[00:18:18] <Casper> rue_shop2: rpm... who knows, I can't find the info anywhere, so hard to say, and I'm trying to avoid piston (I don,t have the tools to machine it)
[01:15:44] <rue_shop2> you dont need to machine a piston
[01:24:10] <theBear> you do if you don't have something round
[02:57:27] <Enma_Hinobara> Grar!
[02:58:13] <Enma_Hinobara> Just discovered by trial and error that you have to enable the interrupt for the timer to allow it to trigger the ADC
[03:01:29] <Enma_Hinobara> Actually it's weirder than that. You have to enable the interrupt to make it trigger more than once
[05:46:48] <molavy> hi
[05:47:13] <molavy> where can i find which image sensor used in which mobile phone
[05:47:15] <molavy> ?
[05:48:00] <molavy> i find buy some image sensors but i can't find their with its name
[05:51:04] <molavy> i what find desired image sensor name then find which mobile phone used that , then go to Cell Phone Repair and buy it ,i should say please give me Nokia n8 image module
[05:51:37] <molavy> because they don't know if it tell please give me ov3642 image sensor
[05:52:10] <molavy> any idea?
[05:58:05] <molavy> there is really no idea?
[05:58:56] <molavy> any idea?
[10:11:23] <mark4> anyone here using AS6 for arm development
[10:11:24] <mark4> ?
[10:16:02] <mark4> how do you create an arm assembler project. create new project in as 6 only has the ability to create an assembler project for avr. wtf
[10:18:33] <specing> vim + gcc + gdb over openOCD ftw
[10:19:04] <mark4> how about not helping. that would be more help
[10:21:11] <mark4> can anyone with a clue about doing arm development in AS6 tell me how to create an ARM project (i already have the code, i just need to compile and ***DEBUG*** it)
[10:22:03] <mark4> i am specifically looking for a arm debugger thats NOT gdb or is gdb with an actual usable interface
[10:22:31] <OndraSter> abcminiuser, ^
[10:22:36] <specing> how come gdb is not usable?
[10:22:44] <OndraSter> specing, some of us prefer GUI
[10:22:52] <OndraSter> not TUI
[10:22:54] <specing> theres the ddd front-end
[10:22:56] <abcminiuser> Heyo
[10:23:01] <OndraSter> heya abcminiuser
[10:23:07] * abcminiuser is preping for business trip Monday, here on and off
[10:23:10] <mark4> atmel is pushing as6 as having arm support. packaging a totally disconnected version of gcc is not adding arm support to as6
[10:23:36] <Tom_itx> abcminiuser, got your penstripe suit n tie all in order?
[10:23:37] <mark4> specing, gdb/ddd is not helpful to me. i cannot see everything i need to see in the way i need to see it in gdb
[10:23:55] <abcminiuser> Hah pretty much
[10:23:58] <mark4> ive only been fighting this for 2 weeks. im looking for an alternative to gdb. ANY alternative to ddd
[10:24:31] <OndraSter> abcminiuser might (should/could) know :P
[10:24:39] <OndraSter> I have never done ARM in AS6
[10:24:54] <mark4> i dont care if its gdb on the inside as long as it has a usable user interface that allows me to see all the things i need to see in the way i need to see them.
[10:25:30] <mark4> there does not seem to be ANY arm development integrated into AS6 at all
[10:25:32] <mark4> NONE
[10:25:35] <mark4> which means atmel lied
[10:25:36] <abcminiuser> Studio 6 in a VM?
[10:25:47] <abcminiuser> mark4, what?
[10:25:49] <mark4> im running AS6 in a vm
[10:25:56] <abcminiuser> So what are you missing?
[10:25:59] <mark4> abcminiuser, there is no "Create arm project"
[10:26:07] <abcminiuser> Create a C++ project
[10:26:09] <mark4> create assembler project has "avr assembler" only
[10:26:10] <mark4> no
[10:26:10] <abcminiuser> ARM isn't a language
[10:26:15] <mark4> its NOT a c++ project
[10:26:18] <mark4> its 100% assembler
[10:26:24] <abcminiuser> Ah, create a C project, add a .S file and use GAS
[10:26:25] <mark4> arm is a language
[10:26:36] <abcminiuser> ARM is an architecture with an instruction set
[10:26:38] <abcminiuser> Use GAS
[10:27:11] <mark4> and is the debug integrated into the IDE?
[10:27:20] <abcminiuser> Jupp
[10:27:26] <mark4> or does it just spawn an instance of some other interface
[10:27:30] <abcminiuser> Have you actually tried using it?
[10:27:48] <mark4> i launched it. i said create new project. i said assembler. i saw avr as the only option
[10:28:08] <abcminiuser> That's the Atmel ancient in-house assembler, for legacy reasons
[10:28:18] <abcminiuser> AVR, UC3 and SAM can all use GNU-GAS
[10:28:49] <mark4> im actually trying to get the FUCK away from all GNU based development tools. as far the fuck away from them as i can get
[10:29:21] <specing> This is getting funnier by the minute
[10:29:41] <vsync_> hahaha
[10:30:39] * abcminiuser head asplodes
[10:30:48] <abcminiuser> Ok, very funny
[10:30:52] <abcminiuser> Who is it, Tom?
[10:31:03] <mark4> tried to create a c++ project. got to device selection and as6 crashed
[10:31:35] <mark4> ok uninstalling. this is as much a nightmare as im trying to get away from
[10:31:42] <OndraSter> lol
[10:32:41] <vsync_> gnu is the devil's spawn!
[10:32:44] <specing> Oh no, he is stuck with GNU tools. Poor mark4
[10:32:49] <OndraSter> :D
[10:32:54] <abcminiuser> I really don't have time for jokes today
[10:33:42] <specing> Where are you going abcminiuser ?
[10:33:49] <abcminiuser> Germany
[10:33:59] <abcminiuser> Multi-million dollar customer needs project assistance
[10:34:03] <abcminiuser> So need to prep
[10:34:05] <specing> city?
[10:34:11] <abcminiuser> Heilbrunn
[10:34:19] <Tom_itx> more important than US!
[10:34:20] <Tom_itx> ?
[10:34:25] <OndraSter> oo
[10:34:26] <OndraSter> germany
[10:34:26] <specing> Heil burn!!
[10:34:27] <OndraSter> so close
[10:34:48] <abcminiuser> I'm back there again for a slightly smaller customer in a month too
[10:34:50] <abcminiuser> Madness
[10:34:56] <Tom_itx> they trust you with that many dollarz?
[10:35:08] <OndraSter> haha
[10:35:18] <abcminiuser> Heh
[10:35:47] <Tom_itx> no pressure
[10:37:56] <Tom_itx> did they issue a Ferarri for you to show up in?
[10:38:25] <specing> he has a private heli
[10:39:11] <abcminiuser> Hah, it's not that unusual
[10:39:20] <abcminiuser> I've been supporting them for months, so it's not too much pressure
[10:39:33] <abcminiuser> Still, when you fly in on-site, you need to know your stuff
[10:39:47] <Tom_itx> meh just google it
[10:40:39] <Tom_itx> then there's us if you really get stuck
[10:41:38] <specing> yeah, though they don't have time for googling :)
[10:41:51] <Tom_itx> ok enough messin.. time to get something done here
[17:25:51] <Hexorg> Hello all
[17:27:14] <Casper> o/
[17:31:14] <Hexorg> o/
[17:33:36] <Tom_itx> \o/
[17:34:03] <vsync_> _o\
[17:34:09] <vsync_> _o/
[17:34:27] <vsync_> do the avr!
[17:34:52] <Casper> https://www.dropbox.com/s/jr048wxc2cl4usp/2013-09-07%2016.11.30.jpg ← cute
[17:35:56] <Fornaxian> looks almost like a motorcycle trailer.
[17:36:20] <Hexorg> lol
[17:36:25] <vsync_> looks almost like a woman or someone with a high self esteem and poor judgement
[17:36:40] <Hexorg> has anyone made home PCBs here?
[17:36:46] <vsync_> to be sexually corrent, could also be a mix of all of the above
[17:36:54] <Fornaxian> http://www.microchip.com/TechDocByProduct.aspx
[17:37:06] <Fornaxian> Hexorg, yes.
[17:37:07] <Casper> you know, we may see more and more of that with those new electric car
[17:37:17] <Casper> that would actually be the genset for them for extended range :D
[17:38:35] <Fornaxian> http://www.trekkertrailer.com/gallery/
[17:38:44] <Fornaxian> there's the trailer.
[17:38:45] <vsync_> Casper: electric cars will be bs until the battery tech evolves up to a point where they become way more efficient when charging
[17:38:57] <Hexorg> Fornaxian, Does anyone have any advice about checking for shorts / opens on etched PCBs?
[17:39:00] <vsync_> e.g. it can store all of the energy when breaking
[17:39:15] <Fornaxian> Hexorg, meter.
[17:39:21] <Fornaxian> and/or microscope.
[17:39:52] <Casper> vsync_: batts are quite efficient (97% for lithium), chargers can be very efficient (80% would be a low end efficiency, 90-95 is doable)
[17:40:05] <Casper> but energy storage and cost and lifespan is the issue
[17:40:26] <vsync_> when it can store all of the energy out of a break it will be efficient
[17:40:37] <vsync_> now, it cannot. You cannot possibly charge a lithium with a current that high
[17:40:50] <Hexorg> Fornaxian, yeah.... Meter failed me 2 times in the past day lol I guess I should invest in the oScope
[17:41:33] <Fornaxian> Hexorg, not sure how you will use an oscope to check traces, other than using it an a high end meter.
[17:41:46] <vsync_> you could however, store the energy into a capacitor. I think buses here do that actually
[17:41:55] <vsync_> at least the "green buses"
[17:41:56] <Hexorg> Fornaxian, Brr.. Brain hickup. I ment uScope (microscope)
[17:41:59] <Fornaxian> massive honkin flywheel!
[17:42:08] <vsync_> Volvo is actually doing a flywheel
[17:42:12] <Fornaxian> oh?
[17:42:16] <vsync_> they call it hmm... Meh. I cannot remember
[17:42:29] <vsync_> Volvo KERS
[17:42:37] <Fornaxian> I've thought of doing that for years...dump into flywheel then slowly extract it to charge battery/cap bank.
[17:42:48] <vsync_> no it doesn't do that i'm afraid
[17:42:53] <Casper> vsync_: caps don't store enought energy, bus use lithium or hydrolic
[17:43:12] <vsync_> I think they use a huge capacitor bank here. So I've heard
[17:43:17] <vsync_> it's located on top of the bus
[17:43:24] <Casper> most probably a battery pack
[17:43:29] <vsync_> it only uses it for the initial acceleration short after the break
[17:43:31] <Casper> never hear of any maker that use caps
[17:43:51] <Fornaxian> aahh..they store up as rotary kinetic energy then use that for acceleration after stop.
[17:44:09] <vsync_> Fornaxian: yes, it's hooked to the drivetrain, it gets pulled off of it when breaking
[17:44:18] <Fornaxian> looking at pic of it now.
[17:44:21] <vsync_> and when acceleration is applied it hooks it back to the drivetrain
[17:44:24] <Fornaxian> http://www.motortrend.com/roadtests/sedans/1307_volvo_s60_flywheel_kers_prototype_first_drive/
[17:44:44] <vsync_> Casper: with a quick google, found some capacitor bank bus stuff
[17:45:53] <vsync_> the thing with it that it's so much faster a charge than lithium or any battery available
[17:46:00] <vsync_> so I see why not
[17:46:03] <vsync_> Fornaxian: yep
[17:46:43] <vsync_> but i think it's not in production yet, cause there was some minor setbacks... I think their initial flywheel design was too heavy
[17:47:46] <Fornaxian> yeah.
[17:47:51] <Fornaxian> 600 pounds or some such.
[17:48:03] <Fornaxian> but looks like new volvo vehicles are built with a special mount for it.
[17:48:13] <Fornaxian> for either that or an electrical regen breaking system...from that article.
[17:49:39] <vsync_> yeah alright
[17:50:00] <vsync_> all in all it's quite a fascinating idea
[17:50:40] <vsync_> because with the current battery tech electric cars are really out of the question. Especially here up north, where you'd first need to warm the battery pack...
[17:50:47] <vsync_> and even in warmer places it's iffy at best
[17:51:11] <Casper> vsync_: manufacturer or blog?
[17:51:41] <Fornaxian> yeah. here they have pack warmers.
[17:52:00] <vsync_> well Casper for instance you can check out capabus
[17:52:24] <vsync_> But I'm quite sure they're caps they use in some of the buses here, because it's only the breaking energy they store
[17:52:30] <vsync_> to store that into a lithium, would be stupid
[17:52:56] <Fornaxian> new supercap technology is getting to be amazing.
[17:53:34] <vsync_> Fornaxian: well, pretty much every year some tech lab comes up with a "revolutionary battery tech"
[17:54:26] <vsync_> but the fact of the matter is that no big steps have been made concerning energy density since li-pos, and well safer stuff as in li-fe-po and variants, like a123
[17:54:53] <vsync_> and even they have drawbacks so :(
[17:55:26] <vsync_> in commercial products, that is
[17:55:42] <Casper> vsync_: do the math on the quantity of farad required to store enought energy to move a bus
[17:56:51] <vsync_> yes, but, again for instance, the capabus runs on supercaps
[17:56:56] <Casper> so?
[17:56:59] <vsync_> so?
[17:57:02] <Casper> supercap ain't great
[17:57:19] <vsync_> do the math, to store the energy generated in breaking the bus into a lithium cell?
[17:57:28] <vsync_> How much do you think it'll charge?
[17:57:29] <Casper> I did
[17:59:19] <Casper> capabus... sound good in theory, in practice it's bad... it need an infrastructure that is very costly, won't be commercially viable
[18:00:02] <vsync_> Yes well
[18:00:19] <vsync_> you need proof? Here's your proof from the manufacturer, stating that the brake energy is stored in CAPS
[18:00:23] <vsync_> http://www.mantruckandbus.com/en/innovation___competence/alternative_drive_systems/hybrid_drive/Hybrid.html
[18:00:32] <Casper> vsync_: I'm reading wikipedia
[18:00:40] <vsync_> wikipedia, the source of information(tm)
[18:00:42] <Casper> and in 2012 it was still experimental
[18:01:06] <Casper> it does however show promises
[18:01:15] <vsync_> Well
[18:01:25] <vsync_> manufacturer's site says, it was already deployed in 2010
[18:01:35] <vsync_> So i'm pretty sure it's what they use here.
[18:01:47] <vsync_> It's not all of the public transportation, just some "green buses"
[18:02:08] <vsync_> it'd be really stupid to store braking energy into lithium. Really. It would charge, pretty much nothing
[18:02:31] <vsync_> because it's a short burst, the cap can store way more
[18:02:45] <vsync_> as it has no generator to charge up a battery bank
[18:04:54] <vsync_> the buses over here, it's a huge bank located on the roof of the bus. As shown in the pictures over at MAN's site
