[0:32] <analogist> morfin: not all armv7s are big.LITTLE, right?
[0:32] <analogist> morfin: a7 is probably LITTLE specific tuning
[0:32] <morfin> what do you mean?
[0:32] <morfin> LE and BE?
[0:32] * Smeef (~deathonat@unaffiliated/smeef) Quit (Read error: Connection reset by peer)
[0:33] <morfin> most likely i use LE right now
[0:34] <morfin> as i remember ARM CPU changes mode via some register(?) on early boot stage hmmm
[0:34] <analogist> morfin: probably something related to https://www.phoronix.com/scan.php?page=news_item&px=MTU0NTc for tuning targets
[0:34] <analogist> morfin: IIRC, no first hand experience
[0:34] <morfin> ah

[0:59] <JessicaRN> hey folks, trying to install the newest stretch lite headless. I put "ssh" and "wpa_supplicant.conf" on and made the proper edits. I also made sure that the country code was correct. But the pi never shows up on my router. ideas?

[1:02] <friendofafriend> What are you using for a power supply?
[1:03] <JessicaRN> a 2a wall wart
[1:04] <Khaytsus> faillllllll
[1:04] <Khaytsus> Random phone chargers will not do

[1:05] <JessicaRN> explain
[1:06] <Khaytsus> Dirty output, variable output.... phones don't care. THey have a huge battery between the phone and the supply
[1:06] <Khaytsus> A pi has no filtering, no storage, etc
[1:06] <JessicaRN> this is a wall wart I've used on previous pi's w/o problem
[1:06] <Khaytsus> If you're having power issues, the first thing to try is getting a real PSU. They only cost $7
[1:08] <JessicaRN> Khaytsus: I don't believe I am having power issues. I take that wall wart and plug it into an idential pi and it comes up w/o issue
[1:09] <JessicaRN> I have half dozen of these all running octopi
[1:09] <friendofafriend> Neat, can you take the SD card from one that runs and place it in the Pi that doesn't?
[1:10] <JessicaRN> friendofafriend: I'll do that now
[1:10] <friendofafriend> Good luck to you.

[1:14] <JessicaRN> friendofafriend: new rpi+ old sd+ same wallwart I've been using. It comes up w/o a hitch
[1:14] <friendofafriend> Hey! That's great news!
[1:14] <analogist> JessicaRN: if you’re running truly headless, and don’t have a FTDI or similar serial cable to examine the boot messages, one way to debug is to mount the linux partition on the SD card to examine /var/log/messages
[1:15] * CatCow97 (~mine9@c-24-22-38-85.hsd1.or.comcast.net) Quit (Quit: Textual IRC Client: www.textualapp.com)
[1:15] <JessicaRN> analogist: *smiles* would be nice. Only have a w10 box where I'm at. My ubuntu is at the shop
[1:16] <analogist> JessicaRN: oh if you have two Pi’s, and one you can log into, two wires could the connect UART of the nonbooting one to the other to examine the serial console
[1:16] * cyphase (~cyphase@unaffiliated/cyphase) Quit (Ping timeout: 252 seconds)
[1:17] <JessicaRN> analogist: question: does the MAC follow the SD card, or remain specific to the RPi board? It's the board, right?
[1:17] <friendofafriend> It is on the board.
[1:17] * Geekologist (~me@unaffiliated/geekologist) has joined #raspberrypi
[1:17] <friendofafriend> You would have to change the hostname and any host-specific configuration you've made, but that's not hard with raspi-config.
[1:18] <JessicaRN> hmmm.... I was wondering if I was out of DHCP leases, but that doesn't make sense considering new board is working with old SD card
[1:18] <friendofafriend> I'm quite certain you'll see it has it's own DHCP lease.
[1:19] <friendofafriend> So, you could make an image of a card that works, flash it to the card that doesn't, and see if it's a problem of the software on the card or the hardware of the SD card.
[1:19] <JessicaRN> yeah, but if I'm only handing out 75 ips, and I have a 3 month lease, I could fill up the available IPs, right?
[1:20] <friendofafriend> I don't exactly follow. If you're handing out DHCP leases, it's up to you how they're handled.
[1:20] <analogist> JessicaRN: the MAC is flashed into the PHYS of the WiFi module
[1:21] <analogist> JessicaRN: it’s possible, certainly, if that’s a common number of clients of your network
[1:21] <analogist> JessicaRN: but IPs should be recycled nonetheless
[1:21] <JessicaRN> analogist: I have a private and a guest, and the guest gets a lot of .... guests
[1:23] <analogist> JessicaRN: if your win10 laptop has an eth or USB eth dongle, you can set up internet connection sharing through it, and connect the eth0 of the pi to it to log in
[1:24] * cybr1d (~cybr1d@unaffiliated/cybr1d) Quit (Read error: Connection reset by peer)
[1:24] <JessicaRN> analogist: I'd need a crossover cable to connect directly to the pi, right?
[1:24] <analogist> or set up a WiFi sharing if your on-board WiFi supports it and have wpa_supplicant log into that AP instead
[1:24] * getrat (~getrat@ has joined #raspberrypi
[1:24] * cybr1d (~cybr1d@unaffiliated/cybr1d) has joined #raspberrypi
[1:24] <analogist> JessicaRN: not in this case for a few reasons
[1:24] * cyphase (~cyphase@unaffiliated/cyphase) has joined #raspberrypi
[1:24] <JessicaRN> ?
[1:25] <analogist> JessicaRN: since when you set up win10 to share WiFi to the eth dongle, the win10 laptop is now a gateway with its own LAN and dhcp
[1:25] * cyphase (~cyphase@unaffiliated/cyphase) Quit (Excess Flood)
[1:25] <analogist> JessicaRN: additionally, most PHYs today have automatic crossover support, ever since gigabit became common
[1:26] <analogist> JessicaRN: (but the first reason is more relevant here)
[1:26] * notdaniel (~notdaniel@rrcs-69-75-132-178.west.biz.rr.com) has joined #raspberrypi
[1:27] * cyphase (~cyphase@unaffiliated/cyphase) has joined #raspberrypi
[1:27] <JessicaRN> analogist: the crazy this is that I've done this 1/2 dozen times. The only change is that I'm using the newest stretch build. maybe that's the issue?
[1:27] <JessicaRN> analogist: cool about the xover. I didn't know that
[1:27] <friendofafriend> Use the image from before and update.
[1:27] * cyphase (~cyphase@unaffiliated/cyphase) Quit (Excess Flood)
[1:27] <analogist> JessicaRN: but this stretch build works the other Pi? or am I misreading
[1:28] <JessicaRN> analogist: I made my 2nd most recent build about 2 mths ago with the then current stretch. This new install is using today's stretch
[1:29] <JessicaRN> I'll try friendofafriend suggestion and rebuild using the older stretch img
[1:29] * cyphase (~cyphase@unaffiliated/cyphase) has joined #raspberrypi
[1:29] <friendofafriend> Way to go, keep us posted.
[1:30] <JessicaRN> ty for the healp
[1:30] <JessicaRN> help
[1:30] <analogist> JessicaRN: did you tweak /etc/network/interfaces or anything with this image? I got burned by that once since stretch switched to the systemd model of dhcpcd
[1:30] <friendofafriend> Very welcome, JessicaRN.
[1:31] <JessicaRN> analogist: can't get connected to change it. all I can change is the preboot ssh and wpa_supplicant.conf files
[1:32] <analogist> JessicaRN: boo. good luck!
[1:33] <JessicaRN> ty

[1:34] * Frodox (~CLDX@ Quit (Ping timeout: 252 seconds)
[1:34] <getrat> I want to download something from a relatively trusted source, edit a config with only one option (user + password), put it and the other files on a memory card, put that memory card in my RPI, start the RPI in a corner and forget about it. I want it to do ALL patching/updates on its own, never requiring me to be around and do anything, and absolutely not running any sshd or anything like that. The "control panel" (itself minimal) should be a
[1:34] <getrat> LAN-only-accessible web interface where I simply get to check which software to install. And I would only check "PHP" (CLI) and "PostgreSQL". And then I can use them. Nothing more. Nothing less. Is there such a thing? If not, why?
[1:35] <friendofafriend> No.
[1:35] <getrat> "If not, why?"
[1:36] * clackety (~clackety@gateway/tor-sasl/clackety) Quit (Ping timeout: 256 seconds)
[1:36] <friendofafriend> You'd like it to be up-to-date with no user interaction.
[1:36] <friendofafriend> That will not happen.
[1:37] * clackety (~clackety@gateway/tor-sasl/clackety) has joined #raspberrypi
[1:38] <friendofafriend> You can try to minimize your interaction with the command line, maybe using something like webmin.
[1:39] * cyphase (~cyphase@unaffiliated/cyphase) Quit (Ping timeout: 264 seconds)
[1:40] <getrat> "That will not happen." <-- WHY?
[1:40] <getrat> Isn't this the most basic thing you could ask for from a server in year freaking 2018?
[1:40] * Gathis (~TheBlack@unaffiliated/gathis) Quit (Remote host closed the connection)
[1:40] <getrat> Or am I in a time machine and this is actually the 1950s?
[1:40] <friendofafriend> I see that you're distressed. I know Linux can be confusing.
[1:40] <analogist> I mean, apt already handles automated updates and reboots from apt.sources
[1:41] <analogist> what software stack are you loading with PHP and Postgre?
[1:41] * Neros (~Neros@31-32-241-72.abo.bbox.fr) Quit (Ping timeout: 240 seconds)
[1:42] <friendofafriend> apt can handle software updates automatically, it's not moving you to the next major revision, is it?
[1:42] <getrat> friendofafriend!*@* added to ignore list.
[1:42] * getrat (~getrat@ has left #raspberrypi
[1:43] <friendofafriend> What a mixed up fellow.
[1:43] <analogist> the same upstream will get security patches for 5-10 years, so that's functionally what you want
[1:44] <friendofafriend> Bleh, you're going to have to take out the trash once in a while.
[1:44] <JessicaRN> analogist: friendofafriend That fixed it. I guess there is an issue with headless on the new build
[1:44] <friendofafriend> Is that Rasbian you're loading?
[1:44] <friendofafriend> Sorry, Raspbian**.
[1:45] <friendofafriend> Oh, sorry, Raspbian-based OctoPi, right?
[1:45] <JessicaRN> problem was on today's download of stretch. It's working on a build from March. I'll update/upgrade
[1:45] <JessicaRN> not octopi
[1:46] <JessicaRN> just raspbian stretch
[1:46] <JessicaRN> lite
[1:46] <friendofafriend> I imaged a card with the latest Raspbian Stretch a few days ago, and it worked for what it's worth.
[1:47] <friendofafriend> Maybe you'll have success trying it with your Linux machine, when it's back in your possession.
[1:47] <JessicaRN> cool. well, ty for all the tips.
[1:47] <JessicaRN> g'nite all!

[1:56] <Geekologist> Anyone knows how to remove wirte protection? I've tried diskpart with attributes disk clear readonly and tried with diskpart also with create partition primary to overwrite, nothing works, can't use my pi :(

[1:59] <friendofafriend> Geekologist: Some SD cards will no longer allow write when they have failed. Can you still write to the SD card?
[1:59] <Geekologist> Nope, can't access it at all.
[2:00] <friendofafriend> If you power down the Pi, remove the SD card, and put it into another system, can you write it there?
[2:00] <Geekologist> Nope, windows 10 on both workstation and laptop says write protection
[2:00] <Geekologist> Maybe it's just broken somehow.
[2:00] <analogist> friendofafriend: if they're using diskpart, they've definitely tried it on win10
[2:01] <analogist> Geekologist: might be failing, honestly would try replacing since I wouldn't trust it by that point
[2:01] <Geekologist> Yea, Ithough so too, I'll trow it away and get a new one :)
[2:02] * Kryczek_ is now known as Kryczek

[2:32] * aro (~aro@unaffiliated/aro) has joined #raspberrypi
[2:32] <aro> is there a better-than-others solution of making a raspberry pi read only?
[2:34] <Khaytsus> I personally just make /var/log tmpfs
[2:34] <Khaytsus> that handles most of the writing
[2:37] * dt3k (~dt3k@unaffiliated/dt3k) Quit (Remote host closed the connection)
[2:37] <analogist> aro: there's a full spectrum ranging from tmpfs on some directories with the rest being mountro, to mountro with unionfs, to full initrd/initramfs-only builds. It depends on how much RAM you have, how big your filesystem needs to be, how many times you want the mmcblk to be read, etc
[2:39] * dt3k (~dt3k@unaffiliated/dt3k) has joined #raspberrypi
[2:39] <aro> analogist: I don't really know. I just need it to be able to be powered on/off adhoc
[2:39] <aro> without killing the hardware
[2:39] <analogist> aro: the easiest would be what Khaytsus said, make /var/ tmpfs, or ln -s /var/log into /tmp/ and enlarge /tmp/, on an existing install, then lock down the rest of the disk making it all mountro at boot
[2:40] <aro> i saw adafruit had a script to do it, but it seemed a bit over the top
[2:40] <Khaytsus> 99% of the writing would be in /var/log
[2:40] <Khaytsus> But of course depends on your device
[2:41] <aro> With that being said - is there a way to run a script every 1 minute in read only mode? I saw that there were implications with cron when doing this
[2:41] <Khaytsus> I run cronjobs on mine all the time
[2:42] <analogist> aro: yeah, you'd just remount rw, do some operation, the remount ro, if you want those items to be saved to disk
[2:42] <aro> Ok
[2:43] <aro> would cron be the best way to do that?
[2:44] <aro> i mean, * * * * * will essentially do it every min regardless of the time being correct
[2:44] <Khaytsus> Yes
[2:44] <analogist> it's probably fine in terms of triggering a script, yes
[2:45] <aro> I did create a partition that stores the application I am running, which is mounted as rw. All I write is a gps line into a file
[2:45] <analogist> you'd want to make that script be aware of instances of itself, such as dumping a .pid file into /var/run or something
[2:45] <aro> That is what it is doing
[2:45] <analogist> or some other type of lockfile mechanism, so that if a job runs over it doesn't then try to lock the disk on a previous job
[2:46] <analogist> otherwise it's totally fine as a cronjob
[2:46] <aro> cool ok
[2:46] <Khaytsus> aro: heh, I have a gps tracklogger in my car too... I made sure the ONLY thing writing is the gps data, and it's as unbuffered as possible and closes every write. So the hope is I lose as little data as possible when it shuts down when the car goes down
[2:46] <aro> so just link var/log to the tmp area?
[2:46] <aro> Khaytsus: same :)
[2:47] <Khaytsus> I'd prefer however to have a UPS that'll safely shut it down immediately when the power goes off, power back up later. There are some options, but surprisingly few premade ones that aren't intended for running it full time which I don't want or need
[2:47] <aro> I do have a log file that I use right now, but was going to disable prior to going ro
[2:47] <aro> I had to fashion my own
[2:47] <aro> UPS sort of thing that is
[2:47] * troulouliou_div2 (~troulouli@unaffiliated/troulouliou-div2/x-0271439) has joined #raspberrypi
[2:47] <aro> It works great
[2:47] <Khaytsus> Yeah.. I just need something that'll hit a gpio pin when power is lost to tell the pi to shut down and run the pi for at least 30s or something
[2:48] <Khaytsus> and make sure the pi powers up when power returns
[2:48] <Khaytsus> Some of them require you to push a button to boot again.. wth?
[2:48] <aro> really?
[2:48] <Khaytsus> yeah, I was like......what is the point of this
[2:48] <aro> mine powers on +5v, i have a switch in between right now
[2:49] <Khaytsus> Mine powers straight off aux in my car
[2:49] <aro> like the ignition source?
[2:49] <aro> so when you take keys out, you lose power
[2:49] <aro> are you using a voltage regulator?

[2:50] <Khaytsus> heh nah just a cell charger. It's sufficient for what I need
[2:50] <aro> i am building a working prototype of a tracking application we are making for some of our car lines
[2:51] <aro> mostly the prototype is the API and crap, the rpi is just what i am using to send requests to the api
[2:51] <aro> and the ui of course
[2:52] <Khaytsus> ah.. for me, the pi is getting data from a usb gps and storing it and uploading it to a site when it's on wifi
[2:52] <aro> I am using a waveshare GPS/Cellular module

[2:52] <aro> i installed the GPS antenna attachment in the case for the pi, and that connects to a long antenna thing
[2:53] <aro> and does it over cellular

[14:28] <MacGeek> quick question, a friend recently gave a rpi3b+ to his father for general desktop use. said father, after a day or two, reported having a blue (or grey, apparently he's seen both) circle superimposed on the bottom left corner of the screen.
[14:29] <MacGeek> is it a screen overlay from the firmware, like the lightning bolt for undervoltage?

[14:51] <MacGeek> (you can also see the trash icon on the top left, in the second pic)
[14:51] <gordonDrogon> I'm more thinking its a monitor defect. can he try the monitor with something else?
[14:51] <friendofafriend> I'd run X all by itself.
[14:51] <MacGeek> he has tried the monitor with a win10 laptop and no circle there
[14:52] <gordonDrogon> ok, fairynuff.
[14:52] <MacGeek> I still suspect it may be some overlay generated by the monitor, maybe it doesn't like something about the rpi video output

[15:16] <MacGeek> sorry for the delay, the question has been relayed
[15:17] <MacGeek> it appears there's a hdmi-vga converter between the rpi and the monitor
[15:17] <MacGeek> I'm thinking that maybe underscan is active on the rpi and the converter is generating that circle to try and assist in centering the video signal on the monitor perhaps?
[15:18] <friendofafriend> It seems unlikely the HDMI-to-VGA adapter is the culprit in drawing a circle on the display.

[15:20] <MacGeek> agreed, waiting on an answer to that
[15:20] <friendofafriend> Next, it would be great to know if you can launch X with no window manager and get a desktop free of the circle.
[15:21] <MacGeek> also I guess there may be some way to save a snapshot of the framebuffer from the command line?
[15:21] <MacGeek> so you can see whether the circle comes from the rpi itself or from somewhere down the line
[15:21] <friendofafriend> Right, he could just hit the printscreen button and see if it's being drawn in the screenshot.

[15:33] <exarkun22> Hello. I am running armv7l NixOS on an rpi 3 b+. I just installed the raspberrypi linux kernel, 4.14.50-1.20180619 , and I'm trying to figure out what else I need to do to have gpio access. Currently a trivial wiringPi-based program fails with EPERM when trying to mmap() /dev/mem.

[15:34] <gordonDrogon> exarkun22, wiringPi tried /dev/gpiomem first, but needs root access for /dev/mem. Try with sudo
[15:35] <exarkun22> Sorry, should have mentioned, am running as root
[15:35] <exarkun22> Maybe I got an old version of wiringPi? Looking at strace, I don't see this program trying anything with /dev/gpiomem
[15:36] <exarkun22> eh, claims to be 2.46

[15:43] <exarkun22> Okay thanks.
[15:46] <gordonDrogon> incidentally, wiringPi will never fail. It will kill your program. it's designed to do that, so you can never get EPERM back into your program. wiringPi tries /dev/mem first, then if that fails it tried /dev/gpiomem. If your fails eith EPERM then someone has changed it.
[15:47] * jancoow (~jancoow@dhcp-077-251-034-091.chello.nl) has joined #raspberrypi

[15:54] <gordonDrogon> you must be the first person to actually set WIRINGPI_CODES in the environment.
[15:55] <chris_99> i'm just wondering, i tried to do soemthing funny with /dev/mem on arch possibly, where it wouldn't let me even if root iirc
[15:55] <exarkun22> Hm, don't think I did that
[15:55] <gordonDrogon> I suspect "they" have changed something regarding access - needing some attribute set or something now.
[15:56] <gordonDrogon> and of-course we're not supposed to use /dev/mem that way or something stuipd like that - however no-one has bothered to tell me how to us it now and right now I'm not sure I can be bothered to look it up.

[16:00] * broesel (~broesel@gateway/tor-sasl/broesel) has left #raspberrypi

[16:00] <gordonDrogon> this will affect all gpio - pigpio too as it uses /dev/mem, so maybe I'll read her code to see what to do..

[16:41] <notraven> Hi. I'm pondering a NAS with a Pi, but curious wich SATA-card/controler to use, Wich one do you guys use?
[16:41] <ben_nuttall> we have it for 27, 34, 25, armv6 and armv7 - all combos
[16:41] <ben_nuttall> are you on jessie or stretch (or something other than RPF raspbian)?
[16:41] <waveform> chris_99, when you say it only lists 0.11.0 - is that what's downloading when you run "pip install tensorflow"?
[16:42] <chris_99> so i'm using raspbian stretch in a docker, on alpine. yes it installed 0.11.0 for me
[16:42] <ben_nuttall> what python version?
[16:42] <waveform> ahhhh
[16:42] <chris_99> 3.5.3
[16:43] <ben_nuttall> 0.11 will be the latest available tagged with "py3"
[16:44] <waveform> yeah, but 3.5.3 should match cp35 (and we've got 1.11.0 for cp35)
[16:44] <waveform> hmmm
[16:44] <chris_99> i got '1.11.0' the other day
[16:44] <chris_99> on straight raspbian stretch
[16:44] <chris_99> for python3
[16:44] <ben_nuttall> is it stock python 3.5 or some docker build?
[16:44] <chris_99> i got it from apt-get
[16:44] <waveform> are you sure your python under docker/alpine isn't 3.6 or something?

[16:45] <ben_nuttall> `which python3` and `python3 -V` should help
[16:45] <chris_99> so my python in docker is 3.5.3
[16:45] <chris_99> i don't have python on alpine
[16:46] <chris_99> pip version appears to be 18.1
[16:46] <waveform> chris_99, can you just try "import platform; platform.machine()" in your docker python?
[16:47] <ben_nuttall> if you run `pip3 wheel tensorflow -i https://www.piwheels.org/simple -v > tf.txt` then look at tf.txt it should tell you why it is not picking up 1.11
[16:47] <chris_99> sure one sec
[16:47] <chris_99> waveform: so that is very interesting, that prints aarch64, however when i checked with ctypes it say 32 bit heh i'm confused
[16:47] <waveform> ahhh - that's why you're getting 0.11.0
[16:48] <ben_nuttall> -v gives reasons why it ignores each available file (using -i to only use piwheels otherwise you'll be sifting through all of pypi's wheels)
[16:48] <waveform> it's trying to match the arch and the only install we've got that'll match that arch is the 0.11.0 (which frankly has the wrong arch :)
[16:48] <ben_nuttall> ah
[16:48] <chris_99> can i force the arch?
[16:48] <chris_99> somehow
[16:49] <waveform> erm ... off the top of my head I don't know
[16:49] <chris_99> like it's odd, i think the docker container
[16:49] <chris_99> is 32 bit
[16:49] <waveform> if you can, then you want either armv6l (for Pi1 or Pi0) or armv7l (for Pi3 or Pi2)
[16:49] <friendofafriend> AlexPortable: It won't change anything, because the board and USB devices can only use so much.
[16:49] <chris_99> but maybe it's somehow seeing my alpine arch
[16:50] <friendofafriend> AlexPortable: If the devices you'd like to connect use more power than the Pi can provide, use a split power and data cable.
[16:50] <friendofafriend> AlexPortable: This is an example. https://www.amazon.com/HIGHROCK-Enhancer-Female-Charge-Extension/dp/B00NIGO4NM

[17:20] <pwillard> BUT, I think it relies on a custom distro
[17:21] <JessicaRN> so does the main musicbox
[17:21] <jancoow> I've used a multi room audio solution using pi's only
[17:21] <jancoow> works fine
[17:21] <jancoow> Well. Not only pi's. Also any linux pc
[17:21] <JessicaRN> jancoow: what did you use?
[17:21] * colinjmatt (~colinjmat@matthews-co.uk) has joined #raspberrypi
[17:21] <jancoow> https://www.home-assistant.io/blog/2016/02/18/multi-room-audio-with-snapcast/
[17:23] <jancoow> I want to buy a chrome cast audio once and just drop it off by my server. Then use a pi in each room to stream the audio
[17:23] <JessicaRN> that uses mopidy (musicbox) as well. you having it working reliably?
[17:23] <jancoow> yes, but you can stream from each application AFAI remember
[17:23] <jancoow> so also from microphone input for example
[17:23] <jancoow> or youtube
[17:23] <jancoow> But I used it a long time ago. Don't remember everything exactly
[17:24] <jancoow> What is your use case?
[17:24] <JessicaRN> Oh. you don't use it currently?
[17:24] <jancoow> Nope
[17:24] <JessicaRN> cool.
[17:24] <JessicaRN> ok
[17:24] <JessicaRN> ty
[17:25] <jancoow> I did use it for a short time. But didn't saw the advantage of it because I'm mostly listing music in only one room
[17:25] <jancoow> If I later buy a house I problably gonna set it up again
[17:26] <exarkun22> Okay, got gpiomem working. Yay.
[17:26] <jancoow> But the idea is that you have snapcast running on each device. And then just a chrome cast audio on the wifi network, so I can simply use google play music across my whole house
[17:26] * colinjmatt (~colinjmat@matthews-co.uk) Quit (Ping timeout: 244 seconds)
[17:26] <jancoow> then the server is streaming it to all the pi's
[17:26] <jancoow> and voila
[17:27] <JessicaRN> jancoow: I own an art gallery w/ 9 different rooms. I'd like to sync a music stream to each room and control it from one source preferably.
[17:27] <pwillard> now that I have a Amazon Echo on each floor... thats my audio streaming device now
[17:27] <jancoow> well, then snapcast is the way to go !
[17:27] <jancoow> https://github.com/badaix/snapcast
[17:27] <jancoow> have a look at the readme
[17:28] <jancoow> the latency was pretty good actually
[17:28] <jancoow> even over WIFI
[17:28] * akk (~akk@97-123-90-36.albq.qwest.net) Quit (Quit: +++)
[17:29] <jancoow> I would just use a 3.5mm jack in so you can connect any audio device you want
[17:29] * tachoknight (~tachoknig@ Quit (Remote host closed the connection)
[17:30] <JessicaRN> I'm gonna check out runeaudio first. it looks fairly polished

[17:30] * whysthatso (~whysthats@49-205-50-195.sta.estpak.ee) Quit (Quit: whysthatso)
[17:30] <jancoow> but that isn't multi room audio
[17:31] <jancoow> that's just a player
[17:32] <JessicaRN> jancoow: well, I have a synology that should be able to stream. If I have each room playing the same stream that will handle the problem, won't it?
[17:33] <jancoow> uh
[17:33] * nsk_nyc (~nsk_nyc@network179-254-host-74.inethn.net) has joined #raspberrypi
[17:33] <jancoow> Yeah. I think.
[17:33] <JessicaRN> jancoow: bad idea?
[17:33] <jancoow> Dunno. You lack having 1 control pannel for the whole system
[17:33] * singhyuvraj122 (~singhyuvr@ Quit (Ping timeout: 240 seconds)
[17:34] <jancoow> I would combine snapcast with runeaudio
[17:34] <pwillard> yeah... seems you always have to weigh options
[17:34] <chris_99> Does anyone know if i do file on an elf, if eabi5 version1,and interpretter armhf means the file is an armv7 file, or is there a way to verify that
[17:34] <jancoow> use runeaudio on a nice touchscreen interface and use snapcast to stream to 1..n pi's in the whole building
[17:34] <jancoow> advantage of snapcast is taht it handles the delays
[17:35] <jancoow> so dunno how close your rooms are
[17:35] <jancoow> But I mostly play loud music and it's annoying if subwoofer are out of phase :P
[17:35] <JessicaRN> jancoow: how does if sync?
[17:35] * Lorduncan (~Thunderbi@ has joined #raspberrypi
[17:35] <jancoow> ?
[17:36] <HighInBC> indeed good question
[17:36] <JessicaRN> so, if different rooms are playing the same music, what process does it take to make sure each is in sync with the other?
[17:36] <HighInBC> probably not over the network, latency and such
[17:36] <JessicaRN> there is no mic on the rpi
[17:36] <HighInBC> I am guessing an out of band strobing radio signal
[17:36] <jancoow> " The encoded chunk is sent via a TCP connection to the Snapclients. Each client does continuos time synchronization with the server, so that the client is always aware of the local server time. Every received chunk is first decoded and added to the client's chunk-buffer. Knowing the server's time, the chunk is played out using ALSA at the appropriate time. Time deviations are corrected by "
[17:37] <jancoow> Copy-paste from the readme
[17:37] <JessicaRN> nice
[17:37] <HighInBC> huh that sounds like it would be good to about 10ms
[17:37] <jancoow> HighInBC: correct
[17:37] <HighInBC> which is noticeable
[17:37] <jancoow> it is noticable over wifi, yes
[17:38] <jancoow> "skipping parts or whole chunks
[17:38] <jancoow> playing silence
[17:38] <jancoow> playing faster/slower
[17:38] <jancoow> Typically the deviation is smaller than 1ms. "
[17:38] <jancoow> forget to copy that part
[17:38] <HighInBC> when I was doing animations with RGB leds(ws2812) over multiple controllers I either had to run a sync wire or setup a radio strobe
[17:38] <jancoow> yea
[17:38] <JessicaRN> HighInBC: is it really? considering the speed of sound traveling from one room to the next, can you ever have total syncing for different users in different rooms?
[17:38] <HighInBC> the brain is used to that
[17:39] <jancoow> well. it depends. If you place 2 speakers behind each other which are connected to 1 audio source, you also hear an echo
[17:39] <jancoow> because of the speed of sound
[17:39] <JessicaRN> I wonder what the offset is for a 12 string guitar
[17:39] <JessicaRN> prob minimal

[19:18] <mlelstv> the rpi itself won't need that much

[19:19] <gordonDrogon> no such thing as an average Pi user.
[19:19] <AlexPortable> can i measure it on the pi somehow?

[20:39] <solsTiCe> hi. I wanted to automate pulling a little lever. So I need some kind of little robotic arm to be controlled from a rpi. I have not searched for that yet. Could you point me in some direction ?
[20:40] <solsTiCe> What could be the expected cost of this arm ? without the rpi
[20:40] <Khaytsus> solsTiCe: https://en.wikipedia.org/wiki/Drinking_bird
[20:40] <BCMM> solsTiCe: "robotic arm" seems a bit overkill
[20:41] <BCMM> solsTiCe: the term would generally refer to something with a joint that is capable of moving in any direction
[20:41] <Khaytsus> selenoid... or a small motor that rotates a gear...
[20:41] <BCMM> when it sounds like you just need something that will move backwards and forwards
[20:41] <Khaytsus> all seems sufficient. But of course we don't know what you're actually doing
[20:41] <chris_99> what's the lever for
[20:43] * mgottschlag (~quassel@reactos/tester/phoenix64) Quit (Ping timeout: 252 seconds)
[20:44] <solsTiCe> yes you are rights. just up and down
[20:45] <BCMM> solsTiCe: so how far do you need this lever to move?
[20:45] <solsTiCe> just a sec
[20:45] <BCMM> solsTiCe: point is, you can probably do it with something like this, plus a relay: http://www.hobbytronics.co.uk/solenoid-5v
[20:46] <BCMM> (random link from google, not a specific recommendation)
[20:47] <solsTiCe> so it should 5 cm up. and go up and down rouglhy 5cm. it's to move (sorry to break the mystery) the lever on that https://www.darty.com/nav/achat/petit_electromenager/petit-dejeuner/bouilloire_theiere_chocolatiere/moulinex_by540d10_subito.html
[20:48] <BCMM> solsTiCe: careful with that. for some kettles, holding down the lever will override the built-in protections
[20:48] <solsTiCe> sorry and go up and down roughly 1cm
[20:48] <BCMM> i.e. if you mess this up, it will boil dry, melt, and catch fire
[20:49] * JK-47 (RJ@2600:3c03::f03c:91ff:fe73:fc8) has joined #raspberrypi
[20:49] <solsTiCe> I don't want to hold. just push down but don't block it else it will keep it up and turn on
[20:50] <BCMM> solsTiCe: i know you don't want it to hold. just keep in mind that holding is one potential mode of failure.

[20:51] * Tobbi (~Tobbi@supertux/tobbi) Quit (Quit: My MacBook has gone to sleep. ZZZzzz…)
[20:51] <BCMM> anyway, solenoid with 1cm throw. they also have diagrams of how to connect it to gpio. https://thepihut.com/products/adafruit-large-push-pull-solenoid
[20:52] <solsTiCe> BCMM: yes ok. jsut a simple motor that you can control rotation, like 60° rotation in 3s. with a wood hand crafted gear should do it
[20:52] * korryd (~korryd@va-76-4-65-131.sta.embarqhsd.net) Quit (Quit: My MacBook has gone to sleep. ZZZzzz…)
[20:52] <BCMM> solsTiCe: that would work too, but you can already buy a device that produces linear motion, if that's what you want
[20:53] <BCMM> solsTiCe: just pay attention to how you connect to gpio, basically. the gpio pins won't power much beyond a simple LED on their own, so you'll need a transistor or relay to switch it on.

[20:57] <BCMM> (click "Specifications" here https://www.raspberrypi.org/products/poe-hat/ )
[20:57] <solsTiCe> BCMM: yes your solenoid could work. But thinking of failsafe behavior I think now that the gear if well crafted could be more failsafe.
