Aug 18 07:04:34 python, for example Aug 18 07:04:43 Okk Thanks..... Aug 18 07:04:54 i think basic gpio stuff can be done by file accesses in /sys ? Aug 18 07:05:04 if you already know some arduino programming, look at bonescript Aug 18 07:05:15 and also wnat to know How its performance on controlling CNC? Aug 18 07:06:59 no idea. if you know what performance you need, try it and see if the board is sufficient Aug 18 07:07:06 Ok Aug 18 07:07:31 By the ways thanks for guidance Aug 18 07:07:39 thank you very much Aug 18 09:53:28 * mranostay mru shakes in Aug 18 09:57:55 mrpackethead: go to bed, you're drunk Aug 18 09:57:58 er.. Aug 18 09:58:03 mranostay: go to bed, you're drunk Aug 18 09:58:07 * KotH is not fully awake yet Aug 18 09:58:11 i'm not drunk Aug 18 09:58:15 but i'm rather shaken still Aug 18 09:58:23 poor kwiw Aug 18 09:58:25 er.. Aug 18 09:58:26 poor kiwi Aug 18 09:58:34 * KotH goes back to bed Aug 18 09:58:34 i'm drunk but not sleeping Aug 18 09:58:44 lame KotH Aug 18 09:59:03 lame? Aug 18 09:59:11 unlike you i have to leave the house to get drunk! Aug 18 10:00:06 boo i was over at the bar next door Aug 18 10:03:03 wow! how did you manage that long trip back home? Aug 18 10:03:19 KotH: bite me mofo Aug 18 10:03:40 no thanks, you are not kosher Aug 18 10:04:08 alcohol kills all Aug 18 10:04:59 * mranostay wonders how fired his Kernel Summit hobbyist submission can get him Aug 18 10:05:14 " An unidentified Taiwanese woman died of alcohol intoxication after immersion for twelve hours in a bathtub filled with 40% ethanol. Her blood alcohol content was 1.35%. It was believed that she had immersed herself as a response to the SARS epidemic." Aug 18 10:05:30 nice.... Aug 18 10:05:30 mranostay: what did you submit? Aug 18 10:06:04 beaglebone "vendor" tree to mainline Aug 18 10:06:15 why should that get you fired? Aug 18 10:06:32 america companies :) Aug 18 10:06:41 hmm... does intel have one of these "thou shall not have any other processeors beside me!" comandments? Aug 18 10:07:00 KotH: at will employmeny here Aug 18 10:07:17 they don't like the colour of my shirt they can fire me Aug 18 10:07:37 * KotH knows why he stays in europe Aug 18 10:09:40 I doubt they'll fire someone valuable :p Aug 18 10:10:16 * KotH is not really valuable Aug 18 10:10:25 * KotH is just a know-it-all asshole Aug 18 10:11:36 ynezz: big companies it doesn't matter Aug 18 10:12:01 there are people that babysit bash scripts that have more job security Aug 18 10:13:20 that sounds like you are in the wrong group Aug 18 10:15:05 * mranostay should have been born in france Aug 18 10:15:57 <_SY_> hello Aug 18 10:16:01 huh? you like wine? Aug 18 10:16:05 babysitting bash scripts is highly technical talent Aug 18 10:16:07 i thought you are a beer person? Aug 18 10:16:07 i hate this culture of you don't work over 40 hours you are a "slacker" Aug 18 10:16:39 chances are the alternative would be someone copypasting lines in excel Aug 18 10:16:47 * KotH is not even working 40h/week Aug 18 10:16:47 KotH: 1664 sucks yes Aug 18 10:17:12 we all die working long hours is silly Aug 18 10:17:25 <_SY_> In my experience those that work the hardest are paid the least. Aug 18 10:17:42 * mranostay thinks americans culture of believing in afterlife is blame Aug 18 10:17:43 it's not bad unless you have a word for diying-from-exhaustion-at-work... like the japanese do Aug 18 10:17:46 _SY_: +1 Aug 18 10:18:05 <_SY_> live bee's the workers work 24/7 from the time they are born till the time they die....poor workers Aug 18 10:18:22 <_SY_> *like Aug 18 10:18:48 _SY_: actually, it's different: those who get the most money are those who "produce" something intangible. the more difficult it is to measure what you do, the more you earn Aug 18 10:19:34 <_SY_> Not strictly true...I work for a couple of people that actually don't do much at all...just take big salaries...hence I won't be working for them much longer. Aug 18 10:20:08 <_SY_> Sorry I see what you mean... Aug 18 10:20:34 <_SY_> But always seems that those that do the most and hold the company together are actually rewarded the least. Aug 18 10:20:45 juup Aug 18 10:20:59 they care too much about they work to hagle for more salary Aug 18 10:21:12 _SY_: problem with big companies that people are around that do nothing Aug 18 10:21:32 but can play the system enough to get paid Aug 18 10:22:01 <_SY_> In big companies its a different problem, people can hide away unnoticed for years doing very little....where as in smaller companies its easier to spot the wasters Aug 18 10:22:46 spot the wasters? any good team leader can do that. what's different is that big companies can afford those, small companies cannot Aug 18 10:22:57 <_SY_> Usually what happens in a big company is that people are promoted to there level of incompetance, which normally means that those that are useless end up running the company. Aug 18 10:23:43 that too Aug 18 10:23:46 dilbert applies Aug 18 10:24:05 heh Aug 18 10:24:33 <_SY_> just had a great week away on holiday, the only thing wrong with holidays is the feeling you get when its all over and you have to go back to the office....time to find a new job :) Aug 18 10:24:49 heh Aug 18 10:26:26 _SY_: hehe..same here Aug 18 10:26:41 _SY_: the moment i stop caring about what i'm doing is the moment i need to look for a new job.. quickly Aug 18 10:27:45 <_SY_> I'm gearing up to go back to contracting...think thats the only way I'm going to be happy....that way I can do a whole bunch of stuff legally and still earn a lot more. Aug 18 10:28:55 * mranostay would love to do contracting but the lulls are scary Aug 18 10:29:12 lulls? Aug 18 10:29:19 no work Aug 18 10:29:27 life is scary Aug 18 10:29:41 yes it is Aug 18 10:29:47 <_SY_> Security in a job is an illusion, people think they are safer being employed, but the reality is that you are just as likely to be laid off due to rationalisation as an employee. Aug 18 10:30:14 can i be unborn? :) Aug 18 10:30:15 <_SY_> As a contractor you can earn double and pay less tax legally, so you have a buffer. Aug 18 10:30:28 mranostay: man! you're young, you dont have family, you are not bound to one place. you can always go back to what you are doing now. what are you scared of? Aug 18 10:30:51 _SY_: you have to have a buffer Aug 18 10:31:39 in america you have to live paycheque to paycheque :P Aug 18 10:31:47 our company does contract work... in 2009 we were nearly bankcrupt because we had a total of 3 small projects (usually it's in the order of 10 midsized per year) Aug 18 10:31:51 <_SY_> I am 43, four kids, 2 of which are in Uni now...no.3 just left school, about to start college, no.4 still in school....I pay a lot more tax as an employee than I would as a contractor, I know I could earn upwards of 80K as a contractor and pay half the tax. Aug 18 10:32:12 if $boss wouldnt had prepared reserves for this, i would have lost my job Aug 18 10:32:26 mranostay: why? Aug 18 10:32:36 mranostay: can't you save money? Aug 18 10:32:36 KotH: we are stupid :P Aug 18 10:32:50 mranostay: stupidity is something personal Aug 18 10:32:54 <-- has a year of barebones savings Aug 18 10:32:59 mranostay: you dont have to live like everyone lese Aug 18 10:33:06 i don't :) Aug 18 10:33:23 <-- grew up poor as shit Aug 18 10:33:37 _SY_: 80k in what currency? Aug 18 10:33:44 _SY_: gbp? Aug 18 10:33:48 <_SY_> GBP Aug 18 10:33:54 o_0 Aug 18 10:34:06 80k? that isn't a lot Aug 18 10:34:14 it isnt Aug 18 10:34:22 unless you are in Iowa Aug 18 10:34:28 or Ohio Aug 18 10:34:40 that's about the average salary of an 30 something EE employee in .ch Aug 18 10:34:49 <_SY_> Its enough....the going rate for contractors in the UK hasn't really changed in 20 years. Aug 18 10:34:56 ouch Aug 18 10:35:01 :-( Aug 18 10:35:27 <_SY_> In comparision, electricians, plumbers etc now earn more than qualified engineers. Aug 18 10:35:38 ouch Aug 18 10:35:53 then you, as engineers in general, did something wrong Aug 18 10:36:33 <_SY_> The thing is that as a contractor I can earn �80,000 and pay 20% tax....but as an employee if I was paid �80,000 I would pay over 40% in tax. Aug 18 10:36:45 salary in general is a function of what people demand to earn. if everyone just says they want to earn a little bit more than they get offered, salaries will rise over the years Aug 18 10:36:54 40%??? Aug 18 10:37:07 you are not living in a scandinavian country! Aug 18 10:37:24 <_SY_> The higher rate for tax in the UK is currenlty �43,000 Aug 18 10:37:38 i pay around 12% or so Aug 18 10:37:48 and that's because i dont have kids and live alone Aug 18 10:37:48 <_SY_> lucky you :) Aug 18 10:38:00 <_SY_> I pay 40% on quite a lot of my income. Aug 18 10:38:12 heh in the US you pay more tax as a contracor Aug 18 10:38:14 it would be probably 20% if i'd earn 300k chf a year.... Aug 18 10:38:23 and have to float your insurance Aug 18 10:38:27 Hello all! Aug 18 10:38:33 greetings Splat725 Aug 18 10:38:44 <_SY_> In the US taxes are very low, just look at fuel....we get screwedin the UK for tax on fuel. Aug 18 10:38:58 Splat725: what do you work, how much do you earn and what percentage do you "spend" on taxes? Aug 18 10:39:02 well frankly fuel tax in the US needs to be much higher Aug 18 10:39:28 I am a student :| Aug 18 10:39:34 High school Aug 18 10:39:35 public transit only exists in like a dozen cities Aug 18 10:39:47 Splat725: oh.. enjoy your life while you can! :) Aug 18 10:39:56 Trust me I am! Aug 18 10:40:01 <_SY_> I drive a 1.4 litre Mazda 2, it costs be 40 GBP to fill it up, much of that is tax...when I was in the US, I drove a 5 litre dodge 4x4, that cost me 5 dollars to fill up. Aug 18 10:40:03 Splat725: no, you are not! Aug 18 10:40:07 Splat725: finish college! Aug 18 10:40:12 Splat725: it's sunday evening and you are at home at your computer Aug 18 10:40:19 Splat725: go out man! meet people! Aug 18 10:40:24 Splat725: or read a good book ;) Aug 18 10:40:29 Splat725: go get laid! Aug 18 10:40:40 :| Aug 18 10:40:41 Splat725: dont listen to mranostay, he is a drunk usian Aug 18 10:40:47 whoa is it 4a... Aug 18 10:40:51 I came here to talk about the beaglebone :P Aug 18 10:41:02 we dont talk about the beaglebone here Aug 18 10:41:04 <_SY_> whats your question? Aug 18 10:41:23 http://26-26-54.hardwarebug.org/146 Aug 18 10:41:44 <_SY_> :P Aug 18 10:41:51 No question, I was thinking of using one as the core of a robot I planed to build Aug 18 10:41:58 mranostay: you know what's funny: when i was in highschool, most people didnt get laid until after graduating from hs Aug 18 10:42:11 KotH: yes same here... Aug 18 10:42:28 Splat725: core? Aug 18 10:42:44 PRUs or the ARM core? Aug 18 10:42:57 mranostay: core as the center of the robot Aug 18 10:43:03 Wrong term possibly? The heart, the life line, the conrtoller? Aug 18 10:43:18 What KotH said ;) Aug 18 10:43:20 Splat725: nah.. right term. mranostay is drunk, really Aug 18 10:43:32 KotH: semi-sober Aug 18 10:43:37 just late Aug 18 10:43:41 Splat725: and "core" has different meanings and is more often used as "processor core" Aug 18 10:44:02 Highschool in australia goes from years 7 to 12 and ages 13 to 18. I am 18. For anyone interested Aug 18 10:44:02 <_SY_> I've done some pretty cool stuff with my two BBB....got them clustered together, running high availability mysql multi-master, with my own floating IP manager, all works well...have also written a modbus slave driver for ethernet that puts the I/O into the SQL database. Aug 18 10:44:15 mranostay: http://26-26-54.hardwarebug.org/171 ;) Aug 18 10:44:22 I am aware :P That's why I figured I used the wrong term KotH Aug 18 10:44:53 KotH: i need to send that page to my mom.. she wouldn't be proud :P Aug 18 10:45:33 mranostay: :-) Aug 18 10:45:40 mranostay: say hi to her from us :) Aug 18 10:46:23 Splat725: so what's your question about the bbb? Aug 18 10:46:23 I am using a Raspberry Pi at the moment Aug 18 10:46:29 ugh! Aug 18 10:46:38 well.. you are young and didnt know better ;-) Aug 18 10:46:55 * mranostay zzzzzzzzzzzzzzzzz Aug 18 10:47:09 mranostay: sleep well.. and dont let panto bite you in your sleep Aug 18 10:47:10 My main question was where to source a BBB in australia Aug 18 10:47:29 Splat725: whats wrong with digikey, mouser, farnell? Aug 18 10:48:46 The fact I had never heard of any of them! Aug 18 10:49:07 Splat725: http://beagleboard.org/ Aug 18 10:49:17 Splat725: there is a "purchage" drop down menu Aug 18 10:49:24 Splat725: use that to find one of the sellers :) Aug 18 10:49:46 i dont know which one is the cheapest to buy from .au Aug 18 10:50:08 oh.. and you want to bookmark mouser and digikey Aug 18 10:50:15 What is the difference between the Black Beaglebone and the White one (I know it isn't referred to as the white one but the name has escaped me, I think it was a dev one) Aug 18 10:50:17 best places to buy all kind of electronic components Aug 18 10:50:29 mostly different processor Aug 18 10:50:52 for your thing bbb is better than the bbw because it's cheaper :) Aug 18 10:51:14 Of course, I just saw the two and the price difference and was curios! Aug 18 10:51:17 and yes, it's nowadays refered to as beagle bone white Aug 18 10:51:46 the price difference comes mostly from different expectations at the design phase Aug 18 10:52:01 the bbb was optimized for low price and is produced in larger batches Aug 18 10:52:22 while the bbw tried to be complete with everything and was/is produced in "low" volumes Aug 18 10:52:23 So the main difference is the white is more powerful? Aug 18 10:52:46 i dont think the bbw is more powerfull than the bbb Aug 18 10:52:59 but i dont know the specs of the two boards from the top of my head Aug 18 10:53:09 How many GPIO pins are programmable on the BBB? Aug 18 10:53:19 that's written in the manual Aug 18 10:53:50 _SY_: do you have time to take over? Aug 18 10:53:55 _SY_: i should get up and get some work done Aug 18 10:54:48 <_SY_> sorry, what do you mean? Aug 18 10:55:14 take over the channel duty while i'm afk :) Aug 18 10:55:33 Hello SY :) Aug 18 10:55:37 <_SY_> I don't think I know enough about IRC to do the job Aug 18 10:55:42 <_SY_> hello Splat725 Aug 18 10:55:54 What's up? How are you? Aug 18 10:56:05 <_SY_> I'm ok, messing with Node atm... Aug 18 10:56:57 I will try not to bother you too much Aug 18 10:57:14 <_SY_> np...ask me whatever you like :) Aug 18 10:58:16 I assume you use the BBB regularly? Aug 18 10:58:28 <_SY_> Yes...for my own projects. Aug 18 10:59:14 Anything Mechatronic? Aug 18 10:59:40 <_SY_> I haven't with BBB, I've designed an written a ROV control system years ago... Aug 18 10:59:42 <_SY_> on PC. Aug 18 11:00:44 I have been playing around with some motor and light controls with a Raspberry Pi Aug 18 11:01:18 <_SY_> using what language? Aug 18 11:01:24 Python Aug 18 11:02:22 <_SY_> ok, I'm no expert in python...for motor control I would have thought C/C++ would be better suited. Aug 18 11:03:39 Python doesn't seem to work all that bad for this, Basically all I was doing was turning on some motors with a wiimote Aug 18 11:03:49 <_SY_> For motor control you will probably want some kind of closed loop control such as PID, which requires good timing. Aug 18 11:04:40 If actually controlling a brushless motor - it's likely that the PRUs will be nearly ideal Aug 18 11:04:49 Brushed motor Aug 18 11:05:03 For brushed - pwm units will work fine Aug 18 11:06:07 Thank you Aug 18 11:06:52 Splat725: you dont need a control loop for a motor if you use it just for motion. just set the ratio of the pwm and you get a speed that is nearly constant over a flat surface Aug 18 11:07:12 Splat725: if you need positioning, buy a servo, like the ones use in model planes Aug 18 11:07:43 I saw a video of someone who made a rover on youtube (http://www.youtube.com/watch?v=neiOY1Uy6g8) and thoight it would be a good idea to make my own! Aug 18 11:07:50 Splat725: there you can set the position of the servo using pwm and dont have to care about writing a tight control loop (which is not easy unles you know what you are doing) Aug 18 11:07:56 I have a number of them handy KotH so that would be perfect Aug 18 11:08:32 <_SY_> The control loop comes in if you need to change direction, for example in an ROV the motors control thrust, heading and altitude. Aug 18 11:08:39 Splat725: you can see in the video that the "head" is moved by such servos Aug 18 11:09:19 I am aware, my father and I have been aircraft modelling for about 3 years now1 Aug 18 11:10:17 <_SY_> I g2g...should be back later, have fun Aug 18 11:18:46 The BBB uses an SD card for the OS? Aug 18 11:19:17 It can Aug 18 11:19:24 It can also boot from internal flash Aug 18 11:19:43 What's the largest SD card that is compatible with the BBB Aug 18 11:20:42 Splat725: 10x15mm Aug 18 11:22:21 mru: be nice to Splat725, he is a high school student Aug 18 11:22:24 :) Aug 18 11:22:59 I answered the question Aug 18 11:23:04 Splat725: size is less a matter than type Aug 18 11:23:16 now had he asked for the highest capacity supported... Aug 18 11:23:26 Splat725: often some brands exhibit some quirks that make them impossible to use in such an application Aug 18 11:23:54 Splat725: just get a cheap one from the local store and try it. if it doesnt work, get another one Aug 18 11:23:56 what application? Aug 18 11:24:32 I read a lot of people were purchasing 128GB SD cards and they were finding them incompatable with their RPis Aug 18 11:25:10 those would be sdxc Aug 18 11:25:45 Splat725: incompatible? as in "does not get full size" or "does not work at all" Aug 18 11:25:48 ? Aug 18 11:26:22 With an i yes, sorry Aug 18 11:26:29 aren't sdxc cards supposed to simply be clipped to 32G in an sdhc-only device? Aug 18 11:26:37 And I can't remember exactly Aug 18 11:26:50 mru: shouldnt sdhc -> sdxc be a software thing? Aug 18 11:26:55 Let me see if I can find the thread Aug 18 11:27:11 like large hard drives on an ata controller without lba48 Aug 18 11:27:24 oh... Aug 18 11:27:27 yes.. Aug 18 11:27:30 * KotH is stupid Aug 18 11:28:00 I don't remember if the host controller needs to support sdxc Aug 18 11:28:06 there's definitely software involved Aug 18 11:28:38 as usual, the difference is the addressable unit size and the number of address bits Aug 18 11:28:59 Must have been reading about something else, I can find threads saying they will work, none saying otherwise, so no problem Aug 18 11:33:21 then there's a lot of confusion on the internet regarding exfat Aug 18 11:33:44 there is absolutely no requirement to use exfat on sdxc cards Aug 18 11:34:11 uhmm... doesnt the standard demand that any compliend sdxc device can read exfat? Aug 18 11:34:21 or am i imagining things? Aug 18 11:34:29 exfat is most definitely a software thing Aug 18 11:34:38 * KotH hasnt read the standard in detail yet Aug 18 11:34:44 there's nothing in the card itself that requires it Aug 18 11:34:48 sure Aug 18 11:35:01 the spec may well mandate it for micrsoft royalty reasons Aug 18 11:35:34 but if you don't care about displaying the logo, you can do whatever you want Aug 18 11:39:02 KotH: what quirks were you talking about earlier? Aug 18 11:40:24 mru: sdcard type <-> uC compatibility Aug 18 11:40:41 type meaning what? Aug 18 11:40:43 brand? Aug 18 11:40:50 mru: i had bad experiences with using certain sdcards on some uC/uP�'s Aug 18 11:40:57 yes, brand, specific type Aug 18 11:41:12 even with 'good' brands like sandisk and samsung? Aug 18 11:41:16 yes Aug 18 11:41:32 how do you know the quirk wasn't in your controller? Aug 18 11:41:34 e.g. pandaboard wont boot with some sandisk Aug 18 11:41:40 it just does not recognize them Aug 18 11:41:53 hmm, haven't seen that Aug 18 11:42:04 i cannot say what exactly it is, but i know there is an issue there Aug 18 11:42:18 probably due to cutting corners at either the sd controller or on the card itself Aug 18 11:43:39 all my sd cards have at least one corner cut Aug 18 11:58:08 meh.. blew a fuse... Aug 18 11:58:13 and it's not an electronic type Aug 18 11:58:20 no ups? Aug 18 11:58:58 the individually fused power plugs we have in britain have some advantages Aug 18 11:59:42 Hey all. Does anyone know if there's a single board computer smaller than the Pi/Bone? Ideally one without video/audio/ethernet Aug 18 11:59:47 Smaller the better. Aug 18 12:00:02 how much cpu power do you need? Aug 18 12:01:20 I'd hope for >400Mhz/128MB ram Aug 18 12:01:29 but Somewhere around that mark would be OK I think Aug 18 12:04:05 narcos: dx.com Aug 18 12:04:13 Or Aug 18 12:04:24 http://shop.8devices.com/carambola Aug 18 12:04:40 Does not however have 128M Aug 18 12:05:00 Great! I'm checking those links out Aug 18 12:05:26 That carambola has WiFi too, brilliant. Aug 18 12:05:30 http://dx.com/p/m2a-android-4-0-network-media-player-w-wi-fi-hdmi-usb-black-4gb-1gb-ram-147979 Aug 18 12:05:36 Foir example Aug 18 12:06:02 I dunno if there are similar ones with more RAM Aug 18 12:07:15 My overall requirements are: very small, particularly flat (which helps of Ethernet/video/etc are not present), WiFi, USB powered, USB hub (two pref). Aug 18 12:07:22 mru: i usually dont need one Aug 18 12:07:42 I don't usually need one either Aug 18 12:07:50 but when I do, it's a damn nice thing to have Aug 18 12:08:14 well.. i have to rebuild my fileserver somewhen soon Aug 18 12:08:21 will buy an apc with the rest Aug 18 12:08:53 I'm pleased with mine so far Aug 18 12:09:55 Do you know if there are any 'build your own' single board computer shops? i.e. I select from a list which hardare options I want ? Aug 18 12:10:11 Generally not Aug 18 12:10:12 that would get expensive Aug 18 12:10:15 I guess half way between a stock unit, and paying for a completely custom unit Aug 18 12:10:18 Simply as mass production kills it Aug 18 12:10:27 Yeah I guess. Aug 18 12:10:40 In principle - sure, it's possible Aug 18 12:10:44 the 'custom' laptops you can order are actually not all that custom Aug 18 12:10:48 Though it tends to have issues Aug 18 12:11:00 guess why some options are tied Aug 18 12:11:06 For example - if you don't want wifi - the board area will still be there. Aug 18 12:11:18 weird stuff like you can't have extra ram without the large ssd Aug 18 12:11:18 ah ok Aug 18 12:13:36 narcos: even if you reuse cpu+ram+flash layout, it's still a day or two of work to get everything else done you'd want. and it's all manual labor that you cannot really automate Aug 18 12:14:23
