[0:00] <[Saint]> I had to get a trace onto a single pin in the middle of a tiny BGA package once.
[0:00] <[Saint]> That was not a fun day.
[0:00] <Amadiro> that's why you have testpoints on your pcb :P
[0:00] <Helldesk> Amadiro: and on the Pi those points are where?
[0:00] <Helldesk> :)
[0:00] <[Saint]> I didn't have that luxury unfortunately.
[0:01] <Amadiro> Helldesk, no idea, I haven't looked that closely
[0:01] <Amadiro> it probably has some, though...
[0:01] <[Saint]> None relevant for this cause.

[0:20] * aural (~aural@66.233.156.4) has joined #raspberrypi
[0:22] <ShorTie> Hold On
[0:22] <aural> I am getting my first raspberry pi and am new to working with single board microcontrollers and computers. If I buy raspberry pi and a pibow enclosure, will I still be able to use the enclosure whilst also connecting a variety of sensors such as altimeter/barometer/gyroscope/compass/accelerometer/sound/radiation/geiger/light/color/location/gps/etc? Or will I have to connect the raspberry pi to them without using the enclosure? Basically, is it useful for
[0:22] <aural> me to buy an enclosure or maybe not so much?
[0:25] <[Saint]> If you buy from an approved retailer, the box it is shipped in should be fine.
[0:25] <[Saint]> Unless the case you're looking at has GPIO access, I wouldn;t bother.
[0:26] * MidnighToker (~Toker@unaffiliated/midnightoker) has joined #raspberrypi
[0:26] <[Saint]> FWIW - most Android handsets these days should have pretty much all of the sensors you listed above already.
[0:27] * chod (~chod@toy-town.demon.co.uk) Quit (Remote host closed the connection)
[0:27] <[Saint]> And a much better CPU, GPU, and RAM.
[0:27] <[Saint]> But...not exactly useful for bare metal programming.
[0:27] * delugeofspam (sombrero@c-71-232-232-207.hsd1.ma.comcast.net) Quit (Ping timeout: 246 seconds)
[0:28] * SpeedEvil (~quassel@tor/regular/SpeedEvil) Quit (Ping timeout: 245 seconds)
[0:28] <[Saint]> Geiger counter might be an issue with an Android handset, but you could hack one up really easily if the camera on the device has a decent sensor.
[0:29] <shiftplusone> 'morning
[0:29] * delugeofspam (sombrero@c-71-232-232-207.hsd1.ma.comcast.net) has joined #raspberrypi
[0:29] <[Saint]> The Geiger counter application I use is pretty accurate, disturbingly.
[0:30] <[Saint]> But it does involve blacking out the camera, making it pretty much useless as...y'know, a camera. :)

[0:38] <aural> I am considering to purchase from adafruit.com, and to my understanding, it seems they custom design a lot of their own hardware components too. Though, despite them, are any other retailers worthy to consider purchasing raspberry pi and variety of other compatible hardwares from?
[0:40] <ShorTie> kinda depends on what cha want and how fast you want it

[0:51] <aural> ShorTie: mm, could you elaborate? e.g. perhaps there are different products available at different retailers? thus, no single reseller/retailer that has everything?
[0:52] <ShorTie> ebay has a good selection at a good price for most things, but just might have to wait a month for it
[0:52] <[Saint]> Its the wrong time of year to be ordering from eBay.
[0:52] <[Saint]> You'll wait forever.

[0:59] <SpeedEvil> Not yet.
[0:59] <SpeedEvil> It hasn't really started to slow down IME.

[1:03] * factor (~factor@wsip-70-183-48-203.ok.ok.cox.net) Quit (Ping timeout: 252 seconds)
[1:04] <[Saint]> ...what the?!?
[1:04] <[Saint]> Why Gus, why? Why'd you kill Victor?
[1:04] <[Saint]> ...and why am I in the wrong channel?
[1:05] * Benguin is now known as Benguin[ZzZ]

[1:06] * Mortvert (~Mortvert@reddit/operator/mortvert) has joined #raspberrypi
[1:07] <shiftplusone> To make a point, [Saint]... to make a point.
[1:08] <[Saint]> What point? "Mess with me, and I'll kill 'ya?"...he can't exactly do that with Walt and Jesse, and he knows that, and they do too.
[1:09] <[Saint]> Victor needed to be disposed of, sure, but I don;t understand why it needed to be Gus that did it, and why in sch a brutal fashion.
[1:10] <[Saint]> Walt did that whole "You kill me, you have nothing. You kill Jesse, you don't have me." thing, and it was pretty clear then that Gus knew the pair were pretty much untouchable.
[1:10] <shiftplusone> I don't really remember the circumstanced, since it was a while back, but yeah that was a... memorable scene.
[1:11] * taza (~zap@unaffiliated/taza) has joined #raspberrypi
[1:11] <[Saint]> I never watched it, and managed to avoid spoilers, when it was airing.
[1:11] <[Saint]> I'm going back and watching it now.
[1:11] * busla (~busla@dsl-149-60-149.hive.is) Quit (Remote host closed the connection)
[1:12] <shiftplusone> Yeah, I have a counter argument to what you said, but it would involve a spoiler, so I'm keeping quiet.
[1:12] <[Saint]> Thankyou.
[1:12] * Armand (~martin@185.24.99.51) Quit (Quit: Leaving)
[1:12] <[Saint]> Its appreciated.
[1:13] * factor (~factor@wsip-70-183-48-203.ok.ok.cox.net) has joined #raspberrypi
[1:13] <[Saint]> I'm only up to S04E08, but that's not bad going for three days. :)
[1:14] <[Saint]> Been havin' my bad self a BB marathon.
[1:16] <shiftplusone> That's probably the smart way of doing it. That 1 episode per week thing and breaks between seasons is quite annoying
[1:17] * hyperair (~hyperair@ubuntu/member/hyperair) Quit (Ping timeout: 264 seconds)
[1:17] <[Saint]> I find I do that with a lot of series.
[1:17] <[Saint]> I've done a fine job avoiding The Walking Dead too
[1:18] <[Saint]> (that one is nice because it doesn't really matter if you know the storyline from the graphic novels, as they've deviated from it so wildly)
[1:18] * dreamon (~dreamon@unaffiliated/dreamon) Quit (Remote host closed the connection)
[1:19] <shiftplusone> I watched one episode of that a while back and it was pretty 'meh', but it does seem to be quite popular now. So if I misjudged, it might make sense to watch it your way.
[1:20] <[Saint]> http://www.free-tv-video-online.me/internet/the_walking_dead/ <-- go nuts. :)
[1:21] <shiftplusone> don't have the interest yet.

[1:23] <[Saint]> That's a great site. Updated regularly to combat the multiple DMCA takedown requests.

[1:29] * dreamon (~dreamon@unaffiliated/dreamon) Quit (Ping timeout: 246 seconds)
[1:33] <aural> Is there a way that I can pay to watch it so that I can guarantee that the MPAA will get at least 98% of the money that I pay?
[1:34] * Geniack (~Geniack@unaffiliated/geniack) has joined #raspberrypi
[1:35] <aural> Or at least benefits specifically greedy, selfish psychopathic humans more so than those that are not greedy or selfish?
[1:35] <aural> There must be at least one service provider offering such quality or service that is dependable, reliable and I can trust/count on.
[1:36] * JMichaelX (~james@unaffiliated/jmichaelx) has joined #raspberrypi
[1:36] <hybr1d8> Sony
[1:36] <ParkerR> aural, Netflix
[1:36] <ParkerR> Hulu
[1:36] <aural> I need evidence.
[1:36] <hybr1d8> nah - those will give some of the money to the actual artists/performers
[1:37] <aural> right
[1:37] <aural> that is unacceptable
[1:37] <ParkerR> Evidence of what? Those support the networks. Hulu has NBC and shit, Netflix has some others
[1:37] * Geniack_ (~Geniack@unaffiliated/geniack) Quit (Ping timeout: 245 seconds)
[1:37] <ParkerR> Unacceptable for the performers to egta cut?
[1:37] <ParkerR> *get a
[1:37] <hybr1d8> I think you may have missed the sarcasm ;)
[1:38] <aural> Maybe it would be easiest if those in charge of the related organizations were to reveal a particular bank account or other way to fund them directly so that I can rest assured that my money is going to those most deserving of the money.
[1:39] <aural> alternatively
[1:39] <aural> in a nonsarcastic fashion
[1:40] <aural> it would be incredibly beautiful and awesome if I could purchase something, and relatedly could see exactly where all the money goes to, who it is distributed to, etc.
[1:40] <aural> and not just on a small scale, but in a large scale too
[1:40] <hybr1d8> Something like 'humble bundle' for media
[1:44] * jaytk (~jaytk@108-232-157-80.lightspeed.tukrga.sbcglobal.net) has joined #raspberrypi
[1:45] <shiftplusone> If content producers choose to work with MPAA it's their choice, so I wouldn't pretend that people pirate these shows for ethical reasons. O_o

[2:01] * Mortvert (~Mortvert@reddit/operator/mortvert) has joined #raspberrypi
[2:02] <aural> btw, why is Adafruit.com not listed as one of the retailers to buy a raspberry pi from on http://raspberrypi.org/ website?
[2:02] <shiftplusone> aural, because they are not an official distributor, they don't make them or anything.
[2:03] * Jeebiss (~Jeebiss@2602:306:bc31:5920:f1c6:378c:ac97:6cc) Quit (Ping timeout: 240 seconds)
[2:03] <shiftplusone> They just buy in bulk from the distributors and sell them.
[2:03] <aural> shiftplusone: hmm, that seems strange to me because they seem to have a LOT more raspberry pi-related hardware than any of those other official distributors.
[2:03] <aural> at least for the ones in English language.
[2:03] <shiftplusone> well, that's how they make money
[2:04] <shiftplusone> RS and Farnell have been around for way longer than the pi and the pi is only a slight portion of their business.
[2:04] * Syliss (~Home2@dpncorp1.digitalpath.net) Quit (Quit: Syliss)
[2:05] <kickstarrabbit> any good linux distros for pi
[2:05] <kickstarrabbit> i tried all the ones avail at the main site
[2:05] <shiftplusone> raspbian and arch are the well maintained distros.
[2:05] <shiftplusone> you can check the elinux wiki for a complete list

[2:07] <shiftplusone> customized raspbian... going for crunchbang feel
[2:09] <[Saint]> I'm not going to name any names, but the people who decided it'd be fun to PM me spoliers - I hope you choke on a phallic object and die.
[2:10] * shiftplusone was 99% sure that would happen.
[2:10] <[Saint]> It sure would be a shame if I decided to leverage the computing power at my disposal to "accidentally" bump you off the internet now wouldn't it? :)
[2:10] <[Saint]> So, lets play nice.
[2:11] <ShorTie> oh, that ain't no fun
[2:12] * l4rz is now known as Lars|afk

[2:12] <shiftplusone> There is that
[2:13] <[Saint]> ...and where did that happen?
[2:13] <SpeedEvil> Linking to copyright infringing content.
[2:14] <ReggieUK> hi all
[2:14] <[Saint]> Depending on your locale, that's perfectly legal, like here - so, ...howabout no.
[2:14] * jaytk (~jaytk@108-232-157-80.lightspeed.tukrga.sbcglobal.net) Quit (Remote host closed the connection)
[2:14] <shiftplusone> 'morning Reggie.
[2:14] <ReggieUK> how about we end this conversation right here and everybody moves on :)
[2:15] <[Saint]> I just disliked the implication that I somehow deserved it...it was very asshatish.
[2:15] <ReggieUK> like I said, lets end the conversation there and all move on :)
[2:16] <ReggieUK> seems teh best way, no blame, just movin on......

[2:55] <happygilmoregent> raspberrypi.org shows where to find pi why does it only list two websites
[2:57] <shiftplusone> happygilmoregent, because those are the only two official distributors/manufacturers.
[2:57] <happygilmoregent> anyone else here
[2:57] * user82 (~user82@unaffiliated/user82) Quit (Ping timeout: 246 seconds)
[2:57] <shiftplusone> the rest are resellers
[2:57] * shawn-p (~Shawn@205-178-125-247.c3-0.stk-ubr2.chi-stk.il.cable.rcn.com) has left #raspberrypi
[2:58] <happygilmoregent> ok
[2:59] <happygilmoregent> do the resellers create issues wiht quality
[2:59] <shiftplusone> no, since they get them from the manufacturers.
[3:00] <happygilmoregent> ok
[3:01] <shiftplusone> The raspberry pi foundation licenses the design out to RS and Farnell, RS and Farnell actually make them. The resellers buy from RS or Farnell (as you would), and sell it. It lets them bundle their own products with the pi and such.
[3:02] <happygilmoregent> so there would be amazon kindle application on pi if bought on amazon?
[3:03] <shiftplusone> eh? No, that's not what I meant. I am talking about the sort of thing that adafruit does, like sell breakout boards and sd cards and so on
[3:03] <chithead> the pi has no storage, so there cannot be any preinstalled application
[3:04] <happygilmoregent> oh ok
[3:05] * GentileBen (~RaycisCha@cpc5-lutn10-2-0-cust681.9-3.cable.virginm.net) Quit ()
[3:10] <happygilmoregent> are the versions that come on the 8GB OS card images like initrd?
[3:10] <shiftplusone> I am having a hard time parsing that question
[3:11] <happygilmoregent> on the 8GB SD card it says it comes with variations of raspberrypi OS(raspbian etc) once you have selected the variation you are going to run with can you remove the others
[3:12] <shiftplusone> I am going to assume you're talking about NOOBS. Why do you want to do this? To avoid the menu popping up or to save disk space?
[3:13] <happygilmoregent> save space
[3:13] <shiftplusone> In that case, either use the offline version of NOOBS, or raw disk images.
[3:13] <ShorTie> then just the image to the card

[5:12] * oldtopman (~oldtopman@unaffiliated/oldtopman) Quit (Quit: *pouf*)
[5:13] <VlperX> why are both stupid, shiftplusone?
[5:13] <sney> the raspberry pi does not run at a temperature that requires a heatsink.
[5:13] <shiftplusone> they are unnecessary and ineffective. The topic has been covered to death on the forum.
[5:13] <sney> putting one on would be purely aesthetic
[5:14] <VlperX> it gets kinda hot. I just imagine it'd be better for prolonging the life
[5:14] <shiftplusone> the gpu/cpu chip is not what's going to fail first
[5:14] <sney> in the aesthetic regard, it's a question of "which do you like better, orange or light grey"
[5:14] <VlperX> so mounting a fan to the case would be just as stupid?
[5:15] <shiva_inu> Would the pi get substantially hotter in a case? Enough to matter?
[5:15] <sney> it's a SoC designed for set top boxes, and in those it wouldn't have a heatsink either. vents, maybe, but not much emphasis on them
[5:16] <shiftplusone> a fan makes some sense
[5:16] <VlperX> how so?
[5:16] <VlperX> what about a heatsync + fan?
[5:17] <shiftplusone> If you slap on a heatsink, you're cooling the RAM.
[5:17] <shiftplusone> The GPU is underneath, and the thermal coupling is poor
[5:17] <shiftplusone> so the effect on the gpu is minimal
[5:17] <VlperX> CPU, you mean?
[5:17] <shiftplusone> it's both
[5:17] <VlperX> ah
[5:17] <shiftplusone> the cpu and gpu is in the same package
[5:17] <VlperX> i thought that was the CPU with the RAM ontop?
[5:17] <VlperX> but you said gpu
[5:17] <VlperX> wait what
[5:17] <shiftplusone> it's the SoC (GPU+CPU) under the RAM.
[5:18] <VlperX> oh i thought the other chip was the gpu
[5:18] <shiftplusone> I think you might be talking about the lan/usb chip
[5:18] <VlperX> probably
[5:19] <shiftplusone> What temperature is your pi running at?
[5:19] <VlperX> haven't measured it
[5:19] <VlperX> but probably 40-50
[5:19] <shiftplusone> which would be very cold
[5:20] <shiftplusone> I'd expect it to be in the 60s, which is getting slightly warm. 80 is starting to get hot, so the chip will cool itself down by turning off all overclocking.
[5:20] <shiftplusone> if you somehow manage to get to 90, it will just shut down.
[5:20] <VlperX> I see
[5:21] <shiftplusone> not because 90 is a high temperature for it and it's going to get damaged, but because it indicates something else might be wrong, since it shouldn't get that hot under normal operation.
[5:21] <VlperX> if it resets when plugging in a usb device, does that mean it's not getting enough powera/
[5:21] <VlperX> ?
[5:21] <shiftplusone> that happens due to high resistance of the internal traces and lack of decent capacitors on usb input
[5:22] <owen_> yes
[5:22] <shiftplusone> so the surge of current causes the voltage to drop and the pi to reset
[5:22] <sney> it seems that usb devices get initialized at full power even if they drop down immediately, and that's enough to reset it
[5:22] <shiftplusone> you can get a different supply, but that will still happen.
[5:22] <VlperX> hm
[5:22] <sney> powered hub is the answer anyway
[5:22] <owen_> I made my own power supply, 2A, no reboots
[5:22] <shiftplusone> There's also an easy hardware mod you can do.
[5:22] <shiftplusone> owen_, microusb or gpio?
[5:23] <owen_> micro usb
[5:23] <shiftplusone> no modification to the hardware?
[5:23] <shiftplusone> and you're talking about high power wifi sticks and such?
[5:24] <owen_> no, its just a pwer supply with a low internal resistance
[5:24] <shiftplusone> the resistance of the traces is still quite significant though
[5:24] <shiftplusone> so I guess with a generic supply plus the traces, it adds up.
[5:25] <VlperX> i'm using a HTC 240v > usb output 1A
[5:25] <shiftplusone> wheres a low ESR supply or some bypass wires will fix the issue.
[5:25] <owen_> personnally, I think a big capacitor across the supply might fix most reboots, but it's no very convenient
[5:25] <shiftplusone> owen_, http://triffid-hunter.no-ip.info/101_0120.JPG
[5:26] <shiftplusone> that has the wires and the caps, but another guy on here got away just by adding the wires.
[5:27] <owen_> wonder why D17
[5:28] <owen_> or is that a cap?
[5:28] <shiftplusone> first point after the polyfuse
[5:28] <shiftplusone> nearest to the supply without bypassing input protection
[5:28] <shiftplusone> it's not a cap, it's a spike killing diode thing (forget the name)
[5:29] <shiftplusone> TVS diode
[5:29] <owen_> ok, reverse voltage protection diode
[5:29] <shiftplusone> nuh, not reverse voltage. It's in parallel. http://www.littelfuse.com/~/media/Electronics/Datasheets/TVS_Diodes/Littelfuse_TVS_Diode_SMBJ_Datasheet.pdf.pdf

[9:10] <shiftplusone> does the read fail or just the write?
[9:10] <heckran> just write
[9:10] <heckran> I can read it
[9:10] <shiftplusone> as root?
[9:10] <heckran> yea
[9:11] <shiftplusone> can you write other files in /etc ?
[9:11] <heckran> yes
[9:11] <shiftplusone> ....well that's just odd O_o
[9:11] <shiftplusone> and there's no error other than that it cannot write to it?
[9:11] <heckran> very
[9:12] <heckran> that's only error i get
[9:12] <heckran> unless there's a different error log file for that
[9:12] <shiftplusone> maybe, take a look in /var/log, but I highly doubt it.
[9:13] <shiftplusone> make a backup of the file. What if you rm -f it?
[9:13] <heckran> let me try
[9:14] <heckran> rm: cannot remove `/etc/shadow': Operation not permitted
[9:14] <shiftplusone> try strace rm /etc/passwd and pastebin the lines around the point where it fails

[9:20] <shiftplusone> I wonder if that's the line of interest.
[9:20] <shiftplusone> (A bit of a disclaimer, I have no idea what I am talking about.) Looks like an issue with the sd card to me.
[9:21] <shiftplusone> google returns plenty of results with people complaining about getting the same error on files that exist
[9:22] <heckran> hmm
[9:23] <shiftplusone> or not... I have no idea really, so I shouldn't guess.
[9:23] <heckran> is there a way to test my sd-card
[9:24] <shiftplusone> Did you do anything strange like mess with your repo sources file?
[9:25] <heckran> never touched those
[9:25] <shiftplusone> outpus of ls -la /etc/passwd ?
[9:26] <shiftplusone> Ooh, can you try writing to the file from another computer that's not a pi?

[9:28] <heckran> sure, but i think something broke after that previous command unknown uid 1001: who are you?
[9:28] <shiftplusone> that command wouldn't break things, but that does indicate your system is borked in more ways than one.
[9:29] <Triffid_Hunter> unlinkat(AT_FDCWD, "/etc/passwd", 0) = 0 <-- that says unlink succeeded
[9:29] <shiftplusone> yeah, so what gives?
[9:29] <Triffid_Hunter> man rm: RETURN VALUE On success, unlinkat() returns 0. On error, -1 is returned and errno is set to indicate the error.
[9:29] <shiftplusone> oh... yeah
[9:30] <shiftplusone> quick, move the backup back if you can D=

[9:30] <heckran> jeez
[9:30] <shiftplusone> So what's up with "rm: cannot remove `/etc/shadow': Operation not permitted"
[9:30] * dreamon (~dreamon@unaffiliated/dreamon) has joined #raspberrypi
[9:31] <Triffid_Hunter> llseek(0, will always fail since 0 = stdin and you can't seek streams.. no idea what's going on there.
[9:31] <shiftplusone> Well, that's what happens when you take horrible advice I guess... you accidentally delete important system files >_<
[9:31] <Triffid_Hunter> shiftplusone: well the straced one doesn't say that
[9:31] <shiftplusone> Why would running rm directly fail while running it via strace succeed?
[9:31] <Triffid_Hunter> no clue
[9:31] * aural (~aural@66.233.156.4) has joined #raspberrypi
[9:32] <Triffid_Hunter> why are we deleting /etc/passwd in the first place?
[9:32] <aural> What is the largest size sd card that the raspberry pi supports?
[9:32] <Triffid_Hunter> aural: 2TB as far as I know
[9:32] <Triffid_Hunter> don't think there's any reason for it to be limited by anything other than the SD communication protocol
[9:32] <shiftplusone> Triffid_Hunter, He can't write to /etc/passwd even though all the permissions are fine, the system is not RO, so I was going for a last resort sort of thing and seeing whether he can delete and restore it.
[9:33] * Coffe (~mrGreen@nat.basefarm.se) has joined #raspberrypi
[9:33] <shiftplusone> though I suppose strace on a simple write that wouldn't break things would've been the smarter thing to do.
[9:33] <Triffid_Hunter> strace on an append would have been fine
[9:33] <heckran> well i got a backup of passwd. how can i move it back to /etc/ when I can't do any commands
[9:34] <shiftplusone> from another computer, I suppose. Would it work with init=/bin/bash in cmdline, Triffid_Hunter ?
[9:35] <aural> Also, the raspberry pi supports only one gpio connection right? Is it possible to daisy chain breakout boards?
[9:35] <Triffid_Hunter> shiftplusone: depends where the problem is
[9:35] <Triffid_Hunter> heckran: sure there's nothing interesting in dmesg | tail -n200 ?
[9:35] <shiftplusone> Triffid_Hunter, well right now the problem is that he is missing an /etc/passwd and can't restore it.
[9:35] <shiftplusone> Triffid_Hunter, an earlier dmesg from him http://pastebin.com/3qXcgTkY
[9:35] <aural> hmm, maybe I am using the wrong terminology
[9:36] <aural> What are the boards called that sensors, leds, buttons, etc can be connected to?
[9:36] <shiftplusone> aural, yeah, that didn't quite make sense.
[9:37] <shiftplusone> You don't need a special board for that
[9:37] <aural> hmm, even if I want to connect a lot of them?
[9:37] <Triffid_Hunter> aural: arduino :P
[9:37] <shiftplusone> depends on what 'a lot' means
[9:37] * cccyRegeaneWolfe (~cccyRegea@210.23.18.112) has joined #raspberrypi
[9:38] <shiftplusone> there are gpio expanders and buffer chips which will help you get around certain limitations. But are you after something like a piface?

[9:39] <aural> For now I am expecting to learn

[9:43] <shiftplusone> heckran, that's the sure way. There's another one, but I am not 100% sure it will work and it's not that much quicker anyway.
[9:43] <shiftplusone> heckran, sorry by the way, deleting it was terrible advice.

[11:21] <shiftplusone> or ADC, DACS, relays and so on
[11:22] <shiftplusone> oh and the AVR
[11:22] <shiftplusone> so with a breadboard, you'd have to provide these yourself, if necessary.
[11:22] <aural> mm
[11:22] <gordonDrogon> yup - breadboard - blank canvass, Gertboard, Gertduino - a ready made system.
[11:23] <gordonDrogon> (+piface, etc.)
[11:23] <aural> For playing around and tinkering, and not soldering anything permanently, and especially for learning purposes, perhaps a breadboard may be more useful than a gertboard or piface, right?
[11:24] <shiftplusone> absolutely
[11:24] <aural> cool
[11:24] <shiftplusone> since with a breadboard you have to learn
[11:24] <aural> yay, that's what I'd like to do :)
[11:24] <shiftplusone> with these boards you can plug stuff in, copy and paste some source code and it just works
[11:25] <aural> and my question earlier, about daisy chaining, the one that didn't make sense. To connect a breadboard to a raspberry pi, would that require a gpio cable?
[11:26] <shiftplusone> It would require something. It's up to you how you want to do it.
[11:26] <aural> mm
[11:26] <shiftplusone> My first "gpio cable" was an ide cable with one end cut off and the wires tinned.
[11:28] <shiftplusone> adafruit's pi cobbler is the cleanest solution I have seen

[11:50] <aural> In that video, those tiny hardware pieces inserted into the breadboard to the right of the led lights, are those called transistors, diodes, or something else?
[11:51] <aural> 3 at top-right corner, 2 at bottom-right
[11:51] <shiftplusone> aural, sorry, was afk. What time stamp?
[11:51] <aural> viewable throughout the entire video
[11:51] <aural> the latter
[11:51] <shiftplusone> ah ok
[11:52] <shiftplusone> resistors
[11:52] <aural> ah right
[11:52] <shiftplusone> they limit the current to make sure the ports don't mess up
[11:52] <aural> I meant resistors, but got the name wrong and was confused :)
[11:52] <VlperX> can the yellow RCA port be used for a coax IN ?
[11:52] <shiftplusone> VlperX, nope.
[11:52] <VlperX> or is it just an output?
[11:53] <VlperX> so how might I plug a TV antenna into it?
[11:54] <shiftplusone> using one of those usb tuners
[11:54] <shiftplusone> don't know how well they perform on a pi
[12:02] <ShorTie> if you just use that usb tuner locally it most likely be ok, but if you start trying to push it out at the same time problems might occure

[12:49] <aural> I am not familiar with resistors and the variety that exist, nor which ones I may need or use in future projects.
[12:50] <shiftplusone> I'd recommend a kit of assorted resistors from ebay

[14:37] <clever> Jck_True: using stty, you can disable the local echo stuff in a tty
[14:37] <clever> Jck_True: then what you type simply never appears
[14:38] <clever> the code within your client is then free to display what you type anywhere it wants
[14:38] <Jck_True> Ohh
[14:38] <Jck_True> But then i would have to manually refresh the entire screen
[14:38] <Jck_True> On each charecter
[14:39] <clever> thats where the terminal controls to seek to a position come in
[14:39] <clever> you jump down to the text input box, then print a few characters there
[14:39] <clever> ncurses is just a library to automate all of that and make it simpler to do
[14:39] <Jck_True> Will that make the rest of the window scroll?
[14:39] <Jck_True> (I just want the lowest line to remain editable

[14:40] <clever> run a normal irc client like irssi, and then use your code to make a irc server
[14:40] <Jck_True> Strange that I can't find a tool that simply launches a program and splits STDIN/STDOUT into 2 windows
[14:41] <clever> ive made such a thing before, but its not pretty

[14:42] <Jck_True> Worth a try
[14:42] <Jck_True> Can't really be bothered to go through all my PHP code to fix my echo'es
[14:42] <clever> and once you add fifo's like that, its no longer a tty, so you cant use tty control codes

[19:02] <Yugnoswam> Other question: I bought a USB Power Hub seeing as the pi itself can't power my HDD through USB
[19:03] <ShorTie> �k�� ��K��
[19:03] <Yugnoswam> Plugged the USB Hub into the wall and pi and the pi loaded up, it was taking power through USB
[19:03] <IT_Sean> It does that.
[19:03] <Yugnoswam> Aswel as the normal power supply
[19:03] <Yugnoswam> Does that make a differnce?
[19:03] <IT_Sean> As log as it's stable being backfed, then no, it doesn't matter
[19:03] <ShorTie> ya, cheapy usb hubs do that
[19:03] <IT_Sean> The hub is not SUPPOSED to do that, as it violates the USB spec, but, that's what happens when you outsource to china.
[19:04] <Yugnoswam> can't complain for �3 tbf
[19:04] <Yugnoswam> Hopefully it won't melt the pi or something XD

[19:46] * felipealmeida (~user@177.98.67.55) has joined #raspberrypi
[19:46] <gordonDrogon> what to do is put the Pi with the camera and use 2-3m of ethernet cable...
[19:47] <MrVector> That might not be possible due to space constraints
[19:47] <MrVector> Do you think it's too far?
[19:47] <IT_Sean> MrVector: 2 to 3 meters will be beyond the cable limit of the camera, as per my understanding.
[19:48] <MrVector> Oh, I've been Googling this, just found http://www.bitwizard.nl/catalog/product_info.php?products_id=146
[19:48] <IT_Sean> HoloPed: there is just the one camera module.
[19:50] <MrVector> That seems to work

[19:52] <MrVector> Any opinions on that kit? :-)
[19:54] <IT_Sean> MrVector: I stand corrected. The camera module cable has been reported to work over distances of up to 4 meters.
[19:54] <Sonny_Jim> Erm, just make one yourself
[19:54] <IT_Sean> ymmv, however.
[19:54] <MrVector> Care to cleary, Sonny_Jim? :)
[19:54] <Sonny_Jim> Buy some ribbon cable, IDC connectors and a male-male connector
[19:54] <Sonny_Jim> Unless I'm missing something
[19:55] <MrVector> That is probably what I would do, I was just curious whether it was possible at this point :)
[19:55] <Sonny_Jim> Should come to about half what they are charging
[19:56] * Tonbi_ko (~rrr@zenmai.org) Quit (Ping timeout: 248 seconds)
[19:56] <IT_Sean> the FAQ indicates that it has been shown to work at up to 4m. ymmv, however.
[19:56] <Sonny_Jim> You don't really need the IDC tool, you can do it yourself with a vice
[19:56] <MrVector> ymmv?
[19:56] <Sonny_Jim> Your Mileage May Vary
[19:56] <MrVector> Ah
[19:57] <MrVector> Haven't heard that one before :)
[19:57] <gordonDrogon> it's a very high speed digital interface, so make sure you use good cable.
[19:57] <MrVector> Thank you for the advice
[19:57] <pwillard> Beyond 15 inches... I would assume I would start to lose valuable signal quality.
[19:58] <Sonny_Jim> Well, if that kit includes reasonable postage it might be better to get them from there. A lot of electronic places have minimum order values
[19:58] <MrVector> I'm not expecting 1020 at that distance, I can live with a slight loss in quality
[19:58] <pksato> "The physical layer of CSI is based on signaling scheme called SubLVDS, which is current mode differential low voltage signaling..."
[19:59] <MrVector> Good to know that it works though
[20:00] <Sonny_Jim> So what's the benefit of the camera module over a standard USB camera?
[20:00] <clever> doesnt eat up usb bandwidth
[20:01] <IT_Sean> the camera module is controlled directly from the GPU. A bog standard USB camera would not be. Also... that^ doesn't eat us USB bandwidth.
[20:01] <clever> gpu can encode the video directly to h264 without having to memcpy frames arround

[20:02] <gordonDrogon> if it's differential, then you ought to use twisted pairs for the signals...
[20:02] <clever> your ethernet is also usb based
[20:02] <MrVector> it will be a standalone device with no ethernet
[20:03] <gordonDrogon> at least I remember using some silly expensive twisted pair cable for diff-scsi way back when the disks were required to be some 5 metres away from the servers...
[20:03] <pwillard> ^^
[20:04] <MrVector> Hmm, displays are really expensive
[20:04] <clever> gordonDrogon: i believe twisted pairs improves the signal quality, letting you get more distance
[20:04] <clever> but its optional at much shorter distances
[20:04] <pksato> that is min. lines/wires need to connect can. module? (15 is total of pins)
[20:05] <clever> for example, ethernet is twisted pair, and ive heard of one guy that used the wrong pairs for one of his cables
[20:05] <clever> it worked perfectly fine, until he turned on the xmas lights
[20:05] <clever> the ethernet wire was strung up on the same hooks as the lights

[22:30] <Sonny_Jim> f00bar80: I think your question has already been answered
[22:30] <hosler> is there ever an instance where current is the cause and voltage is the effect?
[22:31] <Sonny_Jim> I was always taught that voltage was the 'amount of them' and current was how much charge each one of them carried
[22:31] <Sonny_Jim> No idea if that's a good model
[22:31] <PigFlu> each one of what
[22:31] <Sonny_Jim> Well, 'them'
[22:31] <PigFlu> -_-
[22:31] <Tachyon`> electrons?
[22:32] <Sonny_Jim> I was trying not to use that word
[22:32] <Tachyon`> why?
[22:32] <pksato> hosler: on a generator?
[22:32] <Tachyon`> it's not like voldemort
[22:32] <Sonny_Jim> As I said, not sure how handy that 'thought model' was
[22:32] <PigFlu> idk
[22:33] <PigFlu> voltage is just a potential difference. if u have many electrons on one side, and few on the other, the many want to cross sides
[22:33] <PigFlu> the more they are, the faster they go
[22:33] <Sonny_Jim> Sure
[22:33] <PigFlu> or something
[22:33] <Sonny_Jim> And current is how much 'energy' each one of those electrons have
[22:34] <Sonny_Jim> JoshMcCullough: One pin supports hardware PWM
[22:34] <PigFlu> well

[22:35] <PigFlu> each electron has the same charge
[22:35] <Sonny_Jim> Aw yeah
[22:35] <Sonny_Jim> There's a constant for that, isn't there?
[22:36] <Nefarious___> Current is just the flow of electrons
[22:36] <Nefarious___> -1
[22:37] <XMLnewbi> wierd, I got going on a clean raspbian build with the gui, I was able to get the info in, and got assigned an IP and even ssh'd in. yet im not online. browsers wont work nor update. im on a mifi hotspot

[22:44] <sney> XMLnewbi, no route to the internet?
[22:46] <hosler> how about this: voltage = car, resitance = speed bump, and current is how fast you go over speed bump. so bigger the car, the less you slow down for speed bump.
[22:46] <hosler> would that be a correct analogy?

[23:52] <Sonny_Jim> Not a great variable name as it's hard to see what it's for
[23:53] <PigFlu> uh, yea, sorry. its an integer between 0 and 100
[23:53] <Sonny_Jim> I mean, for (i = 0;i++ ;i < MAX_LOOP) is ok as it's fairly obvious what i is for (if you can excuse the pun)
[23:53] <PigFlu> or rather, between 0 and led_freq
[23:53] <PigFlu> as to give the intensity
[23:53] <Sonny_Jim> Oh ok
[23:53] <PigFlu> sort of like the duty cycle
[23:53] <Sonny_Jim> led_intensity might be a better name for it
[23:53] <PigFlu> yea im lazy
[23:54] <Sonny_Jim> Most IDE's will allow you to autocomplete so you don't need to type the whole name out each time
[23:54] <PigFlu> i know, im using xcode
[23:54] <PigFlu> also, the cycle_ish variable is how many times it should toggle the led, during its 100 iterations
[23:55] <PigFlu> i named it cycle_ish, because its rounded down to the nearest integer, lol
[23:56] <PigFlu> wait no. during the "led_freq" iterations, it shold toggle the led every cycle_ish'th iteration
[23:56] <PigFlu> so if i want a 25% intensity, i = 25, and cycle_ish = 4
[23:56] <PigFlu> it will then turn on the led every 4th period
[23:57] <PigFlu> but for i = 1, it should only blink the led once every second. but it blinks roughly twice, which i dont understand at all. in fact, all frequencies are doubled
[23:57] <Sonny_Jim> tbh it seems overly complicated for what it does
[23:58] <PigFlu> maybe so, but that doesnt explain my problem
[23:58] <Sonny_Jim> true
