[1:30] <shing_> hi
[1:30] <shing_> i'm trying to diagnose an issue with my wifi disassociating from the ap. when running iw event -f i noticed a line indicating that the client is sending a deauth frame due to inactivity (reason code 4). i thought it was power managment at first but iwconfig is telling me it's off
[1:30] <shing_> anyone have any ideas?
[1:31] <teclo-> hello how can I use fbi on a Raspberry Pi ?
[1:31] <teclo-> I'm doing fbi -d /dev/fd0
[1:31] <ozzzy> depends... what's fbi
[1:32] <teclo-> fbi is a program to display pictures on the framebuffer
[1:33] <Tachyon`> fb0 surely
[1:33] <Tachyon`> wouldn't fd0 be an old floppy device name?
[1:34] <teclo-> yes fb0 :)

[1:36] * D-Boy (~D-Boy@unaffiliated/cain) Quit (Excess Flood)
[1:36] <teclo-> the picture doesn't show up
[1:36] <ozzzy> don't you have to tell fbi what picture?
[1:37] <ali1234> is the "screen saver" on?
[1:37] <mitchtay> Are you running it inside or outside of an xsession?
[1:37] <teclo-> using "DejaVu Sans Mono-16", pixelsize=16.67 file=/usr/share/fonts/truetype/ttf-dejavu/DejaVuSansMono.ttf
[1:37] <teclo-> ioctl VT_GETSTATE: Invalid argument (not a linux console?)
[1:37] <mitchtay> as which user? And are they part of the video group?
[1:37] <teclo-> mitchtay: outside of X
[1:37] <teclo-> mitchtay: as root
[1:37] <teclo-> mitchtay: but the pi user is part of the video group, too
[1:38] <ali1234> use dispmanx instead
[1:38] <teclo-> aaah wait :)
[1:39] <teclo-> fim works very well !

[6:29] <undecim> Can you paste a sample output with the line you're looking for?
[6:29] <undecim> without awk*
[6:30] <shing_> well at this point i'm just trying to get it to find any line from iw event -f
[6:30] <shing_> so for an example
[6:31] <shing_> let's say we find any line that contains wlan0
[6:31] * armin (~armin@unaffiliated/armin) has joined #raspberrypi
[6:31] <shing_> wlan0 (phy #0): scan started
[6:31] <shing_> would be one such line
[6:32] <armin> hi. what's the recommended chipset for a usb wifi adapter nowadays? any recommendations what to buy that will be fine?
[6:32] <undecim> shing_, Does 'iw event -f > outputfile' work?
[6:33] <shing_> yeah that should work, but i was hoping to skip the outputting to file
[6:33] <McBride36> armin, are you looking for a usb wifi rec?
[6:33] <undecim> shing_, I just want to make sure stdout is working
[6:33] <armin> McBride36: what's a rec?
[6:33] <shing_> i can run it
[6:33] <McBride36> recommendation
[6:33] <armin> McBride36: yes.
[6:33] <McBride36> http://www.amazon.com/Edimax-EW-7811Un-150Mbps-Raspberry-Supports/dp/B003MTTJOY/ref=sr_1_1?ie=UTF8&qid=1425101614&sr=8-1&keywords=usb+wifi+raspberry+pi
[6:34] <armin> McBride36: isn't there something with 300mbps that is recommendable?
[6:34] <shing_> undecim, yes it works
[6:34] <McBride36> idk, i'm lazy and use ethernet
[6:34] <undecim> shing_, Can you awk that file?
[6:34] <McBride36> you'd have to look around, i woudln't know
[6:34] <armin> ty
[6:34] <armin> :)
[6:34] <shing_> sure that works, but again i was hoping to skip outputting to a file
[6:34] <undecim> that's weird
[6:35] <shing_> but i guess awk is purely for files, can't pipe in data?
[6:35] <undecim> You can
[6:35] <undecim> I've done it
[6:35] <undecim> you're using bash?
[6:35] <shing_> what ever is the default on raspbian
[6:36] <undecim> what if you do iw | tee /dev/null | awk ?
[6:36] <undecim> or just cat instead of the tee command
[6:39] <shing_> hm
[6:39] <shing_> let me try it
[6:40] * NedScott (~nedscott@kodi/staff/nedscott) has joined #raspberrypi
[6:43] <shing_> doesn't seem to work
[6:43] <undecim> Could also try using grep + cut instead of awk
[6:44] <undecim> I can't understand why the file works, but awk doesn't, unless one of the components is doing a character translation of some kind
[6:46] <shing_> not working with grep either
[6:46] <shing_> i also tried jsut iw event -f | grep auth
[6:46] <shing_> this also doesn't find anything
[6:47] <shing_> nevermind grep works
[6:48] <shing_> i shouldn't of searched auth
[6:48] <shing_> maybe same issue with awk, checking
[6:54] <shing_> no it doesn't
[6:54] <shing_> can you explain it to me, why pipe to /dev/null then awk?
[6:56] <undecim> shing_, I was trying to do with tee exactly what cat does
[6:56] <undecim> And after I typed it, I thought "oh yeah, cat"
[6:57] <undecim> what is the exact commmand you are using?
[6:57] <shing_> alright i think i don't know how to write the command
[6:58] <shing_> lets say i'm looking wlan0 again
[6:59] * [Saint] (77e024ef@rockbox/staff/saint) Quit (Ping timeout: 246 seconds)
[7:00] <shing_> would i do iw event -f | cat /dev/null | awk '/wlan0/ {print $0}'

[7:01] <shing_> from the iw event -f output

[7:04] <shing_> wait
[7:04] <shing_> i let it run for a min

[11:39] <paxcoder> Hello all. Is there a quck&easy way to make Raspbian "libre"? It unfortunately comes preinstalled with non-free software (because wow minecraft! Such cool. Much educational). Is there vrms for rapsbian, can I use that after removing the non-free apt source to use only free software?
[11:41] <mgottschlag> paxcoder: I don't know, but keep in mind that the pi won't work without the bootloader/gpu blob
[11:41] <ShorTie> there is stuff in the non-free sources that mustbe used i believe
[11:42] <paxcoder> mgottschlag, whatever happened with "we're working to free that up"? I can understand they failed with the gpu, but bootloader? Why does a bootloader need a blob?
[11:44] <paxcoder> *failed with the gpu 3d acceleration
[11:44] <mgottschlag> heh, actually it is the other way round, GPU 3d acceleration is pretty much open source already
[11:44] <mgottschlag> not just the old blob wrapper but a real ARM-based 3d driver
[11:45] <paxcoder> mgottschlag, yeah, but that's the part that needs a blob to use
[11:45] <paxcoder> *with my desktop PC Radeon
[11:45] <paxcoder> I can use 2D without the blob
[11:45] <paxcoder> with just the generic driver
[11:46] * Slippern (~Slippern@76.109-247-208.customer.lyse.net) has joined #raspberrypi
[11:46] <mgottschlag> huh, but that doesn't have anything to do with the situation on the pi
[11:46] <mgottschlag> as I understood it, Eric Anholt's GPU driver works without interaction with the blob
[11:46] <paxcoder> o.O
[11:46] <paxcoder> what's the blob for then?
[11:46] <mgottschlag> now, why they didn't open source the boot loader, I don't know
[11:47] <mgottschlag> well, it used to contain most parts of the GPU driver, and still does for default installations
[11:47] <mgottschlag> and video decoding, etc
[11:47] <Helldesk> accelerated graphics, right?
[11:47] <mgottschlag> but it also contains power management and system initialization
[11:47] <mgottschlag> Helldesk: yeah, but those parts can be replaced by an ARM-based GPU driver if desired
[11:47] <mgottschlag> such a driver is in the works
[11:48] * paxcoder just noticed ARM-based
[11:48] <mgottschlag> although the VideoCore CPU might be more suitable - if there is an offload engine for things like shader compilation, it should be usable
[11:48] <mgottschlag> the pi has quite some different types of CPUs :D
[11:48] <paxcoder> mgottschlag, wait, the GPU blob contains power management?
[11:49] <mgottschlag> I think so, I might be wrong though
[11:49] <Helldesk> what I would most like to see is a way to drive any physically/electrically compatible display panel directly from the DSI connector but that's in the blob+NDA territory :/
[11:50] <Helldesk> designing a pocketable pi with a display that isn't a gpio hack is a non-starter
[11:50] * paxcoder begins to think of fsf-style pet names for pi. poisonberrypi? raspberrylie?
[11:51] <Helldesk> what?
[11:51] <paxcoder> Helldesk, you know, like iBad?
[11:52] * skyroveRR (~skyroveRR@unaffiliated/skyroverr) Quit (Read error: Connection reset by peer)

[11:52] <mgottschlag> sorry, I really can't take anyone serious who uses such names :D
[11:53] <paxcoder> tis silly
[11:53] <Helldesk> me neither, sounds petty
[11:53] <Helldesk> what's the point exactly?
[11:54] <paxcoder> Shaming, obviously.
[11:54] <paxcoder> Anti-propaganda
[11:54] <Helldesk> self-shaming foundation
[11:54] <paxcoder> o.O
[11:54] * sphenxes (~sphenxes@178-190-233-165.adsl.highway.telekom.at) has joined #raspberrypi
[11:54] <Helldesk> sorry but that's the first impression I get :)
[11:54] * sphenxes (~sphenxes@178-190-233-165.adsl.highway.telekom.at) Quit (Max SendQ exceeded)
[11:55] <paxcoder> How are they shaming themselves?
[11:55] <paxcoder> By shamming Apple's products?
[11:55] <mgottschlag> paxcoder: Yeah, except that's totally not how marketing works. You'll achieve exactly the opposite in many cases.
[11:55] * sphenxes (~sphenxes@178-190-233-165.adsl.highway.telekom.at) has joined #raspberrypi
[11:56] <paxcoder> mgottschlag, the trouble is that nobody cares. "Xbone" (not theirs) was a successful antislogan I think.
[11:56] * skyroveRR (~skyroveRR@unaffiliated/skyroverr) has joined #raspberrypi
[11:56] <Helldesk> that's different, it's a pet name
[11:56] <mgottschlag> well, I don't think it was
[11:56] <mgottschlag> thing is
[11:57] <mgottschlag> nobody cares atm, and you want to change that
[11:57] <paxcoder> Digital Restrictions Management is a good one.
[11:58] <mgottschlag> these stupid names will certainly have a positive effect on those who care
[11:58] <Helldesk> I don't know who came up with xbone but it's an initialism and a portmanteau rolled up in one
[11:58] <mgottschlag> but those who don't care will think "what a bunch of childish idiots"
[11:58] <paxcoder> Helldesk, it wasn't coined out of endearment.
[11:58] <mgottschlag> you'll end up radicalizing people, and you'll harden the frontier between both groups
[11:58] <mgottschlag> but that's pretty much ot
[11:58] <mgottschlag> it
[11:58] <Helldesk> I don't know about that but to me it sounds like just a fun play on words
[11:59] <Helldesk> anyway, none of this matters if you care about software licencing
[11:59] <paxcoder> As I recall it was a poke at the name One which was ungooglable.
[11:59] <paxcoder> And general PS fanboyism I guess.
[12:00] * Xano (~bart@ has joined #raspberrypi
[12:00] <paxcoder> So what does the bootloader blob do?
[12:00] <ali1234> everything?
[12:01] <paxcoder> O_O
[12:01] * j416 (~j416@unaffiliated/j416) Quit (Ping timeout: 245 seconds)
[12:01] <mgottschlag> starting the ARM core, loading the kernel, setting up clocks, decoding videos, compiling shaders and accellerating 2D and 3D operations, and probably power management.
[12:01] * utack (~utack@ip9234cb8c.dynamic.kabel-deutschland.de) has joined #raspberrypi
[12:01] <mgottschlag> oh, and audio also is implemented in the blob afaik
[12:02] <paxcoder> geez
[12:02] <mgottschlag> because audio on the pi is not much more than some PWM controlled via DMA from software
[12:02] <paxcoder> An open platform my behind.
[12:02] * monocle is now known as zz_monocle
[12:02] <ali1234> yeah there is basically nothing open about it in the slightest
[12:03] <ali1234> it's certainly significantly less open than a typical PC with proprietary graphics drivers and bios
[12:03] * AbouEmre (~Thunderbi@ Quit (Remote host closed the connection)
[12:03] <mgottschlag> ... but then, the alternatives usually are not better.
[12:03] <mgottschlag> ali1234: no, it isn't, it's pretty much the same
[12:03] <paxcoder> mgottschlag, are you sure about that? Doesn't get much more closed than this.
[12:03] <mgottschlag> in the typical PC, all kinds of components contain closed-slurce firmware
[12:03] * AbouEmre (~Thunderbi@ has joined #raspberrypi
[12:03] <mgottschlag> the BIOS is closed source as well (usually), and the CPU also contains several blobs which run in parallel with the operating system
[12:04] <ali1234> okay i'll give you that
[12:05] * Datalink_ (Datalink@unaffiliated/datalink) Quit (Ping timeout: 250 seconds)
[12:05] <mgottschlag> a lot of ARM boards are better in that only small parts of system initialization are closed-source, and then during runtime only the GPU driver is a blob
[12:05] <mgottschlag> so yeah, a bit better, but not exactly good either
[12:05] <paxcoder> mgottschlag, get CoreBoot, a wired connection, setltle for 2D graphics (or Intel graphics) and with linux-libre you have no blobs, do you?
[12:06] <ali1234> no there are still firmwares in eg your network card
[12:06] <mgottschlag> forget it, modern Intel or AMD CPUs run several blobs which you cannot disable
[12:06] <paxcoder> ali1234, there's a difference between non-flashable firmware and firmware blobs.
[12:06] * skylite_ (~skylite@business-178-48-4-145.business.broadband.hu) has joined #raspberrypi
[12:06] <ali1234> if you want a 100% open computer, get an arduino
[12:06] <mgottschlag> e.g. Intel's Management Engine (signed and cannot be replaced, and if removed, the CPU will shut itself down after 30mins or something like that)
[12:07] <mgottschlag> paxcoder: this firmware can almost always be updated
[12:07] <paxcoder> mgottschlag, network card firmware?
[12:07] <mgottschlag> a more popular example are for example SSDs/HDDs
[12:07] <mgottschlag> but I am pretty sure the same applies to network cards
[12:07] <ali1234> yeah nobody uses mask rom
[12:07] <ali1234> *any more
[12:07] * pksato (~PEBKAC@unaffiliated/pksato) has joined #raspberrypi
[12:08] <mgottschlag> at least it is valid for wifi chips, but network cards will be the same
[12:08] <paxcoder> i said a wired connection
[12:08] <paxcoder> i know you need blobs for wifi
[12:08] <ali1234> you can install linux on your hard drive
[12:08] <paxcoder> wut
[12:08] <paxcoder> can you really?
[12:08] <ali1234> i mean literally on the hd controller chip
[12:08] <paxcoder> I've never heard of this been done
[12:09] <paxcoder> Are you sure they're powerful enough?

[12:09] <paxcoder> but is the hd usable then?
[12:09] <ali1234> yes, actually
[12:10] <ali1234> of course you can't use a pi without some type of storage either, so it's not like it wins there either

[12:46] <mgottschlag> well, I think that should work if you use 13.8V. Be careful with the voltage, or the battery will start to produce hydrogen and explode :)

[12:47] <ShorTie> trickle charge/normal charge/fast charge are 3 different animals
[12:47] <heller\> hmm
[12:47] <heller\> if a polyfuse says 4 on top of it, what does it mean?

[12:53] <heller\> but with small current ofc.
[12:54] <mgottschlag> a potentiometer is not good for voltage regulation
[12:54] * skyroveRR (~skyroveRR@unaffiliated/skyroverr) has joined #raspberrypi
[12:54] <mgottschlag> you can use it to limit current, but the voltage output will be rather unregulated
[12:54] <ShorTie> i would guess it depends on how much redisigning you want to do
[12:54] <heller\> But i could use potentiometer to simulate battery voltage just to see how a script works when trying to read battery voltage?
[12:54] <mgottschlag> you'd need a proper voltage regulator for good results, e.g. lm317
[12:54] <mgottschlag> yeah, that would work
[12:54] <heller\> yeah lm317 would bee more accurate
[12:55] <heller\> but basically the idea of using +12V and -5V is okay?

[17:33] <shiftplusone> introducing potential voltage drops to the pi's power supply is a bad idea
[17:33] <shiftplusone> Froolap: ah... can't speak for pidora/fedora.
[17:33] <Ryzari> meh, i run my pi2 off it and it's not once shown the low power indicator
[17:34] <Froolap> i was reading that there was supposed to be something different to support the quad core cpu....
[17:34] <Froolap> but I'm not seeing a listing of This is for the B+ and this is for the 2b
[17:35] <shiftplusone> Froolap: an armv6 userland will work just as well on the pi2. It just needs a different kernel.
[17:35] <Froolap> yeah well, I guess I'm out of luck then.
[17:35] <shiftplusone> For example, the raspbian image works on the pi1 and pi2. I don't know about pidora though.
[17:36] <shiftplusone> Froolap: just try the image and see if it works. You can run rpi-update to force it to work.
[17:36] <Absalom> Since I am using my own (ancient model) RPI only on the console, I have no real idea concerning the following project for my son; Rpi2 + window manager + USB sound card + midi input + jack midi/audio + various synthesizers, real time music purpose.
[17:36] <Absalom> Is it powerful enough?

[17:51] <SpeedEvil> You are not controlling the brushless motors with PWM
[17:51] <DoctorD90> i have find out a store in my city that sell yet made quadcopter. they use some little pre-made board that only need to be linked to radio-controller and motors, so people in the store dont know very wel help me. but they show me motor used in quadcopter
[17:51] <SpeedEvil> you would be controlling the brushless motor drivers with PWM
[17:51] <SpeedEvil> you use the same drivers - ESC - electronic speed controllers - that are used for R/C
[17:52] <DoctorD90> they show me brushless motor with 3 cable to ontroll, and they tells me that each brushless motor needs a regulator....so my confusion-entropy....INCREASE XD
[17:52] <SpeedEvil> You do not want to make your own motor controllers.
[17:52] <SpeedEvil> use conventional speed controllers, they work well.
[17:53] <smoothifier> hi folks :) i'm an intermediate programmer and i'd like to try to port the current ioquake3 code to the pi. i have gotten the regular port working, but i'm interested in doing it with the newer code base. i'm not very familiar with opengl. does anyone have any suggestions? any help is appreciated. thanks!
[17:53] <DoctorD90> SpeedEvil, and how can i control this ESC ? :P
[17:54] <SpeedEvil> the above board.
[17:54] <SpeedEvil> They require PWM to control them.
[17:54] <SpeedEvil> 0.3-1.2ms on, 20ms off (from memory)
[17:54] <SpeedEvil> 0.3 is 'off' 1.2 is full
[17:54] <DoctorD90> so i have to find out the brushless motor + this controller, and send to it the pwm, or it is an unique motor with chip inside?
[17:55] <SpeedEvil> All ESCs work to the same standard
[17:55] <Absalom> Another project: what I love with my old RPi aold B model is that I can leave it alone at home for days, computing at CPU 100% (C or Fortran scientifical algorithms): no heat, no need for any radiator, etc. I heard that new RPi 2 heats; is a radiator necessary?
[17:55] <SpeedEvil> Absalom: A fan is not usually needed.
[17:56] <SpeedEvil> Is it in a room temperature environment, or a box which may go to 50C?
[17:56] * Macuser (~textual@unaffiliated/macuser) Quit (Ping timeout: 252 seconds)
[17:56] <DoctorD90> so i have to looking for an ESC board, and i send to it the pwm signal, and it sends to brushless motor? i have well translate? :)
[17:56] <Absalom> My current RPi (old model) isn't in a case; just on my work table.
[17:56] <Absalom> Thus: room temperature.
[17:57] <Absalom> I would like to buy the new RPi2, but I would like the same usage.

[18:00] <DoctorD90> SpeedEvil, the shopper show me (explain it) the size....i was thinking to a 250 :)

[18:00] <SpeedEvil> 250kg?

[18:01] <teclo-> shiftplusone: ah you work for Raspberry Pi ? ;à
[18:01] <DoctorD90> ehm...lol....so in each region "size" meaning change.....here in italy (i think basing my knowledge from what shopper explain me) 250 is the diagonal from 2 opposite motors :)
[18:01] <SpeedEvil> ah
[18:02] <DoctorD90> Encrypt, ?? xD i controlled rpi trough eth only at first launch to set wifi xD i think you are confusing me with another user XD
[18:02] <SpeedEvil> Google and find out what people are using for wattage of motors and you probably want to at least match it
[18:02] <Encrypt> DoctorD90, Hum, maybe :/

[18:02] <SpeedEvil> DoctorD90: Also, check local laws. It may not be legal to operate.

[20:19] <DJRWolf> Looking at what I can use to power a cluster of Pi 2's clocked at 1.2 Ghz. Looking at this:
[20:19] <DJRWolf> http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=8916418&srkey=FLT-102341233
[20:19] <DJRWolf> They will be "headless" so only will have network cable hooked in.

[20:26] <TheLostAdmin> DJRWolf. From what I understand 2 Amps is more than enough for a RPi2 and should have enough to drive the USB ports if needed. I haven't test it myself.
[20:26] <TheLostAdmin> Personally I wouldn't trust TigerDirect. I would find a different supplier.
[20:27] <TheLostAdmin> As headless (and assuming you aren't trying to power any USB attached hard drives (the spinning kind) that is definitely plenty of power (based on the specs I've read).

[20:30] <shiftplusone> DJRWolf: interesting. DO you have one of those laready?
[20:31] <shiftplusone> I'm planning a little pi2 cluster, but haven't settled on how to power them... that looks reasonable.
[20:32] <shiftplusone> I was leaning towards an ATX supply, but I've seen people get out of spec voltages out of them, so I don't know.

[20:37] <ali1234> yeah you have to build it in to a proper case
[20:37] <MY123> or you can fry something
[20:37] <shiftplusone> MY123: why's that?
[20:38] <ali1234> because that's how they are designed to be used
[20:38] <ali1234> they expect a certain load on each supply
[20:38] <MY123> shiftplusone: the power-supply has some mutualised components inside to have more efficiency
[20:38] <Ryzari> these psus he linked are dedicated 5v, so doesn't matter
[20:38] <shiftplusone> Ryzari: yeah, but I mentioned ATX supplies earlier as well.
[20:38] <ali1234> yeah, i linked a dedicated PSU because it doesn't have this problem
[20:39] <mgottschlag> I think there are quite some modern ATX supplies which don't require as much load
[20:39] <MY123> mgottschlag: That's what is written in the spec
[20:39] <shiftplusone> well, thanks for the heads up.
[20:39] <Ryzari> would be easy to use the power though.. just hook up some fans
[20:39] <ali1234> or get a 12V switch
[20:40] <mgottschlag> because there was a time where quite some power supplies wouldn't work with modern boards/CPUs which actually use less than the load from the spec when idle
[20:40] <mgottschlag> MY123: yeah, just saying that a lot of modern supplies do better than that
[20:40] <mgottschlag> I never looked, but given that such problems exist, it should be possible to get more exact specs from manufacturers

[20:47] <Ryzari> yea
[20:47] <Ryzari> they just didn't list it on that page
[20:47] <ali1234> yeah they only list what they stock...
[20:48] <ali1234> anyway point is you can get a power supply for whatever you want... there's no point messing about with ATX power supplies
[20:48] <ali1234> and USB hubs
[20:49] <ali1234> http://www.rapidonline.com/electrical-power/25-50w-mini-desktop-sm-psu-5v-dc-5a-eup-85-2950
[20:49] <shiftplusone> You'd think that ATX power supplies would be much cheaper, since they're mass produced. But yeah, if they require a minimum load, don't want.
[20:49] <ali1234> they are complex though
[20:50] <ali1234> ATX power supplies *can* be cheap... if you don't mind that they are also garbage
[20:50] <ali1234> but you've got all different voltages and sense lines etc
[20:50] <ali1234> just making one voltage is obviously a lot easier
[20:50] <MY123> shiftplusone: The minimal load needed on 12V should be 0,3W if the board is fully Haswell-compatible

[20:52] <ali1234> rapid are pretty good, can't speak for that actual power supply though
[20:52] <shiftplusone> blargh "Stock due in 1-2 months"
[20:52] <ali1234> but the stuff they sell generally does what the datasheet says
[20:52] <ppq> i can recommend the "be quiet! System Power 7 300W", it's cheap and efficient and reliable
[20:52] <shiftplusone> but yeah, that's more than enough to get me going. Thanks.

[21:04] <shiftplusone> and only the cheap ones seem to have voltage sag problems.
[21:04] <ali1234> yeah, thing is phones don't care because they only need 4.2V to charge a li+
[21:04] <ali1234> so they regulate it down anyway
[21:05] <ali1234> i use my nexus 7 charger, it's rated 2A but it dips below 5V at about 800mA
[21:05] <Ryzari> i power mine off this: www.amazon.com/dp/B00C0XZ7R6/ =/
[21:06] <ali1234> most people aren't going to need 2A to power a pi though
[21:06] <ali1234> in a cluster you won't have any peripherals

[21:40] <DoctorD90> no, it was easy. In italy we use usb dongle wifi that its module isnt in raspbian but each time we have to find out new module or we cant use it :)
[21:43] <DoctorD90> shiftplusone, mail sent 15/01/2015 :) about chipset Realtek RTL8188EUS
[21:43] * dreamon (~dreamon@unaffiliated/dreamon) has joined #raspberrypi
[21:43] <shiftplusone> DoctorD90: I've been trying to get the headers package into the repo, which would let you compile the module on the pi pretty easily. As the next step, it would then be a lot easier to add a dkms package for the module as well. At least it seems more sensible than adding extra third party stuff into the kernel (considering we want to move towards upstream, rather than away from it)
[21:44] <shiftplusone> Found the email, thanks.
[21:45] <DoctorD90> ehm...my language barrier xD ... i havent used rpi in this weeks, so my was just a question eh! not an underline of something done or not done ! be clear :)

[21:55] <shiftplusone> DoctorD90: would've been nice if it actually parsed the revision id rather than looked them up.
[21:55] <DoctorD90> parsed revision?? 0o
[21:55] <DoctorD90> do you mean the 0002 - oood and so on?
[21:55] <shiftplusone> the new revision scheme actually has bits which mean stuff rather than arbitrary numbers.

[22:11] <shiftplusone> ali1234: they're not applied to old models to avoid braking compatibility with existing software.
[22:11] <DoctorD90> ali1234, i get it from /proc/cpuinfo
[22:11] <shiftplusone> If it does ever kick in, it would be in the firmware though.

[22:14] <shiftplusone> remember that the revision is actually burned in the OTP, so to change it the firmware would need to override it (which is already does in some cases).

[22:16] <ali1234> i dunno, but it would confuse anything that checks the revision to determine board type, if it's just programmed in to the chip

[23:31] <significance> Also, my power supply (via TP1 and 2) is at 4.63V
[23:32] <abnormal> too low.. get a better one asap
[23:32] <H__> Zoohouse: not sure if i'll the rpi for that, it may be driven by a regular pc. Same for the camera, guide camera, AO system, focuser, anti-dew system etc.

[23:39] <significance> abnormal: I've done a test with a (not Raspbian, but new) os which works on my other RPi (same make, exact same SD card, exact same wall plug, etc.) and still same result...
[23:41] <significance> Just found a plug which gets 5V+ (to the hundreth) - no fix.
[23:41] <NGC3982> H__: According to user 'mahjongg' on the .org forums, section D17 on the RPI automaticly shorts 5V when >6V is applied, to kill the RPI via the polyfuse and protect the onboards.
[23:41] <abnormal> oh, can't do that.. lol.. the kernel was set up for other pi... in most cases it is not wise to take SD card from one pi to another, it's best to start with fresh install on an empty SD card.
[23:41] <NGC3982> H__: Also, i do think that lower-than 4.75V does not really hurt the RPI, but simply makes logic stuff not work properly. Ethernet and such.
[23:41] <significance> I believe there may be an issue with the GPIO - last time it worked, I believe I shorted it - what might I check next?

[23:42] <H__> NGC3982: I'm feeding mine from a 12V voltage step down convertor. Still protected by the circuit. I used this hack -> http://www.instructables.com/id/Solder-USB-power-cable-to-Raspberry-Pi/
[23:42] <NGC3982> H__: So, 4-6V should not kill the RPI. 4.75-5.25V should be nominal. :-)

[23:43] <NGC3982> :D
[23:43] <H__> LOL
[23:43] <NGC3982> Oh, that guide actually refers to D17 by picture.
[23:44] <H__> yes
[23:44] <NGC3982> How quaint.
[23:44] <H__> how so
[23:44] <NGC3982> I have no idea.

[23:45] <significance> Anyone have any last-ditch ideas on how I might be able to diagnose my Pi?
[23:45] <H__> up 11 days, the voltage step down convertor still works
[23:45] <shiftplusone> NGC3982: what? that's legitimate strain relief =P

[23:48] <shiftplusone> I've started using super glue for that purpose. File a bit of the board and cable to make a good surface for the glue and stick it on there. Cover with tape for bonus points. >.>

[23:55] <significance> So sorry to repost - any last ideas what might be wrong? I believe the issue was a GPIO short from way back when (hasn't booted well since) but the power supply is 5V+ perfect, both SD cards work fine on other Raspberry Pi (so it's an on-board issue), and the PWR and ACT leds are solid on. After a long 5min analysis, no physical damage (shorts, breaks, etc.) has been found.

[23:57] <shiftplusone> significance: sorry, I've only skimmed through the scrollback. The issue is that you're getting 4.6v on the test points but you think the power supply and cables are good?

[23:57] <significance> shiftplusone: got it up to 5V+ with a good power supply - the issue is PWR and ACT leds are solid, nothing on display
[23:58] <shiftplusone> that's 5v across tp1 and tp2?

[23:59] <significance> Yep.
[23:59] <shiftplusone> What happens if you unplug the power, hold the sdcard to the board with your thumb to ensure good contact and then power it up again (while still pinching the card to the board)? Pay attention to the green LED.
