[0:02] <Tim_2> any ideas of some values/hints i can play with?
[0:02] <Tim_2> or an alternative advice to check the basic function of the servo?
[0:03] <bact_> Tim_2: this channel is a ghost town, you'd probably be beter off in the forums

[2:01] <godzirra> Howdy guys. I have a quick (Hopefully) question. I see there are 17 gpio pins on the pi. Can I use all of those pins to attach a on/off style switch to?

[2:03] * yinkum (~yinkum@ has left #raspberrypi
[2:04] <pksato> godzirra: yes.
[2:06] <SpeedEvil> or you can attach switches between them, and get hundreds of switches
[2:06] * DDave (~DDave@unaffiliated/ddave) has joined #raspberrypi
[2:06] <godzirra> SpeedEvil: Its for a mame cabinet. So I don't really need hundreds. :)
[2:07] <godzirra> Oh. I only need 14.
[2:07] <godzirra> I fail at math.
[2:07] <godzirra> Oh, 15 with an insert coin one
[2:07] * debenham (~cjd@ Quit (Remote host closed the connection)
[2:07] <SpeedEvil> :-)
[2:07] <SpeedEvil> more, to detect which coin
[2:07] <godzirra> SpeedEvil: Having a switch between sounds horribly complicated and not possible to do programatically. :)
[2:08] <godzirra> Yeah, I thought about doing gauntlet which is the only game I know that matters which coin slot
[2:08] <godzirra> but I don't think I'm going to do gauntlet alone, so I opted out of that.
[2:08] <SpeedEvil> your standard keyboard has groups of switches connected between outputs
[2:09] <godzirra> Are we talking about like, shift/capslock/numlock?
[2:09] <godzirra> Or more than that?
[2:09] <SpeedEvil> about 25 or so wires
[2:09] <godzirra> I don't profess to know how a standard keyboard works.
[2:09] <SpeedEvil> for the whole keyboard
[2:09] <godzirra> I just assumed it sent serial data.
[2:09] <SpeedEvil> the internal wiring
[2:10] <pksato> godzirra: http://pcbheaven.com/wikipages/How_Key_Matrices_Works/
[2:10] <godzirra> Yeah, I guess it doesn't matter if it sends serial data or not.
[2:10] <SpeedEvil> it has a little microprocessor, with the keys wired directly to it, and scans them
[2:10] <godzirra> Reading
[2:10] <SpeedEvil> yeah, that
[2:10] <godzirra> Oh. Like an LED cube?
[2:10] <godzirra> That makes sense.

[2:12] <godzirra> This site is brilliant.
[2:14] <godzirra> Ghosting seems like it would be a nightmare for a mame console though.
[2:14] <godzirra> OH. Nevermind. I just hadn't read down far enough yet =p
[2:15] <godzirra> Thanks guys.

[2:32] <[Saint]> Where is the swap file defined in raspbian?
[2:32] <[Saint]> I would like to kill it and use my own partition layout with a dedicated swap partition

[2:50] * sleetdrop (~sleetdrop@ has joined #raspberrypi
[2:51] <[Saint]> plugwash: that's correct.
[2:51] <[Saint]> I was just wondering how I kill it.

[2:51] * Fandango (~Fandango@c-71-236-64-18.hsd1.pa.comcast.net) Quit (Quit: Fandango)
[2:51] <[Saint]> remove the tool, the sweapfile, and add an entry into fsteb manually I guess.
[2:51] <[Saint]> *swapfile
[2:51] <plugwash> sounds about right to me
[2:51] <[Saint]> *fstab
[2:51] <[Saint]> bah!
[2:52] * markbook (~markllama@pool-74-104-180-140.bstnma.fios.verizon.net) Quit (Ping timeout: 248 seconds)
[2:52] <plugwash> though personally I think swapping on SD cards is crazy anyway
[2:52] <[Saint]> for what reason?
[2:53] * offbyone (~offbyone@spf.ip6.is-is.ca) has joined #raspberrypi
[2:53] <[Saint]> I would swap in RAM if I had enough RAM free.
[2:53] * zxc (~janne@pdpc/supporter/student/kosiini) Quit (Quit: Konversation terminated!)
[2:53] <[Saint]> zram is preferable, but, not really an option when you only have 512MB total.
[2:54] <[Saint]> I suppose many people see swapping on sdcards to be slow, but, a nice sdcard fixes this.
[2:54] <[Saint]> Sandisk Ultra Pro series ftw.
[2:55] <[Saint]> 95MB/s read. ~40MB/s write
[2:55] * beet0l (~bangarang@cpe-24-193-79-42.nyc.res.rr.com) has joined #raspberrypi
[2:55] * plugwash was thinking of a combination of it being slow and being bad for the SD card
[2:55] <[Saint]> and, they're fairly cheap.
[2:55] <[Saint]> ~$90USD for the 16GB card
[2:56] <[Saint]> ~$120 for 32GB iirc
[2:56] <[Saint]> ...something like this.
[2:56] <plugwash> hmm, a search for sandisk ultra pro doesn't seem to be finding anything............
[2:56] <[Saint]> Argh.
[2:56] <[Saint]> Sorry, *Extreme Pro
[2:57] <SpeedEvil> [Saint]: you can't assume swapping is anywhere close to sustained speeds.
[2:57] <[Saint]> No, certainly not.
[2:57] <SpeedEvil> swapping, you may in some cases drop to 50k/s
[2:57] <[Saint]> plugwash: http://www.sandisk.com/products/memory-cards/microsd/
[2:57] * plugwash isn't sure he would consider over twice the price of a Pi to be "fairly cheap"
[2:58] <[Saint]> it is fairly cheap compared to comparable full-size sd options.
[2:58] <plugwash> Personally for that kind of money i'd rather just get a board that had enough ram not to need swap
[2:59] <[Saint]> I just so happened to have this card lying around anyway - from an old camera.

[3:21] <[Saint]> Why isn't the raspbian image using dynamic memory split by default?
[3:21] <[Saint]> it seems...weird.
[3:24] <godzirra> Occidentalis doesn't either, does it?
[3:24] <[Saint]> No idea.
[3:24] <[Saint]> The only one I am aware of that does, by default, is Arch.
[3:24] <godzirra> If I have a zombie process, how come I can't kill -9 it?
[3:25] <SpeedEvil> because the process is a zombie
[3:25] <SpeedEvil> not running
[3:25] <godzirra> But -9 is like a shot in the head.
[3:25] <godzirra> Boom. Headshot.
[3:25] * [Saint] nods
[3:26] <godzirra> How do I get rid of it then?
[3:26] <[Saint]> it should "just work", yes.
[3:26] <SpeedEvil> it is waiting on some event which can't complete
[3:26] <godzirra> RetroArch hung on my pi and now I can't kill it.
[3:26] <godzirra> So my main screen connected is just sitting there.
[3:26] <[Saint]> "kill -9 PID" should "just work" as far as I understand.
[3:26] <godzirra> Thats what I thought, but its not.
[3:26] <godzirra> SpeedEvil: is there any way to get rid of it then?
[3:27] <[Saint]> A hammer will work.
[3:27] <[Saint]> Or fire.
[3:28] <godzirra> That always works, but its a slightly more permanent solution than I'd care for.
[3:28] <[Saint]> ;)
[3:29] <godzirra> Great.
[3:29] <godzirra> I can kill it by killing the parent pid...
[3:29] <godzirra> Annnd the parent pid is 1. which is "init [2]"

[3:46] <godzirra> Re partition? :)
[3:46] <godzirra> I'm not sure myself.
[3:46] <[Saint]> Yeppers, parted is doing this as I type.
[3:46] <godzirra> Cool
[3:48] <[Saint]> Since I've been working on raspi-config anyway (I made it so that it respects the user that envoked it, rather than assuming the "pi" user always exists), I think I might have a go it setting up a partition menu for it as well.
[3:48] <[Saint]> So that one may set up dedicated swap, home, etc.

[3:50] <godzirra> HAving to reboot everytime the mame system decides to crash is irritating. :/
[3:50] <[Saint]> I haven't heard back from anyone about my patch set for user configuration yet, though.
[3:50] <[Saint]> ...which is slightly annoying.
[3:51] <[Saint]> Always assuming "pi" will be present is *reaaaaaaaaaly* broken to me.

[3:52] <nsgn> the networking on the pi is so slow perhaps they just figure you wont put it online by default

[3:52] <[Saint]> sigh.
[3:52] <nsgn> ssh isn't on by default..?
[3:52] <nsgn> at least it wasnt for me
[3:53] <nsgn> i had to go into raspi-config and enable it
[3:53] <[Saint]> It leads me to wonder how many zombie pis are out there dishing out spam emails. :)
[3:53] <godzirra> lol
[3:53] <nsgn> yeah, that is sad though

[3:56] <Blueness|> lol
[3:57] <Blueness|> makes sense for their to be an installer for more advanced users
[3:58] <trevorman> nsgn: its on by default in the recent versions of raspbian
[3:58] <Blueness|> how does sudo not prompt a password?
[3:58] <[Saint]> Everyone I showed it to at my local hackerspace had basically the same reaction: "I can't believe it wasn't like this to begin with".
[3:58] <godzirra> Blueness|: Why? Its not aimed at more advanced users.
[3:58] <godzirra> It'd be nice to have that, but that totally isn't the goal of the pi.
[3:59] <godzirra> So they're not putting any effort into that. Makes sense to me. :)
[3:59] <Blueness|> i'm new to linux so I just didn't know that was possible

[5:47] <nsgn> alrighty. now that i've slimmed the performance of my app for the pi considerably i'd like to take a break to learn about pi performance tweaks. obviously there is overclocking. what else may help eek extra cycles out of this little guy? i don't want to do anything that will burn it up, but i am open to shutting off unused features, etc if it will help
[5:51] <nsgn> also is it truly safe to use the official "turbo" overclocking? as in will it pull itself back if overheating or do i risk some burnt pi?
[5:51] <[Saint]> Yes, it is safe.

[5:52] <nsgn> and now i'll turn on turbo and see if it fliesssss
[5:53] <[Saint]> Be advised, though (raspi-config will tell you of this anyway) that some devices handle it better than other (manufacturing defects), and some devices tash their data with this clock speed.
[5:53] <[Saint]> So, backups, backups, backups, backups.
[5:53] <[Saint]> ...and, backups.
[5:54] <[Saint]> Oh, and backups.
[5:54] <[Saint]> :)
[5:54] <[Saint]> s/tash/trash/
[5:54] <[Saint]> TL;DR: "You may well end up with a corrupt filesystem from this clock setting"
[5:55] <[Saint]> Other things you can do:
[5:55] <[Saint]> - mount with noatime, or relatime
[5:55] <[Saint]> - install an adaptive readahead daemon
[5:56] <[Saint]> - make sure the image is aligned to the sdcard's erase block size
[5:57] <nsgn> [Saint], oh yeah i dont care if the FS is corrupt. its a base install of rasp with a python script on it that i wrote on my PC then just ssh'd to it

[5:58] <nsgn> well, all the card/filesystem IO stuff is of no benefit to me because my app runs completely in ram and does virtually no logging
[5:59] <nsgn> so do any of those assist with purely CPU bound apps? mine is bound by the CPU and (depressingly) the strikingly slow network interface
[5:59] <[Saint]> Errrr...and, what does the OS run on, my dear? :)
[5:59] <[Saint]> It is of great benefit to you.
[5:59] <nsgn> i'm aware, but i'm just telling you that when my app is running and i watch in real time there is virtually NO read write from the card, period
[5:59] <nsgn> like..the activity is none

[6:00] <[Saint]> Have a look here: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=9&t=850
[6:00] <nsgn> yeah. sorry. i should have specified i'm trying to tweak this card image to make this app fly
[6:00] <[Saint]> This has a lot of links for you to peruse.
[6:01] <nsgn> cool, thanks
[6:01] <[Saint]> Not a problem.
[6:01] <[Saint]> Avoid moving logfiles to RAM if you have a model A
[6:01] <[Saint]> ...there's simply not enough to go around.
[6:02] <nsgn> hmm..overclocking menu not only says filesystem corruption (i dont care that bad) but it says it may shorten the life of my pie :(
[6:02] <[Saint]> mounting /tmp in RAM makes a rather huge improment in speed - at the cost of quite some amount of RAM.
[6:03] <[Saint]> Well, yes, of course. You can look at it in this way - the CPU/GPU has a limited amount of cycles it can perform in its lifetime.
[6:04] <[Saint]> If you speed the clock up, you'll burn through more cycles, at a faster rate.
[6:04] * sleetdrop (~sleetdrop@ has joined #raspberrypi
[6:04] <[Saint]> In saying that, though, ...it costs ~$30 - so, "meh...".

[6:08] <nsgn> might ask that in #python? more activity in there
[6:08] <[Saint]> I'm of the opinion that it really doesn't make a considerable difference.
[6:08] <nsgn> [Saint], in life, or in performance?
[6:08] <[Saint]> But it will definitely make a measurable difference.
[6:08] <[Saint]> nsgn: in life.
[6:09] <nsgn> ok. as for performance...now rebooted. running my app...
[6:09] <[Saint]> The performance gain is apparent right away.
[6:09] <[Saint]> you should've noted a drastically shortened boot time.
[6:10] <[Saint]> My Arch install with all the tweaks I can think to throw at it gets to LXDE in ~8-10s
[6:10] <nsgn> the boot time was a bit better (though i was not looking at the screen specifically, just booting next to me)
[6:10] <nsgn> but i can say that my app has perhaps a 20 to 30% increase in performance
[6:10] <nsgn> maybe even ~40%
[6:10] <nsgn> this is nice
[6:10] * [Saint] nods
[6:11] <nsgn> do i need to worry about cooling/heat with this or is it fine just bare
[6:11] <[Saint]> No, you don't need to worry. The pi will disable boosting if it hits 80C
[6:11] <nsgn> combining this turbo mode with some further tweaking to my already drastically optimized for pi app i might actually get something useful here
[6:11] <nsgn> i wonder if it will hit that quickly since my app, even in turbo, is pegging the pi's cpu 100%
[6:12] * trentg (~trentg@pdpc/supporter/active/trentg) has left #raspberrypi
[6:12] <[Saint]> The pi will automagically disable overvolting and boosting when the CPU hits 80C
[6:12] <[Saint]> ...which is *really* hard to do, depending on the ambient temperature.
[6:13] <nsgn> oh yeah. i just meant i wonder if i'll be seeing the benefits of turbo go away quickly with my app pushing so hard
[6:13] <nsgn> but if its hard to do in a normal house (78* here indoors most of the time) i guess i'll be ok
[6:13] <nsgn> F
[6:14] <[Saint]> I doubt it. I have never seen it come close to 80C, with an ambient temp of ~30C, and prolonged use at 1GHz clock.
[6:14] <[Saint]> around 1.2GHz, however, and it will only take around ~20minutes to reach 80C with the CPU pegged.
[6:14] <nsgn> oh wow. i just realized that in turbo the app is actually coming up against my internal speed limiting on my code
[6:14] <nsgn> standby while i adjust. this is cool
[6:15] <[Saint]> I have been trying (for no real reason...heh) to reach 200% overclock - but, I fear it isn't possible unless I make myself a tiny water jacket and radiator.
[6:16] <[Saint]> ...which I am considering.
[6:16] <nsgn> haha
[6:16] <[Saint]> With a large, finned, heat-pipe sync, and two 40mm fans, I can keep 1.2GHz stable.
[6:16] <nsgn> yeah, i've heard a few people overclocking past 1ghz have killed them :(
[6:17] <[Saint]> 1.3GHz with the same setup occasionally has random panics.
[6:17] <[Saint]> ...and 1.35GHz destroyed a pi, and released the pi-geanie.

[6:19] <nsgn> nice. so with turbo applied and one more tweak (and one more typo) found in my code i now operate at 2fps
[6:19] <nsgn> this means turbo basically doubled the performance of my app, cause before turbo but after all my other optimizations it ran at 1fps
[6:19] <[Saint]> It made a rather impressive "pop.....Fizzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz" noise too :)
[6:20] <nsgn> :/
[6:20] <fr0g911> lol
[6:20] <[Saint]> WHat is the application in question, may I ask?
[6:20] <fr0g911> ive heard that sound nsgn
[6:20] <fr0g911> i put 24volts to it
[6:20] <[Saint]> yikes.
[6:21] <[Saint]> Overvolting. Like a BOSS>
[6:21] <fr0g911> yeah rofl
[6:21] <nsgn> [Saint], i've taken a 1920x1080 lcd monitor and mounted it vertical, strapped a PI to the back of it, and wrote an app that polls jpegs from 18 IP cameras in my neighborhood and displays them full screen/borderless on the PI, furiously updating them as fast as the pi's little cpu can
[6:21] <fr0g911> wow nsgn
[6:21] <fr0g911> i could use that
[6:22] <[Saint]> do you have that awesome pibow LCD mount?
[6:22] <Triffid_Hunter> nsgn: hm, wonder if the VPU can do mjpeg, that would give a massive boost
[6:22] <Triffid_Hunter> then it'd be network limited
[6:22] <nsgn> [Saint], i've learned more about python code optimization than i ever have because of this. my original working version of this program ran at 1 frame every 12 seconds. yesterday i got it down to 1 every 4 to 5. tonight i then got it to 1fps with a lot of further tweaking before turbo. and finally with turning on turbo i can run 2fps
[6:22] <[Saint]> Those pibow cases are awesome - especially with the LCD mount.
[6:22] <nsgn> no i don't have a mount. i have it hanging by wires :)

[6:23] <[Saint]> that's what I'm using presently.
[6:23] <Triffid_Hunter> heh I have a 3d printer.. if ever I want to mount it to the back of something I'll just print an adapter plate
[6:24] <nsgn> Triffid_Hunter, well, maybe. my app is written in python, though, because i'm not a programmer for a living, just a hobbiest, and choose to not write C whenever possible. python, as far as my research goes, has no real support for mjpeg. some folks have written it in. i may do so eventually, but its a crap load of work
[6:24] <nsgn> and i'm pretty sure you could not do any kind of accelerated mjpeg from within python, although maybe thats just my inexperience speaking
[6:24] <nsgn> i'm just grabbing individual jpeg stills and displaying them at an almost barable speed
[6:24] <Triffid_Hunter> nsgn: mjpeg is basically just a series of regular jpegs in a stream last time I checked.. yeah unlikely to do it from within python unless someone makes a module for the rpi's vpu
[6:24] <nsgn> 2fps is deff enough to tell what is going on for everything except the cams that show cars driving
[6:25] <[Saint]> I'd be willing to say that this would almost certainly run a lot faster in pure C than it would in python.
[6:25] <[Saint]> ...but, the conversion wouldn;t be fun.
[6:25] <Triffid_Hunter> concur
[6:25] <nsgn> Triffid_Hunter, oh yeah. i've actually done a ton of reading/learning on mjpeg. in fact i actually wrote a freaking mjpeg decoder in PHP of all things a year ago
[6:25] <nsgn> and it ran at about 20fps
[6:25] <nsgn> so i know mjpeg well, i just havent felt like the major pita it will be to write it in python
[6:26] <[Saint]> Why does you neighborhood have so many IP cams around?
[6:26] <[Saint]> Are you a technical age peeping tom? lol
[6:26] <nsgn> i'm also about 900% sure that any performance gain you would get on the http side from using mjpeg would be absolutely destroyed by the pi being unable to blit out that many images per second

[6:26] <[Saint]> wait - wha...?
[6:26] <nsgn> things are going great
[6:27] <[Saint]> mjpeg decoder in PHP?
[6:27] <nsgn> and they're only getting better
[6:27] <[Saint]> Bwahahahahaha!
[6:27] <[Saint]> ...nice.
[6:27] <nsgn> *wears shades*
[6:27] <nsgn> annyway.
[6:27] <nsgn> re PHP, it was a workaround for an odd situation
[6:27] <fr0g911> hmm wonder how i can make xbmc on a timer to start a tv news stream when i wakeup in the morning
[6:28] <[Saint]> cronjob?
[6:28] <nsgn> a client had some goofy several year old network cams that only output mpeg4 and mjpeg, but we were running zoneminder
[6:28] <fr0g911> yea but making it auto start the stream in xbmc
[6:28] <[Saint]> Ah - hummm.
[6:29] <nsgn> zoneminder had no native mpeg4 support at the time, had mjpeg but it mysteriously did not work with this camera model, but if zoneminder is great at one thing its still jpegs. ittl do them at 10 to 20fps per cam
[6:29] <nsgn> however the cams in question did not do jpeg
[6:29] <fr0g911> ive used zoneminder had alot of probs with it with foscam ip cams
[6:29] * [Saint] is slightly annoyed at pimoroni
[6:29] <nsgn> so i wote a PHP script that zoneminder would poll like it was a still jpeg
[6:30] <nsgn> every time it was polled it would open a socket to the mjpeg camera until it received one frame worth of data, close it, and quickly output it to zoneminder who was waiting on the other line
[6:30] <[Saint]> I ordered a "crystal" case, and they sent me a yellow case, affectionately named "Toxic Yellow".
[6:30] <nsgn> it worked perfectly, and is actually still running 10 cams at 10fps each at this client to this day cause they havent updated their cams or software yet
[6:30] <[Saint]> ...and by god, they're right about the toxic part.
[6:30] <fr0g911> only thing i can think of is cronjob start xbmc and have it auto load playlist
[6:30] <nsgn> [Saint], so yeah. i wrote a friggin mjpeg decoder in php
[6:31] <nsgn> for a production env, noless
[6:31] <[Saint]> that is impressive.
[6:31] <[Saint]> Both in application, and the fact that you're still (I assume, at least partly) sane afterward.
[6:31] <nsgn> it was a really short piece of code..it just took hours of sorting through raw dumps of the dlink camera mjpeg stream to find out it was outputting a NON STANDARD mjpeg stream
[6:31] <nsgn> which is why zoneminder could not read it on its own
[6:32] <nsgn> once i realized what it was doing i was able to write the custom script for it
[6:32] <nsgn> next time the server crashes i'm putting in blue iris in place of zoneminder and calling it a day
[6:33] <nsgn> after years and years of loyally using and contributing to the zoneminder project i finally gave up. for $50 ($25 if you buy in bulk) blue iris is a vastly superior piece of software. regularly updated/improved to boot
[6:33] <nsgn> and has nearly all the same HTTP interfaces as zoneminder, so i can still write cool stuff for it like what i did right now on my pi
[6:33] <Triffid_Hunter> nsgn: hah trust dlink to break things
[6:34] <[Saint]> I ordered this ( http://shop.pimoroni.com/collections/pibow/products/pibow-crystal ) "crystal" case X2, and the VESA backplate X2, and recieved this ( http://shop.pimoroni.com/collections/pibow/products/pibow-toxic ) "toxic yellow" case X2 instead.
[6:34] <nsgn> Triffid_Hunter, yeah. didnt recommend those cams. current budget cam i recommend is ubiquiti aircam. not much more open than the dlinks, though it does run linux and you can SSH into it....it is a darn good cam for the price and works flawlessly with blue iris
[6:34] <nsgn> and now with my pi :)
[6:34] <[Saint]> So, if anyone wants a terribly ugly bright yellow case when the replacements arrive - they can have it for shipping cost.
[6:34] <fr0g911> goodnight
[6:35] <[Saint]> pibow is being good enough to replace the order with what I wanted, and let me keep the nasty yellow ones.
[6:36] <[Saint]> Someone at my hackerspace actually *wants* one of them (uuuuuugggggh), so - I'll have one left to get rid of.

[6:36] <[Saint]> I assume shipping will be a few bucks. I'll post in here when I recieve the replacements.
[6:37] <[Saint]> For the moment, I need them, nast toxic yellow or no.
[6:37] <[Saint]> I /could/ paint them, I guess, but then the whole transparent awesome effect is lost - which is the entire reason I wanted to get these cases (as well as build quality) from the beginning.
[6:38] <[Saint]> they are one of the very few cases I have seen that are crush proof: http://cdn.shopify.com/s/files/1/0174/1800/products/pibow-crystal_1024x1024.jpg?2622
[6:40] <[Saint]> I needed to make some modification to it, though, so that the heat-pipe and sync would fit outside the case, because it definitely wouldn't fit inside it.

[6:57] <nsgn> [Saint], he was just being silly. i didnt take it as that wild. its all good
[6:57] <nsgn> i think your pi overclocking is cool ;)
[6:58] <[Saint]> Its actually quite hot ;)
[6:59] <nsgn> heh
[6:59] <nsgn> do some liquid nitrogen cooling or something
[7:00] <Ben64> i just don't get the point. slightly better performance at the cost of stability and possible hardware damage
[7:00] <[Saint]> Yeah, the thing is - it isn't "slightly" better performance.
[7:01] <[Saint]> nsgn jumped up 300MHz, and doubled the performance of his application.
[7:01] <[Saint]> nsgn: I've been looking around trying to find a small enough plate for liquid cooling, but I think I'll have to bust out my CAD skills and get one machines.
[7:01] <nsgn> Ben64, it's interesting with the pi. there are two categories of overclocking; the official, in warranty stuff and then the beyond 1ghz stuff
[7:02] <nsgn> ben64 but i can actually tell you that the performance benefits on the pi are pretty huge. i went from pi default to the max allowed within warranty of 1ghz and it made my app run 2x faster
[7:02] <[Saint]> Indeed. I've been playing with "the scary stuff". Because its a: enjoyable for me to do so, and b: a challenge.
[7:03] <nsgn> as far as things you can overclock reasonably the pi is probably the cheapeast possible one
[7:03] <nsgn> can you think of a system you can have fun overclocking that costs less?
[7:03] <Ben64> i dunno, just seems like at that point a different board would be better

[7:05] <nsgn> *not
[7:05] <Ben64> i'm trying to decide if having a pi in my car would be worth it
[7:05] <nsgn> Ben64, that'd be cool. what kind of stuff you wanna run on it?
[7:05] <nsgn> multimedia, telemetry, something else?
[7:05] <Ben64> music mostly
[7:05] <[Saint]> Yeah - I use one to give my server a kick in the balls when it needs it.
[7:05] <nsgn> ah
[7:06] <nsgn> if my server ever went down i'd put one for that too
[7:06] <[Saint]> ssh in and give the reset and/or power switch a tweak via gpio.
[7:06] <nsgn> it has an uptime of about 600 days right now
[7:06] <Ben64> not sure if it would drain the battery being on 24/7
[7:06] <nsgn> Ben64, dont have it on 24/7
[7:06] <nsgn> most vehicles have a few circuits that automatically cut on/off with the car
[7:06] <nsgn> wire into that
[7:06] <[Saint]> Yeah - why would you do that - wire it up to accessory.
[7:06] <nsgn> i did that in my scion for some stuff
[7:06] <Ben64> so i wouldn't have to wait for it to boot :)
[7:06] <nsgn> unless you wanted to have constant communication with it by wifi
[7:07] <[Saint]> I'm sure you could trivially make a little bank of caps to give it enough juice to power down safely.
[7:07] <[Saint]> or, just make the card RO.
[7:07] <nsgn> in which case, honestly, the pi uses so little juice that if you dont let your car sit for any more than a day or so at a time between uses you could probably run the pi constantly
[7:07] * [Saint] nods
[7:07] <nsgn> then just put a switch under the dash to cut it from constant power when parking for longer
[7:07] <Triffid_Hunter> Ben64: last time someone asked, I vaguely recall working out that the car would have to be started every 2 days worst case or you risk reducing the battery life
[7:07] <[Saint]> If you use the car every few days, you probably could safely have it connected 24/7
[7:08] <[Saint]> it is quite efficient on power.
[7:08] <nsgn> i think it'd be awesome to have a little computer in the car that had wifi on it and, when you pull in the garage, it connects and communicates with the house
[7:08] <nsgn> dang. that sounds so cool i may do that
[7:08] <[Saint]> I used to have a mini2440 in my Valliant.
[7:08] <[Saint]> But, someone stole it.
[7:08] <Ben64> i was thinking i should get a router in there too, so i could ssh in from the road
[7:08] <[Saint]> ...oh, sorry, I lie. It was in the Allegro, not the Valliant.
[7:08] <Triffid_Hunter> Ben64: you want a gsm dongle for that
[7:09] <Ben64> i'm not trying to connect it to the internet
[7:09] <Ben64> just a local network
[7:09] <[Saint]> Someone managed to get into my car, remove the amp, the subs, the front 6"s, the rear 6X9"s and the mini2440 and touchscreen - all without setting off the alarm.
[7:09] <[Saint]> I really had to give them some credit for that.
[7:10] <nsgn> Ben64, you can probably do that with a wifi adapter on the PI and use less power than a router
[7:10] <nsgn> adhoc network
[7:10] <Triffid_Hunter> [Saint]: probably exploited a known weakness of the alarm.. acquaintances in those circles tell me that many car alarms can be disabled by breaking one of the rear tail lights
[7:10] <[Saint]> Triffid_Hunter: I think they were just *really* careful...but, I'm not sure.
[7:11] <[Saint]> I set the alarm off myself inthe morning when I "WTF!?!"ed.
[7:11] <nsgn> but i've gotta crash now. be back tomorrow. night [Saint], ben64
[7:11] <[Saint]> o/
[7:11] <Ben64> i could easily make the pi power on when the car starts, and automatically play a hard drive full of songs
[7:11] <Ben64> but i would like to be able to control it too...
[7:12] <[Saint]> This is what I used to play with in the days before such things as the raspi and odroid u/x 2 existed: http://www.friendlyarm.net/products/mini2440
[7:12] <nsgn> honestly a pi set in turbo using raspi-config boots raspbian so fast you really shouldnt have to worry about boot time
[7:12] <[Saint]> Ben64: chalkelec makes some nice touchscreens for the pi.
[7:12] <[Saint]> in 7 and 10" variants.
[7:12] <Ben64> the problem is it has to be in the trunk
[7:12] <[Saint]> Ahhhh...Hum.

[11:20] <gordonDrogon> troulouliou_dev, to control an OUTPUT then you don't need a pull-up as such, but you are writing to an LED, then that LED does need a resistor.
[11:21] <troulouliou_dev> gordonDrogon, i was just reading a book about raspberry where the writer direcly plug a led between 3.3 and ground
[11:22] <troulouliou_dev> just saw to internaly there already was a pull up per gpio pin

[11:22] <DreamyDays> ,
[11:23] <gordonDrogon> troulouliou_dev, do that and the LED will blow up.
[11:23] <gordonDrogon> you always should use a resistor with an LED.
[11:23] <gordonDrogon> there are some LEDs that have it built in though, but they're not generally used.
[11:24] <gordonDrogon> troulouliou_dev, start here for some examples: https://projects.drogon.net/raspberry-pi/gpio-examples/tux-crossing/gpio-examples-1-a-single-led/

[11:30] <gordonDrogon> Grievre, OpenGL ES AIUI, but I'm no expert in that area at all...
[11:30] <troulouliou_dev> gordonDrogon, maybe the author asume that 3.3 won't blow a led

[11:33] <bha> Hello everyone
[11:33] <gordonDrogon> LEd is easy. you read the data sheet for the LED and it wil ltell you the voltage drop at a particular currrent. You then use Ohms law to work out the resistor needed.
[11:33] <bha> is anyone from dutch?
[11:34] <gordonDrogon> or you just make it up and use a 220 or 330?? resistor for an average LED at 3.3v

[11:35] <bha> I would like to purchase raspberry pi, my parents flys to amsterdam tonight, is there any shop there that sells it? I'd like to know one
[11:35] <gordonDrogon> bha, no idea about being able to get one over the counter there. start googling :)
[11:35] <gordonDrogon> or post in the raspberrypi.org forum, etc.
[11:35] <troulouliou_dev> gordonDrogon, sorry to overflow but i m a noob :) i have a 4511 that i want to control with pi to light a 7 segment led; should i put a resistor between the gpio and bcd pin of the 4511 ?
[11:36] <bha> yeah i've googled but it's dutch langugue
[11:36] <bha> ;x
[11:36] <gordonDrogon> troulouliou_dev, just a tick, I'll check the chip.
[11:36] <troulouliou_dev> gordonDrogon, it isa bcd to 7 seg led decoder
[11:38] <gordonDrogon> troulouliou_dev, you'll need 7 resistors.
[11:38] <gordonDrogon> for the LED segments, but can connect from the Pi's GPIO (x4) directly into the chip.
[11:39] <troulouliou_dev> gordonDrogon, how did you undestood that ? based on the datasheet ?
[11:39] <gordonDrogon> yes.
[11:39] <bha> I can't find any shop, all are online shops
[11:39] <Grievre> I doubt you want to power any led of non-trivial brightness directly off of the pi's GPIO pins
[11:39] <gordonDrogon> Grievre, 15mA is a very bight LED.
[11:39] <gordonDrogon> http://unicorn.drogon.net/pi17leds.jpg
[11:40] <troulouliou_dev> gordonDrogon, and my 7 led are common anode ;so i have to control with 7 transistor ; should i put a resistor between the pin of the 4511 and the base of the transistor ?
[11:40] <gordonDrogon> troulouliou_dev, probably. but it's just to limit the base current.
[11:40] <bha> is anyone from dutch can tell me where their shop at? http://nl.rs-online.com/web/generalDisplay.html?id=raspberrypi
[11:41] <gordonDrogon> troulouliou_dev, you can drive it directly off the Pi though - 7 GPIOs directly into 7 resistors into the 7-segment display.

[11:42] <troulouliou_dev> ha great
[11:42] <gordonDrogon> only 1 resistor per digit there too - because I'm only lighting 1 segment at a time.
[11:44] <troulouliou_dev> but you are using common cathode
[11:44] <troulouliou_dev> so you don't need transistor
[11:44] <troulouliou_dev> here i only have common anode and in my country, finding electronic component is a hard task ;)
[11:44] <gordonDrogon> it wouldn't matter if it were the other way round. just change 1's for 0's in the code (and vice vesa)

[11:46] <gordonDrogon> yes.

[11:46] <gordonDrogon> the pi's outputs will sink and source current.

[11:49] <gordonDrogon> hnsr, experiment and blog about it - I'm sure others will benefit from knowing if it works or not!
[11:49] <hnsr> hm I guess I might
[11:50] <hnsr> for some reason I can't find anything cheaper than ???15 :s
[11:50] <neilr> mmm, looking at that seven segment LED stuff has got me pondering on controlling nixie tubes from a pi

[14:23] <mgottschlag> I plan to make "a proper PCB" for it, although I have no experience in making PCBs :|

[16:42] <TheSeven> stupid pi.
[16:42] <TheSeven> updated the kernel and a few other packages, now it won't boot.
[16:43] <bact> TheSeven: congrats, welcome to the club
[16:44] <TheSeven> it starts to boot, successfully mounts the rootfs, starts up various drivers, and then just locks up
[16:44] <TheSeven> not sure if it's actually locked up or just doesn't spawn any console for some reason
[16:44] <bact> have you tried threatening it?
[16:44] <TheSeven> might be worth a try...

[16:52] <steve__> hey :)
[16:53] <steve__> i have some questions about rpi, can i ask them to you?
[16:53] <aganders3> just ask, don't ask to ask
[16:53] <ShiftPlusOne> you can ask everyone here and if someone can answer, they will.
[16:53] <steve__> ok thanks :)
[16:54] <steve__> i am an IT student and i want to build a rpi-based quadcopter
[16:54] <steve__> i've readed about real time OS
[16:54] * omgmog (~omgmog@ Quit (Quit: Computer has gone to sleep.)
[16:54] <steve__> and i learned about some patches

[16:56] * TheSeven recommends some ARM-based flight controller board
[16:57] <steve__> i mean, with pi i have more calculation power, but is not real time
[16:57] <TheSeven> there's a nice stm32-based one, which already has a bunch of on-board sensors
[16:57] <steve__> so the I/O is not equivalen to an arduino or other micro
[16:57] <buzzsaw> there are people doing amazing things with arduino and quadcopters...
[16:57] <TheSeven> realtime is primarily a matter of software, but certain platforms just make it easier by providing some readily-made infrastructure
[16:57] <steve__> yeah i readed about this
[16:58] <ShiftPlusOne> TheSeven, are those sensors actually any good for this application? The board came with a demo where the leds light up based on the accelerometer and they were all over the place.
[16:58] <buzzsaw> g o r d o n D r o g o n, was talking about the quadcopter and pi a few days ago

[17:04] <TheSeven> this is the one that I was talking about
[17:06] <ShiftPlusOne> TheSeven, ah, so that one is actually made specifically for the application. I thought you were talking about the F4 DIscovery board or similar
[17:06] <TheSeven> no, the discovery board isn't quite suited for that purpose

[17:29] <buzzsaw> perhaps you should use a DDS :-)
[17:29] <buzzsaw> that way you could get other ranges too

[17:30] <TheSeven> seems easiest to go through whatever audio APIs are there
[17:30] <dreamreal> I was thinking of using the pi as a simple synthesizer
[17:31] <TheSeven> so what you're looking for is basically how to play back runtime-generated audio on linux?
[17:31] <dreamreal> yeah, I'm googling for it already
[17:32] <dreamreal> wasn't really thinking on linux as being the transport level
[17:34] <TheSeven> actually it isn't really linux but rather a sound system, probably alsa in this case
[17:34] <dreamreal> sure, but the concept is workable... and simpler. I was thinking about the pi, specifically, when apparently I should have been thinking alsa or whatever

[21:25] <ripzay> i did that at collete
