Re: WIKI is in read-only mode?
Hi Radek and everybody, But one day your GTA02 will stop working - it might fall on the floor or whatever. GTA04 is only replacement - that's why it's important to support GTA04 - either by donation or buying the device. how it connected with the subject? This is not a reason to move the wiki or close it. This is an open source project, the marketing stereotypes (that the new generation hardware is the better replacement for old one) just not applicable. Just because that targeted to stimulate consumer market for sales, but not to give ability to people to create whatever they want. The potential of the hardware is not equal to the formal functionality of device. I plan to use the GTA02 as a core for robotic system, for example. Someone else maybe create something else with it (whatever it could be). It's logical to keep all data in one well know habitual knowledge base. And it's logical to keep it open for new supplements. Maybe i am wrong but openmoko as company is for years dead and nobody of the old admins is willing to spend much time on maintaining the infrastructure. I guess the number of spammers is now 1000x higher the number of contributors, that's why it's readonly. And it's no wonder that GTA04 has separate wiki because of these reasons. I'm as a user of wiki just don't care whether it contains some spam or not. I have a will to clean it if I found it, or doesn't if I'm lazy (or whatever). This is totally not a point. Honestly I don't understand the reason to close the access for users (who are main audience of the recourse) just to avoid the spam. It's ridiculous.

WIKI is in read-only mode?
Hi list, I just found that I'm not able to write to wiki today. And I see that some time ago there was discussion regarding of possibility to switch it to read-only mode or even move somewhere else. IMHO this is a wrong idea. Wiki is an open platform by its nature. So the volume of spam -- is just a result of that 1. visitors don't clean the spam when they found it 2. there is no capcha or any relevant mechanism to prevent robo-spam posting And another theme I was alerted by: this is a splitting of wiki for GTA02 and GTA04. I honestly don't really like that idea not even because I still use GTA02 and have no plans to reject it just because more powerful device is on the market, but also because a I'm not really love idea of buying new gadget just because it has more powerful processor. I love idea of keeping old hardware living for maximum long time, for reusing it and for improvement of functionality in the frames of given power. And I believe that a lot of people support my point of view. So, please don't archive old wiki and don't make it read-only. This is wrong way IMHO. And the main question. How to get access to the wiki eventually? thank you in advance, Dmitry ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: GTA02 power death
BTW, the bass rework looks very similar to what i was doing, i wonder who did that :) too bad it looks like i didn't warn everyone strong enough (though i did put a big fat warning on the rework page) when i discovered the shield must be additionally insulated after the rework, i apologise for that :/ heh, that thing flicked in my head when I solder capacitors, but I just give it up and limit the protection with tiny piece of sticky tape. Which is obviously was not enough :) Can you share the technique you used to desolder it? with hot air soldering station. but actually I fount that temperature is not enough (and I was a bit afraid to overheat PCF50633). So eventually I pick it out with the pincer helping myself with classic soldering iron. this is result of procedure http://www.shalnoff.com/pics/freerunner_desoldered_inductor.JPG Taking a closer look at the schematics and the PCF50633 datasheet i see that this inductor is part of the main step-up/step-down auto converter with an output current as big as 1.1A. It works at 1.7MHz frequency (the irc log i found appears to be unrelated). As far as i can tell that's unrelated to the self-resonance frequency of the inductor (that's always much higher for the modern parts). I'd get the one with1.1A rated current, and on 1.7MHz all of those having self-resonant frequency of 50MHz should work decently. I do not understand much in EE though so probably you'll want some quick advice from those who really knows inductive step-up/down converters. aha... everything is clear. I'll try one and report the result. I never removed LCD too, and everything was fine. It's shielded from the heat by the PCB itself, and i doubt you could have heated it up too much. it gives the hope :) will see. Best of luck! thank you again! have a nice weekend and happy Xmass! ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

GTA02 power death
Hi everybody, The situation: I've use for a couple of month this battery http://www.ebay.co.uk/itm/Battery-Cell-Fit-RoHS-Garmin-GPS-Mobile-10-GPS-Mobile-10x-GPS10-/300575864789?pt=UK_In_Car_Technologyhash=item45fbb7b7d5 yesterday my device accidently start switching off (after night recharging) and make some strange buzzing on power on without any visible activity (screen was kept black). So I decide that is a known complete battery drain problem and try to animate the device with external power. However, after several attempts I've got it booted. The screen picture was surprisingly inverted (!) but after sleep and awaking procedure it gets normal. After that, I've got idea to measure the battery voltage and found that it is 4.1 v (instead normal 3.7). Eventually I deside to leave it as is and try to find the cause at morning. I switch it off and go to sleep. Today I repeat operation with all similar symptomes (noise on power on without any other reactions) but without any success. Contrariwise, after several iterations of unsuccessful tries, when I power it on with battery and original USB adapter, it suddenly turned on for the second, then screen start gets brigther and finally I feel sweet smell of burning isolation :) I immediately remove all power sources, disassemble the device and found that I've burned some tiny IC near the PCF50633HN. The question: I digg all internets regarding the PCB layout but can't find anything relevant (there is no PCB layout on the wiki?). I suppose that was RT9013 (at least that only component in this schematic block that has similar package) but I'm not sure. Could anybody help me to identify this component? here is HiRes picture of the patient http://www.shalnoff.com/pics/freerunner_pcb.JPG You easily find it by burning fume around it :) except of that would be intereting to get some hints what the real reason cause this situation. And why LiPo battery can start to show 4.1v? I suppose that has some connection to the charging procedure (I use QTmoko without the non-original battery patch). Thank you for any hints in advance!

general SD card read/write problem

The board wouldn't fit into the case anymore, that understandable reason, but ... I see simple compromise, which is, to my mind, quite suitable for device audience and relevant to the spirit of the project... this is not a big difference with 2.5 and 3.5 socket pads. why not make just a bit wider pads under the socket to give a possibility to solder other jack for the people who would like to do that and ready to drill case hole to make it wider. If I don't mistake ther is enough space over the socket in the case and even if not, the case easly can be modified by little filing. at least (even if it stay in current status), what would be good to take into account this is the order of pins in the socket. Current GTA02 jack have non standard punout where is a 3 contacts jack just short one channel and to get normal stereo you need to get 4 contact jack and 3 pins socket and resolder it by youself (that what I did, for example) this adapter (which has similar order of contacts on the both sides) didn't work http://www.dealextreme.com/p/2-5mm-male-to-3-5mm-female-adapter-cable-white-14-5cm-23191 so you would have need for a new one too...
