| 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. |
| 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. |
| 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. |
| 05:56.25 | Maxdamantus | and shorting the data pins on it causes it to do it for other devices too. |
| 05:56.35 | Maxdamantus | Hm. |
| 06:01.03 | Maxdamantus | Actually, that last bit isn't true. |
| 06:01.33 | Maxdamantus | Meh, maybe it is. |

| 06:48.46 | Maxdamantus | Maybe because the bits from the edge of my etching manage to make contact. |
| 06:53.21 | uhhimhere | hey guys what would be the criteria to be able to run maemo on a default android device? |
| 06:54.05 | Maxdamantus | uhhimhere: It's not going to. |
| 06:54.36 | uhhimhere | how come |
| 06:54.43 | uhhimhere | theyre both arm based |
| 06:54.56 | uhhimhere | and run on linux |
| 06:55.33 | Luke-Jr | Neither Maemo nor Android run on vanilla Linux |
| 06:56.07 | uhhimhere | so maemo cant use the lates kernel |
| 06:56.19 | Luke-Jr | also, Maemo is dead |
| 06:56.25 | Luke-Jr | for years now |
| 06:56.39 | Maxdamantus | afaik the standard Hildon binaries won't run without the particular OMAP graphics chip. |
| 06:57.11 | uhhimhere | Luke-Jr: there are more people in this room than say #sgs5 |
| 06:57.37 | uhhimhere | Luke-Jr: or sailfish |
| 06:58.11 | uhhimhere | Luke-Jr: in fact the one that comes closest is ubuntu-touch |
| 06:58.17 | uhhimhere | so it cant be that dead |
| 06:58.19 | freemangordon | Luke-Jr: hmm, my n900 doesn't show signs of being dead :) |
| 06:58.20 | Luke-Jr | maybe because there's no alternative to Maemo yet? |
| 06:58.34 | freemangordon | most probably |
| 06:58.42 | Luke-Jr | uhhimhere: also keep in mind Maemo is closed source, so an active community can't really maintain it |
| 06:59.10 | freemangordon | Luke-Jr: there were some developments on those closed bits recently |
| 06:59.15 | Luke-Jr | oh? |
| 06:59.29 | freemangordon | you know we have mce? |
| 06:59.37 | Luke-Jr | I thought Nokia had washed its hands of Maemo entirely |
| 06:59.40 | Luke-Jr | mce? |

| 07:04.12 | freemangordon | Luke-Jr: sure, there are more to go, but they can be REed on as-needed basis |
| 07:04.43 | freemangordon | as happened with https://gitorious.org/community-ssu/nokiamaps-navigation-provider/source/5142e28be6e3c61ae962ca282c94890c33a3f7be: for example |
| 07:04.56 | uhhimhere | freemangordon: i thought maemo 5 was community maintained and the source was open |
| 07:05.47 | freemangordon | uhhimhere: yes, it is community maintained, but lots of stuff, esp on the UI side is closed |
| 07:06.19 | uhhimhere | heh |
| 07:06.27 | uhhimhere | whatbout mer? |
| 07:06.55 | freemangordon | what about it? last time I tried Nemo on n900 it was as fast as a snail |
| 07:07.28 | Luke-Jr | lol |
| 07:07.38 | freemangordon | I don;t even think they support N900 recently |
| 07:12.28 | uhhimhere | freemangordon: is that nemo-mobile that you tried |
| 07:13.22 | freemangordon | I guess, there is (or was) an image for N900 floating around the inet |
| 07:17.51 | uhhimhere | how does the n950 compare w/ the n900 |
| 07:17.55 | uhhimhere | thoughts? |
| 07:18.40 | freemangordon | it does not :) |
| 07:18.53 | freemangordon | both HW and SW wise |
| 07:19.33 | freemangordon | the only thing n950 is better than N900 is the design - this thing looks great |
| 07:19.59 | uhhimhere | can it run maemo 5 |
| 07:20.05 | freemangordon | afaik no |
| 07:20.10 | freemangordon | well, it can |
| 07:20.24 | freemangordon | but I am not aware of anyone trying it |
| 07:20.36 | freemangordon | it just makes no sense |
| 07:21.08 | freemangordon | no FMTX, lack of storage, capacitive screen, bad radios, bad screen, ets |
| 07:21.15 | freemangordon | *etc |
| 07:21.40 | uhhimhere | but it looks great XD |
| 07:21.47 | freemangordon | yeah, looks great |
| 07:22.04 | Maxdamantus | Yay. I think I've got it to work. |
| 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? |
| 07:23.03 | Maxdamantus | though if I touch the current break in the PCB path it panics again. |
| 07:23.13 | Maxdamantus | will probably just put hot glue on it. |
| 07:25.14 | uhhimhere | Maxdamantus, what are you doing |
| 07:26.09 | Maxdamantus | Getting some charger thing to work properly. |
| 07:38.42 | Maxdamantus | wonders if it heated up before he started messing with it. |
| 07:41.01 | uhhimhere | Maxdamantus: would you be able to identify a serial line on a PCB if you saw one? |
| 07:41.15 | uhhimhere | im trying to think of where to tap in for console access on a pcb |
| 07:41.28 | Maxdamantus | No. |
| 07:41.31 | freemangordon | uhhimhere: what device? |
| 07:41.55 | uhhimhere | GT-S7580 |
| 07:41.59 | uhhimhere | SAMSUNG |
| 07:42.06 | freemangordon | oh |
| 07:42.22 | uhhimhere | does Imgur not accept .svg? |
| 07:43.18 | Maxdamantus | I wouldn't imagine so. |
| 07:43.31 | Maxdamantus | SVGs can have code in them. |
| 07:50.16 | Wizzup | and very painful recursion |
| 07:53.36 | uhhimhere | could you run ubuntu touch on the n900 |
| 07:53.50 | Wizzup | Luke-Jr: the n900 has quite some features working on mainline though |
| 07:53.54 | Wizzup | (kernel) |
| 07:54.25 | uhhimhere | so are the neo900 guys coming up with a new OS or are they sticking with maemo5 |
| 07:54.35 | Wizzup | the bring you the hw |
| 07:54.44 | Wizzup | not so much a full usable env |
| 07:54.59 | Wizzup | but I think FPT (?) was aiming for maemo |

| 10:52.35 | bencoh | what did you do to it ? |
| 10:52.55 | Maxdamantus | I plugged it into something without testing its voltage. |
| 10:53.12 | Maxdamantus | Though I tried plugging some cheaper devices in beforehand and they didn't complain. |
| 10:53.39 | Maxdamantus | will try to figure out how to use this multimeter. |
| 10:55.35 | uhhimhere | Maxdamantus, set to auto |
| 10:57.14 | Maxdamantus | I think I've figured it out. |
| 10:57.29 | Pali | echo reset > mode |
| 10:57.31 | Maxdamantus | I put it onto the 200 thing in the V-... section |
| 10:57.52 | bencoh | hmm |
| 10:58.16 | Maxdamantus | Seems to be 7.6 V. |
| 10:58.25 | Pali | reset will clear that overvoltage flag and reset kernel driver to charge again |
| 10:58.29 | Maxdamantus | though I'm obviously not very good at this. |
| 10:58.42 | Maxdamantus | It is charging again, but I rebooted it. |
| 10:58.42 | bencoh | oh btw, is nokia bme supposed to shutdown device when it thinks battery is at 0mAh ? |
| 10:58.51 | Maxdamantus | because it seemed to freeze the screen. |
| 10:58.55 | bencoh | or does it wait for a certain voltage/flag ? |
| 10:59.10 | bencoh | (bme fucked up my calibration yesterday night) |
| 10:59.16 | Pali | bencoh, nokia bme monitor only voltage and current |
| 10:59.20 | Pali | nothing more |
| 10:59.37 | Pali | and from these two data it calculate (somehow) percentage of battery |
| 10:59.43 | Pali | and also mAh |
| 10:59.45 | Maxdamantus | should've done electronics in high school. |
| 10:59.50 | bencoh | which means that their formula is off for this battery I guess |
| 11:00.06 | Pali | nokia bme is toxic |
| 11:00.13 | bencoh | haha, yeah |
| 11:00.15 | Pali | it store state infomation to CAL |
| 11:00.32 | bencoh | well I'm willing to ditch it but I still need to calibrate first |
| 11:00.38 | bencoh | oh, and ... one thing that bothers me |
| 11:00.41 | Pali | so it can "remember" some data used for guessing mAh |
| 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 |
| 11:01.41 | Pali | yes, then you will use data from bq27200 chip |
| 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 |
| 11:02.15 | Pali | yes |
| 11:02.39 | bencoh | does bq27200 stores its state somewhere ? |
| 11:02.46 | Pali | yes, in chip |
| 11:02.51 | bencoh | ram ? |
| 11:02.55 | bencoh | or nvram ? |
| 11:03.11 | Pali | do not remember |
| 11:03.21 | Pali | but n900 has backup battery |
| 11:03.23 | bencoh | I'll have to reread the ti spec |
| 11:03.36 | Maxdamantus | Does anyone's backup battery still work? |
| 11:03.39 | bencoh | hmm, does your backup battery work ? :D |
| 11:03.41 | Pali | and that is used in case when you remove big bl5j bayttery |
| 11:03.51 | Pali | my is probably dead now :-) |
| 11:03.54 | Pali | need to replace it |
| 11:03.58 | bencoh | same here ;) |
| 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)? |
| 11:04.55 | Maxdamantus | guesses he hasn't taken his battery out since using bme-replacement. |
| 11:05.24 | Maxdamantus | for more than the second or so I'm able to. |

| 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)." |

| 11:56.05 | kerio | that's like the whole point of the neo900, yes :) |
| 11:56.47 | antranigv | but neo900's hardware is not that new. like, camera, or screen |
| 11:57.01 | antranigv | just cz they are using N900s case of corse |

| 12:26.03 | Maxdamantus | I don't like buying things. |
| 12:26.59 | honestly | ¯\_(ã)_/¯ |
| 12:27.12 | Maxdamantus | I think my multimeter indicated that it allowed 0.33 A through it. |
| 12:27.30 | Maxdamantus | Though I don't really trust my newly-tested multimeter skills. |
| 12:28.00 | Maxdamantus | hasn't tried with a normal cable. |
| 12:30.14 | kerio | Maxdamantus: USB mandates 0.5A |
| 12:31.32 | Maxdamantus | I'm pretty sure the device it came with doesn't care what USB mandates. |
| 12:32.28 | Maxdamantus | Since it originally didn't charge my N900 with a normal USB cable. |
| 12:32.40 | uhhimhere | Maxdamantus, couldnt you output the driver values |
| 12:32.59 | Maxdamantus | uhhimhere: hopefully. |
| 12:33.04 | Maxdamantus | but dunno where to look. |
| 12:33.13 | Maxdamantus | /sys/class/power_supply/bq24150a-0/charge_current seems to always be 550 |
| 12:33.21 | Maxdamantus | even when it's not plugged in. |
| 12:33.47 | Maxdamantus | that seems like the most sensible name for what I'm looking for. |
| 12:34.27 | Maxdamantus | Maybe that's meant to be configurable. |
| 12:34.42 | Maxdamantus | so maybe if I write 330 into it I'll be able to use the charger with a normal cable. |
| 12:35.05 | Maxdamantus | Doesn't seem to be. |

| 12:43.18 | uhhimhere | i think your best best really is your multimeter |
| 12:43.34 | uhhimhere | its an "unbiased opinion" |
| 12:43.48 | uhhimhere | heres a stupid question...did you break the circuit |
| 12:44.21 | uhhimhere | to measure the current |
| 12:44.35 | uhhimhere | you gotta measure current in series.... |
| 12:46.08 | Maxdamantus | I didn't have anything actually running on it. |
| 12:46.29 | uhhimhere | yeah you gotta have something running first |
| 12:46.45 | Maxdamantus | I suspect that's what the two different contacts on the multimeter are for. |
| 12:46.55 | honestly | ... |
| 12:47.07 | honestly | ...no? |
| 12:47.10 | uhhimhere | im sorry back up |
| 12:47.20 | uhhimhere | did you have a load on the usb port? |
| 12:47.42 | Maxdamantus | No. Just a multimeter, with the USB connected to the "10ADC" pin. |
| 12:47.49 | uhhimhere | lol |
| 12:47.53 | uhhimhere | ok |
| 12:48.05 | Maxdamantus | as opposed to the "VΩMA" pin. |
| 12:48.21 | uhhimhere | nananana |
| 12:48.43 | honestly | this kills the usb |
| 12:48.45 | uhhimhere | you gotta load it and then put it into A(amps) |
| 12:48.52 | honestly | well, it shouldn't |
| 12:49.11 | honestly | but really putting a multimeter inside a usb circuit isn't easy |
| 12:49.24 | honestly | get a usb charger doctor |
| 12:49.28 | uhhimhere | it is you just gotta cut up a a USB cable |
| 12:49.37 | Maxdamantus | I think I've shortcircuited my USB before and restarted it by reloading *hci_core |
| 12:49.55 | Maxdamantus | er, *hci_hcd |
| 12:50.26 | uhhimhere | ok so let me get this straight |
| 12:50.46 | uhhimhere | your trying to measure the USB output power by hooking it up to a meter directly? |
| 12:51.20 | Maxdamantus | Kind of. |
| 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 |
| 12:51.36 | uhhimhere | you need to load it |
| 12:51.38 | honestly | uhhimhere: no. |
| 12:51.52 | Maxdamantus | uhhimhere: I think it depends what contact you're using. |
| 12:51.52 | uhhimhere | orly? |
| 12:52.04 | Maxdamantus | I think one of them draws as much current as it can (up to 10A) |
| 12:52.10 | honestly | when you put a multimeter into current measure mode it has close to zero impedance. |
| 12:52.12 | Maxdamantus | and the other draws as little as possible. |
| 12:52.16 | honestly | Maxdamantus: no. |
| 12:52.51 | honestly | Maxdamantus: the only difference between the high-amperage and low-amperage terminals, when in current measure mode, is the fuse. |
| 12:53.17 | Maxdamantus | Ah. |
| 12:54.39 | honestly | a multimeter in current measure mode is a dead short. |
| 12:55.56 | Maxdamantus | Ah right, my driver indicated that. |
| 12:56.03 | Maxdamantus | [2601747.694160] hub 1-1:1.0: over-current condition on port 1 |
| 12:56.34 | Maxdamantus | So why did my multimeter just say 0.33? |
| 12:56.54 | honestly | who knows? |
| 12:57.11 | honestly | i don't know how the circuitry in the usb port is laid out |
| 12:57.35 | Maxdamantus | Maybe my USB chip limits it to that when it notices the "over-current condition" |
| 12:58.31 | Maxdamantus | I imagine USB should be expected to be resilient to shortages on modern motherboards. |
| 12:59.48 | uhhimhere | Maxdamantus, yeah well in anycase again electricity 101. you wanna measure current. You break the circuit. Or use a clamp |
| 12:59.53 | uhhimhere | hall effect etc |
| 13:00.07 | uhhimhere | load it with something that its meant to drive |
| 13:00.22 | uhhimhere | and break the circuit with the meter or clamp it |
| 13:00.35 | Maxdamantus | Would have to find more USB cables to take apart. |
| 13:01.36 | Maxdamantus | is using rolled-up aluminium foil to connect things to the terminals on his multimeter. |
| 13:01.45 | honestly | the usb limits current anyway if there is no enumeration |
| 13:02.21 | uhhimhere | why do you wanna know anyways? |
| 13:03.17 | honestly | i.e. there's no proper usb device connected |
| 13:04.41 | Maxdamantus | I want to know what's special about the USB cable that came with some Chinese solar power charger thing. |
| 13:05.12 | uhhimhere | its made in china? |
| 13:05.20 | Maxdamantus | Yes. |
| 13:05.27 | uhhimhere | thats special enough? |
| 13:06.09 | honestly | Maxdamantus: so just measure the resistance of the cable? |
| 13:06.48 | Maxdamantus | Yeah, I can probably do that with some more aluminium foil and cardboard. |
| 13:06.59 | uhhimhere | TF |
| 13:07.01 | uhhimhere | lol |

| 13:12.32 | uhhimhere | Maxdamantus, http://www.mjmwired.net/kernel/Documentation/usb/power-management.txt#509 |
| 13:12.35 | uhhimhere | interesting |
| 13:14.00 | Maxdamantus | Indeed. |
| 13:26.56 | uhhimhere | Maxdamantus, : http://yosemitefoothills.com/Electronics/USBProgrammingSummary.html |
| 13:27.05 | uhhimhere | The hub controller detects the device, reads its USB descriptors, and makes sure it doesn't demand too much power. |
| 13:27.37 | uhhimhere | well there ya go |
| 13:28.05 | Maxdamantus | "demand" as in "ask for"? |
| 13:28.12 | Maxdamantus | or "use" |
| 13:28.18 | Maxdamantus | I suspect it means ask for. |
| 13:28.25 | uhhimhere | i suspect rating |
| 13:28.33 | uhhimhere | max draw |
| 13:28.45 | uhhimhere | youd have to check USB spec |
| 13:28.56 | Maxdamantus | Yes, but there's the current that's actually drawn and the current the device has asked to draw. |
| 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. |
| 13:29.44 | Maxdamantus | otherwise it's just not complying to the specification, though I don't think hosts usually care. |
| 13:29.56 | uhhimhere | i suspect its a case of whats your max need |
| 13:30.34 | uhhimhere | i dont care bout whats in between; if i can handle it youre in else you shouldnt be on usb |
| 13:30.43 | uhhimhere | kinda thing? |
| 13:31.34 | Maxdamantus | I think it can negotiate. |
| 13:32.20 | Maxdamantus | So a device might ask what the most it can draw is. |
| 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. |
| 13:34.34 | Maxdamantus | and lots of car chargers, etc won't do either. |
| 13:35.03 | Maxdamantus | so you have to short the pins on the charger or use a cable that does that. |
| 13:35.21 | Maxdamantus | most phones don't care and will draw the current they want to anyway. |
