[0:00] <cyanide> for changing the display settings, plus if you want to use it separately for your own stuff
[0:00] <cyanide> check this image http://www.buydisplay.com/media/catalog/product/cache/1/image/c577d1203d4a53d9f98182eb6081b1d6/5/_/5_hdmi_vga_video_driver_board_and_800x480_tft_display_lcd_module.jpg
[0:00] <thescatman> is there a way to increase the amps to a usb port? I'm not able to run a hard drive off one of them it seems :/
[0:00] <clever> cyanide: ah
[0:01] <clever> kind of need that when you have so many inputs to select between
[0:01] <clever> and vga/composite need more fine tuning
[0:01] <cyanide> yeah
[0:01] <PovAddict> thescatman: use a powered USB hub
[0:01] <clever> hdmi is just simpler
[0:01] * jkridner (~jkridner@pdpc/supporter/active/jkridner) has joined #raspberrypi
[0:01] <thescatman> I have one but was really needing to go without one :/
[0:02] <thescatman> I guess my only option is to get a 64/128gb micro sd instead
[0:02] <cyanide> thescatman, if you're brave, cut the 5v wire off the usb cable and supply power separately. connect both grounds (pi and source)
[0:02] <cyanide> lol
[0:02] * Viper-7 (~viper7@ppp118-211-220-126.lns20.syd4.internode.on.net) Quit (Ping timeout: 245 seconds)
[0:02] <PovAddict> thescatman: may be chaper to use a 128GB pendrive
[0:02] * Obzy_ (~Obzy@unaffiliated/obzy) Quit (Quit: Obzy_)
[0:02] <thescatman> PovAddict: good idea
[0:03] <thescatman> Any idea of the maximum performance gain of a micro sd in transfer speeds for the pi? like, is there a limit? I've got a high end sandisk extreme pro in it atm but that was for a hummingboard
[0:04] <thescatman> The ultra or lower end class 10 cards would save me some cash
[0:04] <cyanide> the theoretical limit is the spi bus
[0:05] <plugwash> The raspberry pi's SD slot is not SPI
[0:05] <thescatman> i think I read about that, that's the thing that bottlenecks the ethernet and usb speeds right
[0:05] <shiftplusone> the common wisdom is that sequential read/write speeds are irrelevant when it comes to the way sd cards are actually used in devices like the pi, so a class 10 card is mostly a waste of money.
[0:06] <plugwash> AIUI sequential transfer speeds on the Pi are limited by the fact the SD card interface is fixed to 3.3V
[0:06] <clever> i suspect a log based filesystem would take full advantage of sequential writes, but i dont know if anybody has tried one on a pi yet
[0:06] <plugwash> and the higher speed SD modes require lower voltages
[0:06] <cyanide> plugwash, my bad
[0:06] <thescatman> hm... okay
[0:07] <clever> plugwash: i finaly found those soldering photos of my dead-bug work, 4 hours after we ahd talked about it, lol
[0:07] <thescatman> So I should just buy a cheap card then. as I said, the decent one was needed for a different thing so it's not lost
[0:07] <plugwash> what really matters on devices like the pi is random access performance, if random write performance sucks then upgrades will make you tear your hair out
[0:07] <clever> plugwash: https://www.dropbox.com/s/wibapz9znins0cm/PIC_0026.JPG?dl=0
[0:08] <PovAddict> clever: wtf is that
[0:08] * plugwash tends to buy the rpf's branded cards, they aren't too expensive and have decent random write performance
[0:08] <clever> PovAddict: an ssop-28 chip, soldered up dead-bug style
[0:08] <thescatman> plugwash: what would you get then, as a tl;dr? an average relatively cheap micro sd that's roundabouts class 10? they're damn c
[0:08] <thescatman> ah ok
[0:08] <thescatman> bloody lag
[0:08] <shiftplusone> +1 for the official sd cards. Never had any problems with them.
[0:08] <plugwash> iirc they use a samsung OEM microsd card
[0:08] <clever> PovAddict: https://www.dropbox.com/s/k9s2d18awxuq64d/PIC_0031.JPG?dl=0 and this is the same board later on when i got it half working
[0:09] <PovAddict> ok new contest
[0:09] * bulletmark (~bulletmar@ppp118-208-6-27.lns20.bne7.internode.on.net) has joined #raspberrypi
[0:09] <PovAddict> who has the messiest desk here?
[0:10] * clever digs thru photos
[0:10] * mgottschlag (~quassel@reactos/tester/phoenix64) has joined #raspberrypi
[0:10] <clever> PovAddict: https://www.dropbox.com/s/wq0mtr0cmk5hafe/DSCF0002.JPG?dl=0 hows this?
[0:10] <PovAddict> clever's last photo is the first contender
[0:10] <cyanide> i could sleep on that desk
[0:10] <shiftplusone> https://dl.dropboxusercontent.com/u/175702/desk.jpg
[0:10] <PovAddict> ... what commodore is that? :O
[0:11] <clever> shiftplusone: i see you still have your tape drive out
[0:11] <clever> mine is in a box somewhere
[0:11] * SeeThruHead (~STH@TOROON017DW-LP140-04-845489642.dsl.bell.ca) Quit (Ping timeout: 264 seconds)
[0:11] <PovAddict> ah is it just a tape drive?
[0:11] <shiftplusone> yeah
[0:11] <shiftplusone> the c64 isn't in the photo
[0:11] <clever> i dont see the pc itself, but it could be burried
[0:11] <clever> http://gallery.earthtools.ca/index.py/pc's/Photo_082806_001.jpg
[0:11] <clever> much older photo, look at the tower of towers, lol
[0:12] <PovAddict> :D
[0:12] <clever> and just under the desk, you can see my 10mbit HUB!
[0:12] <thescatman> 1 more thing for now - it's possible to clone an sd card from a pi, onto a larger one right? then extend the partition to the full thing (as i'll be swapping out and upgrading the micro sd)
[0:12] <PovAddict> thescatman: yes
[0:12] <clever> thescatman: yep
[0:12] <thescatman> great. cheers!
[0:12] <clever> http://gallery.earthtools.ca/index.py/pc's/Photo_082806_00a.jpg
[0:12] <clever> at this time, i was stripping some old systems for anything potentialy usefull
[0:12] <PovAddict> going the opposite direction is harder
[0:13] <PovAddict> (shrinking partitions)
[0:13] <thescatman> yeah, i know
[0:13] * wiiguy (fake@unaffiliated/wiiguy) Quit (Quit: I just broke my connection, but no worries, we can rebuild it. We have the technology.)
[0:13] <clever> http://gallery.earthtools.ca/index.py/desk/desk%20005.jpg
[0:14] <clever> my server room, the monitor has since been upgraded
[0:14] * Strykar (~wakka@ has joined #raspberrypi
[0:14] <clever> and the pc's changed out a few times
[0:14] * NullMoogleCable (~NullMoogl@cpe-74-74-136-123.rochester.res.rr.com) has joined #raspberrypi
[0:14] <thescatman> Honestly the pi 2 has really made me interested in the pi properly this time... the performance of the pi 1 really put me off. have just been playing quake 3 on it for a couple of hours off a portable battery pack :D
[0:14] <PovAddict> no CRT monitors left in this house :)
[0:14] <PovAddict> we still have CRT TVs though :)
[0:14] <clever> PovAddict: a few in the garage, and 2 crt tv's still in use
[0:15] * bizarro_1 (~bizarro_1@237.Red-83-55-239.dynamicIP.rima-tde.net) Quit (Read error: Connection reset by peer)
[0:16] <thescatman> it's surprising how long the pi 2 can run off a battery actually
[0:16] <imbezol> i just finished running cat 5 and power cables through the rafters to get them over to the top of a bookshelf. got the pi all setup with camera to take a picture every 2 seconds of my poker table. wrote a small script to turn it into a timelapse video of the game. should be fun to see the chips stacks go up and down and the players get eliminated
[0:16] <clever> http://gallery.earthtools.ca/index.py/lipo
[0:16] <clever> graphs from when i ran my pi off a lipo battery
[0:16] <clever> 7 watt hour
[0:17] * bizarro_1 (~bizarro_1@237.Red-83-55-239.dynamicIP.rima-tde.net) has joined #raspberrypi
[0:17] <clever> i also had an i2c lipo charge monitor plugged into the pi, along with snmp support, and was polling it over wifi
[0:17] <cyanide> what is the power consumption of a pi if you dont want to drive a display?
[0:17] <imbezol> now i'm wondering if i should do the same on the second table. could have the video split until it gets down to 1 table and then fullscreen that table
[0:17] <cyanide> just a few gpio pins
[0:17] <cyanide> i'll be connecting an xbee which is about 50mA
[0:17] <thescatman> imbezol: I'm trying to do exactly that for a small project... how did you set it up to take pictures like that? and how much space do they roughly use?
[0:17] <clever> http://gallery.earthtools.ca/index.py/lipo/vcell.png you can get a decent view of the discharge curve here
[0:18] <thescatman> clever: at what point did it turn off / die?
[0:18] <thescatman> like, i guess there's a minimum amperage for it to run on...
[0:18] <clever> thescatman: i think i ran it until it just died, so where the graph just stops
[0:19] <thescatman> ah ok
[0:19] <imbezol> thescatman: the picture taking part is really easy.. it's all built in.. enable your camera first, then just use the raspistill command line util
[0:19] <clever> i was using a boost regulator, so as the voltage dropped, it began to suck more current to keep the pi going
[0:19] <plugwash> a lot of lithium packs have a built in protection circuit
[0:19] <clever> which then made the voltage drop even faster
[0:19] <plugwash> so if the voltage drops to a certain level they cut the load off
[0:19] <clever> plugwash: yep, i'm pretty sure the 2.8v low cutoff in the lipo kicked in before the protection in the boost board
[0:19] <clever> so the boost board protection is useless in my case
[0:19] <thescatman> that makes sense
[0:20] <clever> i have a list of the parts i used somewhere
[0:20] <imbezol> thescatman: then i wrote a small script.. http://imbezol.org/maketl.sh
[0:20] <clever> https://www.sparkfun.com/wish_lists/66243
[0:21] <clever> thescatman: and my figures are in here, 2000mAh lasts 4 hours with it idling on wifi
[0:21] <thescatman> hmm
[0:21] <clever> which would have damaged the pi
[0:21] * duckson (~duckson@vps.duckson.nl) Quit (Quit: ZNC - http://znc.in)
[0:21] <clever> the fuel gauge board was wired into the pi after a slight modification, the vbat was handling i2c pullup
[0:21] <clever> and the boost/charger handled the 5v supply, directly into the gpio header
[0:22] <thescatman> I understand a whole 10% of that
[0:22] * duckson (~duckson@vps.duckson.nl) has joined #raspberrypi
[0:22] <clever> the fuel gauage board was optional, i just wanted to give it some battery level detection
[0:22] * woo2 (~woo2@unaffiliated/woo2) Quit (Ping timeout: 245 seconds)
[0:22] <thescatman> I've been using a 10,000mAh battery, 2 hours usage with quake 3 didn't even dent it
[0:23] <clever> my rough math says that a 6000mAh would run the pi+wifi idling for ~12 hours
[0:23] <thescatman> imbezol: thanks! I'll see how i can modify that to do what I need i to do
[0:23] <clever> and youve got an even bigger battery
[0:23] <PovAddict> does the pi soc change its power usage considerably when idle vs loaded?
[0:24] <PovAddict> I haven't noticed noticeable differences in CPU temperature...
[0:24] <clever> PovAddict: i think so, where did i put the link
[0:24] <clever> PovAddict: http://raspi.tv/2015/raspberry-pi2-power-and-performance-measurement
[0:24] <clever> A+ draws 100mA idle, and ~210mA when recording 1080p video
[0:24] * taza (~taza@unaffiliated/taza) Quit (Ping timeout: 245 seconds)

[0:26] <clever> brb
[0:26] * taza (~taza@unaffiliated/taza) has joined #raspberrypi
[0:26] <imbezol> thescatman: you can adjust the quality of the pictures taken. i put it at 100% because i'm dumping them on a huge NFS share anyways
[0:26] * saline (~irenacob@li629-190.members.linode.com) Quit (Max SendQ exceeded)
[0:26] <imbezol> thescatman: at 100% they're around 2.7 megs each
[0:27] * Encrypt (~Chuck-nor@AMontsouris-553-1-72-10.w92-151.abo.wanadoo.fr) Quit (Quit: Quitte)

[0:28] <djazz> wow, managed to get the adafruit FM transmitter to work on the pi directly connected to GPIO! http://i.imgur.com/gJQCwtc.jpg
[0:29] <djazz> found some incomplete python code on adafruit forum, it lacked the RDS
[0:29] * LostInInaka (~Unknown@unaffiliated/lostininaka) Quit (Ping timeout: 245 seconds)
[0:29] <djazz> so now i can listen to Galaxy News Radio when im home ^~^
[0:29] <clever> back
[0:30] * woo2 (~woo2@unaffiliated/woo2) has joined #raspberrypi
[0:30] * mgottschlag (~quassel@reactos/tester/phoenix64) Quit (Ping timeout: 240 seconds)
[0:31] <clever> PovAddict: the link i pastes also says that the pi2 can be as much as 14x faster, though it depends on your usage
[0:32] * LostInInaka (~Unknown@unaffiliated/lostininaka) has joined #raspberrypi
[0:33] <shiftplusone> djazz, be careful, you probably wouldn't want to leave it running.
[0:34] <djazz> shiftplusone: i got it on lowest power, doesnt get outside house (when listening with fm radio)
[0:34] * Mr_Sheesh (~mr_s@unaffiliated/mr-sheesh/x-0757054) Quit (Ping timeout: 244 seconds)
[0:34] <djazz> better than using the pi directly as fm transmitter, atleast
[0:34] <shiftplusone> Oh, I thought that's what you were doing
[0:34] * crash__ (~crash_@c-e70ce253.7837827--62697410.cust.bredbandsbolaget.se) has joined #raspberrypi
[0:35] <djazz> shiftplusone: nah, dedicated fm transmitter chip
[0:35] <shiftplusone> ah okay, never mind.

[0:35] * Phosie (~Phosie@unaffiliated/phosie) Quit (Quit: Lost terminal)
[0:36] <shiftplusone> ah, cool
[0:36] <shiftplusone> how's the quality?
[0:36] <PovAddict> bah
[0:36] <shiftplusone> and does it go up to 11?
[0:36] <PovAddict> my local electronics shop doesn't even have a website >.>
[0:36] <djazz> shiftplusone: quality is ok, there's a bit of static
[0:37] <aberrant> so
[0:37] <shiftplusone> hm
[0:37] <aberrant> ubuntu core snappy of whatever it’s called is sorta the suck right now
[0:37] <aberrant> s/of/or
[0:37] <djazz> volume isnt that high as other stations
[0:37] * chod (~chod@toy-town.demon.co.uk) Quit (Remote host closed the connection)
[0:37] <djazz> but waay better then PiFM
[0:37] <aberrant> the pi2 is absolutely fast though
[0:37] <aberrant> even with raspbian
[0:37] * llorllale (~llorllale@ has joined #raspberrypi
[0:37] <shiftplusone> aberrant, all the distros were meh when they were first released
[0:37] <aberrant> I got rid of all the xorg / x11 cruft
[0:38] <shiftplusone> it will probably take a while for it to be nice and polished.
[0:38] <aberrant> shiftplusone: yeah, but there are no packages / snaps / whatever they’re called yet
[0:38] <PovAddict> aberrant: from raspbian?
[0:38] <aberrant> PovAddict: yeah
[0:38] <PovAddict> aberrant: did you try an image like minibian?
[0:38] <aberrant> PovAddict: no, I get the official ones and cull them
[0:38] <aberrant> just easier
[0:38] <aberrant> apt-get remove xorg-common x11-common usually does it
[0:38] <shiftplusone> yeah, I don't know how the whole snap thing is supposed to work... I find all this 'cloud' talk very vague and finding useful information in between the buzz words is something I can't be bothered doing >.>
[0:38] <aberrant> then an autoremove
[0:38] <aberrant> then a purge
[0:39] <zproc> anyone tried that Ubuntu/Linaro image?
[0:39] <aberrant> shiftplusone: the thing is that you can’t even change the default password, since root is mounted read only.
[0:39] <shiftplusone> zproc, someone did a comparison on the forum and it comes up as being a little faster than debian and raspbian.
[0:39] <aberrant> you have to remount r/w for any changes to /etc
[0:39] <shiftplusone> aberrant, oh... fun.
[0:39] <PovAddict> wth
[0:39] <aberrant> yeah, it’s weird
[0:39] <aberrant> the idea, I guess, is that you install docker and do all your userlevel stuff there
[0:40] <zproc> shiftplusone: okay thanks, aside from that does it provide anything more?
[0:40] <aberrant> but docker isn’t yet available on arm
[0:40] <aberrant> so you’re SOL
[0:40] * Sir_Pony (~rawr@cpe-174-099-005-078.nc.res.rr.com) Quit (Read error: Connection timed out)
[0:40] <shiftplusone> zproc, no idea. Playing around with it is on the todo list.
[0:40] <aberrant> I’ll stick with raspbian
[0:40] <aberrant> I want to try to build Julia on this thing
[0:41] <zproc> shiftplusone: same here, but i've been procrastinating
[0:41] <PovAddict> the only problem I had with minibian is that it doesn't come with wi-fi stuff by default
[0:41] <aberrant> if that works then I’ll be a happy f*&%ing camper
[0:41] <PovAddict> and I have no physical access to my router atm
[0:41] <shiftplusone> brb
[0:41] <aberrant> ok, time for me to jet. later.

[0:43] <PovAddict> I only have one pi
[0:43] <PovAddict> does that mean I can justify buying a Pi2? :D
[0:43] <zproc> yes :)
[0:43] <PovAddict> my dad challenged me to control LEDs from my iPod touch, I got it done in a few days :D
[0:44] <PovAddict> the native iOS app I wrote still sucks though

[1:02] <djazz> between two
[1:02] <factor> Does raspberry pi have a commandline proxy setup , wich includes script access to proxy?
[1:02] <Giddles> is there some free webspace service like dropbox?
[1:02] <djazz> right now 3 are in use as servers, two too "old", and some model A's i only use for special purposes
[1:03] <Giddles> or knew anyone some?
[1:05] <djazz> rest i use for varios experiments

[1:48] <clever> i have done unencrypted and wep without wpa_supplicant, but wpa_supplicant just makes auto-connecting to several configured networks so much simpler

[1:51] * shiftplusone shrugs
[1:51] <zproc> i can install wpagui so i guess uh
[1:52] <PovAddict> the package name is without underscore
[1:53] <shiftplusone> learning to use apt-cache search would be good.
[1:53] * foobrew (~foobrew@ip68-7-240-112.sd.sd.cox.net) Quit (Quit: leaving)
[1:54] <ali1234> clever: can wpa_supplicant start an access point if there are no known networks in range?
[1:54] <clever> ali1234: nope, need to fully stop wpa_supplicant, and then start hostapd
[1:54] <clever> and then you loose the ability to scan
[1:54] <clever> but some wifi cards/drivers let you run it in 2 modes at once
[1:55] <clever> so it can be both a client and a ap at once
[1:55] <clever> on the same channel though
[1:55] <PovAddict> could build a wifi repeater with that
[1:55] <clever> yeah, but same channel limit will instantly halve your bandwidth
[1:55] <zproc> shiftplusone: i did an apt-cache search
[1:55] <zproc> no luck i guess
[1:55] <shiftplusone> hm
[1:56] <PovAddict> yeah
[1:56] <zproc> but i guess there isn't a module for my wifi dongle so well
[1:56] <PovAddict> zproc: the package is called wpasupplicant
[1:56] <zproc> i understood thanks it's installed PovAddict
[1:56] <zproc> i install wpagui
[1:56] <PovAddict> shiftplusone: the wpasupplicant package doesn't have wpa_supplicant in its description :/
[1:56] <zproc> installed*
[1:56] <shiftplusone> I would've searched for wpa supplicant, not wpa_supplicant
[1:56] <clever> PovAddict: i always break it down to a keyword if i dont get any hits
[1:57] <clever> so search for something that never shows up elsewhere like wpa, or supplicant
[1:57] <PovAddict> shiftplusone: ah
[1:57] <PovAddict> good idea
[1:57] <clever> supplicant will likely have less false hits
[1:57] <clever> i cant think of anything else that has that in the name
[1:58] <zproc> hm i'm used to apt-cache search, it's just that sometimes...
[1:59] <clever> it also searches describe on me, so i usualy pair it up to grep
[1:59] <clever> apt-cache search supplicant | grep wpa | grep supplicant
[1:59] <clever> for example
[1:59] <ali1234> apt-cache search foo | grep foo
[1:59] <ali1234> ^ i wish that this wasn't necessary, but it is
[2:00] <shiftplusone> that doesn't sound right
[2:00] <shiftplusone> but am not currently on linux to play around with it. interesting
[2:00] <PovAddict> if you want to only search the short descriptions, use aptitude search :)
[2:00] <ali1234> it isn't right, it's just the way it is
[2:00] <clever> root@klingon:~# apt-cache search supplicant
[2:01] <clever> dhcpcd-gtk - GTK+ frontend for dhcpcd and wpa_supplicant
[2:01] <clever> barely fits, lol
[2:01] <ali1234> try "apt-cache search foo | grep -v foo" and check out how much irrelevant stuff that usually turns up

[2:02] <benighted> is there a way to update NOOBS with existing images to work on rpi2?
[2:03] <zproc> benighted: you can update Raspbian directly
[2:03] <PovAddict> benighted: what do you mean "to work on rpi2"? they already work
[2:04] <ali1234> zsync would be handy for this
[2:04] <benighted> I have an existing pi sd image (noobs) with raspbian and openelec

[2:06] <zproc> how should i proceed to find info on a module for my Wifi dongle for Linaro? I know nothinig about Linaro. Lsusb, and google for the ID of the dongle etc?

[2:06] <PovAddict> benighted: it won't take full advantage of the hardware though
[2:07] <plugwash> pretty sure an old noobs install won't "just work" on a pi2

[2:08] * chris_99 (~chris_99@unaffiliated/chris-99/x-3062929) Quit (Quit: Ex-Chat)
[2:08] <plugwash> because pi2 needs a new kernel and the problem with noobs is that the recovery partition is never updated. I understand why this design descision was made (seriously reduces the risk of ending up with an unusable recovery) but it's unfortunatley a problem when transferring to new hardware
[2:08] * fengling (~fengling@ Quit (Ping timeout: 246 seconds)
[2:09] <plugwash> it may be possible to manually update the recovery partition by replacing the files with the versions from a new release but I haven't tried this myself
[2:09] <shiftplusone> plugwash, it's just a matter of extracting NOOBS lite onto the recovery partition (without recovery.cmdline)
[2:09] <ali1234> is there any reason why raspbian never unmounts /boot when you do "shutdown -r now"?
[2:10] <ali1234> (and then complains at the next boot up that it wasn't cleanly unmounted)
[2:10] <shiftplusone> ali1234, are you sure that's why it complains. There's a bug which doesn't actually unset the dirty bit on fat partitions when you run fsck, so I suspect that's all it is.

[2:49] * Macuser (~textual@unaffiliated/macuser) has joined #raspberrypi
[2:49] <plugwash> ShorTie, ^^
[2:49] <ShorTie> nop, the regular raspberrypi-bootloader
[2:51] <ShorTie> can't be found at either ox.ac.uk or raspbian.org untill you change to a regular sources.list
[2:52] <plugwash> because it contains a kernel that wasn't built by the raspberry pi foundation not by us, it also doesn't come with a source package and requires some digging to find the source, it's also not immediately clear what compiler it was built with (I suspect it was the compiler in the raspberrypi/tools github repo but i'm not positive, nor is it clear if the source for the compiler in raspberrypi/tools is available anywhere)
[2:52] <ShorTie> ox.ac.uk and raspbian.org have identicle package list
[2:52] <plugwash> and it doesn't have a headers package either
[2:53] <PovAddict> isn't raspbian.org just a redirector to a mirror, one of which can be ox.ac.uk?
[2:53] * fengling (~fengling@ Quit (Ping timeout: 264 seconds)

[2:54] <ShorTie> it's no real big deal i guess, just makes cdebootstrapping a 2 step process is all
[2:55] <plugwash> to summarise it bluntly the raspberry pi foundation's raspberrypi-bootloader package falls far short of the standards for anything I would allow near the main raspbian archive

[2:55] <ShorTie> �k�� ��K��
[2:55] <ShorTie> sounds very resonable
[2:56] <plugwash> the "nokernel" version I ship is not great either but at least it's free of GPL stuff, so concerns about source possiblly not matching up are less serious
[2:58] <ShorTie> if it was able tobe found you could build an image with about 10 lines of code
[2:58] <ShorTie> but not being able to adds another whole process in
[2:59] * plugwash has always used debootstrap on the defaults and then added anything else he wants afterwards
[3:00] <ShorTie> ya, debootstrap doesn't support the --include where cdebootstrap does
[3:01] <ShorTie> cdebootstrap does seems alot better to me

[3:05] <ShorTie> yes i agree PovAddict, that is why i wrote my_raspbian.sh so peeps could build there own images easily
[3:07] <seitensei> Psybur: If you're doing stuff on Linux, GPIO is the same as on the B+. If you're going lower level- the hardware address is different (I think that's what it means).
[3:08] <plugwash> if you are doing stuff through the kernel APIs then it's the same
[3:08] <PovAddict> what kernel APIs? /sys/class/gpio?
[3:09] <plugwash> yes for literal general purpose IO, also various interfaces for specific perhipherals (I2C, SPI etc)
[3:09] <plugwash> if you are doing stuff by mapping from /dev/mem and hitting the registers directly then you have to deal with the changed base address
[3:09] <PovAddict> what does the python library do internally?
[3:09] <plugwash> dunno you'd have to read it's sourcecode
[3:10] <shiftplusone> PovAddict, mmaps /dev/mem
[3:10] <PovAddict> so an old distro with an old RPi.GPIO python library will not work on the Pi2?
[3:10] <shiftplusone> the distro doesn't matter, as long a rpi.gpio is up to date
[3:10] <PovAddict> well old image I meant :)
[3:11] <PovAddict> I need a fun project... preferably one that doesn't require me to buy more things :(
[3:11] <plugwash> you will also need to update the kernel/firmware for pi2 of course
[3:11] <ali1234> do you hve a pi 2?
[3:11] <shiftplusone> I think the same answer still applies... it doesn't matter if the original image is old, as long as it's up to date.
[3:12] <PovAddict> ali1234: I have a Pi 1 model B
[3:12] <ali1234> never mind then...
[3:12] <shiftplusone> *(as long as the install itself is up to date)
[3:13] <Psybur> Im setting up my pi 2 b :D
[3:13] <plugwash> of course "up to date" can be an interesting thing
[3:13] <PovAddict> the only projects I've done with it is control LEDs from an iOS app and share a printer in the network (basically install cups and configure it)
[3:13] <Psybur> I got my arduino running the pingpair_dyn example, currently trying to get the python crap working on the pi for the RF24 lib
[3:13] <plugwash> depending on who built the image and how various things may or may not be managed by packages or may need manual updating
[3:13] <shiftplusone> yeah, that's all a bit unfortunate.

[5:36] <qubitnerd> fstab ?
[5:37] <Psybur> Im going to have a set of voltage dividers on the analog pins of an arduino (four buttons per pin) and the arduino is going to tell a pi which button was pressed. The pi is going to make a web service call to an app that Im going to use to keep track of how my students are doing on tasks I assign
[5:38] <Psybur> So Im thinking about 2-4 students, each with a set of 4 buttons, to one arduino
[5:39] <McBride36> qubitnerd, not sure i want to try that yet
[5:39] <McBride36> i did dmesg and here's what it tells me in regards to mounting [ 3.863869] VFS: Mounted root (ext4 filesystem) readonly on device 179:6.
[5:39] <qubitnerd> McBride36: i meant could you post your fstab
[5:39] <McBride36> ah
[5:39] <Psybur> And the pi will tell the arduino the result and certain led corresponding to a task and state will change
[5:41] <McBride36> qubitnerd, http://puu.sh/fTp5d/de7e15a788.png
[5:41] <qubitnerd> -.-
[5:41] <Psybur> Hmm I only have about 7 digital pins left
[5:41] <Psybur> I wonder how I could use these
[5:41] <qubitnerd> pi isnt connected to the internet i suppose
[5:41] <McBride36> itis, i'm accessing it over ssh now
[5:42] <qubitnerd> well could you paste the entire text
[5:42] <McBride36> also, just assume i'm really dumb about all of this, this is my first arch experience
[5:42] <qubitnerd> well nvm ..
[5:42] <McBride36> that's a puush of the entire fstab
[5:42] <qubitnerd> okay
[5:43] <ShorTie> McBride36, did you recitely update and is there new files in /boot that need to be updated/exchanged ??
[5:44] <McBride36> ShorTie, ran -Syyu today after install

[5:51] <ShorTie> you need to change out cmdline.txt with cmdline.txt.pacnew
[5:51] <qubitnerd> those are to be merged or replaced
[5:51] <ShorTie> do like
[5:52] <ShorTie> cp cmdline.txt cmdline.txt.orig

[5:54] <McBride36> now it's done

[8:00] <McBride36> is the pi operational?
[8:00] <wilornel_> yep!
[8:01] <wilornel_> It's strange though. The pi operates at 3.3V but it can output 5.0V ?
[8:01] <cyanide> does the 5v gpio pin go through a fuse?
[8:01] * qubitnerd (~neutrino@unaffiliated/electron/x-8286743) has joined #raspberrypi
[8:01] <cyanide> wilornel_, the usb input is 5v
[8:01] <wilornel_> Nah I just made it go straight through the LED
[8:01] <cyanide> besides, it could be accomplished using a boost converter
[8:01] <wilornel_> Ah I see
[8:01] <wilornel_> Boost converter would mean "accumulate current" and then send it out, right?
[8:01] <cyanide> so you could do 5v from a 3.3v input regardless, just that in this case it is probably direct
[8:02] <cyanide> http://en.wikipedia.org/wiki/Boost_converter
[8:02] <McBride36> yeah but no reason to do that when you have a 5v pin availible
[8:03] <cyanide> yeah, but his question seemed like he didnt know you could do that. some more useless knowledge :)

[8:10] <SpeedEvil> My existing fridge has issues.
[8:10] <SpeedEvil> And uses too much power.
[8:11] <wilornel_> McBride36: All I know about that led is it is an LED 3R
[8:11] <wilornel_> What does the 3R mean?
[8:11] <SpeedEvil> wilornel_: What sort of LED. What does it look like.
[8:11] <wilornel_> And why did the first LED not explode like that?
[8:11] <wilornel_> It's a red LED
[8:11] <SpeedEvil> What did you do with it.
[8:11] <wilornel_> I connected it to 5Volts and GND...
[8:11] <wilornel_> But!
[8:12] <wilornel_> No I actually connected it in series with a 1/4 Watt resistor
[8:12] <SpeedEvil> Of what value?
[8:12] <wilornel_> At first that seemed to do the trick but then for some reason it exploded
[8:12] <wilornel_> LED 3R
[8:12] <wilornel_> It's red
[8:13] <SpeedEvil> you used a 3 ohm resistor?
[8:13] <McBride36> he didn't specify resistor value
[8:13] <wilornel_> On the bag of resistors it says: R 1/4 - 1
[8:13] <wilornel_> So I think it's a 1/4 Watt resistor
[8:13] <McBride36> what are the colors on the resistor
[8:14] <wilornel_> gold gold blue red
[8:14] <wilornel_> or more like bronze bronze blue red
[8:15] <SpeedEvil> Do you have a multimeter?
[8:15] <wilornel_> Not yet, planning on getting on

[8:17] * qubitnerd (~neutrino@unaffiliated/electron/x-8286743) Quit (Quit: WeeChat 1.1.1)
[8:17] <wilornel_> but it's a very cheap resistor, so I guess it's 260 ohms
[8:18] <SpeedEvil> That would be red blue brown
[8:18] * qubitnerd (~neutrino@unaffiliated/electron/x-8286743) has joined #raspberrypi
[8:18] <McBride36> ^ my guess as well
[8:18] <wilornel_> so 1 resistor is not enough?
[8:18] <wilornel_> I'm trying it again with 2 of those
[8:19] <SpeedEvil> red blue gold gold could be 5% 2.6 ohms
[8:20] * JlRd (~jlrd@ip68-110-113-182.ph.ph.cox.net) Quit (Ping timeout: 252 seconds)

[8:21] <SpeedEvil> black is 1
[8:21] <McBride36> yeah i'm seeing that now with this nifty resistor app

[8:25] <wilornel_> Ach. Restarted the Pi and it still does not output 5Volts.. Did I break it?
[8:25] <wilornel_> Why did it not explode the first time where there were 0 resistors (the led just burned), and when there was 1 resistor, the LED didn't jsut burn, it exploded?
[8:26] <cyanide> what was the point?
[8:26] <wilornel_> Just to see if the GPIO was outputting anything
[8:27] <cyanide> ive never had an led explode on me
[8:27] <SpeedEvil> I strongly recommend you do not do anything involving connecting components until you get a multimeter and understand how to use it

[15:26] <DoctorD90> hi guys! just a little question: someone tells me that rpi, (instead of arduino) hasnt a real clock for signals. What this means? 0o ....it is just a little hole in my comprehension of both :P thx
[15:27] <Sonny_Jim> They might be referring to the lack of hardware clock
[15:27] <Sonny_Jim> Err, I forget the proper name for it
[15:27] <Sonny_Jim> It means it forgets the time after it's powered off
[15:27] <Sonny_Jim> So you have to rely on things like NTP to set the time
[15:28] <Sonny_Jim> RTC?
[15:28] <Bilby> There's no BIOS battery (or equivalent) so powering the pi off means it forgets the time
[15:28] <Bilby> yep
[15:28] <Sonny_Jim> https://www.modmypi.com/rasclock-raspberry-pi-real-time-clock-module
[15:28] <Sonny_Jim> If you don't have any network available, you can use something like this
[15:29] * Xano (~bart@a92136.upc-a.chello.nl) Quit (Quit: Xano)
[15:29] <Bilby> hah, someone was in there the other day asking about keeping time on a non-networked pi, that would have been a good solution. I didn't even think about it
[15:30] <DoctorD90> ah, but this doesnt effect timing in signal output ?
[15:30] <Sonny_Jim> Not really
[15:30] <Sonny_Jim> It has a timing crystal
[15:30] <DoctorD90> if i code a signal output each 20ms, it will output signal every 20ms?
[15:30] <Sonny_Jim> Depending on how you code it, yes
[15:30] <Sonny_Jim> Remember that Linux isn't a realtime OS
[15:30] <DoctorD90> what do yo umean?
[15:30] <Bilby> You're talking about yeah that
[15:31] <Bilby> the RasPi doesn't have a proper PWM output, though it's pretty good at emulating one
[15:31] <Sonny_Jim> 20ms should be fine, it's when you start talking about microseconds is when Linux might not be up to the task, dependg on how you code it
[15:31] <Bilby> DoctorD90 - "realtime OS" means everything moves to the clock (in layman's terms).
[15:32] <Bilby> on the Raspi and most linux systems, background tasks and core processes can pre-empt your running program, so changes may be delayed as the system does other things
[15:32] * davanger (~MacPro@185.Red-79-146-141.dynamicIP.rima-tde.net) has joined #raspberrypi
[15:33] <Sonny_Jim> So the network code might take priority over your code, meaning it delays so you don't get exact timings
[15:33] <Sonny_Jim> But this is true for any non-realtime OS really
[15:33] <Sonny_Jim> And it's only when you start going below millisecond timings when you start running into problems
[15:33] * iamjarvo (~textual@c-68-81-129-125.hsd1.nj.comcast.net) has joined #raspberrypi

[15:34] * Insmell (~Todd@ Quit (Ping timeout: 246 seconds)
[15:34] <DoctorD90> ah! so if i want a millisecond precision, rpi isnt good? rigth? i dont get the real clock parsing, but the OS parsing from clock,?
[15:34] <Sonny_Jim> The RTC is something different, it's for keeping system time
[15:34] * sander^home (~sander@ti0108a400-1668.bb.online.no) Quit (Ping timeout: 255 seconds)
[15:34] <DoctorD90> yes, it was what im was looking for, but that doeasnt what i aimed to :D
[15:35] <DoctorD90> the rtc is just for memory of time
[15:35] <Sonny_Jim> What do you plan to do with the Pi?
[15:35] <DoctorD90> the "realtime os" is what i was aimed to :D
[15:35] <leio> err, can't you run a realtime OS fine on a Pi? In fact, NOOBS has one
[15:35] <DoctorD90> ?? a realtime os??
[15:35] <DoctorD90> like? 0o
[15:35] <Sonny_Jim> Sure you can, but then you start losing then benefits of using Linux. It's a trade off
[15:36] <leio> yes, but I read from the discussiona bove that raspberry doesn't support realtime OS
[15:36] <Sonny_Jim> Well, I phrased it as "Linux isn't a realtime OS", but I get your point
[15:36] <leio> ok, nvm, you were specific about it being about linux, but got that impression with the discussion threads mixed up
[15:37] <Sonny_Jim> Also, bear in mind DoctorD90 that a microsecond is a lot smaller than a millisecond ;-)
[15:37] <leio> anyways, a realtime OS has huge caveats for achieving a very specific purpose you can't do with linux or the likes
[15:37] <Sonny_Jim> In fact I think there are kernel drivers that can do microsecond timings

[15:49] <plugwash> yes
[15:50] <Sonny_Jim> autrilla: I think the original point was so you could offload tasks to that instead of running them on the Pi CPU, but I haven't looked at it that closely
[15:50] <autrilla> But it costs more than a pi
[15:50] <autrilla> you could just buy another pi

[15:57] <davanger> if you want to compile your own packages you need to look into cross compiling
[15:57] <Sonny_Jim> It depends if xorg uses the GPU to hold window contents as textures
[15:58] <day> im not questioning if its the best or not. i just want to try it

[16:57] * polarburn (polar@thebes.openshells.net) Quit (Ping timeout: 245 seconds)
[16:57] <PovAddict> 's/raspberrypi-bootloader\./raspberrypi\/bootloader-nokernel\./'
[16:57] <PovAddict> oh oh
[16:57] <PovAddict> you could also use a different separator
[16:57] <plugwash> DOH thanks for pointing out that my typo didn't have anything to do with what I thought the problem was
[16:58] <PovAddict> 's!raspberrypi-bootloader\.!raspberrypi/bootloader-nokernel\.!' works too iirc
[16:58] <plugwash> I thought the "." was magic and escaped it but I completely missed that I had a "/" where I should have had a "-" in the replacement string
[16:59] <PovAddict> the . in the first part is magic, it means 'any character'
[16:59] <plugwash> so am I escaping it correctly?

[21:20] <clever> ali1234: not sure about SPI, but i believe thats what SMI is for
[21:20] <Twist-> bleki_one: Yeah. And knowing those commands will help you research more effectively.
[21:20] <clever> if i remember correctly, its a 24bit wide external memory interface
[21:20] <Twist-> bleki_one: do you know about 'man pages' yet?

[21:24] <bleki_one> Twist- I dont really need it, but when I tried to explain to my 10yrs old daughter what is pi and what mean remote control it, then I tought that show her that what I type on laptop will be displayed on TV would work best

[21:28] <thescatman_> nice simple way to learn some console commands etc

[21:28] <bleki_one> thescatman_: do you think B+ will manage to run Quake server?
[21:29] <Twist-> McBride36: Heh. I make that argument for unix as a whole.
[21:29] <thescatman_> bleki_one: I reckon it should be able to...
[21:29] <thescatman_> I haven't run quake 3 on the old pi, only on the pi 2. the pi 2 is WAY more powerful though so I don't know
[21:29] <Wec> thescatman_ You could stream it and then open the stream on the Pi

[21:37] <thescatman_> ali1234: How do I close it? :|
[21:37] <ali1234> ctrl-c
[21:37] <ali1234> it draws in an overlay so whatever is behind it, console or X, is still working as normal
[21:38] <thescatman_> oh, I alt+f4'd the overlay a second ago trying to close it lol
[21:38] <thescatman_> console*
[21:38] <clever> alt+f4 switches to tty4
[21:38] <clever> where the app isnt running
[21:38] <clever> alt+f1 to get back to the default one, then ctrl+c
[21:38] <thescatman_> Got it. cheers :)
[21:39] <clever> by default, tty1 thru tty6 have login prompts, and you can switch with alt+f1 thru alt+f6
[21:39] <clever> giving you 6 shells without the use of screen/tmux
[21:39] <clever> tty7 and alt+f7 is usualy xorg
[21:39] <clever> and xorg eats the alt comboes, so you cant leave it with alt+f4 or alt+f1
[21:40] <clever> you have to upgrade to ctrl+alt+f1 thru f6 to escape and get back to console
[21:40] <clever> though ive never tried that on a pi, it should probly work the same as desktop

[21:59] <ali1234> what solution did you use for getting battery voltage and current?
[21:59] <clever> ali1234: it had snmp support, so i could graph the battery over wifi
[22:00] <thescatman_> it's not dangerous to run the pi 2 with 1A input is it
[22:00] <thescatman_> it seems to run as well as on 2A
[22:00] <ali1234> thescatman_: input current is only a maximum rating
[22:00] <clever> ali1234: https://www.sparkfun.com/wish_lists/66243
[22:00] <clever> ali1234: main issue, the i2c battery guage used vbat for i2c pullup
[22:00] <clever> which would have messed with the pi
[22:00] <clever> so i had to cut a trace on the board
[22:00] <cyanide> thescatman_, that is just the maximum current that the source can supply
[22:00] <cyanide> doesn't mean the pi will suck it all in
[22:01] <thescatman_> ah ok
[22:01] <ali1234> clever: so you used the MAX17043... how did you get current?
[22:01] <thescatman_> But I assume the worst that can happen with less than enough power would be a shutdown on load / boot and sd corruption
[22:02] <ali1234> thescatman_: yes. but the pi itself doesn't use more than 1A so it depends what else you have connected
[22:02] <clever> ali1234: no current figures, just voltage and the estimated battery level
[22:02] <ali1234> clever: i want to know current draw as well (and not just an average over time)

[22:06] <clever> and the calibration maxes out at 4.5v
[22:06] <clever> this is a bare avr chip on a breadboard
[22:06] <clever> made it before i got the pi
[22:06] <clever> oh, typo above, meant to say avr
[22:06] <ali1234> oh you meant AVR not pi :)
[22:07] <clever> been awake too long
[22:07] <ali1234> fair enough
[22:07] <clever> 25 hours i think
[22:07] <ali1234> so does my circuit look vaguely reasonable?
[22:07] * PovAddict throws a cushion at clever
[22:07] <clever> ali1234: is there a reason you need to measure ADC things above 3.3?
[22:07] <ali1234> well the battery could be 4.2v
[22:07] <ali1234> but i guess i could use a divider
[22:07] <clever> yep
[22:08] <clever> thats how i'm measuring the 5v rail with the internal ~1.2 reference
[22:08] <ali1234> i never tried to do anything like this before, i am learning as i go
[22:08] <clever> originaly, i was being silly and ran the entire project on supercaps
[22:08] <clever> and i wanted to see how the voltage dropped
[22:08] <clever> the caps have since been removed, the code hasnt
[22:09] <ali1234> if i use the internal reference, what do i do with AVCC?
[22:09] <clever> avcc still has to be tied to vcc, i believe it always has to be there
[22:09] <ali1234> okay
[22:09] <clever> but avcc is present so you can add extra filtering, to keep the analog supply noise free
[22:09] <clever> to keep all the digital logic noise out of the adc
[22:09] <ali1234> i see
[22:09] <ali1234> but it has to bee same voltage as VCC?
[22:10] <clever> i think so
[22:10] <clever> aref is different
[22:10] <ali1234> makes sense
[22:10] <clever> i believe aref will output the internal 1.2v reference if you select that
[22:10] <ali1234> yeah, AREF < AVCC
[22:10] <clever> so you can add an external cap to stabalize it
[22:10] * Talen (~Talen@static-71-255-126-4.cncdnh.fast.myfairpoint.net) has joined #raspberrypi
[22:10] <clever> so aref just needs a cap to gnd, then select internal ref in software
[22:11] * [sk]Ray (~quassel@71-95-197-158.static.mtpk.ca.charter.com) has joined #raspberrypi
[22:11] <clever> motor current will be easy, low side resistor
[22:11] <clever> so if you had say 1 ohm and 1 amp, it would be 1 volt relative to gnd
[22:12] <clever> but you cant use a low side resistor on things like the avr or lipo, because then your gnd is going to get messed up in complex ways
[22:12] <ali1234> why?
[22:12] <ali1234> my booster is not isolated
[22:12] <clever> using the same (but now insane) numbers, the gnd input of the avr would be at 1v relative to gnd
[22:13] <thescatman_> If I were to create some sort of emulation station, I could do it all within raspbian right? You don't need RetroPie or whatever to do that? Or would I be better using something like that with the dedicated retropie etc os
[22:13] <clever> so it will be expecting its 3.3v logic high to be at 4.3 volts
[22:13] <thescatman_> (for the Pi 2)
[22:13] <ali1234> oh right yeah. well you can get 0.05 ohm current sense resistors...
[22:13] <clever> reduces the problem but doesnt solve it fully
[22:13] <clever> thats where high side sensing comes in
[22:13] <clever> so the gnd is at the same level for every part
[22:14] <ali1234> won't the boost regulator just figure it out?
[22:14] <clever> and do the volatge sense for regulation after the current shunt
[22:14] <clever> if you had say boost reg -> 1ohm -> entire project -> boost reg for the negative->prob->pos path
[22:15] <clever> and the boost reg puts out 3.3v, and your drawing 1 amp
[22:15] <clever> thats 1 volt across the resistor
[22:15] <ali1234> hmm i think i see... the AVR will still be at a different GND because it's GND has to be after the resistor
[22:15] <clever> however, the avr is running with gnd at 1v above the bost reg
[22:15] <clever> you would have to ADC a -1v input
[22:16] * Guegs (~Guegs___@207-47-171-38.sktn.hsdb.sasknet.sk.ca) has joined #raspberrypi
[22:16] <ali1234> you'd think there would be a chip for this
[22:16] <ali1234> i've seen voltage sensing ones and current sensing ones but not both
[22:16] <clever> i believe high side sensing solves this
[22:17] <clever> but it adds a large offset
[22:17] <clever> i think you can throw an opamp across the high side resistor, to fix the offset
[22:18] <ali1234> high sensing means put Rs onto the + line and measure the voltage before and after it there?
[22:19] <clever> i think so
[22:19] <clever> but the avr would have to be bypassing that resistor
[22:19] <ali1234> i would anyway i think
[22:19] <clever> which is why i mentioned, lowside the motor itself
[22:19] <clever> the motor doesnt care if its negative input is a few volts above the rest of the system
[22:20] <ali1234> hmm... good stuff
[22:20] <clever> gnd->shunt->motor->fet->++
[22:20] <ali1234> i need to think about this some more
[22:20] <clever> the voltage at the shunk/motor junction tells you current
[22:20] <clever> no need to mess around

[22:21] <clever> so the motor can effectively reverse itself, same path otherwise
[22:21] <clever> do you want current on each, or total?
[22:21] <ali1234> total

[22:24] <ali1234> yeah i am doing :)
[22:24] <clever> all i see is a high side sense resistor and an opamp
[22:24] <clever> exactly what i was guessing would work
[22:24] <ali1234> indeed

[22:26] <ali1234> of course the other concern is that all this circuitry should not use too much power, because it is running off a battery after all

[22:27] <PovAddict> thescatman_: you can do it all within raspbian, but if your emulation needs lots of CPU you probably want to use a distro compiled for the armv7

[22:28] <thescatman_> I thought raspbian compiled itself for armv7 when you first boot on the pi 2
[22:28] <clever> ive heard that you might be able to take stock armv7 debian (not a pi specialized version), and just run that, though youll have to compile/install the userland libs to get 3d and dispmanx
[22:28] <ali1234> thescatman_: no that would take weeks
[22:28] <clever> thescatman_: nope, its running an armv6 userland on an armv7 kernel
[22:28] <thescatman_> oh
[22:28] <thescatman_> ;
[22:28] <clever> start.elf picks the right kernel at boot time
[22:28] <clever> and then everything else is armv6, so it works on both pi's
[22:29] <clever> and you dont have a v7 compiler, so you cant take full advantage of the code without installing a cross-compiler
[22:29] <thescatman_> Well that's slightly annoying... Would you just go straight to an emu OS then? I'd rather have everything on a single card so I can run everything in raspbian but I have spare cards
