**** BEGIN LOGGING AT Tue Sep 03 03:00:09 2019
Sep 03 04:30:48 <poboy_> hey all, having trouble SSH'ing into my beaglebone black at 192.168.7.2.  I can access it via "screen /dev/ttyACM0" but can't ping it. ifconfig shows usb0 at 192.168.7.2 and usb1 at 192.168.6.2. dmesg output is here: https://pastebin.com/raw/vyt1CA0V
Sep 03 04:31:53 <mawk> what ip did you pick poboy_ ?
Sep 03 04:31:56 <mawk> for your computer
Sep 03 04:32:01 <mawk> you need 192.168.7.3
Sep 03 04:32:11 <mawk> otherwise it won't respond
Sep 03 04:32:33 <poboy_> as in "ping 192.168.7.3" from the host? sorry not sure I understand
Sep 03 04:33:12 <mawk> no, you assign the address 192.168.7.3/31 to your host
Sep 03 04:33:14 <mawk> to usb0
Sep 03 04:33:25 <mawk> then you can ping 192.168.7.2
Sep 03 04:33:32 <mawk> if you're not on the same network you can't ping it
Sep 03 04:34:34 <poboy_> ahh, I see. so I suspect I'm having an issue there. this is my ifconfig output from my host (arch linux): https://pastebin.com/raw/JYfMtUzc
Sep 03 04:34:48 <mawk> uh
Sep 03 04:34:50 <poboy_> the enp0's are for the BB I believe
Sep 03 04:34:51 <mawk> can you use ip instead ?
Sep 03 04:34:52 <mawk> ip -br a
Sep 03 04:34:56 <mawk> way nicer output
Sep 03 04:35:09 <mawk> ah yeah no nevermind
Sep 03 04:35:13 <mawk> the addresses aren't set, that's all
Sep 03 04:35:23 <mawk> you can assign the address manually poboy_ but I don't know which interface is which
Sep 03 04:35:54 <mawk> ok usb0 is fc:69:47:21:1a:76
Sep 03 04:36:00 <mawk> and you said that's 192.168.7.2/31
Sep 03 04:36:01 <mawk> ok
Sep 03 04:36:10 <poboy_> didn't know about that command, TIL
Sep 03 04:36:15 <mawk> so you do on your host ip addr add 192.168.7.3/31 dev enp0s20u3
Sep 03 04:36:26 <mawk> the unabbreviated command is ip -c addr
Sep 03 04:36:29 <mawk> (-c is for color)
Sep 03 04:36:30 <mawk> it's very nice
Sep 03 04:36:34 <mawk> ifconfig is deprecated
Sep 03 04:36:51 <mawk> I have to go, hope my last suggestion works (it should), good night !
Sep 03 04:36:58 <mawk> run as root
Sep 03 04:37:01 <poboy_> thank you!
Sep 03 04:37:31 <mawk> it's just a quick fix tho, normally you just use dhclient or your system's network manager to automatically get an ip on it
Sep 03 04:37:35 <mawk> you can do it with the GUU
Sep 03 04:37:40 <mawk> GUI
Sep 03 04:37:46 <mawk> but now you know the command to manually add an ip to an interface, it's useful knowledge
Sep 03 04:38:00 <poboy_> I've got 192.168.7.3/31 set now but still not connecting
Sep 03 04:38:09 <poboy_> i can ask someone else in the chat
Sep 03 04:38:12 <poboy_> don't want to keep you
Sep 03 04:38:19 <mawk> maybe you mixed the two addresses ?
Sep 03 04:38:23 <mawk> remove it and add the other one
Sep 03 04:38:39 <mawk> ip addr flush dev enp0s20u3; ip addr add 192.168.6.3/31 dev enp0s20u3
Sep 03 04:38:42 <mawk> to use the other range
Sep 03 04:38:49 <mawk> good luck
Sep 03 04:39:16 <poboy_> thank you :)
Sep 03 05:02:47 <poboy_> still having some trouble, if anyone else is free to help. I'm digging around a bit more and it looks like "ssh root@192.168.7.2" is going through my wlo1 interface instead of enp0s20u3 (based on wireshark)
Sep 03 05:05:09 <poboy_> "route -n" looks like this https://pastebin.com/raw/FsLtM2fa ; is the host driver supposed to add new routes for the beaglebone?
Sep 03 07:05:11 <zmatt> poboy_: can you show the relevant output from "ip addr" and "ip route" (I don't really know what the output from legacy tools like "route" is supposed to look like)
Sep 03 07:05:33 <zmatt> and your network manager is responsible for bringing the interface up, not a driver
Sep 03 07:07:26 <zmatt> normally it's not a great idea to try to manually mess with the configuration using 'ip addr'
Sep 03 07:14:06 <poboy_> sure thing @zmatt
Sep 03 07:14:15 <poboy_> ip addr: https://pastebin.com/raw/dAsqKsig
Sep 03 07:14:19 <poboy_> ip route: https://pastebin.com/raw/rw2FEBwY
Sep 03 07:14:24 <poboy_> ^ these are for the host machine
Sep 03 07:15:03 <poboy_> this was after manually setting the ip address with mawk's command to 192.168.7.3
Sep 03 07:15:09 <zmatt> which I'm 99% is wrong
Sep 03 07:15:25 <zmatt> *99% sure
Sep 03 07:15:46 <poboy_> I'm using NetworkManager for arch linux, when I connect it normally it tries to initialize a "Wired Connection" and fails after a minute or so
Sep 03 07:15:59 <zmatt> I don't recommend trying to configure it manually, use dhcp
Sep 03 07:16:22 <zmatt> that's weird... but then, it's Arch.  it seems nothing works there by default without some manual hammering :P
Sep 03 07:16:32 <zmatt> on most linux systems it just works plug&play
Sep 03 07:16:45 <poboy_> yeah... though it doesn't work on my windows laptop either
Sep 03 07:17:35 <poboy_> I'm getting a lot of weird inconsistencies: looking at the TCP handshake in wireshark, my host isn't ACK'ing the BB's SYN/ACK
Sep 03 07:17:48 <poboy_> also, my lsusb output is giving me a different vendor ID than what's in the mkudev script
Sep 03 07:18:06 <zmatt> "the mkudev script" ?  you shouldn't need any
Sep 03 07:18:21 <zmatt> normally no host configuration is required
Sep 03 07:18:36 <poboy_> ahh, cool
Sep 03 07:18:38 <poboy_> https://learn.adafruit.com/ssh-to-beaglebone-black-over-usb/installing-drivers-linux
Sep 03 07:18:48 <poboy_> was using this one but I'll delete the rule, doesn't look like it was triggering anyway
Sep 03 07:20:14 <zmatt> installing drivers it not needed on any of the three platforms nowadays, this guide is probably just ancient
Sep 03 07:21:25 <zmatt> "FTDI" seems to imply it was for the integrated ftdi serial converter for the serial console on the old beaglebone (not present on the beaglebone black)
Sep 03 07:22:38 <poboy_> ah, makes sense
Sep 03 07:22:44 <poboy_> so I'm trying to debug my networkmanager now
Sep 03 07:22:53 <poboy_> https://pastebin.com/raw/ebWz7Wfk <-- this is the output of journalctl -u NetworkManager.service
Sep 03 07:23:11 <poboy_> do you know if there's anything wrong there?
Sep 03 07:23:36 <zmatt> what does your network config ('ip addr' and 'ip route') look like when you don't mess with it and just let NM do its thing?
Sep 03 07:23:52 <zmatt> hmm, DHCP timeout on both interfaces?
Sep 03 07:24:11 <zmatt> that is weird
Sep 03 07:24:49 <poboy_> ip addr: https://pastebin.com/raw/uSRfFgPW
Sep 03 07:24:55 <poboy_> ip route: https://pastebin.com/raw/aDB1Mj2r
Sep 03 07:26:14 <zmatt> if you haven't already, try reflashing your BBB to the latest stretch-iot image... although I can't imagine how it could present two usb network interfaces yet fail to give out a DHCP lease
Sep 03 07:27:36 <poboy_> I was hoping to not resort to that, don't really have a spare microSD atm,
Sep 03 07:27:53 <poboy_> I managed to get it working once and ran the update_kernel.sh so i think it should be updated at least
Sep 03 07:28:03 <poboy_> uname -a: Linux beaglebone 4.19.50-ti-rt-r20 #1jessie SMP PREEMPT RT Fri Jun 21 19:45:01 UTC 2019 armv7l GNU/Linux
Sep 03 07:28:32 <zmatt> oh god, you're running an ancient system but with a 4.19 kernel?
Sep 03 07:28:46 <zmatt> and it used to work, but no longer does... :P
Sep 03 07:29:02 <zmatt> and you didn't figure it might be due to your actions? :P
Sep 03 07:29:09 <poboy_> lol, wait what part of that is ancient?
Sep 03 07:29:13 <zmatt> "jessie"
Sep 03 07:30:02 <zmatt> although... does that normally end up in uname -a ?
Sep 03 07:30:09 <zmatt> what does "cat /etc/dogtag" say ?
Sep 03 07:30:18 <zmatt> assuming you have a way in (serial console or such)
Sep 03 07:30:28 <poboy_> dogtag: BeagleBoard.org Debian Image 2016-01-24
Sep 03 07:30:36 <zmatt> aaaaancient system
Sep 03 07:30:55 <poboy_> lol, I had no idea that was considered ancient
Sep 03 07:31:10 <poboy_> guess I ought to find a uSD then
Sep 03 07:31:28 <zmatt> and the current default kernel series is 4.14-ti
Sep 03 07:32:40 <poboy_> alright, gonna reflash and report back
Sep 03 07:32:54 <poboy_> thanks for your help btw
Sep 03 08:26:33 <pubggod> Hi
Sep 03 08:36:05 <zmatt> lol that name
Sep 03 11:41:03 <mawk> I realized it's /30 not /31
Sep 03 11:41:11 <mawk> poor poyboy_
Sep 03 11:41:22 <zmatt> .3 is also wrong, it should be .1 or .2
Sep 03 11:41:40 <zmatt> iirc the host is .1 and the beaglebone is .2
Sep 03 11:41:52 <zmatt> regardless, manual configuration should never be needed
Sep 03 11:42:06 <zmatt> when dhcp is failing, there's more going on
Sep 03 13:54:50 <flj> https://libreboot.org/docs/install/bbb_setup.html It says, you can install a free software system on the beaglebone black in order to use it to flash libreboot. It does not say how to install a free software system? Do you know how to install it? Thank you.
Sep 03 14:03:28 <zmatt> https://beagleboard.org/latest-images
Sep 03 14:05:18 <flj> free software is software you may use, share, modify and redistribute. The debian 9.5 lxqt is not?
Sep 03 14:05:32 <zmatt> what on earth makes you think it isn't
Sep 03 14:06:07 <zmatt> it's debian
Sep 03 14:06:41 <zmatt> anyway, if you have any questions about the content on a libreboot.org page, maybe ask in #libreboot, not here
Sep 03 14:07:29 <kremlin> m
Sep 03 14:07:50 <zmatt> jkridner[m]: something weird happened to the styling on the getting-started page... the main text uses a huge font size compared to the navigation links and compared to content on other pages
Sep 03 14:11:50 <flj> https://www.debian.org/doc/debian-policy/ch-archive.html The none free repositories are enabled in bbb debian 9.5 lxqt? The firmware is non free?
Sep 03 14:12:14 <flj> I will not ask on irc libreboot.
Sep 03 14:12:18 <zmatt> no closed-source firmware exists for the bbb
Sep 03 14:13:09 <zmatt> actually that's poorly phrased
Sep 03 14:14:18 <zmatt> the only parts of the BBB that need firmware loaded at runtime are the power-management cortex-m3 and the GPU... the cortex-m3 firmware is open source, the GPU is typically unused and its firmware doesn't ship on the default images
Sep 03 14:15:18 <zmatt> I don't exclude there may be other firmware shipped on the default images, e.g. for usb peripherals.  pretty much nobody cares, if you do then feel free to put in the effort of removing such firmware
Sep 03 14:16:18 <flj> When I update debian 9.5 it appears contrib repository is enabled. You do not get non free software from that repository? Is the non free archive enabled?
Sep 03 14:16:54 <zmatt> if you want an image that meets some criteria you care about, then feel free to make one.  if none exists, then that just means that apparently nobody cares enough about these criteria to put in the effort of making such an image
Sep 03 14:17:11 <zmatt> I have no idea since I don't care
Sep 03 14:17:17 <flj> For free software people it is important.
Sep 03 14:17:29 <zmatt> then ask them
Sep 03 14:17:55 <jkridner[m]> zmatt: Riot isn't giving me a friendly scrollback....
Sep 03 14:17:59 <jkridner[m]> what is up with the getting started page?
Sep 03 14:18:08 <zmatt> jkridner[m]: font size is all weird
Sep 03 14:18:30 <jkridner[m]> I did try to make it bigger, easier to read.
Sep 03 14:18:31 <zmatt> the main body of the getting-started page (and seemingly *only* the getting-started) page is huge
Sep 03 14:18:36 <jkridner[m]> maybe I didn't do it right.
Sep 03 14:18:39 <flj> I will. First I asked here because maybe people here know what there is to know about the bbb.
Sep 03 14:19:09 * jkridner[m] uploaded an image: Screenshot from 2019-09-03 10-18-51.png (348KB) < https://matrix.org/_matrix/media/v1/download/matrix.org/iyYRjiWuuuokRBSxTbEUvBfV >
Sep 03 14:19:18 <jkridner[m]> look different for you?
Sep 03 14:19:23 <zmatt> flj: I told you the bbb-relevant part: the bbb itself doesn't require any non-free firmware (except for the gpu, which is typically unused and its closed source components do not ship by default)
Sep 03 14:20:03 <zmatt> jkridner[m]: yeah the font size difference is way bigger here
Sep 03 14:20:28 <zmatt> or maybe the overall size is bigger here
Sep 03 14:20:39 <zmatt> anyway, the overall result looks really bad
Sep 03 14:21:19 <zmatt> the text is also huge compared to the navigation links, compared to every other bb.org page, and compared to pretty much any website
Sep 03 14:21:33 <kremlin> when you go there you need to try swimming in the ocean
Sep 03 14:21:37 <kremlin> wrong chat
Sep 03 14:22:30 <jkridner[m]> any better?
Sep 03 14:23:52 <zmatt> I mean, it's closer to what it was, hence less bad :P   the main problem is the inconsistency... most pages on the site make me want to zoom in to increase font size, the getting-started page makes me want to zoom out to decrease font size
Sep 03 14:24:15 <zmatt> (but of course chrome remembers zoom per site, not per page)
Sep 03 14:24:54 <zmatt> I feel like it was fine the way it was... browsers already provide users with control over font size
Sep 03 14:26:32 <flj> https://elinux.org/Beagleboard:Expanding_File_System_Partition_On_A_microSD When I followed the instructions I did not know what to answer under step p. 1 or 2? Later there was a message about deleting a signed file. I did not know if I should enter yes or no? If I start the bbb will you go through the instructions?
Sep 03 14:27:40 <zmatt> flj: what steps?  like it says at the top, the only step is "sudo /opt/scripts/tools/grow_partition.sh"
Sep 03 14:27:56 <jkridner[m]> zmatt: k. the problem is reviewing the font size on all the pages....
Sep 03 14:28:01 <jkridner[m]> I want them all to be bigger....
Sep 03 14:28:12 <zmatt> jkridner[m]: you don't have global css ?
Sep 03 14:28:21 <jkridner[m]> guess I'll update the common.css to what getting-started shows and then start fixing issues as they are pointed out. :-/
Sep 03 14:30:52 <flj> I referring to the instructions under Expanding the File System Partition. Because I do not know what to do with the script you are referring to.
Sep 03 14:31:50 <zmatt> you run it.  the rest of that page is obsolete information
Sep 03 14:32:45 <zmatt> (actually it might still be correct, but it is just unnecessarily error-prone)
Sep 03 14:32:55 <flj> Do I copy and paste the script into a textfile and then write the command you stated?
Sep 03 14:32:56 <rcn-ee[m]> flj: the "latest" "iot" image has the sgx enabled by default, so based on some of your questions above, you'll want to stick away from that.. unless you don't mind uninstalling it..
Sep 03 14:33:16 <zmatt> rcn-ee[m]: it does? interesting
Sep 03 14:33:34 <zmatt> I'm glad to hear that
Sep 03 14:33:43 <rcn-ee[m]> yeap, full access to "EGL" non-windowed acceleration. ;)
Sep 03 14:34:05 <rcn-ee[m]> it's been that way for maybe 2 months...
Sep 03 14:34:09 <zmatt> flj: you don't do anything with any text file, you just literally type "sudo /opt/scripts/tools/grow_partition.sh" and press enter
Sep 03 14:34:26 <rcn-ee[m]> (non-windowed = non-xorg)
Sep 03 14:34:45 <zmatt> rcn-ee[m]: wayland when? ;)
Sep 03 14:35:27 <flj> what is an iot image?
Sep 03 14:35:30 <rcn-ee[m]> there's a few ti patches on top of wayland...
Sep 03 14:35:42 <rcn-ee[m]> flj, look at the file name.. if says it's iot it's iot..
Sep 03 14:36:36 <jkridner[m]> k. made some global edits to common.css.
Sep 03 14:36:40 <jkridner[m]> feedback welcome.
Sep 03 14:37:23 <zmatt> seems okay at first sight
Sep 03 14:38:15 <jkridner[m]> grrr...
Sep 03 14:38:26 * jkridner[m] uploaded an image: Screenshot from 2019-09-03 10-38-09.png (578KB) < https://matrix.org/_matrix/media/v1/download/matrix.org/lyqPMSCkSLFYhVVmkjCGGzhs >
Sep 03 14:38:34 <jkridner[m]> pages like that are going to be tougher....
Sep 03 14:38:41 <jkridner[m]> might have to reduce font size in tables.
Sep 03 14:39:17 <flj> rcn-ee: you are in-talking. I do not know what iot is? By sgx I do not know if you are referring to debian 9.5?
Sep 03 14:39:52 <jkridner[m]> put td back to 1.1em
Sep 03 14:39:54 <zmatt> the debian version is irrelevant, it's about whether or not some optional packages are installed by default
Sep 03 14:40:09 * jkridner[m] would have thought 1em would look reasonable, but it seems 1.3em is where things look nice.
Sep 03 14:40:57 <flj> so the sgq remark was about debian 9.5? Not about resizing the file system?
Sep 03 14:40:59 <zmatt> "iot" is referring to the type of image (which basically means the selection of packages installed by default), which is clearly indicated in the download link and - like rcn said - in the file name of the image
Sep 03 14:41:23 <zmatt> it had nothing to do with resizing the image
Sep 03 14:41:40 <zmatt> resizing the image is just a matter of executing the command I've mentioned twice so far
Sep 03 14:42:34 <flj> you do not have to download anything, only enter the command?
Sep 03 14:42:45 <jkridner[m]> grrr.... what is going on with the certificate? looks like the wrong one is being supplied?
Sep 03 14:43:34 <zmatt> flj: that's literally what I said
Sep 03 14:43:53 <zmatt> jkridner[m]: seems to be fine?
Sep 03 14:44:00 <zmatt> I get no certificate warnings
Sep 03 14:44:31 <jkridner[m]> odd.
Sep 03 14:44:38 <flj> I got the impression that you had to download something.
Sep 03 14:44:41 <jkridner[m]> I'm getting one on https://beagleboard.org/boards
Sep 03 14:45:00 <zmatt> jkridner[m]: certs are never page-dependent
Sep 03 14:45:35 <zmatt> I'm not seeing any problems for beagleboard.org
Sep 03 14:45:41 <jkridner[m]> I might have some images linked via http ... looking.
Sep 03 14:45:48 <vagrantc> i get a valid cert but various images are http://
Sep 03 14:46:09 <zmatt> that's not good, but doesn't have anything to do with certs :P
Sep 03 14:49:10 <jkridner[m]> nope..... so odd..... the bbb.io certificate keeps being served up to me.
Sep 03 14:49:38 <zmatt> bbb.io is the primary name yeah, but the subject alternate names cover all the relevant domains
Sep 03 14:49:43 <zmatt> it seems to be one cert for everything
Sep 03 14:50:36 <jkridner[m]> I'm wondering if we have different certs cached.
Sep 03 14:50:45 <zmatt> certs are not cached
Sep 03 14:50:50 <jkridner[m]> I've got an Aug 24 cert....
Sep 03 14:50:51 <jkridner[m]> doesn't have any of the aliases.
Sep 03 14:51:12 <zmatt> huh
Sep 03 14:51:30 <zmatt> actually this might be the aug 24 if it adjusted the time for timezone
Sep 03 14:52:30 <zmatt> serial number 04:DF:CC:EC:0D:7F:B4:60:B9:6C:6A:14:72:FD:55:01:66:E8
Sep 03 14:53:40 <zmatt> yeah, issued 2019-08-24 23:17:39 UTC
Sep 03 14:54:28 <jkridner[m]> Just looked at my letsencrypt scripts..... beagleboard.org has it's own cert.... several are thrown in with bbb.io, but beagleboard.org doesn't appear to be one.
Sep 03 14:54:39 <zmatt> https://pastebin.com/ZpGmx95Z
Sep 03 14:54:47 <zmatt> that's the list of subject alternate names in the cert
Sep 03 15:00:52 <jkridner[m]> do you have the serial number for that cert?
Sep 03 15:01:08 <zmatt> I just gave it
Sep 03 15:01:21 <jkridner[m]> oh, I see it.
Sep 03 15:01:31 <jkridner[m]> any the cert I'm getting has those DNS entires as well. :-/
Sep 03 15:02:01 <zmatt> like I said, it's a valid cert as far as I can tell (and as far as chrome is concerned)
Sep 03 15:02:22 <jkridner[m]> well, Chromium says "Not secure"
Sep 03 15:03:51 <zmatt> because it embeds images loaded from non-https urls apparently
Sep 03 15:03:57 <zmatt> or... used to.  it says secure now
Sep 03 15:09:25 <flj> resizing worked. Thanks. Should you not write it on https://elinux.org/Beagleboard:Expanding_File_System_Partition_On_A_microSD?
Sep 03 15:09:51 <zmatt> it's already there, right at the top.  I copy-pasted the command from that page
Sep 03 15:10:26 <rcn-ee[m]> flj: it's also here: https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Expanding_File_System_Partition_On_A_microSD  which is the same base url that shows up on the serial and ssh consoles when you login..
Sep 03 15:14:15 <flj> the command is not on https://elinux.org/Beagleboard:Expanding_File_System_Partition_On_A_microSD.
Sep 03 15:15:09 <zmatt> flj: maybe you need glasses?
Sep 03 15:15:45 <zmatt> it's right there, near the top of the page, and like I just said I literally copy-pasted the command from that page
Sep 03 15:16:08 <zmatt> could it be clearer? yes.  but it is still right there
Sep 03 15:16:16 <flj> then tell me where exactly on the website the command displays?
Sep 03 15:17:11 <zmatt> first sentence under the header "The automated way"
Sep 03 15:17:45 <flj> you are right. I did not notice.
Sep 03 15:19:00 <flj> I read it like I should download a file from the link.
Sep 03 15:20:21 <zmatt> your inability to read what it says is not my problem.  now if you don't mind, you've generously exceeded your support quota for today.  if you need more help, please seek it elsewhere
Sep 03 15:25:07 <flj> I explained why I did not think of the command as a stand alone command.
Sep 03 15:26:56 <rcn-ee[m]> convert that section to a code block, maybe it'll help ;)
Sep 03 15:34:08 <jkridner[m]> well, this at least got me to update openssl
Sep 03 15:34:28 <jkridner[m]> https://www.ssllabs.com/ssltest/analyze.html?d=beagleboard.org&latest now returns an "A" rating..... was an "F".
Sep 03 21:58:42 <Teknaturk> Hello people, I need help about my Beaglebone Black internet connection via USB
Sep 03 21:58:55 <kremlin> wsup
Sep 03 21:59:09 <Teknaturk> wsup
Sep 03 22:00:27 <Teknaturk> I have tried route add default gw 192.168.7.1. you know
Sep 03 22:00:39 <Teknaturk> But it doesnt solve the problem
Sep 03 22:00:44 <Teknaturk> it cant even ping 8.8.8.8
Sep 03 22:01:11 <kremlin> that IP is should be the IP of the beagle itself
Sep 03 22:01:22 <kremlin> your route IP will be like 192.168.1.1 or similar

Sep 03 22:06:22 <TeknaTurk57> How can I check what my ip is ?
Sep 03 22:06:25 <TeknaTurk57> ifconfig ?
Sep 03 22:08:12 <TeknaTurk57> I checked again on my computer and it shows 192.168.7.1
Sep 03 22:56:20 <set_> Just for a notice, I got a transistor, mawk, to perform LED circuitry and to program LEDs.
Sep 03 22:56:47 <set_> When resistors do not handle the load properly, I can use a transistor.
Sep 03 23:03:03 <set_> I will try a FET too w/ a resistor.
Sep 03 23:03:04 <set_> Boy!
Sep 03 23:03:10 <set_> Things are finally picking up.
Sep 03 23:04:20 <set_> I found a funny book from REA on circuitry. I am going to use it to try to use the couple of libraries I have found.
Sep 03 23:52:26 <set_> I am hooked and hooked up. I am getting ready to use a bs270 w/ a resistor and LED. Geaux BBB!
Sep 03 23:52:42 <set_> '95 in the house!
Sep 04 00:03:53 <mawk> hi set_
Sep 04 00:03:58 <mawk> back with electronics questions ?
Sep 04 00:04:25 <set_> Sure.
Sep 04 00:04:42 <mawk> geaux is french for go ?
Sep 04 00:04:52 <set_> Hello mawk: Do you know how to use a bs270 w/ Python?
Sep 04 00:04:53 <set_> Oh.
Sep 04 00:04:54 <set_> No.
Sep 04 00:05:04 <set_> geaux is cajun-french for go.
Sep 04 00:05:14 <set_> It is a rip off of the original language.
Sep 04 00:05:31 <mawk> in french it would be pronounced jo
Sep 04 00:05:35 <mawk> ge is like j
Sep 04 00:05:46 <set_> Oh.
Sep 04 00:05:46 <mawk> if you drop the e it's like go
Sep 04 00:05:54 <set_> Nice. shhjo!
Sep 04 00:07:01 <set_> I was going to use C++ w/ the bs270 to light my LED. I was going to try my "other" favoriate language, C++, to light it, too.
Sep 04 00:08:00 <set_> I have the book from Molloy on the BBBW. I am using it to promote new findings in ciruitry.
Sep 04 00:10:27 <mawk> you have a mosfet
Sep 04 00:10:37 <set_> Yea. I finally got them in.
Sep 04 00:10:53 <set_> FET over here!
Sep 04 00:11:01 <mawk> mosfet is supposedly a symmetric device, drain and source being interchangeable
Sep 04 00:11:14 <mawk> but effectively they are made such that current should flow from drain to source
Sep 04 00:11:24 <mawk> especially with "power" or "large" mosfets that have a parasitic body diode
Sep 04 00:11:26 <mawk> like yours
Sep 04 00:11:37 <mawk> so, current will flow from drain to source
Sep 04 00:11:41 <set_> d to s, got it.
Sep 04 00:11:54 <mawk> now, the N-mosfet will activate when the gate will be "way higher" than the source
Sep 04 00:12:01 <mawk> so it's better to use it on the "low side" of the LED
Sep 04 00:12:03 <mawk> the ground side
Sep 04 00:12:10 <mawk> like with a NPN transistor
Sep 04 00:12:20 <mawk> let me show you
Sep 04 00:13:28 <set_> So, I would go from sys_5v to resistor to LED to source to drain to GND?
Sep 04 00:14:02 <set_> and g, or my input, would go to a GPIO?
Sep 04 00:14:25 <set_> Not very visual but I think that is correct.
Sep 04 00:14:39 <set_> ...
Sep 04 00:14:55 <set_> I just got a new image. So, I am updating and upgrading my image now.
Sep 04 00:15:05 <mawk> http://tinyurl.com/y56epkr4
Sep 04 00:15:29 <set_> mawk: Forbidden!
Sep 04 00:15:50 <set_> That tinyurl.com/y56opkr4 is Forbidden on my end.
Sep 04 00:16:00 <mawk> falstad doesn't like your computer
Sep 04 00:16:05 <set_> I bet.
Sep 04 00:16:09 <set_> falstad?
Sep 04 00:16:52 <mawk> the circuit simulator
Sep 04 00:17:00 <mawk> https://www.falstad.com/circuit/circuitjs.html?cct=$+1+0.000005+23.47059216675035+50+5+50%0AR+752+400+752+320+0+2+40+1.65+1.65+0+0.5%0Af+880+400+928+400+32+1.5+0.02%0Ar+752+400+880+400+0+500%0Ag+928+416+928+432+0%0AR+928+224+928+176+0+0+40+3.3+0+0+0.5%0Ar+928+224+928+288+0+220%0A162+928+288+928+384+2+default-led+1+0+0+0.01%0A
Sep 04 00:17:23 <set_> Yep. I just looked it up.
Sep 04 00:17:23 <set_> Nice!
Sep 04 00:17:23 <mawk> why 5V ? you can use 3.3V
Sep 04 00:17:23 <mawk> otherwise it's more complicated
Sep 04 00:17:36 <set_> Oh.
Sep 04 00:17:48 <mawk> or maybe not actually
Sep 04 00:17:54 <set_> I think since I can drain up to 400 mA, it is okay.
Sep 04 00:17:54 <mawk> you can use 5V on the LED side sure
Sep 04 00:18:19 <mawk> yes it doesn't really matter as long as you can push enough current through the LED and overcome it's polarization voltage
Sep 04 00:18:27 <mawk> eg 3.0V for blue leds I think
Sep 04 00:18:40 <set_> I have a yellow one.
Sep 04 00:18:44 <mawk> actually my circuit is bad
Sep 04 00:18:47 <set_> Oh?
Sep 04 00:18:50 <mawk> yeah, you should have a datasheet for it
Sep 04 00:19:02 <set_> I was wondering about the 500 ohm resistor.
Sep 04 00:19:07 <set_> I have one.
Sep 04 00:20:20 <set_> So, GND to source to drain to LED!
Sep 04 00:20:33 <set_> Then, LED anode to resistor.
Sep 04 00:20:53 <set_> Then, resistor to the sys_5v.
Sep 04 00:21:32 <set_> the bs270 is d, g, then s. Right?
Sep 04 00:21:45 <set_> I guess it is a bit hard to describe w/out visuals.
Sep 04 00:22:52 <mawk> the ground doesn't go to souce
Sep 04 00:22:53 <mawk> source
Sep 04 00:23:01 <set_> Oh.
Sep 04 00:24:27 <mawk> actually my circuit seems fine
Sep 04 00:24:30 <set_> Okay.
Sep 04 00:25:19 <set_> Yea.
Sep 04 00:25:29 <set_> The circuit is the same as mine but different.
Sep 04 00:26:05 <set_> The middle pin is G and not S, right?
Sep 04 00:26:16 <set_> The photo in the datasheet is a bit off.
Sep 04 00:28:52 <mawk> the pin in the middle is G
Sep 04 00:28:54 <mawk> yes
Sep 04 00:28:57 <mawk> D, G, S
Sep 04 00:29:03 <mawk> when the flat side is towards you
Sep 04 00:29:25 <mawk> use a resistor to the gate, it's always safety practice when you're not extra sure what you're doing
Sep 04 00:29:27 <mawk> like 1K
Sep 04 00:29:37 <set_> Okay. I see the diagram next to the photo. Yea. the center pin is G and not S.
Sep 04 00:29:38 <mawk> 1K means slow startup time, but it doesn't matter here your here won't notice
Sep 04 00:29:56 <mawk> your eyes won't notice*
**** BEGIN LOGGING AT Wed Sep 04 01:07:28 2019
Sep 04 02:31:31 <set_> Okay.
Sep 04 02:59:47 <set_> The FET is in business!
