[05:48:43] <toast> wow
[05:50:12] <SkinnyPuppy34> busy isn't it
[06:16:48] <Jymmm> never is at this time.
[06:17:03] <alex_joni> morning
[06:25:07] <Jymmm> morning alex
[07:26:02] <alex_joni> http://www.alibre.com/xpress/forum/files/kirksteabreak_667.jpg lol
[07:54:06] <anonimasu> alex_joni: wtf..
[08:13:19] <alex_joni> heh
[09:20:53] <alex_joni> anonimasu: the more I use alibre, the more I like it :)
[09:23:25] <alex_joni> if I could only redefine the way it pans/rotates
[09:25:41] <Rabbitbu1ny> Rabbitbu1ny is now known as Rabbitbunny
[09:43:42] <anonimasu> alex_joni: if only the snap would work..
[09:43:54] <anonimasu> and if they would export sketches when doing 3d stuff
[12:13:05] <Guest432> Guest432 is now known as java_client

[13:09:31] <skunkworks> The_Ball: how is the mill coming?
[13:11:03] <The_Ball> skunkworks, hey, how are you? not so well, very busy with work, just bought this: http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=120169721743 for a backup solution im making
[13:11:48] <skunkworks> Nice.
[13:11:55] <skunkworks> no more tape swapping ;)
[13:12:11] <The_Ball> hehe, nope
[13:12:47] <The_Ball> wouldn't mind it for myself actually, would be nice for archiving
[13:13:17] <The_Ball> have a 8x320gb raid5, but that is noisy and hot
[13:13:41] <skunkworks> our biggest server here is only .5TB
[13:13:53] <skunkworks> but it is on the full side.
[13:14:44] <The_Ball> the company i work for sell storage solutions, i will be making a linux based backup host for them
[13:15:31] <The_Ball> did you catch this link on the emc mailing list? http://www.compumotor.com/catalog_eng_ref.htm
[13:15:38] <The_Ball> some nice stuff there
[13:16:18] <skunkworks> looks interesting.
[13:37:29] <cradek_> cradek_ is now known as cradek
[14:01:57] <martin_lundstrom> Hello people
[14:03:24] <Dallur> hey martin
[14:03:29] <Dallur> long time no see
[14:03:47] <Dallur> I still have your domain ready for you, martinlundstrom.com
[14:04:52] <Dallur> wait it was mlundstrom.com :)
[14:13:05] <cradek> hi guys
[14:13:18] <cradek> does anyone have a lead on big transfomers?
[14:13:45] <cradek> I'm looking for 4kva, 220v single phase primary, 72v secondary
[14:26:55] <rayh> I use 240/480 to 120/140 for something like this. By connecting 240 to the 480 taps I can get ~60 AC out on the 120 tap.
[14:27:19] <JymmmEMC> cradek: Do you mind having it made?
[14:27:26] <SWPadnos> but you need a transformer with double the kva rating
[14:27:39] <SWPadnos> the current limits on the primary wires will be the limiting factor
[14:27:48] <rayh> Yep.
[14:27:49] <SWPadnos> err - on the secondsry wires
[14:27:52] <SWPadnos> ary
[14:28:02] <SWPadnos> <-- needs more coffee
[14:28:11] <rayh> me to
[14:28:34] <SWPadnos> +o ;)
[14:29:17] <JymmmEMC> cradek: If you don't mind having it made, then Yes, I do have a place for you.
[14:29:21] <cradek> JymmmEMC: not if the price is halfway sane
[14:29:38] <JymmmEMC> cradek: no, it's realistic and can be qty 1
[14:29:50] <JymmmEMC> cradek: http://www.mcitransformer.com/
[14:29:54] <cradek> rayh: thanks, I'll keep that idea in mind (I bet 8kva would be a huge transformer!)
[14:30:17] <JymmmEMC> cradek: they will help in the design phase too, very down home
[14:32:35] <JymmmEMC> SWPadnos: you said once that you used ubuntu server, why ubuntu as opposed to debian?
[14:32:44] <SWPadnos> because
[14:33:06] <JymmmEMC> keep going
[14:33:10] <SWPadnos> that was all
[14:33:12] <SWPadnos> ;)
[14:33:26] <JymmmEMC> but why damnit!
[14:33:40] <SWPadnos> actually, I have Ubuntu on several workstations, and I figured it might save some effort to have them based on the same distro
[14:33:56] <SWPadnos> I can set up a repository mirror here, for instance
[14:34:02] <SWPadnos> and I only need one
[14:34:08] <cradek> hmm, they have toroid up to 10kva
[14:34:23] <cradek> it's so simple (one primary, one secondary) I wonder if that would be the way to do it
[14:34:21] <JymmmEMC> SWPadnos: anything other than workstation support (so to speak)?
[14:34:29] <SWPadnos> ?
[14:34:40] <SWPadnos> <-- needs more coffee
[14:34:48] <JymmmEMC> cradek: They dont charge extra for custom design work.
[14:35:56] <JymmmEMC> cradek: I was having made a 4 tap secondary and very reasonable if I could wait till the end of their current workorders were complete, apx 10 days or so
[14:36:48] <cradek> thanks, I will definitely call them.
[14:37:51] <JymmmEMC> cradek: Now, if you needed special certifications... UL, medical, etc of course the custom would go up.
[14:38:09] <JymmmEMC> cradek: Now, if you needed special certifications... UL, medical, etc of course the price would go up.
[14:38:54] <JymmmEMC> http://www.mcitransformer.com/i_notes.html
[14:59:13] <JymmmEMC> OMG!!! Ubunto 7.10 ---> While previous Ubuntu releases only supported read access to Windows (NTFS) partitions, Gutsy Gibbon now fully supports reading and writing to them, by integrating the NTFS-3g project. This significantly eases file and document sharing with Windows.
[15:07:04] <skunkworks> Nice
[15:10:05] <skunkworks> gutsy does have some issues http://www.electronicsam.com/images/KandT/GLXGEARS.png
[15:12:37] <SWPadnos> it doesn't have those issues on my laptop
[15:13:02] <skunkworks> I was told to disable compiz - as it is very buggy
[15:13:11] <skunkworks> I have not tried it yet.
[15:13:29] <skunkworks> (the desktop effects if I understand it right)
[15:13:30] <SWPadnos> I didn't disable it, and I can run glxgears without those issues
[15:14:01] <skunkworks> really? I tried it on 2 different computers with the same issues.
[15:14:01] <SWPadnos> I did have an "interesting" effect one time though - a jelly-window kept being jelly-like after I had released it :)
[15:14:14] <SWPadnos> both ATI video though, right?
[15:14:14] <skunkworks> was there updates within the last few days?
[15:14:25] <skunkworks> no - one was intel - one was ati
[15:14:29] <SWPadnos> this is from a week ago - the beta (not even the RC)
[15:14:30] <SWPadnos> ok
[15:14:39] <SWPadnos> mine is nvidia restricted
[15:14:51] <skunkworks> hmmm
[15:15:25] <SWPadnos> also, I don't know that turning desktop effects off actually disables compiz
[15:35:43] <skunkworks> SWPadnos: looks like setting 'visual effects' to none fixes it.
[15:35:48] <SWPadnos> cool
[15:36:05] <SWPadnos> I did have a problem where I couldn't set visual effects to "custom"
[15:36:25] <SWPadnos> or at least the setting didn't take when I checked that option
[15:38:57] <skunkworks> this is the visual effect tab of the appearence control panel
[15:39:27] <SWPadnos> 3 options, right? "none", "default", "custom" or similar?
[15:39:53] <skunkworks> it has 3 options none, normal and extra
[15:40:04] <SWPadnos> hmmm. maybe I should update ;)
[15:41:10] <skunkworks> it defaults to normal on a fresh install
[15:41:31] <SWPadnos> right. that's close to what I'm trying to remember
[15:41:42] <skunkworks> heh
[15:41:52] <skunkworks> too much lds in collage?
[15:42:02] <SWPadnos> no, I'm not religious
[15:42:24] <skunkworks> (it was a quote from one of the startrek movies)
[15:42:35] <SWPadnos> Star Trek 4, I think
[15:42:47] <skunkworks> where they go back in time - I think so
[15:42:53] <skunkworks> shave the wales
[15:42:56] <SWPadnos> yep
[15:42:56] <skunkworks> whales
[15:43:15] <SWPadnos> and Spock tries to fit in by saying "the hell" every other word
[15:43:15] <skunkworks> (Dilber quote)
[15:43:24] <skunkworks> yah
[15:43:43] <skunkworks> skotty tries to talk to a mac
[15:43:47] <skunkworks> scotty
[15:44:17] <SWPadnos> yep. one of the good ones (the even numbers)
[15:47:35] <skunkworks> I actally liked the next generation one where they go back in time and see the first warp drive built/flown
[15:48:29] <SWPadnos> 8, I think
[15:48:31] <SWPadnos> then 9 was eh
[15:48:41] <SWPadnos> and 10 was pretty good (liek a long episode, but still good)
[15:48:59] <SWPadnos> the one with the Romulan Picard clone
[15:50:01] <skunkworks> ah - I don't like unhappy endings though... (data getting blown up) I like disney endings.
[15:50:10] <skunkworks> but it was a good movie
[15:50:38] <SWPadnos> heh
[15:50:40] <SWPadnos> then go watch bambi
[15:50:49] <skunkworks> heh
[15:50:50] <SWPadnos> oh wait, there's death in that one also (or so I hear)
[15:51:34] <skunkworks> I don't know if I have seen that one.. But yes I think the mother dies.
[15:51:48] <skunkworks> hence why I have not seen it..
[15:51:50] <skunkworks> ;)
[15:53:18] <SWPadnos> hmmm. now what was that stupid movie?
[15:54:02] <SWPadnos> I used to work in a theater, so I got (had) to see a lot of bad movies (I was the guy who spooled the reels onto the platter when new movies came in)
[15:54:58] <SWPadnos> there were a bunch of stinkers, but in one of them, there's some love triangle, and at the end, the two guys get into a shooting match and - you guessed it - they manage to kill each other
[15:55:14] <SWPadnos> so there's the sad lady, with two dead boyfriends. boo hoo
[15:55:23] <SWPadnos> fade to black, credits roll
[15:56:03] <skunkworks> yeck
[15:56:35] <skunkworks> cradek: this plus a 220/110 transformer http://cgi.ebay.com/JEFFERSON-BUCKBOOST-TRANSFORMER-216-1271-120-240-16-32_W0QQitemZ200163328960QQihZ010QQcategoryZ42881QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
[15:56:45] <skunkworks> maybe
[15:56:51] <SWPadnos> it was so bad and predictable that about 1/2 hour before the end, I said to my friend
[15:57:12] <SWPadnos> "watch, they'll end up killing each other, and she'll be left with no-one"
[15:57:23] <SWPadnos> he almost choked on his soda when it happened
[15:57:58] <skunkworks> 60v+ the boost on the primary..
[15:58:35] <skunkworks> my father is good at predicting movies endings.
[15:59:12] <SWPadnos> movies in the last 10-20 years have been very bad regarding predictability
[15:59:40] <SWPadnos> and if they say it's "wildly funny and unpredictable", you just change your predictions to the opposite, and then you're still right
[15:59:47] <skunkworks> I would have to say - 6th sence took me by supprise.
[15:59:52] <SWPadnos> except in rare cases
[15:59:56] <SWPadnos> yes, that was a good one
[16:00:11] <skunkworks> fight club was good also
[16:00:30] <SWPadnos> if you haven't seen it, I highly recommend "12 Monkeys" (though there is death in that one, so be prepared ;) )
[16:00:50] <skunkworks> heh
[16:00:54] <anonimasu> ge
[16:00:56] <anonimasu> heh
[16:01:08] <SWPadnos> another one (just looking at the DVD collection here) -
[16:01:10] <skunkworks> seven was good
[16:01:24] <SWPadnos> "Instinct", with Anthony Hopkins and Cuba Gooding Jr
[16:01:34] <skunkworks> hmm not seen that one
[16:33:33] <Guest356> Guest356 is now known as skunkworks_
[16:35:36] <skunkworks_> oops - only 2kva
[16:42:54] <SWPadnos> it's pretty amazing how much compiz slows down 3D apps
[16:43:31] <SWPadnos> glxgears with desktop effects on does about 8150 FPS, with effects off it's 12550
[16:43:37] <skunkworks_> heh - but it seemed like a good idea at the time..
[16:44:04] <skunkworks_> but you don't get the problem either way?
[16:44:24] <SWPadnos> nope
[16:44:27] <skunkworks_> interesting.
[16:44:49] <SWPadnos> so both before and after updating, I didn't have the problem
[16:46:51] <skunkworks_> must be somewhat related to hardware
[17:11:20] <skunkworks_> cradek: http://cgi.ebay.com/15-KVA-Acme-general-purpose-single-phase-transformer_W0QQitemZ110178644589QQihZ001QQcategoryZ42881QQssPageNameZWDVWQQrdZ1QQcmdZViewItem#ebayphotohosting
[17:11:29] <skunkworks_> that has a lot of primary taps.
[17:13:18] <skunkworks_> but... the wrong way
[17:18:17] <skunkworks_> if I did the math right - it only gets you 61.1v
[17:18:46] <skunkworks_> with the 432 tap
[17:19:46] <skunkworks_> assuming 220v
[17:20:56] <skunkworks_> have you measured your 220v? is it 220?
[18:34:03] <CIA-8> 03alex_joni 07TRUNK * 10emc2/docs/man/man1/io.1: alias for iocontrol.1
[19:02:37] <CIA-8> 03alex_joni 07TRUNK * 10emc2/configs/puma/puma.ini: fix some values
[19:02:59] <CIA-8> 03alex_joni 07TRUNK * 10emc2/configs/puma/puma_postgui.hal: make pyvcp stuff work again
[19:28:40] <SkinnyPuppy34> Question about paraports, from the users manual " 1 HAL cannot automatically determine if the “x” mode bidirectional pins are actually open collectors (OC). If they are not,they cannot be used as inputs, and attempting to drive them LOW from an external source can damage the hardware." Is this applicable to newer pc's or a problem on older hardware?
[19:31:33] <cradek> skunkworks_: it's right at 240 today
[19:32:16] <cradek> 170 lb!!!
[19:32:46] <alex_joni> good night all
[19:33:01] <cradek> goodnight alex
[19:33:35] <skunkworks_> cradek: that would be 66.6v then..
[19:34:09] <cradek> = 93 dc
[19:34:13] <skunkworks_> 432/120 = 3.6:1 240/3.6=66.67v
[19:34:14] <cradek> but 170 lb!!
[19:34:34] <skunkworks_> it is the range of kva you will need :)
[19:34:38] <cradek> I bet the one in there weighs about 40
[19:35:31] <cradek> steves_logging had some toroids at fest that were probably for geckos (so maybe they're about 100v) - I should ask him what he has
[19:35:44] <skunkworks_> I don't know if you want to take that bet..
[19:36:01] <skunkworks_> ;)
[19:36:54] <cradek> ok maybe not... but I think 3 phase can be a LOT less iron than 1 phase
[19:37:03] <skunkworks_> probably
[19:37:05] <anonimasu> I use a welder for transorming..
[19:37:33] <cradek> "I guess wishing is not a valid method for repairing machinery." hahaha
[19:38:05] <skunkworks_> cradek: that and a buck/boost transformer... ;)
[19:39:22] <cradek> I'm hoping for something that will fit where the original is - so I would prefer to not have two of them
[19:39:36] <skunkworks_> picky picky picky.. ;)
[19:43:26] <skunkworks_> If you have someone make you a toroidal - wouldn't it be better to do the 144vct?
[19:43:38] <skunkworks_> to rectify and smooth out.
[19:45:10] <SWPadnos> I think the waveform is the same, but you only get half the power when you rectify to a center-tap
[19:45:28] <cradek> right, what SWP says, the transformer has to be twice as big
[19:45:31] <SWPadnos> also, that may only be good for +/- supplies
[19:45:38] <cradek> and I think it only saves you two diodes
[19:45:41] <skunkworks_> ah
[19:45:42] <cradek> (no other benefit)
[19:46:01] <cradek> except if you're using an 80 tube to regulate it, then it really helps :-)
[19:46:08] <SWPadnos> it is a benefit for 3-phase, but not for single phase
[19:46:09] <skunkworks_> heh
[19:46:24] <skunkworks_> that is what I was trying to extrapilate..
[19:46:29] <skunkworks_> extrapilate?
[19:46:49] <SWPadnos> s/i/o/
[19:47:24] <SWPadnos> yay! I have the DACs working now!
[19:47:55] <SWPadnos> strangely, at ~167 KHz - very close to the ADC scan rate of 165 KHz
[19:49:25] <skunkworks_> any major revisions to your circuit?
[19:50:20] <SWPadnos> nope, this has all been FPGA issues
[19:50:31] <skunkworks_> nice
[19:50:37] <skunkworks_> I think ;0
[19:50:58] <SWPadnos> I had copy/paste errors on 12 of the 36 tantalum caps, so they had to be reversed. there were two ICs that had to be rotated 180 degrees (same stupid VSS versus VDD thing)
[19:51:00] <SWPadnos> heh
[19:51:38] <SWPadnos> last night I found out that for the last 3 days, I've been chasing a problem that was caused by the Xilinx tools not doing incremental compiles correctly
[19:53:32] <skunkworks_> yikes
[19:58:03] <SWPadnos> yes
[19:58:17] <SWPadnos> especially when I've been up until 3AM to 7AM chasing the problem :(
[19:59:55] <SkinnyPuppy34> Gecko common connects to the shield ground on breakout board correct?
[20:02:41] <SkinnyPuppy34> Sorry for the noob questions just making sure I don't let the smoke out.
[20:03:29] <SWPadnos> there are multiple commons on a gecko, which one are you talking about?
[20:03:50] <SWPadnos> also, do you have the step/dir inputs set for common +5V or common ground? (if that's available on the 203V)
[20:04:08] <SkinnyPuppy34> g203 common aside the step/dir
[20:04:52] <SkinnyPuppy34> The pinksheet they came with only says "Common connect terminal to controller ground output."
[20:05:39] <SWPadnos> you should have a ground wire, which may be connected on the BOB to the shield, but you shouldn't be using the shield as a current-carrying conductor
[20:07:14] <CIA-8> 03fenn 07TRUNK * 10emc2/lib/python/vismach.py: the global keyword does not define the variable
[20:08:18] <CIA-8> 03fenn 07TRUNK * 10emc2/src/emc/usr_intf/axis/scripts/hexagui.py: joint coordinates should line up with kinematics now
[20:10:43] <fenn> email is now officially deprecated, by authority of fenn
[20:11:06] <SWPadnos> fenn is now officially deprecated, by authority of SWPadnos
[20:11:18] <fenn> i'm already retired, sucker
[20:11:29] <SkinnyPuppy34> SWPadnos: A groundwire back to computer chassis ground is what I would need yes?
[20:11:31] <SWPadnos> then you're depreciated instead!
[20:11:43] <fenn> * fenn wonders what that's supposed to mean
[20:12:00] <SWPadnos> SkinnyPuppy34, the ground goes to whatever is driving the step/dir bits
[20:12:38] <SWPadnos> unfortunately, I don't have time to think about it much at the moment. hopefully ssomeone else can jump in to help you out.
[20:17:51] <SkinnyPuppy34> Thats cool, I think i got it. Just wiring the breakout board as per the standard_pinout.hal xyza. Just cautious being my first system
[20:57:13] <anonimasu> did anyone see awallin around
[21:00:28] <lerneaen_hydra> anonimasu; know of a place in sweden that's got cheap V-belt wheels and belts?
[21:00:37] <anonimasu> jula..
[21:00:49] <lerneaen_hydra> oh, have they got them? sweet
[21:01:03] <lerneaen_hydra> btw, do you know anything about upper RPM limits for v-belts?
[21:01:13] <lerneaen_hydra> and/or perifrial speed limits
[21:01:36] <anonimasu> no
[21:01:53] <anonimasu> pretty fast I guess..
[21:02:04] <lerneaen_hydra> ok, 10krpm?
[21:02:36] <anonimasu> im not sure
[21:02:45] <anonimasu> http://www.jula.se/e-Sales/esa/default.jsp
[21:02:58] <anonimasu> Kilremsskivor
[21:03:02] <anonimasu> and
[21:03:06] <lerneaen_hydra> yeah, found both
[21:03:08] <anonimasu> AV-remmar
[21:03:09] <anonimasu> :)
[21:03:09] <lerneaen_hydra> nice and cheap
[21:03:15] <anonimasu> I'd use toothed belts..
[21:03:21] <anonimasu> as you can get specs for them ;)
[21:03:26] <anonimasu> but they are much more expensive
[21:03:41] <lerneaen_hydra> yeah, for my purposes lifespan doesn't really matter
[21:04:38] <anonimasu> ok
[21:06:22] <lerneaen_hydra> thanks for the tip :)
[21:06:45] <anonimasu> np
[21:41:34] <Ziegler> lerman
[21:41:49] <Ziegler> I saw your post on HAD
[21:42:21] <Ziegler> opps... lernean_hydra
[21:42:28] <Ziegler> but he just left
[22:03:44] <LawrenceG> JymmmEMC: ding dong....
[22:44:09] <dmess> hi all
[23:39:18] <JymmmEMC> LawrenceG:
