Re: Crackly Calls and Battery Tips! A5/A6 rework. Corrected URL
You can find out the version you have via software query. otherwise take the front faceplate off and see the PCB rev printed there. There are roughly 3K V5 in the feild all built early on.. in june/july I believe, so the datecode can also give you a clue. There is no rework for a5-a6. the differences are listed in the wiki and I'm fairly confident that a large portion of the a5 were reworked, covered this a long time ago.. anyways, both a5/a6 can be reworked to improve the buzz issue some people have.

Re: Crackly Calls and Battery Tips! A5/A6 rework. Corrected URL
The A5 to A6 rework was handled at the factory for the most part. see http://wiki.openmoko.org/wiki/GTA02_revisions for details. WRT the a5/a6 rework, I've got to get back with Joerg and Tony Tu to finalize the SOP and then put in place a testing method. One problem is that the Buzz can be location specific. For example, when the Buzz first became apparently Sean flew out to me in SF with a sample of phone that buzzed. Mine didnt. ( he was on other travel ) Anyways, we turned on his phone--no buzz. Now imagine if you have a buzz and send it to person X to fix it. As part of the testing person X would operate the phone and verify that it buzzed. Well, what if it doesnt? does he apply the fix? If it does buzz applying the fix is a straightforward decision. On completion of the fix the phone is tested again and then returned. Does it still buzz after it's returned? So, here is where I stand. my todo list. 1. finalize the SOP and testing protocal. 2. recruit individuals and organizations to do the field rework. 3. Procure parts required for the fix. These parts will be given away either through distys or direct to people willing to do fixes. 4. Finalize rewards program. I'm not likely to get to any of this done before CES which is jan 8-11. It's not a matter of me taking time off for Xmas, but rather the Everest of other tasks and priorities. Experienced sherpas apply within.

Re: Answer from Joerg (was: Re: Crackly Calls and Battery Tips! A5/A6 rework. Corrected URL)
I did the big-c buzzing rework myself, with the precious help of a much more smd-experienced colleague. It was very difficult to replace the resistor because of the proximity of the components around the mic. A very sharp soldering iron is critical. I used a 1k resistor (didn't have a 2k2 of the same size at hand), and a 100uF/10V tantalum capacitor. So far, so good! The buzz seems to be gone for good. :) One caller has reported that I sounded like at the bottom of a pit, but this can be the other older issue...

I know of the cap on the uSD pins fix for the GPS vs uSD issue (though not the identity of that capacitor), I don't know what change allows a V6 to run without battery or if other differences exist. Dropping a cap on the two pins of the uSD socket is pretty trivial if you're already doing SMD work, so if we're already performing the Big-C rework I'd guess (pure personal speculation) that we could add the cap to the SD lines for little more expense and time. j On Thu, Dec 11, 2008 at 7:44 PM, Joel Newkirk freerun...@newkirk.us wrote: I'm going to talk to the guys at work tomorrow and show them the rework PDF - we are equipped to make this fix, could probably offer it inexpensively to those nearby (southeastern North Carolina) or those willing to ship.

Re: Crackly Calls and Battery Tips! A5/A6 rework. Corrected URL
Quick question for Steve/Jeorg: Would a 3528 package capacitor fit? And if so, would Tantalum be suitable instead of Ceramic? My guy here says he'd chose tantalum for filter use like this, and the cost difference is dramatic, though the size is larger than the ceramic shown in the pdf. (price diff: Ceramic around $2 each qty 100, tantalum around $0.25 each qty 100) The resistors are $0.02 each qty 100, so they're practically free. Ceramic: http://mouser.com/Search/ProductDetail.aspx?qs=t7T%252bw6J1MVWG%252bwA9gt9uDg%3d%3d Tantalum: http://mouser.com/Search/ProductDetail.aspx?qs=N31o%252bt096gsr1Po3ON6skg%3d%3d j On Thu, 11 Dec 2008 22:44:30 -0500, Joel Newkirk freerun...@newkirk.us wrote: I'm going to talk to the guys at work tomorrow and show them the rework PDF - we are equipped to make this fix, could probably offer it inexpensively to those nearby (southeastern North Carolina) or those willing to ship.
