#qi-hardware IRC log for Wednesday, 2015-02-18

wpwraksome people have a peculiar sense of humor: www.screwschina.com (and yes, they make screws and are located in china, but ...)03:27
eintopfwpwrak: but what? You wouldn't use screws from china?09:40
eintopfI mean a screw is screw09:40
eintopfs/is/is a/09:40
larscjust make sure you don't get screwed09:46
eintopflarsc: ah, I think, I understand.10:36
wpwrakeintopf: i was just looking for information on small screws. the sort i'll have to put into anelok to make the case a bit more robust12:44
wpwraklessons learned: you can google all you want for "torx t5 screw" or such, the best you'll find are fiendishly overpriced cell phone replacement screws (something like USD 2 apiece)12:46
wpwrakwhat you really want to look for is called "self-tapping" screws. and of these, it's the "thread-forming" kind (and not "thread-cutting", although some make take the terminology loosely)12:47
wpwrakand the size won't be given in the size of the opening (T5 or such) but in the diameter of the thread, i.e., M1, M1.6, and so on.12:48
wpwrakthe small cell phone type screws still seem elusive - western sites seem to prefer large sizes. M3 and bigger.12:50
wpwrakbut at least i have been able to gather enough information to know what i'll have to do to make such critters fit. turns out that it's not too bad. i need for M1.6 are few slots in the PCB that are at least 2 mm wide and 2.2 mm deep.12:51
eintopfi know these smartphone screws, I bought some tool set from china13:07
eintopfwith plastic pieces which looks like a plectrum from guitar13:07
eintopfand the small torx scredrivers13:07
eintopfwpwrak: you should not but some gamebody screws. These screws with some triangle hole. I hate these screws13:11
wpwraki've heard apple also have some fun ones: a little smaller than T1, so a T1 piece won't fit :)13:12
eintopfmy brother knows how to deal with such screws, you need a hammer and a four edged screwdriver. Than attach the screwdriver and hammer on it.13:14
eintopfbut you could also drill it13:14
eintopfanyway, I would not do the hammer method on electrical devices13:15
eintopffor cars, okay... that might works13:15
wpwraki think i'll not add compatibility with the drill and hammer method to the design specs of anelok :)13:16
eintopfsimple: use a normal screw without buying the special wpwrak repair tool set13:21
eintopfthats what they company try to do with that13:21
eintopfs/they company/the companies/13:21
wpwraknaw, torx isn't all that special :)13:25
wpwraksmall phillips would be an option too, though. torx is better but since the forces in use there are relatively small, phillips should do13:26
eintopfI have this set: http://src.discounto.de/pics/product/26850/43719_WORKZONE-Feinmechaniker-Satz-26850_xxl.jpeg13:36
eintopfand torx is included13:36
eintopfwpwrak: but you want a case for anelok? You said for me some time ago, that when you using a case you need to get some certificates13:38
eintopffor selling13:38
wpwrak(WORKZONE) they you're prepared for whatever the future may bring :)13:40
wpwrakcases can complicate things, yes, since they make it less credible that what you're selling is a "kit"13:41
wpwrakbut there's no much of a choice - you can't sell a bare pcb to end users13:42
eintopf(WORKZONE) the cheapest thing 4 ever. It's from ALDI. In austria it's "hofher"13:43
wpwrakfor the "alpha" units (small quantity, quite kit-like) we're probably fine without certs and such13:43
wpwrak(workzone) yeah, and nobody even specifies what's inside it :)13:43
eintopfso you selling the kit and the end-user need to build it together?13:44
eintopfokay, doesn't matter, were I need to subscribe to get an anelok? I will give you money ;)13:44
eintopfokay, let do that next month13:45
wpwrakwell, that's what i may want to do with the "alpha" units. they'll be intended for developers anyway, not for "normal" users13:45
wpwraki must have described that on the list some time ... checking ...13:45
wpwrakhere we are: http://lists.en.qi-hardware.com/pipermail/discussion/2014-May/010613.html13:48
wpwrakslight changes: making "alpha" units myself probably won't be necessary. also the number of "alpha" units may be a bit larger then than just ten.13:50
eintopfah, ok.13:51
wpwrakalso, Y-Box almost certainly won't be necessary. so this could be replaced by another anelok. (to act as radio peer)13:52
xiangfuwpwrak: your last code works just fine here.14:02
wpwrakkewl. so i need to try harder to break something :)14:17
xiangfuhappy chinese new year.15:59
kyakxiangfu: and happy long holidays :)16:00
larscparty party party!16:02
DocScrutinizer05whitequark: _whitelogger__ isn't registered16:02
whitequarkhm, actually, I can register _whitelogger now without logger downtime16:06
whitequarksince it has the __ at the end16:06
whitequarkDocScrutinizer05: i registered it16:10
whitequarkare you happy now16:10
DocScrutinizer05well, I'd be even more happy when it was in #neo900 too ;-)16:10
whitequarkit's not in #neo900?16:11
whitequarkstill joining i guess16:11
DocScrutinizer05sorry, it is, now16:11
whitequarki've fifty channels and freenode throttles me to 1 msg per 0.8s16:11
whitequarkso join takes a WHILE16:11
DocScrutinizer05[2015-02-18 Wed 17:10:43] *** ChanServ gives _whitelogger permission to talk.16:11
DocScrutinizer05whitequark: not ülanning to annoy you, just a hint: often hidemail in nickserv isn't what you want for bots16:17
DocScrutinizer05some even add metadata:16:18
DocScrutinizer05[2015-02-18 Wed 17:17:42] [Notice] -NickServ- Email      : Tim@Rikers.org16:18
DocScrutinizer05[2015-02-18 Wed 17:17:42] [Notice] -NickServ- Metadata   : url = http://apt.rikers.org/16:18
whitequarkwell /now/ i can't do anything about it16:18
wpwrakxiangfu: happy new year ! :)16:19
whitequarksince i can't impersonate the bot without shutting it down16:19
DocScrutinizer05whitequark: that's actually not an obstacle. Just autheticate against bot's account ;-)16:19
whitequarkwon't that kick the bot out?16:20
DocScrutinizer05/ns id _whitelogger MyPassWord16:20
wpwrakwhitequark: if you stand up, turn to the west, and say three times aloud "NSA, NSA, NSA", maybe they'll help you with the impersonation16:20
whitequarkhm, right, doesnt kick it out16:22
whitequarkDocScrutinizer05: ok done16:24
DocScrutinizer05pleased to help16:24
DocScrutinizer05loggers (and generally bots) with proper accountability have way higher acceptance16:24
DocScrutinizer05chanops know where to complain when bot ever starts to misbehave16:27
DocScrutinizer05/ns info _whitelogger now looks great16:30
DocScrutinizer05clearly no rogue/spam-bot16:30
arossdotmewhat do you think of external gps antennas? 16:39
arossdotmearr is it china's newyear...16:40
kristianpaulhow so arossdotme ?17:06
arossdotmehow so?17:06
arossdotmegps or china newyear?17:07
kristianpauleveything need wiring and for gps like an extenal antenns is most likelly to gibe you problems17:08
arossdotmewell i my case shall i get one sold by http://www.pulster.de/engl/index.html?linux_pda.htm17:08
arossdotmewould it be helpful for car use?17:08
arossdotmeit's just the postagge is £10+ so i'd prefer to only make one worder :D17:08
arossdotmeone order17:09
kristianpaulthat link redirects here17:10
arossdotmei can't give you the dirct link17:10
kristianpaulcars should have built-in antennas, my  personal opinion17:10
kristianpaulwhat is your apllication?17:11
arossdotmeit's in the open moko section17:11
arossdotmecar nav?17:11
arossdotmebost maybe, if i'm ever one one17:11
arossdotmeon one17:11
kristianpauland is your receiver just gps or also glonass? perhaps beidu as well :D ?17:12
arossdotmewould it make a difference woods when walking?17:12
arossdotmeit's gta0417:12
kristianpaulwe shall ask wpwrak  or DocScrutinizer05 17:13
kristianpaulnot sure what gps receiver it  uses17:14
arossdotmei think no glonass17:14
kristianpaulfor walking you probably need a IMU on board a well i bet17:14
kristianpaulyou need meter or centimet accuracy?17:14
DocScrutinizer05the gta04 has no glonass afaik17:16
arossdotmeleft or right accuracy :P17:16
arossdotme* do i turn left or right accuracy17:16
kristianpaulleft or rigght? use a compass ! ;-)17:17
kristianpaula digital ine of course17:17
arossdotmehe ha17:17
arossdotmeor a map17:17
arossdotmebut you get the idea17:17
arossdotmeor waling in a city17:17
DocScrutinizer05gta04 using the gta02 active GPS antenna internally17:17
DocScrutinizer05which is supposed to work sufficiently fine when no interference from device and no broken cable17:18
arossdotmeso how much benefit is there from the external one..17:18
DocScrutinizer05usually zilch17:18
arossdotmeok, i'll save my £10 then17:18
DocScrutinizer05external antenna my have higher gain when yiu use a huge one17:18
arossdotmewhat about the one i linked too/17:19
arossdotmein the openmoko section17:19
kristianpaulput the gt04 in your gap, thats a better antenna17:19
arossdotmeso if the gta04 head has 40%~ I';M OK17:20
arossdotmeopps caps lock17:20
DocScrutinizer05you'll need external antenna when the device is in an unfortunate location with no free sight to sky17:20
arossdotme40% sky17:20
kristianpauli meant cap sorry17:21
kristianpauleven better17:22
kristianpaulyes arossdotme 17:22
arossdotmei guess these gps antentor cables don't like being moved/bent a lot?17:23
arossdotmebest fitted and left permanently?17:23
kristianpaulbent... hmm17:24
arossdotmepacked up 17:24
arossdotmeinto storage bag17:25
kristianpauli have one of those antnna is magnetic attached, so far gold behavior after packing17:25
kristianpaulbut im carefull17:25
arossdotmeand even then i was thinking of using my diy lunch box computer for my car computer, so what would be using a usb gps. it's advantage is it has a bigger screen17:28
kristianpauloh usb gps need for sure an extension17:28
kristianpaulbut works decently with its antenna17:29
arossdotmebut a gps antentor would be of so much use17:29
arossdotmearr hmm what to do17:33
kristianpaulbuy buy buy (-:{ 17:36
DocScrutinizer05there's a bazillion of external GPS antennas available in the intarwebs17:38
DocScrutinizer05as long as the plug matches, they usually shall "just work"17:39
DocScrutinizer05I mean, nasically it's just... an antenna17:40
DocScrutinizer05(ok, it has an amp built in, but those are standard pretty much)17:41
DocScrutinizer05http://www.ebay.com/itm/28dB-LNA-Gain-1575-42MHz-RP-SMA-Male-GPS-Active-Antenna-Stronger-Singal-/291353328325 17:47
DocScrutinizer05you'll usually need a adapter17:47
DocScrutinizer05the pulster one comes with right plug it seems, maybe worth the 13 bucks more17:52
arossdotmei guess i might be usefull to have just in case18:32
