[0:03] <dansan> Hurray! I got my new toys today! The MCP2210 breakout board and a bunch of used KIS3R33S! Still waiting for my new soldering iron though :(
[0:03] <OpenSys> Temp: 21.6, RH: 66.3%
[0:04] <OpenSys> gordonDrogon, its all new, but makes sense
[0:05] <OpenSys> interferences in SPI channel VS I2C
[0:05] <OpenSys> remove all com wire
[0:05] <OpenSys> remove all com wires
[0:05] <OpenSys> and works

[0:10] * tonyhughes (~tonyhughe@ Quit (Client Quit)
[0:10] * tonyhughes (~tonyhughe@ has joined #raspberrypi
[0:11] <tonyhughes> Just installed Raspberry Asterisk - wow great
[0:11] <tonyhughes> Cant wait for my SPA3102 to arrive so I can trunk my landline
[0:12] <tonyhughes> Ironically, my landline is delivered via SIP, but over my ISPs ATM link, not IP on the DSL connection. I have hacked the router and found all the SIP settings, but impossible to get them working from a device external to the router :(
[0:13] <buzzsaw> my pi is here
[0:13] * gyeben (~gyonkiben@dsl51B61186.pool.t-online.hu) has joined #raspberrypi
[0:13] <Triffid_Hunter> tonyhughes: are they accessible if you put it in bridge mode and then run rp-pppoe on the pi or something like that?
[0:13] <buzzsaw> and it is sexy
[0:15] <tonyhughes> No, as soon as you are on PPPoA, their network physically won't route the private FQDN (or IP) of the voice server.
[0:15] <echelon> ok, how long should this last for the rpi? http://www.amazon.com/dp/B008RZYN8A
[0:16] <tonyhughes> echelon, 1 hour and 57 minutes
[0:16] <echelon> :/
[0:16] <tonyhughes> Educated wild guess
[0:16] <echelon> what can i get that will last me 2 weeks?
[0:17] <tonyhughes> Erring on the side of a buffer
[0:17] <ShiftPlusOne> Why is the educated wild guess to specific?
[0:17] <ShiftPlusOne> *so
[0:17] <buzzsaw> how many amps does the pi take?
[0:17] <tonyhughes> Why is 1h57m any more specific than 2h ? ;-P
[0:17] <Armand> tonyhughes!
[0:17] <tonyhughes> Armand!
[0:18] <ShiftPlusOne> If you're not using USB, you may get up to 4 hours, but I think that's unlikely
[0:18] <Armand> I'm peeved.. I need to source 60 USB ports. :/
[0:18] * stepho (~stephram@ppp59-167-121-22.static.internode.on.net) has joined #raspberrypi
[0:18] <tonyhughes> echelon, this will meet/exceed your needs http://www.tradetested.co.nz/50kva-diesel-silent-industrial-generator-with-battery.html
[0:19] * Caribou| (~Caribou@ Quit (Quit: Leaving)
[0:19] <tonyhughes> Wait... no... its 12v
[0:19] <tonyhughes> You need 5v
[0:19] <Triffid_Hunter> echelon: rpi uses about 3.5w, let's call it 5w for engineering overhead. 5 watts * 2 weeks is about 6Mj, or 1680Wh. At 12v, that's 140Ah
[0:20] <ShiftPlusOne> echelon, You shouldn't trust these calculations, since it's not really an accurate way to figure these things out, but if you run the pi at 700ma (worst case scenario), then 1860/700=2.65 hours.
[0:20] <Triffid_Hunter> echelon: so a marine deep cycle battery will run it for 2 weeks, get an LM2596 buck converter from ebay :)
[0:20] <ShiftPlusOne> in reality the pi uses maybe about 400-450
[0:20] <ShiftPlusOne> (mA)
[0:21] <echelon> :/
[0:21] <ShiftPlusOne> Triffid_Hunter, why such a roundabout calculation?
[0:21] <Triffid_Hunter> ShiftPlusOne: seems pretty direct to me.. power * time / volts = amp hours
[0:22] <echelon> is there a way to put the rpi into standby mode?
[0:22] <ShiftPlusOne> well, yeah.
[0:22] <Triffid_Hunter> echelon: no
[0:22] <echelon> and have it wake up for a minute then go back to sleep?
[0:22] <echelon> hrm
[0:22] * lupinedk is now known as Lupinedk
[0:22] <Triffid_Hunter> echelon: perhaps you're trying to do something with the rpi that a microcontroller would be better at?
[0:23] <ShiftPlusOne> Triffid_Hunter, I missed the part where he mentioned 2 weeks, so now your answer makes more sense, heh.
[0:23] <echelon> yeah :/
[0:23] * KiltedPi (~Nbane@host-89-241-139-13.as13285.net) Quit (Remote host closed the connection)
[0:23] * zakora (~NC@tok69-4-82-236-111-173.fbx.proxad.net) Quit ()
[0:23] <Triffid_Hunter> msp430 for example uses the merest trickle of power even when running, and in deep sleep uses less power than a battery's self-discharge rate
[0:23] <echelon> i have an msp430 :)
[0:23] * KiltedPi (~Nbane@host-89-241-139-13.as13285.net) has joined #raspberrypi
[0:23] <echelon> but i need it to use a camera and stuff
[0:23] <Triffid_Hunter> echelon: so if all you're doing is grabbing some sensor data and firing it up a GSM link or something like that, use the msp430
[0:23] <echelon> so linux would have been preferable :/
[0:24] <Triffid_Hunter> camera makes it a bit trickier, stick a solar panel on it
[0:24] <echelon> heh
[0:24] * zleap (~zleap@dsl-217-155-46-222.zen.co.uk) Quit (Quit: Ex-Chat)
[0:24] <echelon> there should be a way to turn off power to the usb right?
[0:25] <Triffid_Hunter> don't think so
[0:25] <Triffid_Hunter> could add it though with a p-fet
[0:26] <Armand> Anyone know a cheap source of surface mount usb ports ?
[0:26] <Armand> I need 60-70.
[0:26] <chithead> some usb hubs have per-port power switching capability
[0:27] * fr0g911 (~jmstick@c-98-199-136-87.hsd1.tx.comcast.net) Quit (Ping timeout: 256 seconds)
[0:27] <chithead> "lsusb -v" will tell
[0:27] <Triffid_Hunter> lsusb -v causes my rpi to kernel panic
[0:27] <chithead> then connect the usb hub to another computer and run lsusb -v from there
[0:28] <Triffid_Hunter> gets to the broadcom hub in the main chip and kaboom
[0:28] * KiltedPi^ (~Nbane@host-89-241-139-13.as13285.net) has joined #raspberrypi
[0:28] <Triffid_Hunter> udevadm info --attribute-walk does the same thing if I point it at a usb device
[0:28] <ShiftPlusOne> Armand, how cheap is cheap? I see you can get 60 on ebay for $25
[0:30] * archistic (~kishor@gateway/tor-sasl/kishor) Quit (Remote host closed the connection)
[0:30] <Armand> I found 10 for ?10. :/
[0:30] * archistic (~kishor@gateway/tor-sasl/kishor) has joined #raspberrypi
[0:31] <ShiftPlusOne> Armand, http://www.ebay.com.au/itm/320790766564
[0:31] * KiltedPi (~Nbane@host-89-241-139-13.as13285.net) Quit (Ping timeout: 256 seconds)
[0:31] <chithead> $0.15/pc http://www.aliexpress.com/item/Connector-USB-Female-USB-A-female-SMD/815118672.html
[0:33] <ShiftPlusOne> 100 order minimum? Still cheaper than the ebay option though
[0:33] <ShiftPlusOne> not by much
[0:33] <ShiftPlusOne> Hmm, if you bump the quantity to 100, the shipping price goes to US $1,100.60
[0:33] <ShiftPlusOne> XD
[0:34] <Armand> Shipping Cost:
[0:34] <ShiftPlusOne> which might be a deal breaker if it's not a mistake
[0:34] <Armand> US $685.14toUnited Kingdom Via Hongkong Post Air Parcel
[0:34] <Armand> O_O
[0:34] <Armand> Well, screw that..
[0:35] <ShiftPlusOne> If you really need cheap, then go through alibaba and try not to get ripped off.
[0:35] <ShiftPlusOne> which may be tricky
[0:35] * tonyhughes (~tonyhughe@ Quit (Quit: Probably closed laptop)
[0:36] * timb_us (~timb_us@pool-72-82-116-111.nrflva.east.verizon.net) Quit (Quit: Linkinus - http://linkinus.com)
[0:36] * Vlad (~vlad@ Quit (Remote host closed the connection)
[0:37] * Vlad (~vlad@ has joined #raspberrypi
[0:39] <Armand> This is already great fun.. I need to generate 700W+ on solar, wire up 10 5v regulators and connect 60 buffered USB ports.
[0:39] <Armand> Loads of batteries. ^_^

[0:43] * zastaph (zastaph@unaffiliated/zastaph) Quit ()
[0:45] <Armand> The ebay option will cost me ?71..
[0:45] * timb_us (~timb_us@pool-72-82-116-111.nrflva.east.verizon.net) has joined #raspberrypi
[0:45] <Armand> Mouser will be ?58
[0:45] <ShiftPlusOne> why 71?
[0:46] <Armand> $108 for 60.
[0:46] <Armand> No.... derp
[0:46] <ShiftPlusOne> ... 5pc
[0:46] <Armand> Sorry.
[0:46] <Armand> -_-
[0:46] <ShiftPlusOne> heh
[0:46] <Armand> I did a double shift last night.. brain-dead. :P
[0:47] <Armand> ?14?
[0:47] <Armand> O_O
[0:47] <ShiftPlusOne> sounds closer
[0:47] <Armand> Damn.. lol
[0:48] <ShiftPlusOne> You were off by a little bit the first time.
[0:48] <Armand> Yeah.. needs more coffee.
[0:48] <Triffid_Hunter> frequently if you're getting a bulk lot you can contact the ebay seller and get an even better price
[0:48] <buzzsaw> writing pi image :-)
[0:48] <ShiftPlusOne> true
[0:49] * rideh (~rideh@unaffiliated/rideh) has joined #raspberrypi
[0:49] <Armand> I might give that a go, Triffid_Hunter.. ;)
[0:49] <ShiftPlusOne> but it's not like the chinese sellers have that much of a profit margin.
[0:49] <Triffid_Hunter> ShiftPlusOne: worst case, they say no
[0:49] <Triffid_Hunter> their profit margin is up to them to decide
[0:50] <ShiftPlusOne> yup
[0:50] * gyeben (~gyonkiben@dsl51B61186.pool.t-online.hu) has left #raspberrypi

[1:03] <Triffid_Hunter> Armand: yikes, expensive!
[1:05] <plugwash> ShiftPlusOne, sure but with many of the cheap ebay deals I bet a lot of what you are paying for is S&H
[1:06] <plugwash> so they can probablly offer a lower price for larger quantities
[1:06] * Geniack (~Geniack@unaffiliated/geniack) has joined #raspberrypi
[1:06] <ShiftPlusOne> yeah, as Triffid says, it doesn't hurt to ask.
[1:07] * MichaelC is now known as MichaelC|Sleep

[1:09] * cpg|away is now known as cpg
[1:10] <Armand> Triffid_Hunter, I'd want 4. :P
[1:12] * linuxstb (~linuxstb@unaffiliated/linuxstb) Quit (Ping timeout: 260 seconds)
[1:15] * cpg is now known as cpg|away
[1:18] <SpeedEvil> Armand: what are you trying to do? how
[1:19] <SpeedEvil> long a time must this thing work - 1,5, or 15 years!
[1:20] * chris_99 (~chris_99@unaffiliated/chris-99/x-3062929) Quit (Quit: Leaving)
[1:20] <Armand> 60 rPi, all on solar. Headless webservers.
[1:20] <Armand> As long as possible.
[1:20] <SpeedEvil> in that case, 700 w is way light
[1:20] <Armand> I was guessing..
[1:21] <SpeedEvil> where are you?
[1:21] <Armand> 720+
[1:21] <Armand> Not in sunny climes.. :/
[1:21] <Armand> London(ish)
[1:21] <SpeedEvil> I'd guess you need more like 6kw, and 30kwh of battery
[1:22] <Armand> Where are you getting 6kw ?
[1:22] * calios (~calios@unaffiliated/calios) Quit (Ping timeout: 252 seconds)
[1:23] <SpeedEvil> you need to size it for the performance in December
[1:23] <SpeedEvil> http://re.jrc.ec.europa.eu/pvgis/apps4/pvest.php
[1:23] <Armand> Which is when it would be the lowest output..
[1:23] <Armand> *derp*
[1:24] <SpeedEvil> London - tick show graphs, calculate
[1:24] <SpeedEvil> the average daily output of 1kw of panels is about 1kw
[1:24] * calios (~calios@unaffiliated/calios) has joined #raspberrypi
[1:24] <SpeedEvil> your charge efficiency into and out of the batteries is perhaps 70% tops
[1:25] <SpeedEvil> you need about 120w*24 =3kWh
[1:25] <Armand> Of course.. I'm being lazy and only thinking optimal conditions. *duh*
[1:25] <SpeedEvil> so, at least 3 kw
[1:25] <SpeedEvil> but, it's not that good.
[1:26] <SpeedEvil> typically, half or more the power might be in a week
[1:26] <SpeedEvil> even with 6kw, if there is a dull week, you're going offline
[1:27] <SpeedEvil> that's before you consider snow on the panels
[1:28] <Armand> Well, I have a plan for that! ^_^
[1:29] <Armand> I'll be using 12v transformers and an automatic switch for backup power.
[1:30] <SpeedEvil> you are just doing this for PR then?
[1:30] <SpeedEvil> the simplest way is to get a small solar panel installation, with feed in tariff, and then offset the price.
[1:30] * wiiguy (~fake@unaffiliated/wiiguy) Quit (Quit: I just broke my connection, but no worries, we can rebuild it. We have the technology.)
[1:31] <SpeedEvil> while grid connected
[1:31] * featheredfrog (~mhofer@cpe-67-250-125-135.hvc.res.rr.com) has joined #raspberrypi
[1:31] <Armand> Nope. I'm hoping the solar will be a constant. I just don't like the idea of losing the whole farm if the batteries go. :/
[1:31] <Armand> Besides, I didn't want to make it simple. :P
[1:33] <SpeedEvil> http://pvoutput.org/aggregate.jsp?p=1&id=4847&sid=3833&t=w&gs=0&v=0&o=date&d=desc
[1:34] <SpeedEvil> look at the outputs for the last four weeks of the year
[1:34] <SpeedEvil> under 0.5kwh/kw
[1:34] <SpeedEvil> meaning you'd need a 12kw panel
[1:35] * int3nz0r (~int3nz0r@ Quit (Quit: Computer has gone to sleep.)
[1:35] <SpeedEvil> or a small generator, running intermittently too
[1:35] * linuxstb (~linuxstb@unaffiliated/linuxstb) has joined #raspberrypi
[1:35] <SpeedEvil> off grid gets murderously expensive
[1:36] * DM9377 (~darin@2002:ae64:b867:0:ca3a:35ff:fecc:e5b5) has joined #raspberrypi
[1:38] <Armand> I'm not too worried about the costs, as the project will have to grow to those maximum figures.
[1:39] <Armand> Sure as hell, I'm not building the whole thing in one hit...
[1:39] <SpeedEvil> you're looking at an investment approaching 10k.
[1:39] <Triffid_Hunter> for green energy you'd probably be better off with a woodgas generator than solar panels in london
[1:39] <Triffid_Hunter> if you bury the ash it's carbon negative
[1:39] <SpeedEvil> maybe 5k, if you add am generator running occasionally
[1:40] * DM9377 (~darin@2002:ae64:b867:0:ca3a:35ff:fecc:e5b5) Quit (Client Quit)

[1:46] <Armand> Not so keen on using generators.. We're going to have 12c diesel generators anyway. :/
[1:46] * chinoto (~chinoto@c-107-2-85-18.hsd1.mn.comcast.net) has joined #raspberrypi
[1:47] <chinoto> Has anyone tried VirtualGL yet? I'm installing libjpegturbo right now from source.
[1:47] * ngc0202 (anonymous@unaffiliated/ngc0202) Quit (Ping timeout: 256 seconds)
[1:48] <SpeedEvil> Armand: do you have grid?
[1:48] <Armand> Mains? Yes, of course.
[1:49] <Armand> I'll be setting this up in a datacenter. :)
[1:51] <Armand> Ohh, it's not for PR, btw.. as you did ask. :P
[1:51] <plugwash> If you are doing a solar setup where you have mains available you'd be mad not to tie it in both to avoid the need for batteries and to benefit from the governments very juicy "feed in tarrifs"
[1:51] <Armand> I'll see..
[1:51] <SpeedEvil> get the panels installed under the feed in tariff, and you need a kilowatt or so or panels
[1:52] <SpeedEvil> is this a centre you own?
[1:52] <Armand> Not personally. O.o
[1:53] <Armand> If it were, I'd say "screw the cost, build it now" :P
[1:53] <featheredfrog> Triffid_Hunter: how is burying wood ash carbon negative? the carbon has burned off as CO2
[1:53] <SpeedEvil> roi on panels bolted to the roof, sized for the peak load, can be fast
[1:53] <[Saint]> Better get some downspout turbines too - I hear they're really efficient ;)
[1:54] <[Saint]> This nice man tried to sell me some out of the back of a van.
[1:54] <SpeedEvil> haha
[1:54] <Armand> I was considing other sources.. as we've got a decent roof-space there.
[1:54] <[Saint]> Oy...
[1:54] <SpeedEvil> as in under 6 years
[1:54] * featheredfrog (~mhofer@cpe-67-250-125-135.hvc.res.rr.com) has left #raspberrypi
[1:54] * [Saint] points out that he was being anything BUT serious.
[1:55] <[Saint]> In most installs, you'd be lucky if they ever paid for themselves in your lifetime.
[1:55] <[Saint]> let alone actually contributed.
[1:56] * Syliss (~Home@adsl-108-198-103-98.dsl.chi2ca.sbcglobal.net) has joined #raspberrypi
[1:56] <[Saint]> Numbers suggesting otherwise are almost certainly lies, or, from people living in the amazon basin ;)
[1:56] <SpeedEvil> I think you mean in the amazon river
[1:56] <[Saint]> heh
[1:57] <Armand> I'm thinking it might end up going to New Jersey, although there is also a hint at Texas. O_O
[1:58] <Armand> California is remotely plausible.. it depends on various concerns. :/
[1:58] <[Saint]> Just...be cautious.
[1:59] <Armand> To avoid blowing anything/anyone up would be great. :P
[1:59] <[Saint]> The people selling you this stuff really don't care if you succeed or not. As mentioned earlier, this is amazingly expensive, and error prone.
[1:59] <Armand> Yeah, of course.
[2:00] <Syliss> im in cali
[2:00] <Armand> There's more than a few brains I can bash together now..
[2:00] <Triffid_Hunter> featheredfrog: trees absorb CO2 from the atmosphere to produce the wood. some is left in the ash. thus, after burning the wood and burying the ash, there is slightly less CO2 in the atmosphere
[2:00] <[Saint]> Sweet! there 'ya go...move to Cali and splice of Syliss' grid.
[2:00] <[Saint]> "free power!" :P
[2:00] <Triffid_Hunter> bah he's gone :/
[2:00] <Syliss> lol
[2:00] <Syliss> i live in a shitty area tho

[2:03] * DDave (~DDave@unaffiliated/ddave) Quit (Ping timeout: 264 seconds)
[2:04] <buzzsaw> is there some sort of a power button for the pi?
[2:05] <[Saint]> no.
[2:05] <[Saint]> that's pi 101
[2:05] <buzzsaw> okay cus i plug it in and have no display :-)
[2:05] <buzzsaw> [Saint]: i just got it like an hour ago :-)
[2:06] <KiltedPi> Is there a website you can go to online- that will rate how dangerous a computer virus is?
[2:06] * DDave (~DDave@unaffiliated/ddave) has joined #raspberrypi
[2:06] <[Saint]> 'shutdown -h now" is your 'power button' buzzsaw
[2:06] <buzzsaw> got it
[2:06] <KiltedPi> sudo
[2:06] <buzzsaw> but first boot and I have no signal displayed on my tv
[2:06] <chinoto> make me a sandwich
[2:06] <KiltedPi> buzzsaw, some peoples tellies can be the reason-
[2:07] <KiltedPi> If you've exhausted everything, have a look on the forums on raspberry pi
[2:07] <[Saint]> buzzsaw: analogue or digital out?
[2:07] <buzzsaw> hdmi
[2:07] <KiltedPi> I've heard this mentioned before, like four or five times now
[2:07] <KiltedPi> When you get the solution, private message me, I'm collecting 'common' bugs
[2:07] <KiltedPi> :)
[2:08] <KiltedPi> They get a completely black screen
[2:08] <KiltedPi> I have heard mention of altering config.txt
[2:08] <[Saint]> lets not overwhelm the guy shall we.
[2:08] <KiltedPi> for raspbian, but thats only going to be neccessary after checking the obvious stuff
[2:08] <KiltedPi> :/
[2:09] <KiltedPi> Yeah, what lights up on your raspberry buzzsaw?
[2:09] <KiltedPi> there are a few wee lights, like.
[2:09] <KiltedPi> ACT (or OK), PWR, FDX etc.
[2:09] <buzzsaw> ONLY the power :-)
[2:09] <KiltedPi> Ah. you won't see anything on screen buzzsaw
[2:10] <KiltedPi> the lack of ACT/OK light, means the SD card is not accessed
[2:10] <KiltedPi> So! Format it- re-install your OS, (Probably raspbian?)
[2:11] <KiltedPi> What are you on, like, with regards to your main computer? Are you using Windows/Windows 7?
[2:11] <buzzsaw> no its kali and I did a dd from my mac
[2:11] <KiltedPi> Kali? Is that an operating system? I'm not familiar
[2:12] <buzzsaw> its a debian child
[2:12] <KiltedPi> kk
[2:12] <KiltedPi> Should be fine then
[2:12] <KiltedPi> What are you imaging with?
[2:12] <buzzsaw> dd
[2:12] <KiltedPi> I'm completely unfamiliar with mac- anyone can take over from me here? :/
[2:13] <buzzsaw> lol dd is a *nix tool :-)
[2:13] <KiltedPi> Until that ACT/OK light lights up though, you will not see anything on screen.
[2:13] <Triffid_Hunter> buzzsaw: the fat16 partition (should be first partition) is intact? has a config.txt?
[2:13] <Triffid_Hunter> buzzsaw: you did dd to the sd card itself, not one of the partitions on it yes?
[2:14] <buzzsaw> I might go grab one of the kali guys but I did this http://docs.kali.org/armel-armhf/install-kali-linux-arm-raspberry-pi
[2:14] <KiltedPi> Yeah, this is where (If you were on Windows) I would say, 'open up disk manager'
[2:14] <KiltedPi> Re-flashing is your first port of call no matter what
[2:14] <KiltedPi> I know that much! :)
[2:15] <KiltedPi> I don't know what the mac equivalent of diskman is...
[2:16] <KiltedPi> Anyway, I'm fixing my friends laptop at the moment, and its got some amount of virii!
[2:16] <KiltedPi> I wondered if theres a website where you can get your virus rated
[2:17] * KiltedPi is starting a virus collection
[2:17] <KiltedPi> this one is called "Retrogamer_4"
[2:17] <KiltedPi> Its neat.
[2:17] * pkrnj (~pkrnj@bas2-montreal47-1279443509.dsl.bell.ca) has joined #raspberrypi
[2:18] <[Saint]> ...and ancient.
[2:18] <KiltedPi> Its pinging the loopback with huge ICMP packets, and then popping up saying "32212 programs are slowing your computer down! Buy our software and-..." etc etc
[2:18] <KiltedPi> I've never seen it before!
[2:18] <KiltedPi> I wish I'd documented them years ago
[2:19] <KiltedPi> Saint, is there anywhere you can view ratings for virii?
[2:20] <[Saint]> Probably, but I tend to at least pretend to stay on-topic here.
[2:20] * Jevermeister (~Jevermeis@unaffiliated/jever) Quit (Quit: /)
[2:20] <KiltedPi> good point.
[2:20] <KiltedPi> I'm just chatting really!
[2:21] <KiltedPi> Well- If anyone knows macs- buzzsaw has a pi related problem
[2:21] * stapper (~quassel@94-226-13-61.access.telenet.be) Quit (Remote host closed the connection)
[2:22] <[Saint]> the problem doesn't relate to mac at all.
[2:22] <[Saint]> s/doesn't/shouldn't/
[2:22] <[Saint]> dd is just a tool, it is essentially the same on any environment.
[2:22] <KiltedPi> I don't know how to format an SD card from a mac, or what dd is @_@
[2:23] <KiltedPi> oh kk.
[2:23] <[Saint]> I gathered.
[2:23] <KiltedPi> I'm new too!
[2:23] <KiltedPi> Socrates said you can only gain knowledge about something when you first admit you know absolutely nothing at all about it.
[2:23] <KiltedPi> :/
[2:24] <buzzsaw> okay figured it out
[2:24] <KiltedPi> re-flashed buzzsaw?
[2:24] <KiltedPi> Or changed config.txt or whatever?
[2:24] * JohannesG (~JohannesG@u193-11-163-53.studentnatet.se) Quit (Quit: ZNC - http://znc.in)

[2:24] * JohannesG (~JohannesG@u193-11-163-53.studentnatet.se) has joined #raspberrypi
[2:25] <buzzsaw> KiltedPi: you need to learn some about dd :-)
[2:25] <buzzsaw> its useful :-)
[2:25] * buzzsaw has not used it in a while
[2:25] <[Saint]> useful - and a NIGHTMARE in the hands of beginners.
[2:25] <[Saint]> ...lets not forget that ;)
[2:26] <buzzsaw> :-)
[2:26] <[Saint]> you're always a typo away from nuking your OS.
[2:26] <buzzsaw> thus the reason you need to know how to use dd ;-)
[2:26] <buzzsaw> that way you can restore...
[2:27] <buzzsaw> dd if=/dev/random of=/dev/sdb :-)
[2:28] <[Saint]> Uhhh...lets not do that.
[2:28] <[Saint]> Someone is bound to think c/p'ing that is a good idea.

[2:29] <buzzsaw> KiltedPi: good one ;-)
[2:30] <buzzsaw> [Saint]: depends...
[2:30] <buzzsaw> we had a guy we were heling for like 3 hours... Ends up the dude was like, "I like to break things and blog how to fix them."
[2:30] <buzzsaw> well if you would have not put crap in your repos to install! it would not break...
[2:32] <buzzsaw> KiltedPi: have you ever run this in linux? ':(){ :|:& };:'
[2:32] <buzzsaw> it teaches you a thing or two...
[2:32] <buzzsaw> so yeah thanks for the quick help :-)
[2:32] <[Saint]> *duuuuude*
[2:32] <ShiftPlusOne> buzzsaw, people have been kicked for that, so... a head up... don't do it.
[2:33] <ShiftPlusOne> *heads
[2:33] <[Saint]> lets not do that here. Please.

[2:33] <[Saint]> So, lets not :)
[2:33] <ShiftPlusOne> Think that will count as a warning then.
[2:33] * buzzsaw -v self
[2:34] <KiltedPi> heh
[2:35] <ShiftPlusOne> ah wait
[2:35] * buzzsaw needs more cdcards...

[2:36] <KiltedPi> I've a few, but my class 10 is my pride and joy here
[2:37] * [Saint] wonders what he is busy waiting for
[2:37] <buzzsaw> haha every one that I had was only a few hundred meg
[2:37] <[Saint]> ...it better be good.

[2:40] <buzzsaw> strip this baby down to the minimums...
[2:41] * cpg|away is now known as cpg
[2:41] <[Saint]> that's one, needlessly time-consuming way to do it...yes.
[2:41] <[Saint]> alternatively, there's the netinstall.
[2:42] <buzzsaw> well... if this does work the way I want it to do I may have to image a few of them all set up exactly the same way :-)
[2:42] <buzzsaw> so immaging will be the faster way
[2:43] <buzzsaw> plus it will be easier to distribute in a nice tarball for others to image for themself
[2:44] <[Saint]> won't licensing bit you in the ass then?
[2:44] <[Saint]> best not to distribute this.
[2:44] <buzzsaw> how so?
[2:44] <[Saint]> lest source claims take up the rest of your days, forever.

[2:54] <[Saint]> If some do, this needs to be clear.
[2:55] <KiltedPi> Although, My friends eight yr old was right next to me as I typed the swear.
[2:55] <KiltedPi> I'm in Scotland, were we use the 'f' word like a comma!
[2:56] <KiltedPi> :D
[2:56] <Twist-> [Saint]: They won't engage in discussion on this topic.. you pretty much just accept that there's going to be petty, random, tyrannical behavior from the ops here, and get on with your life.
[2:56] <KiltedPi> Yeah, thats what I did Twist

[2:57] <[Saint]> Well, yes. I was told upon my first warning that this was "SFW" and I've tried (believe me, its hard for me with my colorful vocabulary..." to abide.
[2:57] <[Saint]> Had I been told it is really supposed to be SF Kindergarten" I'd have acted differently.
[2:57] <KiltedPi> [Saint] I know mate. Its hard, when you just literally forget- I think because the subject matter in here is so adult
[2:57] * [Saint] fudged his commas and brackets
[2:58] <KiltedPi> I think if you aren't apologetic, and swear often, you can expect a ban for sure
[2:58] <KiltedPi> But warnings just 'draw a line in the sand'
[2:58] <[Saint]> Twist-: I don't see it as any of those things, I manage my own channels, with my own rules - what I do think it is, is unclear.
[2:58] <KiltedPi> Anyway. boring topic. Lets talk about LIGHTNING DETECTOR circuits
[2:58] <KiltedPi> Mine arrived in the post
[2:59] <KiltedPi> this week
[2:59] <Triffid_Hunter> KiltedPi: lightning detector? ie am radio?
[2:59] <KiltedPi> I've yet to solder it, and connect to it through I2C
[2:59] <KiltedPi> YEP
[2:59] <Twist-> [Saint]: You're looking for a rational thought process again. There isn't one.
[2:59] <[Saint]> "SFW" doesn't mean much - say - if you're a mechanic.
[2:59] <[Saint]> ...or a council worker. etc.
[2:59] <KiltedPi> It detects the unique radio signal emmiting by lightning strikes
[2:59] <KiltedPi> cost me 30 quid for a breakout (already soldered) Integrated circuit compatible with i2C
[3:00] <KiltedPi> I'll keep you all posted.
[3:00] <KiltedPi> natch.

[3:00] <[Saint]> My lightning detectors are my cats ;)
[3:00] <KiltedPi> heh
[3:00] <KiltedPi> They are unusually attuned to things like weather aren't they.
[3:00] <KiltedPi> My cat recently passed. :(
[3:01] <KiltedPi> Belle the cat. basically got old.
[3:01] <[Saint]> Yeah - they go nuts during electrical storms. Or, prior to, rather.
[3:01] * Turingi (~devon@unaffiliated/devon-hillard/x-7250961) Quit (Quit: Leaving)
[3:01] <Twist-> How does that work? You come home to a small pile of stir fry in the driveway, and conclude that lightning occurred?
[3:01] <[Saint]> Mine do at least.
[3:01] <KiltedPi> She used to run around before them. yep
[3:01] <[Saint]> Twist-: that would be /one/ way ;)
[3:01] <KiltedPi> heh! nope! A particularily 'weird' frequency of radio signal is emmited when ever lightning zstrikes
[3:01] <KiltedPi> This circuit detects the pattern
[3:02] <KiltedPi> And it outputs it in an i2C friendly way, so I can read it on the pi
[3:02] <[Saint]> what kind of distance are we talking here?
[3:02] <KiltedPi> I thought it would be a neat distraction
[3:02] <KiltedPi> 300 kilometres!
[3:02] <[Saint]> wow...
[3:02] <KiltedPi> I think, not sure- that seems alot actually
[3:02] <KiltedPi> one sec- datasheet
[3:03] <KiltedPi> loading: http://www1.futureelectronics.com/doc/AUSTRIAMICROSYSTEMS/AS3935.pdf
[3:03] <KiltedPi> 1 kilometre in fact!
[3:03] <KiltedPi> I misread it-

[3:06] <[Saint]> I suppose now you'll be aware of the ones you slept through, or failed to notice the large artificial sun outside your window ;)
[3:07] * [Saint] admits he thought 300K was quite a bit more impressive
[3:07] <Triffid_Hunter> can pick them up at 300k with an am radio so I'm failing to see why this chip is interesting
[3:07] <KiltedPi> hah!
[3:08] <KiltedPi> oh
[3:08] <KiltedPi> the radio signals you are getting might not be lightning tho
[3:09] <KiltedPi> You need to differentiate them
[3:09] <KiltedPi> a wee bit of software basically
[3:09] <KiltedPi> theres a specific pattern
[3:09] <KiltedPi> You basically leave it running, and it eliminates background traffic/noise
[3:09] <Triffid_Hunter> tune into a dead band, whenever we see a massive spike it's probably lightning :) can process it if you want to be more selective
[3:10] <KiltedPi> Might not be lightning tho eh?
[3:10] <KiltedPi> I suppose that is what it does as well
[3:10] <KiltedPi> it has a slightly more sophisticated tuner tho
[3:10] * [Saint] makes plans to move near KiltedPi and set up a broadcast station that broadcasts nothing but the signal emitted during a lightning strike
[3:10] <[Saint]> ...for, science!
[3:10] <KiltedPi> designed specifically for lightning
[3:10] <KiltedPi> haha
[3:10] * grantsmith (~grantsmit@unaffiliated/grantsmith) has joined #raspberrypi
[3:11] <KiltedPi> You can generate the signal yep
[3:11] <KiltedPi> It just detects the pattern, and discerns if it fits the profile
[3:11] <KiltedPi> It's EMP we're talking here tho.
[3:11] <KiltedPi> EMF*
[3:12] * IT_Sean recommends [Saint] make that a mobile broadcast station, to keep KiltedPi on his toes
[3:12] <KiltedPi> not a very exact science

[6:35] <buzzsaw> sqlite should run fine on a pi?
[6:36] <chinoto> buzzsaw: your distro might already be using it for something :P
[6:36] <buzzsaw> my distro?
[6:36] <SwK> buzzsaw: i run freeswitch on pi and that depends heavily on sqlite
[6:37] <buzzsaw> multiple things should be able to run sqlite
[6:37] <chinoto> someone was talking about AMP working, so something that's supposed to be light should definitely work
[6:37] <[Saint]> I don't think you're quite getting to grips with the serious IO penalty from the sdcard
[6:38] <[Saint]> even the fastest sdcard is going to be slower than an average spinning platter.
[6:38] <buzzsaw> switch the database to a usbstick then
[6:38] <SwK> io penalty or not, it still works??? you just might kill your sd card if you are doing to many tuple changes lol
[6:38] * [Saint] didn't say it didn't work
[6:38] <seba-> f8l, i think it works now
[6:38] <chinoto> or get a usb to sata adapter
[6:38] <chinoto> and use a harddrive or ssd
[6:38] <buzzsaw> but if you need to run something with preformance why use a pi :-)
[6:39] <[Saint]> also, I wouldn't expect you'd kill a sdcard. I call shenanigans on those who claim to have done so.
[6:39] <SwK> i was thinking of pulling unaclockeres thing and putting a msata on a usb adapter
[6:39] <[Saint]> you should be able to write back and forth from it for most of your lifetime.
[6:39] <SwK> [Saint]: I have killed flash media
[6:39] * buzzsaw killed a sdcard onceupon a time...
[6:39] <chinoto> it's odd that I'm amazed minecraft is working on the pi
[6:39] <SwK> i've killed everything from CF cards to SD cards
[6:39] <[Saint]> SwK: there's always outliers.
[6:39] <SwK> (even killed an SSD recently)
[6:39] <[Saint]> manufacturing defect one presumes.
[6:40] <[Saint]> SSDs are nowhere near "reliable" yet.
[6:40] <[Saint]> Not even close.
[6:40] <buzzsaw> using a usbstick as swap *badIdea*
[6:40] <chinoto> maybe it's just because of how long it took me to get around to compiling virtualgl and finding it CAN'T work because it uses GLX
[6:40] <SwK> nope just killed them on write cycles
[6:40] <SwK> (i tend to do that tho lol)
[6:40] <Triffid_Hunter> buzzsaw: tell microsoft that
[6:40] <seba-> i have a killed SD card
[6:41] <buzzsaw> yeah I dont use microsoft much...
[6:41] <chinoto> it's nice having dd-wrt, I have a free ethernet port now :)
[6:42] <Triffid_Hunter> my omxplayer is broken currently :/
[6:42] <buzzsaw> ddwrt eww...
[6:42] <seba-> f8l, or not hm lol
[6:42] <buzzsaw> they started doing what they complained about their predocessor doing...
[6:42] <seba-> f8l, always when i tell you it works, it dies
[6:42] <seba-> you have some voodoo
[6:43] <buzzsaw> go for openwrt :-)
[6:43] <Triffid_Hunter> is there a command to update gcc symlinks? I seem to have both 4.6 and 4.7 installed with relevant symlinks pointing to 4.6
[6:44] <seba-> hm
[6:44] <seba-> this is weird
[6:45] <seba-> is it possible that a bad PSU
[6:45] <SwK> openwrt gives me headaches
[6:45] <seba-> would be killing SD cards?
[6:45] <buzzsaw> it could...

[6:46] <[Saint]> Are you using quality media?
[6:46] <seba-> [Saint], the raspberry pi worked for like 1 month and then i was getting corruption
[6:46] <[Saint]> People seem to forget this makes a big difference.
[6:47] <[Saint]> ie. don;t go buying the cheapest card you can.
[6:47] <seba-> [Saint], i've bought a sony card now
[6:47] <seba-> it happened after few days
[6:47] <seba-> i think there's something wrong with the raspberry pi
[6:47] <[Saint]> Well, there's your problem - Sony ;P
[6:47] <seba-> or PSU
[6:48] <seba-> [Saint], well i've had silicon power before that
[6:48] <seba-> i don't think the problem is in the SD cards
[6:48] * screwloose (~doc@64-121-21-56.c3-0.tlg-ubr3.atw-tlg.pa.cable.rcn.com) has joined #raspberrypi
[6:49] <[Saint]> Silicon Power isn't exactly known for quality either...
[6:49] <Triffid_Hunter> sandisk are good last time I checked
[6:49] <[Saint]> They can be.
[6:50] <seba-> ok but don't you find it a bit strange
[6:51] <[Saint]> No. No one here has enough information to find anything out of place.
[6:51] * jankyhellface (~jankyhell@ has joined #raspberrypi
[6:51] <Triffid_Hunter> seba-: SD cards need a rock solid 3.3v supply to work properly.. rpi is already very sensitive to power quality
[6:51] <seba-> Triffid_Hunter, yes, that's why i suspect the PSU, it's a cell phone charger 1A 5V
[6:51] <Triffid_Hunter> I have a 5v 2.5A tablet charger connected directly to the GPIO header, never had a single problem with power
[6:53] <[Saint]> why is it connected directly to the header? o_0
[6:54] <Triffid_Hunter> [Saint]: because I simply don't trust the miniscule pins in the usb-c connector to carry enough power to make the pi reliable.. at least with 0.1" headers I know I can put a couple of amps through and it'll be fine
[6:54] <seba-> hm
[6:54] <seba-> is there a debug mode
[6:54] <seba-> i don't have a monitor
[6:55] <[Saint]> Triffid_Hunter: those traces are perfectly capable of carrying that current.
[6:55] <[Saint]> there's no need for such paranoia.
[6:56] <[Saint]> the GPIO goes to *exactly* the same size trace in the board itself...if anything was going to fail, it would eb the board traces, not the pins in <insert socket here>
[6:56] <[Saint]> tl;dr: no need - its fine.
[6:57] <Triffid_Hunter> [Saint]: not worried about the traces.. it's the contact in the socket that bugs me. I can see how tiny the contact area is, seems like a recipe for hot-spotting to me
[6:57] <[Saint]> Nah.
[6:57] <Triffid_Hunter> also I'm an EE, got many years of experience to back up my dislike for powering things via tiny usb connectors. it's different for usb-A, those are bigger, and it's different for phones and tablets because they have a UPS built in so doesn't matter if the power is flakey sometimes
[6:57] <seba-> what could cause corrupion
[6:58] <seba-> besides bad SD card
[6:58] <[Saint]> think of the abuse your (almost certainly charged over micro-USB) phone gets - and how it behaves.
[6:58] <Triffid_Hunter> seba-: momentary imperfect contact in the usb connector caused by vibration or movement
[6:58] <[Saint]> years and years and years of abuse.
[6:58] <seba-> Triffid_Hunter, you mean like bad power
[6:58] <[Saint]> then compare that to how carefully one treats the pi.
[6:58] <seba-> that would damage the SD card?
[6:58] <Triffid_Hunter> seba-: sub-standard or noisy power supply would do it too
[6:59] <seba-> hm
[6:59] <seba-> this is shitty
[6:59] <Triffid_Hunter> seba-: damage? unlikely. but if the power is flakey while it's writing you can guarantee to get corrupted data written into the flash
[6:59] <[Saint]> easy test - grab a multimeter
[6:59] <seba-> well the previous SD card was damaged
[7:00] <[Saint]> what the!?! ...I get kicked for a three letter a word that also refers to a donkey - and that happens...nothing.
[7:00] <[Saint]> lol
[7:00] <[Saint]> lol, and lol hard, dost I.

[7:38] <seba-> a lot of people are having problems
[7:38] <seba-> with the SD corruption
[7:38] <[Saint]> seba-: note the difference between that post and your claims?
[7:38] <seba-> [Saint], which is?
[7:39] <[Saint]> you calimed *damage* to the card itself.
[7:39] <[Saint]> *claimed
[7:39] <[Saint]> filesystem corruption - entirely different.
[7:39] <seba-> [Saint], yes, well the previous had damage, i haven't checked this one yet
[7:39] <[Saint]> and totally recoverable.
[7:39] <seba-> [Saint], yeah by reformating
[7:39] <seba-> that sucks
[7:40] <[Saint]> its removable storage - having any data there you care about not backed up is your fault.
[7:40] <seba-> [Saint], no, it sux that i have to reformat frequently
[7:41] <[Saint]> it takes like 30 seconds to do.
[7:41] <seba-> yeah but i have to set up everytime the settings, i'll probably make an image now of the settings
[7:41] <seba-> but still it's idiotic that i have to do this
[7:41] <seba-> something is causing this sorts of crap
[7:41] <seba-> hm
[7:41] <[Saint]> Errr...why would you need to do that?
[7:42] <[Saint]> create an image of a good installation, regularly.
[7:42] <[Saint]> dd it back when you have tyrouble.
[7:42] <[Saint]> you don;t need to set up from a clean install every time.
[7:42] <seba-> yes but i don't like that it causes corruption
[7:42] <seba-> especially so frequently
[7:42] <lyndsysimon> seba-: respectfully, you're working with a $35 computer that's the size of most mice from 15 years ago. We live in amazing times - gotta keep it in perspective :)
[7:42] <seba-> lyndsysimon, so?
[7:43] <seba-> my cell phone doesn't cause so much corruption
[7:43] <seba-> it has also ARM inside
[7:43] <lyndsysimon> seba-: So, if you find a problem, fix it.
[7:43] <seba-> that's what i'm trying to do
[7:43] <seba-> duh
[7:43] <seba-> i'm asking if maybe anyone has a good idea
[7:43] <seba-> on how to fix it
[7:43] <seba-> instead of telling me that it's cheap
[7:43] <Triffid_Hunter> seba-: get a 2A supply. connect it to the GPIO port. if you still have SD card corruption, come tell us. if that fixes it, also come tell us :)
[7:43] <lyndsysimon> I didn't say it was cheap, I would point out that it's amazing.
[7:43] <[Saint]> All I see is a very small percentage of people, making claims almost always without any actual eveidence.
[7:43] <seba-> Triffid_Hunter, yes, i'm thinking of that

[7:44] <seba-> [Saint], what sorts of evidence do you want
[7:44] <seba-> i don't get it
[7:44] <[Saint]> What I am saying is, there's absolutley no reason to believe that this isn;t user error.
[7:44] <[Saint]> And many reasons to believe it is.
[7:45] <seba-> [Saint], well tell what kind of user error i've made, like give possibilities
[7:45] <Triffid_Hunter> seba-: http://triffid-hunter.no-ip.info/101_0059.JPG
[7:46] <[Saint]> improper shutdown, poorly seated card, use of a power supply that cannot provide the desired range...
[7:46] <Triffid_Hunter> seba-: if you do that, please be very careful when plugging in the supply.. one wrong pin and your rpi is fried permanently
[7:46] <seba-> Triffid_Hunter, yes i'm aware of that
[7:46] * [Saint] advises not doing that
[7:46] <seba-> why
[7:46] <[Saint]> There's really no reason to.
[7:46] <[Saint]> Like, at all.
[7:47] <seba-> [Saint], no improper shutdown, i haven't touched it but it could be, but the socket is already a piece of crap, flimsy
[7:47] <Triffid_Hunter> try it anyway, there are several reports of it making a significant difference
[7:47] <seba-> [Saint], a power supply can be the reason, but it's weird that it would be
[7:47] <seba-> Triffid_Hunter, yes i will
[7:47] <seba-> Triffid_Hunter, i'll use a computer PSU
[7:47] <lyndsysimon> FWIW, with my limited experience, I agree. I've not seen anything in the official docs saying it's OK to power the device through the GPIO.
[7:47] <Triffid_Hunter> seba-: rpi is extremely sensitive to power supply quality compared to other equipment.. probably not enough capacitors onboard
[7:48] <chinoto> I need to see my neighbor tomorrow... must obtain legos O_O
[7:48] <seba-> Triffid_Hunter, yeah
[7:48] <seba-> almost none
[7:48] <[Saint]> Why is it weird that failure to supply a device with its power requirements would cause undesireable results?
[7:48] <seba-> [Saint], it's not weird
[7:48] <[Saint]> I don't think it is weird at all.
[7:48] <Triffid_Hunter> [Saint]: lots of folk with 1A supplies when rpi is rated 700mA max have supply trouble
[7:48] <seba-> yes
[7:48] <[Saint]> seba-: it is or it isn't - which.
[7:49] <[Saint]> you said it is, now you're saying it isn;t.
[7:49] <seba-> [Saint], look RPI is made for kids apparently
[7:49] <Triffid_Hunter> 1A > 0.7A thus requirements are theoretically satisfied, however rpi still won't work properly
[7:49] <seba-> and it should work
[7:49] <[Saint]> make up your mind please :)
[7:49] <lyndsysimon> I'm actually powering mine at the moment from the USB port on my Macbook. That's what, 500mA?
[7:49] <[Saint]> seba-: no - it is made for education.
[7:49] <[Saint]> education != kids
[7:50] <seba-> [Saint], well whatever point is that it doesn't work properly when expected to
[7:50] <[Saint]> Mine does.
[7:50] <lyndsysimon> [Saint]: Yep. I'm 29 years old, and using mine to learn the basics of electrical engineering.
[7:50] <chinoto> kids are primary target of edumacation, the wires in adults have solidified and they are forever stoopid
[7:50] <seba-> [Saint], what kind of power supply do you have
[7:50] <[Saint]> A cheap Samsung 2A wall-wart.
[7:50] <seba-> [Saint], see, that's the point
[7:50] <seba-> i have a 1A and it doesn't
[7:51] <seba-> actually it worked
[7:51] <seba-> but now it doesn't
[7:51] <seba-> it might be the PSU but i don't know
[7:51] <[Saint]> You haven't actually verified your PSU is supplying the stated voltage.
[7:51] <[Saint]> that would be one of the first things to check.
[7:51] * [Saint] actually mentioned this a lot earlier
[7:51] <lyndsysimon> I got my RPi at PyCon. They supplied a power adapter too - it's a 5V/1A
[7:51] <seba-> [Saint], i did, after the polyfuse it's slightly bellow the optimum, but it's reported to work without problems at such voltage
[7:52] <[Saint]> what is "slightly below the optimum" and what else are you attempting to power with it?
[7:53] <seba-> [Saint], i haven't tried anythign else, because it worked
[7:53] <[Saint]> So - no keyboard, no mouse - no wireless dongle - nothing?
[7:53] <Triffid_Hunter> powering via gpio bypasses the polyfuse I suppose
[7:53] <seba-> [Saint], nothing, just ethernet
[7:53] <seba-> Triffid_Hunter, yes
[7:54] <seba-> i'm installing linux on a second computer
[7:55] <[Saint]> Well - if you're that convinced its not your problem - go through the returns/claims process.
[7:55] <seba-> i'll try to check what's on the SD card
[7:55] <seba-> if there are any logs
[7:55] <seba-> [Saint], i'm not, i just don't know what's wrong

[8:11] <seba-> Triffid_Hunter, yes, so it could be that the power dips or something, but then 0.7A minimum is a lie or it should be a very good 0.7A charger not just a phone charger
[8:12] <[Saint]> For a model B, even if you're not powering anything else - as the docs state - you really want 1A

[9:00] <gordonDrogon> or rather until I stopped using the new 'turbo' dynamic OC mode - with the old fixed OC it was OK.
[9:00] <gordonDrogon> it's mostly the card type and the power supply.

[9:01] <seba-> gordonDrogon, well i have to buy a new SD card, i think this is not good anymore
[9:01] <seba-> :/
[9:01] <[Saint]> huh - what? Isn't a PC following spec only going to give it 500mA?
[9:01] <seba-> [Saint], no computer is following specs
[9:01] <seba-> excet a few dells
[9:01] <Triffid_Hunter> http://triffid-hunter.no-ip.info/101_0061.JPG <-- stops right here.. I take the cmdline and config options out and put back the fixed split and it's fine
[9:02] <gordonDrogon> 500mA will be enough to boot a Pi with no peripherals, however I've yet to see a PC that obeys the spec...
[9:02] <Triffid_Hunter> [Saint]: 5Vsb perhaps.. the main 5v rail is generally rated >15A
[9:02] <gordonDrogon> I power my Pi's regularly from my PC and Laptops.
[9:02] <Triffid_Hunter> unless you go via the usb port of course..
[9:03] * [Saint] wonders what laptops are these
[9:03] <seba-> could a bad PSU damage the SD card?
[9:03] <gordonDrogon> it costs more for the PC/Mobo makers to put in the correct chips with current sensing/negotiation, etc. so a lot don't.
[9:03] <[Saint]> It shouldn't be giving any more than 500mA unless the device explicitly tells it to.
[9:03] <seba-> i get bad verifies
[9:03] <seba-> read+write is ok, just bad verify
[9:03] <gordonDrogon> seba-, it's unlikely hte card is damaged - you can test for that in a different PC. More likely some data corruption happens to/from the card in the Pi.
[9:04] <seba-> gordonDrogon, i'm checking in a PC now, i'll try in an another

[9:28] <[Saint]> na85: query something along the lines of "debian+reset root password"
[9:29] <[Saint]> or, figure out where you're going wrong with dd
[9:29] <Triffid_Hunter> na85: mount sd card on your host, then edit /etc/shadow and dump in the relevant hash from your host
[9:30] <Triffid_Hunter> na85: or simply edit /etc/inittab on the rpi's sd card and make it so it doesn't ask for a pass
[9:30] <na85> awesome, thanks Triffid_Hunter

[9:37] <[Saint]> ...what distro is this?
[9:38] <na85> raspbian
[9:38] <[Saint]> it definitely should exist...
[9:38] * na85 shrugs
[9:38] <na85> oh
[9:38] <Gadgetoid> gordonDrogon: Strikes me it might be easier to leave it all on the board and solder some wires to tap into the A/C, which I can then switch with transistors to my hearts desire
[9:38] <gordonDrogon> Gadgetoid, so the HT goes into a circuit with a row of transistors to switch the EL wires on/off?
[9:38] <na85> i bet this is the raspbian fork that has X removed
[9:38] * na85 grumbles
[9:38] * na85 had two images
[9:39] <gordonDrogon> Gadgetoid, ah, they'll be triacs.
[9:39] <Gadgetoid> gordonDrogon: The LED level driver looks like it switches 3 confusingly placed tiny little surface mount transistors
[9:40] <Gadgetoid> It's the KA2284, and it's almost certainly not operating from 100V A/C so that gives me a point to tap in
[9:40] <gordonDrogon> Gadgetoid, so hook into those 3 triacs, or the led level driver before them.
[9:40] <Gadgetoid> This PCB looks like it was made by monkeys, too, it's shoddy as all hell
[9:41] <gordonDrogon> Gadgetoid, that'll be driving the gates of the triacs directly.
[9:41] <gordonDrogon> if the KA2284 is through hole, you should be able to unsolder it easilly and solder in your 3 wires.
[9:42] <Gadgetoid> Found where to tap in, thee's a little resistor before each transistor, just need to find the supply voltage going into the KA2284??? I'd take the input voltage at a pinch, but bad things might happen
[9:42] <gordonDrogon> you just need to trigger the triacs - sticking 3.3v into them might do it...
[9:43] <Gadgetoid> drat, I'm covered in conductive paint again??? that stuff gets around! brb
[9:43] * Caribou| (~Caribou@ has joined #raspberrypi
[9:43] <Gadgetoid> gordonDrogon: thanks for your help! going to give it a tentative prod
[9:44] <Gadgetoid> I wonder if I've got any transistors in my bits box that will switch 100v ac
[9:44] <gordonDrogon> Gadgetoid, AC remember - you want triacs.
[9:45] <Gadgetoid> Oooh!
[9:46] <Gadgetoid> Good point, didn't grok there was a difference
[9:47] <gordonDrogon> wonder if they work with DC. much easier to switch.
[9:47] <Gadgetoid> Success!
[9:48] <Gadgetoid> Got a tiny spark, too!
[9:48] * cpg is now known as cpg|away
[9:48] <gordonDrogon> er.. I'm sure you don't want sparks..
[9:48] <Gadgetoid> response curve is awful, I wonder if that's the EL wire
[9:48] <seba-> gordonDrogon, read only test shows no errors, but read+write+verify shows
[9:49] <Gadgetoid> gordonDrogon: I took the input voltage directly, it didn't like that, but there's a little resistor, presumably a voltage divider setup, after which it works beautifully
[9:49] * Mikelevel (~MoVeWoRk@60.Red-80-25-210.staticIP.rima-tde.net) has joined #raspberrypi
[9:49] <gordonDrogon> Gadgetoid, you're connecting 3.3v to the base of the triac?
[9:49] <gordonDrogon> seba-, maybe the card is bad then...
[9:50] <Gadgetoid> gordonDrogon: More or less, yes, although I'm not sure it's 3.3v
[9:50] <Gadgetoid> Input voltage is 6v
[9:50] <seba-> gordonDrogon, but is it possible that RPi made the damage, 3 days ago it was new and it wasn't damaged, checked
[9:50] <gordonDrogon> take a 3.3v supply from the Pi and give it a go...
[9:51] <gordonDrogon> seba-, I've no idea. I think it's unlikely, but I really don't know.
[9:51] <seba-> oh ok
[9:51] <gordonDrogon> seba-, I think if there were cases of the Pi damaging SD cards (rather than just causing corruption which is cured with a reformat) then there would be posting about it by now ...
[9:52] <Gadgetoid> Found the pin on the driver, will just solder onto the underside and leave it in place
[9:52] <seba-> gordonDrogon, ok, but i doubt people check read+write+verify, but this is the second card it happened
[9:52] <[Saint]> Heh - I already tried that...mind you, at that point OP was adamant that this was the second card that had been caused physical damage, ...without verification ;)
[9:53] <seba-> [Saint], well how should i verify it, reccomend a protocol
[9:53] <[Saint]> you need a control for one. which you don't have currently.
[9:54] <seba-> [Saint], what would be a control in this case?
[9:54] <[Saint]> you need a known good state, and then to prove that a known bad state can be caused with nothing but normal use.
[9:54] <na85> i.e. you need a known-to-be-working card
[9:54] <Gadgetoid> Drat, it's gonna have to come off, every channel is lighting
[9:54] <seba-> but it was a good card
[9:54] <seba-> 3 days ago
[9:54] <seba-> i've checked it
[9:55] * owen_ (~owen@ Quit (Quit: Konversation terminated!)
[9:55] <[Saint]> the known good state would be a card that has never touched the pi - or anything - for that matter - and checks to verify this known good state.
[9:55] <seba-> yes
[9:55] <seba-> that's what i did
[9:55] <[Saint]> simple saying "it worked X days ago" is meaningless.
[9:55] <[Saint]> and prone to bias.
[9:55] <seba-> [Saint], it never touched the pi
[9:55] <na85> updating firmware

[9:55] * na85 pumps fists
[9:55] <seba-> it was ok
[9:56] * [Saint] gives up
[9:56] <[Saint]> you just keep believeing the problem without proof and we'll call it a day.
[9:56] <seba-> [Saint], what kind of proof
[9:56] <[Saint]> sound good? yep. great.
[9:56] <seba-> should i try it with 1000 SD cards

[9:58] <seba-> look

[9:59] <na85> ^
[9:59] <[Saint]> with proof.
[9:59] <seba-> gordonDrogon, i'm not sure, how can i be sure?
[9:59] <seba-> yes what kind of proof
[9:59] <seba-> please give me a step by step protocol
[9:59] <seba-> to what constitutes a proof
[9:59] <gordonDrogon> no.
[9:59] <gordonDrogon> you're the one stating it's causing damage. you work out the protocol.
[10:00] <[Saint]> you could try reading what I wrote. start with a card that is in a known good state, verify this state, <passage of time>, verify that the pi caused a known bad state; verify this state.
[10:00] <na85> i would say you'd need 2 identical SD cards, flashed w the same image, use one in the pi until it breaks, then run a diff against the two images
[10:00] <[Saint]> I've written this at least three different ways already.
[10:00] <gordonDrogon> I'm saying its highly unlikely, but I won't rule out the possibility, however as I never see it myself and I don't see reports of others seeing it either, I'm not really in a position to test some theory. (and I don't want to either)
[10:00] <seba-> [Saint], yes, i did that, the only difference was that i didn't use it for sometime without the PI
[10:00] <seba-> i only tested it
[10:01] <[Saint]> No, you didn't. You never verified the card was known good.
[10:01] <seba-> [Saint], yes i did
[10:01] <seba-> wtf
[10:01] <[Saint]> you've simply said "it worked".
[10:01] <[Saint]> which is meaningless.
[10:01] <seba-> [Saint], no
[10:01] <seba-> wtf
[10:01] <[Saint]> you lie. numbers don't.
[10:01] <seba-> WTF
[10:01] <seba-> you're crazy
[10:01] <seba-> i've said a ton of times
[10:01] <seba-> that i did a read+write+verify test
[10:01] <seba-> before putting in a pi for the first time
[10:01] <seba-> and it passed without errors
[10:01] <[Saint]> so - the very first thing you did, before using this card, ever, was run a full set of checks on it?
[10:02] <seba-> yes
[10:02] <[Saint]> please do tell me where you said that happened.
[10:02] <[Saint]> You're trolling mate.

[10:09] <gordonDrogon> you can measure capacitance on a Pi directly though - it might make an intersting project.

[11:43] <cellardoor> Hi Raspberry Pi experts! I've got a 500GB USB portable hard drive I want to use as "big storage" for my Pi. Whenever I plug it in though, the Pi restarts itself and even then doesn't detect the HDD when I run sudo fdisk -l. Tried with a 4GB Memory stick and that works just fine, any idea on what's going on?
[11:43] <Jerub> cellardoor: is the external harddrive independently powered?
[11:44] <Triffid_Hunter> cellardoor: need a powered hub
[11:44] <snowrichard> i would suspect that the hard drive draws too much power for the usb port to supply. Try running it off a powered usb hub
[11:44] <Triffid_Hunter> cellardoor: rpi is very sensitive to power, and even more sensitive to usb devices sucking heaps of power
[11:45] <cellardoor> Jerub: Oh what :( But I've got a power supply shoving in 1.5A tops to the Pi, and the most a USB port can take is 500mA? :( damn. Ah well guess I will just use it elsewhere, thanks :)
[11:45] <Triffid_Hunter> cellardoor: yeah but it has to go through the pi.. pi doesn't like that
[11:45] <Triffid_Hunter> need to bypass the pi
[11:45] <snowrichard> have you got a linux box on your network? you could use NFS mount for extra data space
[11:46] <Jerub> cellardoor: lots of usb harddrives come with independent power, or a cable that has 2 usb connectors, one for power one for data.

[11:46] <cellardoor> snowrichard: well sure many, but the whole idea was to make the Pi a low-power-consumption server :(
[11:46] <cellardoor> Jerub: guess I will have to look into that then :)
[11:47] <cellardoor> I have a powered Hub somewhere but it's ancient and possibly even USB 1.0 - will look into it
[11:48] <ShadowJK> cellardoor; usb harddrives without power adapters consume somewhere around 600-900mA, more when they spin up. rPi input power limit is at around 1.1A iirc, and it uses 700 ish itself, leaving 400 available
[11:48] <[Saint]> there *is* no upper limit on input I thought.
[11:48] <[Saint]> though, it doesn't stop people claiming so.
[11:49] <cellardoor> ShadowJK: What was interesting is that the Pi would boot up fine with the drive already plugged in. The drive wouldn't work properly and the light would constantly flicker. Guessing that the Pi was just refusing to give the drive enough power or something? Or perhaps the Pi was just clinging to life itself

[11:52] <[Saint]> many have, yes.
[11:53] <Triffid_Hunter> [Saint]: you can use a supply with whatever current rating you like that's >1A, doesn't mean the pi is gonna let more than about 1A through.. the usb connectors can't handle it for a start :P
[11:53] <[Saint]> Triffid_Hunter: ...exactly, but, that's not the point.
[11:53] <[Saint]> many claim there's some mystical upper limit for PSUs - there isn't.
[11:53] * snowrichard (~Richard@ Quit (Quit: Leaving)
[11:55] <[Saint]> Jerub: as long as it can supply a 5V at ~1A stable - it doesn't matter where it comes from really.
[11:56] <Triffid_Hunter> rpi will still brown out if you pull 500mA from the usb port even if your supply can push 20A
[11:56] <Triffid_Hunter> that's where the power budget comes from
[11:57] <[Saint]> there's a lower limit - yes.
[11:57] <[Saint]> no upper, though.

[11:57] <[Saint]> ...was I in some way unclear?
[11:58] <Triffid_Hunter> [Saint]: you're confusing power budget of the pi itself with power supply ability
[11:58] <gordonDrogon> the crux of the Pi is the 700mA polyfuse on the 5v input though.
[11:58] * violet-rpi (~quassel@laptoptina.broker.freenet6.net) Quit (Ping timeout: 264 seconds)
[11:58] <gordonDrogon> Pi needs 3-400 mA - leaving 3-400mA for USB, etc.
[11:59] <gordonDrogon> so a good beefy PSU is probably more suited to powering a powered hub - which can then feed the Pi and USB peripherals.
[11:59] <[Saint]> Triffid_Hunter: how exactly does one intend on pulling 500mA from a raspi?
[11:59] * bertrik (~quassel@rockbox/developer/bertrik) Quit (Remote host closed the connection)
[11:59] <[Saint]> even using both ports on a Model B you couldn't manage that :)
[11:59] <Triffid_Hunter> [Saint]: cellardoor is plugging a usb disk drive into it...
[12:00] <[Saint]> Triffid_Hunter: great - but - there's a huge flaw there.
[12:00] <[Saint]> it only supplies 140mA
[12:00] <gordonDrogon> from my own observations, something that "jars" the voltage on the USB will reboot the Pi - so somethings can be plugged at when it's off and powered up, but plug them in while the Pi is running and the Pi will reboot.
[12:01] <Triffid_Hunter> I have some 10u ceramic caps, sounds like I should add a few
[12:01] <gordonDrogon> some people have.
[12:01] <gordonDrogon> put them right under the USB sockets on the Pi.
[12:01] <Triffid_Hunter> I'd be more inclined to hang them on the 3v3 regulator actually
[12:02] <Triffid_Hunter> don't give a crap if the usb power dips, it's the power for the core that I want to keep stable
[12:02] <gordonDrogon> experiment & see what's best :)
[12:02] <gordonDrogon> core power comes from the 5v supply - if that dips then the 3.3v will drop out.
[12:02] <Triffid_Hunter> yeah hence putting the caps on the 3v3 reg
[12:03] <gordonDrogon> personally I'd put them as close to the device that causes the dip - ie. the usb sockets, however - experiment and see.
[12:04] <Triffid_Hunter> don't want sparks in the usb socket if I can help it
[12:05] <gordonDrogon> maybe higher power usb devices could be better designed... but that would cost money...
[12:05] <cellardoor> gordonDrogon: I saw the voltage thing. Hard drive killed it dead. But could boot up with it plugged in
[12:06] <[Saint]> cellardoor: that's really quite phenomenal
[12:06] <[Saint]> ...that shouldn;t work at all.
[12:06] * DenBeiren (~Denbeiren@ Quit (Ping timeout: 245 seconds)
[12:06] <Triffid_Hunter> [Saint]: why not?
[12:07] <[Saint]> the pi will only supply 140mA via USB, as I said earlier.
[12:07] <gordonDrogon> that's my observation of plugging in high power usb devices - plug them in with the Pi running and it'll reboot the Pi (or just crash it), but plug them in with the Pi off and they're OK.
[12:07] <Triffid_Hunter> [Saint]: that's the model A.. latest one ditched the output polyfuse altogether, has a bigger one at the input
[12:08] <Triffid_Hunter> [Saint]: also, polyfuses are not exactly precise in terms of trip current
[12:08] <gordonDrogon> The 4D displays I've used are like that. I halt the Pi, then plug the display in - which cause them to re-boot without me touching them...
[12:08] <steve_rox> sudden power drop it dont like
[12:08] <gordonDrogon> it's the Rev 1 boards with the USB polyfuses - the 1.1 and the Rev 2 (includes the model A) don't have the usb polyfuses..
[12:09] * DenBeiren (~Denbeiren@ has joined #raspberrypi
[12:09] <steve_rox> wonder if that means if it shorts the thing is destroyed
[12:09] <gordonDrogon> Even the Rev 1's with the polyfuses (which I have) can cause the Pi to reboot when I plug in a high current display. The polyfuses aren't quite quick enough for the surge of the LED backlight coming on.
[12:10] <gordonDrogon> a usb short - should trip the main 700mA polyfuse...
[12:10] <steve_rox> oh they kept one polly
[12:10] <gordonDrogon> curciously enough, a 3.3v short doesn't always cause the Pi to reboot (as I've found out myself recently) it needs a proper power cycle...
[12:10] <steve_rox> i still got my rev 1 board
[12:10] <rpitin> gordonDrogon: high powered usb devices need to be plugged in via a powered usb hub because they draw too much power?
[12:11] <gordonDrogon> rpitin, if they're going to draw more than 2-300mA then yes. You might get away with a 2-headed USB power lead though - I use that for some 3G+GPS modules I'm testing..
[12:12] <seba-> Triffid_Hunter, ok i'm powering now directly on GPIO like you
[12:12] <rpitin> gordonDrogon: ya, i miss read your sentence, thought you were asking a question, but you were making a statement, my bad.
[12:12] <gordonDrogon> rpitin, no probs :)
[12:13] <gordonDrogon> I think you can still do a lot with the Pi's USB - you just need a little bit of care - it's still a $35 PC though :)
[12:14] <[Saint]> here's something I've been wondering - what color are you guys' VGA-out?
[12:15] <[Saint]> Am I the only person in the world with a black one?
[12:15] <gordonDrogon> there isn't VGA out on the Pi.
[12:15] <[Saint]> blargh - I derped a term.
[12:15] <gordonDrogon> compost video is yellow.
[12:15] <gordonDrogon> :)
[12:15] <[Saint]> composite - yes.
[12:15] <[Saint]> Mine's black.
[12:15] <Triffid_Hunter> seen a few photos of pis with black ones
[12:15] <[Saint]> Awwww...
[12:16] <gordonDrogon> 3.5mm jacks are either black or blue (mostly blue on the Rev 2's from what I've seen)
[12:16] <[Saint]> yeah - the 3.5mm is black, as is the composite.
[12:16] <gordonDrogon> off that they used black on the video out - yellow is a standard colour for it - but maybe they ran out of yellow one day :)
[12:16] <[Saint]> On my other pi(s), they're yellow...but on the one I have here now, its black.
[12:17] <[Saint]> I hadn't seen that before. Got curious.

[12:29] <Jx8p> dist-upgrade produced a sane report of things it wanted to do, well it did want a load of new packages installed, mostly themes and stuff
[12:29] <gordonDrogon> dist-upgrade ever now & then is generally ok.

[12:31] <Jx8p> i sincerely hope my 'TURBO' overclock didn't ruin the SD card as raspi-config warns
[12:32] <Jx8p> it takes so long to flash the image to SD <_<
[12:32] <gordonDrogon> dist-upgrade can install new files that an ordinary upgrade can't.
[12:32] <[Saint]> ruin it? no. trash your data? Ohhhh yes - yes, that can certainly happen.
[12:32] <Jx8p> wonder how feasible it is that the overclock ruined the dpkg file, causing the segfault

[13:10] <rpitin> There are a lot of blogs with a range of configs but thats the one that worked for me.
[13:10] * KindOne (~KindOne@colchester-lug/silly-fool/donut) has joined #raspberrypi
[13:11] <Jx8p> setting bs=4m has the progress indicator declaring only 7 minutes until it's written :)
[13:11] * Tenkawa (~Tenkawa@unaffiliated/tenkawa) has joined #raspberrypi
[13:11] <Tenkawa> well... so far so good on slackwarearm on the pi
[13:11] <rpitin> Jx8p: that's better.
[13:12] <Jx8p> a lesson learnt about that 'turbo' overclock
[13:13] <rpitin> Saint: Macs marketing strategy was to successfully make Joe average feel special and part of the technocratic elite (imaginary) by way of purchase choices.
[13:14] <Gadgetoid> Right I've pulled the lovely coil from the PCB, and the transistor next to it??? looks like the ground of the coil is connected to the middle of the transistor, the other two legs loop around through capacitor or some weirdness, and then magic happens
[13:14] <Triffid_Hunter> Jx8p: fwiw, setting blocksize should have only the tiniest impact on performance. if it really makes that much difference, your OS's kernel is turning off write cacheing for that disk for some reason
[13:14] <gordonDrogon> Gadgetoid, Heh... the primary is part of the oscillator.
[13:14] <rpitin> Saint: Their marketing is really very good.
[13:15] <Gadgetoid> gordonDrogon: I can't find a good schematic to tell me how on earth it all works
[13:15] <Triffid_Hunter> Jx8p: I'd have a stern chat with it about that if I were you
[13:15] <Tenkawa> blocksize on what?
[13:15] <Triffid_Hunter> Jx8p: if it does that when the disk is mounted, you'll have really slow access to all SD cards for all operations, not just dd
[13:16] <Triffid_Hunter> Tenkawa: Jx8p's OSX machine was writing to SD card in super slo-mo, apparently tweaking dd blocksize gives it the kick in the rear it needed
[13:16] <gordonDrogon> Gadgetoid, if you remove the transformer - and connect the primary from +5v through the coil to the collector of a ulm2803 then you can control the frequency with the GPIO clock oscillator on the Pi ...
[13:16] <gordonDrogon> Gadgetoid, or softTone :)
[13:16] <Tenkawa> yeah... i'm not suprised
[13:16] <Tenkawa> default dd is slower than molasses
[13:16] <Jx8p> we're talking 3 hours and 53 minutes of difference
[13:16] <Tenkawa> you always need to tweak bs=
[13:17] <Gadgetoid> gordonDrogon: That would be cool!
[13:17] <Tenkawa> unless you have specifuc use case to not use it
[13:17] <Tenkawa> er specific
[13:17] <Gadgetoid> Doens't help that the tip of my soldering iron is corroded to the point of blackness, and it doesn't get hot
[13:18] <Tenkawa> Gadgetoid: ouch...
[13:18] <Gadgetoid> Must dig up my spare, going to solder some headers onto the transistor I cut from the PCB and try to re-use it for a fixed frequency
[13:18] <gordonDrogon> the bs= (or ibs=, obso=) in dd is often set to 4K, so it improves efficiency if you can make it bigger, as it will buffer more in memory.
[13:18] <Jx8p> woo, done
[13:18] <Gadgetoid> gordonDrogon: It's got to be over 20 years old and it spend a lot of time in a loft of shed, so I'm not surprised
[13:18] <Triffid_Hunter> I thought default was 512b
[13:18] <Tenkawa> depends on build/os
[13:18] <Gadgetoid> Think it's probably about time I bought a good one, and a bench power supply
[13:18] <rpitin> Jx8p: that sounded easier than expected!
[13:18] <gordonDrogon> Gadgetoid, er - my iron was over 35 years old when it finally expired - it was a quality one though :)

[13:22] <rpitin> Jx8p: maybe a little bit less than last time1
[13:22] <gordonDrogon> Jx8p, I gave up on overclocking months back. not missed it.
[13:22] <gordonDrogon> right. buns to make!
[13:23] <rpitin> gordonDrogon: om nomnom. Id offer you a custard and raspberry tart, but i ate them all.
[13:23] * DenBeiren (~Denbeiren@ has left #raspberrypi
[13:24] <Jx8p> i can't not overclock. I love OC'ing my graphics cards. Get some more litecoin mined

[13:39] <Jx8p> cellardoor, yep. you can always exchange them at btc-e or similar places, though
[13:40] * Datalink (~Datalink@unaffiliated/datalink) has joined #raspberrypi
[13:40] <cellardoor> Jx8p: ah cool. Bit random, but can you explain a few things about Bitcoin for me that I can't get my head around. - If I have multiple computers how do I keep all my money 'in one place' or registered to me. and also with this mining.... free money?
[13:42] <Jx8p> your 'wallet' is just an abstraction, really what your wallet is, is just a private key that allows you to spend your bitcoins. so you can just dump your private key and import to another PC. as for mining -- at the moment, yeah, free money :) but you'll need specialist hardware for it soon, rather than just an array of overclocked Radeon 7970s
[13:42] <rpitin> cellardoor: use the same wallet between systems, mining is an exchange of processing power over time (and electricity) for bitcoin
[13:43] <rpitin> not free money!

[13:43] <Hans-Martin> funny I was just following the #bitcoin channel and switched over here, and something just looked familiar...
[13:44] <rpitin> even if its not your processing power and electricity, its costing someone.
[13:44] * DenBeiren1 (~Denbeiren@ has joined #raspberrypi
[13:45] <Jx8p> i've already paid off my 7970 from profits. i suppose it's free only relative to "I would be running these machines anyway". although profit? in my case, yes, and i pay a lot for electricity. i have about 2 months to go before my cards are all paid off
[13:45] <cellardoor> Jx8p: Thanks, think I am getting it a bit more now :) haha I have LiteCoin on my netbook at the moment so doubt I will get much from this Mining thing :P

[13:46] <Armand> So... I bought my 60 USB ports last night.
[13:46] <rpitin> Jx8p: you're donating a % of your processing power, time and electricity in exchange for bitcoin.
[13:46] <rpitin> Jx8p: so not free!
[13:47] <Jx8p> yeah rpitin. i suppose then its a not a question of 'free', but rather, 'do i make a profit from it'
[13:47] <rpitin> Jx8p: Yeah, that's a return on investment.
[13:47] <rpitin> Sorry, my inner businessman is coming out.
[13:47] <rpitin> But its important to know, its still a system, just one of a different nature.
[13:48] <cellardoor> Jx8p: what's the difference between Solo Mining and Pool Mining?
[13:48] <Jx8p> well, so far my RoI is shaping up to be pretty good :) especially when i've got my mining rigs all headless and automated.
[13:48] <rpitin> cellardoor: Mining by yourself vs joining a grid/cloud
[13:49] * Kane (~Kane@ has joined #raspberrypi
[13:49] <Jx8p> cellardoor, in solo mining...solo mining is not really a good idea unless you have swathes of computing power. it has unpredictable returns
[13:49] * bortzmeyer (~stephane@2a01:e35:8bd9:8bb0:91f4:1622:9ab4:8385) Quit (Ping timeout: 246 seconds)
[13:49] <rpitin> Not sure of the difference in efficiency vs solo / grid
[13:49] <Kane> o/
[13:49] <rpitin> \0/
[13:50] <Jx8p> i run a pool which charges no fees, thus the pool is equally efficient as solo, but more predictable. payouts are still done per-block-found, but it's the whole pool's power finding them
[13:50] <cellardoor> Jx8p: well since I am a very mobile person with a netbook, I think Pool mining is the way to go... question is which pool to join as I see server and U/N P/W fields
[13:50] <rpitin> Jx8p: they may borrow some of your processing power for their own mining efforts.
[13:50] <cellardoor> This stuff is fascinating :)
[13:50] <rpitin> Not sure on that one, but its a hunch.
[13:51] <Jx8p> since you're here cellardoor i'm going to plug my pool :)
[13:51] <Jx8p> you can visit that page to get pool stats, or if you want to connect, use that URL as server in the miner, username is your litecoin wallet address, p/w is whatever you want
[13:52] <Triffid_Hunter> cellardoor: last time I checked, bitcoin mining is unlikely to pay off the cost of equipment needed these days
[13:52] <rpitin> Just dont use the same password as your key
[13:52] <cellardoor> Jx8p: okay :)
[13:52] <cellardoor> Triffid_Hunter: Ah but I have SWATHES of computers... they just are not very powerful :P
[13:53] <cellardoor> Jx8p: not working :(
[13:53] <Jx8p> oh, what's it saying? :(
[13:53] <rpitin> cellardoor: you could donate some of that processing power to charity via the World Community Grid, it pays karma and good feelings instead of bitcoins

[13:54] <Jx8p> i use a weird port for various reasons

[13:54] <Jx8p> if you have free electricity, spare machines, and don't mind the heat? mining is the way to go

[13:55] <rpitin> I hope you boys are offsetting your CO2 omissions!
[13:55] <Armand> I just hope my employer doesn't object to a max draw of around 700W+ @ 30A :P
[13:55] <Armand> I'm sure it won't be a problem in a DC. ;)
[13:56] <cellardoor> Jx8p: is the LiteCoin pool address the server IP, or with the Port on the end too?
[13:56] <Jx8p> litecoin pool address is
[13:56] * Cykey (~textual@modemcable119.94-162-184.mc.videotron.ca) has joined #raspberrypi
[13:56] <Jx8p> just copy-paste the url in, no need to reduce to IP address:port format
[13:56] <rpitin> I wonder what the conversion rate between power consumption of mining bitcoin vs the cost of planing a tree that produces an equal carbon offset

[14:03] <rpitin> Lubuntu can be a bit fiddely, but you can usually get it to run most things.
[14:03] <cellardoor> Jx8p: Probably not, as I don't know what that is

[15:15] <AdvancedNewbie> Then wpa_supplicant should skip "DHCPDISCOVER"
[15:15] <AdvancedNewbie> then you can dhclient if you want
[15:15] <AdvancedNewbie> Or just remain using the static ip as you've setup.
[15:18] <featheredfrog> thanks for the insights. sorry about the spam.
[15:19] <AdvancedNewbie> Hope that helped... heh
[15:20] <featheredfrog> why can't this be easy like rh-family distros ?

[15:25] <Henesy> zensiert_, "sudo mount /dev/youhdd/ /directory/to/mount/to"
[15:25] <AdvancedNewbie> Try 'df' to list devices
[15:26] <zensiert_> ah ok, "df" helps
[15:27] <zensiert_> but how can i create a mount point?
[15:27] <AdvancedNewbie> mkdir /directory/to/mount/to
[15:27] <zensiert_> mkdir = make directory?
[15:27] <AdvancedNewbie> Yup
[15:27] <AdvancedNewbie> Make it, then mount to it
[15:28] <zensiert_> i'm german and have slightly trouble with english shortcuts
[15:28] <Henesy> "sudo fdisk -l" also works for listing filesystems/drives
[15:28] <AdvancedNewbie> You probably want to put this in the media or mount directories.
[15:29] <zensiert_> where's thr difference?
[15:29] <zensiert_> or why can't be both in one directory
[15:29] <zensiert_> ?
[15:29] <AdvancedNewbie> media is more for removable devices
[15:29] <AdvancedNewbie> Or sometimes removable media such as cd's
[15:30] <Henesy> /mnt is for temporary stuff whereas /media is more for devices or more permanent things
[15:30] <zensiert_> ok
[15:30] <zensiert_> so my usb hard disk is a "media"?

[15:32] <zensiert_> found your channel athttp://elinux.org/ELinuxWiki:Irc
[15:33] <zensiert_> what do the to & stand for?
[15:33] <AdvancedNewbie> It's so you can pass two commands at once.
[15:33] <AdvancedNewbie> Well, one after another.
[15:34] <zensiert_> you mean first the mkdir-order and then the mount-order?
[15:34] <zensiert_> command*
[15:34] <AdvancedNewbie> Yeah, left to right

[15:40] <Henesy> hm
[15:40] <Henesy> not exactly
[15:41] <Henesy> you could
[15:41] <Henesy> is there a specific name you want for your drive in media?
[15:41] <Henesy> I'll give an example regardless from my experience
[15:42] * WorkGroup (~workgroup@unaffiliated/workgroup) has left #raspberrypi
[15:42] <Henesy> mmcblk0p2 is my root partition on my pi, I don't need to mount anything there, as it is already done on startup
[15:42] <zensiert_> how about "USB_harddisk"?
[15:42] <Henesy> so i want to mount my flashdrive
[15:42] <Henesy> sure
[15:42] <zensiert_> ok
[15:42] <zensiert_> wait
[15:43] <zensiert_> mmcblk0p2 is already on the pi?
[15:43] <zensiert_> like hardware-based?
[15:43] <Henesy> so what i personally did: "sudo mkdir /media/BACKUPS && sudo mount /dev/sda1 /media/BACKUPS"
[15:43] <Henesy> mmcblk0 is the SD card, which is where the OS is on the pi
[15:43] <Henesy> if your pi is booting into say, raspbian
[15:43] * Dakota (~Dakota@prim.milamber.ca) has joined #raspberrypi
[15:43] <Henesy> then it is using the SD card right?
[15:44] <zensiert_> ... you actually created a directory called "BACKUPS"... ok
[15:44] <zensiert_> yep
[15:44] <Henesy> when raspbian boots in a typical setup I believe, mmcblk0p1 is the boot partition and mmcblk0p2 is the root filesystem
[15:45] * LostInInaka (~Unknown@unaffiliated/lostininaka) has joined #raspberrypi
[15:45] <Henesy> and if you have a running system on the pi, then neither of those matter on it, because the pi is already using them
[15:45] * ParkerR (ParkerR@unaffiliated/parkerr) has joined #raspberrypi
[15:45] <zensiert_> didn't even know these exist...
[15:45] <zensiert_> ok, got it
[15:45] <Henesy> here's some food for thought
[15:46] <zensiert_> so all i need now is to create a mount point for my drive and mount it?
[15:46] <AdvancedNewbie> Yeah, "mmcblk0p{partition number}"
[15:46] <zensiert_> feed me...
[15:47] <Henesy> on your main computer the first hard drive will typically be called /dev/sda. Since the SD card isn't a scsi drive/hard drive it needs a different name. mmcblk0 is the perfect candidate for whatever reason (someone else could exlain that) and so the SD card is called mmcbl0 instead of /dev/sda. If on your main computer right now you decided to do "fdisk -l" you would more than likely get a /dev/sda or /dev/hda list of resu

[15:54] <zensiert_> it tells mi: /dev/sda /dev/sda1
[15:54] <zensiert_> so what does it tell me...?
[15:54] <ShadowJK> mmc = multimediacard, and old standard for memory cards, same shape as SD. SD is kinda a side development that drowned out the original mmc, so the name stuck.. and blk = block, a block device that apps and filesystems can treat as a harddrive
[15:54] <AdvancedNewbie> That you can mount using /dev/sda1

[15:55] <Hans-Martin> yup
[15:55] <zensiert_> now you got me... cunfused
[15:55] <AdvancedNewbie> You want to mount sda1
[15:55] <Hans-Martin> sda includes the partition table
[15:56] <Hans-Martin> sda1 is the first partition
[15:56] <AdvancedNewbie> Right.
[15:56] <Henesy> /dev/sda encompasses the whole family, /dev/sda1 and /dev/sda2 etc are the annoying kids
[15:56] <AdvancedNewbie> sda contains information on how many partitions there are, etc.

[15:56] <zensiert_> ok now i think i will remember it... thx

[15:57] <AdvancedNewbie> So Henesy's example should work for you ( "sudo mkdir /media/BACKUPS && sudo mount /dev/sda1 /media/BACKUPS" )
[15:57] <AdvancedNewbie> Then just cd /media/BACKUPS
[15:57] <AdvancedNewbie> And you should see the contents of your USB HDD
[15:58] <Henesy> ^yup
[15:58] <AdvancedNewbie> Remember: linux is case-sensitive
[15:58] <Henesy> ^windows is NOT
[15:58] <buzzsaw> and thats *one* of its problems :-)
[15:59] <AdvancedNewbie> Windows, yep.
[15:59] <AdvancedNewbie> ;)
[15:59] <zensiert_> what das case-sensitive mean?
[15:59] <AdvancedNewbie> it means cd /media/BaCkUpS will not work.
[15:59] <Henesy> this leads to complication if you have a dosemu running and you try to cd to a directory that has another directory in the same spot and one is named Folder and the other is named folder. dosemu would only use one, and that would be the one favouring caps i believe

[18:09] <seba-> Gadgetoid, what do you want to do?
[18:09] <gordonDrogon> yes. that's all you need - just +5v -> coil -> driver -> 0v
[18:09] <gordonDrogon> and toggle the input at a set frequency.

[18:10] <Gadgetoid> seba-: I'm trying to generate AC and step it up to 100V to drive some EL wire
[18:10] <Gadgetoid> I have a coil with the right ratio, presumably, to convert 6v to 100v
[18:10] <gordonDrogon> parallel up a few of them if you want more current.
[18:11] <Gadgetoid> gordonDrogon: I'll have to fish out a uln2003 then
[18:11] <seba-> Gadgetoid, why don't you generate directly 100 V
[18:11] <pksato> EL wire?
[18:11] <Gadgetoid> Still not sure how to make it work, but can only experiment!
[18:11] <seba-> without the transformer
[18:11] <seba-> :)
[18:11] <gordonDrogon> I suspect the original drove it with a modified swuare wave anyway.
[18:11] <Gadgetoid> seba-: Don't have the parts, I don't think, and only need a very, very low current
[18:12] <Gadgetoid> gordonDrogon: the original used a cluster of caps and resistors to set up a poor mans oscillator
[18:12] <seba-> Gadgetoid, you just need a choke/inductor, a diode and a mosfet/transistor
[18:12] <buzzsaw> okay so I am no electronics guy but I was wondering... What would happen if you run +15v to the hod side and +10v to the ground? Does the 15v transfer to the 10v and give you the same as a 5v?
[18:13] <gordonDrogon> the 'hod side' ?
[18:13] <buzzsaw> s/hod/hot
[18:13] <gordonDrogon> hot side of what?
[18:13] <Armand> yo momma ?
[18:13] <Armand> Sorry..
[18:13] <buzzsaw> anything? by hot I mean posative
[18:13] <seba-> Gadgetoid, if you make the boost converter work in discontinous mode, the efficiency will be quite high and duty cycle low :)
[18:14] <seba-> Gadgetoid, but you would need a zener to set the voltage
[18:14] <Gadgetoid> Going to try a darlington
[18:14] <seba-> Gadgetoid, if otoh you would make a continous mode, which is easier to control, you would need higher duty cycles and it will have a higher consumption
[18:15] <seba-> Gadgetoid, i've generated 1 kV out of 5 V without problems
[18:15] <seba-> Gadgetoid, with discontinous mode of course :)
[18:15] <Grievre> How rare is it for people to build mains->DC power supplies as an unregulated switcher and then a linear regulator? Seems like it combines most of the advantages of a linear supply but without the need for a massive transformer
[18:16] <seba-> Grievre, not really, the best is to have a high frequency transformer, which is small
[18:17] <seba-> Grievre, but gives insulation
[18:17] <gordonDrogon> Grievre, my "bench" PSU is just that. 240-9v transformer than a 7805 :)
[18:17] <Gadgetoid> All this voltage madness!
[18:17] <gordonDrogon> I keep meaning to make something better, but it still works and I can't be bothered..
[18:18] <seba-> Gadgetoid, you can get all parts in a CFL lamp
[18:20] <gordonDrogon> more fun building it :)
[18:20] <Grievre> seba-: Er, how is that not what I described?
[18:20] <Grievre> o.o
[18:21] <seba-> Grievre, i don't know, switchers have various topologies, i thought maybe you were talking about the one we were talking, which is uninsulated
[18:21] <Grievre> Oh wait I'm asking in the wrong channel x.x

[18:29] <gordonDrogon> and check the Pi's output too ...
[18:30] <Gadgetoid> Checking with a whole lot of LEDs
[18:31] <gordonDrogon> Hm. I could just buy a 12v toroidal transformer for this lamp and put it in the loft above the lamp and feed 12v down into it...
[18:33] <gordonDrogon> then again after checking the prices, it would be cheaper to buy a new lamp.

[19:21] <Gadgetoid> It's running off 6v
[19:22] <SpeedEvil> you will
[19:22] <Gadgetoid> It works fine as long as I drive the transistor from the input voltage, anything else and its unresponsive

[19:24] <Gadgetoid> There's always the chance the schematic I'm working from is horribly wrong!
[19:24] <SpeedEvil> you will need to drive at least the PNP transistors through some stage to increase the voltage to the supply volytsgre
[19:25] <SpeedEvil> as otherwise they are permenantly turned on, as 6-3.3 = 2.7 v , which will turn them in

[23:26] <gordonDrogon> evening all.
[23:26] <Gadgetoid> gordonDrogon: you were right all along, I just didn't fully understand you
[23:26] <gordonDrogon> a-ha :)
[23:27] <Gadgetoid> gordonDrogon: I now have EL wire running from my Pi, with softTone controlling the brightness
[23:27] <gordonDrogon> neato! :)
[23:27] <Gadgetoid> Gonna make it pulsate and shoot a video

[23:28] <Gadgetoid> Can drive the frequency up to about 1500, and down to about 100 for a massive range of visible light
[23:28] <rpitin> yes, videos, please do, much easier than making heads and tails of backscroll
[23:29] <des2> We already have a massive range of visible light, we call it the Sun
[23:29] <rpitin> H boards, coils and problem displacement is all backscroll will tell me :(
[23:29] <gordonDrogon> Gadgetoid, yes - the higher the frquency - up to the limit of the transformer, the more efficient it ought to be, so the brighter it will be..
[23:29] <rpitin> des2: trollollol
[23:29] <Gadgetoid> gordonDrogon: I think it's two fold- as EL wire also glows brighter at higher frequencies
[23:30] <gordonDrogon> doesn't surprise me.
[23:30] <Gadgetoid> Yeah, it shoots out more photons!
[23:30] <Gadgetoid> Got it pulsating with softTone now
[23:30] <gordonDrogon> the only thing to watch out for is the back emf from the primary coil - the diode in the uln2803 ought to protect it though, so make sure it's connected up.
[23:32] <Gadgetoid> gordonDrogon: I'm driving the coil through an H bridge anyway
[23:32] <gordonDrogon> ah, not the uln. ok.
[23:32] <Gadgetoid> Well, yes, the ULN too
[23:32] <Gadgetoid> It's a bit of a crazy complicated mess
[23:32] * gko (~user@114-34-168-13.HINET-IP.hinet.net) Quit (Ping timeout: 256 seconds)
[23:32] <Gadgetoid> The ULN takes 1 input, inverts it and drives two outputs so they toggle the two sides of the H bridge
[23:33] <Gadgetoid> I don't know how to wire the coil to just the ULN
[23:33] <gordonDrogon> you could write a version of soft-tone that uses 2 outputs in push-pull mode - that will effectively double the voltage through the primary ...
[23:33] <Gadgetoid> Got a pretty strong flow from this, I might hook up some other types of wire, or more wire, and see how it goes
[23:33] <Gadgetoid> glow*
[23:33] <Gadgetoid> Tried to shoot a video, camera says: NO
[23:34] <gordonDrogon> you'd keep the enable high into the H bridge and toggle each drive pin in opposite ways.
[23:34] <rpitin> :(
[23:34] <rpitin> You sir need another raspberry pi with a webcam and motion installed.
[23:34] <gordonDrogon> good luck - I'm off to bed. long night - tired - was out at a dance earlier, just watched Dr Who on iPlayer and the clocks go forward...

[23:38] <hays> well it was on my desk and it seems to be gone now
[23:39] <hays> i think i left it there too long and it got "put away"
[23:39] <des2> Do you have a cat ?
[23:39] <rpitin> or worse yet, a wife?
[23:39] <hays> both!
[23:39] <rpitin> well, you're in trouble
[23:39] <hays> yep
[23:40] <rpitin> check the fridge
[23:40] <des2> The cat took it because you were spending too much time with it
[23:40] <hays> i need to find a picture of the box it was in
[23:40] <des2> (that reason works for wives too)

[23:47] <Gadgetoid> Weird, my electroluminescent disk seems to change colour slightly
[23:47] <Gadgetoid> It goes from blue to blue green

[23:52] <rpitin> hehe

[23:56] <rpitin> Gadgetoid: so school shmool, it gives you some skills to use to learn how to learn
[23:56] <Gadgetoid> rpitin: Hahaha!
[23:56] <Gadgetoid> What's the agency?
[23:57] <rpitin> Gadgetoid: would rather not say, tinkering with hardware and stuff may scare the wildlife/customers.
[23:57] <Gadgetoid> rpitin: Fair enough! curious customers
[23:57] <rpitin> Gadgetoid: joe average associates that stuff with hacking, and thats evil and bad and stuff right? so yeah.
[23:58] <chupacabra> lol
[23:58] <Gadgetoid> I work for an online marketing agency, so I wanted to know if I'd come across you
[23:58] <Gadgetoid> Haha, if it weren't for "hacking" we wouldn't be able to fix peoples broken-as-hell web servers, or secure ours
[23:58] <rpitin> Gadgetoid: oh doubt it, we keep a low profile. Client portfolio of about 150 people. Taking it slow and steady as our larger competitors bite the dust
[23:58] <Gadgetoid> rpitin: sounds familiar
[23:59] <rpitin> Gadgetoid: Yeah I know that, you know that, but they don't know that.
[23:59] <Gadgetoid> Sometimes I wish I could do this without the clients
[23:59] <Gadgetoid> I say??? as my comments about clients get eternally committed to an IRC log :D
