00:17.44g1powermac_PBso what does everything of the logo? http://www.g1powermac.com/thisoldgadgetlogosmall.jpg
00:22.23SpeedEvilNeeds more puppies.
00:22.51g1powermac_PBwhat the heck did I type. . . s/everything/everyone think
00:23.14g1powermac_PBreally wonders about the typos I make
00:23.28SpeedEvilAt reasonable scales, the traces are way too busy
00:23.51SpeedEvilMake it a DIP8 or something, with one or two tracks
00:24.11g1powermac_PBhmm
00:24.25SpeedEvilAlso - it won't work on black backgrounds.
00:24.37SpeedEvilBut that's always a problem.
00:24.42g1powermac_PByea
00:24.57g1powermac_PBI don't have to worry too much about black backgrounds
00:27.31SpeedEvilOr maybe a single trace, going up to a couple of pads on the left, with a resistor symbol -/\/\- between them.
00:27.47SpeedEvilOr a lightbulb
00:30.09g1powermac_PBhmm, that'd be interesting
00:36.32RobotGuyg1powermac_PB: I just finished the design for the femur. :)
00:37.08g1powermac_PBkewl
00:39.19SpeedEvilRobotGuy: remember - the leg bone's connected to the kneebone...
00:39.37RobotGuySpiders don't have knees, as far as I know. :P

00:43.32g1powermac_PBnice
00:45.29SpeedEvil<PROTECTED>
00:59.17RobotGuyg1powermac_PB: I just completed a second femur.  Now, on to the tibia!
01:01.30SpeedEvilDo you have pics of this thing?
01:11.01RobotGuySpeedEvil: Not yet.  I have to get the tibia designed first.
02:49.16RobotGuyHmmmmm, having a bit of trouble with the tibia.

14:37.59prpplaguesolar: something like that
14:38.43g1powermacmorning prpplague
14:39.00prpplaguesolar: advanced warning, i'm in a foul mood, so if i sound cross, don't take it personallly
14:39.21solarprpplague: ok two things. First I've updated that ledctl yet again. handles timer events. and gives better return code.
14:39.48prpplaguesolar: lovely
14:39.59solarsecond: having a bit of a driver problem. Which you might be interested in.
14:40.01solarhttp://dev.gentoo.org/~solar/embedded/tct/s3c2410-leds.c
14:40.19chouimat|workmorning
14:40.51solarin this file. I'm trying to hook so we can take advantage of CONFIG_LEDS_CPUto give us another option in the "triggers" file.
14:41.28g1powermacprpplague, anything new with the zipit?
14:41.47prpplagueg1powermac: sorry no, gonna send your unit back on friday
14:41.55g1powermack
14:42.37prpplaguesolar: give me a second to look at the file and come up to speed
14:45.21prpplaguesolar: okie dokie, what kind of a problem you looking at?
14:47.32solarprpplague: I'm hitting this error and I don't know why. http://rafb.net/p/allwMo18.html (leds_event) is clearly defined in arch/arm/kernel/time.c
14:50.42prpplaguesolar: looking
14:51.30*** join/#edev CosmicPenguin (n=nobody@163.181.251.103)
14:51.31*** mode/#edev [+o CosmicPenguin] by ChanServ
14:51.34solarprpplague: then I'm looking for some magic outb() numbers after this initial problem
14:55.26prpplaguesolar: have a look at the mach-pxa directory, you can see how they setup the leds there with the leds.c, for your init function you need to make a connection between the generic led assignment and your specific function
14:56.19prpplaguesolar: nm, you have that
14:56.27prpplaguesolar: slow this morning
14:56.35prpplaguecontinues to look
15:02.47prpplaguesolar: hmm interesting, even if you had the leds not turned on the define should still be there
15:03.11prpplaguesolar: can you pastebin your makefile for the arch/arm/mach-s3c2410 directory?
15:03.59solaryeah. But all I add there is this. obj-$(CONFIG_LEDS)+= s3c2410-leds.o
15:04.36solarhttp://rafb.net/p/0CpSTT84.html (otherwise)
15:05.43solarhrmm. I might see the problem
15:06.30solarI had it defined two times in there. One on the tct line. If I change it to just LEDS it compiles. But I have a feeling the leds are in a disabled state.
15:07.30solarand CONFIG_LEDS is not actually defined. http://rafb.net/p/7yhSm848.html
15:11.39prpplaguesolar: yea that would do the trick with the duplicate entry
15:12.42solarproblem now is that CONFIG_LEDS can't be defined afaict
15:13.20solaroh well. I'll get it. thanks
15:14.38prpplaguesolar: the comparision for that is based on the string, basically its comparing CONFIG_LEDS to CONFIG_LEDS_*
15:15.21prpplaguesolar: as long as something with CONFIG_LEDS_ is defined, it will be considered true
15:17.34solarbut it seems it's not
15:17.48solarI could go hack up the defines in kernel/timer.c
15:18.05solarbut I have a feeling that something that I've yet to find defines it.
15:19.35prpplaguesolar: i'd check the pxa dir to see they have something there
15:20.20solarmach-footbridge seems to be where the arm-leds support started.
15:23.05prpplaguechecks the .25 kernel
15:23.51solaroh I id some more cleanups in mach-tct-hammer.c several routines were being built in despite user options.
15:24.13solarhttp://dev.gentoo.org/~solar/embedded/tct/mach-tct_hammer.c
15:25.12solarand if CONFIG_LEDS_TRIGGER_HEARTBEAT is set. It switches led0 to default to heartbeat vs timer.
15:25.20prpplaguecute
15:25.58prpplaguesolar: rmk generally complains about alot of ifdef's in the machine file
15:26.44prpplaguesolar: i don't see any location where CONFIG_LEDS is explicitly declared
15:27.09prpplaguesolar: ahh found it
15:27.13prpplaguesolar: one sec looking
15:27.13solarprpplague: me either. But I'm looking on my slug and I see it has none timer heartbeat [cpu]
15:27.52solarI saw somewhere else somebody submitted a patch to one of sjhill's drivers to another hich make nand-disk a trigger
15:28.39prpplaguesolar: arch/arm/Kconfig
15:28.54prpplaguesolar: need to add the s3c2410 there in the leds section
15:33.02solargot it. nice.
15:33.12solarnow I'm ready to move on the gpios' itself.
15:33.30solarthat can come later.
15:35.07prpplaguesolar: good deal
15:35.29prpplaguemakes a note that a patch for that is needed
15:43.32solarprpplague: if you are going to hack up a patch. I'm rather fond of netwinder-hw.c and how they have a gpio_modify_op()
15:44.02prpplaguesolar: sorry i meant for the leds support for s3c24xx
15:45.52solarfor your .25 branch? You should be able to simply snag the mach one I just posted. Some of the defines can probably be moved into macros elsewhere to keep rmk happy.
15:46.57solarwhats neat is on my cellphone we have the beeper/vibrator tied into a led. So you can do heartbeats on it etc.
15:47.01prpplaguesolar: yea, just making notes for stuff to submit for 2.6.27-rc4/5
15:47.19solarI looked into trying to tie in the beeper to led3 but confused myself

16:08.00SpeedEvilI've told you the solution. Ask to be added to sudoers. Knowing the quality of tech support, they'd prolly do it :)

16:11.14RobotGuyinsearchof: Greetings
16:11.15insearchofI have a mac question for you
16:11.44sunrunner20SpeedEvil: I'll tell  you what
16:11.57sunrunner20the head of tech support is going to hear about this one
16:12.04SpeedEvilProbably wise.
16:12.18SpeedEvilPeople need to learn to escalate if they don't understand
16:12.24RobotGuysunrunner20: Have you requested to speak with a supervisor about this?
16:12.50RobotGuysunrunner20: They won't generally escalate unless you force them to by asking to speak to a supervisor.
16:13.07sunrunner20I got moved up
16:13.19sunrunner20and the idiot set my user to www-data instead of the group
16:13.31RobotGuysunrunner20: Getting irate with whomever you are speaking to never does anyone any good.
16:13.45sunrunner20RobotGuy: which is why i'm getting irate here :)
16:14.05RobotGuysunrunner20: Getting irate here will just get you put on ignore (at least by me).
16:14.10sunrunner20oh
16:14.18sunrunner20well i'm not trying to bash them too hard fyi
16:14.24sunrunner20I'm just really annoyed
16:14.37RobotGuysunrunner20: Does this have something to do with embedded systems?
16:14.47sunrunner20good point

16:16.26*** join/#edev sjhill_ (n=sjhill@real.realitydiluted.com)
16:16.32sunrunner20anyway, I'm going to start documenting my GCN powered GBA project
16:17.36CosmicPenguinWhat does linux have to do with embedded systems?
16:17.46SpeedEvilSome use it
16:17.55SpeedEvilAs some use windows 95, or GEM.
16:18.18RobotGuyg1powermac: I have come to the conclusion that I am going to have to design legs using micro servos to fit the new mini arachnid body I designed.
16:19.44sunrunner20RobotGuy: what about using springs + wire line
16:19.52sunrunner20would be much stronger
16:20.15RobotGuysunrunner20: Stronger for what?
16:20.32sunrunner20in general
16:20.52RobotGuysunrunner20: it does not apply to my application for this eight legged robot.
16:21.07sunrunner20got a cad/pic?
16:21.23RobotGuysunrunner20: Of course I do. Full 3D model.
16:21.36sunrunner20rendered?
16:21.50RobotGuysunrunner20: Not rendered, but plenty good enough.
16:22.14sunrunner20because chances are servo's arn't going to be very strong
16:22.20RobotGuyI could add a rendered version to my 3D PDF.
16:22.31RobotGuysunrunner20: Have you built a robot?
16:22.59sunrunner20I've handled older servos
16:23.11RobotGuyThat doesn't answer my question.
16:23.12sunrunner20and while the torqe is more than adique
16:24.09RobotGuyI'm dealing with brand new servos, mostly Hitec.
16:24.22sunrunner20pysically they are rather weak
16:24.37RobotGuysunrunner20: That depends on the servo.
16:26.08RobotGuyI will eventually have Hammer controlling a multi-jointed arm on W.A.L.T.E.R., my rover. The servos are no problem so far, but I am sure I will have to upgrade eventually to handle the payload weight I want to lift.

18:18.06SpeedEvilali_as: you need a lot of LEDs
18:18.22sunrunner20depends
18:18.37sunrunner20you can overdrive them

18:20.36sunrunner20some leds handle it better than others
18:20.49sunrunner20I know nothing on how white's handle over driving
18:21.13ali_asThere was a nuts article on hacking UV from a blue led somewhere.
18:21.37sunrunner20getting UV wavelenght from blue?
18:21.42sunrunner20which UV?
18:21.46ali_asOverdrive one of the old SiC blue leds using very short pulses and a spike in the UV region appears.
18:22.58ali_asI don't think it was deep or very bright, nowerdays anything around 400nm seems to be classed as UV.
18:25.42ali_ashttp://members.misty.com/don/ledbl.html
18:25.50ali_as385 to 390nm
18:26.13ali_asFrom a broadband blue 450nm led.  GaN is best though, I was wrong about SiC.
18:30.56RobotGuySpeaking of cameras..  What is an easy to get camera module, like the OV6620? Or is it just better to buy a camera that uses that module?
18:31.43ds2is that the low res one? seem to recall someone selling it in singles.. mighthave been a CMU vision related project
18:33.27sunrunner20sparkfun sells camera modules
18:33.45RobotGuyI'm actually looking for a small module that uses the OV6620 or similar sensor, but really would like something with at least 1.3 MPixel resolution.
18:33.53RobotGuysunrunner20: I know.
18:34.05RobotGuysunrunner20: The problem is getting documentation.
18:34.23ali_assunrunner20, btw you'll need a heatsink for the led I think or it will overheat.
18:34.26sunrunner20you probally won't get it legitamatly
18:34.41ali_asRobotGuy, 1.3Mpixel at what frame rate?
18:34.45sunrunner20ali_as: a peice of Cu sheet will work :)
18:35.22RobotGuyali_as: Something that can do close to 30 fps (15 - 30).
18:35.54RobotGuysunrunner20: Why do you think that>
18:36.04ali_asI don't know about copper sheet, I'd think a block would be better.
18:36.37RobotGuysunrunner20: Why do you think I couldn't get data legitimately?
18:36.48ds2RobotGuy: what are you trying to do with the sensor?
18:36.54sunrunner20RobotGuy: CMOS sensors have a lot of propitary technology inside of them
18:36.58ali_asI looked at USB webcams and all the 1.3Mpixel models seem to use the same sensor.
18:37.08RobotGuyds2: It's a camera..  Imaging, vision, etc.
18:37.12ali_asI think a micron.
18:37.24ds2RobotGuy: why wouldn't a USB interface one work?
18:37.49ali_asThey all do 1.3Mpixel, and they all do 30Hz, but they don't do 1.3Mpixel and 30 Hz at the same time.
18:37.54RobotGuyds2: It would, for some applications, but not sure it would work well for what I want to do.
18:39.03RobotGuyds2: For USB, it would have to be supported by Linux.
18:40.04RobotGuySpecifically, ARM Linux, as in Hammer.
18:40.25RobotGuyI just don't want something big
18:40.44solarwould be shocked if you get more than 2fps
18:41.00sunrunner20hrm
18:41.07RobotGuysolar: Why so slow?
18:41.26sunrunner20raw cpu power in the hammer thats why
18:41.35solarmem. You need to offload them to somewhere fast enough
18:42.06RobotGuysolar: I'm not talking about driving a camera directly from Hammer.  That was just an example for USB. :)
18:42.56RobotGuywishes for an S3C2440A based camera board.

18:44.13RobotGuysolar: Do you have a link to the specific one you mean?
18:45.19solarRobotGuy: I can search.. Sec.
18:46.03RobotGuysunrunner20: I am not conserned about the proprietary technology inside a sensor. I am concerned with the hardware interface.
18:46.35RobotGuytries to find it on the Logitech site
18:47.28adyerRobotGuy: most low res camera modules have an 8/10 bit low voltage TTL interface for data + syncs and clock signals and an I2C bus for register settings
18:48.17RobotGuyadyer: I don't want low res though.  Unless you consider 1.3 MPixel low res.
18:48.37adyerRobotGuy: 1.3MPixel is low res these days
18:49.19adyerRobotGuy: fancier camera modules use variations on LVDS for their interface
18:49.22RobotGuyadyer: I want something that will give clean, clear images and video.
18:50.03ali_asDon't higher res modules usually use cameralink or gigE interfaces?
18:50.19ds2RobotGuy: that shouldn't be too hard... the biggest question is $$$$
18:50.48sunrunner20I've got a few people I could probally ask questions...
18:51.15RobotGuyds2: What kind of price would what I am asking for be?
18:51.24ds2RobotGuy: might be as much as $100
18:51.42RobotGuyds2: For a module or a sensor?
18:51.43adyerds2: 1.3 mpixel modules can be gotten for $5-$7 through distribution in moderate qty - this is sensor pcb and plactic lens
18:51.53ds2RobotGuy: a USB camera w/1.3M
18:52.03ds2adyer: what kind of interface?
18:52.08RobotGuyds2: I do not want USB.
18:52.08adyerds2: ttl
18:52.18ds2I can get USB cameras for $5-$7 but they are 640x480 :(
18:52.19ali_asWhat kind of full resolution framerate?
18:52.31sunrunner20YAAAAAAAAAAA
18:52.35sunrunner20they fixed it

18:53.01RobotGuyNobody seems to be listening. :(
18:53.56adyerds2: lol, full docs are never included, you have to beg - the module we're looking at is based on ov7725, 640x480 supposedly at 30 Hz
18:55.03adyerds2: i'm supposed to be writing the dma code for our fpga right now, but i'm slacking
18:55.26ali_asWhat is the fpga doing?
18:56.09adyerali_as: LCD control, frame buffer, scaling, PCI, some minimal 3d stuff
18:56.27ali_asCool, what is the application?
18:56.46adyerali_as: bartop games and jukebox
18:57.01sunrunner20hrm

19:01.13ali_as200 quid!
19:01.33ali_asYou could buy a complete pc for that.
19:01.46sunrunner20no
19:01.57sunrunner20you could fit 10 or so of those in a complete pc
19:02.25sunrunner20:p
19:02.39sunrunner20its 120mm square :)
19:02.54ali_asAbout 300 quid here will buy a pc, not including the monitor which you'd need.
19:03.13sunrunner20aye
19:03.14ali_asNot a great PC but then neither is the via.
19:03.22sunrunner20i can build a machine for that too
19:03.42sunrunner20but your paying a premium for the size
19:03.45ali_asAn FPGA could drive an LCD directly.
19:04.06sunrunner20so can that board :)
19:04.55ali_asHow?
19:05.33sunrunner20it has the standard interface
19:05.37sunrunner20its lvds or whatever
19:06.07RobotGuyAn FPGA could handle a camera directly too.
19:06.17sunrunner20ffs
19:06.19magnetronanyone know any FPGAs designed for PC interaction? i want to use it to speed up computations
19:06.24sunrunner20an fpga can handle amlost anything
19:06.54RobotGuyIt's a matter of programming the FPGA to do what you want and interface the way you want it to.
19:07.08sunrunner20magnetron: there are PCI express evaluation kits
19:07.12ali_asSays LVDS DVI interface, needs adaptor, which board are you looking at scpficially?
19:07.45ali_asI've only been looking at the first board in the list, I didn't see the others.
19:07.55sunrunner20they should all have it
19:08.05sunrunner20its part of the platform iirc
19:08.06adyerali_as: IIRC there's a little daughtercard to hook an LVDS display to a via board, it supports parallel lvttl native
19:08.23ali_asDVI isn't a direct to LCD interface though.
19:08.55ali_asYou'd need a full blown monitor no?
19:09.07sunrunner20no
19:09.22ali_asmagnetron, what are you planning to speed up?
19:09.46magnetronali_as: "stuff"
19:09.47magnetron:D
19:10.09ali_asYou want to bruteforce a linux password file ;P
19:10.22magnetronali_as: actually it was WPA rainbow tables
19:10.41ali_asAhhh.  I thought rainbow tables needed a lot of memory.
19:10.53ali_asOr is that just once they have been spat out?
19:10.54magnetronhard drives are cheap.
19:11.15sunrunner20they don't need memory
19:11.20sunrunner20they need disk space more than anything
19:11.37ali_asTo use certainly,but how about create?
19:11.37sunrunner20an FPGA would be usefull for brute forceing
19:11.59sunrunner20useless
19:12.15sunrunner20my quad core can create tables faster than my HDD can write them to disk :\
19:12.28ali_asI'm not farmiliar with rainbow table math, just that its a time memory tradeoff.
19:14.44sunrunner20it would be more cost effective to build a high end system than to buy a dev board to just do rainbow tables
19:15.23ali_asFPGAs take forever to produce an efficiant softdesign.
19:15.45magnetronsunrunner20: what would be a good way of communicating with the PC? ethernet?
19:16.01sunrunner20PCI express bus
19:16.12sunrunner20would be the fastest
19:16.18ali_asIs this channel logged to public access?
19:16.25magnetronit doesn't have to be fast, sunrunner20
19:16.29magnetronali_as: so?
19:16.32sunrunner20yea it oes
19:16.35sunrunner20*does
19:16.45sunrunner20if your generating rainbow tables it does
19:17.35sunrunner20and tbh
19:17.39sunrunner20I've always though
19:17.51sunrunner20there should be a FPGA sitting on a bus somewhere in a modern PC
19:18.14sunrunner20changing itself as the computers task changes
19:19.02ali_asReconfigureable computing.
19:19.29sunrunner20for high performance stuff only
19:19.54magnetronsunrunner20: ok, for every network name i generate a rainbow table it will require a few GBs. say 5 GB. how long should it take to genereate it? within an hour, hopefully. that's just a few MB/s
19:20.18sunrunner20I don't know how fast the FPGA will generate it
19:20.47magnetronan hour would be extremely good
19:21.17sunrunner20it will be orders of magnitude faster than a PC
19:21.29sunrunner20if you code it right
19:21.30ali_asI think you'd have to work very hard to make an FPGA design that would beat a fast PC.
19:21.40sunrunner20not really
19:21.40magnetronyes, but the computational result will be fairly small
19:22.04ali_asUnless the math is very simple boolean algebra.
19:22.24magnetronthe computations are very iterative. i only need the end result.

23:07.48RobotGuyThanks
23:10.28RobotGuysolar: The Orbit AF?
23:12.34solarRobotGuy: I don't recall what res I was working with before. It was just a pretty easy one to get going under linux and worked great with motion etc..
23:13.12RobotGuyThat sounds like it could be the Orbit AF.  Which Linux driver?
23:20.00solarRobotGuy: http://www.quickcamteam.net/hcl/linux/logitech-webcams
23:20.21RobotGuylooks
23:20.23solarI've been debating picking up another one of these cuz they are handy. But I'm a little worried about the nail keeping up
23:21.07solarWe mainly used them before at datacenters. Shove one in the top of a rack. Make a little webpage and watch your noc 24x7

23:24.00RobotGuysolar: Thanks for that link! I may get one of the Orbit AF cameras, or a Communicate Deluxe then - supported by the same driver. :D This is great, because I have always liked Logitec stuff.
23:24.32prpplaguesolar hows your eabi testing?
23:25.26solarprpplague: not really been focused on it for the hammer.
23:26.00solarIf it were the SC24[4?]X it might be more fitting cuz then chances are you might have a reason to run X/gpe etc.
23:26.08RobotGuyI wonder if the uvcvideo driver is supported for ARM.  Got to look now. :)
23:29.33prpplaguesolar yea the hammer lacks the flash/ram really for most x stuff
