L29Ahkerio: try making a hole and evacuating the gas19:01
kerioD:19:01
L29Ahdunno if it can be done safely though as there's a risk of shorting it19:02
KotCzarnyor take a hammer and have fireworks19:02
L29Aha tiny drill might do the job19:02
KotCzarnyits dangerous ayway19:02
L29Ahanyway order a replacement first19:02
KotCzarny*anyway19:02
L29Ahalso swollen battery might indicate a malfunction in the device19:03

DocScrutinizer05kerio: L29Ah: damn NO! do not, I repeat *NOT* try to make a hole into the hull of a LiIon battery20:13
*** ced117 has quit IRC20:13
kerioDocScrutinizer05: who are you to tell me what to do20:13
DocScrutinizer05go do whatever you want20:13
DocScrutinizer05F U20:13
kerio:<20:13
KotCzarnychicken wuss20:15
L29AhDocScrutinizer05: why?20:15
L29Ahu don't like hydrogen or that's about shorting the foil layers again?20:16
DocScrutinizer05because odds are you're shorting the cell, and for _sure_ you will allow oxygen reach the Li20:16
kerioit can kinda end up in a big flame20:16
keriowhich can kinda be very fucking dangerous20:17
L29Ah20:29:16]<KotCzarny> 1500>132020:17
L29Ahis this fake numbers as usual?20:17
L29Ahnot big20:17
DocScrutinizer05all cells have a vent, so no need to drill a hiole into the hull. WTF20:18
L29Ahnope20:18
L29Ahotherwise it won't swell20:18
DocScrutinizer05BS20:18
kerioi don't think that's the reason20:18
L29Ahwhat's the reason then?20:18
kerioLiIon crystals betting out of shape or something20:19
L29Ahwell, all the swollen batteries i had were quite easy to push back, more like gas than crystals20:19
KotCzarnyl29ah: polarcell batteries usually have higher cap than 150020:19
L29Ahnever disassembled them tho20:19
KotCzarnyusually ~156020:20
DocScrutinizer05kerio: you might notice the swollen battery is "elastic", but pressure in cell is _not_ your problem20:20
kerioyeah yeah20:20
DocScrutinizer05yes, L29Ah is right, it feels like gas20:20
kerioit's a symptom of something worse20:20
kerioi'm now calibrating this old-ish bl-5j20:20
DocScrutinizer05your problem is that cell cheistry deteriorated and might eventially pierce the membrane20:21
DocScrutinizer05chemistry*20:21
keriorip cell20:22
keriowhere do i throw away the old batteries20:22
DocScrutinizer05when that happens, youi got a possibly serious problem20:22
DocScrutinizer05toxic waste20:22
KotCzarnykerio: in the fire20:22
KotCzarny:>20:22
keriodelicious toxic chemicals20:22
DocScrutinizer05or leave where you get new cells and primary batteries20:22
KotCzarnyand fireworks20:23
KotCzarnydont forget about fire20:23
keriobut i'm buying them on the internets D:20:23
DocScrutinizer05yeah, every<body does20:23
keriodo i trust this shit http://www.ebay.it/itm/Batteria-Blister-1320-mah-Originale-Nokia-BL-5J-bl5j-per-5228-5230-5800-XM-X6-N9-/181960459967?hash=item2a5db046bf:g:ZyIAAOSw5VFWIVtN20:23
KotCzarnykerio: most electronic stores allow you to leave old batteries20:23
keriooh god that's a big url20:23
kerioaww 1320mAh20:23
kerioit's one of the old ones, if it's original at all20:23
KotCzarnygo polarcell or be damned with a fake20:23
DocScrutinizer05well, try it, there's no way to tell without holding the battery in your hands (and even then...)20:24
keriowhat if i get a fake polarcell20:24
KotCzarnyunlikely20:25
kerioshould i bother checking IRL shops20:25
DocScrutinizer05I found it's not really worth wasting lots of evaluation and pondering. Get a cell which looks good by specs, test it, when it's actually nice get some more20:25
DocScrutinizer05cells >1500mAh are most likely scum20:26
DocScrutinizer05>1600 for sure are20:26
KotCzarnykerio, go tmo and search for happy polarcell users20:26
kerioi believe the polarcell is good20:26
kerioi don't know if this is a legit powercell20:27
DocScrutinizer05I got several goot "used" BL-5J at shoppee next corner20:27
keriowhat the fuck is powercell anyway20:27
*** pagurus has joined #maemo20:27
*** ced117 has joined #maemo20:27
KotCzarnypolarcell, not powercell20:27
DocScrutinizer05good*20:27
kerioer yes20:27
DocScrutinizer05advantage: when they are crap, I kick the shop owner's ass20:27
keriooh20:31
kerioi just discovered something funny20:31
keriothis weird super chinese orange battery i had20:32
kerio(which calibrated at like 1500mAh, btw)20:32
keriohas ">2400µAh" written on it20:32
keriowhich is definetely true20:32
KotCzarnyyeah yeah20:32
keriobut kind of expected20:32
KotCzarnyand will die in a month20:32
kerioi don't think you're getting it20:32
kerioDocScrutinizer05 got it20:32
KotCzarnychina is a bit far away20:33
kerioµAh, not mAh20:33
KotCzarnyahm, utf20:33
KotCzarnystill on iso here20:33
kerio2400µAh is 2.4mAh right20:36
*** lxp has quit IRC20:37
*** tanty is now known as tanty_off20:51
DocScrutinizer05yes20:52
DocScrutinizer05the category of "this salad doesn't contain asbestos"20:53
DocScrutinizer05honestly I think there are like 2 or 3 genuine cell manufacturers out there20:56
DocScrutinizer05they build lot of different stuff, but there's also stuff they cannot build20:57
kerioshould i try overclocking20:57
keriothis n900 is kind of dying anyway20:57
keriogive it a last breath of life or something20:57
DocScrutinizer05the bottleneck is RAM20:58
kerioshould i try overclocking the ram20:58
DocScrutinizer05that would actually make some sense20:58
keriocan i overclock the battery20:58
kerioto have more battery20:58
DocScrutinizer05yes, but strongly deprecated20:59
DocScrutinizer05you could charge it to 4.3 or even 4.4V20:59
DocScrutinizer05will give you an extra 100mAh, and a tenth of cycles until EOL21:00
DocScrutinizer05or even risk of cell going thermal runaway21:00
keriobrb charging the battery to 8V21:00
keriook actually how can someone do that safely?21:01
keriolong cables and some sort of blast shield?21:01
DocScrutinizer055m seem enough21:01
DocScrutinizer05in plain air21:01
keriowhat about the waste21:01
DocScrutinizer05blast shield not needed21:01
DocScrutinizer05the waste is nasty21:02
keriobut i wanted a blast shield :(21:02
DocScrutinizer05the fumes are toxic21:02
keriothe blast shield will protect me from the fumes21:02
keriohm, will the popo arrest me for freeing toxic fumes in the atmosphere21:02
DocScrutinizer05no21:02
keriothat sounds like the kind of thing one should not be able to do21:02
keriooh :<21:03
DocScrutinizer05a LiIon going pooof emits HF aka flux acid21:03
DocScrutinizer05not much, but HF is highly toxic, makes you get rubber bones21:04
DocScrutinizer05https://en.wikipedia.org/wiki/Hydrofluoric_acid21:05
*** flo_lap is now known as florian21:05
KotCzarnyrubber bones sounds awesome superpower21:06
KotCzarnyWhen the concentration of HF approaches 100%, the acidity increases dramatically because of homoassociation21:11
KotCzarnyhomo association21:11
KotCzarnyhttps://en.wikipedia.org/wiki/File:HF_burned_hands.jpg21:14
KotCzarnyfun stuff21:15
*** lxp has joined #maemo21:15
keriois that a melted finger21:25
DocScrutinizer05hmm? in wikipedia article?21:26
DocScrutinizer05btw some of the cooling agents in car aircon also emit vast amounts of HF when car is burning21:27
*** jskarvad has quit IRC21:28
KotCzarnykerio, yup, you wont notice damage till the next day21:29
KotCzarnyfun stuff21:29
KotCzarnyit wont even hurt initially21:29
DocScrutinizer05and you shouldn't heat Galden (perflour ether) above 250°C since it also emits HF then21:29
KotCzarnythen your tissues start dying21:29
*** haasn has left #maemo21:29
DocScrutinizer05ooh it seems I've been wrong with 250°C21:31
*** Kabouik has quit IRC21:33
DocScrutinizer05I still wonder what's the relevant differences for vapor phase soldering between Galden LS230 and HT23021:39
*** geaaru has quit IRC21:42
KotCzarnytalk article is funny on that acid21:48
*** ced117 has quit IRC21:57
*** bluto271828 has joined #maemo22:12
*** lxp has quit IRC22:20
bluto271828I need a fully mobile terminal to remotely access an ncurses tui over ssh. Thinking about buying a refurbished N900 sold on ebay. You all probably follow this stuff. Is there a better option? I need a keyboard, 3G/LTE networking and a true xterm+ssh. smaller the better so can keep with me. sorry if not good place to ask but doesn't exactly look over active so what the hell. why not ask you guys22:22
*** lxp has joined #maemo22:22
KotCzarnybluto271828: n900 is good, kb is not bad22:26
KotCzarnynetwork wise it's nice too22:26
KotCzarnyfor low memory hungry applications it's very useful22:26
KotCzarnysubnotebook would beat any mobile keyboard tho22:27
KotCzarnytry looking for old toshibas/sonys22:27
keriothe new 9" ipad pro with an apple smart cover22:27
kerio:D22:27
KotCzarnyipad, pah22:28
kerioipahd22:28
bluto271828i want real keys22:28
KotCzarnyhow small shall the device be?22:29
bluto271828i really need in pocket so I liked old sharp netwalker22:30
KotCzarnyhttp://img.bhs4.com/10/7/107C483D6B685CC0F60C9DCDE40F6B65BCA72272_large.jpg22:30
bluto271828but this doesn't have cell capability22:30
KotCzarnykeyword for you: umpc22:30
bluto271828yes I know22:30
bluto271828but I'm wondering if anything more recent22:31
bluto271828and linux friendly ideally22:31
KotCzarnyn900 is not recent, 2009 era, 256M of ram, tiny part of it really available22:31
bluto271828though non-linux is ok if I have true terminal22:31
KotCzarnybut real linux22:31
KotCzarnywhich is really limiting mobile options22:31
KotCzarnyhttp://www.brighthub.com/computing/hardware/articles/43814.aspx22:32
bluto271828yeah do you think they will actually send me one if I buy what they are listing on ebay for sale n90022:32
bluto271828my netwalker is 201022:32
bluto271828vaio is also discontinued correct22:33
KotCzarnyyou can try pandora, it's a bit more recent22:33
bluto271828basically I have a mission critical app that runs in a screen session and performs a heartbeat with a human22:33
bluto271828this app is ncurses based and can navigate very complex commands and reports22:34
bluto271828extremely quickly22:34
KotCzarnywell, used n900 can be had for ~20-40usd22:34
KotCzarnygrab it, test it, sell it if not good enough22:34
bluto271828ok it is 100 on ebay22:35
KotCzarnytoo much22:35
bluto271828that is what I was going to do. or maybe that is refurbished22:35
KotCzarnyif you have friends in europe, try there22:35
KotCzarnyit's much more popular here22:35
bluto271828but I see there is this IRC for the maemo software so I figure ask if something like that but obsurce that is newer22:35
bluto271828is it easy to upload/modify22:36
bluto271828like is bootloader GRUB or how you can put your own stuff?22:36
bluto271828I mean ideally if it is accessible I would drop it down to framebuffer terminal for example22:37
KotCzarnyyou can stick to maemo os22:37
KotCzarnyit's really nice/good22:37
bluto271828ok so I'll go get one and come back when i'm trying to set it up. they should be unlocked and work on US cell system like a tmobile sim or whatever22:39
KotCzarnysleepy time, nite nite22:39
bluto271828sorry I talked to much?22:39
bluto271828last question. how many character row and column do you think you can get? or what is best resolution an n900 will run in22:40
bluto271828ok. i see it. nevermind. TFT 800 × 480 resolution22:43

DocScrutinizer05((character row and column)) depends on font size in osso-xterm, which you can switch on the fly with volume rocker switch - very convenient (though your ncurses app will prolly not cooperate with on the fly fontsize change)23:59
