DocScrutinizer05Web-aptosid876_: 3.5" really? with composite? nah, I doubt that has much use for anything. Unless you want to run some smartphone UI on it00:35
DocScrutinizer05pocket computer? doesn't seem to really pan out00:36
DocScrutinizer05when you're after a pocket computer with 3.5" good display: used N90000:37
DocScrutinizer05seems you should be able to find one for same or lower cost than your DIY pocket thingie00:37
DocScrutinizer05heck, the display alone costs 45 bucks00:38
DocScrutinizer05or get an openpandora00:38
DocScrutinizer05240 bucks for the classic version00:44
DocScrutinizer05N900 should be half of that00:44
DocScrutinizer05but then the pandora has a 4.3" screen00:44
DocScrutinizer05btw "Resolution:480x240" for your aliexpress display! :-o00:47
DocScrutinizer05http://www.aliexpress.com/item/Free-Shipping-High-Resolution-5-800-480-Digital-Panel-Car/1703120298.html?s=p  way better bang for the buck00:53
DocScrutinizer05http://www.aliexpress.com/item/Free-Shipping-4-3-inch-Car-Rear-view-Monitor-TFT-Color-LCD-Monitor-DVD-VCR-with/1135361914.html cheaper00:57
Web-aptosid876_DocScrutinizer05: I've been spending hours looking thought the results on aliexpress but only the non-mirror ones. I plan to use it for a external camera display00:58
Web-aptosid876_I agree about a 480 display thats what I spent so long looking for00:58
Web-aptosid876_but the small ones are fakes where they list the correct res or there one or two that don't give a more tipical res, I expect there not 480 too.00:59
Web-aptosid876_I've wondered about 5" but I think it's getting a bit big compared to the size of my camera01:00
Web-aptosid876_it's a ultra compact cannon sx250hs01:00
DocScrutinizer05I don't het the exact usecase you plan for01:01
DocScrutinizer05a 480*240 doesn't seem fit for a viewfinder of a camera01:02
Web-aptosid876_I was thinking it could double up as a pockect computer display too for a test at least01:02
Web-aptosid876_my camera gives me 4:3 out01:02
Web-aptosid876_even when videoing01:02
DocScrutinizer05and for any "computer display" you definitely don't want to go for 240*x resolution01:02
Web-aptosid876_it's not preferable yes but then 320 is the same as my nano note :)01:03
Web-aptosid876_really i'd like a 4.*inch one01:03
Web-aptosid876_I don't maybe 5inch is the way to go arrr I go in cycles01:04
Web-aptosid876_I have gone in cycles about that pandora I decide not too. human input is a mess in the kernal = stuck to one kernal (now if only they had gone the way of eoma-*) also the usb host is broken. usb1 crashes it = nono for me (i'm getting the dam thing for usb host)01:06
DocScrutinizer05I don't get it. How do you plan to power such a monster? how to fix it to the camera?01:06
Web-aptosid876_some of the little lcds give voltage ranges of 9v min btw. but it would be with some small battery. maybe a tiny lead acid :p :| then only need 600ma01:08
DocScrutinizer05and what for you plan to use it with that camera?01:08
DocScrutinizer05all those car monitors seem to eat ~3W or more01:10
DocScrutinizer05unbearable for anything "pocket"01:10
Web-aptosid876_my camera is a fixed screen for taking pics but it also does good video 1080p @ 23.9**fps. but I'm annoyed when moving about that I can't always see the screen easily due to it being above me or waist height01:11
Web-aptosid876_but yes it concerns me01:11
Web-aptosid876_so I was think for something more serious I'd get a parallel rbg lcd that would hock up to my improv when ever I get it :)01:13
Web-aptosid876_long term I'd like to get a neo900 for a pockect computer with usb host and normal(no faulty) sound01:13
Web-aptosid876_but that won't be readily for this little event in May nor do I have the £££01:14
DocScrutinizer05yeah, that would make sense, though for a mere pocket computer it's way too expensive01:14
DocScrutinizer05the WWAN costs $$$01:15
Web-aptosid876_well a all in one pockect computer01:15
Web-aptosid876_+ phone. and better then the bloody phone is gps nav :)01:15
DocScrutinizer05yeah, I hope GPS will work fine, with glonass too :-)01:16
Web-aptosid876_any suggestions for a composite small screen :) ?01:17
DocScrutinizer05sorry, no idea01:17
Web-aptosid876_or keywords01:17
Web-aptosid876_to help me search01:17
DocScrutinizer05pocket TV?01:17
Web-aptosid876_what about diy? composite converters?01:18
Web-aptosid876_lcd 2 composite 01:19
DocScrutinizer05http://www.engadget.com/2014/04/11/auo-quad-hd-amoled/?ncid=rss_truncated&cps=gravity  ;-)01:24
Web-aptosid876_good to hear now to wait for them to filter down to the likes of us.01:27
Web-aptosid876_I think I'm better off saving £100 instead of getting a pockTV and putting it towards a camcorder 01:28
DocScrutinizer05well, sorry, seems I can't help much01:28
Web-aptosid876_I'd not done yet with you :D01:29
Web-aptosid876_but thanks for your efforts01:29
Web-aptosid876_ok so.... with the n900 . . . 01:29
DocScrutinizer05~100GBP, used01:30
DocScrutinizer05800*480, 3,9"01:30
Web-aptosid876_£45 I thought on evilbay01:31
DocScrutinizer05when it's not in mint condition01:31
Web-aptosid876_there a snag how to get one with out using evilbay01:31
wpwrakWeb-aptosid876_: btw, these guys have some nice displays and they're very "westerner-compatible": http://www.buydisplay.com/01:31
wpwrakWeb-aptosid876_: not a lot of size/ratio/resolution choices, but they're a good place to start looking for things01:32
Web-aptosid876_thanks wpwrak01:35
DocScrutinizer0525 bucks01:36
DocScrutinizer05AV aiui01:36
wpwrakthey have the larger displays just as panel or with various driver boards01:37
DocScrutinizer05InterfaceVideo(CVBS), VGA01:38
wpwrakso you can pick what you like01:38
Web-aptosid876_bonus points for a sunlight readable little displays :D theres pixel Qi 7inch but no smaller and hard to get them by the looks of things01:38
Web-aptosid876_btw whats the brightness of the nano note display? i'll have a look01:39
DocScrutinizer05>>Power adaptor should be 12V/1000mA in output,<< BWAHAHA01:39
Web-aptosid876_12V/1000mA for the display01:39
DocScrutinizer05WTF they did on that controller board?01:41
DocScrutinizer05monster PMIC with two coils01:41
whitequarkhmmm, 12W?01:42
whitequarksounds reasonable for a backlight01:42
whitequarkalthough... no, no it does not01:42
whitequarkmy notebook's backlight eats somewhere around 6W01:42
DocScrutinizer05http://wstaw.org/m/2014/04/18/plasma-desktopN17816.png   http://wstaw.org/m/2014/04/18/plasma-desktopp17816.png  I bet that gets hot ;-P01:45
Web-aptosid876_nano note lcd brightness 200 min typical 25001:46
DocScrutinizer05backlight rated 40mA01:46
DocScrutinizer05I have NFC what they do with 12W01:46
Web-aptosid876_I found the blacklight bright enough in direct sun 01:46
DocScrutinizer05shoukd be enough to unsolder chips from controller board01:47
Web-aptosid876_so those 5w@12v lcd will just be bright enough01:47
Web-aptosid876_unsolder chips urrg pain and time01:48
DocScrutinizer05>>It can be used in any embedded systems<< suuuuure01:51
Web-aptosid876_a anwser for small portable computer is the 7inch kde eoma-68 tablet which I'm also planing to buy when ever they have the £££££ to ramp into production01:51
Web-aptosid876_( http://makeplaylive.com )01:51
wpwrakthey tend do be a bit, erm, conservative, with their power supplies. note the little monochrome lcds with fpc for data and extra wires for the backlight.01:53
DocScrutinizer05backlight: 19.2V * 40mA01:54
Web-aptosid876_so with the n900 is fptf ready? doesn't the sound need some bloody non-free bits of doom? or is that only in the original firmware?01:54
Web-aptosid876_I guess I had better switch to #maemo for n900 questions01:55
DocScrutinizer05http://www.buydisplay.com/download/manual/ER-TFTV050-3_Datasheet.pdf  is nice but useless for power requirements01:58
Web-aptosid876_I thought fptf had a lot to do. it's just I'd need usb host working with usb audio interfaces02:03
DocScrutinizer05well, N900 is a bit... fsckedup with USB.  but there's http://maemo.org/packages/view/hostmode-gui/ which fscks N900 fsckup02:14
Web-aptosid876_sounds like doom. neo900 here  i wait :)02:16
DocScrutinizer05hmm, a lot of stuff already tested and just works with H-E-N02:18
DocScrutinizer05like: USB<->ethernet adapters, EEG scientific equipment, RTLSDR02:19
DocScrutinizer05and yes, I thimk audio cards work too02:19
DocScrutinizer05(sound) there are some blobs in PolypAudio that Nokia built to improve audio qualtiy of phonecalls, and to protext speakers even on high playback levels02:28
DocScrutinizer05and a lot of apps rely on some closed policy enforcer daemon which switches mixer settings etc for differing/changing scenarios02:29
DocScrutinizer05audio itself is free. I.E you perfectly can use ALSA and everything will work, except phonecalls and prolly BT headset which depends on PoukeAudio but not on any closed bits02:30
DocScrutinizer05(BT) like on any other linux system02:30
DocScrutinizer05peole are runnng gentoo on N90002:31
DocScrutinizer05and ebian02:31
DocScrutinizer05debian even02:31
DocScrutinizer05and dunno what else02:31
DocScrutinizer05otoh maemo fremantle runs on beagleboard for example02:32
DocScrutinizer05without any blobs, but of course also without phonecalls02:33
DocScrutinizer05I dunno which of the closed source *apps* do run on beagleboard and which don't02:33
DocScrutinizer05prolly stuff like maps (GPS hardware), camera (drivers firmware hardware), etc will obviously fail on e,g, beagleboard02:35
DocScrutinizer05contacs and callendar might work02:35
DocScrutinizer05if you insist in using the maemo callendar and contacts02:36
DocScrutinizer05skype most likely is too crippled to work on any other platform then the target platform it got developed for02:37
DocScrutinizer05VoIP is integrated in telepathy-sofiasip but also into dialer which is a Nokia blob02:38
DocScrutinizer05you're free to port e.g. twinklephone though, I strongly encourage everybody to do so ;-P02:38
DocScrutinizer05(I admit I'm a tad biased here...)02:39
DocScrutinizer05you shuld ask mrmoku about what went haywire when he tried to port twinklephone to GTA202:41
DocScrutinizer0502 even02:41
DocScrutinizer05I think some odds with some libs it uses02:41
DocScrutinizer05libccrtpcpp or dunno what02:42
DocScrutinizer05or maybe libboost X-P02:42
DocScrutinizer05libboost would be easy to kick out though, just used for regex which isn't even mandatory for function of twinkle02:43
DocScrutinizer05(it's me to blame for the functions that need regex being in twinkle anyway)02:44
DocScrutinizer05sure, smart features, but not exactly vital02:45
Web-aptosid876_thanks I'll read the rest tomorrow. I right now I need sleep02:45
Web-aptosid876_I've looked at n8*002:45
Web-aptosid876_n810 is doomed audio wise02:46
DocScrutinizer05yeah, I almost was about to suggest "get a N810"02:46
DocScrutinizer05huh? how's it doomed audio?02:46
Web-aptosid876_debian would do if enough of it works02:46
DocScrutinizer05I actually love the N810 audio02:47
DocScrutinizer05I ofen use it as web radio02:47
DocScrutinizer05works great02:47
DocScrutinizer05I also often use it as mp3-player for my home stereo, via AV cable02:48

Web-aptosid876_DocScrutinizer05: re yesterday theres the tvstick I was wondering about http://www.aliexpress.com/item/New-MK808C-AV-Port-Out-AV-Cable-Bluetooth-updated-MK808-Android-4-2-TV-Stick-RK3066/1379381060.html17:53
DocScrutinizer05Web-aptosid876_: and you wanna do what exactly with that?18:18
Web-aptosid876_DocScrutinizer05: diy pocket-ish computer hehe19:53
Web-aptosid876_note the composite video out20:12
Web-aptosid876_I had used the wrong name yesterday20:16
DocScrutinizer05I understood you were referring to CVBS20:18
DocScrutinizer05>>8GB HDD<< :-P20:19
Web-aptosid876_? no I had said mk802c yesterday20:25
DocScrutinizer05hmm? on http://www.aliexpress.com/item/New-MK808C-AV-Port-Out-AV-Cable-Bluetooth-updated-MK808-Android-4-2-TV-Stick-RK3066/1379381060.html it says >>8GB HDD<< I guess they mean SD/MMC20:36
DocScrutinizer05or generally flash storage20:36
Web-aptosid876_oh I understand now20:45
DocScrutinizer05unionfs infos/knowhow anybody? Seems on my x86 linux (rpm) the only unionfs *available* is unionfs-fuse, aufs and unionfs (kernel based) don't even _exist_ ?21:48
DocScrutinizer05and installing unionfs-fuse doesn't result in any manpage becomming available21:49
wpwraktrying to make a DVD "writeable" ?23:11
DocScrutinizer05no, just trying to stay up to date re UNIX/linux23:16
DocScrutinizer05and today I learned that openpandora is using a unionfs, so I thought I wanna read the manpage, found none, frowned, checked what's available... http://software.opensuse.org/search?utf8=%E2%9C%93&q=union23:17
DocScrutinizer05pandora using aufs23:17
DocScrutinizer05google doesn't really help to figure what the heck is *fresh* info and what's dusty or even obsolete23:19
DocScrutinizer05I can't come up with a story why neither unionfs nor aufs seems to be available on suse23:20
DocScrutinizer05I'm rather sure e.g. knoppix offers some sort of unionfs to make the DVD "writable"23:21
DocScrutinizer05wonder which one23:21
wpwrak(old info) yeah, if you search long enough, you'll eventually find IFS. that's as old as it gets, at last on linux. of course, it's merely part of the linux fossil record now, long exinct23:21
DocScrutinizer05google doesn't answer "why there's no aufs on suse?"23:22
DocScrutinizer05and I'm just wondering why unionfs-fuse seems to come without manpage23:22
DocScrutinizer05or if it does at all, or I just missed a small detail23:23
wpwraknot everybody likes writing man pages. and sometimes, nobody else does it for them either23:23
DocScrutinizer05nevertheless I need to read the zypper manpage23:23
wpwrakof course, once you figured out how to use it, you can contribute a man page :)23:23
DocScrutinizer05to list files in unionfs-fuse.rpm23:24
DocScrutinizer05meh, gonna use yast23:24
DocScrutinizer05wtf?! http://privatepaste.com/a3e0a1bb6223:26
DocScrutinizer05what been the damn command to update the mandb?23:27
DocScrutinizer05and why the HECK didn't the .rpm postinstall do that?23:27
wpwrakthe more questions you encounter, the more opportunity to learn you create. it seems that you'll make great progress on the path to enlightenment these days ;-)23:30
DocScrutinizer05yeah, but honestly now, what's the mandb update command?23:31
wpwrakhttp://manpages.ubuntu.com/manpages/dapper/man8/mandb.8.html ?23:32
DocScrutinizer05nm, mandb it seems ;-P23:32
wpwrakin the old days, man would look directly for the file. i mean, the unix file system is a potent enough database in itself. dunno if man has somehow lost that ability now23:33
wpwrakif you just want to read the critter, try   zcat FILE | groff -Tascii -man | less23:34
DocScrutinizer05meh, mandb -f /usr/share/man/man8/unionfs-fuse.8.gz  did the job23:36
DocScrutinizer05so much for unionfs-fuse(8)23:37
DocScrutinizer05now, why the heck there's no aufs for suse?23:37
DocScrutinizer05nor a kernel based unionfs, which I bet I seen in old days23:37
DocScrutinizer05obsoleted by fuse?23:38
DocScrutinizer05wow, that's not even a real word23:39
DocScrutinizer05you're on buntkuh? what's your `apropos union` results for filesystems?23:40
DocScrutinizer05sorry, man -k union23:41
DocScrutinizer05>> If the user tries to modify a file on a lower level read-only branch the file is copied to to a higher level read-write branch if the copy-on-write (cow)  mode was enabled.<< might introduce some funny effects23:44
