[0:00] <RavenII> MarkSX, oh I know man, but the reality is, that it IS a better device on paper...I was just wondering the same thing as you...
[0:00] <RavenII> Why does the Pi get so much attention...
[0:00] <RavenII> it's a fair question.
[0:00] <MarkSX> RavenII, It would seem that way, I'm kinda keen to get one to try it out
[0:00] * Albori (~Albori@64-251-150-248.fidnet.com) has joined #raspberrypi
[0:00] <ShorTie> because of folks like us
[0:00] <ShorTie> ie: the community
[0:00] <MarkSX> I prefer the BeagleBone anyway, Doesnt corrupt storage nearly as much
[0:00] <RavenII> I've got 2 Pies so far...been looking for...wait, you have that issue too?
[0:01] <MarkSX> Corruption ?
[0:01] <RavenII> Dude, I've tried so many different mSD cards...
[0:01] <RavenII> yeah.
[0:01] <MarkSX> Isnt it like a running joke ?
[0:01] <RavenII> Overlocked, not overclocked.
[0:01] <Triffid_Hunter> RavenII: marketing.. also the odroid C1 was released to directly compete with the RPi, there was nothing in the pi's price range with even vaguely simliar abilities before it came out
[0:01] <bhez> I have that problem too on multiple pi's. not just with the SD card, but also with an external USB hard drive
[0:01] <RavenII> I mean, for $35, it's...tolerable?
[0:01] <RavenII> understandable?
[0:02] <ShorTie> need a better power supply and/or micro-usb cable to fix sdcard corruption
[0:02] <MarkSX> Its a hobbiest tool, nothing more you can live with corruption
[0:02] <zleap> there are lots of different single board computers, select your project / needs then get the board that is most suited to that needf
[0:02] <niston> I have yet to experience a corrupted SD card
[0:02] <niston> although I'd prefer not to.
[0:02] <RavenII> zleap, yeah, I'm just getting into it...
[0:02] <MarkSX> Ive got 14 RPI's hooked up to TV's purely doing h264 playback of videos in a loop using OMX
[0:02] <zleap> ok
[0:02] * c00ljs (~c00ljs@ Quit (Remote host closed the connection)
[0:02] <zleap> nice
[0:03] <RavenII> Funny, I grabbed an Ouya to do the same thing with...talk about a piece of crap.
[0:03] * _Ulan1 (~Thunderbi@ Quit (Remote host closed the connection)
[0:03] <RavenII> 0 support for mpeg2.
[0:03] <MarkSX> RavenII, *hangs head in shame, i was in the kickstarter*
[0:03] <RavenII> MarkSX, Amazon is paying $76 for them in excellent condition..that's where mine went.
[0:03] <MarkSX> For real ?
[0:04] <MarkSX> Arent they pretty much all in Excellent condition
[0:04] <PovAddict> lol
[0:04] <PovAddict> unused
[0:04] <RavenII> https://www.amazon.com/gp/tradein/cart.html?ie=UTF8&asin=B0050SZD18&ece=
[0:04] <RavenII> hahaha
[0:04] <MarkSX> I admire what Ouya attempted to do and I backed them 100% but their hardware was just too underpowered
[0:04] <RavenII> That's funny.
[0:04] <RavenII> No no, it wasn't bad hardware...it was their lack of...support?
[0:05] <RavenII> They didn't deliver on a lot of things.
[0:05] <RavenII> from what I heard anyhow.
[0:05] <PovAddict> can I run a raspberry pi image in qemu or something?
[0:05] <Triffid_Hunter> hm I never got any SD corruption on mine
[0:05] * timtaler (timtaler@harpy.gmake.de) has joined #raspberrypi
[0:05] <MarkSX> I think it was alot of things in the end I just never felt the UI to be very responsive
[0:05] <RavenII> I haven't on my B+...yet.
[0:05] <MarkSX> and with a shitty UI your off to a bad start
[0:05] <MarkSX> Its why I run Plex and such on overkill gear so I have fluid UI's
[0:06] <Triffid_Hunter> then again I did this --> http://triffid-hunter.no-ip.info/101_0120_mlcc.jpg <-- to it and power it from a 2.5A tablet charger via the GPIO header
[0:07] <MarkSX> Nice
[0:07] <ShorTie> easier to just get some micro-usb ends and use some real wire to your power supply .. :)~
[0:07] * ant_thomas (~ant_thoma@cpc13-blbn9-2-0-cust272.10-1.cable.virginm.net) Quit (Ping timeout: 264 seconds)
[0:08] <ShorTie> replace those ineffient micro-usb cable with some 18ga wire makes a world of difference, imho
[0:08] * Macuser (~textual@unaffiliated/macuser) has joined #raspberrypi
[0:09] <Triffid_Hunter> those little brown rectangles I highlighted are 10uF ceramic capacitors if anyone's curious

[0:12] <RavenII> Wow... Talk about informative, of course most of these things mean nothing in real world, but still...

[0:13] <zleap> finally
[0:13] <RavenII> Huh?
[0:13] <zleap> i got it working, but one huge faff
[0:13] <RavenII> oh.
[0:13] <MarkSX> Im seeing alot of green
[0:13] <PovAddict> MarkSX: green is where odroid wins
[0:13] <zleap> i ended up editing the config file manually
[0:13] <PovAddict> afaik
[0:14] <zleap> it would help if we could see the password for the wifi, when entering, some applications do allow this, show password
[0:14] <RavenII> MarkSX, but it is CLEARLY biased as in the GPU tests...the C1 gets dusted by the Pi...
[0:14] <RavenII> I mean...almost 4x over.
[0:14] * icecube45 (~icecube45@unaffiliated/icecube45) has joined #raspberrypi

[0:27] <clever> PovAddict: manualy picking versions and forcing them with dpkg may cause issues down the road
[0:27] <clever> so your next step is to apt-get update and apt-get upgrade, so it gets the right versions
[0:32] * ]DMackey[ (~n2dvm@cpe-67-246-122-255.twcny.res.rr.com) has joined #raspberrypi

[0:35] <ssvb> RavenII: so just disregard what I said
[0:35] <trinque> anyone know why a pi would get stuck after running 'reboot' ?
[0:35] <trinque> old firmware?
[0:35] <jimvideo> You are saying that the studio audience has Nerf Balls? :D
[0:35] <PovAddict> trinque: reproducibly?
[0:35] <trinque> I have to sometimes do the power plug dance to bring it back
[0:36] <trinque> PovAddict: yeah I might be able to; I have about 50 of them attached to printers in the field
[0:36] <PovAddict> ah
[0:36] <PovAddict> just making sure it wasn't something you encountered only once just now :)
[0:37] <trinque> nah, I've seen it quite a few times
[0:37] <trinque> not a huge deal, as we can just get someone to cycle it

[0:59] <PovAddict> I'm using minibian which didn't even have raspi-config installed by default :D
[0:59] <PovAddict> can I emulate a raspberry pi in qemu or something? would be handy to prepare disk images on the computer
[0:59] <ShorTie> minibian ??
[0:59] * peeps[work] (~Sir@23-120-228-29.lightspeed.austtx.sbcglobal.net) has joined #raspberrypi
[0:59] <PovAddict> ShorTie: minibian is raspbian with less packages installed by default, pretty much
[1:00] <PovAddict> it's a minimal raspbian image

[6:23] <ShorTie> the best multibooter is multiple sdcards .. :)~
[6:23] <niston> interesting vpn connection. ping times are much lower when there's data transferring over the link...
[6:24] <ICantCook> remm: I compiled it overnight and tested PSX/GBA/SNES. All worked. N64 failed to load my roms but haven't had time to look at it yet, probably my bad
[6:25] <abnormal> ShorTie, no the best multibooter is multiple pi's with each disto in each pi...
[6:25] <ICantCook> remm: You can get USB adapters for n64. My mate made one. There are drivers out there, never tried them on rPI though
[6:26] <ICantCook> I don't seethe appeal for you guys to use old controllers. X360, etc are more comfortable and ergenomic
[6:26] <abnormal> we still use old computers, they never die...
[6:27] <remm> i just bought a n64 usb controller
[6:27] <remm> but its for 'windows'
[6:27] <remm> didnt realise
[6:27] <abnormal> lol
[6:27] <ICantCook> lol
[6:27] <ICantCook> the n64 controller in particular never made sense to me
[6:27] <abnormal> you mean, "windex"
[6:27] <ShorTie> remm, have you plugged it into the pi to see what dmesg says about it ??
[6:28] <remm> i havent
[6:28] <remm> i just ordered it :p
[6:28] <abnormal> lol
[6:28] <ShorTie> oh, ok
[6:28] <remm> it might work

[6:29] <niston> ah. windows with a game pad - a true wintendo.

[6:30] <remm> ive got snes usb controller ripoffs that are usb
[6:30] <remm> but the dpads suck shit
[6:30] <seitensei> Do those eMMC uSD adapters for the Odroid C1 work with the Pi?
[6:31] <puff> Hi.
[6:31] <puff> I have a project in mind and I'm trying to figure out if raspberrypi is the right approach. Anyone got a minute?
[6:32] <seitensei> puff: Don't ask to ask, just ask
[6:32] <puff> seitensei: Okay then. I want to build a pit bbq/smoker with multiple sensors. Is raspberrypi the right platform?
[6:32] * ShorTie thinkz, tic-toc tic-toc
[6:32] * thomasreggi (~thomasreg@ool-44c25559.dyn.optonline.net) has joined #raspberrypi
[6:32] <seitensei> puff: What do you need the pi for?
[6:32] <remm> wont the pi melt
[6:33] <puff> seitensei: 1-2 ambient temperature sensors, several meat probe thermometers, air flow, smoke density, humidity.
[6:33] <ShorTie> just so you don't bbq it too...
[6:33] <seitensei> Okay, but why the pi? What other platforms have you looked at?
[6:33] <remm> just cause its called a raspberry pi doesnt mean you cook it =)
[6:33] * thomasreggi (~thomasreg@ool-44c25559.dyn.optonline.net) Quit (Remote host closed the connection)
[6:33] <ali1234> derp.
[6:33] <puff> Why the pi? Because it's been 20+ years since I did any C code.
[6:34] <puff> I've heard pi supports higher level languages, like python.
[6:34] <ali1234> pi is pretty good platform for this, because you will want a rich user interface
[6:34] <seitensei> puff: I would personally use the BeagleBone Black if I had to do a lot of sensor
[6:34] <seitensei> but if you need a graphical UI, the pi pulls more in the GPU department
[6:34] <ShorTie> ah, that stupid snake
[6:34] <ali1234> pi has i2c, so just get digital sensors
[6:35] <puff> I could use an android app or something for the UI, or even a web app, assuming the pi can run oen.
[6:35] <ShorTie> pi can run the Arduino-ide
[6:35] <puff> Are there limitations in terms of which sensors work on which platforms?
[6:36] <seitensei> puff: you have digital and analog
[6:36] <seitensei> digital is fine for pi
[6:36] <ShorTie> my Arduino-1.6.0 patch is all over the web, lol.
[6:36] <puff> I mean, obviously there are going to be some hardware-specific aspects of sensors, but how much does that come into play in practice?
[6:36] <puff> Is there a catalog anywhere of sensors available?
[6:36] <seitensei> puff: All the temperature sensors I've worked with are analog
[6:36] <seitensei> :x
[6:36] <ShorTie> ebay
[6:37] <puff> I'm guessing that analog stuff, the limitations of the main board, or whatever you call the pi or beaglebone or arduino at the heart of it all, are going to be a big issue.
[6:37] <seitensei> you can convert the analog into digital with some extra hardware of course
[6:38] <puff> Off the cuff, any guess what a comfortable budget for this sort of thing might be?
[6:38] <clever> puff: the pi also has some trouble with high speed or high accuracy digital things
[6:38] <ShorTie> 100 bucks
[6:38] <seitensei> puff: well, arduino and beaglebone has both digital and analog, pi only has digital
[6:38] <clever> other apps can get in the way and slow it down slightly at the wrong time
[6:38] <puff> I mean, obvious if I came in and said I wanted to build it for $10, no way, for $10,000, clearly possible. I'd like to narrow that estimate a little :-)
[6:39] <seitensei> Beaglebone also has PRUs owo
[6:39] <ShorTie> 100 bucks
[6:39] <puff> ShorTie: Thanks.
[6:39] <ShorTie> that includes the pi and everything
[6:40] <puff> seitensei, clever, ShorTie, ali1234, thanks.
[6:40] <clever> puff: ah, i see your question now, ambient temperature sensors can be purely digital, meat-probe not sure, air flow, smoke density, humidity come in both analog and digital forms
[6:40] <ShorTie> sensors are cheap, couple dollars
[6:40] * mELs (~mls@ has joined #raspberrypi
[6:40] <clever> puff: a relay board would let you control things like fans and shutters to help regulate the heating
[6:41] <puff> clever: That might be cool to do, too. Mainly I'm interested in measuring... I want to improve the feedback loop.
[6:41] <clever> an ardruino could probly do it, but a pi would also let you program everything without a desktop/laptop, and you could drive a monitor to show how its running
[6:41] <puff> clever: That's what I'm leaning towards... How are the power requirements?
[6:41] <clever> any 2amp cellphone charger can run the pi
[6:41] <puff> clever: Is this definitely a wall outlet sorta thing, or is it conceivable to run it off batteries?
[6:42] <clever> it could run on batteries for maybe an hour or 2, depends on the battery size too
[6:42] <ali1234> from a car battery it would run for days

[6:42] <clever> car battery plus 2amp car phone charger
[6:42] <clever> done
[6:42] <puff> When you say high speed / high accuracy, what kind of speed are we talking about? 1 reading/second, 10 readings/second, 1 reading/10 seconds?
[6:43] <clever> in the 10,000 per second area it starts to have trouble
[6:43] <clever> 100 per second, no problems at all
[6:43] <jamesd> any guesses for a version 1 b+ on a 1000mva recharge device...
[6:43] <jamesd> monitor curcuit disabled.
[6:43] <puff> Heh... 100 second should be way more than enough.

[6:43] <puff> Thanks guys.
[6:43] <clever> puff: https://www.youtube.com/watch?v=Z2B67hybdAA a random example of relays on a raspberry pi
[6:43] <puff> Cool.
[6:44] <clever> puff: each relay could go to something like a fan, or a motorized shutter
[6:44] <clever> to help control the smoke pit
[6:44] <puff> Sweet.
[6:44] <clever> i'm guessing you would regulate it by adjusting the intake air?
[6:45] <ShorTie> pi with monitor https://www.dropbox.com/s/kpe5ek17e7e4fkf/IMAG0003.JPG?dl=0
[6:45] <puff> clever: Yeah.
[6:45] <clever> ShorTie: nice
[6:45] <clever> puff: and if you grab a display like ShorTie has, you can easily show the sensor levels and graphs
[6:45] <puff> clever, ShorTie: Cool.
[6:46] <clever> but anything with composite or HDMI can be done in minutes
[6:46] <clever> so an old tv or desktop monitor can be used as well
[6:46] <puff> How many outs/ins does a raspberry pi have?
[6:46] * invinceable (~invinceab@50-90-45-63.res.bhn.net) Quit ()
[6:46] <ShorTie> it's my movie camera, lol.
[6:47] <clever> puff: about 17 GPIO on the model a/b, a lot more on the pi2 or b+
[6:47] <clever> each can be input or output
[6:48] <puff> Cool.
[6:48] <ICantCook> I tend to run my openelec rPI on a .5a powerboard usb port with a usb cable. 24/7, used daily.
[6:48] <ICantCook> should I be getting a better psu?
[6:48] <seitensei> puff: there are 26 gpio on rpi
[6:48] <seitensei> b+/a+
[6:48] * methuzla (~methuzla@dsl254-017-117.sea1.dsl.speakeasy.net) has left #raspberrypi

[6:48] <puff> What a doof: http://www.zdnet.com/article/raspberry-pi-how-i-spent-almost-150-on-a-35-computer/
[6:48] <clever> puff: for ambiend air temp, and anything under ~100c, i would go with something like https://www.sparkfun.com/products/11050
[6:48] <puff> clever: cool.
[6:48] <clever> this is a digital temp sensor with a bus protocol, so you can run 100's of these on a single pin
[6:48] <clever> if you wanted to
[6:48] <seitensei> import to note that your PWMs are also tied into the audio system
[6:49] * mELs (~mls@ Quit (Quit: 离开)
[6:49] <puff> PWMs?
[6:49] <puff> pulse width modulation?
[6:49] <seitensei> yup
[6:49] <ShorTie> hehe, i can make a mini-raspbian image on the pi (B) and write to sdcard in like 34 minutes
[6:49] <clever> puff: the one i linked has a rubber cover, so its safe to just leave out in the open
[6:49] <clever> but the rubber may melt inside the oven area
[6:49] <seitensei> pi has 2 of them on gpio, but they're used for audio (if you don't need audio, works out)
[6:50] <seitensei> might be useful for audible alerts though
[6:50] <clever> puff: this second sensor, https://www.sparkfun.com/products/245
[6:50] <clever> no rubber, its good for up to +125c
[6:50] <clever> that one wont melt, but i dont know how hot your oven will get
[6:51] <puff> Probably around 200-300.
[6:51] <clever> https://www.sparkfun.com/products/251 this temp sensor is good for up to +482c
[6:51] <puff> mostly in the 250-275 range, for smoking.
[6:51] <clever> but you need some extra parts to read it
[6:51] <puff> Though I wouldn't mind something capable of higher temps, for experimenting.
[6:51] <clever> https://www.sparkfun.com/products/12871 and i just stumbled upon this, it looks like a meet probe, max of 135c
[6:51] * Chibby (~Chib@unaffiliated/chib) Quit (Quit: leaving)
[6:52] <puff> There's one approach where you run the oven at 500 degrees at first, then shut it off and let residual heat do the rest over several hours.
[6:52] <clever> i think its meant for scientific stuff and chemicals, but it might be food safe as well
[6:52] <puff> Cool.
[6:52] * RaptorJesus (~RaptorJes@unaffiliated/raptorjesus) has joined #raspberrypi
[6:53] <clever> the 482c limit on the type-k thermocouple sounds close enough
[6:53] <clever> oh wait, i didnt read it closely
[6:53] <ShorTie> you can get ds18b20's with like a 6' cord off ebay
[6:53] <clever> the glass cover is rated for 482c
[6:53] <clever> the sensor itself, is good to +1372c ....
[6:53] <puff> Yeah, but that's 900F. I think that's high enough :-)
[6:54] <clever> ah, your talking in f?
[6:54] <puff> Yeah, I'm an amurrrican.
[6:54] <clever> 500f is well within the safe range for the glass
[6:54] <clever> canadian here
[6:54] <puff> Cool.
[6:54] <clever> i find it crazy that your temp system is based on the core temp of a horse :P
[6:54] <puff> I've been to canada a few times :-).
[6:55] * oldtopman (~oldtopman@unaffiliated/oldtopman) Quit (Quit: *pouf*)

[6:55] <clever> https://www.sparkfun.com/products/307
[6:55] <clever> puff: a randomly selected thermocouple probe, digital interface
[6:55] <clever> so you can just wire the probe and this chip to the pi, at the cost of 2 GPIO pins
[6:56] <clever> and you now have the ability to read up to 900f
[6:56] <puff> Cool.
[6:56] <puff> I am taking notes here...
[6:56] <clever> the meat probe is also a thermocouple, https://www.sparkfun.com/products/12871
[6:56] <clever> and with a few chip select pins, you can run several at once
[6:57] <clever> ah wait no, its a thermistor, different type
[6:57] <clever> needs a different chip to read
[6:57] <puff> What little I know about thermistors is that the ones we used on our 3d printer are really annoyingly fragile.
[6:57] * qubitnerd (~neutrino@unaffiliated/electron/x-8286743) has joined #raspberrypi
[6:57] <clever> thats probly because the parts are naked
[6:58] <clever> once its mounted in a big plastic handle with a metal spike, it should be fine
[6:58] <phire> my one thinks my body is only 35�c
[6:58] <puff> clever: Yeah... the thermistors in question were on the "hot end" for the printer.
[6:58] <clever> some of the sensors may also need calibration
[6:59] * SebSemmi (~SebSemmi@p5483497A.dip0.t-ipconnect.de) has joined #raspberrypi
[6:59] <clever> the ds18b20 sensors claim to be accurate to 0.5 degrees over the -10 to +85c range
[6:59] <phire> it also thinks my freezer varies between 0� and -3�c
[6:59] <clever> puff: http://ext.earthtools.ca/export/temps_59.html
[6:59] <clever> this is an example of what you can do with ds18b20's
[6:59] <phire> I already know my freezer is broken and not cold enough, but... the water is frozen
[7:00] <clever> every room in the house, graphed, on one page
[7:00] <clever> http://ext.earthtools.ca/export/graph_54.html
[7:00] <clever> i turned the heat up at ~20:00 today
[7:00] <clever> you can see it coming on&off, holding the room within half a degree
[7:00] <puff> clever: I've thought about cobbling together my own zoned heating system...
[7:00] <puff> I wonder if I can get a barometric pressure sensor... probably.
[7:01] <clever> the house already has 3 zones, but crappy programable thermostats
[7:01] <clever> https://www.sparkfun.com/products/11823
[7:01] <clever> $5 barometer
[7:01] <phire> you can see the aliasing
[7:01] <clever> i2c interfacing
[7:01] <puff> cool.
[7:01] * qubitnerd (~neutrino@unaffiliated/electron/x-8286743) Quit (Client Quit)
[7:01] <clever> the pi has i2c, so at the cost of 2 pins, you can now read presure
[7:01] <phire> but I'm not going to complain about 0.1degrees
[7:02] * libc (~evany@pool-71-161-209-45.burl.east.myfairpoint.net) has left #raspberrypi
[7:02] <puff> Cool, I might build that separately.
[7:02] <jamesd> -
[7:02] <clever> for my heating system, i started by stringing plain old telephone cable everywhere
[7:02] <clever> one central line down the middle of the house, and then branching off of it to each room
[7:02] <clever> then i just randomly soldered ds18b20's on the ends, everywhere
[7:03] <puff> Hm.
[7:03] <clever> do i have any pics laying arround...
[7:03] <puff> So they all share the same wire? neat.
[7:03] * D-Boy (~D-Boy@unaffiliated/cain) Quit (Excess Flood)
[7:03] <clever> yep, bus protocol
[7:03] <puff> I've wanted to do something like that for complicated LED lighting ideas.
[7:03] <puff> I have an artist friend who does crazy stuff like that.

[7:05] <puff> That's more complicated than it looks. Not pre-recorded (well, obviously this video is prerecorded), the lights and sounds evolve over time based on a cellular automata setup.
[7:05] <clever> this is the living room temp sensor
[7:05] * Megaf (~Megaf@unaffiliated/megaf) has joined #raspberrypi
[7:05] <clever> i just used a piece of velcro to tie it to the back of a speaker
[7:05] <clever> there are sensors hidden all over the house like that
[7:05] <puff> Hm.
[7:05] <puff> clever: I might try something like that.
[7:05] <clever> everything runs back to an AVR chip in the furnace room, which reads the sensors every few seconds
[7:06] <clever> some solid state relays then switch the heating zones on/off
[7:06] <puff> clever: At least experiment with it a bit in terms of measuring, though my house is'nt set up for zones.
[7:06] <clever> and for added fun, the avr reports the temps out a serial port
[7:06] <clever> and a desktop does those graphs
[7:06] <puff> cool.
[7:06] <clever> then, for even more fun, a custom android app connects to the desktop
[7:06] <clever> and can display the current temp, and change the set points
[7:07] <clever> so i can turn the heat up from any android device
[7:07] <puff> Sweet.
[7:07] <puff> My house is all 3-course brick, which hugely affects heating/cooling and is a pain in the ass.
[7:07] <clever> screenshot incoming!
[7:07] <puff> I like brick, but.
[7:07] <clever> https://www.dropbox.com/s/pu8axofn1sg7di7/2015-02-10%2002.07.27.png?dl=0
[7:07] <puff> clever: Nice!
[7:08] <clever> i can set it to within 1/16th of a degree
[7:08] <clever> and its currently set to keep it within half a degree of what i set it to
[7:08] <clever> so the heat comes on at 21.00 and off at 21.50
[7:08] <puff> Thanks for the advice, I'm going to go off and do some reading now.
[7:08] <clever> which you can then see on http://ext.earthtools.ca/export/graph_54.html
[7:08] * Megaf_ (~Megaf@unaffiliated/megaf) Quit (Ping timeout: 245 seconds)
[7:08] <clever> if it gets even 1 pixel below 21.00, it locks on
[7:08] <clever> and remains on until 21.50
[7:08] <puff> clever: I think your graphs autoscaling is throwing me.
[7:09] * D-Boy (~D-Boy@unaffiliated/cain) has joined #raspberrypi
[7:09] <clever> C
[7:09] <clever> yeah, i set it to zoom massively
[7:09] <clever> the graph goes from 21.0 to 21.6
[7:09] <clever> you cant see the code doing its job when 0 is kept in view
[7:09] <puff> I'd like to track furnace activity, myself.
[7:09] <mortal> I may get pi2 today :)))
[7:09] <puff> My "house" is actually a large house that was converted into apartments.
[7:09] <clever> puff: i also record the total on time, let me see
[7:09] <puff> So I have four furnaces to keep track of.
[7:10] <puff> So I guess, in a sense, I *do* have zoned heating :-).
[7:10] <puff> But our gas costs last month for $500+.
[7:10] <clever> puff: http://pastebin.com/7bv7zzAX
[7:10] <clever> a chunk of my log file
[7:10] <clever> i could add timestamps, and get a record of how long the furnace is running, for every hour in a day
[7:11] * mike_t (~mike@ has joined #raspberrypi
[7:11] <puff> Yeah, I'd like to rig up something like that, and maybe something that does some obvious predicting/calculating.
[7:11] <clever> then see which hour is costing me the most, check the graph and set points
[7:11] <clever> and know who to blame
[7:11] <clever> atleast, that was my plan
[7:11] <clever> but 2 zones are uncontrolled
[7:11] <puff> so it can warn me, "hey, the furnaces are running a lot, gas bill is going to be high!"
[7:11] <clever> and with the stairs wide open, the basement heat rises up
[7:11] <clever> and the living room NEVER comes on
[7:11] * genbattle (~genbattle@122-59-87-87.jetstream.xtra.co.nz) has joined #raspberrypi
[7:11] <puff> Yeah, that's a pain.
[7:11] <clever> and the living room is the only one monitored
[7:11] <clever> so my logs say the heat never comes on
[7:12] <puff> I was thinknig about knocking out the floor/ceiling of one part of the ground floor, make a sort of great room or something.
[7:12] <puff> But the heating implications...

[7:12] * abnormal (~abnormal@85.sub-70-209-134.myvzw.com) Quit (Quit: Leaving)
[7:12] <clever> this would be 3 rooms in the basement
[7:12] <clever> the heat is coming on twice an hour
[7:12] <clever> it just keeps pouring up the stairs, and thru the barely insulated walls
[7:12] <puff> Basements, you also lose a lot of heat to the ground.
[7:13] <clever> ive opened a few walls, no vapor barrier
[7:13] <puff> You also have to watch out, did you seal the bottoms of the walls?>
[7:13] <clever> no vapor barrier at all
[7:13] <puff> I.e. the gap between the studs is like a duct. And you have them all around the perimeter of your foundation wall.
[7:13] <phire> oh cool, you can see summer
[7:13] <clever> the basement was finished when we bought the house
[7:13] <puff> Hm... might be worth looking into that.
[7:13] <clever> phire: yep
[7:14] <clever> it rose up over +30c in the server room
[7:14] <clever> when i had ~5 computers in there
[7:14] <phire> the bedroom is on the south (north) side of the house?
[7:14] <clever> i have since had several leaky caps kill off a few
[7:14] <puff> clever: FWIW, there's a lot of BS out there. Greenbuildingadvisor.com and "building science 101" seem semi-decent, in terms of scientific validity.
[7:14] <clever> phire: east side
[7:14] <clever> bedroom is east, hallway is central, server is west
[7:15] <clever> hmmm bedroom is more of the north east corner, but it only has an east facing window, with 'shade' (another house) blocking everything out :P
[7:15] <puff> clever, seitensei, ShorTie, ali1234: I have to go AFK now, thanks again, very much, for the advice.

[7:16] <clever> so i can see if anything corelates between them
[7:16] <clever> but the kitchen sensor happens to be under the microwave

[7:24] <clever> https://github.com/cleverca22/crosspiroot
[7:24] <clever> jascase901: its not the best option, but these scripts let you chroot into a pi .img
[7:24] <clever> its a mix between full emulation and normal chroot
[7:25] <clever> as far as the compiler tools are concerned, they are running on an armv6, and are doing a normal armv6 build
[7:25] <jascase901> This seems really interesting
[7:25] <jascase901> Thanks
[7:25] <clever> it uses your existing kernel, so you get all your cores and ram
[7:26] <jascase901> What makes it not the best option?
[7:26] <phire> build speed is not as fast as a native compiler
[7:26] <clever> and its using qemu like a script interperter, to emulate the userland and translate all syscalls
[7:26] <clever> jascase901: what phire said, it chews a ton more cpu power
[7:26] * nullfaith (~nullfaith@2605:6000:1023:c05c:1181:e4a7:9fb7:70f) Quit (Ping timeout: 245 seconds)
[7:26] <phire> and I don't think qemu is the fastest jit in the world
[7:26] <clever> you get to use all your cores, so you could emulate an 8 core armv6, but each core is slower then if you did a proper cross-compile
[7:27] <phire> (it is a jit, right?)
[7:27] <jascase901> Ill give it a shot. Right now it takes an entire day to compile opencv on the pi.
[7:27] <clever> i thought it was just a switch-case on each opcode?
[7:27] <clever> jascase901: to update it for your system, youll have to find the right offsets in the start file, run fdisk -l on the .img
[7:27] <clever> and fix the .img name
[7:28] <clever> and install qemu-user-static for armv6

[7:33] <clever> oh, the start script can be fixed to not need offsets anymore
[7:34] <clever> jascase901: if you use losetup with -P, then the partition will just obey the partition table, and it works right

[9:16] <Xark> Lartza: I am quite curious of why Sonic Pi "cares". Is it not all userspace...?
[9:16] <Lartza> Me neither, so why is Sonic Pi given so high priority over kernel...
[9:16] <Xark> Lartza: You have seen forum thread? Because it was used in education.
[9:16] <Lartza> That too but mainly why is it the responsibility of the kernel to "work" instead of fixing a broken program
[9:16] <Lartza> Mhh
[9:16] <Xark> They hope to have Sonic Pi fixed "soon" then restore the split.

[9:18] <Lartza> I never use rpi-update
[9:18] <Lartza> for anything

[9:19] <Lartza> but that causes the Pi to freeze/crash with a keyboard...
[9:22] <Lartza> Oh Raspbian ships with Sonic Pi too so that's probably why the split is kept...

[9:47] <Lausi> Aaah. Gotcha.
[9:48] <Triffid_Hunter> Lausi: however most OS tasks are random write, and cards optimized for high sequential write tend to be poor at random wrote
[9:48] <Triffid_Hunter> write*
[9:48] <RaTTuS|BIG> good class 4 / 6 are much better for small rw access ...
[9:48] <RaTTuS|BIG> ^WHS

[11:03] <kushal> but the same is not working on rpi2 with 2015-01-31 raspbian image, wlan0 device can not be found.
[11:03] <kushal> Any help/tipis?
[11:03] <kushal> * tips
[11:04] <shiftplusone> figure out which module it needs, check if it's enabled in both kernel configs, if not, request that they add it.
[11:05] * kd7jwc (~nonyabusi@75-164-173-98.ptld.qwest.net) has joined #raspberrypi
[11:05] <kushal> shiftplusone, it should be enabled from 3.6.11+ kernels as mentioned in http://elinux.org/RPi_USB_Wi-Fi_Adapters
[11:06] * ValicekB (~tbox@dot.snat.baz.cz) Quit (Read error: Connection reset by peer)
[11:07] <shiftplusone> that doesn't really have anything to do with the suggestion though
[11:07] * kcj (~kcj@unaffiliated/kcj) Quit (Remote host closed the connection)
[11:07] <kushal> shiftplusone, true.
[11:09] <shiftplusone> What I was getting at is that it might not be in 3.18 for whatever reason (maybe they forgot to enable it). The fact that a random page on the internet says something else is not relevant. Even if it it enabled, and you want to troubleshoot it, the first step is still to figure out what module it is.
[11:09] * qubitnerd (~neutrino@unaffiliated/electron/x-8286743) has joined #raspberrypi
[11:09] <kushal> shiftplusone, yup, I can see 3.18 has lot of less modules loaded.

[11:40] <shiftplusone> and simply having a higher clock rate and dedicated gbit ethernet doesn't make the C1 better. It lacks in many areas when compared to the pi. Well, maybe not many, but it's very naive to go by the CPU specs alone.
[11:40] <day> shiftplusone: i mean, cpu power is welcome. Both have >4times than i am using right now :D
[11:41] * RaTTuS|BIG uses a Tonido Plug 2 for file server , adn the RPI for everythign else - 100mbps is fine for most things - the CPU is never stressed [samba run fine on it for most things]
[11:41] <day> the more the merrier
[11:43] <shiftplusone> day, in your case, maybe one of the higher end odroids might be better.

[17:21] <shiftplusone> Hix, if you're keen on diving in further, I recommend playing around with Arch on PC (perhaps in a VM) a bit.
[17:22] <Hix> I can certainly try Arch on a VM on my macbook. Is there a reason for using Arch over Debian?

[17:25] <shiftplusone> When you install Debian, you install a lot of things you didn't ask for, including tools which abstract away some common tasks. When you install Arch you get a starting point, so in the process of setting things up, you learn the things that Debian does behind the scenes.
[17:26] <omfgtora> hmmm... arch is based on debian?
[17:26] <ali1234> no
[17:27] <ali1234> arch is nothing at all like debian

[17:53] <shiftplusone> anunnaki, take the pi, find the little notch indicating pin 1, rotate it so that it's in the top left corner, count from left to right, top to bottom (like you would read). That's applicable to everything, not just the pi.

[23:31] <ali1234> i suspect they just didn't want people running it on non-intel hardware
[23:31] <l_r> gcc can certainly benefit from NEON presence
[23:32] <leio> I mean can't the compiler make use of the instructions and registers to speed things up, compared to not doing so, while optimizing pure C code
[23:32] <PovAddict> if you want armv7, use debian armhf instead of raspbian
[23:32] <shiftplusone> I don't know if it's down to NEON or not, but even now GCC is insanely faster on the pi 2 than a pi 1.... more than the clock rate and number of cores can account for.
[23:32] <leio> I mean, SSE4 or whatever is sure fringe stuff, but NEON is basics too, like iwMMXt
[23:32] <l_r> PovAddict, have you tried debian on the rpi2?
[23:32] <ali1234> leio: yes it can, but it often won't
[23:33] <ali1234> compilers are smart and getting smarter all the time
[23:33] <shiftplusone> But yes, people are claiming that armv6 packages should already support NEON, unless plugwash has compiled them specifically with that feature disabled.
[23:33] <leio> I'm happy if it won't if that means it's actually not slowing things down in certain cases :P
[23:33] <shiftplusone> So I've been trying to catch him for questions on IRC.
[23:33] <leio> said people must have packages in mind which ship separate binaries for the tuned assembly that can be runtime picked
[23:34] <l_r> did anybody test debian armhf on the rpi?
[23:34] <l_r> rpi2
[23:34] <leio> meanwhile I'll be happy with audio decoding, pixman, pulseaudio and gstreamer making use of NEON :)
[23:34] <leio> and just take the rest as a bonus I suppose
[23:34] <shiftplusone> l_r, yes.
[23:35] <l_r> leio, that certainly means a new image
[23:35] <leio> note, this is not #raspbian
[23:35] * abnormal (~abnormal@219.sub-70-209-142.myvzw.com) has joined #raspberrypi
[23:35] <ali1234> shiftplusone: i bet multiarch could be abused for this purpose
[23:35] <phire> So, if I want a good buildroot repo for rpi?
[23:35] <l_r> shiftplusone, have you found any problems with debian?
[23:36] <shiftplusone> ali1234, I had a brief look at multiarch, but haven't tried to use it like this.
[23:36] <phire> this one? https://github.com/gamaral/rpi-buildroot/tree/rpi
[23:36] <PovAddict> l_r: I don't have a rpi2
[23:36] <ali1234> phire: how about openwrt?
[23:36] <shiftplusone> l_r, yeah, memory bandwidth is significantly less and the fbturbo driver doesn't install.
[23:36] <l_r> :(
[23:36] <phire> ali1234, what do you use?
[23:37] <ali1234> phire: raspbian - i only got my pi last week
[23:37] <shiftplusone> l_r, but if you want to use ffmpeg/libav or something similar it's about twice as fast in debian than it currently is in raspbian.
[23:37] <l_r> debian is too much important in the linux ecosystem...i think they should support it
[23:37] <ali1234> but i am looking for something that can give me a readonly rootfs with ramfs overlay like the old style openwrt did
[23:37] * libc (~evany@pool-71-161-209-45.burl.east.myfairpoint.net) has joined #raspberrypi

[23:37] <phire> raspbian will get you quite far

[23:38] <phire> I've been putting off doing a buildroot for ages
[23:40] * wheelsucker (~wheelsuck@ Quit (Quit: Client Quit)
[23:41] <shiftplusone> phire, what do you want to use it for?
[23:41] <phire> embedded system
[23:41] * megaproxy (~hillbilly@unaffiliated/megaproxy) Quit (Quit: WeeChat 0.3.7)
[23:41] <shiftplusone> judging by the vagueness, it's for work?
[23:41] <ali1234> phire: do you still have those s1mp3 players deployed? gonna replace them with raspberry pis?
[23:42] <phire> raspbian is built on the assumption that it will be running on a read/write system
[23:42] <phire> shiftplusone, yeah work
[23:42] <phire> ali1234, those s1mp3 players were fragile
[23:42] <ali1234> yeah true that
[23:43] <phire> so there is a openwrt port
[23:43] <ali1234> yeah, that's why i mentioned it :)
[23:43] <l_r> there is an android port to...
[23:43] <leio> phire: build gentoo binpkgs and roll it together from there? :)
[23:43] <phire> soft-float only
[23:43] <l_r> but it s not going to see the light
[23:43] <shiftplusone> ah, fair enough. There's likely to be a raspberry pi 2 defonfig popping up in buildroot upstream soon, but it's very obvious how to get there from the pi 1 defconfig.
[23:43] <phire> buildroot is probally the best idea
[23:44] <ali1234> openwrt is very very similar to buildroot so....
[23:44] <phire> buildroot does readonly roots too
[23:44] <ali1234> okay
[23:44] <phire> (I mean I can pratically roll one in my sleep, given enough time)
[23:45] <phire> so there is rpi support in buildroot upsteam?
[23:46] <shiftplusone> yeah

[23:47] <shiftplusone> and we use it quite a bit... the test system, NOOBS and a few other things. I like it for driver development since it reboots quick if (when) I lock things up. >.>

[23:50] <phire> not quite
[23:50] <shiftplusone> /etc/inittab -> ourthing?
[23:51] <phire> yeah
[23:51] <phire> a few other things get started, like gpsd
[23:51] <shiftplusone> ah
[23:51] <phire> networking (mostly for debugging)
[23:52] <shiftplusone> Hmm... eye twitching. =S
[23:52] * shiftplusone checks if someone posted something stupid on the forum.
[23:52] <shiftplusone> nope, false alarm.

[23:59] <phire> lets start with a crosstools-ng toolchain
[23:59] <phire> otherwise buildroot continually rebuilds one
