uvoswell i solder some wires to my adapter pcb on one end and to some nikel strips on the other and then spot welded those to the battery tabs of a nexus 4 battery00:13
uvosbut others have had sucess with soldering the eb41 pcb to the tabs of a nexus 4 battery00:13
uvossoldering to the tabs is not ideal but its ok if you keep the heat that sinks into the battery down00:14
uvosalso keep the nickel strips that are spotwelded to the battery, the main tabs are sometimes stainless steel and are going to be hard to solder to without special flux00:15
buZznorayr: it helps to plonk heatsinks on/below batteries you're soldering to , to 'wick' away the heat somewhat10:34
buZzuvos__: i think the maintabs of those LG cells are lithium :O10:34
buZzone of my tabs had the nickel come off during rebuild, and its mad hard to solder to10:34
buZzi think i need silversolder for it10:35
uvos__nah lithium is to reactive10:43
uvos__soldering to lithium in a air-water atmosphere would be more than hard ÖP10:44
buZz^_^10:48
Wizzupnorayr: btw the amazon link you sent to me doesn't seem to sell anymore10:49
Wizzupnorayr: or maybe they just don't sell to me or something10:49
Wizzupuvos__: btw I am planning to move to leste as my daily driver at the end of the year, any chance you could help me out a bit in the next two weeks to get a telepathy backend in sphone?12:01
uvos__Wizzup: sure, in advisary capcatiy, i dont have that mutch time at the moment12:03
uvos__but do ask away about how things work in sphone12:04
uvos__i pretty mutch use the d4 as my primary phone allreay, the android phone only tags along as a whatsapp device at this point12:05
Wizzupneat :)12:05
Wizzupuvos__: with hildon?12:05
uvos__yes12:05
Wizzupcool12:06
siceloWizzup: we're already running dnsmasq for some reason in Leste. i think it would be a good idea to also use it to provide dhcp on usbnet.13:16
Wizzupyeah, probably sensible13:18
Wizzupuvos__: well one thing, we would have multiple telepathy accounts that can call13:56
Wizzupuvos__: telepathy-ring, telepathy-rakia, telepathy-gabble13:56
Wizzupand we can have multiple accounts for the latter, maybe even for the first one too13:56
Wizzuphow would that fit in sphone?13:57
uvos__Wizzup: perfectly fine14:01
uvos__every module can register any number of backends (backend == proctoll in sphone more or less)14:01
uvos__it just tells sphones what mimes it supports and what capabilites the backend has (call text etc)14:02
uvos__then when sphone is opend with a mime ie tel://number it will select the backend that claims to support this mime to place the call14:03
uvos__sphones dialer will also show all the procols with names in the selection dropdown when placing a call14:03
uvos__see https://github.com/maemo-leste/sphone/blob/eacc386bf976e999a0c2a0d0a536cebe5b7f788d/src/modules/commtest.c#L4614:05
uvos__https://github.com/maemo-leste/sphone/blob/eacc386bf976e999a0c2a0d0a536cebe5b7f788d/src/modules/commtest.c#L20114:05
uvos__https://github.com/maemo-leste/sphone/blob/eacc386bf976e999a0c2a0d0a536cebe5b7f788d/src/modules/commtest.c#L19514:05
uvos__the id you get you are then to save and when a call comes down on call_dial_pipe you are to check if you are supposed to handle this call by matching to your ids see https://github.com/maemo-leste/sphone/blob/eacc386bf976e999a0c2a0d0a536cebe5b7f788d/src/modules/commtest.c#L10714:07
uvos__if so you shal handle the call14:07
Wizzupuvos__: can you register new ones at runtime?14:07
uvos__yes14:07
Wizzupand remove as well I assume14:08
uvos__yes14:08
uvos__2 problems in current sphone we still ned to solve is however:14:08
Wizzupso if there are multiple telepathy-rakia accounts (sip://), how does it know which one to pick14:08
Wizzupthere's also a question of which accounts are online, but the gtk rtcom stuff+abook solves this, but I guess that's too hildon dependent?14:09
uvos__you get the full url in the module14:09
uvos__so externaly ofc its username@14:09
uvos__otherwise theres no way ofc14:09
uvos__sphone only gets the mime as given by firefox gnome-conteacts etc14:10
uvos__also14:10
uvos__1. the dialer ui currently allows to you only enter numbers, this is only a ui problem14:10
uvos__2. the ui dosent know that it should only offer to send sms via backends that claim to support it (ie it will try to send messages with any backend)14:10
uvos__i gues you could add support pop up a dialog when a mime is to be handled by multiple "backends" (ie because of multiple accounds) and allow the user to select that way14:16
uvos__otherwise in a nomal sip:// mime as provided by the external applications the information is just not there to know14:16
Wizzupright, tel:// can also be handled by sip14:21
uvos__yes14:58
freemangordonuvos__: re battery leads heat sink - I think one should try extremely hard to be able to overheat the battery from soldering, those flat wires that come from the battery are about 1cm long and very thin16:02
uvos__freemangordon: overheating the battery is not the problem16:03
freemangordonbut? electronics?16:03
uvos__the probem is that the polimer that the leads are sandwiched in survive finite temperature capacity, and the thermal expansion of the lead can delaminate the interface.16:04
uvos__the actuall battery will be fine (unlike when soldering to li-ion cells like 18650 etc)16:04
uvos__but just do be an idiot and hold the iorn there for several minutes16:05
freemangordonright, but in order this to happen, you should have high enough temperature (at least 80 deg I would guess) at the end of 1cm long and thin stainless steel wire16:05
uvos__and youl be fine16:05
uvos__freemangordon: right16:05
freemangordonto me this can't really happen under normal soldering conditions16:06
freemangordonif you take a lighter.. well :)16:06
uvos__well if people have trouble geting the solder to wet16:06
uvos__then they might be messing around with the iorn for a while16:06
uvos__then i could see it16:06
freemangordonstill, this happens 1 cm away from the weak spot16:06
freemangordonbut I agree one should be careful16:07
freemangordonjust trying to say it is not *thet* fragile16:07
freemangordon*that*16:07
freemangordonWizzup: tomorrow will try to finish HAM ui16:08
freemangordonfortunately I have an idea what needs to be done16:09
freemangordonjust didn;t have time today16:09
Wizzupfreemangordon: ok, we cna also just not have the background16:23
freemangordonno, it is just that it is picky, but I'll fix it16:31
