant find a better looking
phone anywhere (my opinion) and if we could just add more speed and memory
this would be by far the best phone out there!
good luck!
It 's not like the old Comodore Vic 20 piggyback memory mod
Yeah, I dought it would be worth it. I use to work for a company that would populate surface mount boards back in the mid 90's. You need a fine point soldering iron just to solder something onto a board. You then need an IR or hot-air machine to remove a components with more than a few legs.
It takes a steady hand to work with the 'larger' surface mount components. Over the decades components gotten smaller and fine pitch has gotten finer(the number of legs per inch). Many components have gone BGA witch means that the legs don't even stick out, they are between the board and components. Many times reworking BGAs two different solders are used with two different melting points.

Why don't you follow one of the de-bricking guides? Unless he threw your phone hard against a wall, those guides should help you. Nevermind the memory soldering, but you'd have your G1 back...

Appreciate the help, but it's been "hard-bricked". No coming back from that unless it's with JTAG. And I really can't find any repair shops around my area that offer that kind of service =(
Apparently my friend messed up something with the root and went back to Android 1.0 and then flashed the wrong SPL.
Unless someone knows of a way other than JTAG or replacing the motherboard, I'm gonna have to get myself another phone.
I've been 'phoneless' for almost a week.. I hope no one on XDA goes through losing a beloved device and then not having a phone at all...
And I can't just go and grab me a nice phone either.. horrible finances at the moment (unfortunately)....

Loose Micro USB Connetor

I thought I got lucky and got a N7 without any problems but it looks like my micro USB port is defective! The plug only works if I lightly push it down, the contacts inside aren't connecting properly. I've attached a picture showing how I had to rig it to get it to charge.
Interesting. Mine has been on charge for 5 hours and it still won't switch on or give any charging notifications. I've already requested a refund from google, but if this works I'll at least be able to spend the £15 play credit on books!
when come out of the package, there is a clear tape/wrap around the plug, did you remove that? I didn't bother to remove mine and I find the usb plug to be pretty tight.. tighter than all other devices I've owned..
Odd, if anything my USB port/cable are tighter than any other device I own.

You're keeping it, in this state? RMA is your friend
This sucks! I need to be able to use this device daily for work. It's replaced an older one I've gotten rid of. Will Google send a new one first?
try replace a cable first?? Use one from your phone and see how's the fitment first. Could be just the cable.
I have noticed that the one that shipped works fine, but I have another one with a longer cord (so it can sit on my desk and charge it's a long way to the floor) and that one slips out unless it's sitting on the desk I can't use it or the plug will fall out.
Mine seems to be the tightest fit of any device yet but I have left the plastic on the tip.
If you have to rig it like that it more then likely has a bad solder joint meaning it the charging port needs to be re-soldered back down to the phone, or the port may need to be replaced because one or more of the legs has broken off of the back of the port, or one or more of the pins inside the front of the port is bent out of place.

Yes, ask for an Advanced RMA. Although, to get one you need to give them some payment information. They send you another device and put a hold on your credit card until they receive the other device.

My USB port has become loose after a week of general use and charging. Going to contact Google for repair / replacement I think. Not the first device I have had this problem on - although I doubt like my Alienware they will send an engineer out to fix it on site (now that is service).
Ive got this problem now too. GOing to return it tonight and hopefully get a new one.
Had to return mine also
I had to return my micro USB plug also ,,, but Nexus sent another
in about a week ... called them for info on how ,,, and they
sent info to email ..
I understand completely, I wish someone would tell me a simpler method than resoldering the port. I'm nowhere inclined to do this myself being as I have no clue how to even begin how to solder anything. I have to use 2 rubber bands, an 8 inch strip of clear duct tape, a bottle of hair gel to add weight, and my microwave to hold it all in place.. =| HELP??????!!!!!!!!!!!!!

Wi-Fi MAC Address: Unavailable

Hello,
the problem I've with this phone is that the wi-fi wont turn on, either the bluetooth.
So I tried different roms, stock 2.3.5, and then cm10.1.2 stable, and the same issue.
The last thing I tried was a simple one-click odin installation consisting in a super wipe plus the installation of a stock 2.3.5 firmware.
And here I am, facing the same problem. Actually when I go to "about phone", status, then I see:
Wi-Fi MAC Address: Unavailable
Bluetooth Address: Unavailable
At this point it seems like this is a hardware problem, and for that reason is more than welcome an oppinion in the opposite way

what if my captivate was shipped with a generic non-original battery cover and that's the thing provoking this issue? I'm saying this because battery covers shoud have some little metallic things on the back that improves the wifi, gps and bluetooth, am I right?

Actually, they should work whether you have the back on or off. I never saw that problem before you and the guy mentioned it in the 4 years I've had this phone. It's quite odd.

Also I found this:
near to the screw that is close to the sd card slot, there should be a copper pin coming out from a tiny hole. Every Captivate has that tiny pin of copper, that should match with a white spot in the back of the battery cover.
Mine doesn't have that tiny pin; there is nothing but a tiny hole in that spot.
So this is what happen when youg get a refurbished Captivate on eBay these days...

I don't think this pin is the problem. Unable to turn on <something> usually means the system did not recognize the module during boot process. As it was mentioned already, Wifi/Blutooth on Captivate works fine with back door removed. Missing part indicates the phone was disassembled and someone attempted to repair something.

I remember reading a thread a year or so ago about a guy who replaced that pin after having problem with his cappy. He had done it by himself though.
I might be wrong but what you suggest would come from the modem and/or kernel which seems to work fine on every other phone that runs CM.
It's a shot in the dark but it's what we got for now if you check what the other guy has tried so far (in the other thread with the same problem). Could be a good idea to ask that other guy if his phone still has the metal golden pin.

I'm not sure either, not very familiar with phone software specifics. I'm a computer guy and in computers missing software controls means device not initialized. Kernel/modem software is fine, but there is something wrong with the hardware. I personally don't believe restoring the pin will fix the issue. On a good Captivate, even with this connection open (back cover removed), wifi/bluetooth works fine. A good repair guy have to take a look here and check all currents/voltages from SoC through amplifiers to antenna. Shooting in the dark is asking for more trouble. On the other hand there is no point to pay for shipping/repairs on a $90 device.

Yes, I will! actually this thread had pointed out some interest, I'm saying this due to the over 200 visits it had in just a few days lol
Back to the topic, this phone definitely was disassembled because it was a refurbished unit bought from a big store on eBay.
This piece of.. hardware, cost me $89 by the way, and the only solution I got from the seller -as I'm overseas now and I can't ship it back without expending lots of money- was to get a refund for the half of the price...
So basically I got this $45 Captivate that only works for:
calls, sms, music, storage & camera
Still, I don't think that $45 is a good price of this piece of... hardware.
And yeah, now I'm convinced that the missing pin of copper it's not related to the wi-fi issue, actually that pins only exist to improve call reception as I was told by the seller.
Therefore, and after flashing many stock and non-stock roms through Odin & cwm respectively, I must conclude that this is a hardware issue.
So I'd like to know if any of you guys would drop me a link of a DIY for disassembling and replacing wi-fi hardware on a captivate, because I've another Captivate with a different issue: usb port broken, so I can take the good parts of both and create a fully working Captivate
let me know

BT/WIFI main logic in inside SoC, can't replace it. There are few external components you may check, but you need oscilloscope, good voltmeter, some special tools and advanced electronics repair knowledge. DIY repair in home conditions is not possible. I can send you the repair manual, if you want. One thing you can do is to repair the USB port on the other Captivate. It is doable, but you still need some equipment like vacuum pump, precise soldering gun, solder wick, good flux, etc.
