[0:00] <Nine_9> it's going to be ugly to have two supplies though
[0:00] <Nine_9> well, sure I could use a single supply, but I don't want to disassemble the one i'm using for the pi
[0:01] <Nine_9> perhaps I could make an y adaptor
[0:01] <[Saint]> Aha, sorry, my mistake, its 1.2A, not 2.1A
[0:02] <[Saint]> add/change max_usb_current=1
[0:02] <Nine_9> don't want to burn my disc though... is it safe to just connect it directly to something like a USB charger?
[0:02] <Nine_9> [Saint]: in config file?
[0:02] <[Saint]> the drive has its own current limiting, and, yes.
[0:02] <Milenko> O_o
[0:02] <Nine_9> [Saint]: nice. thank you :)
[0:03] <Nine_9> what about usb flash drives?
[0:03] <[Saint]> None of them need more than 500mA
[0:04] * codestorm (~codestorm@cpe-75-83-205-183.socal.res.rr.com) has joined #raspberrypi
[0:04] * Tenkawa (~arakeen@unaffiliated/tenkawa) has joined #raspberrypi
[0:04] <Tenkawa> hey all
[0:04] * OffensiveUser (~Offensive@s5144500c.adsl.online.nl) Quit (Quit: Leaving)
[0:04] <[Saint]> You can also poke the "magic hidden GPIO pin" in software for current limiting via setting pin 38 high.
[0:04] * Almazys (~Almazys@ip-129.net-89-3-97.rev.numericable.fr) Quit (Quit: Good bye all ! :))
[0:04] * foob- (~dicklips@ Quit ()
[0:05] <[Saint]> That way, it won't survive a reset, so, better for testing I guess - but this is safe anyway.
[0:05] <codestorm> Sonny_Jim: thanks
[0:05] <Nine_9> [Saint]: nice. thanks
[0:05] * abnormal (~abnormal@252.sub-70-209-138.myvzw.com) has joined #raspberrypi
[0:06] <codestorm> I'm not sure how complicated it'll get, probably not very. Just fetching images, maybe some text, at most a fade animation
[0:06] <Sonny_Jim> I would look into using SDL2
[0:06] <Sonny_Jim> Lots of tutorials and it's easy enough to use
[0:06] * perkan (~neosmo@ Quit (Quit: Leaving)
[0:06] <Sonny_Jim> Although you'll have to compile SDL2 as it's not in the Raspbian repository yet, only SDL1
[0:06] <Nine_9> in fact i'm going to use another 2 usb devices, (flash drive and logitech nano wireless receiver) so I think i'm not even going to try hacking the power stuff in my pi, i'm just going to make an external supply for the HDD
[0:06] <[Saint]> in wiringpi, you could so (someone please correct my syntax - its been a while): gpio -g write 38 0; gpio -g mode 38 out; gpio -g write 38 1
[0:07] <Nine_9> thank you for the help nonetheless. really appreciated.
[0:07] <[Saint]> (that might seem weird but I'm making sure the pin is set low first, then output mode, then pulling it high)
[0:07] <[Saint]> but for your purposes, I would think it better to use the config.txt method.
[0:07] <codestorm> Sonny_Jim: I'll google it
[0:08] * esas (~esas@unaffiliated/esas) has joined #raspberrypi
[0:08] * killer_prince (~killer_pr@ has joined #raspberrypi
[0:08] <Sonny_Jim> Actually, it depends on what languages you know
[0:08] * killer_prince is now known as lazy_prince
[0:08] <Sonny_Jim> If it's your first attempt at coding, maybe Python would be a better choiec
[0:08] <Sonny_Jim> as SDL2 is C/C++
[0:09] * jimvideo (~jimvideo@184-12-233-85.dr01.brny.ca.frontiernet.net) has joined #raspberrypi
[0:10] <Nine_9> [Saint]: well, the HDD is rated 850mA, no idea on the nano receiver and flash drive
[0:10] <Nine_9> too much, although i really doubt there's a real risk of damage
[0:10] * utack (~utack@ip9234cb8c.dynamic.kabel-deutschland.de) Quit (Remote host closed the connection)
[0:11] <codestorm> I'm an experienced coder. I was actually considering trying to do it in the Elixir language, but i just don't know how to do things graphically on linux/RPi
[0:11] * utack (~utack@ip9234cb8c.dynamic.kabel-deutschland.de) has joined #raspberrypi
[0:11] <Nine_9> I mean, what could happen? I only see unjustifiable paranoia on the net.
[0:12] * utack (~utack@ip9234cb8c.dynamic.kabel-deutschland.de) Quit (Remote host closed the connection)
[0:12] <Sonny_Jim> Ah then I would suggest SDL2, as it's portable between Android/Apple/PC/ARM etc
[0:12] <[Saint]> Nine_9: its best to assume that both will be consuming the full allocation, so, 500mA, or 1A for both. Putting you at almost 2A of draw.
[0:12] <[Saint]> Which is...a lot.
[0:12] <Nine_9> yeah
[0:12] * utack (~utack@ip9234cb8c.dynamic.kabel-deutschland.de) has joined #raspberrypi
[0:12] * lazy_prince (~killer_pr@ Quit (Ping timeout: 245 seconds)
[0:13] <codestorm> just wondering - how would you do it in Python?
[0:13] <Nine_9> the flash drive is rated 100mA though
[0:13] <[Saint]> Its probable that the only way you're going to power that HDD with the pi is via a Y-cable (do you know what that is?).
[0:13] <Sonny_Jim> Dunno, I've never coded in python. Seems a popular language for the Pi though
[0:13] <[Saint]> EVen then, its not leaving much room for anything else.
[0:13] <codestorm> ah ok
[0:13] <[Saint]> You'd have to pick between the wifi and the flash drive.
[0:14] <Nine_9> [Saint]: like, connecting 2 ports on a single device?
[0:14] <[Saint]> correct.
[0:14] <Nine_9> but, will that make any difference, i mean, are they independent?
[0:14] <[Saint]> One cable just had power lines, the ohter power+data.
[0:14] <Nine_9> yeah, i understand
[0:14] <[Saint]> *other
[0:15] <Nine_9> will that work though?
[0:15] * killer_prince (~killer_pr@ has joined #raspberrypi
[0:15] <[Saint]> Yes.
[0:16] <[Saint]> But it is infinitely better for you to use a dedicated powered hub.
[0:16] <ozzzy> hehe... just got the pi2 and 320G usb drive talking
[0:18] <ozzzy> awesome
[0:19] <Nine_9> [Saint]: I don't have any externally powered usb hub around, so I think it's best to just connect the flash and nano transmitter directly to the pi and wire an adaptor for the HDD that way I don't need to shop for stuff
[0:19] <Nine_9> I have a bunch of 1mA usb supplies around
[0:19] <Nine_9> i think they're safe for the HDD
[0:20] * Macuser (~textual@unaffiliated/macuser) Quit (Quit: My MacBook Pro has gone to sleep. ZZZzzz…)
[0:20] * killer_prince (~killer_pr@ Quit (Ping timeout: 264 seconds)
[0:20] <Nine_9> in fact nope, I'm going to connect the same supply used on the Pi as it's rated 5mA
[0:20] <Nine_9> 5A
[0:20] <ozzzy> I have a 2A supply from my Nexus7 that I use
[0:21] <[Saint]> You almost certainly will not be able to connect all these peripherals at once.
[0:21] <[Saint]> But, you can try.
[0:21] <ozzzy> now to get ntfs working
[0:21] * Moshin (~bangboom@udp000088uds.hawaiiantel.net) has joined #raspberrypi
[0:21] <Tenkawa> ozzzy: got my rpis finally
[0:21] <Tenkawa> all online
[0:22] * killer_prince (~killer_pr@ has joined #raspberrypi
[0:22] * [Saint] wonders how many people rushed out to get the rpi2 only to discover the ODROID C1 and then felt like kicking themselves in the bum.
[0:22] <[Saint]> I imagine "a lot".
[0:23] <McBride36> rpi has a better community behind it htough
[0:23] <McBride36> well...bigger
[0:23] <[Saint]> I mean, the raspi 2 is cool and all, but, to put it in a somewhat amusing analogy - "its like putting lipstick on a pig"
[0:24] <Tenkawa> either box really depends on what you are willing to put into it
[0:24] <[Saint]> Community becomes somewhat irrelevant once you're able to run a common distro straight out of the box.
[0:24] <[Saint]> I mean, debian and Android both have communities that outshine the raspi by orders of magnitude.
[0:24] <[Saint]> raspi's need for a community came about mostly due to the weird nature of the distribution.
[0:25] <Peio> what's so much better with the C1 [Saint]?
[0:25] <[Saint]> But, I digress.
[0:26] <Tenkawa> I might get a few C1's too however I'm quite happy with the rpis so far
[0:26] * killer_prince (~killer_pr@ Quit (Ping timeout: 244 seconds)
[0:26] <[Saint]> Peio: ask Google. Primarily, USh-I sdcard (a lot faster), optional eMMC module ( waaaaaaaaaaaaaaaay faster), gigabit ethernet, and - running Android.
[0:26] <[Saint]> *UHS-I
[0:27] * Macuser (~textual@unaffiliated/macuser) has joined #raspberrypi
[0:27] * Macuser (~textual@unaffiliated/macuser) Quit (Max SendQ exceeded)
[0:27] <Peio> thing is with a pi you're sure there will still be support 3y from now
[0:28] <[Saint]> In fact, I have a very early mostly working 5.0.2 Android image booting on it presently, but its not ready for the light of day just yet - too many nasty hacks and development related security holes for prime-time just yet.
[0:28] <[Saint]> Peio: the same is true with Debian and Android.
[0:28] * ctorp (~ctorp@ool-182cfb1c.dyn.optonline.net) Quit ()
[0:28] <[Saint]> Neither of those are going anywhere
[0:29] <Triffid_Hunter> [Saint]: I doubt that a UHS-1 card would be any faster than a class 2 or class 4 for random 4k write
[0:30] <[Saint]> And in a world where people are only doing random writes, I would agree with you.
[0:30] <Tenkawa> cheers all.. bbl
[0:30] <Peio> is there a debian for it ? all I see is ubuntu
[0:30] * Tenkawa (~arakeen@unaffiliated/tenkawa) Quit (Quit: leaving)
[0:30] <[Saint]> However, this is the real world, where contiguous reads and writes in large form are a fact of life.
[0:30] * Macuser (~textual@unaffiliated/macuser) has joined #raspberrypi
[0:30] <Peio> on a computer like that, not really
[0:30] <Peio> I never write big files to my sd
[0:31] * cybr1d (~cybr1d@unaffiliated/cybr1d) Quit (Ping timeout: 265 seconds)
[0:31] <[Saint]> You can trivially spin up a debian image for this, and Ubuntu is just Debian with an ugly skin on it, really. That's my point. Ubuntu needs Debian to exist in turn.
[0:31] <Peio> apparently ubuntu depends hardkernel's dev for the kernel
[0:32] <Peio> I wouldn't trust support 3y from now
[0:32] * thescatman_ (~thescatma@unaffiliated/thescatman) Quit (Ping timeout: 246 seconds)
[0:32] <Peio> from a company that will probably have newer products they'll want to push
[0:32] <Peio> gigabit ethernet is cool though
[0:33] * OffensiveUser (~Offensive@5ED3D4A2.cm-7-4d.dynamic.ziggo.nl) has joined #raspberrypi
[0:34] <[Saint]> The not bat-crap insane GPU running the show is also very cool.
[0:34] <[Saint]> But a lot of people don't seem to care about that, which sucks.
[0:35] <Nine_9> what's wrong with the gpu?
[0:35] <[Saint]> Errr, that's worded weirdly. "The GPU isn't bat-crap insane, and its not running the show, and that's also very cool."
[0:35] <[Saint]> - much better.
[0:35] <Nine_9> oh, ok :)
[0:36] <[Saint]> I hope one day Broadcom gives up the keys to the kindom, as it were, but I sincerely doubt it'll happen.

[0:49] <Nine_9> ozzzy: config hack?
[0:50] <[Saint]> Not necessarily.
[0:51] <[Saint]> Some external drives are happy to run from ~500mA (or less).
[0:51] <ozzzy> max_usb_power=1
[0:51] <ozzzy> wouldn't run before the config.txt change
[0:51] <[Saint]> Well, looks like I killed two birds with one stone today then huh? ;)

[0:54] <Nine_9> still not convinced my samsung hdd is going to work :P. ozzzy what is that HDD rated and what are the other stuff connected to the other USB ports?
[0:55] <Nine_9> i see something like a wifi adapter and a usb flash drive
[0:55] <ozzzy> who knows what it's rated at... it's an older usb2 drive and that's a wifi adapter running next to it
[0:55] * SiC (Simon@cpc12-aztw24-2-0-cust193.aztw.cable.virginm.net) Quit (Remote host closed the connection)
[0:55] <ozzzy> the flash drive isn't plugged in
[0:55] <Nine_9> hmmm... interesting... I'm pretty sure the wifi adapter is power hungry :)
[0:56] <ozzzy> probably
[0:56] <ozzzy> most are
[0:56] <ozzzy> with my b if I plugged anything in while it was running it would reset

[0:57] <Nine_9> is that the pi2?
[0:57] <Syliss> thats why i would use a usb power injector or hub

[0:59] <Syliss> doesnt matter, they all have issues with passing power down
[1:00] <ozzzy> well.. mounting the drive in /var/www/files appears to work
[1:00] <ozzzy> the little Pi might be a 1/2 decent web server
[1:00] <ozzzy> or file server
[1:01] <abnormal> or app server
[1:01] * DLSteve (~DLSteve@c-73-7-226-217.hsd1.ga.comcast.net) Quit (Quit: Leaving)
[1:01] <Syliss> just remember that the nic and usb share the same pipe so speeds slow down when using them

[1:41] <teclo-> hi I've read this http://www.raspberrypi.org/web-browser-released/ ... I suppose that I need to upgrade to Debian jessie before doing aptitude install epiphany-browser ?
[1:41] <ozzzy> I dumped epiphany and installed chromium
[1:42] <teclo-> ah
[1:42] <teclo-> isn't chromium too slow on a Pi ?
[1:42] <[Saint]> vastly
[1:42] <[Saint]> anhoo - you can always check.
[1:42] <[Saint]> 'apt-cache search epiphany-browser'
[1:42] <ozzzy> it works
[1:43] <geosmin> i'm thinking of compiling a kernel on the pi...
[1:43] <geosmin> how long could that take
[1:43] <acidjazz> 16 weeks
[1:43] * dj_pi (~dj@c-107-5-228-80.hsd1.mi.comcast.net) has joined #raspberrypi
[1:44] <geosmin> could i compile it on an x86_64 machine?
[1:44] <[Saint]> Nah, it'll only take 15 weeks, 6 days, 23 hours, and 59 minutes.
[1:44] <[Saint]> Geeez man, get it right.
[1:44] * ozzzy is used to Mosaic on a 286.... Chromium on a Pi is zippy
[1:45] <[Saint]> I believe you could do it in qemu.
[1:45] <[Saint]> but pure crosscompilation for the kernel is messy, and doesn't work out for a reason I've long since forgotten.
[1:46] <ozzzy> the Pi 2 is fast enough to start the compile at bedtime
[1:46] <geosmin> so it looks like kernel comp takes about 12h30m
[1:47] <quantumfoam> met a guy today who is looking at putting together and selling nicely packaged (like, would look good next to nice stereo equpiment) RPi-based game consoles
[1:47] <quantumfoam> for emulation
[1:47] <geosmin> meh
[1:47] <quantumfoam> why would compiling a kernel take that long?
[1:47] <quantumfoam> isn't there an ARM-optimized compiler?
[1:47] <geosmin> that'd be compiling on the pi itself
[1:48] <geosmin> is a 850 overclock unreasonable?
[1:48] <quantumfoam> might need a passive heatsink but yes
[1:48] <geosmin> i've got heatsinks, but i'mhoping to shave off.... some time
[1:48] <quantumfoam> you could compile it on the Pi
[1:48] <quantumfoam> I don't see why not
[1:48] * Tachyon` is now known as Tach[Zzz]
[1:48] * harish (~harish@ Quit (Ping timeout: 245 seconds)
[1:48] <geosmin> gonna go ahead and ask again
[1:48] <geosmin> i overclocked to 850
[1:48] <[Saint]> Oh God. No. Just....No.
[1:48] <quantumfoam> you would probably need to install some packages that are not on there by default
[1:48] <geosmin> shouldi be scapred?
[1:48] <[Saint]> Get that heat sync garbage right out of your head.
[1:49] <Triffid_Hunter> geosmin: I think setting up a cross compiler would take less time than compiling natively
[1:49] <quantumfoam> not that I can think of
[1:49] <quantumfoam> besides which
[1:49] <jonesinator> cross compiling ftw
[1:49] <geosmin> [Saint]: do tell
[1:49] <quantumfoam> why would you want to recompile it?
[1:49] <quantumfoam> a lot of work has already gone into it
[1:49] <quantumfoam> e.g. raspbian
[1:49] <[Saint]> There is _absolutely_ no need for a heat sync on the pi, at all, period.
[1:49] <keetrainchild> I compiled my kernel natively, but that was on a RPi2. I think it took an hour or two.
[1:49] <OffensiveUser> lol
[1:50] <quantumfoam> [Saint]: it isn't out of the question for a higher-clocked ARM-based processor to need cooling
[1:50] <keetrainchild> For the 1, it would probably take much longer, so like others said, cross-compiling is a good idea.
[1:50] <ozzzy> if I want to use my USB monitor I need a kernel recompile
[1:50] <[Saint]> It is, completely.
[1:50] <quantumfoam> no it isn't, it exists. in ARM-based server blades.
[1:50] <[Saint]> Its a chipset for embedded applications, it has its own thermal management.
[1:50] <Triffid_Hunter> quantumfoam: yeah, but the chip on the RPi is actually the ram, the CPU is sandwiched underneath it. putting a heatsink on the ram isn't going to help
[1:50] <[Saint]> It won;t even /start/ to care until it gets to 80C.
[1:50] <[Saint]> So...just...no.
[1:50] <quantumfoam> it would help some
[1:50] <keetrainchild> There are some instructions at http://wiki.gentoo.org/wiki/Raspberry_Pi .
[1:50] <[Saint]> No.
[1:51] <geosmin> [Saint]: well, okay. but i DID notice idle temp went from ~47 to ~37
[1:51] <quantumfoam> and yes it would help with overclocking because you could keep the chip from throttling itself
[1:51] <[Saint]> geosmin: that's nice, but, irrelevant.
[1:51] <geosmin> if it doesn't care below <80 that's moot, but it's still nice
[1:51] <quantumfoam> ...
[1:51] <quantumfoam> it is NOT irrelevant
[1:51] * OffensiveUser grabs popcorn
[1:51] <[Saint]> 10 degrees here makes precisely no difference whatsoever.
[1:51] <geosmin> it does if you're at 90 :)
[1:51] <[Saint]> You basically bought an irrelevant hunk of shiny metal.
[1:51] <quantumfoam> semiconductors perform better at lower temperatures, period. the difference may not be that big, but it is there.
[1:52] <quantumfoam> and it protects it from electromigration
[1:52] <geosmin> [Saint]: maybe, they were included with a 3$ case i bought from china. i'm not complaining
[1:52] <keetrainchild> Also, lower temperatures can prolong the life of the chip.
[1:52] <quantumfoam> yes
[1:52] <[Saint]> Oh my god...wow. Just...wow.
[1:52] <quantumfoam> what keetrainchild said
[1:52] <[Saint]> I've got a lovely tinfoil hat I can sell you too.
[1:52] <quantumfoam> are you an electrical engineer?
[1:53] <OffensiveUser> I got some silver speaker cables for u too
[1:53] <OffensiveUser> copper core silver plated usb cables
[1:53] <quantumfoam> there is quite a bit of hifi stuff that is wanking
[1:53] <[Saint]> I am a trade certified electrician, actually, yes.
[1:53] * ozzzy is a certified nut
[1:53] <quantumfoam> I would wager I've read just as much or more than you have, and I understand the physics as well.
[1:54] <[Saint]> But that's irrelevant. The pi does not need a heat sync, period, even if you're overclocking to insane values.
[1:54] <SirLagz> hai
[1:54] <ozzzy> those little heat sinks they give away are useless anyway
[1:54] <[Saint]> Indeed.
[1:54] <quantumfoam> the performance of microprocessors degrades at higher temperatures. well before their "cut off" point.
[1:54] <ali1234> it doesn't need a heatsink because it has a thermal cut out
[1:54] <geosmin> ozzzy: i wouldn't call -10C useless
[1:54] <OffensiveUser> i think they add to the aesthetic
[1:54] <ozzzy> yep... they look l33t
[1:54] <[Saint]> Let alone the fact that unless its a pi 2 you'd be putting it on the RAm package...
[1:55] <OffensiveUser> also provide peace of mind for the user
[1:55] <ozzzy> they didn't do a thing for my B
[1:55] <quantumfoam> open op a recent dual core ARM-based router
[1:55] <ali1234> because ram doesn't generate heat, right? everyone knows that...
[1:55] <quantumfoam> notice that there is a heatsink
[1:55] <[Saint]> ozzzy: right, because it would be sitting on the RAM, not the CPU.
[1:55] <geosmin> [Saint]: actually i've got 3! one on each chip
[1:55] <quantumfoam> heat is conducted through the entire package
[1:55] <quantumfoam> rather efficiently in fact
[1:55] * geosmin shovels popcorn into his mouth
[1:55] <[Saint]> Wow man. You're extra l337 then... ;)
[1:55] <quantumfoam> that's one of the main reasons they stacked them
[1:56] <geosmin> [Saint]: you''re saying if you had em lying around you'd chuck em in the garbage?
[1:56] <Triffid_Hunter> I thought they stacked them because they're designed to be stacked, and the CPU doesn't make much heat in the first place?
[1:56] <quantumfoam> anyway
[1:56] * ozzzy chucked them in the garbage
[1:56] <quantumfoam> geosmin: put a tiny bit of arctic silver compound on there
[1:56] <quantumfoam> passive heatsink
[1:56] <quantumfoam> you're good to go
[1:56] <[Saint]> It doesn't change the fact that it won;t even start to care about limiting until 80C, won't bother about thermal shutdown until 85C, and doesn't need a heat sync, at all, period. You should take a look at how hot your phone's CPU runs one day.
[1:57] <OffensiveUser> geosmin, if i got some i'd stick em on there for looks
[1:57] <ozzzy> now... my Atom cooks along at 80C all the time.... it's where it lives
[1:57] <[Saint]> Better add a heat sync there too eh hun?
[1:57] <ozzzy> sometimes 90
[1:57] <ozzzy> 90C with 100% load

[1:57] <[Saint]> right, the limits for the pi here are very conservative. Its rated much higher.
[1:57] <quantumfoam> my Edison has...GUESS WHAT. A HEATSINK.
[1:57] <[Saint]> It doesn't care at all.
[1:57] <OffensiveUser> well apple has a patent for fans in phones
[1:57] <quantumfoam> shared by all the parts, but still
[1:57] <ali1234> someone the other day tried to tell me phones don't have heat sinks in them
[1:57] <ali1234> i don't remember who it was
[1:57] <quantumfoam> and shit it's clocked lower than the Rpi
[1:58] <SirLagz> I'm pretty sure somewhere that Dom and James were talking about how the Pi operates better *without* a heatsink
[1:58] <SirLagz> I could be remembering wrong though
[1:58] <ali1234> SirLagz: i hope so because that make no sense
[1:58] <ali1234> at the very worst it will do absolutely nothing
[1:58] <[Saint]> Nice work trying to justify your irrelevant point of view hun, but...no. Sanity abounds in this place.
[1:58] <SirLagz> the chipset was designed to work at warm temperatures because it's designed for embedded applications.
[1:59] <ali1234> come off it
[1:59] <ali1234> that's BS
[1:59] <OffensiveUser> the leet looks of heatsinks makes the pi perform better
[1:59] * jlf (~user@pdpc/supporter/active/jlf) Quit (Read error: Connection reset by peer)
[1:59] <ali1234> apart from anything else, a heat sink will never get it below room temperature
[1:59] <ozzzy> and racing stripes make your car go faster
[2:00] <OffensiveUser> does anyone want to buy some silver usb cables for pi power supplies
[2:00] <[Saint]> ali1234: that's actually not true, many of the crappier heat syncs out there just add more mass, and as such, give it more ability to retain heat. SirLagz was quite correct.
[2:00] <OffensiveUser> the marginally lower impedance totally justifies the price I swear

[2:02] * cameronf_ (~cameronfr@ has joined #raspberrypi
[2:02] <SirLagz> the only situation where a *good* heatsink would actually be useful is if youre overvolting the CPU
[2:02] <SirLagz> if you're just loading the CPU up, you don't need a heatsink.
[2:02] * Moshin (~bangboom@udp000088uds.hawaiiantel.net) has joined #raspberrypi
[2:02] <[Saint]> adding more mass with a lower thermal coefficient is only going to make it retain more heat. By disallowing its ability to easily dissipate. That's common sense you're trying to argue right there.

[3:06] <ppq> no prepaid available?
[3:06] <SirLagz> ppq: the credit would expire every 30 days for the cheaper one, so no point

[3:07] <ali1234> three's 3-2-1 plan would be perfect for this
[3:08] <SirLagz> ppq: the ones that don't expire in 30 days, you're paying like $200 for credit to expire in a year, which if you don't use any, you've just wasted $200
[3:08] <ali1234> 2p/text and 1p/megabyte 4G, and no expiry on credit

[4:16] <MartyMacGyver> I have a question about the crosstool-NG linaro toolchain used to build the firmware.
[4:17] <MartyMacGyver> The stanard rpi update kernel has a version which tells me "gcc version 4.8.3 20140303 (prerelease) (crosstool-NG linaro-1.13.1+bzr2650 - Linaro GCC 2014.03)" was used to build it.
[4:18] <MartyMacGyver> When I build the same kernel using the tools in raspberrypi/tools, I get a version based on "gcc version 4.8.3 20140106 (prerelease) (crosstool-NG linaro-1.13.1-4.8-2014.01 - Linaro GCC 2013.11)"
[4:20] <MartyMacGyver> Why might that be? Note that I used the gcc-linaro-arm-linux-gnueabihf-raspbian toolchain to build (*not* the x64 version as it's not that way in the docs)

[8:57] <shiftplusone> MartyMacGyver, that sounds like like a statement
[8:58] <MartyMacGyver> A statement of pain and misery.
[8:59] <MartyMacGyver> I can cross-compile the RPi kernel and headers from source, create debs and install and run with them successfully...
[8:59] * ponA (Miranda@HSI-KBW-134-3-94-90.hsi14.kabel-badenwuerttemberg.de) has joined #raspberrypi
[8:59] <MartyMacGyver> but the scripts in /usr/src/linux-headers-3.18.7-v7+/scripts are all native to the host

[8:59] <MartyMacGyver> (except empty.o FWIW)
[8:59] * Tach[Zzz] is now known as Tachyon`
[9:00] <MartyMacGyver> A frustrating last mile to a day of work on this.
[9:01] * dreamon (~dreamon@unaffiliated/dreamon) Quit (Ping timeout: 256 seconds)
[9:01] <shiftplusone> MartyMacGyver, yup, sounds about right
[9:01] <MartyMacGyver> (because cross-compiling the kernel is rather arcane despite the smattering of docs on the subject)
[9:01] <shiftplusone> cross-compiling the kernel is straight forwards... it's the 'headers' in the debian sense of the term that's arcane.
[9:02] <MartyMacGyver> Building the kernel on the Pi (even the Pi 2) is prohibitive.
[9:02] <shiftplusone> no it isn't
[9:02] <shiftplusone> I have nightly builds set up on a pi 2 with ccace
[9:02] <MartyMacGyver> Yeah... it is, especially with an SD card and weird seg faults.
[9:02] <shiftplusone> *ccache
[9:03] <shiftplusone> compiles a pi 1 and a pi 2 kernels, headers and other packages in about an hour
[9:03] <MartyMacGyver> Hmm.
[9:03] <shiftplusone> I use an external HDD, not the sd card for it
[9:03] <shiftplusone> You can even add distcc in the mix
[9:03] <MartyMacGyver> Yeah, that probably helps, but an end user should be able to just install the header package and move along.
[9:04] <shiftplusone> MartyMacGyver, yes, that's why I started compiling them. They will eventually be official.
[9:04] <MartyMacGyver> so making it easy and fast to cross-compile is the next best thing when the goal is to compile a simple header-based object. Oh?
[9:04] <MartyMacGyver> Are you publishing?
[9:04] <shiftplusone> MartyMacGyver, not yet, but it will eventually be in the raspberrypi.org repo
[9:05] <MartyMacGyver> Well, that's good news then
[9:05] <shiftplusone> I'd like to set up a distcc cluster of pi 2s to speed things up a bit as well >.>
[9:06] * Syliss (~temp@c-24-23-6-50.hsd1.ca.comcast.net) has joined #raspberrypi
[9:06] <MartyMacGyver> That'd help I'm sure
[9:06] * r3dsm0k3_ (~r3dsm0k3@ has joined #raspberrypi
[9:06] <shiftplusone> I'm not convinced. If ccache only brings it down to an hour, the bottleneck is probably in the IO somewhere.
[9:07] <MartyMacGyver> Really, though, except for the scripts the cross compilation seems solid. And 20 minutes total from unbuilt source.
[9:07] <MartyMacGyver> (that's just with 2 cpus allocated to the VM)
[9:07] * r3dsm0k3 (~r3dsm0k3@ Quit (Ping timeout: 246 seconds)
[9:07] * r3dsm0k3_ is now known as r3dsm0k3
[9:08] <MartyMacGyver> And the kernel today is built that way... it's obvious from /proc/version
[9:09] <shiftplusone> I think it would maybe make sense to split things up a little differently. Compile athe armv7 and armv6 kernels on separate pis, then build the combined package. That should be quicker than distcc.
[9:09] <shiftplusone> *the
[9:09] <MartyMacGyver> True
[9:10] <shiftplusone> Ah well... as long as I have an excuse to set up a pi cluster, I'm happy.
[9:10] <MartyMacGyver> I'm a proponent of cross-compiling just because it'd be fast, before optimizations like ccache even.
[9:10] <shiftplusone> yes, but as you know, it contaminates the headers package.
[9:11] <MartyMacGyver> I'm not sure why that is though... technically it should be able to build a target toolset as well.
[9:11] <MartyMacGyver> FWIW - https://gist.github.com/MartyMacGyver/2ed99ec1e56d60c22519
[9:12] <shiftplusone> The way the build system works is that it builds some tools to compile the rest of the kernel. For example, menuconfig, device tree compiler and so on.
[9:12] <shiftplusone> So some things are native.
[9:12] <MartyMacGyver> Of course.... but I'd cross compile them too for distribution.
[9:12] <MartyMacGyver> This is not a new problem - I just wonder how others have solved it.
[9:13] <shiftplusone> That would be the sensible thing to do.
[9:13] <shiftplusone> Others seem to compile natively
[9:13] <MartyMacGyver> (some targets simply aren't appropriate to compiling natively)
[9:14] <MartyMacGyver> Anyway, that's where I'm stuck. If I managed to get cross compiling to work fully it'd be useful, but if we get header drops with each kernel binary drop that'll work too.
[9:14] <shiftplusone> If you figure something out, please do let me know.

[12:07] <woox2k> hello. Is there any way to command pi to go into sleep mode for certain time?
[12:08] <Jck_true> woox2k: Sleep mode in what sense?
[12:08] <woox2k> My pi runs on battery and it's only needed like 12hours a day, i would like to put it into sleep mode for the time it is not needed
[12:08] <woox2k> just to conserve power it uses
[12:09] <Jck_true> woox2k: You can't really shut down the CPU from linux - I supposed if you could put the CPU into a powersaving mode if you did bare metal programming
[12:09] <Jck_true> woox2k: But everything else on the board would still be drawing power...
[12:09] <woox2k> so no way to do that from software?

[12:10] <pksato> woox2k: no, RPI not have timer to wakeup RPi.
[12:10] <woox2k> okay

[12:10] <woox2k> then it has to be done with hw
[12:11] <pksato> And, I dont know if have supend mode.
[12:11] <Jck_true> woox2k: if you did bare metal programming you could maybe cook something up - But theres still no way to stop the rest of the hardware on the board
[12:11] <thescatman_> I have an idea
[12:11] <Jck_true> woox2k: Google turned this up on a quick search - Looks rather expensive though - http://spellfoundry.com/
[12:11] * sdel (~sdel@ip68-108-143-9.lv.lv.cox.net) Quit (Quit: Leaving)
[12:11] <woox2k> hmm it also has a solar panel attached to the battery, i wonder if i could use that to detect light and power off the pi entirely? it only need to be on in the dark
[12:12] <thescatman_> What if you were to get one of those power timers, then get it to shut down 5 minutes before the power timer turns off, then the power timer will turn on at the specific time
[12:12] * thescatman__ (~thescatma@unaffiliated/thescatman) has joined #raspberrypi
[12:12] <woox2k> oh that's a bit expensive :(
[12:12] * WLL (~WLL@unaffiliated/wll) Quit (Remote host closed the connection)
[12:13] <Jck_true> woox2k: Yeah - Just remember you need to cut the power to the board completely...
[12:13] <pksato> woox2k: you can use some real time chip, and wire alarm pin to RUN jummper on rpi (need some hw hacking).
[12:13] <Jck_true> A simple "halt" command barely affects your power comsumption
[12:14] <pksato> or, use more complex circuity to cut/uncut power.
[12:14] <woox2k> so reset "jumper" would not work?
[12:15] <woox2k> i have 4 channel relay system for my pi, if i could make up some circuit to detect light and switch on the relay to power the pi
[12:15] <woox2k> as in use the relay backwards, not controlled by pi but controlling the pi
[12:16] <woox2k> i could use one of those 4 channels for that, rest would still be controlled by pi but i wonder how could i do that
[12:16] <woox2k> i know a bit about electronics but that's not enough to know exactly how could i accomplish that task
[12:17] * kcj (~kcj@unaffiliated/kcj) Quit (Remote host closed the connection)
[12:17] <pksato> you can build a simple ligh detector using a phototransistor/diode and some logic port.
[12:17] <thescatman_> woox2k: so it's only battery and solar power?
[12:18] <Jck_true> woox2k: To make matters worse you need to signal the pi so it can shutdown cleanly and avoid SD card corruption...
[12:18] <woox2k> oh yeah
[12:18] <woox2k> darn i forgot that
[12:18] <Jck_true> Unless you can mount the card read only...
[12:18] <thescatman_> Otherwise i'd suggest this kinda thing http://www.amazon.com/Sunlite-05003-SU-T200-Heavy-Appliance/dp/B009XS1GJE/ref=zg_bs_495340_4
[12:18] <woox2k> that is not really an option, i need to take pictures
[12:18] * cameronfr (~cameronfr@ Quit (Quit: Textual IRC Client: www.textualapp.com)
[12:19] <thescatman_> maybe you can find a USB powered one of them, unless the solar panel is a plug socket one
[12:19] <woox2k> hmm or modify the mains one.... that might also work
[12:19] <Jck_true> What about a china arduino and a 5v relay?
[12:19] <woox2k> i have thought about it but at the moment i'll try to figure out something with things i have
[12:20] <woox2k> arduino would be the last resort
[12:20] <woox2k> i know that would work but it also costs a bit
[12:20] <Jck_true> woox2k: http://www.dx.com/p/itead-arduino-single-channel-relay-module-deep-blue-305518?Utm_rid=58973692&Utm_source=affiliate
[12:20] <thescatman_> actually if you could mod the mains one that could work and would be a lot easier...
[12:21] <Jck_true> thescatman_: Nice one
[12:21] <woox2k> i already have a 4channel relay like i said, it is also compatible with arduino
[12:22] <woox2k> mains one has logic running in decent voltages anyway, i would just have to modify the power supply
[12:22] <woox2k> i did it it my mains motion sensor once
[12:23] <thescatman_> I'm hoping the lapdock I picked up is going to give out enough power to my Pi 2 now it's overclocked actually :|

[12:25] <thescatman_> is that a pi 2 or 1?
[12:25] <woox2k> 1
[12:25] <woox2k> B+
[12:26] <woox2k> if i could boot it up like in 10secs or so then i could rethink everything we talked before :D
[12:27] <thescatman_> idk :/ maybe use a less intensive distro?
[12:27] <woox2k> as in i would make a motions sensor control the pi, if motion is detected it would boot up the pi, take a picture and shut down the pi again
[12:27] <thescatman_> if you could use a headless one maybe it would last longer on battery too

[14:29] <cehteh> native is softfloat
[14:30] <Tenkawa> cehteh: armhf isnt

[14:30] <cehteh> mhm .. whats the difference to raspbian then?
[14:30] <Tenkawa> I'm running it on this exynos box right now
[14:30] <cehteh> i can debootstrap a chroot
[14:30] <Tenkawa> cehteh: origin of the code and maintainers
[14:30] <Tenkawa> I already have too many seperatedistros
[14:31] <Tenkawa> I'm thinking of debootstrapping too just to test
[14:32] <cehteh> isnt raspbian just importing upstream debian package and adds its own bits (which are pretty minimal)
[14:32] <thescatman_> it also takes a lot out afaik
[14:32] <cehteh> i havent missed anything yet
[14:32] <thescatman_> idk, I don't use debian yet
[14:33] <cehteh> texlive-full on the rpi :D
[14:33] <teclo-> "takes a lot out" yes but... isn't it possible to just "aptitude install" the packages you don't have ?
[14:33] <cehteh> all of emacs ..
[14:33] <Tenkawa> cehteh: bah.. give me edlin
[14:33] <cehteh> Tenkawa: you'll try a debootstrap on your own?
[14:33] <Tenkawa> haahaahaa
[14:33] <Tenkawa> sure
[14:33] <cehteh> ed not edlin
[14:33] <Tenkawa> ed is newer
[14:33] <Tenkawa> edlin is way old
[14:33] <thescatman_> teclo-: dunno, my raspbian card corrupted and I haven't done a new one yet lol
[14:33] <teclo-> there's vim on raspbian
[14:34] <Tenkawa> nano ftw
[14:34] <Tenkawa> heehee
[14:34] <Tenkawa> pico
[14:34] <cehteh> dd
[14:34] <Tenkawa> yes I'm just odd
[14:34] <teclo-> thescatman_: heh I've also got a raspbian card that got corrupted
[14:35] <teclo-> a 8 GB Kingston one
[14:35] <teclo-> they say Kingston is the best, well uhhhh
[14:35] <thescatman_> did it kill the card too? or just corrupt it
[14:35] <Tenkawa> I just found out last night I bought 3 "same" sd cards from a local shop and 2 were the same howeer the 3rd was different
[14:35] <teclo-> thescatman_: well it won't boot
[14:35] <cehteh> Tenkawa: i havent noticed a difference between debian and raspbian yet
[14:35] <thescatman_> I'm fully expecting my micro SD to get murdered by my overclock soon

[14:36] <teclo-> by the way isn't there some way to mount /boot read-only ? You know, when you turn off the Pi without doing a shutdown, because you don't have a keyboard or networking, /boot gets corrupted and it won't boot
[14:36] <thescatman_> MarconM: Sandisk Extreme Pro 8GB
[14:36] <thescatman_> or is it the Sandisk Ultra

[14:36] <teclo-> Tenkawa: well one difference is that raspbian has its own repositories which differ from Debian....
[14:36] <cehteh> i know
[14:37] <MarconM> i bought a sdcard 128gb class 10
[14:37] <Tenkawa> teclo-: add it to the cmdline.txt boot options
[14:37] <MarconM> using freebsd and archlinux

[14:37] <teclo-> Tenkawa: ah, thank you, gonna do that
[14:37] <cehteh> but i live in .eu its a little bit saver to buy stuff here than elsewhere in the world i tihnk
[14:37] <Tenkawa> that "should" be able to mount it ro however dont quote me
[14:37] <thescatman_> cehteh: if I were you I'd email sandisk with pics of the front and back, and the codes that are on the card, and they will tell you if it's authentic. What is REALLY annoying is the front of the real-life cards usually look slightly different to the pics in their documentation
[14:37] <ozzzy> well this rocks... 802.11n wifi, 2.4GHz mouse/kbd, 320G USB2 hdd and a 32G stick all plugged into the Pi 2 and working
[14:37] <Tenkawa> if it does let me know because I want to do that too
[14:38] <cehteh> thescatman_: i just test sdcards carefully before using, when they survive that then its ok
[14:38] <cehteh> even if counterfeit, it works
[14:38] <Tenkawa> ozzzy: that does soud nice

[14:39] <cehteh> pull?
[14:40] <cehteh> you dont need to pull
[14:40] <Tenkawa> mine got scrambled.. I still got the .git >stuff though
[14:40] <cehteh> git clean -dfx deletes everything not in git (careful!)
[14:40] <Tenkawa> so I just need the command/s to recreate the tree
[14:40] <cehteh> git reset --hard resets all changed files and your branch
[14:40] <Tenkawa> ok
[14:41] <Tenkawa> thanks
[14:41] * [SLB] (~slabua@unaffiliated/slabua) has joined #raspberrypi
[14:41] <cehteh> doing that both gives you a quite verbatim tree, but i've warned you, it deleted anything not in git
[14:41] <Tenkawa> reminds me of when I use to be a source code admin
[14:41] <cehteh> and all your changes
[14:41] <cehteh> you can git stash changes away
[14:41] <cehteh> thats a bit safer
[14:41] <Tenkawa> cehteh: thats fine
[14:42] <cehteh> dont complain to me when your kernel .config gets lost :)
[14:42] * Tenkawa use to do this for a living.. granted it was back in 1996
[14:42] <Tenkawa> cehteh: cat /proc/config.gz >>keep_this_config afer every boot
[14:42] <Tenkawa> er after
[14:42] <Tenkawa> heheheh
[14:43] <cehteh> well unless you did changed it but didnt compiled and installed that kernel yet
[14:43] <Tenkawa> ooh much better.. thank you
[14:43] <Tenkawa> cehteh: not making any changes
[14:43] <cehteh> heh ok .. i have a somewhat customized kernel her
[14:43] <Tenkawa> just pulling latest kernel
[14:43] <Tenkawa> ahh
[14:43] <cehteh> git remote update; git reset --hard origin
[14:44] <cehteh> will do that
[14:44] <cehteh> maybe origin/master or whatever version you want
[14:44] <Tenkawa> there we go
[14:44] <Tenkawa> cehteh: you ever had to deal with svn?
[14:44] <Tenkawa> thats usually what I use

[14:47] <Tenkawa> with them not being armv7 thats a bit tougher
[14:48] <cehteh> give it away to some kids?
[14:49] <Tenkawa> I'm actually thinking about doing that and building a few up for a retirement home I work with
[14:49] <Tenkawa> there's a few there who want something to toy with and not some overly complicated computer
[14:50] <Tenkawa> nice small linux install with lxde should suit them fine
[14:50] <cehteh> but its not armv7 :)
[14:50] <Tenkawa> nope
[14:50] <Tenkawa> they dont care though
[14:50] <ozzzy> cehteh, what does that matter

[15:07] <Tenkawa> lets see...
[15:08] <Tenkawa> cehteh: ozzzy: how much amperage you pushing each with?
[15:08] <Tenkawa> trying to determine if 2.1 amp would be enough for 2
[15:09] <ozzzy> Tenkawa, dunno... but it's running on a 2A supply
[15:09] <cehteh> i never really used any much, only keyboard and mouse usually
[15:09] <cehteh> yes 2A supply here too
[15:10] <Tenkawa> so 2 headless (only using internal ethernet) should be fine sharing a 2.1 amp circuit
[15:10] <Tenkawa> right?
[15:10] <cehteh> i dunno how big the traces for the 5V lines are on the board, i wont draw more than 2A even with fuses shortened
[15:10] <cehteh> or rather better drive such a circruit externally
[15:10] <cehteh> or just try
[15:10] <Tenkawa> I just don't want to undercurrent it

[15:11] <cehteh> undercurrent?
[15:11] <thescatman_> Tenkawa: I could run 1 pi 2 at 100% load with 5V, 1A if that helps
[15:11] <thescatman_> not overclocked though
[15:11] <cehteh> max 2.5watts i read somewhere
[15:11] <Tenkawa> cehteh: 2 of them sharing 2.1 amps
[15:11] <thescatman_> that should be fine
[15:11] <Tenkawa> cool
[15:11] <Tenkawa> gives me more to work with
[15:11] <cehteh> just try, you'll notice when it fails
[15:11] <thescatman_> don't quote me though, I don't do electronics. just going off what has happened with mine
[15:12] <Tenkawa> I have a lot of 2 port usb plugs each rated for 2.1 ap
[15:12] <Tenkawa> er 5v/2.1 amp
[15:12] <cehteh> the core runs fine on way lower voltage than 5V .. only USB will give up pretty soon :D
[15:12] <thescatman_> seems to use <1A the vast majority of the time unless you're using power hungry usb stuff

[15:12] <Tenkawa> in theory it should be fine... IF the draw is what they are listed and rated at
[15:13] <Tenkawa> cehteh: well voltage better not fluctuae too much in general.. thats just not good
[15:13] <Tenkawa> the current can
[15:13] <Tenkawa> but it better stay around 5v at all times
[15:13] <cehteh> yes sure
[15:13] <Tenkawa> unless I'm forgetting everything about circuit draw
[15:14] <cehteh> thats why i always use a 2A power supply even with modest loads
[15:14] <Tenkawa> I try too
[15:14] <Tenkawa> I have some as small as 300 ma sitting around here
[15:14] <mortal> thescatman_: it seems that with a big heat sink I can get to 1050
[15:14] <Tenkawa> they are useless
[15:14] <thescatman_> mortal: what happens at 1100?
[15:14] <Tenkawa> thescatman_: probably meltdowm
[15:15] <thescatman_> Tenkawa: mine's stable at 1100
[15:15] <mortal> thescatman_: well I get kernel errors
[15:15] <thescatman_> ah ok
[15:15] <mortal> at load
[15:15] * Tenkawa wonders if the -2C temp outside would help
[15:15] <Tenkawa> haahaa
[15:15] <Tenkawa> er
[15:15] <Tenkawa> -2F
[15:15] <Tenkawa> even colder
[15:15] <mortal> thescatman_: is there a relationship between mem and arm freq
[15:16] <mortal> I got a clean boot with cold spray using a very little heat sink
[15:16] <mortal> so I researched using bigger heat sinks
[15:16] <thescatman_> you probably don't need a bigger one
[15:16] <mortal> well with the big one it is stable at 1050
[15:16] <mortal> otherwise I was able to clock only around 950 stable
[15:16] * Tenkawa just wishes his local shop would hurry up and get in cases or mounting plates at all for his boards
[15:16] <thescatman_> I found I couldn't get much more than 1GHz without increasing the memory clock or whatever it was (I'm not at home)
[15:17] <thescatman_> fair enough
[15:17] <thescatman_> you got a heatsink on whatever other chip is on the top?

[15:18] <mortal> thescatman_: yes
[15:18] <mortal> top chip
[15:18] <mortal> thescatman_: well should the mem clock be 1/2 of the cpu clock
[15:18] <thescatman_> the ram on the bottom gets hot too btw, it might help if you were to put one on that to
[15:18] <thescatman_> too*
[15:19] <thescatman_> mortal: that's what worked for me. Try upping the voltage another step
[15:19] <Tenkawa> anyone tried mounting them on their side?
[15:19] <thescatman_> mounting what?
[15:19] <Tenkawa> the board
[15:19] <thescatman_> onto what? (sry)
[15:19] <Tenkawa> give the heat a different dispersement channel
[15:20] <Tenkawa> thescatman_: whatever you are mounting your boards on
[15:20] <Tenkawa> or sitting the case on one of the sides to change the airflow
[15:20] <Tenkawa> or pushing air into/out of a case
[15:20] <thescatman_> not a bad idea but I doubt it'd make much of a difference
[15:20] <Tenkawa> I agree however it is an experiment to try if needed
[15:21] <thescatman_> I want to put a 1.2W 90mm fan onto it to disperse air a little more
[15:21] <thescatman_> Except I'm slightly more worried that it's going to give even more instability considering i'd be running 1.2w off the usb or gpio
[15:21] <Tenkawa> lets push one of units a bit harder shall we
[15:22] <thescatman_> If I was at home I'd be shoving it up to 1200 just to see what happens
[15:22] <Tenkawa> any of you found any specific uses for dtb vs non-dtb btw
[15:22] <Tenkawa> ?
[15:22] <thescatman_> 1150's the highest i've seen

[15:25] <thescatman_> wait I thought the stock was 500
[15:25] <clever> Tenkawa: before device-tree came out, i had to write a custom driver to configure the mpr121 touch sensor
[15:25] <Tenkawa> oh is it?
[15:25] <clever> but now that device tree is out, i could embed that config into a dtb file, and not have to compile things
[15:25] <Tenkawa> hmm it listed it in the overcock settings
[15:25] <Tenkawa> but yeah I agree that should be stock

[15:35] <thescatman_> surely not 250MHz

[15:37] <thescatman_> I couldn't find what clocks it goes to when idle
[15:37] <clever> thescatman_: when the arm idles, it basicaly shuts most stuff off
[15:37] <clever> so your power usage will be the same as if you just lowered the clock
[15:37] <thescatman_> is that an automatic thing, or do you need it to command it to do that
[15:38] <clever> the draw will depend more on how much clock cycles you actualy spend active
[15:38] <clever> its automatic
[15:38] <clever> when nothing needs the cpu, the linux kernel just runs an idle instruction
[15:38] <clever> then it wants for an interupt from something to resume execution

[18:24] <Sonny_Jim> Nope, you can't
[18:25] <Sonny_Jim> So you'd have to use a similar program and convince your users to use it also

[18:26] <Sonny_Jim> ie 5 mumble users, 5 forums uses and someone downloading the whole repo
[18:26] <kisak> murmur or umurmur should work
[18:26] <Sonny_Jim> The forum wouldn't use much bandwidth, not sure about mumble though

[18:27] <MY123> (if it's new enough)
[18:27] <JohnnyBitcoin> i want to just take the sd card from the pi b+ and put it into the pi 2.
[18:27] <JohnnyBitcoin> that will work?
[18:28] <MY123> JohnnyBitcoin, did you run "apt-get upgrade"?
[18:28] <kisak> JohnnyBitcoin: it needs to be updated to a post-pi2 release date
[18:28] <MY123> JohnnyBitcoin, if you ran it,yes
[18:28] <JohnnyBitcoin> i did
[18:28] <englishman> whats the best place to get a pi2 at the moment that takes paypal
[18:28] <JohnnyBitcoin> thanks
[18:28] <JohnnyBitcoin> englishman, amazon
[18:28] <englishman> nonusa
[18:28] <englishman> :)
[18:28] <ozzzy> I ordered mine from element14
[18:31] <ShorTie> did you run dist-upgrade too ??
[18:32] <kisak> I ordered one last friday when the semi-local preferred warehouse briefly had some stock, should arrive today or tomorrow
[18:32] <kisak> ^42 USD
[18:32] <englishman> some are in stock at pimoroni and pihut but these are almost 2x price
[18:33] <englishman> newark/element14 doesnt take paypal :(
[18:33] <ozzzy> well... if you want it now you pay for it
[18:33] <ozzzy> nope... but they take CC
[18:33] <englishman> yup, i will probably wait for availability
[18:34] <JohnnyBitcoin> will the pi2 be a good desktop?
[18:34] <MY123> JohnnyBitcoin, yeah if you use DRM/KMS and enable Unity
[18:34] <ozzzy> JohnnyBitcoin, if you don't mind slow
[18:35] <kisak> JohnnyBitcoin: 1GB of ram makes it possible to run a mainstream browser with one or two tabs

[19:40] <gnatt> Hi. I have a raspberry pi I'm trying to use to control solenoids for a kegerator. It was working great until I came back one day and the screen only shows "sh unable to connect to tty; job control turned off" I've tried googling it and I've added avoid_safe_mode=1 to /boot/config.txt. I'm hoping I didn't fry the pi with the solenoid's power supply
[19:41] <heller\> tried another sd?

[19:44] <Gadgetoid> englishman: and we'll love you forever <3 :D
[19:45] <gnatt> IT_Sean, no I was using a powersupply plugged into the wall and I was opening and closing the solenoid with a transistor connected to a GPIO pin
[19:45] <englishman> i didnt see an option for buying without the case, if there is one
[19:45] <IT_Sean> try a different SD.
[19:45] <englishman> but i probably would have since its not too spendy
[19:45] <gnatt> Also, I was using a flyback diode. and it was working fine until it broke.
[19:45] <Gadgetoid> englishman: Sadly there's just no use selling them on their own, no margin :(
[19:46] <gnatt> Okay, I'll try a different SD. Thanks.
[19:46] * LoneElf (~textual@ has joined #raspberrypi
[19:46] <englishman> :(
[19:46] <englishman> i guess guys like you have to get them from newark/rs like everyone else?
[19:46] <Gadgetoid> Basically, yes
[19:46] <gnatt> IT_Sean, can I just burn the SD i have now onto a new SD or would that make it not work?
[19:47] <IT_Sean> you can take an image of the current SD and image it to a new card, but, the idea is to rule out an issue with the SD. Try a new SD with a fresh OS. Just to see if the Pi will boot it.
[19:47] <IT_Sean> if the Pi doesn't boot a new SD with a new OS, it's toasted. If it does, work backwards from there.
[19:47] <gnatt> Okay. Thanks again

[20:52] <derpingit> hi guys
[20:53] <derpingit> anyone know if i can use my tv usb to power the new pi2?
[20:53] <aberrant> I wouldn’t suggest it if it’s a standard 5W USB - my rpi2 can draw more than 1A.
[20:55] <derpingit> dang it :/ . any PoE adapters?
[20:55] <IT_Sean> derpingit: as long as it supplies enough current, you can.
[20:56] <derpingit> IT_Sean .. how will i know tho
[20:56] <IT_Sean> try it and see if it works.
[20:56] <IT_Sean> you won't harm anything by trying.
[20:56] <aberrant> derpingit: one other option is one of those batteries with USB output - some of them can provide 10W and draw from 5.
[20:56] <derpingit> my board is on its way and i didn;t get an adapter
[20:57] <aberrant> well, you’ll waste a bunch of time when your sd card gets corrupted due to undercurrent
[20:57] <derpingit> ah ok
[20:57] <IT_Sean> aberrant: there is no need to be hostile.
[20:57] * aberrant wasted the better part of a day on this issue.
[20:57] <aberrant> who’s hostile?
[20:57] <Armand> ME! >_<
[20:58] <Armand> What are we talking about?
[20:58] <aberrant> I dunno how what I said got misconstrued - but I spoke from direct experience :)
[20:59] <Digit> the royal "you"
[20:59] <Armand> FWIW: My rPi model B runs perfectly well from a USB battery pack
[20:59] * hamrove (~hamrove@96-8-209-215.block0.gvtc.com) Quit (Quit: hamrove)
[20:59] <aberrant> Armand: the model B is fine with 5W. The RPi2 can exceed 5W draw on large loads.
[20:59] <Armand> 18000mAh. 1x 1A USB + 1x 2A USB
[21:00] <aberrant> that 2A USB would be ideal for an Rpi2
[21:00] <Armand> Yeah, I've not got the rpi2.. I'm eyeing up group of C1s
[21:02] <aberrant> the rpi2 is blazingly fast compared to previous models
[21:02] <aberrant> plus it’s a true arm7
[21:03] <derpingit> aberrant which pack?
[21:04] * speeddragon (~speeddrag@ has joined #raspberrypi
[21:04] <aberrant> derpingit: check with armand. Any one that can do 2A @ 5V should be fine.
[21:04] <IT_Sean> I have an ANKER battery pack that claims 2A. Never tried it w/ a Pi tho
[21:05] <derpingit> oh i have an anker pack ..i will ttry that
[21:05] <derpingit> the thing tho, is that the anker doesn't charge and supply power at the same thime
[21:05] <IT_Sean> Actually, i stand corrected... this says 5v @ 1A. Sorry.
[21:05] <derpingit> time*
[21:05] <aberrant> derpingit - that’ll be a problem then
[21:06] <aberrant> can you bond two USB ports to supply 2A @ 5V somehow?
[21:06] <derpingit> lol. that's what i was thinkin
[21:06] <derpingit> it can't be that simple tho
[21:06] * x1337807x (~x1337807x@207-170-205-178.static.twtelecom.net) Quit (Quit: My MacBook Pro has gone to sleep. ZZZzzz…)
[21:06] <IT_Sean> it doesn't work that way, aberrant... Unless they are on seperate USB channels, with seperate power supplies.
[21:07] <IT_Sean> just splicing in a 2nd port isn't gonna do anything :p
[21:07] <Syliss> if you can, just pick up a cheap-ish ipad charger and that will work wonders
[21:07] <aberrant> IT_Sean: are you sure? each usb port must supply 1A @ 5V. If you bond two of them together, you should be able to draw 2A.
[21:07] * t0x0sh (~tosh@t0x0sh.org) Quit (Ping timeout: 255 seconds)
[21:08] <IT_Sean> aberrant: depends on the ports... if it's just a cheap hub, that's not gonna necessarily be the case.
[21:08] <IT_Sean> I'm just trying to tell you that is not a "100% works every time" universal solution.
[21:08] <aberrant> if that’s the case then you wouldn’t be able to power more than one device off of it.
[21:09] <IT_Sean> Clearly you haven't seen some of the shoddy USB hubs I have :p
[21:09] <aberrant> hah, true
[21:09] * ctarx (~ctarx@p508FEDF5.dip0.t-ipconnect.de) has joined #raspberrypi
[21:09] <aberrant> actually, I stand corrected. the MINIMUM max draw for usb 1 is 100mA

[22:27] <Gadgetoid> englishman: Damn, that's a toughie- probably Display-o-Tron 3000, which might be my favourite of our products
[22:28] <IT_Sean> is that that LCD w/ the RGB backlight?
[22:28] <Gadgetoid> IT_Sean: aye!
[22:28] <thescatman> Say I put 7V at 1.1A into a power plug that supplies 5V@up to 2A
[22:28] <IT_Sean> I saw that the other day. Looks neat!

[23:07] * denete (~denete@ Quit (Remote host closed the connection)
[23:07] <Gadgetoid> Most of my electronics experience seems to revolve around making extremely creative and unlikely errors in Eagle schematics and layouts
[23:08] <thescatman> I was going to put about 12 together, then use either something like this: http://www.amazon.co.uk/Converter-Power-Regulator-Voltage-Step/dp/B00E5VGWT8/ref=sr_1_4?s=electronics&ie=UTF8&qid=1424727764&sr=1-4&keywords=12v+step+down+to+5v
[23:08] <thescatman> or a car plug to usb adapter
[23:08] <thescatman> to dc-dc 12V down to 5V@1A to power a pi (purely for the fun of it and to see if it'd work)
[23:08] <NGC3982> Simply putting foil and acids in a jar will never make 7V
[23:08] <NGC3982> It make 2, or 18, or something in between for a brief moment.
[23:09] <NGC3982> And you will never - ever - power a Pi with it.
[23:09] <NGC3982> A regulator might make it work, but i fail to see the purpose then.

[23:15] <thescatman> It definitely gets far hotter than the pi 1 at high clock speeds
[23:16] <NGC3982> Using the raspi-config overclock utility in B+, temperature would never reach (afaik) <85C, and did not suffer anything from it.
[23:16] <NGC3982> More than SD cards and data corruptions.
[23:16] <thescatman> indeed
[23:16] <NGC3982> thescatman: Oh, i see.
[23:17] <thescatman> hm?

[23:20] <thescatman> As I've found very little info on it by the way, it seems to clock up to 1100MHz pretty easily but it does require a heatsink. Haven't tried higher yet.

[23:38] <fsa317> Working on building a project and I'm getting low voltage warnings that come and go on my screen. Using a MM I see small drops to around 4.6V. The drops seem to occur the more intense what I'm doing is. I'm trying to understand how that would effect voltage?
[23:39] <fsa317> My setup is a 5v 3A power cord powering a USB hub. The hub then powers my Pi and an exnternal HDD. The power cord has been cut and a disconnect added. With just the cord plugged in I got a stable 5.2V. I'm trying to figure out a) Do I need to worry about this and b) how can I debug further?

[23:48] <derpingit> hey guys... can the pi2 mount an external usb drive ?
[23:48] <clever> fsa317: i would check the resistance of the usb cord, and then look up ohms law to see how much voltage you would loose at typical currents
[23:48] <derpingit> i'm concerned abouto the power requirements
[23:49] <clever> derpingit: then use an external powered hub
[23:49] <derpingit> i just ordererd a 2a 5v adapter
[23:49] <Xark> derpingit: If you have a powerful enough supply (~2A) I think it is fine.
[23:49] <derpingit> don't wanna use a hub..so you;re saying it won't power one ?
[23:50] <clever> its a bit limited on how much current it can pass on to the usb port
[23:50] <derpingit> yeah i got an anker 2a usb power brick

[23:50] <derpingit> oh damm.. sorry bout the linky
[23:51] <Xark> clever: I was under the impression that B+ and Pi 2 would be OK for~500mA USB power (given sufficient input power).
[23:51] <ozzzy> Xark, as long as you don't want to plug anything into them

[23:51] <Xark> ozzzy: ?
[23:52] <ozzzy> oh sorry... I see what you mean
[23:52] <ozzzy> I thought you wanted to power the Pi with 500mA
[23:52] <ozzzy> LOL
[23:52] <Xark> ozzzy: Yeah, talking "output". :)
[23:52] <ozzzy> the Pi2 will power a usb2 hdd, a 32g memory stick a wifi dongle and a 2.4ghz mouse/kbd dongle
[23:52] <ozzzy> on a 2A supply
[23:52] <Gadgetoid> RichiH: Are you "rgh"?
[23:52] <fsa317> I pluged a USB cable that was cut into the hub, and it gets a pretty stable 5V
[23:52] <Xark> ozzzy: Cool. That is what I hoped (and had heard).
[23:53] <teknic111> just got my pi2 and want to use the same raspbian sd on my pi b+. What must I do to get it to work? Is it even possible?
[23:53] * Xark is preparing a SD card for his new RPi2...
[23:53] <ozzzy> http://ozzzy.dyndns.org:8080/images/pi2.jpg
[23:53] <Xark> teknic111: I think newer Rasbian (e.g.) work on both
[23:53] <RichiH> Gadgetoid: no
[23:54] <Gadgetoid> So many Richard H's floating around!
[23:54] <fsa317> So can having more things plugged into the pi cause the voltage to drop?
[23:54] <fsa317> My Pi has a BT adapter, Wifi and a IR Reciever
[23:54] <ozzzy> I just power mine with the supply that came with my Nexus 7
[23:54] <teknic111> I have the latest version, but when i put the sd card into the pi2, all i see is the multicolor screen at boot. It just stays at that screen. What am I doing wrong?
[23:54] <Xark> fsa317: Sure, if supply is weak. Wifi in particular can be a large power draw
[23:55] <derpingit> is the odroid c1 a variation of the rp2 ? . sorry if this this a stupid question. it keeps coming up on my searches
[23:55] <Xark> derpingit: Not really.
[23:55] <teknic111> i even went to the overclock settings and selected the stock pi2 config

[23:57] <fsa317> Xark: so thats probably what I'm missing here is that the measurements without load aren't that useful
[23:57] <thescatman> Xark, sorry if someone else mentioned it, but you might have problems powering a usb hard drive if it's not on a powered usb hub or mains power
