#emc | Logs for 2006-04-10

[00:00:15] <K4ts> night
[00:00:17] <giacus> G night
[00:00:24] <giacus> giacus is now known as giacus_afk
[00:01:03] <CIA-8> 03cradek 07v2_0_branch * 10emc2/scripts/realtime.in:
[00:01:03] <CIA-8> Unbelievably, sometimes a several-second pause is required to let
[00:01:03] <CIA-8> udev create the /dev entry.
[00:24:48] <CIA-8> 03cradek 07v2_0_branch * 10emc2/src/Makefile: these include files were missing in the /include directory
[00:27:02] <CIA-8> 03cradek 07v2_0_branch * 10emc2/src/hal/Submakefile: needed to install hal.h
[00:30:57] <CIA-8> 03cradek 07v2_0_branch * 10emc2/bin/.cvsignore: ignore halui
[00:32:44] <CIA-8> 03cradek 07HEAD * 10emc2/scripts/realtime.in: sometimes we have to wait for udev to create the /dev entry
[00:33:37] <CIA-8> 03cradek 07HEAD * 10emc2/src/Makefile: these include files were missing in the /include directory
[00:34:07] <CIA-8> 03cradek 07HEAD * 10emc2/src/hal/Submakefile: needed to install hal.h
[00:34:32] <CIA-8> 03cradek 07HEAD * 10emc2/bin/.cvsignore: ignore halgui
[00:36:54] <CIA-8> 03cradek 07HEAD * 10emc2/tcl/tkemc.tcl: remove debug output
[00:37:53] <CIA-8> 03cradek 07v2_0_branch * 10emc2/VERSION: moving TESTING
[00:42:28] <CIA-8> 03cradek 07v2_0_branch * 10emc2/VERSION: Done tagging
[01:23:10] <jepler> cradek: you've been busy
[01:24:17] <cradek> jepler: yep
[01:24:26] <cradek> trying to make a testing release...
[01:24:41] <cradek> jepler: http://timeguy.com/cradek-files/emc/bad-arc.png
[01:27:25] <jepler> eew
[01:27:30] <jepler> I bet I have to abs or something
[01:28:00] <cradek> yeah I bet
[01:28:09] <cradek> some look good, others have the minimum number
[01:31:20] <jepler> fixed?
[01:31:25] <cradek> yay
[01:33:42] <cradek> yep looks great
[01:34:13] <jepler> I'm tempted to hack run-in-place into axis 1.2 and release it again
[01:34:59] <cradek> resist the urge to add unnecessary features to the stable version!
[01:35:11] <jepler> oh right
[01:35:15] <jepler> but this is an important feature
[01:35:46] <cradek> anyone using rip can just as easily use axis 1.3
[01:36:36] <jepler> should I switch axis over to your "cia" script (if I can have a copy)?
[01:36:43] <jepler> it'd be neat to see commits appear in irc
[01:38:01] <CIA-8> 03cradek 07HEAD * 10infrastructure/cvs-server/ (cia log): these scripts are used on the cvs server
[01:38:30] <jepler> I'm looking at 'loginfo', and I notice that there are multiple ALL entries. That works?
[01:38:49] <cradek> yes
[01:38:50] <jepler> (well, clearly it does...)
[01:38:55] <cradek> there can only be one DEFAULT iirc
[01:39:15] <jepler> It was more than one 'axis' that I tried to add
[01:39:29] <jepler> that didn't work; it never crossed my mind that multiple ALLs would.
[01:40:52] <cradek> these arcs look good on my nvidia card
[01:41:40] <jepler> but on software, I wonder if it's too many segments
[01:44:04] <jepler> Is 'sendmail -t' what I want to use?
[01:44:21] <cradek> yes
[01:45:00] <cradek> and try not to laugh at the mess caused by wanting to use sh with no external programs
[01:59:23] <cradek> # If the name ALL appears as a regular expression it is always used
[01:59:24] <cradek> # in addition to the first matching regex or DEFAULT.
[01:59:36] <cradek> so I agree you get only the first matching regexp
[01:59:47] <cradek> I'm also surprised multiple ALLs work...
[02:07:55] <CIA-8> 03jepler 07HEAD * 10axis/setup.py: when not installing bwidget, don't copy its license
[02:08:07] <cradek> whee!
[02:08:30] <jepler> yeah, whee
[02:19:38] <cradek> did you have to hack it a lot?
[02:21:31] <CIA-8> 03jmkasunich 07HEAD * 10emc2/src/module_helper/Submakefile: yet another makefile tweak to work with make version 3.79.1 (on BDI-TNG)
[02:23:10] <cradek> I wish I understood the difference between tcl/ tcl/bin and tcl/scripts
[02:25:50] <jepler> yeah
[02:26:11] <cradek> I have a feeling ray wants some of these on the tkemc menus, but I have no idea which ones
[02:26:49] <cradek> I think I'm about ready to upload this release
[02:27:12] <CIA-8> 03jepler 07HEAD * 10axis/scripts/axis.py:
[02:27:12] <CIA-8> make redraw actually be a method of the opengl widget, modify calling sites accordingly
[02:27:12] <CIA-8> remove several commented-out debugging statements
[02:28:00] <cradek> for all of flo-h's work in tkemc, only axis seems to do something when you define LANGUAGE
[02:28:25] <fenn> tkemc wants LANG
[02:28:34] <fenn> er tcl does
[02:28:36] <cradek> that doesn't do anything either
[02:29:20] <fenn> it used to
[02:29:36] <cradek> probably someone unwittingly broke it for installed
[02:30:34] <fenn> yes it is broken
[02:38:22] <fenn> is it just me or is this amazingly overpriced? http://search.ebay.com/9709025879
[02:58:13] <A-L-P-H-A> how freak'n hard would it be if you could build just something like that? couple of encoders, some math.
[02:59:03] <cradek> yes, looks fairly simple
[03:00:04] <A-L-P-H-A> cradek... wanna machine them, I'll sell 'em? :)
[03:00:52] <A-L-P-H-A> like, get some 4K line rotary encoders for each elbow/pivot point.
[03:00:55] <fenn> alpha you need a lathe
[03:01:06] <A-L-P-H-A> I have a lathe.
[03:01:12] <A-L-P-H-A> I have a mill.
[03:01:16] <A-L-P-H-A> i have htem both CNCd.
[03:01:23] <A-L-P-H-A> I just haen't turned htem on in over 8 months.
[03:02:09] <A-L-P-H-A> It's jsut accuracy of 0.009"?
[03:02:12] <A-L-P-H-A> zeesh.
[03:02:24] <fenn> god damn brlcad and opencascade just absolutely have to have a single file for like every function
[03:02:44] <A-L-P-H-A> fenn, that's actually one methodology of coding.
[03:02:53] <A-L-P-H-A> makes it a pain in the ass to find stuff if you don't use something like grep
[03:03:06] <A-L-P-H-A> but I think you know that.
[03:03:20] <fenn> i'm trying to clean out my disk and sitting here holding down the page down button
[03:03:41] <cradek> use tags
[03:04:10] <fenn> tags?
[03:05:12] <A-L-P-H-A> TAGS.
[03:05:23] <A-L-P-H-A> it's like adding meta data.
[03:05:32] <A-L-P-H-A> or use SVN...
[03:06:26] <fenn> could you explain a little more?
[03:06:49] <A-L-P-H-A> working example
[03:06:53] <A-L-P-H-A> http://del.icio.us
[03:06:54] <fenn> i'm not working on brlcad or opencascade i'm just throwing out crap
[03:06:59] <A-L-P-H-A> http://del.icio.us/alpha1125 is me.
[03:07:03] <A-L-P-H-A> oh.
[03:07:09] <cradek> uh no
[03:07:14] <A-L-P-H-A> http://del.icio.us/alpha1125 <-- example of tagging.
[03:07:30] <cradek> no no no no
[03:07:41] <cradek> ctags `find . -name *.c`
[03:07:47] <cradek> vim -t somefunction
[03:08:19] <fenn> bash: /usr/bin/ctags: Argument list too long
[03:08:27] <cradek> find . -name '*.c'|xargs ctags
[03:08:28] <fenn> oh well
[03:08:41] <cradek> find . -name '*.c'|xargs ctags -a
[03:08:55] <A-L-P-H-A> you guys are making life complicated.
[03:09:32] <fenn> forget i said anything
[03:09:33] <A-L-P-H-A> go read something fun... http://www.popularmechanics.com/science/defense/2530001.html US toys of the future.
[03:09:41] <A-L-P-H-A> fenn, what did you say? ;)
[03:09:54] <fenn> A-L-P-H-A: huh? :)
[03:10:07] <A-L-P-H-A> ugh.
[03:10:11] <A-L-P-H-A> ugh was a fun dos game. :)
[03:17:28] <fenn> some of that really makes you wonder why they arent researching mobile robotics more
[03:17:48] <fenn> i mean, how many billions does it take to make a walking robot?
[03:18:05] <Jymmm> ask honda
[03:18:57] <fenn> i mean real walking not some servo crap that barely balances on one foot
[03:18:57] <Jymmm> fenn http://world.honda.com/ASIMO/
[03:19:09] <Jymmm> no, it fully walks
[03:19:25] <fenn> it takes 2KW just to walk
[03:19:52] <Jymmm> running at 6km/h
[03:20:04] <Jymmm> http://world.honda.com/HDTV/ASIMO/New-ASIMO-run-6kmh/
[03:20:31] <fenn> i am really not impressed by asimo
[03:21:44] <fenn> or their stupid wbsite!
[03:22:42] <Jymmm> lol... you cant' watch the videos on it can you
[03:23:14] <Jymmm> install a flash player
[03:24:10] <fenn> i have flash, and it wont let me even download the movie file
[03:26:00] <Jymmm> http://world.honda.com/HDTV/ASIMO/New-ASIMO-turning/hdtvplayerW8.swf
[03:26:43] <cradek> it's a black rectangle with a progress bar
[03:27:16] <Jymmm> not here it isn't... it's the video
[03:27:30] <Jymmm> you need version 7 or above
[03:27:42] <Jymmm> err version 8 or above
[03:27:48] <fenn> i just installed version 7 and.. what version 8?
[03:27:51] <cradek> * cradek shrugs
[03:27:57] <fenn> thats bullshit
[03:28:17] <fenn> i'm not playing the upgrade game
[03:28:46] <Jymmm> 8 has been out for about a year
[03:29:47] <fenn> apparently there's no version for linux
[03:30:02] <Jymmm> ah, bummer
[08:24:27] <Bo^Dick> still struggling with the voltage divider and the and-gate
[13:00:58] <Bo^Dick> ok i need a hand here guys. there a store that seels old dot matrix printers and i would like to know of you know what brands might have the highest probability to involve a stepper motor controller circuit such as L297/8? thanks in advance! Digital LA75 Companion Printer | NEC Pinwriter P20 | HP Deskjet 670C | HP Deskjet Plus | HP Deskjet 500C | Microtek Scanmaker E3
[13:18:34] <fenn> Bo^Dick: did you ever figure out why the diodes were so big on the pminmo board?
[13:22:36] <Bo^Dick> no
[13:44:39] <SkunkWorks> logger_aj: bookmark
[13:44:39] <SkunkWorks> See http://solaris.cs.utt.ro/irc/irc.freenode.net:6667/emc/2006-04-10#T13-44-39
[14:05:45] <SkunkWorks> websys: is if finally warming up on your side of the state?
[16:06:52] <CIA-8> 03alex_joni * 10emc2/src/configure: Code at sourceforge should be obsolete
[16:18:30] <bill2or3> * bill2or3 wakes up.
[16:22:58] <fenn> anyone know if i can use a wall wart to supply the extra oomph to drive the high side of an all n-channel h-bridge?
[16:23:33] <fenn> instead of building some funky voltage doubler
[16:34:25] <jepler> fenn: it seems like that could work, as long as the voltage is high enough. If I understand correctly, only tiny amounts of current are used.
[16:35:14] <jepler> (I've never built an h-bridge though)
[16:36:24] <giacus_afk> wooow
[16:36:28] <giacus_afk> http://www.unita.it/index.asp?sezione_cod=HP
[16:36:33] <giacus_afk> giacus_afk is now known as giacus
[16:36:43] <jepler> what I don't understand is what advantage using all n-channel is
[16:37:25] <jepler> is it because "Low RDS(on) P channel MOSFETs are more difficult to find than N channel." ?
[16:38:08] <SkunkWorks> when I was goofing around - n-channels where cheaper. but that was 10 years ago.
[16:41:50] <jepler> looking at the mouser catalog, there seem to be a lot more part numbers for n-channel than p-channel
[16:43:31] <alex_joni> jepler: cheaper usually
[16:43:39] <SkunkWorks> jmk turned me on to these chips also http://www.irf.com/product-info/datasheets/data/ir2010.pdf
[16:43:45] <alex_joni> SkunkWorks: eeeek
[16:43:48] <alex_joni> * alex_joni hates those
[16:43:56] <SkunkWorks> why is that?
[16:44:07] <SkunkWorks> you can use all n-channel
[16:44:09] <alex_joni> dunno, maybe because I fscked up a bag full?
[16:44:23] <SkunkWorks> I never have that problem ;)
[16:44:24] <alex_joni> I had about 20 IR2111, and didn't get any to work
[16:45:47] <SkunkWorks> free wheeling diodes are you friend?
[16:46:01] <SkunkWorks> ;)
[16:55:19] <SkunkWorks> 2111 is pretty cool
[16:55:23] <SkunkWorks> should just work
[16:55:45] <SkunkWorks> what kinda current where you playing with?
[17:08:55] <bill2or3> Zzzzz
[17:10:28] <SkunkWorks> what do you expect for a monday? :)
[17:16:53] <alex_joni> SkunkWorks: was playing with about 10 Amps, 24V
[17:17:00] <alex_joni> but for testing something like <1A
[17:17:09] <alex_joni> and they blew up at <1A
[17:17:23] <alex_joni> I know they should have just WORKED, but they didn't :(
[17:32:07] <SkunkWorks> alex_joni - I have the datasheet on them but have been having problems finding the application notes. How the heck do you find them on ir's site.
[17:32:38] <alex_joni> SkunkWorks: I can't really remember.. the whole chapter is blocked out in my memory :D
[17:32:49] <SkunkWorks> :)
[17:32:50] <alex_joni> this was a few years ago.. (about 3 or 4)
[17:33:49] <bill2or3> my mill is sort of starting to take shape, a little: http://photos.xmission.com/bill/v/machining/IMG_0193.JPG.html
[17:33:53] <bill2or3> please ignore the ugly temporary brackets.
[17:34:37] <SkunkWorks> is that rack mount pannel - u channel?
[17:34:47] <bill2or3> yes.
[17:34:49] <SkunkWorks> cool
[17:35:13] <SkunkWorks> makes mounting things easy to say the least
[17:35:14] <bill2or3> http://photos.xmission.com/bill/v/machining/IMG_0192.JPG.html
[17:35:32] <bill2or3> got the rack for $20 at a local freight-damage-surplus place.
[17:37:40] <SkunkWorks> nice.
[17:39:18] <bill2or3> I got some 8-tpi screws, what is the "usuall" tpi for the X-Y screws?
[17:44:43] <SkunkWorks> there is no usual
[17:45:28] <SkunkWorks> http://www.electronicsam.com/images/KandT/zaxis.JPG
[17:47:31] <bill2or3> guh
[17:47:39] <bill2or3> must be heavy. :-)
[17:48:00] <SkunkWorks> It isn't pretty but works pretty well. ;)
[18:31:01] <Imperator_> http://www.anderswallin.net/2006/04/the-new-deck-takes-shape/
[18:36:35] <bill2or3> neat
[18:37:56] <ValarQ> whats that emc2 interface?
[18:38:15] <jepler> ValarQ: in the anderswallin.net screenshot? It's "mini"
[18:38:29] <SkunkWorks> looks like what comes with the bdi
[18:38:33] <SkunkWorks> ah mini
[18:38:56] <ValarQ> hmm, never tried that...
[18:41:58] <Imperator_> ask rayh, he is a mini enthusiast :-)
[18:42:34] <ValarQ> i wish there was a curses interface...
[18:42:44] <alex_joni> ValarQ: there is one afaik
[18:42:49] <ValarQ> there is!?!
[18:42:59] <alex_joni> a non-X interface
[18:43:06] <alex_joni> not sure it's curses or not
[18:43:22] <cradek> it's curses
[18:43:26] <alex_joni> it's in emc1
[18:43:35] <alex_joni> maybe we should include it in emc2 too
[18:43:39] <ValarQ> maybe it can be ported to emc2?
[18:43:45] <alex_joni> ValarQ: trivial
[18:43:57] <cradek> probably needs only minor tweaks
[19:01:24] <CIA-8> 03alex_joni 07HEAD * 10emc2/src/ (configure.in configure): added a default place for installing tcls's *.msgs
[19:02:38] <CIA-8> 03alex_joni 07HEAD * 10emc2/scripts/emc.in: export EMC2_LANG_DIR for tcl apps
[19:04:22] <CIA-8> 03alex_joni 07HEAD * 10emc2/tcl/ (mini.tcl tkemc.tcl): tcl apps use EMC2_LANG_DIR to find *.msg's
[19:56:41] <K4ts> hello
[20:06:07] <alex_joni> anyone wants free energy? http://freeenergynews.com/Directory/Methernitha/Thestatica/index.html
[20:08:35] <jepler> umm I'm a bit skeptical of any device whose workings are described in these terms: "The two conterrotating discs generate an electrostatic charge. One disc represents the earth, the other the cloud. Using grid electrodes the charges are bound. After that they are collected by non-contacting so-called antenna keys and then sorted."
[20:08:47] <jepler> You don't get useful energy because you create a device whose parts represent things
[20:09:10] <alex_joni> lol
[20:09:18] <bill2or3> not even if I label them really clearly?
[20:09:28] <alex_joni> http://website.lineone.net/~aarekhu/index.html
[20:09:29] <bill2or3> sounds like a wimshurst machine.
[20:09:35] <alex_joni> better description
[20:09:49] <bill2or3> looks a bit like one too.
[20:10:08] <jepler> OK, I've decided that my mouse represents the earth, and my LCD represents the sky.
[20:10:16] <jepler> * jepler hooks up a multimeter
[20:10:29] <jepler> short circuit current: 0A. Open circuit voltage: 0V
[20:10:30] <jepler> heck
[20:11:21] <cradek> maybe you didn't sort your charge antenna keys right
[20:11:29] <alex_joni> try another point of the LCD
[20:11:38] <alex_joni> maybe you'll get mains :)
[20:11:45] <cradek> try a monitor, they have more electrostaticons
[20:12:01] <alex_joni> I have plenty icons on my LCD thank you
[20:20:58] <jepler> it seems unlikely that there's "free" energy of over 4kW/m3 that some natural organism wouldn't have figured out how to use (like they've figured out how to use the sun, or heat from deep-sea volcanic ducts, or by eating each other).
[20:21:34] <bill2or3> or any free energy, at all.
[20:21:35] <alex_joni> I like the last one
[20:22:02] <jepler> you like eating?
[20:22:12] <alex_joni> each other
[20:22:30] <alex_joni> jepler: yes, don't you?
[20:22:42] <alex_joni> eating is one of the pleasures in life..
[20:23:21] <jepler> let me know when you've given the chocolate-covered pork chop a chance
[20:23:37] <alex_joni> I'm not eating any meat this week
[20:24:02] <jepler> maybe next week
[20:24:04] <alex_joni> imagine that.. (that's not usual for me)
[20:24:35] <alex_joni> not likely :)
[20:25:16] <alex_joni> although I like sweet food (like steak with plums, or fruit chutney)
[20:30:39] <CIA-8> 03alex_joni 07HEAD * 10emc2/src/Makefile: compile and install src/po/*.po files to the proper location. this can be extended to work for RIP lateron
[20:48:48] <K4ts> sigh italia crak! berlusconi winner
[20:49:59] <jepler> too bad
[20:50:53] <alex_joni> jepler: why?
[20:51:04] <alex_joni> every country has the leader it deserves
[20:51:22] <alex_joni> it's usually not the right one..
[20:52:33] <jepler> I don't deserve the leader I have right now, thank you very much
[20:52:51] <alex_joni> jepler: it's not your fault..
[20:52:53] <jepler> that's the problem with democracy
[20:53:00] <jepler> I got the leader somebody else deserved
[20:53:12] <alex_joni> somebody else=majority
[20:55:44] <cradek> there's little reason to believe the majority wanted this guy, with our recent move to electronic voting.
[20:56:13] <cradek> secret, closed-source, electronic voting
[20:57:04] <ValarQ> * ValarQ points to the south and laughs
[20:57:08] <alex_joni> * alex_joni nominates cradek o design a new electronic voting system
[20:57:20] <alex_joni> s/ o / to /
[20:57:33] <jepler> 4 words: voter-verified paper trail
[20:57:40] <ValarQ> alex_joni: btw, i didn't find the curses fe
[20:57:47] <alex_joni> ValarQ: hang on
