Anyone interested? Here's mine! http://t.co/xb9ZyB36 ( 175915985738543104@rejon - 47s ago via Ping.fm ) 2012-03-03 12:11 whoa, fast! 2012-03-03 12:12 mh 2012-03-03 12:12 I've troubles in my PC. Awaking from suspend, the sound does not work anymore if there was any program with the sound card opened 2012-03-03 12:13 there should be a trick for that, but I don't know 2012-03-03 12:13 IIRC that's a known problem with ALSA 2012-03-03 12:14 but some people have some scripts that solve that, no? 2012-03-03 12:14 called at suspend time and awake time 2012-03-03 12:15 maybe the alsa-lib version would improve something? 2012-03-03 12:17 I'm using alsa 1.0.23... 2012-03-03 12:20 doubt it 2012-03-03 12:57 Jon Phillips: @sharism the workshop went quite well! Great attendance, most people interested in @milkymistvj + @qihardware + HTML5 :) buy a mm1 anyone?

2012-03-03 14:50 card gets config'd on snd_pcm_open() done in app 2012-03-03 14:51 I guess there is no easy or feasible at all way to suspend a PCM stream 2012-03-03 14:53 it works with OSS4 2012-03-03 14:54 well, probably as there's nobody taking care to change audiocard's initial setup to something app / pcm-stream specific 2012-03-03 14:55 anyway the concept of suspend is inherently wrong for mobile handheld 2012-03-03 14:56 simply because there's only one system-global suspend 2012-03-03 14:57 while on embedded mobile you want to "suspend" even sub-blocks of the CPU as soon and often and long as possible 2012-03-03 14:59 that's why you got dozens of power domains and hundreds of clock gates on contemporary SoC 2012-03-03 14:59 and static registers al over the place 2012-03-03 15:00 Linux has a run-time suspend feature, which suspends the unused stuff 2012-03-03 15:14 heh, what a clever chip 2012-03-03 15:14 http://www.datasheetarchive.com/dl/Datasheets-32/DSA-638286.pdf 2012-03-03 15:17 anyone using an encrypted rootfs in the nanonote? 2012-03-03 15:18 DocScrutinizer: static registers? 2012-03-03 15:28 there are enough paranoids here to have an encrypted nanonote 2012-03-03 15:34 i will be happy with ecryptfs support for the memory card :) 2012-03-03 15:37 woakas has joined #qi-hardware 2012-03-03 15:39 ah then you don't use it 2012-03-03 15:40 i use it on my others computers, not on nanonote right 2012-03-03 15:40 s/on/in 2012-03-03 15:40 kristianpaul meant: "i use it in my others computers, not in naninote right" 2012-03-03 15:42 bbl 2012-03-03 16:04 emeb has joined #qi-hardware 2012-03-03 16:08 acenovril has joined #qi-hardware 2012-03-03 16:19 Ayla_ has joined #qi-hardware 2012-03-03 16:48 GNUtoo has joined #qi-hardware 2012-03-03 17:10 hi, is it possible to get SPI on the SIE, the specs don't list SPI 2012-03-03 17:20 hi GNUtoo 2012-03-03 17:20 you mean SIE board? 2012-03-03 17:20 s/mean/for the 2012-03-03 17:20 kristianpaul meant: "you for the SIE board?" 2012-03-03 17:21 yes you can get GNUtoo SPI actually ADC is driven by SPI if i remenber right 2012-03-03 17:25 yes 2012-03-03 17:26 ok 2012-03-03 17:29 you own a SIE board btw? 2012-03-03 17:29 no 2012-03-03 17:29 because i guess SIE FAQ if existed you said is not produced anymore :) 2012-03-03 17:29 ah ouch 2012-03-03 17:29 So if you want get it to FPGA world, well.. get a M1 :) 2012-03-03 17:30 or what what your idea with SIE? 2012-03-03 17:30 it's only to flash SPI 2012-03-03 17:30 oops 2012-03-03 17:30 I meant 2012-03-03 17:30 we're looking for cheap boards to make flasher of BIOS chips with it 2012-03-03 17:30 like for flashing coreboot 2012-03-03 17:30 oh, no matter copyleft hw then.. so may be you need a buspirate? 2012-03-03 17:30 I've already a board that does that but it's way too expensive 2012-03-03 17:31 buspirate is very very slow but supported 2012-03-03 17:31 may be a small fpga plus usb.. what about an avnet spartan3 board for 50usd? 2012-03-03 17:32 flashrom requires SPI + GNU/Linux or a custom firmware on the target flasher that would communicate with flashrom on GNU/Linux 2012-03-03 17:32 yes is posible 2012-03-03 17:44 B_Lizzard has joined #qi-hardware 2012-03-03 17:55 qwebirc32410 has joined #qi-hardware 2012-03-03 17:55 ck rjeffries 2012-03-03 17:57 wolfgang woldspraul like you I find computational photography to be a very interesting new-ish area. e.g. Lytro 2012-03-03 17:58 in cas eyou did not see this short article here is URL: 2012-03-03 17:58 http://news.cnet.com/8301-17938_105-57388010-1/how-lytro-can-save-cameras/ 2012-03-03 18:00 wolfgang solfspraul here is another arguably "better" URL: 2012-03-03 18:00 http://www.extremetech.com/extreme/120571-lytro-why-it-might-succeed-in-spite-of-the-lackluster-camera 2012-03-03 18:01 wolfgang wolfspraul and for an eye opening similar but very different bit of computational photography Google this: Pelican Imaging 2012-03-03 18:16 antgreen has joined #qi-hardware 2012-03-03 18:17 rjeffries: note the date :) http://lists.en.qi-hardware.com/pipermail/discussion/2012-March/009485.html 2012-03-03 18:41 kilae has joined #qi-hardware 2012-03-03 18:54 Ayla has joined #qi-hardware 2012-03-03 19:23 qwebirc1340 has joined #qi-hardware 2012-03-03 19:23 wpwrak yes I was responding to that not eon the mail lit by wolfspraul 2012-03-03 19:24 s/not/snote 2012-03-03 19:24 rjeffries meant: "wpwrak yes I was responding to that snote eon the mail lit by wolfspraul" 2012-03-03 19:24 s/snote/note 2012-03-03 19:24 rjeffries meant: "wpwrak yes I was responding to that note eon the mail lit by wolfspraul" 2012-03-03 19:25 no I do not have $400 to spare to ship one to China. But this indeed is an interesting fertile field 2012-03-03 19:30 yeah. it's about time camera technology goes beyond those ancient concepts. it's kinda obvious once you hit a difficult scene where you realize that there's enough information to make a decent image. so why does the technology not allow it. 2012-03-03 19:48 urandom__ has joined #qi-hardware 2012-03-03 19:48 jekhor has joined #qi-hardware 2012-03-03 21:04 DocScrutinizer: you here? 2012-03-03 21:04 a question about the yesterday circuit 2012-03-03 21:04 what should I do with AGND of the modules? 2012-03-03 21:05 err, it is marked AGND on the pinout, but is actually connected directly to the common ground plane underneath the module pcb. 2012-03-03 21:05 so, probably nothing... 2012-03-03 21:13 indeed, I'm here 2012-03-03 21:14 you should NOT connect the two GND levels of the modules 2012-03-03 21:15 or connect them with 4mm^2 wire 2012-03-03 21:16 well, I have a pretty wide ground polygon running over my breadboard 2012-03-03 21:16 and I took the thickest wire I had to connect the modules to GND 2012-03-03 21:17 oh, I might have passed the UART through optocouplers. :/ okay, this variant of the design will be GND-coupled. 2012-03-03 21:18 another thought 2012-03-03 21:18 I only have one power source (batteries) 2012-03-03 21:18 the GNDs would be connected anyway 2012-03-03 21:18 the classic recommendation regarding GND in analog is: get a *star* topology, with center next to most sensitive input of the circuit 2012-03-03 21:18 by all means avoid GND loops 2012-03-03 21:21 hm 2012-03-03 21:23 DocScrutinizer: my (novice) "attempt" at "laying it out" http://imgur.com/sEqoS 2012-03-03 21:23 where did I manage to screw it up? 2012-03-03 21:28 the bottom half is almost finished (it's finished in the sense of power/gnd connections) 2012-03-03 21:28 the upper will be exactly the same 2012-03-03 21:30 its MTS simcard? 2012-03-03 21:30 yep 2012-03-03 21:32 wonder where on our superfamous radio market you found gsm modules 2012-03-03 21:32 * rz2k thought that that place is dead 2012-03-03 21:38 umm, well if that's 2 GSM modules, then where is the heatsink? 2012-03-03 21:40 btw I don't see any layput on that component side shot 2012-03-03 21:41 layout* 2012-03-03 21:43 * DocScrutinizer wonders what nasty kind of spy equipment this device will become when it's finally working. Call relay? 2012-03-03 21:43 bomb trigger? with hot standby/redundancy design? 2012-03-03 21:44 urandom__ has joined #qi-hardware 2012-03-03 21:48 probably some security system 2012-03-03 21:48 * rz2k already forgot what whitequark said to him about that thing 2012-03-03 21:57 re heatsink: you'd get away with this if you'd define it only registers and sends / rcvs SMS. But you asked for hooking up voice audio, which makes me ask "where do you dissipate the heat of the TX power stage?" 2012-03-03 22:17 DocScrutinizer: well, that's a why I called it "layout". it's a solderful breadboard, and the wires you see are almost all on the board (there's one wire underneath it which connects the VDD of the bottom module) 2012-03-03 22:17 (spy equipment) call relay. 2012-03-03 22:17 for civilian use, that is... no, seriously. its usage may be immoral, but definitely not unlawful 2012-03-03 22:18 (bomb trigger with redundancy) rofl 2012-03-03 22:20 rz2k: nowhere. I bought it in http://gsm-gate.ru 2012-03-03 22:20 whitequark: you ever looked into the opportunities of extremely directional high-gain GSM antennae, paired with GSM ME that knows to do register to a particular BTS only? 2012-03-03 22:21 mhm. actually not. this opens up some opportunies, but I don't quite get its relation with my circuit 2012-03-03 22:22 Nokia 6210 is such a device, it allows - in monitor/engineering mode - to set CID to SIM phone storage #33 (IIRC) and then registers *only* to that BTS 2012-03-03 22:23 while intelligent BTS *could* still tell distance to ME by TA value, they usually don't 2012-03-03 22:23 (heatsink) oh, I did not know they would be so hot. then I'll probably get unconductive thermal paste and attach the heatsiks on the bottoms of the modules (exposed). they're mounted to the pcb with hot glue 2012-03-03 22:23 read the application notes and DS of your module, it has advice re heatsink 2012-03-03 22:23 oh, you sure don't understand _why_ do I need that device:) the reason is actually somewhat stupid. er, I'd rather tell in PM 2012-03-03 22:25 if it's related to billing/plans, I'm not really interested - I know all the potetial usecases ;-D 2012-03-03 22:25 nope 2012-03-03 22:25 no you got me hooked 2012-03-03 22:25 now* 2012-03-03 22:30 i guess it's for those critical minutes between calling in the bomb threat and leaving the city :)
