[0:02] <NineChickens> Anyone remember how a couple of weeks ago I said that my school's server was down due to a power surge?
[0:02] <IanTLopp> nope.. don't remember at all
[0:04] <NineChickens> There was a gig I was discussing it with
[0:05] <NineChickens> Anyway, the surge came from a faulty UPS
[0:05] <NineChickens> Happened to walk past the server cabinet today
[0:05] <NineChickens> *beep* *beep* *beep*
[0:06] <plm> Any news about pi zero w to buy in high quantity?
[0:06] <IanTLopp> plm: if you find out, let me know okay? I need more than the 2 a week I can manage.
[0:09] <NineChickens> What country?
[0:09] <IanTLopp> US here

[0:10] <Rukus> omg
[0:10] <Rukus> i'm sorry
[0:10] <Rukus> i was googling because i was curious and didnt mean to paste that here
[0:10] <Rukus> i'm having a bad day
[0:11] <IanTLopp> hehe.
[0:11] <IanTLopp> $28.51 each. worse than amazon
[0:11] <Rukus> lol yeah
[0:11] <Rukus> but looks like they could supply haha
[0:12] <IanTLopp> up to 197
[0:13] <oq> if they're not fakes they would be importing them from wales all the way to china to then export them back to you
[0:14] <Rukus> pi boards are made in china too
[0:14] <oq> pi0's are all made in sony factory in wales
[0:14] <IanTLopp> everything's made in china
[0:14] <Rukus> i mean authentic pi 3 boards at least
[0:14] <oq> the pi0's are different because it's not outsourced to farnel
[0:14] <Rukus> pi 2/3
[0:15] <Rukus> i didnt know that
[0:15] <Rukus> oq alixpress isn't only for china sellers
[0:15] <oq> Rukus: why would a non-chinese use aliexpress lol
[0:16] <Rukus> but the brand name says unistorm
[0:16] <Rukus> so whatever that is
[0:16] <IanTLopp> since they don't have a manufacturer's supply (they have more of a warehouse style supply) I'd say they're just buying them, and reselling them.
[0:16] * Mikelevel (~MoVeWoRk@unaffiliated/mikelevel) Quit (Ping timeout: 256 seconds)
[0:17] <Rukus> perhaps
[0:17] <Rukus> i know that a lot of "factories" in china are just warehouses
[0:17] <Rukus> especially when buying from alibaba / aliexpress
[0:20] <CuSn> oq: same reason a lot of vendors use Amazon as a place to list their wares: traffic.
[0:21] <remote> does anyone know what kind of device uses magnetic coil?
[0:21] <brianx> remote: an inductor.
[0:21] <IanTLopp> mcd's
[0:21] <CuSn> disk drives, some solenoids, some relays
[0:21] <IanTLopp> damn it.. I was trying to make one joke, and then McDonald's rears its ugly head.
[0:22] <remote> i'm electronically-illeterate and trying to hack hardware around the house
[0:22] <remote> ^ that's to say idk what uses inductors
[0:22] <remote> CuSn: thanks that could get me something
[0:22] <CuSn> some remote door locks
[0:22] <remote> old harddrives
[0:23] * CuSn is grateful no one anything about moms.
[0:23] <remote> hey
[0:23] <brianx> remote: the most common use of inductors around the house would be power supplies.
[0:23] <remote> hmm...
[0:23] <IanTLopp> CuSn, what about moms?
[0:23] <remote> not powerbars rght?
[0:23] <remote> also, I was about to ask: what makes a device use larger (AWG) coil than others?
[0:23] <CuSn> IanTLopp: No one said anything about them.
[0:24] <IanTLopp> CuSn, well now I'm asking... what are moms?
[0:24] <IanTLopp> are moms hot?
[0:24] <remote> oh powersupply! I do have at least an old one
[0:25] <remote> sorry for taking over the conversation (and I'm done) -- nobody sems to like #hardware for some reason
[0:25] * rikk (~rikk@unaffiliated/rikk) has joined #raspberrypi
[0:28] <Rukus> will the raspberry pi use videocore iv in upcoming boards?
[0:28] * Mikelevel (~MoVeWoRk@unaffiliated/mikelevel) has joined #raspberrypi
[0:29] <Rukus> or better yet, would that be likely?
[0:29] <ShorTie> nobody knows
[0:29] <brianx> remote: larger awg wire in an inductor is used to handle more current.
[0:30] <remote> brianx: thanks!

[0:57] <[Saint]> I was wondering:
[0:57] <[Saint]> What, if any, external DAC/audio card do you guys use? Why? And how do you find it?
[0:57] <oq> I use a cheap one I found on amazon
[0:57] <[Saint]> Especially interested in comments from those with multiple hardware solutions with regard to why they are using their current configuration.
[0:58] * IT_Sean (~quassel@applefritter/IRCStaff) Quit (Remote host closed the connection)
[0:58] <HrdwrBoB> I found a cheap one
[0:58] <HrdwrBoB> it was A+
[0:58] <[Saint]> I use the Cirrus Logic Audio Card on my Raspberry Pi Model B 3 boards, and the Wolfson Audio Card on my older model Pi boards.
[0:58] <oq> and it just plugs into the usb dock on my desk, much simplier cable wise
[0:58] <HrdwrBoB> can't even remember
[0:59] <[Saint]> AH, so you're both using USB DACs, as opposed to Pi HAT configuration boards?
[1:00] <ali1234> i have a pi digi amp+
[1:00] <ali1234> it's fine i guess, i dunno
[1:00] * mmazing (~mmazing@unaffiliated/mmazing) Quit (Quit: Leaving)
[1:00] <[Saint]> I like the Cirrus Logic (formerly Wolfson) Audio Cards as they have an absolutely foolish maximum sample rate and configurable high and low shelf filtering.
[1:00] <[Saint]> As well as active cancellation so it prevents the horrid pop/thump when waking up an external amplifier/source.
[1:01] * teepee (~teepee@unaffiliated/teepee) has joined #raspberrypi
[1:01] <[Saint]> But I'm curious about other devices.
[1:01] <[Saint]> I had a Digi+ board, but I never actually got the chance to use it.
[1:02] <[Saint]> Because they shipped me two boards that were DOA, and instead of offering to risk a third replacement board I just got them to credit the funds back to my debit account.
[1:02] <[Saint]> I'm not sure if it was crappy manufacturing, if if they got mistreated during shipping.
[1:03] <[Saint]> But neither of them would power up straight out of the box.
[1:03] * exobuzz (~buzz@cpc69064-oxfd26-2-0-cust48.4-3.cable.virginm.net) has joined #raspberrypi
[1:03] <[Saint]> WHich I was mildly disappointed about as generally speaking I hear good things about the HifiBerry boards.
[1:03] * vstehle (~vstehle@rqp06-1-88-178-86-202.fbx.proxad.net) Quit (Ping timeout: 260 seconds)
[1:03] * dreamon (~dreamon@unaffiliated/dreamon) has joined #raspberrypi
[1:04] <[Saint]> I set up a couple of boxes for other people with HiFiBerry amps of various models, but I don't have extensive knowledge of them nor much experience in their useage barring setting them up for customers.

[1:33] <Rukus> [Saint]: whats a good solution for added optical ?
[1:34] <[Saint]> Rukus: HiFiBerry Digi+
[1:34] <Rukus> ok, sweet i am going to look into that
[1:35] <Rukus> thanks!
[1:35] <[Saint]> I happen to know that because I've set up several media boxes for clients that required optical out to components.
[1:35] <[Saint]> ...it's not cheap.
[1:35] <[Saint]> I'll say that much.
[1:35] <Rukus> i currently passthrough HDMI and optical out from my TV
[1:35] <Rukus> maybe its sufficient
[1:35] <[Saint]> What media platform do you use? Or do you use a general purpose operating system?
[1:36] <Rukus> osmc
[1:36] <[Saint]> I pretty highly recommend LibreELEC, but I'm biased as a contributor.
[1:36] <Rukus> i understand
[1:36] * GrimKriegor (~GrimKrieg@ Quit (Read error: Connection reset by peer)
[1:36] <Rukus> I've grown fond of osmc because of its versatility
[1:37] <[Saint]> If you need additional full-distribution-like functionality, I recommend using PINN (a NOOBS fork) and dualbooting between Raspbian Lite w/ PIXEL and LibreELEC.
[1:37] <Rukus> thanks! never heard of PINN
[1:37] <[Saint]> Though I'll note that LibreELEC has a suite of add-ons and full Docker container support.
[1:37] <Rukus> last time i tried libreelec was over 6 months ago
[1:37] * swift110 (~swift110@unaffiliated/swift110) Quit (Ping timeout: 256 seconds)
[1:38] <[Saint]> PINN is NOOBS but with a few value added features, like disk cloning, external storage support, and CEC control.
[1:38] * GrimKriegor (~GrimKrieg@ has joined #raspberrypi
[1:38] <Rukus> oh nice
[1:38] <[Saint]> also a suite of additional wireless firmware embedded.
[1:38] <Rukus> thats the bonus there
[1:38] <[Saint]> I use PINN so that I can dual-boot and not have to get my lazy ass up off the couch.
[1:38] <Rukus> i had to make a router into a wireless bridge last time. because my second media centre is in my bedroom
[1:38] <koss> will this work in pi3? http://www.amazon.com/exec/obidos/ASIN/B01IC0GJKE/fpv-20/
[1:39] <[Saint]> just use HDMI CEC control to switch dual-boot images.
[1:39] <Rukus> thats awesome
[1:39] <[Saint]> koss: Yes.
[1:39] <Rukus> i dont know what docker containers are
[1:39] <[Saint]> Rukus: if you do end up trying out LibreELEC, make sure to use the LE18 Raspberrypi testbuilds.
[1:40] <Rukus> i have to redo my bedroom setup, so i might just do that!
[1:40] <[Saint]> They're bleeding edge, but the rpi optimization is extensive, and it's based on Kodi 18.
[1:40] * webturtle0 (~webturtle@ has joined #raspberrypi
[1:40] <Rukus> i should write this down
[1:40] <[Saint]> http://forum.kodi.tv/showthread.php?tid=298461
[1:40] <[Saint]> that's the LE18 testbuild thread.
[1:41] <[Saint]> You need to start off from an official LE release.
[1:41] <Rukus> then upgrade from that?
[1:41] <[Saint]> Installation/updating is covered in the first post of that thread.
[1:41] <Rukus> ok
[1:41] <[Saint]> This is PINN:
[1:41] <[Saint]> https://github.com/procount/pinn
[1:41] <[Saint]> installation and download/instructions covered therein.
[1:42] <Rukus> whats the sweet
[1:42] <Rukus> err
[1:42] <Rukus> sweet
[1:42] <[Saint]> With the LE18 Rpi3 testbuilds, you can even decode H.265
[1:42] <Rukus> oh right, whats the cliff notes on why i might want le over osmc?
[1:43] <Rukus> is that with overlock?
[1:43] <[Saint]> No.
[1:43] <Rukus> omg
[1:43] <Rukus> *drools*
[1:43] <Rukus> i do H.265 but with overclock
[1:43] <[Saint]> Though a mild SDRAM and ARM overclock is recommended.
[1:43] * Viper168 (~Viper@unaffiliated/viper168) Quit (Ping timeout: 260 seconds)
[1:43] <Rukus> i'm rocking 1360, 580 sdram
[1:44] <[Saint]> With LE18 you should be able to decode most H.265/20 content.
[1:44] <[Saint]> with that overclock, you'll /maybe/ be able to do H.265/30 reliably.
[1:44] <Rukus> H.265/20 ? wahts the 20?
[1:44] <Rukus> fps?
[1:44] <[Saint]> framerate
[1:44] <Rukus> oh ok
[1:44] <Rukus> 24 is my only requirement
[1:44] <Rukus> 23.976 to be exact
[1:45] <[Saint]> Yeah, with that overclock, you'll be able to get away with it unless it's been transcoded or framepacked weird.
[1:45] <Rukus> so how is this possible with nay overclock?
[1:45] * webturtle0 (~webturtle@ Quit (Ping timeout: 256 seconds)
[1:45] * Viper168 (~Viper@unaffiliated/viper168) has joined #raspberrypi
[1:45] <[Saint]> I run 1450 ARM, 550 GPU, and 600 SDRAM myself.
[1:46] <Rukus> how did you get to 1450?
[1:46] <[Saint]> with sdhost clocked at 100MHz
[1:46] <Rukus> i might need some more pointers
[1:46] * qdk (~qdk@xd520f2e4.cust.hiper.dk) Quit (Ping timeout: 268 seconds)
[1:46] <Rukus> yeah my sdhost is 100mhz too, i managed 45read / 40~ write
[1:46] <[Saint]> Just lucky I guess. Most of my units reliably do 1400, but I only have a couple that do above 1400.
[1:46] <Rukus> MB/sec
[1:47] <Rukus> if i go above 1360, osmc breaks
[1:47] <[Saint]> Same with SDRAM, all of my units do 550MHz SDRAM, but only a couple of them do 600MHz
[1:47] <Rukus> i can do 588 for sure
[1:47] <Rukus> on sdram
[1:47] <Rukus> havnt tried further
[1:48] <Rukus> thanks for all this great info, you might have gave me something to do again
[1:48] <Rukus> my wife will be pleased!
[1:48] <Rukus> bahaha
[1:48] <[Saint]> Hahaha
[1:48] <[Saint]> Happy to help.
[1:48] <Rukus> Do you have heatsinks installed?
[1:49] <Rukus> i just put somne stick on aluminums
[1:49] <Rukus> and probably not all the places they need to be
[1:49] <[Saint]> Nope. FOr a passive heatsink to have any actual value it needs to be about the size of your fist.
[1:49] <Rukus> one on arm, other on ethernet
[1:49] <Rukus> oh no way
[1:49] <Rukus> and theres a fan
[1:49] <[Saint]> If they're not actively cooled, they're just "go-fast-bits" that look cool.
[1:50] <Rukus> how did you manage your voltages at those clock speeds?
[1:50] <[Saint]> I don't bother about cooling because even at those clocks I only very rarely break 85C.
[1:50] <Rukus> Ive never gone past 65C on my overclock
[1:51] <Rukus> but, i have a fan on it and who knows how that affects the reading
[1:51] <[Saint]> arm/gpu overvolt of 6, sdram overvolt of 6, 4, 4
[1:51] <Rukus> doesnt the ram on a pi 3 overlock with only one value?
[1:51] <Rukus> thats never been clear
[1:51] <Rukus> (to me)
[1:52] * gugah (~gugah@ Quit (Ping timeout: 264 seconds)
[1:52] <[Saint]> Yes, and no. There's a single value to control all the paramaters (similar to GPU), or individual values to control them separately.
[1:52] * semyon (~semyon@unaffiliated/semyon) Quit (Quit: Going offline, see ya! (www.adiirc.com))
[1:53] <[Saint]> You could just as easily overvolt sdram globally to 6.
[1:53] <[Saint]> But I don't overvolt anything I don't absolutely have to to get the desired function.
[1:53] * Hix (~hix@97e7179f.skybroadband.com) Quit (Remote host closed the connection)
[1:53] <[Saint]> And 6, 4, 4 is fine for me with sdram schmoo
[1:54] <Rukus> arm_freq=1360 gpu_freq=500 core_freq=500 over_voltage=4
[1:54] <Rukus> thats what i found
[1:54] <Rukus> to work for me, but i always wanted to squeeze more
[1:54] * Feedz (~Feedz@unaffiliated/feedz) Quit (Remote host closed the connection)
[1:54] * Mikelevel (~MoVeWoRk@unaffiliated/mikelevel) Quit (Remote host closed the connection)
[1:54] <[Saint]> this is explained very clearly in the rpi configuration documentation.
[1:55] <[Saint]> no need to guess function from random contextless internet blog or forum postings.
[1:55] <Rukus> i've had a bit o a read, but get confused if pi1 = pi2 = pi3
[1:55] <Rukus> for certain settings
[1:55] <Rukus> #Ram Overlock Settings sdram_freq=580 sdram_schmoo=0x02000020 over_voltage_sdram=
[1:56] <[Saint]> for these purposes, pi3 == pi2
[1:56] <Rukus> 2
[1:56] <Rukus> i use waaaay lower voltage than you
[1:56] <Rukus> hmmm
[1:56] <[Saint]> that's a VERY lor SDRAM overvolt for that SDRAM frequency.
[1:56] <[Saint]> *low
[1:56] <Rukus> that could be my instability issues
[1:56] <[Saint]> I would not be surprised if you get reboots or Kodi restarts all over the place.
[1:56] <Rukus> i meant when i push arm further
[1:57] <Rukus> nah i dont
[1:57] <[Saint]> Oh, hah, snap.
[1:57] <Rukus> its rock solid
[1:57] <[Saint]> That's...interesting.
[1:57] <[Saint]> Probably why you can't hit 600 though.
[1:57] <Rukus> unless i try to clock arm faster than 1380
[1:57] <Rukus> i havnt tried
[1:57] <[Saint]> Oh. Weird. Why?
[1:57] <[Saint]> First thing I do with any given unit is see what legs I can get out of it.
[1:57] <[Saint]> They're pretty forgiving.
[1:58] <Rukus> dunno, it plays shows like big bang theory on H.265, but something with more action it stutters, but a watchable stutter
[1:58] <Rukus> like, a scene that has a lot going on
[1:58] <Rukus> like moving water at the beginning of vikings
[1:58] <[Saint]> Yeah, the issue there is SDRAM literally can't keep up.
[1:59] <Rukus> this is really interesting tbh!
[1:59] <[Saint]> increasing SDRAM clock has the largest single effect on H.265 playback, without getting into territory of increasing H.265 decode efficiency.
[1:59] * qdk (~qdk@xd520f2ba.cust.hiper.dk) has joined #raspberrypi
[1:59] <[Saint]> (which LE is doing, care of the absolute machine that is popcornmix)
[2:00] <Rukus> that was what i noticed when i backed off my sdram to 500
[2:00] <Rukus> hmm...
[2:00] <Rukus> I'm going to try your settings
[2:00] <Rukus> but on LE\
[2:00] <Rukus> i dont think osmc is very forgiving
[2:01] * de-facto (~de-facto@gateway/tor-sasl/de-facto) Quit (Quit: See you around.)
[2:01] * de-facto (~de-facto@gateway/tor-sasl/de-facto) has joined #raspberrypi
[2:01] <[Saint]> I don't think OSMC has the bleeding edge firmware to be able to manage most of this.
[2:01] <[Saint]> It will eventually trickle down into OSMC, one supposes.
[2:01] <[Saint]> But LE 18 for the Rpi is _absolute bleeding edge_.
[2:02] <Rukus> I had no idea
[2:02] <[Saint]> It's at a point know where the rest of us already did the hard yards on testing and it's stable enough for Joe Everday.
[2:02] <[Saint]> s/know/now/
[2:02] <Rukus> well I know what I am doing tomorrow
[2:02] <[Saint]> :)
[2:02] <[Saint]> Just bookmark the link(s) I gave you above. You'll be right.
[2:02] <Rukus> hope you'll be around, id love to share my findings with you
[2:03] <[Saint]> My client is always around unless my Internet falls over. I'm usually not too far away.
[2:03] <Rukus> sweet
[2:03] <Rukus> is this the proper way to overlock sdhost?
[2:04] <Rukus> #SDCard Overclock
[2:04] <Rukus> dtparam=sd_overclock=100
[2:04] <Rukus> overclock*
[2:04] <[Saint]> My client will tell you if I'm away, away away, or away away away. lol.
[2:04] <[Saint]> as in away set. away set from idle. or away set from no clients(s) being connected to the distributed IRC backend.
[2:04] <[Saint]> Yes. It is.
[2:04] <Rukus> ok sweet
[2:04] <Rukus> and is this as necessary as i rthink it is?
[2:04] <Rukus> #Miscellaneous important for overlock
[2:04] <Rukus> force_turbo=1
[2:04] <Rukus> boot_delay=1
[2:05] <Rukus> i dont care about warranty

[2:05] <Rukus> i always misspell overclock
[2:06] <[Saint]> force_turbo isn't necessary at all, but it can increase boot times.
[2:06] <[Saint]> boot_delay=1 is a bit of a weird one, as that's superfluous. 1 is the default value anyway, so that's not actually doing anything.
[2:06] <Rukus> oh
[2:06] <Rukus> this is great
[2:06] <Rukus> I'm gonna have such a pimped out system
[2:06] <[Saint]> boot_delay can be required if you overclock the sdhost, as it gives the card some time to initialize, or "warm up" if you will, before jumping on it with a high clock.
[2:07] <Rukus> ah got ya
[2:07] <[Saint]> But given that you've seen zero issues from it so far...seems that, in your case, it's not.
[2:07] <[Saint]> You'd know if you needed it because you'd be regularly corrupting your filesystem.

[2:10] <Rukus> that will be awesome for my living room setup. However, I bought a Mele F10 Deluxe
[2:10] <[Saint]> Oh, Rukus, one thing you may or may not care for and another point for the LibreELEC camp is that LibreELEC 18 includes libretro/RetroArch core integration.
[2:10] <[Saint]> Which is a longwinded way of saying that you get baked in retrogaming emulation.
[2:10] <Rukus> nice!
[2:11] <Rukus> how could i know if my file system is corrupted?
[2:11] <Rukus> ive only been about 2 to 3 weeks on this sdhost overclock

[2:12] <Rukus> the only strange things i saw was, some blocking on my screen, but that was when i found myself on kind of an inbetween update between osmc RC1 and official
[2:12] <[Saint]> To enable the libretro/retroarch cores in the LE18 testbuilds, you simply plug in the Konami code from an attached keyboard while in the main menu.
[2:12] <Rukus> thats cool, i love the konami code

[3:25] <[Saint]> the whole "have to be root" for $THING is almost universally untrue.
[3:25] <brianx> [Saint]: that permission only applies to the kernel, not to direct hardware access.

[3:28] <pksadiq> the pi user is already in spi group, and I can read spi continuesly. But it takes about 100% CPU in a while loop. I wish it would wait on 'read' when the buffer is empty. Instead, it simply prints 0 continuesly until some data is recieved.
[3:28] <[Saint]> If one can use i2c without root, and if one can use transitional libraries to use SPI and friends without root...
[3:28] <[Saint]> I don't see any reason as to why you couldn't do so.
[3:29] <pksadiq> I can read spi (/dev/spidevx.x) without being root. The issue is, it doesn't care whether there is a data in buffer or not.
[3:29] <[Saint]> I'm pretty confident the whole "need to be root" thing is categorically untrue, just not around actual hardware or not.
[3:29] <[Saint]> pksadiq: yeah, right - I'm kinda having a discussion with myself, or kinda vaguely talking /at/ brianx
[3:30] <[Saint]> the whole issue of root as opposed to sane group and permission managament thing pisses me off in general.
[3:30] <brianx> [Saint]: if you use the kernel driver, you are correct.
[3:31] <brianx> if you do direct hardware access, bypassing the kernel, you must have root. that applies to gpio, i2s, spi, serial, everything.
[3:31] <brianx> pksadiq specified an interrupt and not a callback, so that's direct hardware and bypassing the kernel.

[3:32] <pksadiq> brianx: I'm okay to have any way (It should be doable in C). But it shouldn't cause much CPU usage, and read only when there is data. Also, I should be able to not run as root.
[3:32] <brianx> "standard calls" would be through the kernel and permissions do apply.
[3:33] <[Saint]> yeah, I'm aware. It was kinda talking at myself, self-confirmation.
[3:33] <brianx> pksadiq: then i would suggest getting a callback and not an interrupt. i've never touched spi through the kernel so will defer to [Saint] on that.
[3:33] <[Saint]> Though FWIW I don't really see why you wouldn't opt to use standard calls here.
[3:34] <brianx> [Saint], i agree.
[3:34] <brianx> going through the kernel is the better approach, though more complex and slower.

[6:35] <IanTLopp> and do you want a hub, or just a charger?
[6:36] <nevodka> for charging i mean, three pi 3 B's and a pi 1 b+ i believe
[6:36] <nevodka> i have one of these https://www.amazon.com/gp/product/B00JX1ZS5O/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

[12:58] <python476> not hat, more a cap
[12:59] <BurtyB> usb stem vs usb hub are for totally different uses...

[12:59] <Duckle|wasDumle> oh it's a male usb
[12:59] <Duckle|wasDumle> nvm
[12:59] <shauno> very different. a hub blocks the use of otg, the stem seems entirely designed for otg
[12:59] <BurtyB> except it's not a proper hat ;)
[12:59] <password4> nice pogo pins in that one
[13:00] <Duckle|wasDumle> I thought I saw a female plug :) Thought it just broke out the otg to a host connector :)

[13:06] <password4> Duckle|wasDumle: you are the one claiming not to believe me :O
[13:07] <password4> also i did not say anything less family friendly than the tone of the conversation
[13:07] <Duckle|wasDumle> uhm, you're the one claiming that they were built specifically for strenght improvement, I'm claiming it's just the logical progression of miniturisation

[15:31] <Sonny_Jim> https://www.facebook.com/matthew.t.read/videos/10212905242292618/
[15:31] <Eduard_Munteanu> Is there a video codec that has decent performance on RPi using only software decoding?
[15:32] <Eduard_Munteanu> Let's say 1080p.
[15:32] <Sonny_Jim> Well, x624 seems to be just fine and dandy
[15:32] <gordonDrogon> Sonny_Jim, neat. (although I don't really know what call of duty is other than a game)
[15:33] <Sonny_Jim> Me neither, I tuned out of First Person Shooters just after Quake 3: Arena. Shooting cartoon monsters is one thing, accurately recreating horrific WW2 battles is another
[15:33] <Eduard_Munteanu> Sonny_Jim, hm, really? I should try it, but I'm a bit skeptical it delivers smooth video.

[15:34] <Sonny_Jim> Eduard_Munteanu: That's what I throw at Kodi and it plays ok, so go figure. I believe x265 is possible with a very small purchase of a codec
[15:34] <Sonny_Jim> it's like $3 or something like that
[15:35] <oq> Eduard_Munteanu: the pi is a mobile phone soc, no way it can ever decode 1080p in software smoothly
[15:35] <Eduard_Munteanu> I see.
[15:35] <Sonny_Jim> It's a lot of pixels to be pushing around
[15:35] <Sonny_Jim> There's hardware decoders that come for free though
[15:35] <Sonny_Jim> Not sure why you'd want to force yourself into using a software decoder
[15:36] <Eduard_Munteanu> I could use VLC, but IIRC its decoder was kinda buggy.
[15:36] <Eduard_Munteanu> And I have to recompile VLC under Raspbian and all that.
[15:36] <Sonny_Jim> omxplayer does just fine
[15:37] <Sonny_Jim> Must be a GUI version around somewhere but I've never really needed it
[15:37] <Eduard_Munteanu> omxplayer isn't a library, I need to integrate it with my own app.
[15:37] <Sonny_Jim> Call it as an external binary
[15:37] <Sonny_Jim> It's messy but it'll work
[15:37] <Sonny_Jim> Kodi does use it as it's player and overlays onto it, so maybe have a look at that

[17:07] <codepython777> IT_Sean: any pointers on how to do this?
[17:08] <IT_Sean> you would need to find a fan controller or something to vary the voltage to the fan, perhaps based on a PWM signal from the Pi.
[17:08] <IT_Sean> That's about as far as my thinking takes me.

[19:02] <jamesaxl> gordonDrogon, what do you use then?
[19:02] <brianx> i just had the solution to one small module in his overall system.
[19:03] * Vonter (~Vonter@ Quit (Remote host closed the connection)
[19:03] <gordonDrogon> jamesaxl, I program mostly in BASIC or C.
[19:04] <brianx> i decided that i didn't want anything as complex as a pi at the core of my home automation. it's fine for logging and user interface, but i want the systems to keep working even if linux fails.
[19:05] <Psi-Jack> I do a lot of python, which is one reason I went the RPi route because apparently has really good GPIO control already developed for python for the pi.
[19:05] <jamesaxl> gordonDrogon, I like C :), do you have an advice in C about my problem ?
[19:05] <brianx> and the author of it is right here.
[19:06] <Gadgetoid> Yeah, C google... hahaha sorry :(
[19:06] <gordonDrogon> I'm working on some small factory type automation - it's mostly small autonomous units with ATmegas with a Pi (or 2) at the middle which can monitor and dispatch commands.

[19:07] <brianx> Psi-Jack: not me, gordonDrogon wrote it.
[19:07] <Psi-Jack> Oh! Well, awesome.
[19:08] <brianx> iirc, he didn't do the python side, but he wrote the code that the python api uses.
[19:08] <Psi-Jack> Ahhh. Yeah. :)
[19:08] <gordonDrogon> jamesaxl, I've used these devices, (hc sr-04) but only on ATmegas. the documentation is fairly straightforward from what I remember - tiggle the pin line, then wait for the input to signal, measure the time and distance = time / speed of sound.

[19:09] <yellabs-r2> sorry was reading along with you, in this autonomous setup with the pi, how do you power down these devices ? Hard shutdown seems to be an awful way ( turn off usb current ) have you come up wathc an other solution ?
[19:09] <gordonDrogon> I write and maintain wiringPi (which is a GPIO library written in C for C/C++ and BASIC programs) I also wrote my own BASIC interperter (in C). Others have ported wiringPi to other languages ...

[19:12] <jamesaxl> gordonDrogon, it works good with ATmega
[19:12] <brianx> yellabs-r2: like any linux, init 0 works. you can pull power after that completes.
[19:13] <yellabs-r2> ok ..
[19:14] <gordonDrogon> halt is even quicker to type. that's what I do when I get the chance if I have to power down a Pi.
[19:14] <gordonDrogon> jamesaxl, you ought to be able to take the atmega code and just compile it on the Pi - if you link with wiringPi then you have pinMode(), digitalRead() and digitalWrite(), etc.
[19:15] <brianx> i stick to the (nearly) universal command so i don't have to think about it, but there are several choices.

[19:36] <brianx> Psi-Jack: is the code open source? didn't think it was but didn't look.
[19:37] <Psi-Jack> Well, I believe it's more java than anything. So it has a chance of working at least.
[19:37] <Psi-Jack> I don't think it's opensource though, no.
[19:38] <brianx> gordonDrogon: pulling the shelves kinda defeats automating, unless you already have that on a motor.

[19:40] <Psi-Jack> Yeah, I just got two UAP-AC-Lites for my house, and wow.... Best WiFi I've ever had in my home.
[19:41] <brianx> Psi-Jack: i decided on the LR version.
[19:41] <Psi-Jack> If the Pi can run it, I'll just get a Pi to run that. but if not, I'll likely get a pcengines.ch system to run it. :)
[19:41] <Psi-Jack> brianx: I decided against the LR version because the majority of my devices are mobile devices, like cell phones, which may be able to receive the LR from the AP, but not have the strength to push replies back.
[19:42] <Psi-Jack> So for me, it was either the Lite, or the Pro, and the Lite's were half the cost of the Pros.

[21:15] <Duckle|wasDumle> Hey there. Anyone in here who might be able to help me troubleshoot an issue I'm having with some software? In particular UV4L-server

[21:15] <Duckle|wasDumle> and I can't find any log output to get hints at what's going wrong
[21:18] <brianx> Psi-Jack: cool. so you can run it from anything that puts out enough watts at anything from 10V to 48V. if you're at the low end, of course you have to account for voltage drop due to cable resistance, so 12V might be a more practical bottom end.
[21:18] <Psi-Jack> Heh yeah.
[21:18] <Psi-Jack> I'm actualy calculating how plausible that is now with Cat6 cabling.
[21:19] <brianx> in my case, i want to power from a battery for backup.
[21:20] <Psi-Jack> Heh, I already have that with the APC.
[21:20] <brianx> i try to stay away from that brand after experiencing many units failing the same way.
[21:21] * swift110 (~swift110@unaffiliated/swift110) Quit (Ping timeout: 258 seconds)
[21:21] <brianx> a short power glitch would trigger the cutover but when the timing was just right, the cutover would abort in the middle leaving both mains and battery power off.
[21:22] <Psi-Jack> Yeah. Cat6 23AWG or 24AWG will be just fine for pushing 24V over 50~100ft with still 22V remaining.
[21:22] <de-facto> That PIXEL desktop is really nice, are there any dark themes available e.g. that would color match gnome adwaita dark colored themes?
[21:22] <brianx> we had really dirty power so this would happen about once a month, "protected" machines would shut down, machines with no battery backup at all would continue running as if nothing happened.
[21:22] <Psi-Jack> brianx: Hmm, odd. The only problem I've had is dying batteries.
[21:23] <Psi-Jack> Batteries that mostly have been fully charged and never drained, no less, just dying. heh
[21:23] <brianx> we had dozens of APC that i inherited. it took me about a year to convince the powers that be to switch to a better brand. (at twice the cost)
[21:24] <Psi-Jack> heh. What's the better brand?
[21:24] <brianx> i wish i could remember. they're out of business though.
[21:24] <Psi-Jack> Ahh
[21:24] <brianx> sola i think.
[21:24] <brianx> made about 2 blocks from here.
[21:25] <Psi-Jack> Interesting.
[21:25] <brianx> it's now a self storage.
[21:25] <Psi-Jack> Yeah, currently I have 2 APC batteries dead. One's still in use just gives a few seconds of power on almost no draw, and it stops.
[21:25] <brianx> it looks like they still exist. maybe made by emerson.
[21:25] <Psi-Jack> Oh.. emerson. ewww.
[21:26] <Psi-Jack> I've brushed my feet permanently of emerson.

[21:28] <brianx> emerson sold off their consumer product line to thompson decades ago, but they still make good industrial stuff. looks like the industrial people still make a sola line.
[21:29] <Psi-Jack> hmmm.. I see nothing about Emerson Thompson on google.
[21:30] <brianx> thompson is the people who bought rca tvs and ge small appliances and black n decker and a zillion other good old names and drove them all into the ground.
[21:31] <Psi-Jack> But, ultimately, they still stamp their products as Emerson, same logo and all.
[21:31] <Psi-Jack> Ahhh.. THAT's why Black & Decker went to crap, RCA too.
[21:31] <Psi-Jack> No wonder!
[21:32] <brianx> yep. they had headquarters in indiana (not sure if that's current) but offshored everything. this was mostly before offshore was even popular.
[21:33] <brianx> sorry, US headquarters. french company.
[21:33] <Psi-Jack> Huh.. Wierd.. Emerson Radio, the actual name we're talking about, was owned by Panasonic, but sold to Funai in 2001.
[21:33] <Psi-Jack> But yep. Hackensack, NJ
[21:34] <brianx> yeah, emerson radio is another company too.

[22:56] <NineChickens> Thing is, I'm using my Raspbian w/o desktop SD so I used my web browser on my laptop
[22:56] <NineChickens> so LocalSettings.php does not automatically download to the pi
[22:57] <Rukus> sometimes the simplest answer works. remove the sdcard, insert in ps, copy over file, put it where it goes?

[23:00] * ttyS2 (~Username@ has left #raspberrypi
[23:00] <Rukus> well, maybe i am misunderstanding your constraints?

[23:00] <Rukus> there. listen to shauno. problem solved
[23:01] <shauno> oh I'd whack the card into a computer for a few moments too. just .. this is gonna come back again and again. when you try to upload a skin for MW, extensions, etc etc

[23:09] <NineChickens> Quick question or two-hostapd.conf is the one that manages wifi and stuff on the pi, right?
[23:09] <shauno> like the wikitext renderer in MW is near-impossible to fully duplicate, because it does so many things that weren't actually by design. they just are because they always have been
[23:09] <NineChickens> lol
[23:10] <NineChickens> also on my desk I now have two routers and two wireless access points

[23:14] <shauno> and fwiw, I think I only single php out because I've had to deal with wordpress and mediawiki in the same weekend :/
[23:16] <NineChickens> anyway, I stuck the SD card that had images on it into the pi
[23:17] <NineChickens> not raspbian

[23:29] <Rukus> I bought a HooToo router, and it stopped working (maybe my fault, i dont know) and they are mailing me a replacement under warranty no questions asked
[23:29] * Grapes (~greatgrap@ has joined #raspberrypi
[23:30] <NineChickens> It's all stuff the tech department threw out
[23:30] <NineChickens> IT didn't want it
[23:30] <Rukus> HooToo stuff is inexpensive and fairly useful. just sharin

[23:45] <shauno> I think our guys would prefer if I just used netgear stuff to break the network. I threw in a spare cisco switch once, and they started .. interacting
[23:47] <Rukus> is netgear garbage?

[23:54] <ngc0202> hi guys
[23:54] <Rukus> hi
[23:54] <ngc0202> I can't seem to get my rpi to boot anymore
[23:54] <Rukus> uh oh!
[23:54] <ngc0202> red light comes on and stays on but that's it
[23:54] <Rukus> start from the beginning
[23:54] <Rukus> I'm not a doctor
[23:54] * webturtle0 (~webturtle@ has joined #raspberrypi
[23:54] <ngc0202> well that's more or less the beginning
[23:55] <Rukus> oh
[23:55] <Rukus> well, is your sdcard inserted properly?
[23:55] <Rukus> is it plugged into hdmi first, then turned on?
[23:56] <Rukus> do you see th rainbow screen?>
[23:56] <Rukus> did you try a different sdcard?
[23:56] <Rukus> what was happening when you noticed this?
[23:56] * xSon1q (~xSon1q@ has joined #raspberrypi
[23:57] <ngc0202> the SD card is fully inserted
[23:57] <ngc0202> the green activity light never turns on
[23:57] <ngc0202> nothing is output to the HDMI
[23:57] <Rukus> what happenned when you tried a different sdcard?
[23:57] <ngc0202> This is the only one we've got, but we've been using it with the pi for a while
[23:57] * defsdoor (~andy@ Quit (Quit: Ex-Chat)
[23:58] <ngc0202> this just sort of happened one day
[23:58] <Rukus> my guess would be the problem solving starts at your sdcard
[23:58] <Rukus> unless you can discern its ok
[23:58] <ngc0202> it's read by my laptop just fine
[23:59] <ngc0202> I wasn't really sure what kind of things to check, but I could see everything
