[0:12] <tig|> Pinhole: something sounds really wrong here, is this on one pi or multiple?
[0:13] <Pinhole> 2 pis. I think refresh every ten minutes for 3 months is over 10000 writes. I think I just gotta figure out what is writing when a pages loads.

[1:21] <Wolfram74> ok, any good trouble shooters about?
[1:21] <Wolfram74> I am in need of help
[1:22] <rikkib> Depends on what you are troubleshooting
[1:22] <Wolfram74> can't prep the bloody sd card
[1:23] <Wolfram74> I do it every 3 months or so
[1:23] <Wolfram74> and this time is proving very stubborn
[1:24] <rikkib> How much use has the sd card had?
[1:25] <Wolfram74> not much, really
[1:26] <rikkib> r/w tab?
[1:26] <Wolfram74> a few attempts at running the whole "sudo dd bs=1m if= ---" jibberish
[1:26] * troulouliou_dev (~troulouli@unaffiliated/troulouliou-dev/x-4757952) has joined #raspberrypi

[1:30] <rikkib> delete all
[1:30] <rikkib> make new Linux partition
[1:31] <Wolfram74> so, if it's address is "/dev/rdisk1"
[1:31] <rikkib> mke2fs /dev/sdx1
[1:31] <Wolfram74> or /dev/disk1s1
[1:31] <Wolfram74> i would do fdisk/dev/disk1s1
[1:31] <rikkib> e2fsck /dev/sdx1
[1:31] <rikkib> No
[1:32] <Wolfram74> fdisk: /dev/disk1s1: Resource busy
[1:34] <rikkib> fdisk mmcblk0
[1:34] <rikkib> fdisk /dev/mmcblk0 sorry
[1:34] <rikkib> Beware deleting the partition means you loose all data
[1:34] * troulouliou_dev (~troulouli@unaffiliated/troulouliou-dev/x-4757952) Quit (Quit: Leaving)
[1:35] <rikkib> Also do these things on a linux box
[1:35] <Wolfram74> is a mac close enough?
[1:35] * tombrough (~tom@cpc4-newt3-0-0-cust54.newt.cable.virginmedia.com) has joined #raspberrypi
[1:35] <rikkib> ie put sd in card reader and use a Debian box to set up cards
[1:36] <rikkib> Do not know what tools a mac has
[1:36] * tombrough (~tom@cpc4-newt3-0-0-cust54.newt.cable.virginmedia.com) has left #raspberrypi
[1:36] <Wolfram74> hrmmm
[1:37] * m8 (~m@unaffiliated/m8) has joined #raspberrypi
[1:37] <rikkib> Everything RPi is much more difficult if yoyu do not have access to a Linux boxen
[1:37] <Wolfram74> grumble grumble, i need to make a desktop tower
[1:38] <rikkib> Any old pc with 512mb ram will do
[1:38] <Wolfram74> i know, but I wanna make a tower anyway
[1:39] <rikkib> mb, ps and hard drive on a desk works to.
[1:39] * teepee (~teepee@p5084519F.dip0.t-ipconnect.de) Quit (Ping timeout: 240 seconds)
[1:40] * teepee (~teepee@p50847955.dip0.t-ipconnect.de) has joined #raspberrypi
[1:40] <pksato> run some small linux on VM.
[1:42] <pksato> but, macOS X have tools very similiar to linux.
[1:43] * m8 (~m@unaffiliated/m8) Quit (Quit: Sto andando via)
[1:43] <Wolfram74> i have my virtual machine booted up
[1:43] * darkbasic_ (~quassel@niko.linuxsystems.it) Quit (Ping timeout: 246 seconds)
[1:43] <Wolfram74> df -h has some file systems showing me
[1:43] <Wolfram74> but I can't figure out which one is the sd card
[1:44] <pksato> but, low level hw access name spaces are different.
[1:44] <rikkib> unplug it but do ls /dev first
[1:44] * wiiguy (~fake@unaffiliated/wiiguy) Quit (Quit: I just broke my connection, but no worries, we can rebuild it. We have the technology.)
[1:44] <rikkib> plug the card in again and do ls/dev
[1:44] * Syliss (~Home@dpncorp1.digitalpath.net) Quit (Ping timeout: 246 seconds)
[1:44] <rikkib> plug the card in again and do ls /dev

[1:46] * sfusco (~Adium@pool-71-178-10-126.washdc.fios.verizon.net) has joined #raspberrypi
[1:46] <rikkib> once you have it fdisk /dev/yourdevice
[1:46] <Wolfram74> it's being read by my machine, but not exactly discernably by the virtual one
[1:46] <rikkib> m for menu
[1:47] <rikkib> hmmm
[1:47] <pksato> must be have some tools to list devices on mac OS
[1:47] <rikkib> The quirks of vm's
[1:48] * debenham (~cjd@122.150.17.226) Quit (Ping timeout: 268 seconds)
[1:48] <sfusco> Hi, first time here, sorry for the intrusion. Anyone here have any experience with GPIO? I'm trying to calculate maximum brightness of an RGB LED http://raspberrypi.stackexchange.com/questions/9100/rgb-led-resistance-calculations
[1:51] <ShorTie> maximum brightness is given in the data sheet as max current
[1:51] <SpeedEvil> If you're just tryuing to work otu the resistors - you just treat it like three LEDs
[1:51] <SpeedEvil> They are electrically completely seperate
[1:52] <sfusco> So, I guess my first question is, are the pins 3.3v or 5v, or should I be running Pin 1 or Pin 2 to the common anode?
[1:52] <ShorTie> but some where in the 330 ohm is what you need for a led
[1:53] <Wolfram74> should df -h work with virtual machines?
[1:53] <sfusco> I found this, which confirmed my math: http://led.linear1.org/1led.wiz
[1:53] <SpeedEvil> 3,3V
[1:54] * Geniack (~Geniack@unaffiliated/geniack) has joined #raspberrypi
[1:54] <rikkib> RPI is not meant to drive leds... really.
[1:55] <rikkib> A buffer is always a good idea... Specially if you want max efficiency.
[1:56] <sfusco> well it will be plugged into the wall, so I'm not to concerned about batteries
[1:56] <rikkib> Other wise for testing use 1k
[1:56] <rikkib> or more to start with
[1:57] * NullMoogleCable (~NullMoogl@cpe-74-74-136-123.rochester.res.rr.com) has joined #raspberrypi
[1:57] <sfusco> so this is correct?
[1:57] <sfusco>
[1:57] <sfusco> RPi pin 7 (GPIO 4) -> RGB LED Common Anode
[1:57] <sfusco> RPi pin 11 (GPIO 17) -> RGB LED Red -> Resistor -> Ground wire
[1:57] <sfusco> RPi pin 13 (GPIO 21) -> RGB LED Green -> Resistor -> Ground wire
[1:57] <sfusco> RPi pin 15 (GPIO 22) -> RGB LED Blue -> Resistor -> Ground wire
[1:57] <sfusco> RPi pin 6 (Ground) <- Ground wire
[1:58] * Geniack_ (~Geniack@unaffiliated/geniack) Quit (Ping timeout: 264 seconds)
[1:59] <rikkib> Looks dangerous to me
[1:59] <ShorTie> got too many Ground Wires and the resistors are over 1 too far, i believe
[2:00] <sfusco> they are all the same ground wire
[2:01] * paogit (~paogit@gateway/tor-sasl/paogit) has joined #raspberrypi
[2:04] <sfusco> why is this dangerous?
[2:04] * DDave (~DDave@unaffiliated/ddave) Quit (Ping timeout: 268 seconds)
[2:04] <ShiftPlusOne> What's the total current draw you're expecting?
[2:04] <sfusco> https://www.jameco.com/Jameco/Products/ProdDS/2128500.pdf
[2:05] <pksato> Keep the extinguisher close.
[2:06] * DDave (~DDave@unaffiliated/ddave) has joined #raspberrypi
[2:07] * ManiacTwister (~Twister@rdns.s7t.de) Quit (Ping timeout: 264 seconds)
[2:07] <ShiftPlusOne> If you have chosen the right resistor values, it should be fine, I think.
[2:07] <rikkib> Turn all those leds on at max current and the smoke will come out of your rpi
[2:08] <gvo> roasted pi
[2:08] <sfusco> haha
[2:08] <ShiftPlusOne> ah, I see the problem
[2:08] * ManiacTwister (~Twister@rdns.s7t.de) has joined #raspberrypi
[2:08] <ShiftPlusOne> When the LED is on, there is no current limiting
[2:09] <rikkib> The right way to do it is drive the leds with transistors
[2:10] <ddxfish> using an external power source
[2:10] <rikkib> limit the current in the transistor base and the into the led
[2:10] <ShiftPlusOne> Well, given that it's only 3 leds, it would definitely be OK with the right resistor values repositioned correctly. Though it might be a bit dim.
[2:12] <rikkib> common anode means high side tr switch
[2:13] <sfusco> So, understanding that the correct way is with a transistor, is there a diagram of that?
[2:14] <SpeedEvil> Also note that R+G+B will _not_ give white
[2:14] * KiltedPi (KiltedPi@host-89-241-132-31.as13285.net) Quit (Ping timeout: 256 seconds)
[2:14] <SpeedEvil> With equal resistor values.
[2:14] <SpeedEvil> Or with 20mA through each LED
[2:14] <SpeedEvil> Or, indeed with the same number of lumens coming out of each LED.
[2:14] <SpeedEvil> Lighting is fun!
[2:14] <ddxfish> http://upverter.com/alexbain/f24516375cfae8b9/Open-Source-Universal-Remote/embed_img/13702922880000/ although this is for IR LED's it shows how to use a transistor and the pi
[2:14] * KiltedPi (KiltedPi@host-89-241-132-31.as13285.net) has joined #raspberrypi
[2:15] <ShiftPlusOne> Why not just hook up the annode to 3.3v and connect each cathode to GPIO through a resistor for each? Then you just drive the right pin low to turn on and high to turn off? The only problem I see is low/inconsistent brightness.
[2:17] * ManiacTwister (~Twister@rdns.s7t.de) Quit (Quit: Servus!)
[2:17] * jaimbo (97e674cb@gateway/web/freenode/ip.151.230.116.203) has joined #raspberrypi
[2:17] <jaimbo> Guys I am getting really frustrated and need help
[2:18] <jaimbo> Everytime I mount my network drive into a folder in the home directory the owner changes to root and I can't change it back
[2:19] <ShiftPlusOne> How do you mount it?
[2:19] * KiltedPi (KiltedPi@host-89-241-132-31.as13285.net) Quit (Ping timeout: 256 seconds)
[2:19] * nitdega_ (nitdega@2602:306:2423:4131:3c9d:2daa:e1c5:59c6) has joined #raspberrypi

[2:21] <rikkib> sfusco, I can't find anything on google quickly...
[2:21] <pksato> jaimbo: need to set permission (mask) or owner on mount command.
[2:21] <ShiftPlusOne> from http://linux.die.net/man/8/mount.cifs it seems that the default uid is 0 (root)
[2:22] <pksato> or have a extend attributes on server side.
[2:22] * Guest66425 (nitdega@2602:306:2423:4131:3c9d:2daa:e1c5:59c6) Quit (Ping timeout: 245 seconds)

[2:23] <jaimbo> I am not entirely sure what you mean?
[2:24] <ShiftPlusOne> to quickly test, run 'id' to find your uid and add uid=whatever to the options.
[2:24] <ShiftPlusOne> or what pksato said
[2:24] <jaimbo> Ah right ok
[2:25] * cyphernaut (~user@gateway/tor-sasl/cyphernaut) has joined #raspberrypi
[2:25] <pksato> mount point assume permissions of user that mount
[2:26] <pksato> or, if fs have unix permission style, its is applied.
[2:26] <rikkib> sfusco, http://www.coactionos.com/embedded-design/108-using-leds-in-embedded-designs.html
[2:27] <jaimbo> Hmm
[2:27] * MichaelC (~unknownbl@phpbb/website/Unknown-Bliss) has joined #raspberrypi
[2:27] <jaimbo> I tried setting the UID and GID but still not getting anywhere, forgive my noobiness please haha
[2:27] <jaimbo> I am so tired just now it hurts :(

[2:32] <rikkib> as many as you want to a point but at some point you will run into the limitations of the rpi
[2:32] <sfusco> where I can buy one of those? Jameco?
[2:32] <rikkib> any hobby shop most likely
[2:32] * ross` (~ross@spam.im) has joined #raspberrypi
[2:33] <jaimbo> I am seriously having no luck at all :/
[2:33] <sfusco> basically I just need a light to control the color of, I thought a single RGB LED would suffice
[2:33] * sphenxes (~sphenxes@91-119-95-123.dynamic.xdsl-line.inode.at) Quit (Ping timeout: 268 seconds)
[2:34] <rikkib> The rpi or any micro for that matter is meant to drive big loads
[2:34] <rikkib> is not meant sorry
[2:34] <jaimbo> "//Super-subnet/wdc_wd80_0bevs_22rst0_98 /home/pi/mynetworkdrive cifs guest,defaults,uid=1000,gid=1000 0 0" and no luck at all, still owned by root
[2:35] * Mortvert (~Mortvert@reddit/operator/mortvert) Quit (Ping timeout: 276 seconds)
[2:35] <rikkib> to the rpi 60ma is a big load for the gpio
[2:35] * dj_pi (~dj@c-107-5-25-243.hsd1.mi.comcast.net) has joined #raspberrypi
[2:36] <sfusco> and it would be 60ma because it's actually not 1 led at 20 but 3 leds each at 20?
[2:36] <rikkib> normal loads in the milli amps
[2:36] <jaimbo> I am able to interact with the drive windows side fine, but I can't read nor write on the Pi side of things
[2:36] <jaimbo> I tried setting the UID and GID but still not getting anywhere, forgive my noobiness please hahals _la
[2:36] <rikkib> yes
[2:36] <jaimbo> Whoops sorry wrong keyboard there :p
[2:37] <pksato> jaimbo: and, dont have permission to acces files or write?
[2:37] <jaimbo> Nope
[2:37] <jaimbo> ls -la shows the folder as being having owner "root" and belong to group "root"
[2:37] * ManiacTwister (~Twister@rdns.s7t.de) has joined #raspberrypi
[2:37] <sfusco> so what could it handle? without a transistor?
[2:38] <pksato> use file and dir mode settings
[2:38] <rikkib> By the way to make light of any color requires a bit a pwm
[2:38] <pksato> jaimbo: change before mount
[2:39] <sfusco> @jaimbo, you may need to set umask http://www.omaroid.com/fstab-permission-masks-explained/
[2:39] <rikkib> To make light of many color with rpi needs extra consideration due to the fact there is only one pwm

[2:46] <jaimbo> Well I am not entirely sure as it is an external drive plugged into the router
[2:46] <jaimbo> Via USB
[2:46] <pksato> use noacl option
[2:47] <rikkib> sfusco, http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf

[2:52] <sfusco> I'm basically wanting to do this same type of thing, but with a single rgb led instead of 5 in serial http://pihw.wordpress.com/lessons/rgb-led-lesson-1-creating-python-libraries-colours/
[2:52] <jaimbo> Usually now when i remount it, root gets permissions back BUT because of uid=1000 and gid=1000 both ownership and group should go to pi right?
[2:54] <ShiftPlusOne> sfusco, also, http://www.scribd.com/doc/101830961/GPIO-Pads-Control2
[2:54] <jaimbo> oh
[2:54] <jaimbo> my
[2:54] <jaimbo> god
[2:55] <jaimbo> It works, pksato, you are a god among men.
[2:55] <Wolfram74> how can i tell after "sudo dd bs=1m if=/Users/haugen/Documents/Azureus\ Downloads/raspbian-r3/raspbian-r3.img of=/dev/disk1"
[2:55] <Wolfram74> if it works?
[2:55] * jlf (~user@pdpc/supporter/active/jlf) Quit (Ping timeout: 256 seconds)
[2:56] <Wolfram74> if when i set my ras pi up, the pwr light goes on, but the act light stays a low green and doesn't do anything?
[2:56] <Wolfram74> how can i rule out the pi being broken?
[2:56] <ShiftPlusOne> Wolfram74, what's on the first partition of the disk?
[2:56] <Wolfram74> how would i investigate that?
[2:57] <ShiftPlusOne> if all the firmware files are there, it's an issue with the sd card. Unless you have booted something else from that card recently.
[2:58] <Wolfram74> I haven't successfully booted anything off this damn card, and cleaned it entirely using SDformatter
[2:58] <ShiftPlusOne> tried using NOOBS?
[2:59] <ShiftPlusOne> (just format as FAT and extract the NOOBS files on the card)
[2:59] <ShiftPlusOne> But yeah, SD card issues are common, and the dim green light indicates that the pi either cannot find the firmware or it cannot read the card.
[2:59] <Wolfram74> I tried that, can't figure out why it's not working

[3:37] <ShiftPlusOne> what language are you using?

[3:37] <sfusco> http://pihw.wordpress.com/lessons/rgb-led-lesson-1-creating-python-libraries-colours/
[3:37] <pksato> just rise pin to high level.
[3:38] <sfusco> the point is to pick a color
[3:38] <sfusco> I've got this https://github.com/reklis/raspberrypi-twitter-mood-light
[3:38] <sfusco> it's picking the color and printing it
[3:38] <sfusco> now instead of printing "orange" i want the light orange
[3:39] <sfusco> I was going to use this guy's PWM code and his same basic idea
[3:39] <ShiftPlusOne> write your own code
[3:39] <ShiftPlusOne> (it's often easier)
[3:40] <pksato> sfusco: but, you now can lit the led?
[3:40] <sfusco> this guy has a parts kit, but I don't want to drive 5 rgb leds, I just want to drive one
[3:40] <sfusco> and I don't want to spend 40$ us on his kit
[3:41] <pksato> you even dont have led?
[3:41] <sfusco> I'm trying to figure out what parts I need before ordering
[3:41] <pksato> leds resitors transistor capacitors etc...
[3:42] <ShiftPlusOne> in this case, just the leds and resistors
[3:42] <sfusco> I don't mind ordering transistors and doing an external power supply as it was suggested, because that is the "correct" way, but it seems like this other way works
[3:42] * scorphus (~scorphus@CAcert/User/scorphus) has joined #raspberrypi

[3:43] <sfusco> I don't mind doing that either, but I have a very clear purpose in mind here
[3:43] <sfusco> it's a single rgb led
[3:43] <pksato> first, lean.
[3:43] <ShiftPlusOne> it's the "correct way" if you need lots of LEDs or have something that draws a current higher than 16mA or works at a different voltage. I have no idea why they think you need a transistor to light an LED.
[3:43] <ShiftPlusOne> (unless it's a high powered one)
[3:44] <pksato> or, do like me. Destroy any eletronic of parentes/my house.
[3:44] <sfusco> ha
[3:45] <sfusco> it's really very very simple
[3:45] <pksato> but, today electronics dont have discrete parts.

[3:48] <sfusco> but it sounds like to go back to my original question
[3:48] <sfusco> RPi pin 7 (GPIO 4)   -> RGB LED Common Anode
[3:48] <sfusco> RPi pin 11 (GPIO 17) -> RGB LED Red -> Resistor -> Ground wire
[3:48] <sfusco> RPi pin 13 (GPIO 21) -> RGB LED Green -> Resistor -> Ground wire
[3:48] <sfusco> RPi pin 15 (GPIO 22) -> RGB LED Blue -> Resistor -> Ground wire
[3:48] <sfusco> RPi pin 6 (Ground)   <- Ground wire
[3:48] <sfusco> the concept is sound, I just had the wrong direction? I should be using a common cathode instead of a common anode?
[3:48] <ShiftPlusOne> sfusco, think about how much current you're drawing and sinking from each pin.
[3:49] <sfusco> ok, can I think outloud?
[3:49] <pksato> http://www.ebay.com/itm/36value-1020pcs-Waterclean-Round-Flat-Top-Straw-Hat-Rectangle-LED-Kit-998-/251322912348?pt=LH_DefaultDomain_0&hash=item3a84034e5c
[3:50] <ShiftPlusOne> 1) you're drawing all the current for all LEDs from a single gpio pin (madness). 2) you're not limiting the current correctly. The current will go into the gpio pins 17,21 and 22 rather than to ground... with no resistance there.
[3:50] <pksato> http://www.ebay.com/itm/18-value-900pcs-Bipolar-Transistor-TO-92-Box-Kit-A1015-2N5551-6-/221267491082?pt=LH_DefaultDomain_0&hash=item338491f90a
[3:50] <ShiftPlusOne> It doesn't matter if it's common anode or cathode, you'll just need to wire them up slightly differently.
[3:50] <ShiftPlusOne> Anyway, I am off. Good luck.
[3:51] <sfusco> ok, I think I see what you mean

[3:58] <sfusco> I really am trying to learn, that's why I'm here. I will get one of these books. I want to understand what this kit does though, because it very similar to what I want to do. Looking at this: http://pihw.wordpress.com/lessons/rgb-led-lesson-0-the-absolute-basics-gpio/
[3:58] <sfusco> it seems like he is doing this:
[3:58] <sfusco> RPi pin 7 (GPIO 4)   -> RGB LED Common Cathode
[3:58] <sfusco> RPi pin 11 (GPIO 17) <- Resistor <- RGB LED Red
[3:58] <sfusco> RPi pin 13 (GPIO 21) <- Resistor <- RGB LED Green
[3:58] <sfusco> RPi pin 15 (GPIO 22) <- Resistor <- RGB LED Blue
[3:58] <sfusco> ?
[3:59] <ShorTie> 11-15 ok, no need for 7
[4:00] <pksato> catode is connectd to gnd
[4:00] <ShiftPlusOne> sfusco, again, think about it. If all LEDs are on, you're drawing hell of a lot of current from GPIO 4. That circuit cannot be right.
[4:00] <ddxfish> GPIO puts out 16mA of current each i think
[4:01] <ShiftPlusOne> yes
[4:01] <ddxfish> its barely enough for 1 LED on my setup
[4:02] * debenham (~cjd@122.150.27.66) Quit (Ping timeout: 240 seconds)
[4:02] <ShiftPlusOne> depends on the LED and how much you care about the brightness.

[4:04] <sfusco> cathode to ground, that's what i thought too after reading through the adafruit and sparkfun tutorials, but that's why I can't make sense of this connections table at the top http://pihw.wordpress.com/lessons/rgb-led-lesson-0-the-absolute-basics-gpio/
[4:04] <pksato> sfusco: link you post if for multiplexed leds.
[4:05] <pksato> Its is advanced.
[4:05] <ddxfish> if you are having trouble with that, try a standard 1 color LED connected to a gpio with a 330 ohm resistor
[4:05] <ddxfish> yeah that is very complex, its not the "basics"
[4:06] <ddxfish> this is the basics: https://projects.drogon.net/wp-content/uploads/2012/06/example1.jpg
[4:06] <ddxfish> oops thats not even a controlled GPIO, its the 5v pin but still close eenough
[4:07] <sfusco> does that table make sense to anyone?
[4:07] <ShiftPlusOne> I think ddxfish was going for https://projects.drogon.net/raspberry-pi/gpio-examples/tux-crossing/gpio-examples-1-a-single-led/

[4:08] <ddxfish> or a 3v CMOS battery from a computer

[4:10] <sfusco> I get that an RGB LED is more complicated, where is the best place that can take me from single color led to rgb led?
[4:10] <ddxfish> you have to start with a single to know
[4:10] <ShiftPlusOne> sfusco, the principles are exactly the same. There is no extra step.
[4:10] <ddxfish> the learning will flow, its how i started
[4:11] <pksato> rgb led are tree leds.
[4:11] <ddxfish> yeah they are 3 combined into a single housing
[4:12] <sfusco> ok, so then let's pretend they are three different ones, that's fine, how would I wire that up?
[4:12] <ddxfish> if you know how to do 1 just do that 3 times
[4:12] <ShiftPlusOne> the same way you would wire a single one up three times
[4:12] <ddxfish> hehe
[4:13] <sfusco> ok, like so?
[4:13] <sfusco> 3.3v RPi pin 11 (GPIO 17) -> Resistor -> RGB LED Red
[4:13] <sfusco> 3.3v RPi pin 13 (GPIO 21) -> Resistor -> RGB LED Green
[4:13] <sfusco> 3.3v RPi pin 15 (GPIO 22) -> Resistor -> RGB LED Blue
[4:13] <sfusco> Rpi Ground <- RGB LED Common Cathode
[4:14] <ddxfish> you should really start with 1, is there a reason you arent?
[4:14] <ShiftPlusOne> sfusco, how did you get to that circuit?
[4:14] <ddxfish> try GPIO17 -> red 5mm LED -> 330 ohm resistor -> ground
[4:14] <ShiftPlusOne> ah actually, I misinterpreted it, nvrm
[4:15] <ShorTie> ya, that l00ks better
[4:15] <ddxfish> you can use python if you want, or install wiringPi that has some command line tools for switching on/off
[4:15] <sfusco> I've got plenty of experience with python, i'll stick with that for now
[4:15] <sfusco> the rpi.gpio stuff looks fine
[4:19] <sfusco> so, assuming that wiring is correct for common cathode, how is common anode different?
[4:19] <ShiftPlusOne> instead of ground, you connect to 3.3v
[4:19] <sfusco> all three gpios?
[4:19] <ShiftPlusOne> just the common anode
[4:20] <sfusco> ah, the other pin
[4:20] <sfusco> right, ok
[4:20] <ddxfish> common anode just means tat it shares the same power source as opposed to sharing the same ground
[4:20] <sfusco> so there are two pins the provide constant power, 3.3v and 5.0v
[4:20] <ShiftPlusOne> only use 3.3v
[4:20] <ddxfish> there are 2x 5v pins, but 3v3 is what u want
[4:20] <ShiftPlusOne> never, ever touch 5v unless you know what you're doing.
[4:23] <sfusco> ok so with the 3.3v RPi pin 1 -> common anode, R, G and B need to go to ground
[4:23] <sfusco> this is I guess the part I don't understand
[4:23] <pksato> no
[4:23] <ShiftPlusOne> no ground
[4:23] <ShiftPlusOne> to the pins
[4:23] <ddxfish> use 1 led, 1 single color lol, you wont have to ask questions then
[4:23] <ShiftPlusOne> seriously, read some background material and try a single LED
[4:24] <ddxfish> single LED is all u need, everything will make sense then
[4:24] <sfusco> I will read and come back
[4:24] <pksato> buy led and resistors anda battery, and experiment.
[4:24] <ShiftPlusOne> Let me see if I can dig up something good for you to read

[4:27] <sfusco> sorry, dropped
[4:28] <ShiftPlusOne> Current flows from positive to negative. You need current to flow into the anode and out of the cathode.
[4:28] <ddxfish> the GPIO setup you are talking about uses the GPIO pins as output, 3.3v, so the other end has to touch ground
[4:29] <ddxfish> but stick a resistor in there or it kills LED and prob the Pi
[4:29] <ShiftPlusOne> http://www.allaboutcircuits.com/vol_3/chpt_3/1.html
[4:30] <ShiftPlusOne> Read that chapter from the start up to and including 'special purpose diodes' feel free to skim through parts that seem irrelevant.
[4:30] <sfusco> ok, reading now
[4:30] <ddxfish> and if you want something that just "makes it work" https://projects.drogon.net/raspberry-pi/gpio-examples/tux-crossing/gpio-examples-1-a-single-led/
[4:31] <ShiftPlusOne> Yup, I just thought I'd give a 'difficult' source so that once he's done trying to wrap his head around the topic as a whole, the basics seem easy.... That's the theory anyway >.>
[4:32] <sfusco> I'm not really all that interested in lighting a single color led with some math that somebody else already did, I'm more interested in learning and understanding how to do it myself
[4:32] <ddxfish> you HAVE to learn with 1, its how every single one of us started
[4:32] <sfusco> ok, understood
[4:33] <ddxfish> if you want to do the math, heres something to check your resistor values with and tell what size u need http://led.linear1.org/led.wiz
[4:33] <ddxfish> and if you want to learn the math, search for Ohms law, it has many flavors

[4:36] <ShiftPlusOne> sfusco, btw, I know we are throwing a lot of information at you. I hope it's not too much and it doesn't discourage you. Once you wrap your mind around it, it really is straight forward, so take your time and think it through and you'll be fine.
[4:37] <sfusco> right, I get it
[4:37] <sfusco> I'm still reading the article
[4:37] <sfusco> besides, I'm more likely to get electrocuted than discouraged ;)
[4:37] <ddxfish> and start simple, you could even pull an LED off an old computer and try with that

[4:55] <AHemlocksLie> I have a Pi I keep at home, and I would like to be able to connect to it when I'm not at home, but I have a dynamic IP. I also rent a very small virtual private server. Is there existing software I could use to either keep tabs on the IP I need or to route through the VPS?
[4:56] <debenham> Use a dynamic dns service
[4:56] <sfusco> something like http://dyn.com/dns/
[4:56] <ddxfish> yeah dyndns.org or something
[4:56] <McBofh> AHemlocksLie: www.dyndns.org
[4:56] <ddxfish> if ur VPS runs a BIND daemon it could work if u script it
[4:56] <McBofh> just remember to set a short ttl
[4:57] <minidino> Do companies actually offer free Raspberry Pi colo?
[4:58] <ddxfish> colocation not for free lol
[4:58] <ShiftPlusOne> mingdao, yes
[4:58] <ddxfish> really? where
[4:59] <ddxfish> wow i guess they do some places so says google
[4:59] <ShiftPlusOne> I don't remember off by heart, but http://www.raspberrypi.org/archives/3685
[4:59] <ShiftPlusOne> there are others though
[4:59] <ShiftPlusOne> Hmm, AI that can learn to play NES games. https://www.youtube.com/watch?v=YGJHR9Ovszs I like how its strategy is to pause the game when losing is inevitable.... can't lose if you stop playing =D
[4:59] <minidino> http://www.edis.at/en/server/colocation/austria/raspberrypi/
[4:59] <minidino> lol it says free but there aren't any available anymore
[4:59] <minidino> idk if it was like legit though
[5:00] <AHemlocksLie> ddxfish, I'm not really familiar with scripting, but I've been looking for a reason to learn. Is a BIND daemon something I'm going to need to download, or with I maybe have it already?
[5:00] <ddxfish> yeah i see some free places that stopped doing free colo
[5:00] <ddxfish> BIND is a dns server
[5:00] <ddxfish> any VPS should be able to load it using apt/yum
[5:00] <McBofh> AHemlocksLie: http://www.isc.org/downloads/bind/
[5:00] <minidino> I wonder if the paid ones would actually end up being worth it or if its just beacuse
[5:00] <ddxfish> its not that easy though, could take a lot of scripting to make pi update the ip securely
[5:01] * redrocket (~redrocket@unaffiliated/redrocket) has joined #raspberrypi
[5:02] <McBofh> AHemlocksLie: a lot of adsl and cable modems will either let you setup an event-based update to dyndns.org (or equiv) or you can get scripts to run on your system which will do the job
[5:02] <ddxfish> a lot of routers have it too
[5:03] <McBofh> AHemlocksLie: http://dyn.com/support/clients/ is a reasonable starting point
[5:03] <McBofh> ddxfish: yep
[5:04] <ddxfish> noip.com does free dynamic dns, dyndns charges me like $10 a year, but its more reliable and popular
[5:04] <AHemlocksLie> So, what everyone seems to be saying is that my best option is to get a domain name and set up a DNS server of sorts to keep tabs on the server it should point to?
[5:04] <McBofh> pretty much
[5:04] <ddxfish> it would be hard, dyndns.org and such are much simpler for the end user
[5:05] <McBofh> dyn.com has a bundle of 2nd-level domains which you can piggyback on
[5:05] <McBofh> eg, homeunix.com (at least, they used to have that one)
[5:05] <ddxfish> and get free subdomains
[5:05] * kcj (~casey@unaffiliated/kcj) has joined #raspberrypi
[5:05] <McBofh> AHemlocksLie: go read their FAQs, they should explain pretty much everything you need on the matter
[5:05] <AHemlocksLie> If I already knew the IP of the VPS, could I perhaps instead maintain a connection between Pi and VPS to use instead?
[5:05] <AHemlocksLie> Except with one instead instead of two insteads
[5:06] <ddxfish> yes, it would pretty much require a DNS daemon (bind)
[5:06] <ddxfish> i tried on my VPS that runs my websites and messed it up lol, be careful
[5:06] <AHemlocksLie> I'm fortunately not using the server for a whole lot at the moment
[5:06] <ddxfish> your pi would do something like SSH to the vps and modify /etc/hosts or the BIND configs
[5:07] <AHemlocksLie> It's only got like 128 MB of RAM, so I mainly use it for small personal things like a little off site storage and hosting voice chat servers
[5:07] <ddxfish> 128mb must be run on openvz or something, im not sure how BIND would work on it, but it should be fine

[5:11] <ddxfish> :)
[5:13] <sfusco> ok I think I understand the "driving it low" on a common anode now
[5:13] <sfusco> because the only way the diode can open is if we make it a 0, that allows it to flow
[5:13] <sfusco> we put a resistor between the pin and the pi to protect the pi

[5:16] <sfusco> so my understanding is that if we have 3.3v going into anode constant, and the cathode run through a resistor to the gpio pin, then the pin, when high, would close the latch, when low would open the latch
[5:16] <pksato> diode permit current flow on one direction, led is a special diode.
[5:17] <pksato> But, it is not reason to understand how connect one side to +v or to 0v.
[5:18] * heathkid (~heathkid@unaffiliated/heathkid) Quit (Ping timeout: 248 seconds)
[5:18] <pksato> resistor is used to protect led.
[5:18] <ddxfish> the GPIO is used as the 3v3 source voltage, the cathode should not connect to it
[5:19] <ddxfish> GPIO 17 (outputs 3.3volts when on) -> anode -> led -> cathode -> resistor ->ground

[5:20] <sfusco> I'm trying to understand what changes when going from common cathode to common anode
[5:21] <ddxfish> it would help to start with a single LED ;) you are skipping steps and missing important info
[5:21] <pksato> sfusco: replace led for a other kind of signaling device.
[5:21] * debenham (~cjd@122.150.27.220) has joined #raspberrypi
[5:21] <ddxfish> common anode and cathode is more complicated
[5:21] <sfusco> with a single led, there isn't any common anode, you only have two pins, so you can't have this problem
[5:21] <pksato> like a bulb lamp.
[5:22] <sfusco> I understand the single led
[5:22] <ddxfish> exactly
[5:22] * phenom (~L7@unaffiliated/phenom) has joined #raspberrypi
[5:22] <sfusco> I'm trying to understand the differences between common anode and common cathode
[5:22] <pksato> anode and catode still exist.
[5:23] <ddxfish> common cathode is what you want to use IMO if you want to make it complicated, common anode if im not mistaken would be hard to control each color separate
[5:24] <sfusco> I get that common anode in this particular case makes things more complicated, but I've gotten to this place and I'm trying to learn my way out of the paper bag
[5:24] * jlf (~user@pdpc/supporter/active/jlf) Quit (Ping timeout: 264 seconds)
[5:24] <pksato> sfusco: you have a tree lamp, and tree switch, how you connect them?
[5:25] <sfusco> what is a tree lamp?
[5:25] <pksato> three
[5:26] <ddxfish> u wanna use gpios to control a tri color LED, do u know how to do 1?
[5:26] <ddxfish> its the same thing as 1, just use 3 GPIOs in output mode
[5:26] <pksato> high school problem.
[5:26] <ddxfish> share the ground (common cathode)
[5:27] <sfusco> 3.3v -> anode -> resistor (ohms = (3.3-Vf of the led) / If of the led probably .02A ) -> ground
[5:28] <ddxfish> gpio 17 -> red anode -> ground connector -> resistor -> actual ground
[5:28] <ddxfish> gpio 22 or something to the green anode, same setup
[5:29] <ddxfish> and another gpio to blue same setup
[5:29] <sfusco> sorry, I missed the led cathode in between the resistor
[5:30] <ddxfish> 3.3v @ .02A is prob too much voltage, which is why u need a resistor to drop volts
[5:30] <sfusco> and with common cathode, it looks like this…
[5:30] <sfusco> 3.3v RPi pin 11 (GPIO 17) -> Resistor -> RGB LED Red
[5:30] <sfusco> 3.3v RPi pin 13 (GPIO 21) -> Resistor -> RGB LED Green
[5:30] <sfusco> 3.3v RPi pin 15 (GPIO 22) -> Resistor -> RGB LED Blue
[5:30] <sfusco> Rpi Ground <- RGB LED Common Cathode
[5:30] <sfusco> I'm looking at these two parts:
[5:30] <sfusco> https://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2125181_-1
[5:30] <sfusco> https://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2128500_-1
[5:31] <ddxfish> Ultra Blue=3.5V the pi is not able to power this from gpio
[5:32] <sfusco> but it seems like these are too much for the pi
[5:32] <sfusco> yes, that is what I'm discovering :)
[5:32] <ddxfish> the gpio is 3.3v and 16mA (.016A)
[5:32] <sfusco> and I"ll probably end up using a common cathode
[5:32] <ddxfish> https://www.sparkfun.com/products/10820
[5:32] <ddxfish> this would work, its a tri color
[5:33] <sfusco> that's common anode
[5:33] <ddxfish> i have 3.1v 20mA LEDs and it works, crap ur right
[5:33] <sfusco> but…. supposedly that is ok
[5:33] <sfusco> I can use 3.3v from pin 1
[5:33] <sfusco> and drive it low
[5:33] <sfusco> but
[5:34] <sfusco> or… so I've been told
[5:34] <sfusco> that is the part that doesn't make sense to me
[5:34] <ddxfish> you cant turn on pin 1, its always on is the problem so u have to use the GPIO as a switch for the ground which could require a transistor
[5:34] * bsdfox_ (~Bob@unaffiliated/bsdfox) Quit (Ping timeout: 276 seconds)
[5:34] <sfusco> aha
[5:35] <ddxfish> if you had a transistor can be used to switch on an external (or for that matter, pin 1) to a specific LED by using another GPIO
[5:36] <sfusco> I'm ok with it being a lower power led

[5:38] * pksato (~PEBKAC@unaffiliated/pksato) Quit (Quit: Problem Exists Between Keyboard And Chair)
[5:38] <ddxfish> 2.0 means a 330 or 470 ohm resistor probably, the 3.2v you could use 100 for full bright, 200 for dimmer
[5:38] <ddxfish> and use a resistor for each color dont share them
[5:39] <sfusco> you say 330 but this says 68 http://led.linear1.org/1led.wiz?VS=3.3;VF=2;ID=20
[5:39] * bsdfox (~Bob@unaffiliated/bsdfox) has joined #raspberrypi
[5:40] <ddxfish> id use something higher, a 68 would be full bright, mostly for illumination rather than status indication
[5:40] <sfusco> it's going to be a twitter mood light :)
[5:40] <sfusco> kind of the point is to be bright
[5:40] <ddxfish> well then yeah use a lower value like 68, it would run ur pi hard tho i think
[5:41] <sfusco> I think 75s are cheap at jameco, looking now
[5:41] <ddxfish> i got a pack of resistors from amazon for like $10 and it has 30 types
[5:42] <sfusco> for the G and B I only need like 6ohms http://led.linear1.org/1led.wiz?VS=3.3;VF=3.2;ID=20
[5:42] <sfusco> amazon? got a link?
[5:42] <ddxfish> that will almost surely be using too much power at 20mA
[5:42] * pwh (~pwh@99-9-208-120.lightspeed.sntcca.sbcglobal.net) has joined #raspberrypi
[5:42] <sfusco> if it's prime eligible I'm in
[5:42] <ddxfish> http://www.amazon.com/600-Piece-Resistor-Kit/dp/B007L3I1ZA
[5:43] <ddxfish> prime is all i order with ;)
[5:44] <ddxfish> if you try to run a 3.3v 20mA LED with the pi it will probably dim and brighten as the CPU and power usage goes up on the board
[5:44] <sfusco> that's the other thing
[5:44] <sfusco> so if the pi itself is only getting 5V from the wall
[5:44] <ddxfish> from the PSU*
[5:45] <sfusco> … right, ok from the psu
[5:45] <sfusco> then it can't ever send 9.9v down all three of them
[5:45] <sfusco> right?
[5:45] <ddxfish> correct, BUT you could just power each anode with a GPIO and it would use no more than each anodes forward voltage
[5:46] <ddxfish> 9.9v would be if they were in serial, yours will not be in a tri color LED
[5:46] <sfusco> ah, interesting
[5:47] <sfusco> that's this part:
[5:47] <sfusco> 3.3v RPi pin 11 (GPIO 17) -> Resistor -> RGB LED Red
[5:47] <sfusco> 3.3v RPi pin 13 (GPIO 21) -> Resistor -> RGB LED Green
[5:47] <sfusco> 3.3v RPi pin 15 (GPIO 22) -> Resistor -> RGB LED Blue
[5:47] <ddxfish> yep
[5:47] <sfusco> so, there really is only 3.3v to work with ever going in total?
[5:47] * Jinx (~Jinx@unaffiliated/jinx) Quit (Quit: reboot)
[5:48] <ddxfish> in each anode yes
[5:48] <sfusco> ok, so this is key to my understanding
[5:48] <ddxfish> the milliamps would add up though, its 16mA per GPIO usually, im not sure how much for all combined
[5:48] <sfusco> it's got 5v coming in…. how can it send 3.3v * 3 out?
[5:48] <ddxfish> voltage regulator
[5:49] <ddxfish> you can always lower voltage, never raise
[5:49] <ddxfish> http://en.wikipedia.org/wiki/78xx is a voltage regulator although not for 3v3
[5:50] <ddxfish> the volts do not add up as a requirement unless they are in serial, using 3 GPIOs though is a parallel arrangement
[5:51] * debenham (~cjd@122.150.17.1) has joined #raspberrypi

[5:52] <ddxfish> if u used 3 separate GPIOs then yes
[5:52] <sfusco> right, common cathode
[5:52] <ddxfish> a tri color LED is really just 3 leds in a package

[6:03] <ddxfish> should work fine, but like I said it will still draw a lot of power from the Pi, and youll notice the CPU power usage affect the brightness
[6:04] <sfusco> analyzing the twitter stream right now bounces between 30%-50% cpu
[6:04] <ddxfish> it will dim the LEDs, i even notice dimming on my 3.1v 16mA

[6:05] <sfusco> probably so, it's got a enimax wifi in the usb port too sucking some juice
[6:05] <sfusco> I should go with bigger resistors then to get less flicker
[6:05] <sfusco> ya?
[6:05] <ddxfish> yeah i have one too, and yes it would reduce flicker a bit
[6:06] <sfusco> which is why everyone is recommending like 330 ohms
[6:06] <sfusco> to keep the power usage down
[6:06] <ddxfish> if you want a mood light that is bright though, you could consider using the 5v source power from the Pi's pin 2 and a transistor to trigger the power on and off with a GPIO
[6:07] <ddxfish> then it wouldnt flicker at all.... well not noticeably
[6:07] <sfusco> well, actually what I thought about was using a 12v wall wart and somehow diverting 5v over to the pi and the rest for the lights
[6:07] <ddxfish> ppl say to use 330 just cuz its safer for the LED and the Pi, your LED will last 100x as long if you reduce the power 10%
[6:08] <ddxfish> you could easily use a computer external molex power supply which has 12v and 5v
[6:09] <sfusco> https://www.sparkfun.com/products/11296 ?
[6:09] <ddxfish> yep
[6:09] <ddxfish> its what I use for stuff like this, they are cheap and give 2 voltages, easy to splice into also
[6:10] <sfusco> the reviews are tearing this particular one up though
[6:10] <ddxfish> ive been told this can power the Pi but i was too scared to test it direct to the 5v GPIO, it should work tho but get a second opinion on that one
[6:11] <ddxfish> they are all the same lol, but it is safer to power from the micro usb port with a 5v USB power supply

[6:15] <sfusco> any suggestions on where I could find some cheap fiber optic strands to attach to the tip of the LED so it looks like those glowing fibers?
[6:16] <ddxfish> hehe never tried that, i buy everything from amazon if they have it tho, prime is great
[6:16] <sfusco> like this http://www.lightsforalloccasions.com/p-1994-fiber-optic-led-lamp-centerpiece-clear-gems-base-multi-color.aspx?gclid=CJjGwv6Ui7kCFYOe4Aod7V8A2g
[6:16] <ddxfish> or you could use longer wires for the LED leads
[6:16] <ddxfish> thats nice, 3 AAA batteries is 4.5 volts so u could power this from the pi
[6:17] <sfusco> I just want the strands coming out
[6:17] <ddxfish> cut them and use duct tape lol
[6:17] <sfusco> i was going to just attach them to the end of the led somehow
[6:18] <ddxfish> it could be hard to align though, you might want to buy an LED with them already attached
[6:18] <ddxfish> it would require nearly perfect alignment and an angle of 0 degrees to the LED
[6:19] <sfusco> just found this http://thefiberopticstore.com/FAQ/endglow/HST-Connect.htm
[6:19] <ddxfish> this looks like some kind of mirror-coated tube that has an LED on one end and the fibers on the other

[6:37] <sfusco> that would work right?
[6:37] <ddxfish> yep but u want male to male too
[6:37] <ddxfish> they will come with a breadboard tho i bet
[6:37] <sfusco> for jumpers?
[6:37] <ddxfish> for connecting 2 points on the breadboard
[6:38] <sfusco> that's what I mean
[6:38] <ddxfish> the male to female is to hook the pi to the breadboard
[6:38] <ddxfish> or you could use a pi cobbler which is an all in 1 cable for connecting the pi to the breadboard but mine is all single wires

[6:45] <sfusco> it's better with single wires, I only need 3 going out and 1 coming back
[6:45] <sfusco> and it's easier too, because I can just put them where I want
[6:45] <ddxfish> thats why i use them too
[6:46] <ddxfish> i have a single breadboard taped to my pi case that has 5 LEDs 5 switches, motion sensor, 2 IR emitters and an IR receiver, no way to do that on one board if u use the cobbler
[6:47] <steve_rox> sounds like your havin fun
[6:47] <ddxfish> god i love my pi, ive broken 2 of them though
[6:47] * Lupinedk is now known as lupinedk
[6:47] <steve_rox> how did you manage that?
[6:48] <ddxfish> hooking up stuff wrong, shorting 5v to ground lol
[6:48] <ddxfish> and one i broke the sd card slot pulling it out of the case :(
[6:48] <steve_rox> one of mine has a broken sd reader
[6:48] <steve_rox> but its working now
[6:49] <ddxfish> i soldered an sd card adapter to it and it works but its a pain to troubleshoot if it breaks
[6:49] <steve_rox> used a bit of cardboard and glue here and there
[6:49] <ddxfish> yeah i used cardboard and superglue lol it worked for a while too
[6:49] <steve_rox> has to be done
[6:49] * debenham (~cjd@122.150.19.219) has joined #raspberrypi
[6:49] <steve_rox> but the holder is made from a nasty plastic that does not glue well
[6:49] <steve_rox> like a heat resistant plastic type
[6:50] <ddxfish> yeah the glue does have trouble gripping it, and the sd card sensor broke too so i stuck a metal sliver in the reader to make it always think its in
[6:51] <steve_rox> only thing is if it becomes loose the rpi will shift to read only and the sd is corrupt
[6:52] <ddxfish> i also set out one day to corrupt my sd card as many times as possible trying to figure out the source of the error, class 10 UHS cards
[6:52] <steve_rox> sounds mad :-)
[6:53] <ddxfish> my pi was angry with me after that, so i use class 6 now mostly

[6:55] <steve_rox> yea
[6:55] <ddxfish> wow i havent tried the camera for it thats nice resolution
[6:55] <steve_rox> alough i put a extra lense over it to help it macro
[6:56] <ddxfish> i take pics of my pi like most ppl take pics of their kids

[6:57] <ddxfish> http://www.etcwiki.org/mypi.jpg -- my broken sd slot with metal jammed in the sensor lol
[6:57] <steve_rox> internal lcd display too but hard to see from pic
[6:58] <ddxfish> nice im surprised u fit all that in there
[6:58] <steve_rox> yeah it was hell
[6:58] <steve_rox> there was no blueprint or anything , i was making it up as i went along
[6:58] <ddxfish> i just got a huge project box im mounting LEDs and switches on but im not sure if ill end up using it, not enough ventiliation
[6:59] <ddxfish> yeah i dont schematic anything before i drill holes lol
[6:59] <sfusco> what's all the yellow goo?
[6:59] <steve_rox> hot glue
[6:59] <steve_rox> i dident have any better colors
[6:59] <ddxfish> nice yeah i use hot glue a lot in electronics
[6:59] <steve_rox> and hot glue is kinda non perminant just messy
[7:00] <ddxfish> how is that powered? are u using the GPIO pins?
[7:00] <steve_rox> also have a fan if you can see it
[7:00] <sfusco> that white cable is the camera?
[7:00] <steve_rox> yeah it is
[7:00] <steve_rox> and power is routed thu the original usb power in line
[7:00] <steve_rox> direct wire soldered on
[7:00] <ddxfish> ahh
[7:01] <steve_rox> fitting the cam was hell too
[7:01] <steve_rox> the space was so tight

[7:02] <ddxfish> ohhhh thats a power supply
[7:02] <steve_rox> that is a dc-dc convt
[7:02] <steve_rox> yea :-)
[7:02] <ddxfish> nice lol thats awesome
[7:02] <steve_rox> the cap makes the power stable while switching on and off the lcd
[7:02] <steve_rox> car reverseing lcd addapted to 5v
[7:02] <steve_rox> composite

[7:04] <ddxfish> yeah i use a headless pi, its a server basically that backs up my websites

[7:07] <steve_rox> i havent even drilled the hole for the hdml socket
[7:07] <steve_rox> i figure theres no point
[7:07] <ddxfish> yeah i noticed :) i was thinking about a tiny screen for my pi too, composite obviously
[7:07] <steve_rox> it would only prevent airflow going thu the whole thing too
[7:07] <steve_rox> the fan at bottom left sucks air thu the top right audio hole
[7:07] <ddxfish> http://www.etcwiki.org/pbox.jpg this is my external LED/switch box i made, i dont use it tho
[7:07] <steve_rox> not how i planned it , just happened that way
[7:08] <ddxfish> yeah i was thinking about fans in my big box, need 2 holes tho
[7:08] <steve_rox> i mean yeah the board can take the heat , but what about other parts
[7:08] <ddxfish> i got drunk one night and woke up with that project box
[7:08] <steve_rox> wow :-P
[7:08] <steve_rox> some kinda led sequenceing by gpio?
[7:09] <ddxfish> the parts can take the heat, i wonder if the board could tho
[7:09] <ddxfish> gpio control of the pi using direct cables, those are the cathodes sticking out exposed
[7:09] <steve_rox> i should put some silly heatsinks on it too at some point
[7:09] <ddxfish> oh yeah i got those it does help too
[7:09] <steve_rox> cathodes? LED?
[7:09] <ddxfish> my pi reads 49 degrees constantly instead of 60
[7:10] <ddxfish> yeah i mean LEDs
[7:10] <steve_rox> i actually learnt how to do the whole led on off by cmd gpio the other day :-D
[7:10] <steve_rox> first time i messed with gpio
[7:10] <steve_rox> not sure where to go from here
[7:10] <ddxfish> yeah i use python for it, i love the gpio
[7:10] <ddxfish> attach switches next, then attach IR transciever
[7:10] <steve_rox> i thought maybe id like to do a relay
[7:10] <ddxfish> then a PIR motion sensor :) then a temp sensor, it was my progression
[7:11] <steve_rox> or some kinda sencor to it
[7:11] <steve_rox> what about them gass sencors?
[7:11] <ddxfish> yeah the PIR motion sensor was very easy
[7:11] <ddxfish> ive seen those and i know they can interface with a port on the pi, maybe the i2c port
[7:11] <steve_rox> would be nice to play with but i just have very limited experience in this arrea
[7:12] <steve_rox> wonder what kinda gasses it detects
[7:12] <ddxfish> it has to be set to detect each separately
[7:12] <ddxfish> carbon monoxide is most common tho

[7:13] <ddxfish> i was thinking about making a pi network that monitors a vineyard for growing grapes, humidity, temperature, i think of uses for the pi that i never get to trying
[7:14] <steve_rox> wouldent the rpi be vunrable to humidity?
[7:14] <ddxfish> quad copter was the coolest i saw so far, and yes lol it would for sure
[7:14] <steve_rox> unless you seal it in silica gell
[7:14] <ddxfish> yeah or just use a ton of hot glue lol
[7:14] <ddxfish> they have plastic at radio shack that is moldable too

[7:15] <steve_rox> macro
[7:16] <ddxfish> time lapsed photos would be perfect on the pi

[7:18] <ddxfish> use a huge resistor though hehe

[8:43] <Psil0Cybin> im having troubles using the imagewrite gui, it says it cannot find the sd card
[8:43] <Psil0Cybin> but i can see it mounted on my system
[8:44] <Psil0Cybin> and after gparting the sd card to make it fat32, it cannot be found on the windows machine
[8:44] <Psil0Cybin> so i cannot use the basic applkcation it says to us
[8:44] <sney> just use dd
[8:44] <Psil0Cybin> thats what i want to use
[8:44] <Psil0Cybin> but im confused
[8:44] <Psil0Cybin> my sd card is located on /media/sdcardname
[8:44] <Psil0Cybin> but its saying to use "of=/dev/sdc
[8:45] <Psil0Cybin> on some guide
[8:45] <Psil0Cybin> im kinda new to linux so i need help finding the sd card folder.
[8:45] <sney> right. because it needs the device node, not the mount point
[8:45] <Psil0Cybin> okay so what is the command to find out the exact device node so i dont make a mistake
[8:45] <sney> the /dev "file" is a special file that actually represents the disk itself. the /media folder is like a drive letter
[8:45] * Pitel_IPEX (~pitel@gatekeeper.bm.ipex.cz) has joined #raspberrypi
[8:46] <sney> 'sudo fdisk -l' will list the disks on your system and their names and sizes. find the one that is the same size as your SD card. it's probably /dev/sdc if you don't have any other removable drives attached.
[8:46] <Psil0Cybin> ohhh
[8:46] <Psil0Cybin> okay perfect

[8:48] <vlt> Psil0Cybin: sdb1 is one partition on sdb
[8:48] <sney> ok. remember that numbers are partitions. you want the whole disk.
[8:49] <vlt> Psil0Cybin: You want the whole device.
[8:49] <sney> so if your sd card is /dev/sdb, you want dd if=raspbian-whatever.iso of=/dev/sdb
[8:49] <sney> after dd finishes (it won't give any progress or messages, it'll just wait for a minute then give you another prompt) run 'sync' at the same prompt
[8:50] <Psil0Cybin> can i pastebin my whole fdisk output
[8:50] <Psil0Cybin> so im making sure i run the command right?

[8:54] * KiltedPi (KiltedPi@host-89-241-132-31.as13285.net) has joined #raspberrypi
[8:54] <Psil0Cybin> so i would do "sudo dd if=/home/psilocybin/Downloads/2013-07-26-wheezy-raspbian.img of=/dev/sdb"
[8:54] <sney> yes, and then afterwards run 'sync'
[8:54] <Psil0Cybin> okay
[8:54] <Psil0Cybin> phew
[8:54] <Psil0Cybin> you guys are actual geniouses :)
[8:55] <Psil0Cybin> imma do this now while u guys are on
[8:55] <sney> the linux fundamental stuff is pretty simple but nobody teaches it anymore. it comes off as voodoo but it's really not
[8:55] <Psil0Cybin> it says
[8:55] <x29a> dont spoil it
[8:55] <Psil0Cybin> dd: opening `/dev/sdb': no medium found
[8:55] <Benguin> Guhhhhh. Mumble's certificates and stuff is such bs
[8:55] <vlt> sney: ok ;-) If he unmounted it by clicking the icon ... will he still be able to write to sdb?
[8:55] <Benguin> Always causes me woe >:C
[8:55] <Psil0Cybin> vlt: i unmounted by icon
[8:55] <Psil0Cybin> and i dont think i can
[8:55] <Psil0Cybin> i got this
[8:55] <Psil0Cybin> dd: opening `/dev/sdb': no medium found
[8:56] <sney> oh, right, gnome being annoying and too clever
[8:56] <Psil0Cybin> its Xfce :P
[8:56] <Psil0Cybin> Xubuntu
[8:56] <sney> I think it's the second time this week
[8:56] <sney> whatever
[8:56] <sney> anyway
[8:56] <vlt> That's what I thought, yes ...
[8:56] <sney> unplug your sd card, plug it back in, let xfce do its thing then run 'sudo umount /dev/sdb1' before trying your dd command again

[8:57] <Psil0Cybin> thanks!! u guys are the beest, still here just running it now
[8:57] <Psil0Cybin> okay its doing something
[8:57] <Psil0Cybin> no prompt, but its in a process :)
[8:57] <sney> "oh you wanted to unmount that disk? well I'm going to trigger udev to remove the node, too. even though there's no reason you could ever want or need that. you're welcome!"
[8:57] <Psil0Cybin> i can feeellll it in my vaines.
[8:58] <Psil0Cybin> just the idea of getting this pi working is turning me on :D:D
[8:58] <Psil0Cybin> so after its done i just type in sync?
[8:58] <sney> yes
[8:58] <Psil0Cybin> sney: id kiss you if i could!
[8:58] <Psil0Cybin> same with vlt
[8:58] <Psil0Cybin> you guys deserve a gift basket or something1
[8:59] <sney> and it'll probably think for a little longer, and then once it gives you another prompt you can take your sd card out and try booting your pi
[8:59] <Psil0Cybin> YAYAYYAYAYA
[8:59] <Psil0Cybin> wooo!!! finally all my waititng is paying off

[15:23] <gugahoi> what is the point of rpi?
[15:23] <gugahoi> -update
[15:23] <RaTTuS|BIG> well some people find it hard
[15:23] <FrostyX> hi. When I want to backup my raspberry pi system, Do I have to use dd or just copy all files from card and on restore just delete card and copy files back?
[15:23] <[Saint]> gugahoi: for most users, absolutely nothing.
[15:24] <gugahoi> and for "not most users"?
[15:24] <[Saint]> Its only useful if you want absolute bleeding edge kernel and are incapable for some reason of copying a few files from a repository.
[15:25] <[Saint]> s/kernel/kernel+firmware/
[15:25] <SirLagz> I'm having a play around with aria2, it's pretty awesome
[15:25] <[Saint]> Lots of users *think* they need the latest kernel, but its very sdeldom true.
[15:25] <SirLagz> using a neat little webgui
[15:25] <hifi> install the raspbian packages on raspbian and be done with it, do normal apt-get upgrade
[15:25] <[Saint]> *seldom
[15:25] <hifi> if it breaks, blame plugwash
[15:25] <[Saint]> hifi: agreeable
[15:25] <SirLagz> lol
[15:26] <gugahoi> fair enough, shouldve known better
[15:26] <hifi> gugahoi: not really, everyone touts about rpi-update
[15:26] <[Saint]> For a while I was chasing bleeding edge for F2FS enhancements, but, it "just works" at an acceptable level now.
[15:26] <hifi> when it's the worst possible way to run a stable system, it just wastes a lot of space when it clones the git repo
[15:27] <hifi> faster and more reliable (hopefully) is to just use the packages
[15:27] <ShorTie> i hait updating linux, half the time it seems to bork my system, better off just starting new in away
[15:27] <gugahoi> i started getting some errors with the camera module and thought that was the only thing i hadnt done so wouldnt hurt to try
[15:27] <gugahoi> guess i was wrong
[15:27] <[Saint]> apt-get dist-upgrade would've done the same thing.
[15:27] <[Saint]> safer, too.

[15:29] <[Saint]> TL;DR: there's very little reason to update the kernel/firmware from any source other than apt-get/aptitude
[15:31] <[Saint]> apt-get up{date|grade} occasionally and apt-get dist-upgrade every so often should keep you in check.

[15:31] <gugahoi> good to know!
[15:32] <[Saint]> I let cron do this for me.
[15:32] <[Saint]> update/upgrade daily, dist-upgrade weekly.
[15:32] <gugahoi> thats pretty clever, what do u use ur pi for tho?
[15:32] <ozzzy> my pi functions perfectly as it is... I don't update/upgrade as it'll break
[15:33] <[Saint]> ozzzy: if simply updating breaks things, your setup is sick.
[15:33] <SirLagz> very sick...
[15:33] <ShorTie> yup, you gotta do it daily for all to go well
[15:34] <SirLagz> My pi goes for weeks on end without updating
[15:34] <ShorTie> let it go a month or 2, and blaa...
[15:34] <ozzzy> it's not sick at all...
[15:34] <SirLagz> then you're running some odd software if it breaks every update.
[15:34] <[Saint]> gugahoi: a few things. One manages shutting down/powering up/restarting my server(s) remotely. Another is a hideous touchscreen tablet kludge thing, one I use to mess around trying to get a stable Arch image at 1.8~2GHz, another is a media center.
[15:35] <[Saint]> ozzzy: breaks at upgrade == "sick"
[15:35] <[Saint]> regardless how it runs beforehand.

[15:36] <[Saint]> Quite half-heartedly, yes.
[15:37] <SirLagz> lol
[15:37] <gugahoi> wow, hows it going with that?
[15:37] <[Saint]> Not terribly well. Sometimes I can hold it stable for hours, and actually do something useful with it. Sometimes it'll trash itself immediately after boot. :)
[15:38] <gugahoi> hahaha hows the temperature? u using heatsinks or fans or something?
[15:38] <[Saint]> Something I'm playing with at the moment is a tiny Arch image that boots from the sdcard and dumps what it needs to RAM and runs entirely from RAM from then on.
[15:39] <[Saint]> There's a reasonably large passively cooled sync on it, yes. But it isn't necessary.
[15:39] <[Saint]> If I go much higher than that I need to watch out for the thermal limit though.
[15:40] <SirLagz> oooo raspbian got some new ralink firmware
[15:40] <SirLagz> wonder if that will help me at all..
[15:40] <gugahoi> that will be quite amazing if u can get that to run stable
[15:41] <[Saint]> Guys with active cooling have gone far beyond that.
[15:41] <[Saint]> The current highest I've seen held stable is around 2.5GHz
[15:41] <SirLagz> Dom reckons that the max is 1.25ghz...i wonder how you're getting 2.5ghz
[15:41] <gugahoi> damn, is there a video with that? i wonder how much better the performance is

[15:43] <[Saint]> SirLagz: the clocks seem to vary wildly between devices.
[15:44] <[Saint]> I have one unit that absolutely will not boot at anything past 1.2GHz
[15:45] <IT_Sean> 1.2GHz is pretty darn good, for a raspi.
[15:45] <SirLagz> interesting
[15:45] <IT_Sean> That's probably near the upper end of the over clocking spectrum
[15:45] <IT_Sean> Is it stable at that speed, at room temp?
[15:45] <[Saint]> ...ish
[15:45] <IT_Sean> lol.
[15:46] <[Saint]> SOme guy on OCAU got up to 4.15GHz with LN2
[15:46] <[Saint]> (it falls over within a few seconds after boot, though)
[15:46] <[Saint]> {so I guess that doesn't really count}
[15:46] <SirLagz> lol
[15:48] <IT_Sean> Yeah, that doesn't count.
[15:48] <IT_Sean> That's like claiming that a 12vDC router runs on 240vAC. ... but only for half a second.

[16:29] <gugahoi> ah i see, great to know, thanks
[16:29] <sraue> but there are so much RPi improvenments in 3.1 compared to 3.0 so its better to run 3.1/3.2
[16:29] <gugahoi> any available images out there for them? or do i need to build from source?
[16:29] <gugahoi> or myabe possible to manually update to them?
[16:30] <sraue> you can manually update from stable to testing via our provided tarfiles
[16:30] <sraue> you can downgrade the same way if you dont like 3.1.x... but i think you will like it

[17:55] <grey> heyo, can the raspberry pi+camera board transmit video and still have CPU left over? I want to do some realtime video processing on it for some drone stuff, or maybe video confrencing, but I wasn't sure how fast the GPU was with video processing
[17:55] * herdingcat (~huli@222.128.173.133) has joined #raspberrypi
[17:56] <grey> I saw the one opencv demo (which I know is very intensive) and it was using it at an extremely low resolution and framerate
[17:56] <ShiftPlusOne> that would have been a usb webcam I am guessing
[17:56] <tig|> I didn't check the cpu load when I was streaming at the weekend
[17:56] <grey> yeah? the Camera board lists that it supporst 1080p30, is that going to be consuming 99% of the CPU? Or is it handled by the onboard hardware and will let me do something with that video still?
[17:57] <linuxstb> Well, you can setup an openmax pipeline so you transmit at one resolution, and then read the uncompressed data from the GPU for processing at a different resolution.
[17:57] <ShiftPlusOne> (which wouldn't be using the GPU). The official camera uses the GPU.
[17:57] <grey> oh cool
[18:00] <RaTTuS|BIG> I was using gstreamer to transmit video from 1 RPi to 2 others with < 10% cpu usage ....
[18:00] <grey> RaTTuS|BIG: At what resolution?
[18:00] <RaTTuS|BIG> not sure now - 720x560 or it may of been 1080 .... cannot test now
[18:00] <grey> ok, thanks :)

[18:02] <grey> Yep, If you're transmitting it though, you might have to encode it to some format or something,
[18:03] <grey> I can't seem to find details on what the GPU supports in that regard
[18:03] <SpeedEvil> The issue is what does the camera driver supplied support - not really what the GPU supports

[20:49] <Dooley> I am trying to find out if I have enough GPIO pins for a second project on my RPi.
[20:49] <biamigueis> hey everyone, im new here and i was wondering what the difference is between this channel and #raspberrypi-dev
[20:49] <Dooley> I would like to use a button, and a 2x16 LCD using the GPIO
[20:49] <IT_Sean> biamigueis: -dev is for devs.
[20:50] <Dooley> I still have the following GPIO available: 4, 14, 15, 8, 7, 27
[20:50] <GriffenJBS> Dooley: what interface is the LCD?
[20:50] <IT_Sean> This channel, #raspberrypi is the one "Foundation Blessed" channel, and is more a general conversation type channel for Raspi stuff.
[20:50] <Dooley> I don't have it yet
[20:50] <Dooley> I will buy one only if I don't have to unmount my previous project
[20:50] <biamigueis> IT_Sean: what qualifies you as a dev though? I would think that anyone playing with a raspberrypi is a dev (or in the process of becoming one) in some way or another
[20:51] <IT_Sean> biamigueis: -dev is for heaver development type conversation.
[20:51] <biamigueis> ahh kk
[20:51] <biamigueis> thanks
[20:51] <Dooley> I am already using both the SDA and SCL GPIOs
[20:51] <Dooley> that may make things more complicated
[20:52] * Jayneil (~jayneil@cpe-173-175-241-63.tx.res.rr.com) has left #raspberrypi

[20:52] <Dooley> no, I know nothing about LCDs
[20:52] <IT_Sean> Dooley: The Adafruit RGB LCD kit gives you 2x16 characters, and 5 buttons, and communicates on the SPI bus.

[20:52] * [ilin] (~ilin@unaffiliated/ilin) has joined #raspberrypi
[20:53] <Dooley> which pins are the SPI bus?
[20:53] <GriffenJBS> if your LCD or other peripherals use a select signal, you can chain several of them on the same SDA/SCL pins
[20:53] * [ilin] (~ilin@unaffiliated/ilin) has left #raspberrypi
[20:53] <Dooley> I am sorry for the very stupid questions
[20:53] <IT_Sean> It's on the GPIO header, but the kit uses only 3 pins, and you can have multiple SPI devices.
[20:53] <IT_Sean> So, the rest of your GPIO pins are untouched.
[20:54] <biamigueis> so if i wanted to ask about taking apart an android tablet and using the screen+touch with the RP should i ask it here or in the dev channel?
[20:54] <IT_Sean> either is fine.
[20:54] <GriffenJBS> IIRC SPI is pins, 19,21,23?
[20:54] <IT_Sean> I do not remember the pin numbers.

[20:55] <GriffenJBS> Just did, yes I was correct
[20:56] <biamigueis> ok so has anyone tried taking apart a cheap 7" android tablet and using that with the rp? I took the tablet apart last night but i havent plugged it in because im afraid i might fry the board since im new to this :D
[20:56] <KiltedPi> RED, SO ------> MISO(PIN 21)
[20:56] <KiltedPi> BLACK, CS ----> CE0 (PIN 24) (Note: possibly CE1)
[20:56] <KiltedPi> YELLOW, SCK --> SCLK (PIN 23)
[20:56] <KiltedPi> WHITE, GND ---> GND (PIN 6)
[20:56] <KiltedPi> GREEN, VCC ---> 3.3v (PIN 1)
[20:56] <IT_Sean> biamigueis: I am guessing the display uses some flavour of LVDS, whic means it is not going to interface directly to the raspi.
[20:56] <KiltedPi> There ya go!
[20:56] <GriffenJBS> biamigueis: why not plug in a cheap usb wifi and push something to the screen for display?
[20:56] <KiltedPi> Ignore the colour bit
[20:56] <foo303> Hi all. I got an externally powered usb hub to power the DWA-131 nano wireless adaptor. That didn't quite work as expected, but after some searching around I can tell that I'm not the only one with this issue http://archlinuxarm.org/forum/viewtopic.php?f=31&t=4790 however, from the last few posts it seems that the driver for this adaptor is already included
[20:56] <KiltedPi> that was just the wiring colours I used, yours can be anything
[20:57] <foo303> alas, wifi-menu only works once with good results, but it was never able to connect to a network
[20:57] <KiltedPi> Also, sorry if that was a bit unreadable
[20:57] <KiltedPi> in IRC
[20:57] <KiltedPi> Should of PM'd in retrospect
[20:57] <foo303> I also tried rebooting and doing netctl start <the-network> and it just times out on WPA authentication, even though it's an open network
[20:58] <Dooley> it's very readable
[20:58] <foo303> by "good results" I mean: able to list the networks
[20:58] <nmpro> its soooo pretty.. :-)
[20:58] <foo303> but it never works again until I restart
[20:58] <KiltedPi> haha
[20:58] <biamigueis> GriffenJBS: because i hate that tablet and im parting it out. want to make a custom enclosure using a 3d printer for the rp + display
[20:58] <Dooley> unfortunately I am already using 21 and 23 for the other project
[20:59] <KiltedPi> People have chopped photo display frames
[20:59] <KiltedPi> heh
[20:59] <KiltedPi> I got one, but haven't got around to hacking it
[20:59] <nmpro> speaking of 3d printers.. anyone recommend a decent inexpensive 3D printer?
[20:59] <foo303> has anyone got better luck with DWA-131?
[20:59] <KiltedPi> Apparently the frame rates pretty bad on them
[20:59] <KiltedPi> inexpensive, no such thing i think
[20:59] <KiltedPi> for a 3D printer
[20:59] <KiltedPi> They're pretty dear
[20:59] <nmpro> well.. < $900.00
[20:59] <nmpro> :)
[21:00] <nmpro> is what I meant by inexpensive..

[21:33] <zero_coder> how are u guys?
[21:33] <syntax_erorr> not bad
[21:33] <[Saint]> ValDuare: that seems terribly single-use.
[21:33] <zero_coder> wondering what u do with your pi
[21:33] <Vostok> i've run into a really weird problem with raspberry pi
[21:33] <syntax_erorr> I'm working making mine into a stand alone dash cam
[21:33] <[Saint]> Why not just get a 2-way extension with USB?
[21:33] <Vostok> https://github.com/jdthomas/bayer2rgb this doesn't work on raspi, but does on almost any other machine
[21:34] <plugwash> ValDuare, sounds reasonable, just make sure you do a good strong and tidy job and appropriately secure any cables entering and leaving the box
[21:34] <plugwash> oh and don't use it with the lid off
[21:34] <Vostok> would anyone care to compile that, get this http://www.ursa.fi/~lkangas/tpub/allsky_2013-08-20_190147Z.bin and run the following command
[21:34] <Vostok> bayer2rgb -i allsky_2013-08-20_190147Z.bin -o testi.tif -w 640 -v 480 -b 16 -f BGGR -m AHD -t -s
[21:34] <Vostok> mine just says "bad arg" on raspi for no apparent reason
[21:35] <ValDuare> [Saint]: not really single use - the SOME tv's with usb ports do not produce quite enough amperage
[21:35] <ValDuare> this would allow any tv to power usb devices
[21:35] <Vostok> (really easy to compile, just run make)
[21:35] <zero_coder> has anyone been doing robots with pi?

[22:15] * doc-saintly (~root@unaffiliated/doc-saintly) has left #raspberrypi
[22:15] <mgottschlag> you'd need an LVDS/HDMI converter if your LCD has LVDS, or you need any other converter to HDMI if it doesn't :)

[22:18] <Qjimbo> SrRaven: I'
[22:18] <Qjimbo> I've seen some cheap screens on dealextreme
[22:18] <Qjimbo> that have composite input
[22:18] <Qjimbo> around $30 iirc
[22:19] <IT_Sean> You can also get a small HDMI display, car headrest sized, for not too much more, if quality of the image displayed is a concern.
[22:19] <SrRaven> Not really
[22:20] <SrRaven> I seriously only need/want it for the live preview of the pi-cam
[22:20] <SrRaven> as I want to do some DIY stuff and film the progress
[22:20] <SrRaven> although im not quite sure where to position the camera yet either :/

[22:23] <Qjimbo> only downside with DX is stuff takes a couple of weeks to arrive, so if you want it sooner you could check amazon and ebay for similar products
[22:24] <SrRaven> i know,I love ordering from china (aliexpress etc)
[22:24] <SrRaven> so much cheaper and most times,you even forget you orderd it and get a suprise :p
[22:25] <Qjimbo> haha, true that
[22:25] <steve_rox> what if customs get it
[22:25] <SrRaven> dont mind,customs office is next to my workplace :P
[22:26] <steve_rox> :-P
[22:27] <ShiftPlusOne> DX? A couple of weeks? Someone's spoiled >.>. Back in my day, we'd have to wait for at least several months.
[22:28] <SrRaven> my worst order took 9 weeks
[22:29] <Qjimbo> well sometimes it's delayed if a product is out of stock, but usually it takes 2 weeks from the shipping date
[22:29] <Qjimbo> I am on the west coast of canada, a lot of stuff goes back and forth to hong kong from here so maybe that helps :P

[22:40] <ShiftPlusOne> TronCycle, judging by the 20 seconds of effort I put into finding out what it is, it seems to be somethind under development. I don't see it being released for download anywhere.... but I didn't look hard, so I may be wrong.
[22:41] <plugwash> mmm, memphis the main fedex distribution hub for the US
[22:43] <plugwash> what always gets me is why airmail is so slow, why does it take only a few days for fedex to get something from the US to me and yet it takes the postal service a couple of weeks
[22:45] <Qjimbo> Heh, well USPS is still much better than CanadaPost, at least the costs are reasonable and you get tracking without doubling the price
[22:45] <TronCycle> ShiftPlusOne: Thanks for giving it a look. The search continues, I guess.

[22:48] <steve_rox> :-P
[22:48] <IT_Sean>
[22:49] <SrRaven> Just two more questions,sorted by dumbness
[22:49] <SrRaven> 1) does the pi have audio ?
[22:49] <IT_Sean> Yes
[22:49] <SrRaven> the pi camera*
[22:49] <IT_Sean> Oh, no.
[22:49] <SrRaven> 2) how versatile would the raspberry pi be as a wifi repeater?
[22:49] <ShiftPlusOne> Not very
[22:50] <IT_Sean> ^ that
[22:50] <linuxstb> Well, it can be versatile.
[22:50] <SrRaven> at work we have a mobile enterprise solution which recognizes the wifi by its SSID, Id like the quick and painless option to switch around
[22:50] <SrRaven> and we cant simply mess with our company router
[22:52] <IT_Sean> So... you want to plug your raspi into the company network and then use the raspi as a wifi base station, basically?
[22:53] <IT_Sean> If i caught someone here doing that, i would fire them immediately.
[22:53] <SrRaven> haha
[22:53] <SrRaven> fortune 100 company man :P
[22:53] <IT_Sean> Seriousily.
[22:53] <IT_Sean> That would open up allllll sorts of vulnerabilities.
[22:53] <SrRaven> like?
[22:54] <Qjimbo> You can get cheap wifi repeaters from Acer I think
[22:54] <Qjimbo> or Asus... one or the other
[22:54] <IT_Sean> like you now have a wifi node that may not be secured properly as per company policy...
[22:54] <SrRaven> Meh,was just an idea :P
[22:55] <sney> I would imagine most ESS wifi solutions would have something to prevent that kind of tomfoolery too

[22:55] <sney> something akin to setting a maximum number of hosts on a switchport
[22:55] <SrRaven> so...as the pi camera doesnt have audio....whats a quick and easy (and cheap) solution to get audio
[22:55] <GriffenJBS> usb soundcard
[22:56] <SrRaven> usb soundcards have microphones?
[22:56] * comradegarry (~garry@71.20.80.231) Quit (Quit: leaving)
[22:56] * mickn (~mickn@unaffiliated/mickn) Quit (Quit: ZNC - http://znc.in)
[22:56] <TronCycle> No, but you could hook one up easily.
[22:56] <IT_Sean> some of them have audio gazintas, into which you can plug a microphone
[22:56] <Qjimbo> yep, check DX again, they have USB audio sticks for like... $2, input and output
[22:56] <SrRaven> no direct way to do it?
[22:56] <IT_Sean> you will need a USB sound input device .
[22:56] <IT_Sean> there is no magical sound hole on the raspi.
[22:56] <SrRaven> what about a usb mic?
[22:57] <Qjimbo> oh yeah you need a mic...
[22:57] <IT_Sean> you could use a USB mic.
[22:57] <GriffenJBS> SrRaven: I'm sure you could mine graphite and chop wood, or just go buy a pencil
[22:57] <SrRaven> sounds like work
[22:57] <Qjimbo> http://dx.com/p/usb-2-0-usb-desktop-microphone-black-plug-and-play-230530
[22:57] <IT_Sean> ... it's plugging in a USB device.
[22:57] <IT_Sean> How is that "work"?
[22:58] <SrRaven> was talking about what GriffenJBS said IT_Sean
[22:58] <IT_Sean> Ooooh.
[22:58] <GriffenJBS> maybe I misunderstood, I was a afraid you were asking about a GPIO sound

[23:00] <Qjimbo> sorry to interrupt but random question - is there a guide to the startup scripts in Raspbian, what order they go in etc. ?
[23:01] <SrRaven> me having one =! me wanting to use it
[23:01] <TronCycle> Equals not, eh?
[23:01] <TronCycle> XD
[23:01] <SrRaven> the audio at my workspace will be either a jigsaw,me bitching about it being such hard work or just me cursing
[23:01] <SrRaven> shouldnt need triple digit mic for that
[23:02] <TronCycle> Chances are. Probably just a decent enough mic that the jigsaw doesn't blow everyone's ears out then. :P

[23:14] <TronCycle> Qjimbo: I can't imagine the Raspbian startup scripts being much different from what Debian starts up by default, except for things like Pistore and such, but I could be wrong on that.
[23:14] <Qjimbo> yeah, I just need figure out how to start a very basic X11 environment, then boot a single application at startup
[23:15] <ShiftPlusOne> Raspbian is 'just' debian compiled for the pi.
[23:15] <TronCycle> One of the more important files would be /etc/rc.local there. I've seen it edited for a lot of different projects.
[23:15] <ShiftPlusOne> to do what you want, you need to write your own .xinitrc
[23:16] <Crenn-NAS> Mortvert: eBay should tell you. Postage to Australia was free.
[23:16] <ShiftPlusOne> https://wiki.archlinux.org/index.php/Xinitrc
[23:16] <Qjimbo> Ah... yeah I was actually looking at rc.local - I want to display an options screen with whiptail, then after the user selects something, it starts X and runs the specific program
[23:16] <Qjimbo> would Xinitrc allow this sort of choice? guess I'll have a look at the wiki
[23:16] <Crenn-NAS> Also, getting up 5:30AM each morning sucks!
[23:17] <TronCycle> If you wanted to start just one application, I usually use: startx `which <programnamehere>`
[23:17] <ShiftPlusOne> I would set up automatic login for that and use .bashrc and .xinitrc
[23:17] <Mortvert> Crenn-NAS, yay for response times, i've asked that question over 10 hours ago :P
[23:17] <Qjimbo> ok, cool
[23:17] <ShiftPlusOne> but there are many approaches.... I just wouldn't use services for that.
[23:17] <Crenn-NAS> Mortvert: I have to sleep sometime!
[23:17] <Mortvert> i slept too
[23:18] <TronCycle> ShiftPlusOne has a point there. Probably better not to do system-wide changes for something that small.
[23:19] <Qjimbo> interesting, yeah I guess going too "high up" can unexpectedly break other stuff
[23:19] <ShiftPlusOne> (btw, you need to edit inittab to set up autologin... there are lot of tutorials if you google those search terms)
[23:19] <Qjimbo> hmm for me Raspbian has always autologged in
[23:20] <TronCycle> Autologged in to the shell?
[23:20] <ShiftPlusOne> yeah it uses a DM
[23:20] <Qjimbo> oh, not to the shell, but to the desktop
[23:20] <ShiftPlusOne> but I don't know the specifics of lightdm
[23:21] <ShiftPlusOne> how to configure it to do what you want. The approach I suggested is pretty distro independent. Inittab logs you in, .bashrc launches xinitrc and .xinitrc launches the X programs you need.
[23:21] <ShiftPlusOne> Or configure your own session for lightdm

[23:51] <ShiftPlusOne> Should be enough for everyone =D
