[0:00] <techsurvivor> it does gordonDrogon , I though he was trying to repartition for other reasons
[0:00] * Shy (Wewt@pdpc/supporter/professional/shy) Quit ()
[0:00] <gordonDrogon> Geniack, you know how to make life hard for yourself!
[0:00] <techsurvivor> heh
[0:00] <techsurvivor> sorry i misunderstood. the newest released image has the setup tool
[0:01] <gordonDrogon> always handy to know how to do extra fiddling anyway :)
[0:01] <techsurvivor> yeah, i like gparted a lot for other stuff, kind of like a swiss army knife
[0:02] <gordonDrogon> I've got a bootable CD with it on, but I've only used it once..
[0:02] <gordonDrogon> anyway, zed time here..
[0:02] <techsurvivor> i have it on my two linux boxes, along with the card r/w
[0:02] <techsurvivor> adios

[0:13] * charolastra (~quassel@213-33-12-105.adsl.highway.telekom.at) has joined #raspberrypi
[0:13] * PiBot sets mode +v charolastra
[0:15] <charolastra> why can i power the Pi over the USB ports when they are supposed to have 140mA fuses? are they one way only?
[0:16] <steve_rox> i think thats 140ma power out its own usb ports
[0:16] <nid0> "power the pi" as in the power light comes on, or it actually boots?
[0:17] <charolastra> i think it boots
[0:17] <nid0> try it
[0:18] <TheBrayn> do I have to pull the whole repo here to compile the kernel? https://github.com/raspberrypi/linux
[0:18] <Ionic`> I remember your nick
[0:18] <Ionic`> Dunno where from, though
[0:18] * C-M (~c_m@wikimedia/C-M) Quit (Quit: Computer has gone to sleep.)
[0:19] * roivas (~scott@97.83.0.56) has joined #raspberrypi
[0:19] * PiBot sets mode +v roivas
[0:19] <nid0> restricting it to --depth 1 will save you a fair bit of time/space
[0:21] <TheBrayn> is there no .config file?
[0:21] * dirty_d (~andrew@c-76-118-112-146.hsd1.ma.comcast.net) has joined #raspberrypi
[0:21] * PiBot sets mode +v dirty_d
[0:21] <nid0> just copy your running config
[0:22] <TheBrayn> which config?
[0:22] <TheBrayn> I won't use the one from my desktop pc
[0:22] <nid0> zcat /proc/config.gz > .config
[0:22] <TheBrayn> lol
[0:22] <nid0> ?
[0:22] <TheBrayn> It's not configured for usage on the rpi
[0:22] <nid0> copy the running config on your pi...
[0:22] <techsurvivor> TheBrayn: you run that on the pi
[0:23] <TheBrayn> so?
[0:23] <techsurvivor> it gives you a .config file :P
[0:23] <dirty_d> your rpi is an rpi
[0:23] <techsurvivor> like nid0 pointed out
[0:23] <Ionic`> zcat ...
[0:23] * markbook (~markllama@pool-74-104-180-140.bstnma.fios.verizon.net) has joined #raspberrypi
[0:23] * PiBot sets mode +v markbook
[0:23] <Ionic`> gunzip -c /proc/config.gz > .config!
[0:23] <Ionic`> useless use of cat
[0:23] <TheBrayn> the pi is not running and I won't run it until the system is installed
[0:23] <techsurvivor> heh
[0:24] <techsurvivor> well down under arch is a config... let me dig it's in there, i built it :P
[0:24] <dirty_d> you can extract the config from a compiled kernel
[0:24] <nid0> well, if you're gonna needlessly make things hard for yourself, its gonna be more complicated
[0:24] <techsurvivor> bcmrpi_cutdown_defconfig
[0:24] <techsurvivor> look under arch for that as a starting point
[0:24] <Mrgoose2> does a class4 vs class10 sd card make a big difference in performance?
[0:25] <TheBrayn> techsurvivor: thanks
[0:25] <TheBrayn> I apreciate people who know what they are talking about
[0:25] * Milos|Netbook (~Milos@pdpc/supporter/student/milos) Quit (Ping timeout: 260 seconds)
[0:26] <techsurvivor> arch/arm/configs/bcmrpi_cutdown_defconfig
[0:26] <techsurvivor> you know how to do oldconfig and all that, right?
[0:26] <TheBrayn> yes I do
[0:26] <techsurvivor> okie doke
[0:26] <techsurvivor> bootc has a nice guide somewhere
[0:26] <techsurvivor> i think it was him
[0:27] * QA94|Fire (~chatzilla@adsl-074-184-089-183.sip.asm.bellsouth.net) Quit (Quit: ChatZilla 0.9.88.2 [Firefox 14.0.1/20120713134347])

[0:28] * nils_2 (~nils_2@unaffiliated/nils-2/x-2480262) Quit (Quit: WeeChat 0.3.9-dev)
[0:28] <techsurvivor> the way i did it (and there may be an easier way) was to 1. build the kernel 2. copy it over to the rpi over the old kernel.img 3. while still running run sshfs and mount your build machine's directory 4. pop into that mount and run make modules_install
[0:28] <techsurvivor> then reboot
[0:28] * Nik_89 (~nniro@unaffiliated/nniro) has left #raspberrypi
[0:29] * Oldboy (myircshell@grid.sh3lls.net) Quit (Read error: Connection reset by peer)
[0:29] <TheBrayn> I'm compiling the kernel on my desktop using crossdev
[0:29] <techsurvivor> i did too, on a linux machine, sshfs makes it easy to copy all your module files over though. but there are other ways
[0:30] * iama_walrus (~iama_walr@46.246.116.248) has joined #raspberrypi
[0:30] * PiBot sets mode +v iama_walrus
[0:30] <techsurvivor> anyway, best of luck
[0:30] <TheBrayn> thanks
[0:31] <techsurvivor> i basically followed this http://elinux.org/RPi_Kernel_Compilation
[0:31] <iama_walrus> I keep seeing things like "GPIO.setmode(GPIO.BCM)" in documentation. Does anyone know what "BCM mode" is supposed to be?
[0:32] <dirty_d> iama_walrus, nope, thats just a regular gpio pin?
[0:33] <Mrgoose2> does a class4 vs class10 sd card make a big difference in performance?
[0:33] <dirty_d> Mrgoose2, yea
[0:33] <dirty_d> i havent personally witnessed it though
[0:33] <Mrgoose2> oh
[0:33] <Mrgoose2> so for xbmc class10 is definitely recommended i assume
[0:34] <iama_walrus> dirty_d: I don't believe the function acts on any specific pin. Here's an example of it being used: http://pypi.python.org/pypi/RPi.GPIO/0.3.1a
[0:34] <dirty_d> yea id use class10
[0:34] <dirty_d> iama_walrus, oh it changes hte pin numberinch scheme
[0:34] <dirty_d> spelling fail
[0:35] <techsurvivor> you guys using wiring-pi for gpio?
[0:35] <dirty_d> iama_walrus, BCM mode uses the actual chips numbering
[0:35] <techsurvivor> that may be my next foray now that I have the camera stream working
[0:35] <dirty_d> BOARD uses the headers pin numbers
[0:36] <dirty_d> techsurvivor, what kinda camera?
[0:36] <techsurvivor> some offbrand venus 2.0 or something, i can track it down if you like
[0:36] <iama_walrus> dirty_d: Oic. Thanks.
[0:36] <techsurvivor> it works pretty well at 320x240 15fps
[0:37] <techsurvivor> that's all i need, it's pretty jerk at 640x480
[0:37] <techsurvivor> jerky
[0:37] <Geniack> techsurvivor: gparted worked :) i am moving back my files right now, if it works, you'll get a free beer
[0:37] <dirty_d> techsurvivor, usb though?
[0:37] <techsurvivor> glad I could help
[0:37] <techsurvivor> yeah
[0:37] <dirty_d> i tried one and the fps was low like that too
[0:37] <t7> i need more ramz
[0:37] <techsurvivor> it's just a generic uvc
[0:37] <techsurvivor> t7 have you tried the ram split?
[0:37] <dirty_d> you wouldnt think something as simple as a webcam would be that hard to get a high framerate on
[0:38] <t7> i need like 512
[0:38] <t7> for bitcoind
[0:38] <techsurvivor> ah. shouldn't be too hard to solder in another 256MB :P
[0:38] <ReggieUK> easy to solder, hard to sauce
[0:39] <techsurvivor> heh
[0:39] <ReggieUK> if kids can reball a ps3 with a paint stripper, we can do a pi ram chip
[0:39] <dirty_d> crap, updated kernel, no more rpi
[0:39] <techsurvivor> all you need is a toaster oven and some patience
[0:39] * heathkid (~heathkid@unaffiliated/heathkid) Quit ()
[0:40] <dirty_d> my tv is broken too, crap
[0:40] <t7> where is the ram on here?
[0:40] <ReggieUK> I was going to use a hot-air station if I ever find a 512MB pop chip for sale
[0:40] <ReggieUK> its the chip between the hdmi and composite connectors
[0:41] <ReggieUK> and it's soldered to the top of the cpu
[0:41] <t7> RG2?
[0:41] <t7> oh
[0:41] <ReggieUK> there's only one big chip between the hdmi and composite :)
[0:41] <ReggieUK> well, 2 but one sits on top of the other
[0:42] <t7> ah
[0:42] <t7> so i cant see it
[0:42] <dirty_d> you can
[0:42] <t7> i thought it was cpu
[0:43] <techsurvivor> i like the piggy back chip idea, didn't know about that technique before raspi
[0:43] <techsurvivor> i guess it only works on chips that don't get very hot
[0:43] <ReggieUK> not that keen on it myself
[0:43] <techsurvivor> ram can be pretty sensitive to temperature
[0:43] <techsurvivor> shoudl be fine on low power chips
[0:44] <techsurvivor> hard to hack on though
[0:44] <ReggieUK> mainly because it's not a package we can lift from elsewhere (I don't think?)
[0:44] <techsurvivor> yes
[0:44] <ReggieUK> otherwise we'd all be walking round with 512mb pi by now
[0:44] <ReggieUK> well, I would, not sure about you lot :D
[0:45] <dirty_d> my desk is a huuuge mess
[0:45] <techsurvivor> i know people who could probably pop a regular balled memory off, i don't know about this piggy back chip though, it's probably epoxyied on or something to start
[0:45] <dirty_d> i cant find my sdcard usb thingy
[0:45] <t7> someone make a dd3 to silly piggyback chip adapter
[0:45] <techsurvivor> ithink they had something about it in the release notes
[0:45] <t7> ddr3*
[0:45] <techsurvivor> er release presentation
[0:45] <ReggieUK> don't see why it should be expoxied
[0:46] <ReggieUK> I hope it's not
[0:46] <techsurvivor> just a guess
[0:46] <ReggieUK> I've just 'discovered' something with ssh (probably obvious to those that use it)
[0:47] <ReggieUK> I can run stuff that needs X to display
[0:47] * kn1000 (b0ff4f00@gateway/web/freenode/ip.176.255.79.0) has joined #raspberrypi
[0:47] * PiBot sets mode +v kn1000
[0:47] <sam> like ssh -X foo or like ssh 'DISPLAY=:0 foo'?
[0:48] <dirty_d> ReggieUK, yea neat huh?
[0:48] <kn1000> Will the raspberry pi run on low voltages such as 4v?
[0:48] <nid0> no
[0:48] <kn1000> then either my multimeter is crap or something is seriously wrong here
[0:48] <ReggieUK> sam, not even that ssh user@IP ADDRESS
[0:48] <kn1000> because reading voltage off my rpi and it's apparantly around 4.1v and it's been perfectly stable
[0:48] <ReggieUK> and then login, don't startx on the pi, just do something like:
[0:49] <ReggieUK> leafpad somefile.txt
[0:49] <ReggieUK> and up pops leafpad on my host PC
[0:49] <kn1000> I'm using a 3 amp usb hub that's powering the pi and an external hard drive
[0:49] <t7> kn1000: run a while(1) ;
[0:49] <ReggieUK> did not expect that at all
[0:49] <kn1000> t7: what will that do?
[0:49] <t7> stress the cpu
[0:49] <kn1000> ah right
[0:49] <kn1000> I've been stressing it pretty hard with torrents
[0:49] <ReggieUK> I'm having problems with my webcam
[0:50] <ReggieUK> it will only display at 160x120
[0:50] <techsurvivor> try guvcview ?
[0:50] * w0m (~wom@199.19.225.128) Quit (Ping timeout: 246 seconds)
[0:50] * Milos|Netbook (~Milos@pdpc/supporter/student/milos) Quit (Ping timeout: 260 seconds)
[0:51] <techsurvivor> that worked best for me when initially playing with it so I could get it streaming
[0:51] <kn1000> t7: running while true; do true; done on the processor
[0:51] * MaxLeMilian (~MaxLeMili@koln-5d81255c.pool.mediaWays.net) Quit (Quit: This computer has gone to sleep)
[0:51] <ReggieUK> I am trying guvcview
[0:51] <techsurvivor> oh :(
[0:52] <ReggieUK> that's how I discovered it was working at 160x120
[0:52] <kn1000> yep 100% cpu load, machine feels a little more laggy but still stable as far as I can tell
[0:52] <techsurvivor> i had a really cheap camera that gave the rpi nothing but fits
[0:52] <kn1000> let's read the voltages
[0:52] <ReggieUK> everything else tries to do 320x240 etc. as default
[0:52] <techsurvivor> ah
[0:52] <techsurvivor> that's what mine was using as well
[0:52] <ReggieUK> well, this isn't a particularly cheap camera (it's old but never cheap)
[0:52] <techsurvivor> it even works (slowly) at 640x480
[0:52] <kn1000> 4.14v,,,hmnnn
[0:52] <t7> is there a way to get the version that apt-get will install for a package?
[0:52] <ReggieUK> but the drivers work rock solid on a desktop pc
[0:53] <techsurvivor> hmmm, so did my cheap one lol
[0:53] <techsurvivor> it was throwing out tons of kernel messages though, i just switched cameras
[0:53] <ReggieUK> not an option for the project i want to use it in
[0:53] <techsurvivor> well I have no fixes, just letting you know I had a camera that had problems too, even though it was supposed to be UVC compliant
[0:54] <kn1000> well that's a little strange, removed by far the biggest load which is the usb HDD, and the voltage is still reading 4.14 - doesn't appear to be causing problems i'm just curious
[0:54] <kn1000> probably this cheap multimeter
[0:54] <techsurvivor> 4.14? it shouldn't even be working that's way low, you sure your voltmeter is calibrated?
[0:54] <kn1000> I'mma be honest and say I've only ever used a multimeter once in my life and that's now
[0:55] <kn1000> got it set to 20v, it seems to read aa batteries at about 1.5v
[0:55] <techsurvivor> is it analog or digital?
[0:55] <kn1000> digital
[0:55] <techsurvivor> on dc?
[0:55] <kn1000> DCV so I'd assume so
[0:55] * jthunder (~jthunder@174.3.126.51) has joined #raspberrypi
[0:55] <techsurvivor> with right range (if not auto leveling)
[0:55] * PiBot sets mode +v jthunder
[0:55] <kn1000> it's this thing
[0:55] <kn1000> http://www.hobby-hour.com/electronics/dt830b-digital-multimeter.php
[0:56] <techsurvivor> hmmm i don't think an rpi can work at 4.14V. that doesn't sound right at all
[0:56] <kn1000> exactly
[0:56] <techsurvivor> i think you have meter issues :)
[0:56] <IT_Sean> 5v, minimum 700mA
[0:56] <kn1000> probably, any advice?
[0:56] <kn1000> I'm on 5v 3A
[0:56] <techsurvivor> test it on a known voltage?
[0:56] <kn1000> hmn, I don't trust any power supplies anymore xD
[0:57] <kn1000> safe to test on my PC's molex pins?
[0:57] <techsurvivor> like a 9v battery under load ?
[0:57] <kn1000> those are rock steady thanks to an awesome psu
[0:57] <techsurvivor> a 9v will read about 10V without being loaded, most batteries will read high without a load
[0:58] <techsurvivor> sure, if you can get to the pins, make sure it's loaded on a motherboard or something.
[0:58] <kn1000> yeah this current pc lulz
[0:58] <kn1000> well actually
[0:58] <kn1000> will a laptops usb ports put out close to 5v under no load?
[0:58] <techsurvivor> should get 5, 12, 3.3 at least on that
[0:58] <techsurvivor> kn1000: i haven't tried :(
[0:59] <techsurvivor> i bet it will read a little high though, unless you have a lab supply voltage readings are usually a little high without a load
[0:59] <t7> volts / amps = ohms
[0:59] <t7> thats the extent of my leccy knowledge
[0:59] <techsurvivor> heh
[0:59] <t7> i need spell check
[0:59] <techsurvivor> that works for DC ;)
[0:59] <kn1000> reading 4.93V on my laptops usb ports
[1:00] <techsurvivor> it gets more complicated on AC
[1:00] <kn1000> gotta RMS it for AC ;D
[1:00] <kn1000> a level physics ftw
[1:00] <techsurvivor> then that 4.14 just sounds weird
[1:00] <kn1000> hmn
[1:00] <kn1000> lemme test directly from the hub
[1:00] <techsurvivor> i don't know, you sure you hitting the right testpoints?
[1:00] <kn1000> possibly crap cabling
[1:00] <kn1000> yeptp1 and tp2?
[1:01] <techsurvivor> that 4.93 sounds reasonable, but the rpi that's just weird
[1:01] <mru> techsurvivor: ohms law works just fine for ac with resistive loads
[1:01] <mru> with reactive loads it gets a little more complex
[1:02] <mru> you just need to use the e^jw representation and proceed normally
[1:02] * MycoRunner (~brady@74.66.249.170) has joined #raspberrypi
[1:02] * PiBot sets mode +v MycoRunner
[1:03] <techsurvivor> mru: i'm an EE i'm well aware of how reactive loads work :)
[1:03] <mru> ok
[1:03] <techsurvivor> it's this programming stuff that gives me fits ;)
[1:03] <techsurvivor> doesn't help that I'm self taught
[1:03] * markbook (~markllama@pool-74-104-180-140.bstnma.fios.verizon.net) Quit (Ping timeout: 246 seconds)
[1:04] <techsurvivor> or maybe it does, who knows. I love it all nonetheless, embedded systems are awesome
[1:05] <t7> i are hardcore programmerz
[1:05] <kn1000> and yet directly at the hub with no load I'm getting 5.13v
[1:05] <kn1000> if this is crappy cabling I'm going to rage
[1:06] <kn1000> techsurvivor: reckon you could lose almost 1.3v to cabling?
[1:07] <techsurvivor> i doubt it. i don't even see how the rpi could function at 4.14 V that's waaaaay out of spec
[1:07] <IT_Sean> how crap are the cables?
[1:07] <kn1000> with a rpi size load on the hub the voltage dropped on the hub to about 5.06v
[1:08] <techsurvivor> maybe I'm missing something, is the rpi booting? if not ignore me, i thought you had a working system at 4.14 (on tp2->tp1 measurement)

[1:09] <kn1000> yep was booting fine earlier although now it's not
[1:09] <kn1000> reading 3.9v on the pi testpoint
[1:10] <techsurvivor> ah so it's not working... i bet before you had > 4.8V
[1:10] * Zetro (~Zetro@zetro.xen.prgmr.com) Quit (Remote host closed the connection)
[1:10] <techsurvivor> something might be damaged, take everything off the rpi and measure your test points, if you haven't already
[1:11] <MasterGeek> sounds like the power supply is degrading the longer you use it the hotter its getting
[1:11] <techsurvivor> hook the rpi up to your laptop or computer and bypass the power supply, and check your TP's
[1:11] <kn1000> yep has to be cheap cabling
[1:11] <kn1000> jesus christ
[1:11] <kn1000> get this
[1:12] * datagutt (~datagutt@unaffiliated/datagutt) Quit (Quit: Computer has gone to sleep.)
[1:12] <techsurvivor> might have an almost broken power wire (ground or +5v)
[1:13] <kn1000> on a 3 meter long rather high guage microusb cable I read about 4.8v at the test points
[1:13] <kn1000> on some shitty free microusb cable that came with this hub
[1:13] <kn1000> less than 3.5v
[1:13] <techsurvivor> hahah
[1:13] <techsurvivor> you have a bad connection
[1:13] <techsurvivor> did you try the other cable? does it look fine now?
[1:14] <mru> is that the hardware equivalent of a memory leak?
[1:14] * Timmmaaaayyy (~Timmmaaaa@cpe-74-73-185-27.nyc.res.rr.com) has joined #raspberrypi

[1:15] <kn1000> techsurvivor: yep further testing reveals ultracrap cable
[1:16] <techsurvivor> maybe not all cables are built equally, now you have to go buy Monster cables :)
[1:16] <kn1000> which I am now salvaging for the microusb slot and I shall solder some higher quality stuff on there
[1:16] <mru> 99.9% pure oxygen-free copper
[1:16] <kn1000> gonna solder some higher gauge stuff on there, only a short distance <5cm needed
[1:16] <dirty_d> hmm
[1:17] <techsurvivor> well don't go nuts, i've seen very very few bad usb cable over the past 12 years or so i've been doing this stuff heh

[1:21] <IT_Sean> 20 ohms?
[1:21] <IT_Sean> that seems slightly high-ish, no?
[1:21] <mru> my favourite is forgetting the meter isn't auto-scaling, not noticing it's set to 200 uA, and connecting it to the mains :)

[1:23] <kn1000> haroldp: I'm on a 3A supply to a hub and it's great

[1:28] <kn1000> fake chinese caps or missing caps, tiny coils, no ac filtering, tiny or overly large heatsinks, 4 diode treatment rather than rectifier bridge
[1:28] <kn1000> etc
[1:28] <mru> uhm, a rectifier bridge is 4 diodoes...
[1:28] <mru> -o
[1:29] <kn1000> is it?
[1:29] <techsurvivor> you can often tell the bad electrolytics by looking for a bulging cap http://www.capacitorlab.com/visible-failures/pic001.htm
[1:29] <techsurvivor> it can be 1 diode :)
[1:29] <dirty_d> kn1000, yup
[1:29] <techsurvivor> but yeah i guess if it's a bridge
[1:29] <kn1000> fair enough,
[1:29] <techsurvivor> 4 is the standard :) and fun to make

[1:30] <dirty_d> i used one of those to make a hot plate powered smoker
[1:30] <techsurvivor> i love all the electronics destruction videos on youtube
[1:30] <kn1000> was a damn interesting article and I've read probably 60+ of the psu reviews on that site, even though I don't need one
[1:30] <kn1000> lol
[1:30] <dirty_d> 120vac was too muhc, so it got 120vac half-wave
[1:30] <kn1000> guy just places the rated load on the psu via a sunmoon load testor
[1:31] <kn1000> tester* and then tracks the voltage leaving it
[1:31] <mru> the interesting thing is often how a psu reacts to sudden changes in load

[1:36] <mru> might work
[1:36] <ziltro2> Apparently you can weld with high voltage. :)
[1:37] <ziltro2> I suspect it might cause... issues.
[1:37] <dirty_d> i dunno if i believe that
[1:37] <mru> that's how arc welders work
[1:37] <techsurvivor> seems legit
[1:37] <dirty_d> mru, theyre low voltage
[1:37] <mru> high enough to get an arc
[1:37] <dirty_d> 48V
[1:37] <mranostay> dirty_d: low?
[1:37] <ziltro2> But the transformer could provide a lot of current.
[1:37] <dirty_d> probably 24 while welding
[1:37] <ziltro2> Especially if un-fused...
[1:37] <kn1000> wait a sec
[1:37] <techsurvivor> that's a big reason why india's power grid has been failing too, heh almost 50% of the load is just randome people freeloading on the system
[1:37] <kn1000> how much of a voltage loss occurs due to the polyfuses?
[1:38] <techsurvivor> "i think i'll just hook in, unmetered, right about here"
[1:38] <dirty_d> mranostay, yup, you cna make a very powerful arc welder with 3 car batteries
[1:38] <dirty_d> too powerful actually
[1:38] <IT_Sean> heh
[1:38] <ziltro2> Even more powerful with three cars.
[1:38] <techsurvivor> there are youtube videos of that dirty_d
[1:38] <dirty_d> techsurvivor, ive done it
[1:38] <dirty_d> to weld a trailer my welder couldnt reach
[1:38] <dirty_d> came out like crap
[1:38] <kn1000> btw thanks guys
[1:39] <dirty_d> i probably had like 250A on a 3/32" rod
[1:39] <techsurvivor> ah awesome, i saw a guy doing it on youtube. i don't recall the quality o fthe weld
[1:39] <kn1000> not strictly rpi related but still damn interesting
[1:39] <mru> dirty_d: how did you get the arc started?
[1:39] <dirty_d> mru, same way as on a welder, you just scratch the rod
[1:40] <dirty_d> mru, 36V is more than enough to start a high current arc
[1:40] <IT_Sean> talking about emergency arc welding? With a rod & a truck battery?
[1:40] <IT_Sean> It can be done, but, it's a shit weld. Better than no weld at all though, when you have no other choice.
[1:41] <dirty_d> IT_Sean, yea, its only bad because you have no current control

[1:41] <ReggieUK> IT_Sean, language!
[1:41] <IT_Sean> sorry ReggieUK!!!
[1:41] <IT_Sean> :(
[1:41] <ziltro2> Or AC and a coil?
[1:41] <dirty_d> ziltro2, on an arc welder its some kinda variable transformer
[1:41] <ReggieUK> GOOD MANN!!!! ;)
[1:42] <ziltro2> Ah like a variac?
[1:42] <kn1000> oooh
[1:42] <dirty_d> sorta, but in discrete steps i guess
[1:42] <kn1000> does anyone know if the testpoints are wired behind the polyfuses
[1:42] <mru> a constant current regulator is simple in principle
[1:42] <dirty_d> in more modern welders its with transistor switching
[1:42] <kn1000> because that _may_ account for the .3ish v loss
[1:42] <mru> building one capable of very high currents is a bit trickier of course
[1:42] <dirty_d> mru, exactly
[1:43] <ziltro2> Mmm I like the idea of high current transistors.
[1:43] <ziltro2> Not valves then?
[1:43] <ziltro2> Or are they too high voltage?
[1:43] <dirty_d> ziltro2, ived used those for a motor controller for an electric bike
[1:43] <dirty_d> 140A supposedly
[1:43] <ziltro2> Big FETs?
[1:43] <dirty_d> but limited by the package leads to 75A or something
[1:43] <dirty_d> mosfets yea
[1:43] <dirty_d> theyre expensive though, and it hurts your feeling if they blow
[1:44] <ziltro2> I'll want something like that for my electric car. If it ever happens.

[3:47] <bitplane> Hi all, just plugging my raspberry pi in for the first time and not getting anything on the screen. not sure what to expect
[3:48] <bitplane> also my sd card doesn't show anything in gparted
[3:49] <PhotoJim> sounds like you miswrote the image, maybe. or didn't write it to where you think you did.
[3:49] <yehnan> does the OK led on rpi board flashing?
[3:49] <bitplane> no, I just get a red light
[3:50] <bitplane> is anything supposed to happen if I boot without the sd card?
[3:50] <yehnan> bitplane: agree with PhotoJim. I think you should confirm "writing image file successfully to the sd card" first.
[3:50] <yehnan> bitplane: only PWR led will be on. nothing else.
[3:51] <yehnan> bitplane: what image file do you use? what host OS are you using now? what image file writer software are you using?
[3:51] <bitplane> okay, I guess I'll start by verifying the IMG file and work my way from there, thanks :)
[3:51] <bitplane> I'm in Ubuntu and used dd

[3:54] <bitplane> yeah the debian one
[3:54] <Ionic`> maicod: yeah
[3:55] <maicod> ionic: Hi :)
[3:56] <yehnan> bitplane: check if your sd card is on the working card list http://elinux.org/RPi_VerifiedPeripherals#SD_cards
[3:56] <maicod> ionic: I haven't yet tested the SDcards ID etc. but I will try in maybe an hour or so. I've been busy with other things and quite tired :)
[3:56] <bitplane> parted shows the mmc/sd block device to have 4mb unallocated followed by 7.40GiB of unknown
[3:57] <yehnan> bitplane: if your sd card is on the not-working list, doesn't necessarily mean the card is bad....because the list is a bit outdated.
[3:57] <Ionic`> ok
[3:57] <yehnan> bitplane: that's ok
[3:57] <techsurvivor> what command did you type to write the image?
[3:57] <maicod> ionic: one thing I did make was this :) http://s1152.photobucket.com/albums/p499/maicod/?action=view&current=IMG_3564.jpg#!oZZ1QQcurrentZZhttp%3A%2F%2Fs1152.photobucket.com%2Falbums%2Fp499%2Fmaicod%2F%3Faction%3Dview%26current%3DIMG_3564.jpg

[3:58] <bitplane> sudo dd bs=1M if=2012-07-15-wheezy-raspbian.img of=/dev/mmcblk0p1
[3:58] <techsurvivor> you did that on what system?
[3:59] <bitplane> oh... have a confused a partition for a device?
[3:59] <bitplane> Ubuntu 12.04
[3:59] <techsurvivor> should that 1 be on the end ?
[3:59] <techsurvivor> possibly, I didn't do it on debian that is a common problem though
[4:00] <techsurvivor> like for example writing to /dev/sdc1 instead of /dev/sdc would be an issue :)
[4:00] <techsurvivor> what does /proc/partitions show?
[4:00] <bitplane> duh yeah I've written to partition 1!
[4:00] <maicod> ionic: u've seen the pics?
[4:00] <Ionic`> yeah
[4:00] <techsurvivor> don't use a partition number is what I'm getting at
[4:00] <maicod> heehhe LOL
[4:00] <maicod> cool eh :)
[4:00] <bitplane> thanks :)
[4:00] <PhotoJim> yes, write to /dev/mmcblk0
[4:01] <PhotoJim> that's the "top" of the device
[4:01] <bitplane> doing that now :)
[4:01] <techsurvivor> it will probably work now
[4:01] <bitplane> no wonder there was a 4mb space on the thing and gparted couldn't read it
[4:01] <bitplane> must have been old bootloader from my sheevaplug
[4:01] <techsurvivor> it's a little tricky
[4:01] <yehnan> bitplane: congratulations. :)
[4:02] <bitplane> thanks guys, needed that sanity check.. it's 3am here

[4:03] <bitplane> I'm jealous of your lego, my parents gave mine away many many years ago
[4:04] <maicod> bitplane: I lost mine too and got new ones recently
[4:04] <maicod> it was 450 pieces for 14 euros
[4:04] <bitplane> it was mostly an accumulated collection from other family members who grew up and handed them down, so it's only fair I spose
[4:04] <bitplane> had enough to build a small city!
[4:04] <maicod> yeah when I was small my brothers and sister shared the lego
[4:04] <maicod> LOL
[4:05] <maicod> only thing I miss is the flat board like pieces
[4:05] <maicod> thin ones
[4:05] <maicod> bitplane: why not get new stones ?
[4:06] <bitplane> I guess I'll pick some up at some point, but saturday is written off already
[4:06] <maicod> OK
[4:06] <maicod> lego is for every kid :)
[4:06] <maicod> we're all kids in a sense :)
[4:07] <mrdragons> I still play with legos. >.>
[4:07] <maicod> yeah why not :)
[4:07] <bitplane> gotta stay creative :)
[4:07] <maicod> hehe indeed
[4:07] <maicod> I remember my old stones were quite dirty
[4:07] <maicod> but u can wash 'em in soapy water :)
[4:08] <bitplane> cool, dd worked that time. is it worth me expanding the partition for system files, or is 2gb plenty of space and I should add a new one for /home?
[4:08] <maicod> bitplane: I believe home uses the same system partititon
[4:08] <maicod> doesnt it?
[4:09] <DaQatz> http://www.midwestsupplies.com/plain-u-s-flag-caps-144-ct.html Should I cap some bottles with these?

[4:12] <maicod> what kinda test ?
[4:12] <Ionic`> don't wanna read everything
[4:13] <Ionic`> a friend asked me if I could test the vserver stuff he's launching soon
[4:13] <maicod> I said u're probably busy ;)
[4:13] <maicod> as in virtual server ?
[4:13] * dirty_d (~andrew@c-76-118-112-146.hsd1.ma.comcast.net) Quit (Remote host closed the connection)
[4:13] <maicod> dunno what vserver is :)
[4:13] <Ionic`> yeah
[4:13] <Ionic`> virtualized server
[4:13] <maicod> on the Pi ???
[4:14] <maicod> vmware on the Pi LOL
[4:14] <Ionic`> nah
[4:14] <Ionic`> on a real server
[4:14] <maicod> hehe thought so
[4:15] <mru> the pi seems a bit towards the small end for that
[4:15] <maicod> Pi's are litle lazy :)
[4:15] <maicod> yeah:)
[4:15] <mru> not to mention it lacks hw support for such things
[4:15] <mru> need a cortex-a15 for that
[4:15] <maicod> does it really need to have cpu hw support ? my pentium4 hasnt got it either and vmware works fine :)
[4:16] <mru> the overhead is much lower with hw support
[4:16] <maicod> oh like that
[4:16] <maicod> ofcourse
[4:16] <maicod> newer cpu's have it builtin huh
[4:16] * maicod needs a new pc :P
[4:16] <mru> they have things like nested page tables
[4:17] <maicod> oh ok
[4:17] <mru> and a bunch of instructions can be set to trap to the hypervisor
[4:17] * Ionic` needs a new maicod
[4:17] <maicod> OK hypervisor is the controller of all vms huh?
[4:18] <maicod> ionic: LOL
[4:18] <mru> yes
[4:18] <maicod> ok like the window of vmware on my pc :)
[4:18] <mru> it's a level above the supervisor (aka OS)
[4:18] <maicod> cool stuff that virtualisation
[4:18] <mru> now a hosted hypervisor complicates stuff a little
[4:19] <Ionic`> hypervisor iis your host system
[4:19] <mru> in a 'pure' setup, yes
[4:19] <maicod> ionic: I'll return you @ the empty bottles department :)
[4:19] <mru> not with things like vmware workstation
[4:20] <mru> there the hypervisor runs in cooperation with a host OS
[4:20] <Ionic`> true
[4:20] <maicod> mru: the hypervisor runs as an OS instead of IN an OS ?
[4:21] <bitplane> awesome, I'm up and running! gonna have some fun with this in the morning. Thanks again for the help!
[4:21] <maicod> goodluck bitplane
[4:21] * bitplane (021d325b@pdpc/supporter/professional/bitplane) Quit (Quit: Page closed)
[4:22] <mru> with products like vmware esx server (or whatever they call it these days), the hypervisor has full control of the hw, which it allocates to the guest VMs inside, each of which runs an OS
[4:23] <maicod> yeah bit does the hypervisor need an OS to run inside of it ?
[4:23] <maicod> like vmware runs in my windows ?
[4:23] <PhotoJim> yay, my second pi is running.
[4:23] <mru> the hypervisor is an OS of sorts
[4:23] <maicod> bit=but
[4:23] <maicod> thats what I meant mru
[4:23] <Ionic`> a pass-through OS
[4:23] <Ionic`> if you want
[4:23] <maicod> right !
[4:23] <maicod> thats better than using windows or such and run vmware inside it
[4:23] <Ionic`> uhm
[4:24] <Ionic`> what?
[4:24] <mru> depends on what you need
[4:24] <mru> it can certainly be more robust
[4:24] <mru> the hypervisor is generally quite small
[4:24] <maicod> well instead of running vmware workstation in your real OS you just run the hypervisor in its own little OS
[4:25] <maicod> sounds cool :)
[4:25] <mru> but then you need to run all your real stuff in a virtual machine
[4:25] <maicod> yeah
[4:25] <maicod> thats true
[4:25] <mru> which is a bit slower than running the OS directly on the hw
[4:25] <maicod> indeed
[4:25] <mru> and gaming is probably out of the question
[4:25] <maicod> :)
[4:26] <Hodapp> mru: VMs can run plenty fast for gaming if the guest can do OpenGL passthrough acceptbly
[4:26] <Hodapp> VirtualBox supports this on a lot of guests
[4:26] <maicod> but I mean like companies who have many virtual servers
[4:26] <mru> with a hosted hypervisor, the host OS has full control and runs at full speed
[4:26] <mru> but if the host OS crashes, all the VMs go down with it
[4:26] <maicod> they use BIG servers that run virtual servers inside
[4:27] <mru> mainframes do most of that stuff entirely in hw
[4:27] <mru> have done since the 70s
[4:27] <maicod> ok
[4:27] * maicod is off to a pause now
[4:27] <maicod> back later
[4:27] * maicod is now known as maicod_afk
[4:28] <mru> if all you need to do is run the odd app in another OS, a hosted VM is probably the best choice
[4:28] <maicod_afk> yeah like I have here now
[4:28] <maicod_afk> run ubuntu in my windows xp :P
[4:28] <maicod_afk> ionic said I should vv it :)
[4:28] <Ionic`> ?
[4:28] <Ionic`> what did I?!
[4:29] <maicod_afk> run virtual windows in real ubuntu
[4:29] <maicod_afk> instead of using windows as a base :P
[4:30] <maicod_afk> or other linux distro ofc
[4:30] <mru> that's probably a better idea
[4:31] <maicod_afk> but I grow up with windows :)
[4:31] <mru> just think of it this way: which one is more likely to crash?
[4:31] <maicod_afk> I mean I've grown up
[4:31] <maicod_afk> hehe yeah
[4:31] <Ionic`> uhm
[4:31] <Ionic`> when have I ever said that?
[4:31] <mru> Ionic`: are you calling him a liar? :)
[4:31] <maicod_afk> ionic: I remembered that you made such a remark but maybe it wasnt you but someone else
[4:31] <Ionic`> I would never, ever recommend Ubuntu
[4:31] <Ionic`> not even virtualized
[4:32] <mru> that makes two of us
[4:32] <mru> but if someone insisted on running ubuntu and windows, I'd recommend windows be the guest
[4:32] <Ionic`> hm
[4:32] <Ionic`> nope, I'd recommend the other way 'round
[4:33] <mru> why?
[4:33] <Ionic`> migrating a linux-vm is easy
[4:33] <Ionic`> try to migrate a windows-vm and die
[4:33] <maicod_afk> ionic: heheh
[4:33] <maicod_afk> ok guys i'm out for now
[4:33] <Ionic`> also, I've had bugs with different virtualization technologies and windows guests, like locking up for 2 seconds or so every x minutes, with x quite small
[4:34] <mru> guest locking up or host locking up?
[4:34] <Ionic`> guest
[4:34] <Ionic`> only the vm
[4:35] <Ionic`> it vanished when I switched from virtualbox to kvm
[4:35] <mru> hmm, I've seen such lockups too
[4:35] <Ionic`> but this switch also meant reinstalling windows and transfering all the data
[4:35] <mru> running win7 in vbox
[4:35] <Ionic`> right
[4:35] <Ionic`> that. :)
[4:35] <mru> but I only do it for a few minutes every few months

[4:36] <Ionic`> to the best of my knowledge, windows behaves better on real hardware, while linux just doesn't care
[4:36] <mru> linux is aware of the hypervisor
[4:36] <mru> and plays nice
[4:36] <Ionic`> even when it's not aware, it mostly plays nice

[4:37] <Ionic`> so if you want to save yourself some headaches, windows as host and linux as guest is the way to go
[4:37] <mru> actually, that would be far worse for me
[4:38] <Ionic`> (asuming you're using both systems daily and extensively)
[4:38] <mru> I do everything in linux
[4:38] <Ionic`> both of them
[4:38] <mru> except when I need to file an expense claim
[4:38] <mru> that's done on a stupid website that really only works with IE
[4:39] <mrdragons> mru: Surely you could spoof the user agent with firefox?
[4:39] <mru> that gets past the initial block
[4:39] <mru> but it really doesn't work
[4:39] <mru> I never bothered finding out why
[4:40] <mrdragons> I didn't think anyone actually made websites like that any more. 0_o
[4:40] <mru> enterprisey people do
[4:40] <Ionic`> mru: if you just need the windows guest every now and then, sure, linux as host and windows as guest
[4:41] <Ionic`> I was assuming that both systems are used equally extensive
[4:41] <mru> then I'd get another real computer
[4:41] <mru> or rather, use one of the ones just standing around

[6:22] <prpplague> HA
[6:22] <cjbaird> I did 'distributed computing' as a final-year subject at Uni... And I've always want a home cluster-- and now the Raspberry Pi allows such /without massive electricity bills/ :P :)
[6:22] <maicod> yeah :)
[6:23] <maicod> you might get total processing power of ............ ONE I3 or so :)
[6:23] <cjbaird> That lot should use under 20 watts.. Acceptible for 24/7
[6:23] <maicod> but the distribution sounds cool
[6:24] <maicod> I still use a pentium1 for that . it uses 40 watts or such :)
[6:24] <cjbaird> I've already done a test with distcc-- with 3 nodes, it did an entire kernel compile in 137 minutes (..down from ?7 hours)

[6:30] <Mr_Sheesh> You'd just need to strip the wires back & insert them into a plug ($5ish at a hardware shop) - Try to keep the same wire orientations to the two flat plug parts as in the original? (Mark the insulation so you know which is which, and use a continuity meter to figure out which wire is which)
[6:30] <Mr_Sheesh> It's pretty easy, diagonal cutters and a screwdriver type of job

[11:43] <JeffWBrooktree> Hi there. Is it true that raspbian should mount USB drives automatically?
[11:47] <shawnbusker> not sure, I don't believe so but I can check it
[11:48] * Weasel-Soup (~pblin@250.206.82.79.rev.sfr.net) Quit (Read error: Operation timed out)
[11:48] <shawnbusker> It does not
[11:49] <shawnbusker> Unless ntfs or fat32 is not supported
[11:49] <shawnbusker> not sure which one atm
[11:50] <JeffWBrooktree> However after mounting a flas drive manually it is possible to create directories but copying any data to it fails with an input/output error :(
[11:50] <shawnbusker> It was fat32 so if raspbian did support auto usb mounting it should have worked
[11:50] <shawnbusker> Not sure on that one
[11:51] <JeffWBrooktree> Thanks so far anyway.
[11:51] <shawnbusker> How did you mount it

[12:31] <KeyCat> Is it possible to get a I2C driver loaded without re-compiling the kernel?
[12:35] <virunga> KeyCat: the driver is a kernel module, right?
[12:38] <gordonDrogon> should be in the latest kernel.
[12:38] <gordonDrogon> so just modprobe it.
[12:39] <virunga> yeah
[12:39] <TheBrayn> can I boot the rpi from an usb stick?
[12:39] <gordonDrogon> try: sudo modprobe i2c_bcm2708
[12:39] <gordonDrogon> TheBrayn, no, but you can boot from SD, then mount root off the USB stick.
[12:39] <nid0> you need an sdcard in to load /boot but you can happily run root off the stick

[12:41] <nid0> you technically dont need to manually unmount it, as soon as its finished loading the kernel you can just pull the card out

[12:43] <KeyCat> virunga: I have not found any driver yet
[12:43] <ekselkiu> I wonder if it's worth disabling logging to avoid excessive SD card writes.
[12:43] <virunga> KeyCat: gordonDrogon suggested one to you
[12:43] <KeyCat> looking into gordons suggestion...brb
[12:44] <virunga> KeyCat: <gordonDrogon> try: sudo modprobe i2c_bcm2708
[12:45] <gordonDrogon> ekselkiu, I'd disable logging to make it a bit quicker, not to make the SD card last longer.
[12:45] <KeyCat> yes gordon was 100% correct, seems to be loaded
[12:45] <KeyCat> thanks for the help so far... I'm sure I will be back with more n00b questions ;)
[12:46] <virunga> :)
[12:46] <gordonDrogon> KeyCat, if you check: /etc/modprobe.d/ you might file a file called gpio-blacklist.conf - that stops the modules being loaded at boot time.
[12:46] <gordonDrogon> actually it might be called raspi-blacklist.conf
[12:47] <KeyCat> rgr will check.... btw: gordon thanks for the wiringPi library I managed to compile a shared lib out of it
[12:47] <gordonDrogon> so if you want them loaded at boot time, then comment out the blacklist commands.
[12:47] <gordonDrogon> KeyCat, Hm. not looked at shared libs for it as I figures only one program would be using it at a time!
[12:47] <KeyCat> and trying to get wiringPi woring from Gambas3
[12:47] <KeyCat> it seems to work
[12:48] <KeyCat> I only tested the delay function so far from Gambas3 but that works OK
[12:48] <gordonDrogon> I wrote a set of functions for my own BASIC to use wiringPi to do GPIO stuff directly from BASIC.
[12:48] <gordonDrogon> the usual issues of needing to run as root, but I've not updated my BASIC to use the /sys/class/gpio variant of wiringPi yet.
[12:49] <KeyCat> thats nice

[12:51] <KeyCat> anyway thanks again!

[13:15] * warddr (~warddr@Wikipedia/Warddr) Quit (Ping timeout: 272 seconds)
[13:16] <InControl> YRS looks interesting but does seem to focus on software that used government open data sources
[13:16] <InControl> not much hardware hacking
[13:17] <gordonDrogon> Yes, I'm only sort of finding that out now..
[13:17] <gordonDrogon> and there seems to be heavy use/support of the sponsors, etc. which i'm mildly irritated about, but I guess that's a fact of modern sponsorship life...
[13:18] <gordonDrogon> e.g. the Olympics...
[13:19] <InControl> I suppose the sponsors need to feel they are getting something out of it for the money they put up
[13:19] <gordonDrogon> I'm sure :)
[13:19] <InControl> especially in the olympics where they must pay a fortune
[13:20] <TheBrayn> anyone running gentoo on the rpi here? which useflags do you use?
[13:20] <InControl> But then I don't care about the Olympics, I'm one of the minority who isn't the sligtest bit interested in it
[13:20] <gordonDrogon> Yea, but from what I've seen/heard so-far, there seemed to be more hype before the even than is actually happening at the event - just watched the rowing with "Spar" sponsorships on their tops!
[13:20] <gordonDrogon> I'm not a fan of sport in-general.
[13:21] <shawnbusker> anyone know more about this https://github.com/raspberrypi/firmware/issues/62 ?
[13:22] <InControl> My beef with sport is that these so called stars get held up on pedestals, while scientists that are working to make a real contribution to the world get ignored.
[13:22] <gordonDrogon> I'm going to take down some Pi and Arduino kit to the YRS thing on day one to see what the young people are intersted in- you never know. But if it looks like a week of 'apps' for phones/tablets, with "cloud" services then my enthusiasm might wane.
[13:23] <InControl> gordonDrogon: that is what put me off, I was quite enthusiastic about the idea but when I looked at past projects they didn't look very interesting at all
[13:23] <gordonDrogon> shawnbusker, from what I'm reading, I think it's fair to say that sound on the Pi is somewhat better than alpha quality, but not quite beta quality yet...
[13:24] <gordonDrogon> InControl, yea... So we'll see. I'll need to take tueseday out anyway to see a client and I'm still undecided about going to Birmingham.
[13:25] <InControl> When I was at school, I did something called CREST (Creativity in Science and Technology) where we built an interface for a BBC and came up with ideas of how to use it. I had hoped that YRS might have been more along those lines.
[13:26] <gordonDrogon> I suspect it's going to take a year of the Pi and all the nice interface projects to even get the current generation of 12-17's aware that you can hook stuff up to computers and not just plug in USB keys..
[13:26] <InControl> But then I suppose things have changed and software is where it is at these days.

[13:26] <gordonDrogon> I'd left school just before the Beeb came out but had been hacking the school's Apple II ..
[13:27] <InControl> Our first school computer was a giant Research Machines 380z, big black box
[13:28] <gordonDrogon> Oh, I remember those - horrible... My last school was brand new, so got a lot of kit to play with, etc. I was only in it for 2 years before I went to uny though.
[13:28] <InControl> In the school assembly they made an announcement that they had this new computer, and asked do any of the kids have a computer at home that might be able to help them figure out how to use it !
[13:29] <gordonDrogon> So '78 and I helped them test Apple II, PET, TRS-80 and we settled on the Apple - which was then promoted through all schools in the region and was very popular until the Beeb came along.
[13:29] <gordonDrogon> :)
[13:29] <gordonDrogon> brb gotta take some bread out of the oven!
[13:30] <shawnbusker> My school still has a bunch of old Apple computers with midi in/out they used for some music class a long time ago
[13:31] <InControl> shawnbusker: some schools are real hoarders ;)
[13:31] <shawnbusker> but since then they have now upgraded to more modern computers (Dell P4's) and I think they got a grant to get iPads for every student, only time will tell though
[13:31] <InControl> Quite good though as I was able to get a BBC Domesday system becasue a school had held on to it for so long
[13:32] <gordonDrogon> another 3-4 minutes for the bread :)
[13:32] <gordonDrogon> neat.
[13:32] <InControl> Not convinced about the iPads for kids thing myself

[13:38] <InControl> There were two parts to the Domesday project, there was the community data that took pictures of your local area
[13:38] <gordonDrogon> or just stick a Pi inside a biscuit tin with some SD cards :)
[13:39] <InControl> there was the national data that collect information such as soil acidity, land use, and other physical data
[13:39] <gordonDrogon> that would have been intersting long-term study stuff - for a geographer I guess.
[13:40] <InControl> yes I think that was the primary aim
[13:40] <InControl> you had a lot of official data sets as well such as crime statistics
[13:40] <InControl> much like the government open data today ;)
[13:41] * gordonDrogon nods.
[13:41] <InControl> So you could cross reference all the data sets, so could see for example if burglary had any correlation to number of churches
[13:41] <gordonDrogon> churches being burgled...

[13:41] <InControl> just a random idea
[13:42] <gordonDrogon> So.. I guess I could play with the A/D and D/A's on the Gertboard today. I have a few hours spare...
[13:42] <gordonDrogon> wonder what the drive ability of the D/A is ..
[13:42] <dwatkins> ooh, x11vnc works on wheezy
[13:43] <InControl> so my idea was that if schools had a couple of Pi's with data aqusition that could all be fed into a central database that could be quired
[13:43] <InControl> cover several subjects then, science, geography etc
[13:43] <gordonDrogon> I did a hack weekend recently where we built a weather station - the idea was to feed the data into a Pi that would then feed it to a database...
[13:44] <gordonDrogon> the actual aquisition was via arduino and a wireless link to the Pi - although we used an old laptop in the end.
[13:44] <gordonDrogon> http://unicorn.drogon.net/aws1.jpg
[13:45] <shawnbusker> Neat
[13:45] <InControl> that is the kind of thing
[13:46] <InControl> I started building a site for it but other things have got in the way recently
[13:46] <InControl> http://community.domesdayproject.org/
[13:46] <shawnbusker> although I would have done it over ethernet or wifi, so you wouldn't have to use an arduino and a rpu

[13:50] <InControl> so would cover history as well with the 1986 data

[13:51] <gordonDrogon> sure.
[13:51] <gordonDrogon> have the original schools been contacted?
[13:52] <InControl> some of them yes, as part of the reloaded project, they seemed quite keen on it
[13:52] <InControl> trouble is the National Curriculum makes it difficult to work things in
[13:52] <brougham> there is no NC for ICT anymore
[13:53] <InControl> I think they need a clear teachers pack that shows how it can be used towards the NC
[13:53] <gordonDrogon> well - maybe this coming september will make teachers sit up and take notice once they find half their pupils own Pi's.
[13:53] <InControl> brougham: I know that is quite promising, something the BBC were pushing for as tehy have plans for a new computer litereacy project

[13:56] <gordonDrogon> I'm actually going to try to get some more work like that as I did quite enjoy it - but I think teaching adults who are keen (and paying!) to learn is much different from teaching young people.
[13:56] <InControl> yes a world apart
[13:57] <InControl> the teacher is always to blame in schools, no support from parents, frightning job if you ask me.
[13:57] <gordonDrogon> yea, I'm sure...

[14:00] <InControl> gordonDrogon: don't forget the bread
[14:00] <markbook> Part of the reason lots of teachers like to teach extra-credit or after-school clubs is because of the difference in enthusiasm and engagement even if it's not a "primary class". It seems like they're "donating" when in addition the teaching is more fun and more rewarding than normal classroom.

[14:24] <ReggieUK> but
[14:24] <jon1012> yup...for that stuff I'm used to use stm32f4 :) but I wanted to make a simple python tft lcd lib for the raspberry pi users
[14:24] <gordonDrogon> if you want even faster, then you can mmap the /dev/mem interface yourself and poke the bits directly... wiringPi goes via an abstraction layer to work out the pin and port numbers, etc.
[14:24] <ReggieUK> it's really going to end with you writing your own driver and as gordon has mentioned, the biggest obstacle will be linux itself

[14:51] <jon1012> well, I have to try using SPI
[14:51] <gordonDrogon> are you using the Python GPIO code?
[14:51] <jon1012> yeah
[14:51] <jon1012> well
[14:51] <jon1012> I tried the python gpio and the wiringpi bindings
[14:51] <jon1012> with nearly same results
[14:51] <jon1012> (all in python)
[14:52] <gordonDrogon> right. I don't know much about the Python bindings, but it might depends on which wiringPi initialiser it's using.
[14:52] <gordonDrogon> Also the fact that Python is interpreted might be an issue too.
[14:52] <jon1012> I used the initializer you told me, doesn't change much
[14:52] <jon1012> yeah
[14:53] <gordonDrogon> if you know how to interface to C, then I'd be tempted to write the routing that dumps the whole screen to the display in C, then just call it from Python, passing the Python version of the screen buffer into it...
[14:53] <jon1012> is there a simple way to use spi as bitbang with clock & data in wiringpi ?
[14:53] <TheBrayn> does the official raspbian version use dhcp to get an ip?
[14:53] <gordonDrogon> TheBrayn, yes.

[14:53] <TheBrayn> ok strange
[14:53] <gordonDrogon> jon1012, there is a serialOut function in wiringPi.

[15:24] <dirty_d> i got 4.7MB/sec downloading a file from my PC to /dev/null
[15:24] <gordonDrogon> however it really drops when I try full duplex - USB is only a half duplex bus.
[15:24] <mru> usb isn't a bus
[15:25] <gordonDrogon> dirty_d, what download method?
[15:25] <dirty_d> gordonDrogon, scp
[15:25] <Halts> <+Martin`> then you need to enable ssh :)<-- I can't enable anything if I don't have an input device :D
[15:25] <gordonDrogon> dirty_d, scp will be cpu limited due to the encryption.
[15:25] <mru> and I'd argue it's only quarter duplex

[15:26] <Martin`> damn I failed
[15:26] <mru> so it has to periodically poll devices to see if they have anything to say

[16:59] <dreamon__> I want this one to give it a try. GPIO4 is used to read a 1Wire connection. Whats the right pin to connect?
[16:59] <dreamon__> I have two different layouts for.
[17:00] <InControl> GPIO-4 = P7
[17:01] <dreamon__> I have a picture that shows mit gpio-4 on Pin 16
[17:01] <dreamon__> maybe from alpha version ?
[17:02] <InControl> that is an OLD and confusing picture
[17:02] <InControl> from before the production boards
[17:03] <dreamon__> This one -> http://benosteen.wordpress.com/2012/04/24/raspberry-pis-onboard-serial-connection/
[17:03] <InControl> that is no use to you
[17:04] <InControl> Someone made serious confusion by producing that illustration.
[17:04] <gordonDrogon> dreamon__, have a look at this diagram too: https://projects.drogon.net/raspberry-pi/wiringpi/pins/

[17:05] <gordonDrogon> dreamon__, GPIO 4 is .. well, GPIO 4, It's physical pin 7 on the connector, or the 4th down on the inside...
[17:05] <InControl> The reason that came about is that there are 8 pins that are used as a group of parallel IO's but someone named them using a GPIO prefix that was wrong.
[17:06] * cerberos (~cerberos@host81-131-182-219.range81-131.btcentralplus.com) has joined #raspberrypi
[17:06] * PiBot sets mode +v cerberos
[17:06] <gordonDrogon> the first version started numbers at zero - ie. the first usable gpio pin (pin 0), the 2nd usable gpio pin (pin 1) and so on.
[17:06] <gordonDrogon> I adopted that for wiringPi early on - which is what the arduino folks do too.
[17:07] <gordonDrogon> then all the old-hands at Linux GPIO jumped up and down and whinged..
[17:07] <InControl> So now only two numbering schemes are officially used, the internal GPIO signal name from the broadcom chip and the physical pin numbers on the board.
[17:07] <gordonDrogon> so now for the most part, they're numberd based on the name of the pin that comes out of the chip...
[17:07] <gordonDrogon> and wiringPi has a 3rd numbering scheme :)
[17:08] <InControl> All they needed to have done was change from using the GPIO prefix to stop the confusion but heyho
[17:08] <dreamon__> What a hard lesson.. that costed me hours.. searched a fault in my programm.. fu**
[17:09] <InControl> if it is any consolation you are not the only one that got confused by that
[17:10] <dreamon__> Some guys took the Pin numbers, other the gpio numbers and there were different pictures. oh gott it was not my fault ;)
[17:10] <gordonDrogon> yea, I got really confused early on too.
[17:10] <InControl> It was just a stupid mistake made by someone to use GPIO to describe both the internal signal names and the parallel IO pins.
[17:11] <dreamon__> Thank you, guys I make a plan on my own, so it will work, once and forever ;)
[17:11] <gordonDrogon> mixture of old Linux GPIO folks and newbiew coming into Linux IO and a lot from arduino land (like me)

[17:16] <gordonDrogon> only seems I can shove 10,000 samples/sec down the SPI bus to the D/A chip.
[17:16] <gordonDrogon> dreamon__, I keep meaning to make a proper "picture" of my version, but not enough tuits in the day )-:
[17:17] <InControl> 10khz is a bit low
[17:17] <InControl> or is that 10,000 bytes per sec ?
[17:17] <dreamon__> gordonDrogon, ;)
[17:17] <gordonDrogon> well it's 10,000 writes of 2 bytes.
[17:18] <gordonDrogon> and I'm doing it twice, one to each channel, to 40,000 bytes/sec.
[17:18] <InControl> with overhead that would account for the 20Mhz then I suppose
[17:18] <gordonDrogon> forgot I was doing it to both channels.
[17:19] <gordonDrogon> sending a sine wave down one, and a cosine down the other so I can check them on the scope.

[17:22] <jon1012> gordonDrogon: tis there a way to send strings to the spi ?
[17:22] <jon1012> gordonDrogon: even in c

[17:23] <gordonDrogon> jon1012, however if you fetch the latest, it's got code in it to drive the PiFace which uses SPI.

[17:23] <gordonDrogon> InControl, I'm trying my hardest to promote wiringPi ;-)
[17:24] <gordonDrogon> jon1012, today I'm writing some code to access the SPI chips on the Gertboard...
[17:25] <InControl> shouldn't gert or farnell be doing that ?
[17:25] <gordonDrogon> jon1012, http://unicorn.drogon.net/gertboard.c
[17:25] <gordonDrogon> InControl, well farnell are being rubbish right now, Gert did write some code early on, but it didn't use the kernel driver.
[17:26] <gordonDrogon> but the kernel driver is there and works - I'm just making it easy for others who want to use my code...
[17:26] <InControl> I guess what I'm saying is farnell will be benifiting from your work for free ;)
[17:26] <gordonDrogon> I think it's hard to make a genenric SPI driver (in userland) as each SPI device needs different data/commands sending it to it.
[17:27] <gordonDrogon> InControl, I think Gert will be the one benefiting financially :)
[17:27] <gordonDrogon> and I'd like to think the community will benefit in-general.
[17:27] <InControl> Sadly I'm not a software person otherwise I would help out
[17:28] <InControl> What I would like to see is a modular system, where one kernel driver can load sub modules for different protocols
[17:28] <InControl> so that the same driver can be used for all GPIO boards
[17:28] <InControl> just has a config file to load the appropriate modules for the apropriate board.

[17:29] <InControl> anyway got to shoot off
[17:29] <gordonDrogon> well the die-hards will tell you that that already existis in the /sys/class/gpio interface.
[17:29] <gordonDrogon> InControl, ok.
[17:29] <javispedro> wasn't anyone surprised that the rPI sound card seemingly has hardware mixing support? :)
[17:30] <InControl> even better if the GPIO boards had an SPI EEPROM that could tell the pi what it is
[17:30] <jon1012> gordonDrogon: I've found that : http://www.brianhensley.net/2012/07/getting-spi-working-on-raspberry-pi.html and that : http://www.brianhensley.net/2012/02/python-controlling-spi-bus-on.html
[17:30] <gordonDrogon> InControl, not all gpio cards use spi ...
[17:30] <InControl> no but if there was a standard then any board could have an SPI eeprom that the driver looked for
[17:31] <gordonDrogon> jon1012, looks fine... if you like PYthon :)

[17:31] <jon1012> gordonDrogon: I do too much C for my own sake when doing mcu dev :p
[17:31] <InControl> so at startup the driver looks for EEPROM device at a set SPI ID
[17:31] <jon1012> gordonDrogon: so when python is available, I use it
[17:32] <InControl> if the board has one it would report back all the hardware info for the board so that the driver could auto configure acordingly.
[17:33] <gordonDrogon> InControl, yea - Sun did that with their Forth OpenBoot prom ;-)
[17:33] <gordonDrogon> the trouble is, it'll make the cards cost too much, I reckon.

[18:59] <techsurvivor> you can install apt-file for that as well
[18:59] <techsurvivor> but only ones you've added I guess :)

[20:06] <ziltro2> But the fridge died before they were available.
[20:07] <ziltro2> I think I'd use an Arduino actually, and another in the freezer. Then serial connect those to a RPi.

[20:11] <techsurvivor> not sure what "infer local demand" mean? do you mean the voltage into the fridge?
[20:11] <techsurvivor> using an ammeter would probably be a better measure
[20:11] <ziltro2> Yes, the voltage in the house fluctuates
[20:11] * Milos|Netbook (~Milos@pdpc/supporter/student/milos) has joined #raspberrypi
[20:11] * PiBot sets mode +v Milos|Netbook
[20:12] <techsurvivor> voltage varies outside of the fridge, that' sjust the power grid for you, amps going in would be a much better figure of merit
[20:12] <ziltro2> As people connect loads the voltage will fall, and vice versa.
[20:12] <techsurvivor> use a killawatt or whatever it is, they have been hacked :)
[20:13] <mru> the line voltage tells you something about the electricity usage in your local area
[20:13] <mru> the current going into your appliance does not
[20:13] <Maqs> does anybody know about a fast and working solution using the pi as a thin/thick client for a virtualized system running on a linux machine?
[20:13] <techsurvivor> he wants to monitor the fride conditions though, if i understood him right
[20:13] <ziltro2> I would have though current would vary along with the voltage?
[20:14] <ziltro2> I want to monitor local voltage, to see the demand on the electricity network as a whole.
[20:14] <techsurvivor> why would you care what the voltage coming into your house is doing, other than to be a more responsible citizen ? :)
[20:14] <Maqs> kvm + vnc isn't anything near to what one would call fast :-/
[20:14] <techsurvivor> oh, i misunderstood you then :)
[20:14] <ziltro2> I was wondering if it is as simple as if the voltage goes up then not so much electricity is being used, if it goes down then more electricity is being used.
[20:14] <mru> techsurvivor: maybe he _is_ trying to be a responsible citizen
[20:14] <mru> shocking thought, I know
[20:15] <techsurvivor> could be :) . it is shocking to us typical selfish americans
[20:15] <techsurvivor> heh
[20:15] <ziltro2> Well I've heard of 'smard fridges' and stuff which appear to need links to the electricity company, and monitoring voltage would remove the need for them to have any control over your fridge. ;)
[20:15] <techsurvivor> i was thinking more about alleviating the power bill :)
[20:15] <ziltro2> Also it is an interesting project.
[20:15] <techsurvivor> it is very interesting
[20:15] <ekselkiu> ziltro2: The voltage of the power supply in your house will vary a little bit, arbitrarily.
[20:15] <mru> ziltro2: to do anything useful with "smart fridges" you do need some coordination

[20:16] * inane (~inane@unaffiliated/inane) Quit ()
[20:16] <ziltro2> I started off thinking RPi = internet connection which could, if they provided it, get demand information from the electricity company.
[20:16] <mru> if they all connect to a central control server, you can avoid them all turning on at the same time
[20:16] <mru> if everybody just monitored the local voltage, you'd probably just end up with some bad oscillations
[20:17] <ziltro2> Yeah perhaps.
[20:17] <ziltro2> Might need some randomisation or something
[20:18] <ziltro2> Also it would want to update slowly. You probably don't want to turn the compressor on or off too often.
[20:18] <mru> to maintain a given temperature differential against the surroundings, a given fridge needs to run the compressor at some specific duty cycle
[20:19] <ziltro2> Mmm, depending on temperature.
[20:19] <ziltro2> Effectively it has a temperature range, say 1??C - 4??C?
[20:19] <mru> to keep a constant temperature on the inside, the required duty cycle increases with ambient temperature
[20:20] <ziltro2> I was thinking that the simplest thing would be to limit it to, say, the top half of the range if demand is heavy, the bottom end if demand is light.
[20:20] * inane (~inane@unaffiliated/inane) has joined #raspberrypi
[20:20] * PiBot sets mode +v inane
[20:20] <mru> it would be bad if all fridges in an area had their cycles synchronised
[20:20] <ziltro2> Yes, probably would.
[20:20] <mru> but that's extremely unlikely to happen by chance
[20:21] <ziltro2> Even if there's a power cut for a few hours?
[20:21] <mru> yes, then they'll all come on at once
[20:21] <mru> but they'll randomise rather quickly after the initial cycle
[20:21] <ziltro2> Mind you that happens already.
[20:21] <mru> since they're all a bit different
[20:21] <ziltro2> Yeah, due to different temperature conditions in each home.
[20:21] <mru> the initial spike can be a problem though
[20:22] <mru> different models too
[20:22] <ziltro2> But that is already a problem, so presumably not too bad... :)
[20:22] * inane (~inane@unaffiliated/inane) Quit (Client Quit)
[20:23] <mru> after a widespread power outage, the distribution companies stage the reconnections to avoid too bad load spikes
[20:23] <mru> but even so, it can be a bit of a problem
[20:23] <ziltro2> I did once hear the electricity people turn a switch back on, I'd love to have watched it. :)
[20:23] <ziltro2> Overhead switch.
[20:24] <mru> you wouldn't see anything spectacular
[20:24] <mru> no huge arcs or anything
[20:24] <mru> those switches are designed to avoid that
[20:24] <ziltro2> It made quite a bang.
[20:24] <ziltro2> Perhaps turning it off would have been more fun, but I was in the shower at the time...
[20:24] <ziltro2> Electric shower, of course.
[20:25] <mru> the biggest risk of arcing is when you break a circuit
[20:25] <ziltro2> Yeah, that's when the fun happens.
[20:26] <mru> mostly if it's accidental
[20:26] <ziltro2> I've seen a couple of Tesla coils.
[20:26] <mru> well, that's another kind of fun entirely
[20:26] <ziltro2> Oh yes. :)
[20:27] <mru> anyway, a smart fridge can help power companies in several ways
[20:27] * M3nti0n|off is now known as M3nti0n
[20:27] <mru> one is staggered startup after a power outage
[20:27] <mru> they could also allow the temperature to rise slightly during periods of short supply
[20:28] <ziltro2> I suppose it could.
[20:28] <ziltro2> Would the staggering be in a matter of seconds?
[20:28] <ziltro2> If so a simple delay(random()) could help
[20:28] <ziltro2> ie. all fridges with CPUs could do that at startup
[20:28] <ziltro2> Wait up to 30 seconds to turn on, at random.
[20:29] * inane (~inane@unaffiliated/inane) has joined #raspberrypi
[20:29] * PiBot sets mode +v inane
[20:29] <ziltro2> Depending where random() gets its seed.
[20:29] <mru> I suspect a somewhat longer delay would be needed
[20:29] <mru> a few minutes perhaps
[20:29] <mru> maybe even more
[20:30] <techsurvivor> might be better if they could do it to AC/Heating systems :)
[20:30] <mru> suppose you have 100k fridges all wanting to start up
[20:30] <nid0> the power companies get to decide the temperature of my fridge for their convenience when they buy it for me, tbh.
[20:30] <mru> techsurvivor: yeah, that too
[20:30] <ziltro2> Yeah, heating/cooling could have a longer delay.
[20:30] <techsurvivor> that's where most of my power goes, for sure, fridge doesn't really use that much comparitively
[20:30] <mru> nid0: what if they offer you a discount on electricity?
[20:31] <ziltro2> nid0: That's what I'm trying to avoid. They can tell me if they want load or not, and my fridge can decide what to do with that information.
[20:31] <techsurvivor> might be handy to only be activated when the grid starts to get overloaded
[20:31] <mru> grid overload is become a problem in many areas
[20:31] <techsurvivor> like what happened in india, except they have about 50% of the power just being tapped into and stolen
[20:31] <mru> *becoming
[20:31] <nid0> mru: and who pays for that discount, the electricity company has to make the money somewhere, and by turning fridges down theyre supplying less power = making less money anyway
[20:32] <mru> nid0: no, they're smoothing out peaks in demand
[20:32] <nid0> "discounts" for being able to control my appliances will just come at the sake of higher default prices, bringing the discount back to the original cost
[20:32] <techsurvivor> nid0: it costs them a lot more when they blow up transformers and substations during the summer and what not
[20:32] <mru> the peak supply can be very expensive
[20:33] <techsurvivor> i was thinking more of that, here in texas we always get warnings that if we don't back off it's going to go :)
[20:33] <mru> exactly
[20:33] <techsurvivor> especially during the summer

[20:33] <mru> so if your heating/ac and whatnot received that information and reacted automatically, everybody should be happier
[20:34] <techsurvivor> i basically do my part, but it is voluntary. it's as much to keep the bills down as anything
[20:34] <ziltro2> What they could do is broadcast the information on a web site which a machine can poll
[20:34] <ziltro2> eg. a RPi.
[20:34] <techsurvivor> yeah, i'd be willing to do that when it looks like there's going to be a rolling blackout because of demand
[20:34] <techsurvivor> and rpi could monitor and send it all back ;)
[20:35] <ziltro2> I've never had anything like that... Except once when a scrapyard went on fire unterneath the two main power lines into the area.
[20:35] <mru> ziltro2: where do you live?
[20:35] <ziltro2> Yes, although sending back should be optional.
[20:35] <ziltro2> UK.
[20:35] <mru> UK is good so far
[20:35] <techsurvivor> well you could do it locally for fun, if you could hook up to your fridge temp monitoring and AC, and other things
[20:35] <ziltro2> I think I had a server on for 3 years or so, no UPS, no powercuts. But that was suspiciously near a hospital...
[20:35] <ziltro2> Also we have a DC link to France.
[20:35] <mru> since I moved to southampton 7 years ago, I haven't been without power a single second
[20:36] <techsurvivor> just have an email activatin :) "lower power 10%; 2 hours; end" lolz
[20:36] <ziltro2> I wonder where that DC link is.
[20:36] <techsurvivor> mru, it blinks here but in a year i've only had an outage for about a couple hours one night. i forget which country has the best grid, i seem to recall one of the scandanavian countries
[20:37] <ziltro2> Oh, wow, over near Dover.
[20:37] <ziltro2> I did live on a farm for a bit.
[20:37] <ziltro2> Power cuts were fairly common. I saw 250v too.
[20:37] <mru> when I lived in a suburb of stockholm, I had one power cut that I remember
[20:38] <mru> just a short time during the night, but my computer hated it
[20:38] <mru> in the countryside, brief power cuts happen a few times a year during bad weather
[20:38] <nid0> thats the joy of small overhead cabling
[20:38] <ziltro2> The 'low voltage' transformers around here all seem to have two HV cables coming in.
[20:39] <ziltro2> So any single fault can be switched out of the system.
[20:39] <mru> yeah, that minimises downtime
[20:39] <ziltro2> And everything ense should continue
[20:39] <mru> you'll probably still have a brief outage while it switches over
[20:39] <ziltro2> Oh yes, it looks manual. :)
[20:39] <ziltro2> But I suppose it might not be.
[20:39] <ziltro2> Some have levers with locks.
[20:40] <mru> oh, that manual
[20:40] <ziltro2> Pretty sure those are manual.
[20:40] <mru> but even if automatic, it would need to go out briefly
[20:40] <ziltro2> It is a little rural here, not very. There are some single phase HV supplies around.
[20:41] <mru> power grids are complicated things
[20:41] <ziltro2> Yeah, I've been mapping what I can see on OpenStreetMap. :)
[20:41] <ziltro2> The substation switches have labels naming where they are connected to, which is useful if you can read it.

[21:25] <ekselkiu> I don't want *another* useless USB hub :P
[21:25] <[SLB]> makes sense :)
[21:25] <ekselkiu> If the 4-port one can supply 3.5A to one USB port then I can chain the 7-port one I have :)
[21:25] <ReggieUK> hmmmmmmn
[21:26] <ReggieUK> that 7 port will actually be 1 4 port hub going into a 2nd 4 port hub going into the smsc chip going into the pi's usb
[21:26] <ReggieUK> sounds like fun

[21:27] <ekselkiu> Yes.
[21:28] <ekselkiu> Oh, the data going through those? What would be the problem?
[21:28] <ekselkiu> A bit slow?
[21:28] <ReggieUK> afaik it's to do with endpoints and how they're handled
[21:28] <timg> is there any way to make the rpi faster
[21:28] <ReggieUK> you will run out quicker
[21:28] <timg> I was reading on hexxeh's blog where he mentions something about taking some of the video memory and putting on system memory
[21:28] <ReggieUK> because they're taken up by the hubs
[21:29] <timg> often times it doesn't take my mouseclicks
[21:29] <ekselkiu> timg: Yes, you can control how much memory is reserved for the GPU.

[21:47] <techsurvivor> it could be, but as long as the switch is efficient you won't know

[21:47] <techsurvivor> oh yeah, 1 port for the hub
[21:47] <techsurvivor> heh
[21:47] <techsurvivor> you're right
[21:47] <Ionic`> which makes 13
[21:47] <techsurvivor> or it could be a real chip with 12 usb ports
[21:48] <Ionic`> could be
[21:48] <techsurvivor> would be cheaper if you're an asic company to do that
[21:48] <Ionic`> I know that most 7-port usb hubs are made up of 2 4-port-controllers
[21:48] <Ionic`> where the second one is connected to one port of the first
[21:48] <techsurvivor> never took one apart, it shouldn't make much difference as a user though

[22:33] <mongrelion> so I just received my Raspberry Pi and, stupid me, I ain't got a proper power supply for it. Neither I have a keyboard nor a mouse xD I've got this adapter for a Palm I used to have. It's a 5V and 1.0A one, and I know the raspberry asks for 700mA. I was wondering if 1000mA was too much for it.
[22:33] <stephan48> is there a way to get the core temperature of the raspberry pi(and maybe of the usb/lan chip) in software?
[22:33] <ekselkiu> mongrelion: Power supplies are voltage sources. You can't have too much current. The device draws what it needs.
[22:33] <stephan48> or would i have to use a external sensor?
[22:34] <ekselkiu> mongrelion: However, if the voltage is not well regulated, the pi might be unstable.
[22:34] <ekselkiu> mongrelion: So if it's 5V and actually has a micro-USB plug, give it a go.
[22:34] <bertrik> I found that with a simple 5V USB charger, the board would start but USB and ethernet didn't work

[22:35] <mongrelion> ekselkiu: -^
[22:36] <mongrelion> is there a way to measure the voltage drop for this charger?

[22:36] <mongrelion> I've got a tiny tester here... if it is usefull in this case.
[22:36] <bertrik> I think there is 5V test point on the board
[22:37] <bertrik> you could measure the voltage difference between ground and that with a multimeter/voltmeter
[22:37] <mongrelion> OMG the power supply is not a jack plug /o\

[22:40] <stain> mongrelion: but if you have not got a micro USB cable..
[22:40] <mongrelion> so the raspberry pi might try to draw more voltage <?> and then the charger might fail and explode like a nuclear bomb?
[22:40] <trevorman> stephan48: nope. no temperature sensor in the rpi at all.
[22:40] <mongrelion> I do. This is a charger for a LG Optimus One P500

[22:44] <bertrik> make sure to check out raspbmc
[22:44] <mongrelion> I have just downloaded raspbian from raspberrypi.org Is that one ok?
[22:45] <BCMM_> how fast is the SD card reader on the Pi? what is the fastest class worth getting?
[22:45] <bertrik> It's a very good start
[22:45] <mongrelion> I use archlinux on my servers, though, but read that raspbian gets the most from the hardware.
[22:45] <BCMM_> i mean, is there an actual performance difference between a class 6 and a class 10?
[22:45] <bertrik> I think I got something like 11 MB/s from a class 10 card
[22:46] <bertrik> The class X rating is the minimum sustained throughput in megabytes if I understand correctly
[22:46] <ekselkiu> * megabytes per second
[22:46] <mongrelion> how to know what's my SD card's class?
[22:46] <techsurvivor> writing throughput
[22:46] <ekselkiu> mongrelion: I don't think they tend to say on them.
[22:46] <techsurvivor> write an image to it and you'll get a pretty good guess :)
[22:47] <ekselkiu> :)

[22:47] <ekselkiu> BCMM_: Mine doesn't :(
[22:47] <BCMM_> it's a number in a little broken circle
[22:47] <ekselkiu> Ohh, mine does! :D
[22:47] <bertrik> Then it's probably not a very fast one ... :)
[22:47] <BCMM_> ekselkiu: if it doesn't say it's usually not good
[22:48] <ekselkiu> It's a class 10. I didn't notice the circle.
[22:48] <ekselkiu> It's supposed to be 32G but it's only 30GiB
[22:48] <bertrik> I think raspbian already has the readahead_kb thing set to a sensible value
[22:49] <BCMM_> ekselkiu: http://en.wikipedia.org/wiki/Secure_Digital#Speed_Class_Rating shows the symbols
[22:49] <InControl> storage devices always have less than the raw data value
[22:49] <ekselkiu> Is some used for wear-levelling information?
[22:49] <BCMM_> bertrik: so it's likely to be worth using a class 10 then?
[22:49] <InControl> first often use 1000 bytes as a KB instead of 1024
[22:50] <InControl> second space reserved for isolating bad blocks
[22:50] <bertrik> BCMM_, I think so, but haven't done any measurement to back it up though
[22:50] <ekselkiu> Hmm, 32G = 29.8Gi
[22:50] <techsurvivor> what is that disk utility everyone uses for disk performance?
[22:50] <bertrik> hdparm I guess
[22:50] <InControl> third when formatted there is the formating structure using space
[22:50] <ekselkiu> "Formatting structure using space"... I looked at the actual block device size.
[22:51] <BCMM_> bertrik: oh wait, classes are rated for write speed
[22:51] <techsurvivor> i think there is something a little more thorough, will look around, that would be a neat experiment to run, but it would have to be taken with a grain of salt without lots of differnt brands tested
[22:51] <BCMM_> because they're based on being able to record video in real-time at various bitrates
[22:51] <techsurvivor> that's what i said, try to write and image and look at the throughtput dd will tell you
[22:52] <bertrik> "sudo hdparm -tT /dev/mmcblk0" gives read speed
[22:52] <bertrik> I'd guess that a card with a high writing speed would also read quite fast
[22:52] <ekselkiu> Caching and buffering gets in the way here. I "wrote" half a gig to my SD card in seconds, yet it took quite a while to actually finish writing.
[22:52] <techsurvivor> iozone was the one I was thinking about
[22:52] <BCMM_> does anybody have any opinions on best SD cards to use with the Pi (i mean, decent read AND write speeds, and not buggy)?
[22:53] <techsurvivor> i'm using numerous cheap ones that work fine :)
[22:53] <ekselkiu> BCMM_: http://elinux.org/RPi_VerifiedPeripherals#Working_SD_Cards
[22:53] <techsurvivor> and then there is the list :)
[22:53] <BCMM_> ekselkiu: yes, but that's just a list of working cards - wondering what's fast and what's slow
[22:53] <techsurvivor> i should put the ones I have on there, and give back to the community
[22:53] <bertrik> I use a cheapie AData class 10 8 GB card
[22:54] <techsurvivor> hah i have 3 cheapie "topram" sd cards
[22:54] <techsurvivor> rated at 10
[22:54] <techsurvivor> $8 a piece I think
[22:54] <bertrik> I get 18.65 MB/s read speed from the hdparm -tT test
[22:55] * mru recommends sandisk cards
[22:57] <trevorman> BCMM_: the class rating is slightly messed up because 2,4,6 and 10 refer to different performance ratings
[22:57] <stain> I get 18.30
[22:58] <BCMM_> trevorman: how?

[22:59] <BCMM_> seeing as how the SD adaptor has a kingston logo and the uSD doesn't
[22:59] <trevorman> BCMM_: class 10 is minimum sequential write to an unfragmented card
[22:59] <ekselkiu> BCMM_: Hmm, dodgy :_\
[22:59] <BCMM_> it does not work well, errors in dmesg and 90% iowait for ages doing simple things
[22:59] <BCMM_> trevorman: huh, that's odd
[23:00] <trevorman> they made the class 10 spec for SD video cameras
[23:00] <bertrik> I would have guessed that sd card problems would have been solved in the general linux kernel for ages already
[23:01] <trevorman> bertrik: you're at the mercy of the controller itself, the controller drivers and whoever made the internals of that SD card

[23:02] * PiBot sets mode +v cave
[23:02] <trevorman> loads of fakes as well which makes it extra fun
[23:02] <bertrik> and you sometimes have to be more lenient than the sd spec
[23:02] <BCMM_> trevorman: so what are "UHS Speed Classes"?
[23:02] <trevorman> yup
[23:03] <BCMM_> does that involve bus features that the pi doesn't have?
[23:03] <bertrik> BCMM_, trevorman isn't that for SDXC cards?
[23:04] <trevorman> UHS appears on SDHC as well
[23:04] <trevorman> UHS is basically increased clock and optional DDR IIRC
[23:05] <InControl> UHS have extra terminals
[23:05] <trevorman> eh?
[23:05] * cave (~cave@80-121-51-28.adsl.highway.telekom.at) Quit (Client Quit)
[23:05] <trevorman> the problem with running stuff in UHS mode on the RPi is that it wants 1.8V which we can't do
[23:05] * blkhawk is now known as blkaway
[23:05] <InControl> the terminals are doubled up
[23:06] <trevorman> ah those. sorry
[23:06] <bertrik> so probably just plain SDHC, perhaps in high-speed mode, on the pi?
[23:06] <InControl> if you look at the pads on UHS card they are split so that they will work at standard speed in a regular SD slot but a UHS slot connects to the extra terminals
[23:06] <trevorman> the extra terminals are from UHS 2
[23:07] <InControl> ok
[23:07] <trevorman> bertrik: its best to check the list on the wiki but generally yes, SDHC from a good manufacturer
[23:07] <bertrik> trevorman, no, I mean the support on the raspberry pi
[23:07] <trevorman> I know
[23:08] <trevorman> the rpi is quirky regarding SD cards

[23:16] <trevorman> nice
[23:17] <bertrik> I'll update the wiki
[23:17] <stephan48> what would be the easiest way to connect a temp sensor(1 wire, DS18S20+) to the rpi with as less components as possible(should fit into the adafruit pi case)?
[23:19] <trevorman> I2C would be the easiest...
[23:20] <trevorman> isn't 1wire 5V?
[23:20] <ekselkiu> *with as few components as possible
[23:20] <[SLB]> what card is that bertrik?
[23:21] <InControl> Some people have used i-wire
[23:21] <InControl> 1
[23:21] <bertrik> [SLB], an ADATA 8GB class 10 card (wiki has been updated now, see http://elinux.org/RPi_Performance#SD_card )
[23:21] <trevorman> you can bitbang 1-wire on some of the gpios but you'd probably need to do level conversion since iirc it is a 5v bus
[23:22] <[SLB]> awesome thanks
[23:22] <bertrik> A DS1621 should work (i2c), I think even without any additional components (the pi has the pull-ups already, right?)

[23:28] <bertrik> mongrelion, any success yet?
[23:29] <bertrik> mongrelion, actually I'm not completely sure yet what I'll use the pi for, for now just as a general experimental board. I'm hoping to find a way so I can sample high-speed (ultrasonic) audio and use it as a bat call recorder
[23:30] <ekselkiu> bertrik: I want to do that too.
[23:30] <bertrik> power consumption seems to be a bit high for powering it off batteries though
[23:30] <trevorman> the model A whenever it is released will be less since that USB hub + ethernet chip draws quite a bit

[23:37] <BCMM_> trevorman: yeah, i know...
[23:38] <bertrik> ekselkiu, yes, 192 kHz could be enough for most species, but I'd rather have (say) 250+ kHz so you could also record lesser horseshoes
[23:38] <trevorman> the kind of correct schematic was released. I think that is it for now

[23:39] <InControl> I appreciate the work put in on the Pi, but the closed nature of it is disappointing. I was hoping to see it used as the basis for a number of projects, a sort of base hardware standard.

[23:41] <trevorman> you can tap after the tuner and feed a signal directly into the rtl chip
[23:42] <bertrik> 8 bit is sufficient, but I don't need the IQ mixer
[23:43] <bertrik> I'll look into that more
[23:43] <trevorman> ah. not sure you can disable that

[23:47] <bertrik> ah yes, I remember, only 100 mA, and those DVB-T sticks do get kind of warm (indicating high current draw)
