[0:00] <wcarson> [Saint]: yeah, i got an immediate e-mail with a link to download a pdf, but the pdf is what says it's not my actual key and the real thing will be emailed in up to 72 hours
[0:01] <grandpa> https://play.spotify.com/track/2smax1OWAxOo63p14G8KZx
[0:04] * zoktar (~zoktar@unaffiliated/zoktar) has joined #raspberrypi
[0:06] <[Saint]> thank the lord for scp.
[0:06] <[Saint]> I messed up a local network wide deployment of a ~/.screenrc file with rsync
[0:07] <[Saint]> A stypid typo. "SHELL=/bin/bsah"
[0:08] * duckpuppy (~patrickai@ has joined #raspberrypi
[0:08] * Uber (~UberSMPL@unaffiliated/ubersmpl) Quit (Quit: -=I'm Gone=-)
[0:08] * Wurst (~Wurst@ Quit (Quit: -=I'm Gone=-)
[0:09] * monorail0 (b8582d7d@gateway/web/freenode/ip. has joined #raspberrypi
[0:10] <[Saint]> so I just did 'touch .screenrc ; scp .screenrc $user@local.machines:/destination' to test out if it was indeed my reasonably recent modification to ~/.screenrc, and then sure enough ssh/screen started responding predictably again, so I sent the correct version out en masse via rsync.
[0:11] * Wurst (~Wurst@ has joined #raspberrypi
[0:11] * UberSMPL (~UberSMPL@unaffiliated/ubersmpl) has joined #raspberrypi
[0:11] * UberSMPL is now known as Uber
[0:12] * zoktar (~zoktar@unaffiliated/zoktar) Quit (Ping timeout: 240 seconds)
[0:12] * hydrogen (~hydrogen@amarok/developer/hydrogen) has joined #raspberrypi
[0:13] <[Saint]> vrmxm: the final reason I'm looking at being able to do this in a very minimal footprint and looking to provide as much of the system itself as I can with busybox and a stripped down Debian base is I am looking at allowing for PXE boot in the long term future of the project.
[0:15] * Wurst (~Wurst@ Quit (Client Quit)
[0:15] * Uber (~UberSMPL@unaffiliated/ubersmpl) Quit (Client Quit)
[0:15] <[Saint]> My basic idea is allowing for a platform where users can buy a raspberry pi 3, and a decent USB power supply, and a very small and inexpensive sdcard and write in a supplied boot image (that should fit in well under 512MB) to provide early boot and set up PXE boot.
[0:16] * UberSMPL (~UberSMPL@unaffiliated/ubersmpl) has joined #raspberrypi
[0:16] * jakent (~john@ has left #raspberrypi
[0:16] * UberSMPL is now known as Uber
[0:17] * TheSin (~TheSin@gateway.bluefalls.ca) has joined #raspberrypi
[0:18] * Wurst (~Wurst@ has joined #raspberrypi
[0:19] <[Saint]> A couple of wrapper scripts from ~/bin providing the functions for the crontab a single setup.sh script to deploy the whole thing.
[0:20] <[Saint]> If the user uses a raspberry pi 3, and a 4~5A 5V PSU, they can have all four USB ports on the board supplying different USB webcams (as long as their consumption is in the 600mA~800mA range).
[0:21] * Palsson (~Palsson@c-0f06e655.06-213-6e6b701.cust.bredbandsbolaget.se) has joined #raspberrypi
[0:21] <[Saint]> The magic is there to detect and make a composite image out of up to four USB webcams.
[0:21] <[Saint]> Oddly I haven't actually looked in to supporting the Pi Camera yet.
[0:22] <vrmxm> I'll make sure to contract you when I need a setup for my low budged indie adult film studio
[0:22] * sdothum (~sdothum@ Quit (Quit: ZNC - 1.6.0 - http://znc.in)
[0:22] <[Saint]> I doubt it would be too much work to add support for the Pi Camera.
[0:22] <[Saint]> But I figured that, like me, a lot of people are going to have some form of USB webcam available.
[0:23] <vrmxm> I thought most webcams came built-in nowadays?
[0:23] <[Saint]> and may or may not have or want the expense of the dedicated camera module.
[0:23] <[Saint]> vrmxm: yes and no, I mean they do - but external webcams are definitely still a thing.
[0:24] <[Saint]> You can get USB 1080p clip on webcames for like $15
[0:24] <[Saint]> *webcams
[0:24] <vrmxm> Huh
[0:25] <[Saint]> For the same price as the Pi Camera you could double or triple the amount of cameras you could supply with USB webcams.
[0:25] <[Saint]> My reasoning there is supporting the cheapest possible avenue.
[0:25] <[Saint]> it isn't for live streaming, though I may add that ability in in the end.
[0:27] * TunaLobster (~TunaLobst@ has joined #raspberrypi
[0:27] <[Saint]> It is taking a frame every 30s and comparing that with the neighboring frames to check for significant difference and marking them as 'interesting' images to stitch a timelapse .gif together.
[0:27] <[Saint]> the way I do the comparison/diffing is pretty convoluted but it works well and is surprisingly fast.
[0:28] <vrmxm> So, nannycam?
[0:29] <Wurst> [Saint]; is this suppose to be something special?
[0:29] <Wurst> Using a WebCam on a Pi is nothing new
[0:30] <[Saint]> Hey, way to be a dickbag, Cpt. Grumpypants. You're awesome.
[0:31] <[Saint]> And I'm fully aware the concept is nothing new. What is arguably novel is a simply means to deploy such a system with a single setup script and have it 'just work' for end users.
[0:31] <Wurst> It was just a question... after reading your Essay on what you're doing, I didn't see anything that hasn't been done already
[0:31] <[Saint]> I don't feel as though everyone who wants to do this in a simple fashion with zero configuration should need to reinvent the wheel every time.
[0:32] <Wurst> FSWEBCAM allows for control over a USB webcam
[0:32] <[Saint]> If you did read as you said you did you would be fully aware of the fact that I am using fswebcam.
[0:33] <[Saint]> WHy not try being productive instead of taking shots at people who are being productive?
[0:33] <Wurst> lol; you are overly defensive... I asked what was special about your project, to understand what I missed
[0:33] <Wurst> You need a chill pill, or to get laid or something
[0:34] <Berg> donald trump has chill pills for hillary
[0:34] <Berg> hello world i wake i see i drink coffee
[0:35] <Wurst> @berg don't we all
[0:36] <Wurst> coffe addition >= crack addition
[0:36] <Berg> less than equal too?
[0:37] <Berg> im actualy addicted to electrons
[0:37] <Wurst> less than would be <
[0:37] <Berg> i need to store them im an electron hoarder
[0:37] <Berg> yeah i always get them wrong
[0:38] <Wurst> crocodile eats the larger number ;)
[0:38] <Berg> so coffee is less gooder addiction then craCK
[0:38] * zoktar (~zoktar@unaffiliated/zoktar) has joined #raspberrypi
[0:38] * duckpuppy (~patrickai@ Quit (Ping timeout: 260 seconds)
[0:38] <Wurst> coffee is a "gooder" or equal addition to crack
[0:39] * m1nus_ (~m1nus@ has joined #raspberrypi
[0:39] <Berg> you need a better way to express yourself
[0:39] <Wurst> a better way than ?
[0:39] <Berg> greater meaning a larger amount or greater meaning more gooder
[0:40] * m1nus (~m1nus@ Quit (Ping timeout: 250 seconds)
[0:41] <Berg> if coffee == true and happy == true:
[0:41] <Berg> ok im confuseed
[0:41] * [Saint] thinks someone using antiquated parlance like 'gooder' and 'more gooder' probably shouldn't throw stones around their glass house. ;)
[0:42] <Wurst> it's a gooder thing post people don't live in glass houses
[0:42] <Wurst> most*
[0:42] <[Saint]> you dun did worded that up plum goodly like.
[0:42] <Berg> still i have been making batteries from copper pipe epson salts and gtalanized bolts
[0:43] <[Saint]> yous'a some type'a word engineer?
[0:43] <Wurst> Berg; you sure "batteries" is the correct term, and not pipe bomb
[0:43] <Berg> i get 0.8v on average per cell
[0:44] <Berg> i might make a rail guun from the electrons
[0:44] <Wurst> sounds like a plan
[0:44] <Berg> i need a way to measure each cell voltage with a pi while having many cells in series
[0:45] * TheCubeLord (~darkness@unaffiliated/thecubelord) Quit (Ping timeout: 258 seconds)
[0:45] <Berg> maybe some form of module

[0:47] <Wurst> Umm, I think there is a project on GitHub for that
[0:47] <Wurst> like pivoltagecheck or picheckvoltage
[0:47] * Cy-Gor (~IceChat9@cpe-70-113-62-36.austin.res.rr.com) has joined #raspberrypi
[0:48] <Wurst> I think he/she uses combined voltage (from all cells) instead of monitoring each cell.
[0:48] <Wurst> but that could be a starting point
[0:49] * redsPL (~reds@ Quit (Quit: Leaving)
[0:49] * zoktar (~zoktar@unaffiliated/zoktar) Quit (Ping timeout: 250 seconds)
[0:49] <Valduare> setup multiple webcams, that look at specific gravity bulb gauges and rig up a solenoid to squeese the bulb on a timer and then analyse the image snapshot
[0:49] <Valduare> rigt this up for each cell you want to measure :)
[0:49] * secrgb (~secrgb@ Quit (Quit: -)
[0:50] <Berg> ok will look
[0:51] * m1nus_ (~m1nus@ Quit (Ping timeout: 276 seconds)
[0:51] <Berg> thats a bit overkill Valduare
[0:51] <Valduare> nahhh :)
[0:51] <Berg> and i am using a solid electolyter

[1:10] <Uber> Who would use a 32GB mSD card on a pi?
[1:11] <grandpa> crazy people
[1:11] <bluskys> What is wrong with a 32GB mSD on a rpi?
[1:11] <grandpa> its just cray cray
[1:12] <grandpa> :p
[1:12] <Uber> 1 being its overkill.
[1:12] <Valduare> not really
[1:12] * grandpa wiggles his 64gb, 32gb, etc microsd cards
[1:12] <bluskys> ? maybe they have a lota files to store?
[1:12] <grandpa> im using a 320gb hdd on my pi3
[1:12] <Valduare> now if you buy an 800 gig micro sd card from china for 4 bucks…. thats crazy :P
[1:12] <grandpa> :>
[1:12] <jKlaus> I also have a 4G sitting here next to me..
[1:13] <bluskys> I plan on using to host offline web files... ehehehee
[1:13] <jKlaus> about friggin time
[1:13] <jKlaus> this thing is finally done
[1:13] <Uber> Lots of files or not, just need a small mSD then us a USB thumbdrive to store files...
[1:13] <Valduare> Uber: not always
[1:13] <jKlaus> To me, there is nothing more annoying than running out of space lol
[1:13] <jKlaus> might as well over buy
[1:13] <Valduare> if your building retropie for 4 players
[1:13] <jKlaus> over buy and under use
[1:13] <Valduare> might as well throw your roms on the micro sd
[1:13] <grandpa> yea..you can use them in something else later on too
[1:14] <bluskys> i guess. of course if you want the lowest power usage .. 128Gb mSD would be wonderful....
[1:14] <jKlaus> I'm still trying to figure out what I'm going to use this pi for
[1:14] * bluskys giggles with glee
[1:14] <Valduare> jKlaus: setup berryboot and use the pi for many things :)
[1:14] <jKlaus> I've been considering using it run my prusa mendel
[1:14] <Uber> Valduare; that's no reason for a 32GB micro SD..
[1:14] <Valduare> how so Uber
[1:15] <bluskys> so is berryboot like a form of multi boot on pi?
[1:15] <jKlaus> What's wrong with having a huge SD?
[1:15] <jKlaus> I think grandpa's just upset b/c in his day they used floppy disks
[1:15] <Valduare> gives the onboard controller more surface to wear layer :)
[1:15] * bluskys hasn"t used berryboot before... anyone say obvious? lol
[1:15] <Uber> boot from the SD and run everything from a USB Flash.. so if the boot gets corrupt due to power lose, etc you are not replacing a 32GB micro sd, but a cheap $5 8GB
[1:15] <jKlaus> or w/e those big ol apple disks were called
[1:15] <Uber> Or store ROMS on a USB flash, so you can disconnect the drive without shutting down.
[1:16] <Uber> But everyone has their own boats to tugg.. so to each their own
[1:16] <bluskys> those 8" floppies were pretty!
[1:17] <bluskys> always wanted a cassette recorder for my TRS80 model 1
[1:17] <ShorTie> floppy disks are new, cassette tapes are where it's at
[1:17] <bluskys> lots of typing practice ... hehehe

[1:57] <Ahmed90> not decided yet
[1:57] <Ahmed90> looking for options
[1:57] <k_j> Ahmed90, 640x480 is enough?
[1:57] <Ahmed90> trying to build vehicles imaging/scaning gate
[1:57] <Ahmed90> little more
[1:58] <Ahmed90> no need for vids
[1:58] <Ahmed90> images only
[1:58] <Wurst> FSWEBCAM https://www.raspberrypi.org/documentation/usage/webcams/ ???
[1:58] <Ahmed90> vehicle views top, plate, driver face
[1:59] <Ahmed90> Wurst, can it handle 3 cams minimum ?
[2:00] <Wurst> i don't see why not

[2:05] * dreamon (~dreamon@unaffiliated/dreamon) Quit (Ping timeout: 265 seconds)
[2:05] <Ahmed90> afaik the raspi USB share the power and controller
[2:06] <Wurst> You mean like a powered USB Hub?
[2:06] <Ahmed90> or just a hub yeah
[2:06] * vdamewood (~vdamewood@unaffiliated/vdamewood) has joined #raspberrypi
[2:06] * k_j (~no@ has left #raspberrypi
[2:06] <Ahmed90> power gonna be limited on solar power D:
[2:08] <DWKnight> depends on the panel really
[2:08] <Ahmed90> its basically a dump in the middle of nowhere and need to install scanning/imaging on the gate
[2:08] * Yuki_ (~Dochi@2a02:a212:a180:c300:7d9f:b448:51b4:e371) Quit (Quit: Leaving)
[2:08] <Wurst> Add a Power Booster maybe? https://learn.adafruit.com/adafruit-powerboost-1000c-load-share-usb-charge-boost/overview
[2:09] <Ahmed90> DWKnight, yeah i know but trying cut the expenses
[2:09] <Ahmed90> Wurst, thats interesting
[2:10] * pepee- (~pepee@unaffiliated/pepee) has joined #raspberrypi

[2:11] * pepee- is now known as pepee
[2:12] <Wurst> 3 18650 batteries in parallel would last a couple days between charges
[2:13] <Ahmed90> with the booster?
[2:13] <Wurst> Yeah
[2:13] <Wurst> But with the Solar Panel charging - things would stay powered
[2:13] <Ahmed90> what about a power packs?
[2:14] <SpeedEvil> Ahmed90: it depends where you are.
[2:14] <Ahmed90> SpeedEvil Iraq :DDD
[2:14] <SpeedEvil> Ahmed90: To keep a pi going at 2.5W here - requires 250W of solar panel or so.
[2:14] <SpeedEvil> It may be rather sunnier there.
[2:14] <SpeedEvil> (in december)
[2:14] <Ahmed90> plenty of sun light
[2:14] <Ahmed90> even in winter
[2:14] <SpeedEvil> You're probably going to want ideally a 15+W panel, I suspect.
[2:14] <SpeedEvil> smaller may be OK
[2:15] <SpeedEvil> but not that much smaller - if you want it up 24*7
[2:15] <Wurst> Ahmed90; I use that booster in my Weather Station & Garden watering project and I've never had power failure.
[2:15] <Wurst> I replace the batteries about ever 3-4 months, just to make sure they are top notch
[2:16] <Ahmed90> SpeedEvil, i won't worry much about the power tbh the company electricians would deal with it
[2:16] <Ahmed90> am just putting the structure / doing the code
[2:16] <SpeedEvil> I've been using 'motion' - which may be pretty much what's needed.
[2:17] <SpeedEvil> It can do USB cameras, motion activated recording, region or mask triggering
[2:17] <SpeedEvil> http://www.lavrsen.dk/foswiki/bin/view/Motion/MotionGuide
[2:17] <Ahmed90> Wurst, cool i didn't know boosters exist D: had power issue with arduino a booster would have been great
[2:18] <Wurst> FSWEBCAM would work just fine, a small python script that runs "fswebcam -d /dev/video0 photo1.jpg" (/dev/video0 being the camera..)
[2:18] <Wurst> connected to a small PIR motion sensor to activate the script
[2:18] <Wurst> and your done
[2:18] <Ahmed90> Wurst, it will be activated by rfid scanner
[2:19] <Wurst> or that
[2:19] <Ahmed90> need to catch the img and send over to server
[2:19] <Wurst> FSWEBCAM allows for SSH/SCP
[2:19] <Wurst> and there are simple python modules for creating/sending email --
[2:20] <Ahmed90> was thinking of doing it with api / post request
[2:20] <Ahmed90> but scp would be cool.. (if the client allows me to delay a little)
[2:21] <Wurst> whatever works really, there's multiple ways to get the end results.
[2:21] <Ahmed90> yeah
[2:21] <Wurst> I'm just more of a Python guy so I tend to use it for everything

[2:26] <Ahmed90> i was thinking of a dvr to the raspi ethernet
[2:26] <Ahmed90> capture an img from the stream etc
[2:27] <Wurst> Umm, someone else would have to chime in on that one.. I'm not familiar with DVRs. Not sure what kinda access they would allow via Ethernet, or what ports they have for access
[2:27] * hydrogen (~hydrogen@amarok/developer/hydrogen) Quit (Remote host closed the connection)
[2:27] <Ahmed90> some dvrs have internet/live streaming options
[2:28] <Ahmed90> rtsp etc..
[2:28] <Wurst> If that's the case, then I'm not sure what role the RaspPi would play in it
[2:29] <Ahmed90> take an img of the cars on time, read the rfid, open the gate, send signal to the LED screen
[2:29] <Ahmed90> to tell the driver to move etc..
[2:30] <Ahmed90> and ofc send all these data to the server via usb modem
[2:30] <Ahmed90> cool story right :D
[2:30] <cassoPi> SURE
[2:30] <cassoPi> sure*
[2:30] <cassoPi> :)
[2:31] <Ahmed90> the boss of the company loved the pi lol ..
[2:31] <Ahmed90> he started to think of the pi first in any project xD
[2:32] <Wurst> Well you need a way for the Pi to access the feed from the DVR, and then take a snap shot from that feed...
[2:32] <Ahmed90> yeah thats what am researching atm
[2:33] * CuriousCat (~CuriousCa@unaffiliated/wye-naught/x-8734122) Quit (Ping timeout: 258 seconds)

[2:35] <Ahmed90> yeah.. am also thinking of using the pi camera modules
[2:35] <Ahmed90> not sure how reliable thy are but.. how to connect 3?
[2:36] <Wurst> as far as I know you can only connected 1 camera module to a single Pi
[2:36] <Ahmed90> yeah
[2:36] <IT_Sean> that is correct.
[2:36] <IT_Sean> mostly.
[2:36] <IT_Sean> The compute module supports two, i believe.
[2:37] <Ahmed90> hmm
[2:37] <SpeedEvil> https://flashair-developers.com/en/
[2:37] <SpeedEvil> as another alternative
[2:37] <SpeedEvil> this is a programmable SD card.
[2:37] <SpeedEvil> with wifi. It can even run lua scripts on boot
[2:38] <SpeedEvil> stick it in a trailcam, ...
[2:38] <Ahmed90> SpeedEvil, o.O
[2:39] <Ahmed90> how can i trigger a "take image" with this?
[2:39] <Wurst> IT_Sean; the compute module doesn't support 2 natively -- and adpater is required I thought
[2:39] <IT_Sean> well, you need some kind ofbreakout board anyway, as the compute module itself does not have any ports on it. That said, i _think_ both of the SoC's CSI connectors are broken out to the edge connector
[2:40] <IT_Sean> check me on that, though, as i've never done it.
[2:42] <Wurst> This would work http://www.newark.com/raspberry-pi/rpi-compute-dev-kit/raspberry-pi-compute-dev-board/dp/62X6560?MER=bn_level5_3NP_EngagementRec_1
[2:42] <Wurst> but limited to 2 CSI ports
[2:43] <Ahmed90> even tho the pi camera quality is better than the off the shelf cctv but don't think it would fit without hardware modifications :/
[2:44] <Wurst> not true; pi camera is not that great
[2:44] <Wurst> its what 8MP in the new one
[2:44] <Wurst> 5MP in the old one
[2:44] <binaryhermit> ahh yes, the mp myth
[2:44] <Ahmed90> its still better than cheap cctv cams which cost more
[2:44] <Wurst> Video is good at what 1080?
[2:45] <methuzla> full HD is only 2MP
[2:45] <Wurst> Maybe, but 2MP doesn't produce a low grain large res photo

[2:53] <Ahmed90> cars have rfid stickers
[2:53] <Ahmed90> scanner connected to the pi
[2:53] <methuzla> separate system? triggers cameras?
[2:53] <Wurst> isn't there a guard box next to the gate?
[2:53] <Ahmed90> yeah
[2:54] <Wurst> Which would be powered 24/7
[2:54] <Ahmed90> but hes not to be trusted :D
[2:54] <Ahmed90> depends
[2:54] <Wurst> so no need for solar power
[2:54] <Voop> radio frequency identifacation - RFID
[2:54] <Ahmed90> its iraq after all :P
[2:54] <methuzla> and sounds like no requirement for tight coupling on the image capture
[2:54] <Ahmed90> lol 13 years later we still dont have 24/7 power grid
[2:54] <Wurst> Well if the guard box isn't powered, it's a good bet the gate won't be either.. so no access either way
[2:55] <Ahmed90> guard is not trusted and gate can be open manually
[2:55] <methuzla> how far apart are the 3 camera located?

[3:20] <jmadero> anyone around running raspbian on an RPi first gen who is willing to do a quick test?
[3:20] <jmadero> I can't get mine to rotate for me at all and it's becoming frustrating
[3:23] <Wurst> Sorry mine got zapped a while back
[3:23] <jmadero> no need to apologize, just figured I'd jump in and ask - trying to use my Pi as a magic mirror but can't do that if I can't get it to rotate
[3:24] <ali1234> have you updated the software?
[3:24] <jmadero> yeah
[3:24] <jmadero> it very briefly rotates as it's booting up, then flickers and goes back to not rotated
[3:25] <jmadero> I'm disappointed to see so many distros deprecated, I'm willing to try another distro but the wiki basically says all are no longer supported
[3:25] <ali1234> why can't you just use raspbian?
[3:26] <ali1234> nothing much can run on the first generation pi because it is an old ARM architecture
[3:26] <ali1234> your only other options are debian armel or compiling something yourself
[3:26] <jmadero> I can - but it won't rotate for me
[3:26] <jmadero> which is what I need it to do
[3:27] <Wurst> jmadero; did you allocate more memory for the GPU ?
[3:27] <jmadero> yeah
[3:27] <Wurst> think the rotation requires extra GPU memory
[3:28] <jmadero> yeah I added as much as I could
[3:28] <ali1234> what options did you put in config.txt?
[3:28] <jmadero> display_rotate and gpu allocation to max functional
[3:28] <jmadero> or rotate_display, whatever that option is
[3:28] <ali1234> the option is called lcd_rotate
[3:28] * JMichaelX (~Gregor@unaffiliated/jmichaelx) has joined #raspberrypi
[3:28] <ali1234> what exactly did you put?
[3:29] <jmadero> I followed this: https://www.raspberrypi.org/documentation/configuration/config-txt.md
[3:29] <jmadero> display_rotate 1
[3:29] <jmadero> which like I said, does work very briefly on reboot (about 1 second) then it goes back
[3:30] <ali1234> you are using hdmi?
[3:30] <jmadero> yeah
[3:30] <ali1234> okay that's right then
[3:30] <ali1234> what rotation are you trying to use?
[3:30] <jmadero> 90 degree
[3:31] <jmadero> it's going to be tucked behind a mirror to make a magic mirror.....if I can get it to work
[3:31] <ali1234> okay and what gpu_mem value?
[3:31] <Berg> turn the monitor upside down?
[3:32] <jmadero> 128 for GPU

[3:33] * ziddey (ziddey@sandybridge.home.ijib.com) Quit (Read error: Connection reset by peer)
[3:33] <ali1234> at what point does it flip back to normal rotation?
[3:34] <Smeef> I have xrdp installed on my Pi, when I use aFreeRDP on my android to connect to the Pi, I see all the applications I left open when I last disconnected, but when I use Windows Remote Desktop to connect, I get a new desktop with nothing open. Am I doing something wrong, or it this an issue with x?
[3:34] <jmadero> ali1234: when it boots up it starts (again super brief, almost had to see it) as rotated, then it rotates back (this is all before the full distro is loaded but I can see my background))
[3:34] <ali1234> you see text rotated?
[3:35] <jmadero> I see the mouse rotated
[3:35] <jmadero> that's all
[3:35] <jmadero> desktop icons haven't loaded by that time
[3:35] <ali1234> you don't see the boot messages?
[3:35] <jmadero> not rotated, no
[3:36] <Wurst> Have you checked the boot logs?
[3:36] <ali1234> so you see the boot messages but they aren't rotated?
[3:36] <ali1234> then X is rotated for a short time, then it goes back?
[3:37] <jmadero> precisely
[3:37] <ali1234> does display_rotate 2 work?
[3:37] <jmadero> funny enough, I didn't try, give me a few
[3:38] <jmadero> crap - I need to reinstall raspbian actually, more than a few minutes :)
[3:39] <Wurst> try uncommenting hdmi_force_hotplug=1
[3:39] <ali1234> all commands in config.txt are bootloader commands and they should take effect immediately after the bootloader is finished before any text messages are drawn
[3:39] <Wurst> see if that does anything
[3:39] <ali1234> yes, hdmi complicates things since it can disconnect at runtime
[3:40] <jmadero> okay, downloading NOOBS again so need about 25-30, I'll report back
[3:40] <jmadero> thanks all
[3:40] <vrmxm> So, uh... how long does it take to compile GCC on the Pi?
[3:40] <vrmxm> Since it doesn't seem to use distcc
[3:40] <ali1234> vrmxm: an hour or so
[3:40] <ali1234> more if you are building a full toolchain
[3:40] <vrmxm> That can't be right, this has been going since at least 6... it's now almost 10
[3:40] * WadeWatts_ is now known as WadeWatts
[3:41] <ali1234> are you also building binutils and glibc
[3:41] <ali1234> also what pi?

[3:41] * Ahmed90 (~Ahmed90@unaffiliated/ahmed90) Quit (Quit: Leaving)
[3:41] <ali1234> it shouldn't take excessively long. did you make -j4?
[3:41] <vrmxm> It's -j17 -l4 here
[3:42] <ali1234> 17?
[3:42] <vrmxm> (total cores * 2) + 1
[3:42] <vrmxm> For distcc
[3:42] <ali1234> remember that the sd card is a bottleneck
[3:42] <ali1234> 17 jobs is going to hammer it
[3:43] <ali1234> i dont even know what -l4 means
[3:43] <vrmxm> -l4 is the cores local to the Pi
[3:44] <ali1234> i suspect that gcc compiles a cut down version of itself, and then uses that to compile the main compiler
[3:44] <ali1234> that would explain why distcc isnt working
[3:44] <jmadero> 2-3 hour download so, I might report back tomorrow after work
[3:44] <vrmxm> Probably right
[3:44] <vrmxm> I think I'm going to move the compile space onto the flash drive before I do any more heavy lifting

[4:29] <jKlaus> I guess their angle was to keep the install as minimalist as possible?

[4:30] <jKlaus> Its quite annoying
[4:31] <[Saint]> if the device isn't going to be leaving your network then it is arguable if there is any benefit.

[4:31] <jKlaus> where are the devs of raspbian
[4:32] <jKlaus> [Saint], you still have to reconfigure for the change in router ip address
[4:32] <[Saint]> but you would with static addressing as well.
[4:32] <[Saint]> that's a given.
[4:33] <jKlaus> Yeah.. that's what I was saying

[4:35] <[Saint]> so - yeah, automatic DHCP configuration definitely still works.

[4:35] <jmadero> Qatz: magic mirror :-b
[4:35] <[Saint]> the inet just needs to be set as manual, not automatic.
[4:35] <[Saint]> I have this working myself.
[4:35] <[Saint]> It definitely works.
[4:35] <jKlaus> as I still had to set my dhcpd.conf

[4:36] <jKlaus> [Saint], did you have to set the static router/nameserver
[4:36] <jKlaus> [Saint], please give this a read and tell me what you think..http://raspberrypi.stackexchange.com/questions/37920/how-do-i-set-up-networking-wifi-static-ip
[4:36] <[Saint]> "With the new network mods, DHCP is taken care of by a new package called dhcpcd. In order for this to work, the iface lines in /etc/network/interfaces need to be "manual" rather than "dhcp". This is why the file has changed, and why we've backed it up in case you want to go back, in which case you will need to uninstall raspberrypi-net-mods"
[4:37] <jKlaus> I want to make sure I set it up right
[4:37] <jKlaus> I don't want to have to configure nameserver every time I put my pi on a different network
[4:38] <jKlaus> dang man it must be down pouring outside

[11:05] <gordonDrogon> you could be able to mount it on a PC and edit it..
[11:06] <gcain> Yeh, it's like it's write protected. Even after a format it remounts and all the same files & partitions are there. This is obviously the issue for the Pi too.
[11:06] <Drzacek> Are you mounting with the right access rights (uid and stuff)?
[11:07] <Drzacek> could be the sd card itself broken? can you try with other sd card?
[11:07] <gcain> Yeh, I am pretty sure.
[11:07] <gcain> I don't have another micro one unfortunately...
[11:07] <gcain> Oh wait, I think I do! brb.
[11:07] <Drzacek> ok
[11:09] <Triffid_Hunter> gcain: sounds like a dud card
[11:09] <gcain> Found an older Sandisk one. I'll image it quick and try again.
[11:09] <gcain> And yeh, sounds like a dodgy card unfortunately.

[14:49] <gordonDrogon> you may find hardware PWM won't work.
[14:49] <Zeno`> so yes I should be able to
[14:49] <Zeno`> somehow
[14:49] <gordonDrogon> yes, just set that environment variable.
[14:49] <Zeno`> oh is that it?!
[14:49] <gordonDrogon> you can even set it in your code before you call wiringPiSetup...
[14:49] <Zeno`> lol, too easy... thanks
[14:50] <gordonDrogon> basicalyl you haver dev-tree enabled and the user-land /dev/gpiomem module installed.
[14:50] * BluesKaj_ (~Blues@unaffiliated/blueskaj) has joined #raspberrypi
[14:50] <gordonDrogon> wiringPi doesn't yet test for that by default, but setting the environment variable will make that work.
[14:50] <Zeno`> hmm
[14:51] <Zeno`> wiringPiSetup: Unable to open /dev/gpiomem: Permission denied
[14:51] <gordonDrogon> you need to be in the 'gpio' group.
[14:51] <Zeno`> I should just modify perms for the device?
[14:51] <Zeno`> ok
[14:51] <Zeno`> thanks :)
[14:51] <gordonDrogon> no - add yourself into the gpio group, logout/in again.
[14:51] <Zeno`> yep doing that now

[14:52] <gordonDrogon> I2C & SPI all work in the same way now - use raspi-config to enable them, then make sure your user is in the i2c and spi groups. The default 'pi' user is.
[14:52] <gordonDrogon> I think I'll put some more diagnostics into the gpio program to check for that.... I get so many emails from Linux newbs...
[14:52] <Zeno`> ok, so now I need to add to spi group
[14:53] <Zeno`> perfect
[14:53] <Zeno`> thanks
[14:54] <Zeno`> well I'm not new to linux but that wasn't exactly intuitive
[14:54] <Zeno`> (I mean adding to groups was trivial etc)
[14:54] <Zeno`> but the process overall
[14:56] <Zeno`> I guess if I'd bothered to look at available groups it all would have been a bit more apparent heh
[14:57] <gordonDrogon> yea, it's all a bit odd because, after-all, unix was never designed to let users have this much control over the hardware ...

[15:43] * dreamon (~dreamon@unaffiliated/dreamon) Quit (Remote host closed the connection)
[15:43] <Zeno`> the datasheet says 100 ksps max. sampling rate at VDD = 5V (and 50 ksps @ 2.7V) so 35 ksps on the pi isn't really that bad
[15:44] <Zeno`> The test program is not optimised either (it's all -O0)
[15:44] <Zeno`> so... *shrug*
[15:44] <Sadale> ah. I see. Some ksps downgrade is caused by the bloatness of the library and crap
[15:44] <Zeno`> yeah
[15:44] <Zeno`> well I think gordonDrogon suggested it was the kernel side of things
[15:45] <Zeno`> but I'm happy with 35
[15:45] <Sadale> good :)
[15:45] <Zeno`> I only need 100 samples a second after all (if that) lol

[15:55] <Zeno`> I'd love a c64... I use the emulator all the time (did I just admit that?)

[15:56] <TheLostAdmin> I use the emulator more than the actual C64. It's easier.
[15:56] <Zeno`> the c64 scene is still remarkably alive :D
[15:56] <Zeno`> gotta love that
[15:56] <vrmxm> Well, the restrictions of programming a c64 haven't changed
[15:57] <vrmxm> But there are basically only virtual restrictions on the PC scene now
[15:57] <Zeno`> vrmxm, and hence the enjoyment of using every last cycle
[15:57] <vrmxm> So thhe c64 and Amiga scenes arre still "true"
[15:57] <vrmxm> Indeed
[15:57] <vrmxm> I wonder why there's no stock-pi scene

[16:11] <Zeno`> can that be right?
[16:11] <gordonDrogon> well.. these DACs use the incoming clock to clock through the chip.
[16:12] <Zeno`> reading 1 million samples takes 8 seconds
[16:12] <gordonDrogon> so the max. speed is limited by the speed of the comparitors inside the chip - threy sample on the fly, using the incoming clock rather than free-run.
[16:12] <Zeno`> 16000000 does the same
[16:12] <Zeno`> that's more than the datasheet says it's capable of though
[16:13] <Zeno`> "100 ksps max. sampling rate at V
[16:13] <Zeno`> DD
[16:13] <Zeno`> = 5V"
[16:13] <Zeno`> oops
[16:13] <TheLostAdmin> Is it possible your code is reading the same value multiple times?
[16:13] <gordonDrogon> sure - you can clock it - SPI has no feedback whatsoever to regulate it - the results coming back are probably bogus.
[16:13] <Zeno`> so if I tweak things I can probably push the chip to its limits?
[16:14] <gordonDrogon> there is a SPI speed test program as part of wiringPi source: ~/wiringPi/examples/spiSpeed.c - make spiSpeed ; ./spiSpeed
[16:14] <gordonDrogon> it might let you know the limits.
[16:14] <Zeno`> let me try
[16:14] <gordonDrogon> it tries to measure kernel latency too.

[16:43] <ali1234> i would like something like that for pi, if anyone fancies designing it (and more importantly writing the software drivers)
[16:44] <gordonDrogon> getting high (really high) speed into the Pi is the main issue. You are limited by SPI clock speed, or need to write GPU stuff to use e.g. the camera connector. USB is do-able in theory though...
[16:44] <Zeno`> I actually don't think noise is a problem for what I'm doing (well, I know it's not because I can eliminate it statistically post-facto) but may as well see
[16:44] <ali1234> SMI or bust
[16:45] <ali1234> also there's AVEIN which could probably be abused to read from a ADC @ 20MHz or so
[16:45] <ali1234> but someone has to write drivers

[16:58] <ali1234> faster flash makes the slow ones faster as well

[16:59] <Lartza> Which doesn't get enabled on the Pi
[16:59] <ali1234> correct
[17:00] <Lartza> And will not operate on UHS speeds
[17:00] <ali1234> what you're failing to see is that UHS is the link speed, not the speed the flash operates at

[21:31] <mfa298> Smeef: I don't have a zero, but considering the SoC only has a single USB port on it I'd imagine odd things will happen if you have a hub addon board and something plugged into the microUSB at the same time as they'll be competing with each other
[21:31] <lirakis> vrmxm: ah ill check usb
[21:32] <lirakis> vrmxm: i dont see a usb group in /etc/group
[21:32] <vrmxm> Ok
[21:32] <vrmxm> input??
[21:33] <vrmxm> I don't recall how Debian has its group segregated

[21:33] <lirakis> added myself there

[21:33] <lirakis> nope
[21:33] <lirakis> no audio
[21:34] <vrmxm> What are the permissions on the device node?
[21:35] <Smeef> mfa298, I'm thinking it might be a problem with the hubpixed specifically, I've soldered hubs to my other pi zeros and they work fine either way
[21:35] <lirakis> vrmxm: looks like root:audio
[21:36] <mfa298> Smeef: if you have two things trying to use the same USB port (which you'de also have if you solder on a USB socket and plug something in at the same time) you're going to have issues as USB doesn't work that way.
[21:37] * outofsorts (~outofsort@ Quit (Ping timeout: 276 seconds)
[21:38] <mfa298> if you soldered something on then it might be the signal is degraded so that it only works at USB1 speeds at which point it might appear to work, but I wouldn't count on it working.
[21:38] <lirakis> vrmxm: actually ... this is not true
[21:38] <lirakis> my user seems tobe fine
[21:38] <mfa298> I'd suggest just using the hubpixed and the sockets on it.

[21:41] <lirakis> which is maybe ... why i also have no access to amixer ?
[21:41] <vrmxm> It was a while ago, but I think I recall setting something in ~/.asound.conf or similar
[21:41] <vrmxm> You might gooogle that for specifics
[21:42] <lirakis> call me a liar .. now that im in the audio group i have access to the mixer
