**** BEGIN LOGGING AT Thu Feb 05 02:59:59 2015
Feb 05 05:52:38 <Maxdamantus> Hm. I think I have a charging thing with a USB port that's sensitive to usage of the data pins.
Feb 05 05:54:43 <Maxdamantus> It has its own (unreliable) USB cable that I suspect doesn't do anything with the pins from the A end and just has the microUSB data pins shorted.
Feb 05 05:55:52 <Maxdamantus> with a normal cable, plugging it into the N900 causes it (the power source) to go into some sort of panic mode where it flashes an LED.
Feb 05 05:56:25 <Maxdamantus> and shorting the data pins on it causes it to do it for other devices too.
Feb 05 05:56:35 <Maxdamantus> Hm.
Feb 05 06:01:03 <Maxdamantus> Actually, that last bit isn't true.
Feb 05 06:01:33 <Maxdamantus> Meh, maybe it is.
Feb 05 06:14:26 * Maxdamantus wonders if he should try scratching off the PCB lead things that seem to go to the data pins.
Feb 05 06:21:03 * Luke-Jr wonders if his USB port is breaking despite being soldered down :|
Feb 05 06:23:51 <Maxdamantus> I'd probably open it and see.
Feb 05 06:33:56 <Maxdamantus> Seems to have made it worse.
Feb 05 06:41:32 <Maxdamantus> Maybe PCB isn't meant to be re-etched manually.
Feb 05 06:43:28 <Luke-Jr> Maxdamantus: well, jigglign the cable "fixes" it for now..
Feb 05 06:43:43 <Luke-Jr> and I'm about to travel, so don't really want to risk anything
Feb 05 06:47:42 <Maxdamantus> Hm. What I intended to do seems to have worked.
Feb 05 06:48:01 <Maxdamantus> but it seems to be sensitive and randomly go into its panic mode.
Feb 05 06:48:46 <Maxdamantus> Maybe because the bits from the edge of my etching manage to make contact.
Feb 05 06:53:22 <uhhimhere> hey guys what would be the criteria to be able to run maemo on a default android device?
Feb 05 06:54:05 <Maxdamantus> uhhimhere: It's not going to.
Feb 05 06:54:36 <uhhimhere> how come
Feb 05 06:54:43 <uhhimhere> theyre both arm based
Feb 05 06:54:56 <uhhimhere> and run on linux
Feb 05 06:55:33 <Luke-Jr> Neither Maemo nor Android run on vanilla Linux
Feb 05 06:56:07 <uhhimhere> so maemo cant use the lates kernel 
Feb 05 06:56:19 <Luke-Jr> also, Maemo is dead
Feb 05 06:56:25 <Luke-Jr> for years now
Feb 05 06:56:39 <Maxdamantus> afaik the standard Hildon binaries won't run without the particular OMAP graphics chip.
Feb 05 06:57:11 <uhhimhere> Luke-Jr: there are more people in this room than say #sgs5
Feb 05 06:57:37 <uhhimhere> Luke-Jr: or sailfish
Feb 05 06:58:11 <uhhimhere> Luke-Jr: in fact the one that comes closest is ubuntu-touch
Feb 05 06:58:17 <uhhimhere> so it cant be that dead
Feb 05 06:58:19 <freemangordon> Luke-Jr: hmm, my n900 doesn't show signs of being dead :)
Feb 05 06:58:20 <Luke-Jr> maybe because there's no alternative to Maemo yet?
Feb 05 06:58:34 <freemangordon> most probably
Feb 05 06:58:42 <Luke-Jr> uhhimhere: also keep in mind Maemo is closed source, so an active community can't really maintain it
Feb 05 06:59:10 <freemangordon> Luke-Jr: there were some developments on those closed bits recently
Feb 05 06:59:15 <Luke-Jr> oh?
Feb 05 06:59:29 <freemangordon> you know we have mce?
Feb 05 06:59:37 <Luke-Jr> I thought Nokia had washed its hands of Maemo entirely
Feb 05 06:59:40 <Luke-Jr> mce?
Feb 05 06:59:43 <freemangordon> and 2/3 of pulseaudio-nokia?
Feb 05 06:59:45 <freemangordon> ~mce
Feb 05 06:59:45 <infobot_> MCE = Machine Check Exception.  Mode Control Entity
Feb 05 07:00:03 <Maxdamantus> Nokia isn't the only entity with an interest in it.
Feb 05 07:00:13 <Luke-Jr> Maxdamantus: it's the only entity with the code and copyright
Feb 05 07:00:36 <freemangordon> Luke-Jr: https://gitorious.org/community-ssu/mce/source/09d83e80325293a8855cd8c02dc7c5311863f27f:
Feb 05 07:00:36 <Luke-Jr> (at least, I don't think freemangordon is saying *all* of it was released..)
Feb 05 07:00:45 <freemangordon> nothing was released
Feb 05 07:00:52 <freemangordon> but lots was REed
Feb 05 07:01:13 <Luke-Jr> i c
Feb 05 07:01:23 <freemangordon> Luke-Jr: https://gitorious.org/pulseaudio-nokia/pulseaudio-nokia/source/b11715c65867ce3ac4108237c70bcd2023df9399:
Feb 05 07:01:47 <Luke-Jr> oh, is this for Neo900 stuff?
Feb 05 07:01:54 <freemangordon> yep
Feb 05 07:02:00 <freemangordon> stock maemo blobs
Feb 05 07:02:11 <freemangordon> one more remains though
Feb 05 07:03:01 <uhhimhere> so i take it dropping a couple of GSM/CDMA RF chips onto an open pandora to make it a phone-book is out of the question?
Feb 05 07:03:19 <uhhimhere> wrong channel
Feb 05 07:03:24 <Luke-Jr> uhhimhere: Pyra?
Feb 05 07:04:12 <freemangordon> Luke-Jr: sure, there are more to go, but they can be REed on as-needed basis
Feb 05 07:04:43 <freemangordon> as happened with https://gitorious.org/community-ssu/nokiamaps-navigation-provider/source/5142e28be6e3c61ae962ca282c94890c33a3f7be: for example
Feb 05 07:04:56 <uhhimhere> freemangordon: i thought maemo 5 was community maintained and the source was open
Feb 05 07:05:47 <freemangordon> uhhimhere: yes, it is community maintained, but lots of stuff, esp on the UI side is closed
Feb 05 07:06:19 <uhhimhere> heh
Feb 05 07:06:27 <uhhimhere> whatbout mer?
Feb 05 07:06:55 <freemangordon> what about it? last time I tried Nemo on n900 it was as fast as a snail
Feb 05 07:07:28 <Luke-Jr> lol
Feb 05 07:07:38 <freemangordon> I don;t even think they support N900 recently
Feb 05 07:12:28 <uhhimhere> freemangordon: is that nemo-mobile that you tried
Feb 05 07:13:22 <freemangordon> I guess, there is (or was) an image for N900 floating around the inet
Feb 05 07:17:51 <uhhimhere> how does the n950 compare w/ the n900
Feb 05 07:17:55 <uhhimhere> thoughts?
Feb 05 07:18:40 <freemangordon> it does not :)
Feb 05 07:18:53 <freemangordon> both HW and SW wise
Feb 05 07:19:33 <freemangordon> the only thing n950 is better than N900 is the design - this thing looks great
Feb 05 07:19:59 <uhhimhere> can it run maemo 5
Feb 05 07:20:05 <freemangordon> afaik no
Feb 05 07:20:10 <freemangordon> well, it can
Feb 05 07:20:24 <freemangordon> but I am not aware of anyone trying it
Feb 05 07:20:36 <freemangordon> it just makes no sense
Feb 05 07:21:08 <freemangordon> no FMTX, lack of storage, capacitive screen, bad radios, bad screen, ets
Feb 05 07:21:15 <freemangordon> *etc
Feb 05 07:21:40 <uhhimhere> but it looks great XD
Feb 05 07:21:47 <freemangordon> yeah, looks great
Feb 05 07:22:04 <Maxdamantus> Yay. I think I've got it to work.
Feb 05 07:22:14 <uhhimhere> who in their right mind would want to drive around in a formula one car when they could as well in a delorean?
Feb 05 07:23:03 <Maxdamantus> though if I touch the current break in the PCB path it panics again.
Feb 05 07:23:13 <Maxdamantus> will probably just put hot glue on it.
Feb 05 07:25:14 <uhhimhere> Maxdamantus, what are you doing
Feb 05 07:26:09 <Maxdamantus> Getting some charger thing to work properly.
Feb 05 07:38:42 * Maxdamantus wonders if it heated up before he started messing with it.
Feb 05 07:41:01 <uhhimhere> Maxdamantus: would you be able to identify a serial line on a PCB if you saw one?
Feb 05 07:41:15 <uhhimhere> im trying to think of where to tap in for console access on a pcb
Feb 05 07:41:28 <Maxdamantus> No.
Feb 05 07:41:31 <freemangordon> uhhimhere: what device?
Feb 05 07:41:55 <uhhimhere> GT-S7580
Feb 05 07:41:59 <uhhimhere> SAMSUNG
Feb 05 07:42:06 <freemangordon> oh
Feb 05 07:42:22 <uhhimhere> does Imgur not accept .svg?
Feb 05 07:43:18 <Maxdamantus> I wouldn't imagine so.
Feb 05 07:43:31 <Maxdamantus> SVGs can have code in them.
Feb 05 07:50:16 <Wizzup> and very painful recursion
Feb 05 07:53:36 <uhhimhere> could you run ubuntu touch on the n900
Feb 05 07:53:50 <Wizzup> Luke-Jr: the n900 has quite some features working on mainline though
Feb 05 07:53:54 <Wizzup> (kernel)
Feb 05 07:54:25 <uhhimhere> so are the neo900 guys coming up with a new OS or are they sticking with maemo5
Feb 05 07:54:35 <Wizzup> the bring you the hw
Feb 05 07:54:44 <Wizzup> not so much a full usable env
Feb 05 07:54:59 <Wizzup> but I think FPT (?) was aiming for maemo
Feb 05 08:06:09 <uhhimhere> Maxdamantus: https://imgur.com/a/lw0Pw
Feb 05 08:06:15 <uhhimhere> freemangordon: https://imgur.com/a/lw0Pw
Feb 05 08:21:43 <Maxdamantus> Electricity is weird.
Feb 05 08:57:58 <zGrr> moin :)
Feb 05 10:41:51 <Maxdamantus> Hm. This looks bad.
Feb 05 10:41:52 <Maxdamantus> [24566.359069] bq2415x-charger 2-006b: Overvoltage protection (chip fried)
Feb 05 10:44:34 <kerio> lp0 on fire
Feb 05 10:45:27 <APic> *g*
Feb 05 10:46:40 <bencoh> wtf
Feb 05 10:50:56 <Maxdamantus> Well, seems to still work.
Feb 05 10:51:11 * Maxdamantus wonders what the "chip fried" message is meant to mean.
Feb 05 10:52:01 <bencoh> scare you away and make you stop torturing it, maybe :D
Feb 05 10:52:01 <uhhimhere> Maxdamantus, probably your lunch ready
Feb 05 10:52:15 <Maxdamantus> Odd time for lunch.
Feb 05 10:52:17 <Maxdamantus> Thu Feb  5 23:52:08 NZDT 2015
Feb 05 10:52:19 <bencoh> "lemme alone, I'm dying, pretty plz" :p
Feb 05 10:52:35 <bencoh> what did you do to it ?
Feb 05 10:52:55 <Maxdamantus> I plugged it into something without testing its voltage.
Feb 05 10:53:12 <Maxdamantus> Though I tried plugging some cheaper devices in beforehand and they didn't complain.
Feb 05 10:53:39 * Maxdamantus will try to figure out how to use this multimeter.
Feb 05 10:55:35 <uhhimhere> Maxdamantus, set to auto
Feb 05 10:57:14 <Maxdamantus> I think I've figured it out.
Feb 05 10:57:29 <Pali> echo reset > mode
Feb 05 10:57:31 <Maxdamantus> I put it onto the 200 thing in the V-... section
Feb 05 10:57:52 <bencoh> hmm
Feb 05 10:58:16 <Maxdamantus> Seems to be 7.6 V.
Feb 05 10:58:25 <Pali> reset will clear that overvoltage flag and reset kernel driver to charge again
Feb 05 10:58:29 <Maxdamantus> though I'm obviously not very good at this.
Feb 05 10:58:42 <Maxdamantus> It is charging again, but I rebooted it.
Feb 05 10:58:42 <bencoh> oh btw, is nokia bme supposed to shutdown device when it thinks battery is at 0mAh ?
Feb 05 10:58:51 <Maxdamantus> because it seemed to freeze the screen.
Feb 05 10:58:55 <bencoh> or does it wait for a certain voltage/flag ?
Feb 05 10:59:10 <bencoh> (bme fucked up my calibration yesterday night)
Feb 05 10:59:16 <Pali> bencoh, nokia bme monitor only voltage and current
Feb 05 10:59:20 <Pali> nothing more
Feb 05 10:59:37 <Pali> and from these two data it calculate (somehow) percentage of battery
Feb 05 10:59:43 <Pali> and also mAh
Feb 05 10:59:45 * Maxdamantus should've done electronics in high school.
Feb 05 10:59:50 <bencoh> which means that their formula is off for this battery I guess
Feb 05 11:00:06 <Pali> nokia bme is toxic
Feb 05 11:00:13 <bencoh> haha, yeah
Feb 05 11:00:15 <Pali> it store state infomation to CAL
Feb 05 11:00:32 <bencoh> well I'm willing to ditch it but I still need to calibrate first
Feb 05 11:00:38 <bencoh> oh, and ... one thing that bothers me
Feb 05 11:00:41 <Pali> so it can "remember" some data used for guessing mAh
Feb 05 11:01:11 <bencoh> once you get rid of nokia bme, you only have bq27xx to get battery info ... which will remain silent if CI=1
Feb 05 11:01:41 <Pali> yes, then you will use data from bq27200 chip
Feb 05 11:01:47 <bencoh> meaning that if you remove the battery for some reason (SIM swap for instance) you wont have any battery indicator until you recalibrate
Feb 05 11:02:15 <Pali> yes
Feb 05 11:02:39 <bencoh> does bq27200 stores its state somewhere ?
Feb 05 11:02:46 <Pali> yes, in chip
Feb 05 11:02:51 <bencoh> ram ?
Feb 05 11:02:55 <bencoh> or nvram ?
Feb 05 11:03:11 <Pali> do not remember
Feb 05 11:03:21 <Pali> but n900 has backup battery
Feb 05 11:03:23 <bencoh> I'll have to reread the ti spec
Feb 05 11:03:36 <Maxdamantus> Does anyone's backup battery still work?
Feb 05 11:03:39 <bencoh> hmm, does your backup battery work ? :D
Feb 05 11:03:41 <Pali> and that is used in case when you remove big bl5j bayttery
Feb 05 11:03:51 <Pali> my is probably dead now :-)
Feb 05 11:03:54 <Pali> need to replace it
Feb 05 11:03:58 <bencoh> same here ;)
Feb 05 11:04:33 <Maxdamantus> So you know that it resets (and uses ILMD) when you take the battery out (if the backup battery is also dead)?
Feb 05 11:04:55 * Maxdamantus guesses he hasn't taken his battery out since using bme-replacement.
Feb 05 11:05:24 <Maxdamantus> for more than the second or so I'm able to.
Feb 05 11:06:17 <Maxdamantus> Oh, that's what you can't remember, nvm.
Feb 05 11:11:07 <Pali> "The bqJUNIOR stores all calculated information in RAM, which is backed up by the voltage on the RBI input."
Feb 05 11:11:29 <bencoh> RBI being ?
Feb 05 11:12:20 <bencoh> oh, register backup unit
Feb 05 11:12:37 <Pali> "The RBI input pin is used with an external capacitor to provide backup potential to the internal registers when VCC drops below V(POR)."
Feb 05 11:14:11 <bencoh> RBI is connected to C1135 (100n) on n900
Feb 05 11:14:15 <Pali> "The device enters hibernate mode when VCC drops below V(POR). VCC must be raised above V(POR) in order to exit the hibernate mode. If RBI voltage does not drop below 1.3 V, RAM content is maintained and allows retention of NAC, LMD, CYCL, CYCT, and the CI flag after VCC is raised above V(POR)."
Feb 05 11:14:33 <bencoh> so ... all we have is a small capa
Feb 05 11:14:51 <Pali> good
Feb 05 11:15:06 <bencoh> dunno how long it's supposed to keep at 1.3V
Feb 05 11:15:20 <bencoh> s/keep/stay/
Feb 05 11:15:20 <infobot_> bencoh meant: dunno how long it's supposed to stay at 1.3V
Feb 05 11:16:08 <bencoh> looks like they just implemented the typical application circuit
Feb 05 11:16:13 <bencoh> (regarding this)
Feb 05 11:20:16 <bencoh> RBI cant draw more than 20nA, C=100n, and VPOR=2.6V
Feb 05 11:51:01 <antranigv> \o
Feb 05 11:51:17 <antranigv> is it possible to port maemo to another device ?
Feb 05 11:52:43 <kerio> hopefully it'll be ported to the neo900 when it's out
Feb 05 11:52:46 <kerio> but that's kinda cheating
Feb 05 11:52:54 <bencoh> 07:53 < uhhimhere> hey guys what would be the criteria to be able to run maemo on a default android device?
Feb 05 11:52:57 <bencoh> 07:54 < Maxdamantus> uhhimhere: It's not going to.
Feb 05 11:53:24 <bencoh> why do they all want to port maemo today ? ^^
Feb 05 11:53:57 <kerio> i dunno
Feb 05 11:54:06 <antranigv> it's always the best :)
Feb 05 11:54:48 <uhhimhere> its the next only true and tested mobile platform
Feb 05 11:55:00 <chem|st> bencoh: it is a good OS, very mature compared to android
Feb 05 11:55:25 <antranigv> the point is, maemo is perfect, but N900's hardware is old
Feb 05 11:55:41 <antranigv> so think like, better hardware, but still maemo
Feb 05 11:56:04 <chem|st> uhhimhere: you'd need to be able to run maemo on top of android kernel and stuff, just like sailfish
Feb 05 11:56:05 <kerio> that's like the whole point of the neo900, yes :)
Feb 05 11:56:47 <antranigv> but neo900's hardware is not that new. like, camera, or screen
Feb 05 11:57:01 <antranigv> just cz they are using N900s case of corse
Feb 05 11:57:09 <antranigv> which is totaly sexy ^_^
Feb 05 11:57:13 <antranigv> and expancive :P
Feb 05 11:57:39 <antranigv> why not do foundraising like Jolla ? that will be faster. i think.
Feb 05 12:04:21 <sixwheeledbeast> antranigv: These questions have been covered on the talk.maemo.org and at #neo900, BTW. 
Feb 05 12:06:31 <antranigv> oh there is a channel, thanks sixwheeledbeast!
Feb 05 12:07:06 <sixwheeledbeast> antranigv: :nod: also check out the neo900 section on TMO.
Feb 05 12:22:06 <Maxdamantus> Can I see the USB (charging) amperage somewhere?
Feb 05 12:24:50 <Maxdamantus> I think the charging cable I mentioned a while ago has a resistor.
Feb 05 12:25:34 <honestly> buy a usb charger doctor
Feb 05 12:26:03 <Maxdamantus> I don't like buying things.
Feb 05 12:26:59 <honestly> ¯\_(ツ)_/¯
Feb 05 12:27:12 <Maxdamantus> I think my multimeter indicated that it allowed 0.33 A through it.
Feb 05 12:27:30 <Maxdamantus> Though I don't really trust my newly-tested multimeter skills.
Feb 05 12:28:00 * Maxdamantus hasn't tried with a normal cable.
Feb 05 12:30:14 <kerio> Maxdamantus: USB mandates 0.5A
Feb 05 12:31:32 <Maxdamantus> I'm pretty sure the device it came with doesn't care what USB mandates.
Feb 05 12:32:28 <Maxdamantus> Since it originally didn't charge my N900 with a normal USB cable.
Feb 05 12:32:40 <uhhimhere> Maxdamantus, couldnt you output the driver values
Feb 05 12:32:59 <Maxdamantus> uhhimhere: hopefully.
Feb 05 12:33:04 <Maxdamantus> but dunno where to look.
Feb 05 12:33:13 <Maxdamantus> /sys/class/power_supply/bq24150a-0/charge_current seems to always be 550
Feb 05 12:33:21 <Maxdamantus> even when it's not plugged in.
Feb 05 12:33:47 <Maxdamantus> that seems like the most sensible name for what I'm looking for.
Feb 05 12:34:27 <Maxdamantus> Maybe that's meant to be configurable.
Feb 05 12:34:42 <Maxdamantus> so maybe if I write 330 into it I'll be able to use the charger with a normal cable.
Feb 05 12:35:05 <Maxdamantus> Doesn't seem to be.
Feb 05 12:36:14 * Maxdamantus looks at the source code.
Feb 05 12:41:58 <Maxdamantus> Looks like it is.
Feb 05 12:43:18 <uhhimhere> i think your best best really is your multimeter
Feb 05 12:43:34 <uhhimhere> its an "unbiased opinion"
Feb 05 12:43:48 <uhhimhere> heres a stupid question...did you break the circuit
Feb 05 12:44:21 <uhhimhere> to measure the current
Feb 05 12:44:35 <uhhimhere> you gotta measure current in series....
Feb 05 12:46:08 <Maxdamantus> I didn't have anything actually running on it.
Feb 05 12:46:29 <uhhimhere> yeah you gotta have something running first
Feb 05 12:46:45 <Maxdamantus> I suspect that's what the two different contacts on the multimeter are for.
Feb 05 12:46:55 <honestly> ...
Feb 05 12:47:07 <honestly> ...no?
Feb 05 12:47:11 <uhhimhere> im sorry back up
Feb 05 12:47:20 <uhhimhere> did you have a load on the usb port?
Feb 05 12:47:42 <Maxdamantus> No. Just a multimeter, with the USB connected to the "10ADC" pin.
Feb 05 12:47:49 <uhhimhere> lol
Feb 05 12:47:53 <uhhimhere> ok
Feb 05 12:48:05 <Maxdamantus> as opposed to the "VΩMA" pin.
Feb 05 12:48:21 <uhhimhere> nananana
Feb 05 12:48:43 <honestly> this kills the usb
Feb 05 12:48:45 <uhhimhere> you gotta load it and then put it into A(amps)
Feb 05 12:48:52 <honestly> well, it shouldn't
Feb 05 12:49:11 <honestly> but really putting a multimeter inside a usb circuit isn't easy
Feb 05 12:49:24 <honestly> get a usb charger doctor
Feb 05 12:49:28 <uhhimhere> it is you just gotta cut up a a USB cable
Feb 05 12:49:37 <Maxdamantus> I think I've shortcircuited my USB before and restarted it by reloading *hci_core
Feb 05 12:49:55 <Maxdamantus> er, *hci_hcd
Feb 05 12:50:26 <uhhimhere> ok so let me get this straight
Feb 05 12:50:46 <uhhimhere> your trying to measure the USB output power by hooking it up to a meter directly?
Feb 05 12:51:20 <Maxdamantus> Kind of.
Feb 05 12:51:24 <uhhimhere> meters have infinite(close to) impedance; which is why it wont(shouldnt) draw any current. Its not meant to act as a load
Feb 05 12:51:36 <uhhimhere> you need to load it
Feb 05 12:51:38 <honestly> uhhimhere: no.
Feb 05 12:51:52 <Maxdamantus> uhhimhere: I think it depends what contact you're using.
Feb 05 12:51:52 <uhhimhere> orly?
Feb 05 12:52:04 <Maxdamantus> I think one of them draws as much current as it can (up to 10A)
Feb 05 12:52:10 <honestly> when you put a multimeter into current measure mode it has close to zero impedance.
Feb 05 12:52:12 <Maxdamantus> and the other draws as little as possible.
Feb 05 12:52:16 <honestly> Maxdamantus: no.
Feb 05 12:52:51 <honestly> Maxdamantus: the only difference between the high-amperage and low-amperage terminals, when in current measure mode, is the fuse.
Feb 05 12:53:17 <Maxdamantus> Ah.
Feb 05 12:54:39 <honestly> a multimeter in current measure mode is a dead short.
Feb 05 12:55:56 <Maxdamantus> Ah right, my driver indicated that.
Feb 05 12:56:03 <Maxdamantus> [2601747.694160] hub 1-1:1.0: over-current condition on port 1
Feb 05 12:56:34 <Maxdamantus> So why did my multimeter just say 0.33?
Feb 05 12:56:54 <honestly> who knows?
Feb 05 12:57:12 <honestly> i don't know how the circuitry in the usb port is laid out
Feb 05 12:57:35 <Maxdamantus> Maybe my USB chip limits it to that when it notices the "over-current condition"
Feb 05 12:58:31 <Maxdamantus> I imagine USB should be expected to be resilient to shortages on modern motherboards.
Feb 05 12:59:48 <uhhimhere> Maxdamantus, yeah well in anycase again electricity 101. you wanna measure current. You break the circuit. Or use a clamp
Feb 05 12:59:53 <uhhimhere> hall effect etc
Feb 05 13:00:08 <uhhimhere> load it with something that its meant to drive
Feb 05 13:00:22 <uhhimhere> and break the circuit with the meter or clamp it
Feb 05 13:00:35 <Maxdamantus> Would have to find more USB cables to take apart.
Feb 05 13:01:36 * Maxdamantus is using rolled-up aluminium foil to connect things to the terminals on his multimeter.
Feb 05 13:01:45 <honestly> the usb limits current anyway if there is no enumeration
Feb 05 13:02:21 <uhhimhere> why do you wanna know anyways?
Feb 05 13:03:17 <honestly> i.e. there's no proper usb device connected
Feb 05 13:04:41 <Maxdamantus> I want to know what's special about the USB cable that came with some Chinese solar power charger thing.
Feb 05 13:05:12 <uhhimhere> its made in china?
Feb 05 13:05:20 <Maxdamantus> Yes.
Feb 05 13:05:27 <uhhimhere> thats special enough?
Feb 05 13:06:09 <honestly> Maxdamantus: so just measure the resistance of the cable?
Feb 05 13:06:48 <Maxdamantus> Yeah, I can probably do that with some more aluminium foil and cardboard.
Feb 05 13:06:59 <uhhimhere> TF
Feb 05 13:07:01 <uhhimhere> lol
Feb 05 13:07:19 <uhhimhere> you forgot cookie dough to hold everything together
Feb 05 13:07:30 <uhhimhere> seriously where do you live? in martha stewarts kitchen?
Feb 05 13:08:08 <Maxdamantus> New Zealand, but I don't normally buy these sorts of things.
Feb 05 13:11:33 <uhhimhere> if you had half a brain to buy a multimeter and not build a galvanometer im pressed to believe that you dont have any wires lying around
Feb 05 13:12:02 <Maxdamantus> Someone was throwing the multimeter out.
Feb 05 13:12:27 <uhhimhere> lol
Feb 05 13:12:27 <uhhimhere> k
Feb 05 13:12:32 <uhhimhere> Maxdamantus, http://www.mjmwired.net/kernel/Documentation/usb/power-management.txt#509
Feb 05 13:12:36 <uhhimhere> interesting
Feb 05 13:14:00 <Maxdamantus> Indeed.
Feb 05 13:26:56 <uhhimhere> Maxdamantus, : http://yosemitefoothills.com/Electronics/USBProgrammingSummary.html
Feb 05 13:27:05 <uhhimhere> The hub controller detects the device, reads its USB descriptors, and makes sure it doesn't demand too much power.
Feb 05 13:27:37 <uhhimhere> well there ya go
Feb 05 13:28:05 <Maxdamantus> "demand" as in "ask for"?
Feb 05 13:28:12 <Maxdamantus> or "use"
Feb 05 13:28:18 <Maxdamantus> I suspect it means ask for.
Feb 05 13:28:25 <uhhimhere> i suspect rating
Feb 05 13:28:33 <uhhimhere> max draw
Feb 05 13:28:45 <uhhimhere> youd have to check USB spec
Feb 05 13:28:56 <Maxdamantus> Yes, but there's the current that's actually drawn and the current the device has asked to draw.
Feb 05 13:29:15 <Maxdamantus> A device is only meant to draw something like 100 mA until it asks the host if it can use more.
Feb 05 13:29:44 <Maxdamantus> otherwise it's just not complying to the specification, though I don't think hosts usually care.
Feb 05 13:29:56 <uhhimhere> i suspect its a case of whats your max need
Feb 05 13:30:34 <uhhimhere> i dont care bout whats in between; if i can handle it youre in else you shouldnt be on usb
Feb 05 13:30:43 <uhhimhere> kinda thing?
Feb 05 13:31:34 <Maxdamantus> I think it can negotiate.
Feb 05 13:32:20 <Maxdamantus> So a device might ask what the most it can draw is.
Feb 05 13:34:04 <Maxdamantus> It's kind of well-known to N900 users because N900s won't normally charge unless either the data pins are shorted (indicating a dumb power source), or it asks a host if it can draw more power.
Feb 05 13:34:34 <Maxdamantus> and lots of car chargers, etc won't do either.
Feb 05 13:35:03 <Maxdamantus> so you have to short the pins on the charger or use a cable that does that.
Feb 05 13:35:21 <Maxdamantus> most phones don't care and will draw the current they want to anyway.

Feb 05 13:58:29 <pluizer> My N900 cannot find any wifi-networks anymore, I tried reflashing it to no avail, is this a known issue?
Feb 05 14:00:22 <teotwaki> never heard of that one
Feb 05 14:01:12 <teotwaki> pluizer: any chance you could run iwlist scanning?
Feb 05 14:03:37 <pluizer> teotwaki: yes one moment though I'll have to install wirelesstools without internet.
Feb 05 14:03:51 <kerio> pluizer: does bluetooth work?
Feb 05 14:04:27 <Maxdamantus> pluizer: try `ifconfig -
Feb 05 14:04:29 <Maxdamantus> a`
Feb 05 14:04:50 <Maxdamantus> (without the newline)
Feb 05 14:05:10 <Maxdamantus> (ifconfig should be part of busybox)
Feb 05 14:05:54 <pluizer> kerio: It might but I have no bluetooth on my pc
Feb 05 14:06:07 <pluizer> Maxdamantus: ifconfig works, it does find wlan0
Feb 05 14:06:22 <Maxdamantus> pluizer: with the -a?
Feb 05 14:06:34 <pluizer> yes
Feb 05 14:06:41 <teotwaki> obviously with the -a, it's not up :)
Feb 05 14:07:08 <Maxdamantus> er, sorry, thought you said doesn't.
Feb 05 14:07:56 <pluizer> I'll have to install rootsh too I think, one moment
Feb 05 14:09:05 <kerio> don't you have ssh?
Feb 05 14:09:24 <pluizer> yes but no internet :)
Feb 05 14:09:25 <kerio> the default openssh package prompts you to add a root password
Feb 05 14:09:27 <kerio> so?
Feb 05 14:09:29 <kerio> ssh root@localhost
Feb 05 14:09:37 <pluizer> oh I;ll try
Feb 05 14:10:07 <Maxdamantus> g_ether might be useful.
Feb 05 14:12:18 <pluizer> ifconfig wlan0 up ; iwlist wlan0 scanning --> no results
Feb 05 14:12:56 <Maxdamantus> What about wmaster0?
Feb 05 14:13:42 <pluizer> wmaster0: Interface doesn't support scanning
Feb 05 14:13:53 <Maxdamantus> But does it show as up?
Feb 05 14:14:14 <pluizer> yes
Feb 05 14:14:36 <Maxdamantus> Does `dmesg` show anything interesting?
Feb 05 14:15:24 <pluizer> I'll have a look
Feb 05 14:20:33 <pluizer> Maxdamantus: I can see nothing special: http://pastebin.com/raw.php?i=LbFgziur
Feb 05 14:23:48 <Maxdamantus> pluizer: maybe you should try to see what happens if you connect anyway.
Feb 05 14:24:05 * Maxdamantus has only done that with wpa_supplicant.
Feb 05 14:24:27 <pluizer> I'll try that, thanks for helping btw
Feb 05 14:37:46 <pluizer> no luck, though now I think of it I flashed the fiasco image, maybe I should try the emmc.
Feb 05 14:39:29 <pluizer> does anybody know where to find it though? 
Feb 05 14:41:18 <Maxdamantus> I don't think that would be useful.
Feb 05 14:41:32 <pluizer> oh
Feb 05 14:41:34 <teotwaki> it could, actually
Feb 05 14:41:39 <pluizer> oh :)
Feb 05 14:41:48 <teotwaki> there's a post on tmo that says flashing the emmc fixed the same issue
Feb 05 14:42:27 <teotwaki> actually, the other way around

Feb 05 14:45:49 <teotwaki> warfare: google
Feb 05 14:45:56 <teotwaki> warfare: that's what I got when I googled around

Feb 05 14:47:12 <warfare> teotwaki: Ok, that's a google issue then :) 
Feb 05 15:05:21 <pluizer> Maxdamantus: indeed flashing emmc did not resolve the issue
Feb 05 15:25:05 <teotwaki> pluizer: have you checked the antenna?
Feb 05 15:25:19 <teotwaki> pluizer: sometimes it can get slightly disconnected (fairly rare, I'll admit), but it could be that
Feb 05 21:53:04 <pluizer> teotwaki: It must be the antenna, If I put my phone againt the wifi hotspot it does work. Thanks
Feb 05 22:29:54 <sixwheeledbeast> cleaning the contacts on the antenna can help.
