05:24 <brolin_empey> Joerg-Neo900: ?

06:24 <Joerg-Neo900> brolin_empey: sorry

06:25 <Joerg-Neo900> Oksana: what? power consumption of the SoC?

06:27 <Oksana> About, yes. just looking into the topic [since other power consumers are display, speakers, DAC/ADC, modem/wireless...]

06:34 <Joerg-Neo900> ~power

06:34 <Joerg-Neo900> hmm

09:49 <esbjerg> does anyone know if it will be possible to de-solder the microphone and perhaps the camera on the neo900?

09:50 <atk> everything is possible if you have the tools

09:51 <atk> it would be a shit phone without a microphone though

09:52 <esbjerg> I would use a headset

09:53 <atk> right

09:53 <esbjerg> it came during a discussion on a hacker festival

09:54 <esbjerg> quite a few there de-solder microphones etc.

09:54 <esbjerg> we also discussed whether it would be possible to have speakers which can only play sound

09:55 <atk> I don't think so

09:56 <atk> but you can make your audio circuitry not-overengineered enough so that it's impossible to use them as a microphone without hardware modification

09:56 <esbjerg> which would be very nice

10:30 <DocScrutinizer05> esbjerg: I think you missed a few elementary design details of GTA01/02/04 N900 and Neo900. I can't see any reason to desolder microphone except when the details of neo900.org/stuff/cccamp15/ccc2015talk/talk.pdf#19 to #21 are not understood at all

10:34 <DocScrutinizer05> same with camera: when you don't trust your own linux system you wrote, compiled and installed, then why would you want to use such system at all, let alone why bother about camera in such system?

10:36 <DocScrutinizer05> in Neo900 we follow the approach that allows user to 100% unspoofably tell if camera is powered or not, just in case you managed to actually install code you don't know what it does and it goes rogue and enables camera (or phone, or mic whatever) without your explicit consent. This gets done by LEDs you can't block shining when the subsystem is powered up

10:38 <DocScrutinizer05> when you want to strip down features you're afraid you can't control, why not use a featurephone right away?

10:46 <DocScrutinizer05> just to make more clear: we're using digital mics that have a data-out line and a Vcc supply voltage input which is controlled and can't get powered up without user noticing the fact

10:46 <DocScrutinizer05> without voltage supply the mics don't work

10:47 <DocScrutinizer05> same applies for camera, obviously

10:49 <DocScrutinizer05> and do you unsolder the beeper speaker of your linux PC? why not? with nifty software and crappy hardware it *could* get turned unto a microphone

10:51 <DocScrutinizer05> prolly you just trust your linux to not have such kernel drivers installed that would possibly accomplish that trick

10:53 <DocScrutinizer05> when you can't trust your own linux system to not do rogue stuff, you better don't use any such system at all. I wouldn't

11:07 <esbjerg> I don't think I will ever be able to control all hardware and software - even if I have access to all the code and produce all the hardware myself

11:09 <esbjerg> so I consider all electronics to be compromised in some fashion - and try to minimize the attack vectors which I find are the worst

11:29 <atk> DocScrutinizer05: unless the LEDs get burned out :P
