#emc | Logs for 2005-07-02

[00:02:18] <alex_joni> great stuff
[00:02:25] <alex_joni> expensive?
[00:04:14] <Jymmm> dont know, the eond of the video says plans available, but when you check the site no plans are available but he's making kits
[00:04:26] <Jymmm> and they aren't available yet
[00:04:45] <Jymmm> http://michaelconnally.com/
[00:05:44] <Jymmm> *****
[00:05:59] <alex_joni> :(
[00:08:37] <fenn> crikey i gotta make a life-sized version
[00:08:53] <alex_joni> fenn: whatcha talking about?
[00:09:04] <fenn> the air boat thingy
[00:09:10] <alex_joni> ahh
[00:09:24] <alex_joni> * alex_joni is tired
[00:11:47] <Jymmm> fenn : OKEY! You ride in it, I'll fly it from the RC =)
[00:14:33] <Jymmm> fenn : JUST HANG ON FOR DEAR LIFE
[00:14:47] <Jymmm> I won't kill ya, but you just might wish you were dead =)
[00:15:03] <Jymmm> or the best damn roller coaster ride you've ever had!
[00:19:02] <alex_joni> * alex_joni goes to bed
[00:19:04] <alex_joni> night guys
[00:20:44] <Jymmm> night alex_joni
[01:15:24] <Jymmm> ya know, it's a real bitch grating frozen cheese! lol
[02:27:29] <bpmw_> Hey Jymmm, is Alex going to be back?
[02:30:33] <bpmw_> Is anybody using Quadrature instead of step/direction?
[03:43:50] <LawrenceG> quad is great ! about 4x the speed of the step/dir driver because there are no problems with setup and hold times... you can move each time through the emcmot driver...
[03:44:26] <LawrenceG> I am using quad drive with my shoptask and tmg driver system... let me know if you need example configs.
[03:45:20] <Jymmm> hey LawrenceG
[03:46:07] <LawrenceG> hey jymmm... just back back from a Canada Party.... some good scotch whiskey was enjoyed by all!
[03:46:21] <Jymmm> LawrenceG Ah... Happy Canada Day!
[03:46:44] <LawrenceG> just in training for July 4th!
[03:46:54] <Jymmm> LOL there ya go!
[03:47:15] <Jymmm> you gonna be around for a while?
[03:47:40] <LawrenceG> should be for a few hours.... may give up and go watch tv for a while...
[03:47:40] <Jymmm> brb... smoke
[03:47:57] <LawrenceG> k
[03:52:46] <Jymmm> back
[03:53:04] <LawrenceG> Do you have skype installed?
[03:53:17] <Jymmm> no
[03:53:48] <Jymmm> trying to test yours out?
[03:53:58] <LawrenceG> too bad... works well for shooting the breeze
[03:54:03] <Jymmm> lol
[03:54:08] <Jymmm> no mic
[03:54:13] <Jymmm> connedted
[03:54:49] <LawrenceG> I am using a usb headset... very easy... doesnt mess up the normal linux sound card stuff
[03:55:20] <Jymmm> Ya know, I'm not really a USB fan too much.
[03:55:28] <LawrenceG> I had a good chat with les a few nights ago.
[03:55:45] <Jymmm> ah, very cool.
[03:55:53] <LawrenceG> I know what you mean about USB... it took over 10 years for pc support to kind of work
[03:56:41] <Jymmm> it's all the polling involved... I still have to use pure UART rs232 serial port for things
[03:56:52] <LawrenceG> the power over ethernet stuff would have worked better.... no new drivers to write
[03:57:09] <Jymmm> Even when I bought my laptop I made sure it hade a serial port
[03:57:53] <Jymmm> I remember hearing about that, never saw anything come of it.
[03:58:08] <LawrenceG> My old laptop has both serialand parallel.... very useful... I even use it to run emc on my mill sometimes... just plugs in
[03:58:40] <Jymmm> I have serial, parallel, usb, and firewire. I think I'm good to go.
[03:58:58] <Jymmm> on my laptop that is
[03:59:05] <Jymmm> even has a built in fdd =)
[03:59:25] <LawrenceG> about the pnly thing that I have seen with firewire is some of the video camera stuff
[04:00:01] <Jymmm> Thats what I use it for... I have a digital video camera. The only negative thing is the transfer is real time.
[04:00:31] <Jymmm> oh and the fact the tapes can hold like 40GB
[04:02:35] <LawrenceG> man... I made a pot of curried tomatoes for dinner .... it is HOT..... I think I need to go find the suntan lotion
[04:02:51] <Jymmm> salt baby, salt.
[04:03:12] <Jymmm> I love currie, hate tomatoes.
[04:05:27] <LawrenceG> too bad..... I think I must be half Italian... love tomatoes... mybe the other half is indian because the currie sure is good as well
[04:06:16] <LawrenceG> kind of a quiet day on irc today
[04:06:21] <Jymmm> I think it's the acidity in them I don't care for, becasue I love spaghetti, pizza, ketchup, etc.
[04:06:34] <Jymmm> It's been kinda quiet all wekk
[04:07:24] <LawrenceG> guys must be burned out after the cncfest.... sounds like they slaved in the heat...
[04:07:44] <Jymmm> and probably got back logged with stuff as well.
[04:08:30] <Jymmm> do you do 3d stuff by chance?
[04:10:07] <LawrenceG> no... not on cnc.... used to do a lot or 3d scanning of logs and boards in the sawmill industry.... still trying to figure out how to move some of that to cnc applications
[04:11:07] <LawrenceG> I tried doing my house plans in 3d acad..... never could get the roof on top of the walls
[04:11:17] <Jymmm> lol
[04:11:32] <Jymmm> now why woudl you want the roof there silly?!
[04:12:13] <LawrenceG> it looked good to me, but the building inspector would have made me build it according to the plan!
[04:12:32] <Jymmm> I want to drill holes at 45 degree angle by turning the head, but someone said I would need a 4th axis instead adn that I would need a CAM that supported that.
[04:13:05] <Jymmm> it's only 3 axis, I just need to simulate the 4th
[04:14:47] <LawrenceG> if its just a few holes, you could probably do the hole cycle by hand in gcode....
[04:15:28] <Jymmm> a few hundred holes, in a grid pattern. Basically it's to make a thread spool holder.
[04:17:28] <LawrenceG> does your whole z axis tilt... like a bridgeport head or do you have to move x,y,z all together?
[04:18:33] <Jymmm> LawrenceG I'm gonna make it tilt http://k2cnc.com/Picture/KS-2525gallery/pages/Pic%20cnc%20router%2025x25%20(7).htm
[04:22:31] <LawrenceG> seems like you could layout your x,y grid of holes... then calculate an offset for the y value to compensate for the head angle.... z axis move would just have to be a little longer
[04:23:51] <Jymmm> When I ordered the machine, I had the gantry clearnace increased as well as the Z travel. Hopefully It;ll ship next week.
[04:24:11] <LawrenceG> I am assuming you will be using an endmill for drilling not a standard twist drill
[04:24:33] <Jymmm> endmill, router bit, something along those lines.
[04:24:51] <LawrenceG> looks like a nice clean design
[04:25:14] <Jymmm> more pics http://k2cnc.com/Picture/KS-2525gallery/index.htm
[04:26:07] <Jymmm> They do use roller skate bearings (ABEC7) for some things, but I just couldn't build one myself in cost or labor (out of mdf no less) for what they were offering.
[04:27:08] <Jymmm> I had bought some of the exact same bearings they are using, and even when I toss on a 20lb bar, it rolled smoother that water on glass.
[04:28:27] <Jymmm> plus they have a 15 day money make guarntee
[04:28:51] <LawrenceG> impressed.... what kind of $$
[04:29:15] <Jymmm> http://www.k2cnc.com/KS-2525_detail.asp
[04:29:29] <Jymmm> that's what I ordered + the mods
[04:33:22] <LawrenceG> the design for the linear bearings looks interesting.... I have been trying to figure out a simple system along the same lines
[04:35:40] <LawrenceG> are you familiar with the "c" channel used for mounting electrical equipment... its a heavy gauge steel form. I want to use it to enclose the drive rod (3/4 ready rod) and to run the bearing on
[04:36:17] <LawrenceG> it is quite rigid and cheap
[04:47:00] <Jymmm> the channel that hanger are connected to?
[04:47:03] <Jymmm> hangers
[04:47:36] <LawrenceG> yes... about 1/8" thick and about 2x2" with one face open
[04:48:11] <LawrenceG> just watching vides of your machine...
[04:48:42] <Jymmm> yeah, the videos aren't all that great imo
[04:54:39] <Jymmm> oh, they got more videos up there
[05:55:55] <Phydbleep> LawrenceG: That stuff is called 'Versa-Strut' around here.
[06:18:27] <Jymmm> howdy Phydbleep
[06:20:24] <Phydbleep> Hi Jymmm :)
[06:20:42] <Phydbleep> * Phydbleep has been busy fixing other peoples problems...
[06:21:13] <Jymmm> well I can hand you mine if a cargo container if you like
[06:21:17] <Jymmm> s/if/in/
[06:22:07] <Phydbleep> Does it need 3-phase power?
[06:22:44] <Jymmm> nope, mor elike 3 floors of lawyers, bankers, and one small diet soda
[06:23:42] <Phydbleep> Send that container to to the bottom of the sea. :)
[06:23:58] <Jymmm> lol
[06:24:10] <Jymmm> hey do you use 3d CAM ?
[06:24:43] <Phydbleep> What do you call 2000 lawyers on a sunken ship?
[06:25:11] <Jymmm> sharks out of water?
[06:25:44] <Phydbleep> Nope... Either "It's not enough" or "That's a good start". :)
[06:25:52] <Jymmm> lol
[06:26:31] <Phydbleep> What's the difference between a lawyer and a hooker?
[06:26:56] <Jymmm> one screwing feels good?
[06:27:07] <Phydbleep> The hooker will stop screwing you when you're dead...
[06:27:30] <Jymmm> heh
[06:28:29] <Phydbleep> Shakespeare had the right idea, but he could never find a cannon big enough to get them all in...
[06:30:40] <Jymmm> I love 'Pimp My Ride'
[14:28:32] <anonimasu> *burns a debian iso*
[17:03:48] <A-L-P-H-A> morn
[17:42:14] <alpha> how do I see how much space a given folder is taken up via the cli?
[17:42:20] <alpha> err, term
[17:42:27] <robin_sz> du -sh
[17:42:45] <robin_sz> (if you do it in the folder)
[17:42:52] <alpha> thanks
[17:43:28] <robin_sz> du --max-depth=1 -h to see how much all the tings in a dir are using
[17:46:19] <anonimasu> hm..
[17:46:34] <anonimasu> whoever that made the debian (3.1) release must be stupid.
[17:46:56] <robin_sz> why so?
[17:48:05] <anonimasu> ncurses dev isnt included, and the kernel does not ship with a driver that works with my internal card..
[17:48:45] <robin_sz> what do you mean by "isnt included"?
[17:48:48] <anonimasu> and there are no kernel sources included on the first cd on the set..
[17:49:17] <robin_sz> so you cant see stuff as it tries to boot?
[17:49:29] <anonimasu> I cant grab the kernel off the net...
[17:49:34] <anonimasu> without a network card..
[17:49:49] <robin_sz> this is during install right?
[17:49:53] <anonimasu> and I dont feel like going through make config..
[17:50:00] <anonimasu> afterwards
[17:50:17] <robin_sz> so it installed ok?
[17:50:23] <anonimasu> ofcourse..
[17:50:33] <robin_sz> so just apt-get ncurses-dev then
[17:50:41] <anonimasu> where should I get the ncurses from?
[17:51:01] <robin_sz> just use the usual apt-get ??
[17:51:12] <anonimasu> oh, they are not included on the cd.
[17:51:19] <anonimasu> and I dont have any network card working yet
[17:51:22] <anonimasu> :D
[17:51:32] <robin_sz> no network? coo . thats bad
[17:51:38] <robin_sz> but not a pronblem
[17:51:50] <anonimasu> not really a problem though
[17:51:51] <robin_sz> they probably are on the CD
[17:51:56] <anonimasu> no, they are no on the cd..
[17:51:59] <anonimasu> :)
[17:52:05] <anonimasu> it's on another cd of the set that I dont have..
[17:52:08] <anonimasu> probably
[17:52:17] <robin_sz> ahh
[17:52:22] <robin_sz> the either:
[17:52:27] <robin_sz> get a network card working
[17:52:29] <robin_sz> or ..
[17:52:29] <anonimasu> they included gnome instead of kernel sources for example..
[17:52:43] <robin_sz> d/l the ncurses-dev .deb and install it
[17:53:26] <robin_sz> I'm still unsure why yu want to re-compile the kernel though
[17:53:48] <anonimasu> to remove 99% of all modules.
[17:54:03] <anonimasu> and to get the network card working..
[17:54:04] <robin_sz> on a 2.6 kernel?
[17:54:13] <anonimasu> 2.4.27
[17:54:27] <anonimasu> going to upgrade it to 2.6 in just a moment..
[17:54:34] <robin_sz> just run 2.6 and its all modular anyway
[17:54:46] <anonimasu> * anonimasu sighs
[17:54:53] <anonimasu> I should install slackware again.
[17:55:03] <robin_sz> sounds painful
[17:55:24] <anonimasu> not really, the only problem is that the graphics card drivers comes as rpm..
[17:55:32] <anonimasu> and the rpm2tgz does not work with the packages..
[17:55:35] <robin_sz> nvidia?
[17:55:39] <anonimasu> no, ati
[17:55:50] <robin_sz> sounds unsupported
[17:56:09] <anonimasu> hm, they seem to work pretty good..
[17:56:09] <robin_sz> is there not a pseudo package for it?
[17:56:15] <anonimasu> no
[17:56:18] <anonimasu> not htat I've found..
[17:56:19] <robin_sz> sure?
[17:56:24] <anonimasu> I dont care what dist I run really
[17:56:28] <anonimasu> I could run fbsd for all I care..
[17:56:29] <robin_sz> have you asked on #debian?
[17:56:46] <anonimasu> so I can get a RTFM slapped in my face ;)
[17:57:15] <robin_sz> oh well ... thats what I'd do ... ask
[17:57:23] <anonimasu> it's not a problem..
[17:57:40] <anonimasu> I am just a bit pissed why they couldnt include the devel stuff on the first cd of the set..
[17:57:53] <anonimasu> gnome > all
[17:58:02] <robin_sz> id be suprised if they included ANY devel stuff on the first CD
[17:58:28] <robin_sz> ive never needed a set of cds anyway ...
[17:58:34] <robin_sz> always doen 'net installs
[17:58:47] <robin_sz> stick the 'net cd in
[17:58:47] <anonimasu> well, it's stupid.. being without devel stuff cripples the system..
[17:58:49] <robin_sz> hit go
[17:58:55] <anonimasu> yep..
[17:58:55] <robin_sz> come back a few hours later, all done
[17:59:20] <anonimasu> I'll just grab ncursess to the usb memory stick..
[17:59:52] <anonimasu> but well, annoying.
[18:01:26] <anonimasu> :)
[18:01:43] <anonimasu> * anonimasu lost a coke bottle somwhere
[18:02:22] <anonimasu> I can mess with this another day
[18:02:30] <anonimasu> I am going to stockholm to see black sabbath
[18:07:03] <anonimasu> the reason I need the drivers is because I want hardware accelerated X so I can play games when at lan parties with friends :)
[18:09:34] <alpha> anyone have issues installing firefox on the bdi?
[18:09:52] <alpha> seems to give me GDK warnings, and I can only run firefox via sudo ./firefox
[18:10:42] <alpha> alpha is now known as alpha_emc
[18:15:04] <alpha_emc> trying it now using the automatic method.
[18:15:50] <anonimasu> ok
[18:19:54] <alpha_emc> nope. no go.
[18:19:58] <alpha_emc> fack
[18:20:57] <A-L-P-H-A> * A-L-P-H-A slaps alpha_emc around a bit with a large trout
[18:22:27] <anonimasu> hm, I wonder where jmk is..
[18:27:17] <anonimasu> I would have loved to hav a talk about jog wheels.
[19:24:49] <robin_sz> * robin_sz istrying something difficult
[19:26:59] <robin_sz> I'm trying to buy someting called a 'lamp' ...
[19:32:25] <A-L-P-H-A> wow.
[19:32:28] <A-L-P-H-A> what's a lamp?
[19:36:12] <robin_sz> a glass thing, that takes electricity and turns it into light
[19:36:24] <robin_sz> seems to be difficult.
[19:36:37] <cradek> are you looking for a hard to find type?
[19:36:43] <robin_sz> apparently, yes
[19:37:00] <robin_sz> 48mm, 24V 20W halogen reflector
[19:39:31] <cradek> what did it come out of? is there a part number on it?
[19:40:12] <robin_sz> 41930SP ...
[19:40:15] <robin_sz> ahh found one!
[19:42:40] <anonimasu> nice
[19:45:06] <Jymmm> Howdy!
[19:47:11] <robin_sz> right, lamp ordered
[19:49:36] <Jymmm> oh wth... AMD64 mobo STILL only support MAX 2GB ram *sigh*
[20:12:05] <robin_sz> tomorow, I get to play with the 2nd CNC laser .. see if I can get the motion systems up and running
[20:12:49] <anonimasu> :)
[20:13:03] <robin_sz> big AC servos
[20:14:10] <robin_sz> might be an EMC candidate even
[20:14:18] <anonimasu> * anonimasu just had a nice discussion about self auditing systems..
[20:14:33] <anonimasu> neat!
[20:14:49] <robin_sz> the servo card will be the problem I suspect
[20:15:04] <anonimasu> yeah, the tp :/
[20:15:17] <robin_sz> I thought the to was fixed?
[20:15:24] <robin_sz> tp was fixed?
[20:15:26] <robin_sz> no?
[20:16:04] <anonimasu> no
[20:16:09] <robin_sz> oh.
[20:16:16] <anonimasu> there's a candidate I think..
[20:16:36] <anonimasu> damn, I wish I had time to learn the math
[20:16:46] <robin_sz> to be honest, without a working tp, its not viable is it?
[20:17:41] <robin_sz> this machine is much slower than my 'big' laser .. so wont need any great tp
[20:17:56] <robin_sz> just line-to-arc and line-to-line blending
[20:18:08] <robin_sz> at slowish speeds
[20:18:13] <anonimasu> define slow-ish
[20:18:21] <robin_sz> slow ... 10m/minute
[20:18:32] <robin_sz> max
[20:18:37] <anonimasu> LOL
[20:18:47] <anonimasu> * anonimasu slaps robin_sz
[20:18:52] <robin_sz> ??
[20:18:55] <robin_sz> thats slow
[20:19:07] <anonimasu> I mill at 2m/min
[20:19:18] <anonimasu> the tp will break at thoose speeds.
[20:19:26] <robin_sz> oh feck
[20:19:36] <robin_sz> well, its not an EMC candidiate then :)
[20:19:39] <robin_sz> bugger
[20:19:43] <anonimasu> yeah..
[20:19:50] <anonimasu> the tp wont support bridgeport speeds..
[20:20:06] <robin_sz> pissflaps :(
[20:20:09] <anonimasu> whatever that means.. but 10m/min is fast..
[20:20:17] <robin_sz> nah, thats slow ..
[20:20:21] <anonimasu> it's fast..
[20:20:23] <robin_sz> this is a 1977 machine
[20:20:34] <anonimasu> hobby speed wise..
[20:21:07] <robin_sz> well, sure .. but if I wanted hobby speeds, i;d use hobby software .. emc is 8supposed* to be pro software
[20:21:30] <anonimasu> * anonimasu nods
[20:21:32] <robin_sz> its currently running on a 6502 based controller ...
[20:21:39] <robin_sz> but its clunky
[20:21:50] <robin_sz> surely emc can outperform a 6502?
[20:22:59] <robin_sz> sigh .. oh well, you are sure it wont perform at 10m/minute?
[20:23:28] <anonimasu> you should have a talk with les..
[20:23:43] <anonimasu> he knows.. :)
[20:23:53] <anonimasu> I am not sure since I havent been running at thoose speeds..
[20:23:59] <robin_sz> yeah .. but i thought progress had been made?
[20:24:05] <anonimasu> my box cant crank out pulses that fast..
[20:24:10] <anonimasu> not that I know of..
[20:24:11] <anonimasu> :/
[20:24:14] <robin_sz> this is real servos,
[20:24:20] <robin_sz> no pulses needed
[20:24:26] <anonimasu> I have real servos.
[20:24:36] <anonimasu> but no real drives.. & servocard..
[20:24:44] <anonimasu> saving up until the tp is fixed..
[20:24:44] <robin_sz> geckos huh?
[20:24:58] <anonimasu> and galil servos
[20:25:01] <robin_sz> so ...
[20:25:15] <robin_sz> that leaves ..
[20:25:17] <robin_sz> Baldor
[20:25:47] <Jymmm> you think this will run emc1/2? outpost.com search for 4199563
[20:28:38] <anonimasu> I'll be off for a few days..
[20:28:39] <anonimasu> laters everyone
[20:29:59] <robin_sz> cya anonimasu
[20:52:08] <Imperator_> LawrenceG: Are you arround ?
[20:52:27] <Jymmm> only if he sits on his butt all day
[21:00:48] <robin_sz> * robin_sz ponder what to do ...
[21:01:38] <robin_sz> the options for making big ac servos do what they are told are limited :(
[21:02:14] <LawrenceG> yep...
[21:09:05] <Jymmm> LawrenceG "Imperator_ stood you up!"
[21:10:11] <Imperator_> sorry, have found the information i was searching
[21:10:16] <LawrenceG> kind of a slow day here... watching some guys build motorcycles on tvtime
[21:10:40] <Jymmm> LawrenceG L I can only watch that for so long.
[21:10:42] <Imperator_> i searched for the RS422 driver used at the breakoutboards for the mesa card
[21:10:46] <SWPadnos> "Orange County Choppers" ?
[21:10:53] <Jymmm> yeah
[21:10:57] <Imperator_> hi stephen
[21:10:59] <LawrenceG> occ it is
[21:11:01] <SWPadnos> hi Martin
[21:11:11] <SWPadnos> Fun show, if you keep the sound off :)
[21:11:12] <Imperator_> you get your card ?
[21:11:19] <SWPadnos> (the dialogue is pretty lame)
[21:11:31] <SWPadnos> I did - no documentation, just a card in a static bag
[21:11:41] <SWPadnos> Haven't had the chance to put it into a machine yet
[21:12:20] <SWPadnos> Jymmm, you may want more RAM in that computer, but it looks OK to me otherwise
[21:12:27] <Imperator_> hm, we tryed to phone to mesa yeaturday, but nobody picked up the phone
[21:12:47] <SWPadnos> there could be a problem with parallel port drive strength though - you should definitely get a breakout / buffer card
[21:13:01] <Jymmm> SWPadnos cool
[21:13:04] <SWPadnos> odd - they answered my call :)
[21:13:12] <SWPadnos> they shipped the next business day as well
[21:13:22] <Imperator_> yeaturday ?
[21:13:34] <SWPadnos> nope - a week ago
[21:13:43] <SWPadnos> What time of day did you call them?
[21:13:43] <Imperator_> hm
[21:14:06] <Imperator_> Jan tryed it
[21:14:20] <Imperator_> he is the other one working on our project
[21:14:40] <Imperator_> don't know which time he tryed it
[21:14:41] <SWPadnos> This is a holiday weekend - they may have been off work early (or not in at all)
[21:15:10] <Imperator_> ok
[21:15:20] <Jymmm> probably off work by noon.
[21:15:26] <Imperator_> is next monday is a normal day ?
[21:16:54] <SWPadnos> no - that's the holiday - Independence Day, July 4
[21:17:06] <Imperator_> ahh
[21:17:43] <Imperator_> so we have to try on tuesday
[21:21:34] <Imperator_> I'm working at the moment on some breakout boards
[21:23:09] <Imperator_> 1. 4x Counter inputs with RS422 drivers and 4x (2x Limit and 1x Ref Inputs with optocuppler)
[21:24:52] <Imperator_> 2. 4x DAC out and 2x relays 2x Input for each DAC output (for enabeling the servo amp, and reading back amp errors and so on
[21:25:26] <Imperator_> 3. digital IO card with relay outputs and optodecouppled inputs
[21:26:15] <Jymmm> SWPadnos you think that system is faster than Celeron 366? (I have no clue on AMD cpu's)
[21:27:53] <SWPadnos> I don't think AMD has sold a CPU slower than a Celery 366 for the last 5 years
[21:28:31] <SWPadnos> The Athlon 2200 will be roughly like a P4 2.2GHz - hence the 2200 rating
[21:28:48] <SWPadnos> (Sempron2200 - maybe a little slower, since it has less cache)
[21:30:02] <Jymmm> SWPadnos Ah, ok. So if I bump it up the ram, do you think the onboard video will be an issue?
[21:30:09] <Jymmm> nm that one,
[21:30:47] <Jymmm> It's $150 on sale
[21:36:05] <SWPadnos> I'm not familiar with those SIS chips - I think the video is a separate chip, but if it's in the chipset, I'd steer clear
[21:36:36] <SWPadnos> (my machine has a C&T chip on the mainboard, so it's a slightly different story, though it does use main memory for the video chip)
[21:37:44] <SWPadnos> gotta run - working with the wife in the garage :)
[21:37:50] <SWPadnos> SWPadnos is now known as SWP_Away
[21:42:37] <Jymmm> Uh oh.... DONT LET HER THROW AWAY ANYTHING!!!
[21:43:08] <Jymmm> Holy Shit.... yahoo auctions are now completely free!
[22:09:57] <bpmw_> Hi folks!
[22:16:23] <robin_sz> g'day
[22:16:39] <bpmw_> How's things?
[22:16:44] <robin_sz> just fine :)
[22:17:00] <robin_sz> conducted an interesting experiment today
[22:17:12] <bpmw_> Has alex_joni been around today?
[22:17:20] <robin_sz> not seenhim
[22:17:26] <robin_sz> seen anonimasu
[22:17:28] <bpmw_> Oh, what?
[22:17:34] <robin_sz> and swpadnos though
[22:17:47] <robin_sz> and Imperator ...
[22:17:50] <robin_sz> thats about it ...
[22:18:04] <robin_sz> oh, we always wanted to know ...
[22:18:23] <robin_sz> just how thick a piece of steel a .223 rifle bullet would go through :)
[22:18:44] <bpmw_> and!
[22:18:55] <robin_sz> well ,, we still don't know ...
[22:19:06] <robin_sz> but .. its "more than 8mm" ;)
[22:19:25] <bpmw_> so much for kevlar:)
[22:19:55] <robin_sz> kevlar vests will save your from handgun rounds
[22:20:06] <robin_sz> but a rifle paks 5 times the energy
[22:20:53] <robin_sz> anyway .. it creamed through 8mm steel plate .. no problem.
[22:21:44] <bpmw_> Thats for sure. I shot a friends HP rifle at a sand pit a couple of years ago, couldn't hear for 3 hours after. It was kind of exilerating though.
[22:23:30] <bpmw_> Hey robin where in uk are you?
[22:26:18] <bpmw_> bpmw_ is now known as bpmw_[A]
[22:26:18] <bpmw_[A]> * bpmw_[A] is now away - Reason : Putting roast on BBQ!
[22:28:00] <robin_sz> middle bit
[22:33:50] <fenn> robin_sz: try putting two 4mm plates with a sheet of styrofoam between them
[22:34:37] <robin_sz> fenn: 'k ...
[22:34:53] <robin_sz> how thick?
[22:34:57] <bpmw_[A]> How do you make yourself as back?
[22:34:58] <fenn> i want a written report with photos by tomorrow morning
[22:35:10] <robin_sz> might be tricky
[22:35:35] <robin_sz> how thick styrofoam?
[22:35:48] <fenn> robin_sz: use the blue foam insulation like for houses, it's usually ~1cm
[22:35:54] <robin_sz> 'k
[22:36:12] <fenn> dunno if it will work.. but i wanna find out
[22:36:13] <robin_sz> did you see that report on the dead M1 tank?
[22:36:24] <fenn> no you said something about it though
[22:36:36] <fenn> thought it was a battlefield laser?
[22:36:40] <robin_sz> the hull is 10" thick ...
[22:36:55] <robin_sz> nah .. HEAT round ..
[22:36:59] <robin_sz> shaoed charge
[22:37:03] <robin_sz> shaped
[22:37:17] <bpmw_[A]> A rail gun will go through that! easy
[22:37:38] <robin_sz> amazing .. drilled a 7mm hole through 10" of armour
[22:38:01] <robin_sz> rail guns are not exactly portable
[22:38:28] <bpmw_[A]> Neither are lasers powerful enough to do that!
[22:38:36] <robin_sz> well sure ...
[22:38:41] <robin_sz> but they exist ...
[22:38:50] <robin_sz> dunno if battlefield rail guns exist
[22:39:16] <robin_sz> the battlefield lasers are scary ...
[22:39:27] <robin_sz> gas dymanic lasers,
[22:39:38] <bpmw_[A]> I'm sure there are alot of things out there that we may never know about!
[22:39:54] <robin_sz> consume around 0.5 tonne of fuel per shot
[22:40:55] <fenn> heh how many hours does it take to recharge the capacitors?
[22:40:59] <bpmw_[A]> Robin just curious, do you read Jane's?
[22:41:29] <robin_sz> fenn: none. it doesnt have any. It basically a rocket motor with mirrors strapped across the cavity
[22:41:42] <robin_sz> bpmw_[A]: not recently
[22:41:44] <fenn> say what??
[22:41:53] <robin_sz> gas dynamic laser ...
[22:42:05] <fenn> point me to a tutorial on gas dynamic lasers please
[22:42:37] <bpmw_[A]> bpmw_[A] is now known as bpmw_
[22:43:50] <robin_sz> http://repairfaq.ece.drexel.edu/sam/CORD/leot/course01_mod11/m1-11f18.jpg
[22:45:19] <bpmw_> So does the laser guidr the rocket of actually fire it?
[22:45:42] <robin_sz> in a gas dynamic laser?
[22:45:48] <robin_sz> neither
[22:45:58] <bpmw_> Oh?
[22:46:03] <robin_sz> you know how a laser works?
[22:46:15] <fenn> do they add thorium or something that glows to the gas stream?
[22:46:15] <robin_sz> two mirrors across a cavity
[22:46:17] <bpmw_> basically
[22:46:28] <robin_sz> and the cavity has highly energized gas
[22:46:37] <robin_sz> bouncy bouncy go the electrons
[22:46:42] <robin_sz> zap goes the light
[22:46:43] <robin_sz> ?
[22:47:20] <bpmw_> Interesting!
[22:47:20] <robin_sz> well, the hot gases in a rocket motor are active enough ...
[22:47:33] <robin_sz> so you just strap some mirrors across the cavity
[22:47:36] <robin_sz> fir it up
[22:47:44] <robin_sz> and zap your enemies
[22:47:53] <fenn> wow that simplifies all my evil plans significantly :)
[22:47:56] <robin_sz> insane power levels
[22:48:06] <robin_sz> like, severall megawatts
[22:48:15] <robin_sz> for say 2 seconds
[22:48:37] <bpmw_> Thats alot of energy
[22:48:47] <robin_sz> yep
[22:49:02] <robin_sz> they haul 1 tonnes of fuel in a bowser
[22:49:10] <robin_sz> and chew it up in 20 shots
[22:49:23] <bpmw_> Whats a bowser?
[22:49:51] <robin_sz> trailer tank
[22:50:00] <bpmw_> Got it!
[22:53:19] <robin_sz> http://www.detnews.com/pix/2002/11/09/laserwp.gif
[22:53:32] <robin_sz> notice the "exhaust" on the laser building
[22:55:17] <bpmw_> Hey that pretty cool!
[23:02:44] <bpmw_> cradek, you there?
[23:05:39] <bpmw_> Hey Robin do you have any experience with Quadrature?
[23:07:55] <cradek> bpmw_: yeah
[23:07:55] <bpmw_> Anybody?
[23:09:04] <bpmw_> cradek, I got some new drivers to test out but they wont work on step/dir only quadrature.
[23:09:17] <robin_sz> quadrature? for drives?
[23:09:38] <robin_sz> we gave up on that .. I did have it going on emc ...
[23:09:52] <bpmw_> ya inputs are CW and CCW!
[23:10:09] <robin_sz> but I got confused as to which drivers supported it and which didnt
[23:10:20] <cradek> * lpg_phase_drive()
[23:10:20] <cradek> * Routine to compute and output the phase drive bits needed by quadrature
[23:10:20] <cradek> * phase stepper drive systems like the TMG (The Motion Group) electronics
[23:10:26] <robin_sz> seems steppersegmotqueue doesnt ...
[23:10:28] <cradek> emc1 supports it with STEPPING_TYPE 2
[23:10:54] <robin_sz> cradek: in freqmod and steppermod?
[23:10:59] <bpmw_> I'm on emc2
[23:11:11] <cradek> at least freqmod
[23:11:19] <cradek> bpmw_: I don't know squat about emc2
[23:11:28] <robin_sz> likewise
[23:11:42] <robin_sz> read the docs ;)
[23:11:47] <bpmw_> Ok!
[23:12:13] <robin_sz> I used it briefly on freqmod
[23:12:20] <cradek> It supports up to 8 pulse generators. Each generator can produce
[23:12:20] <cradek> several types of outputs in addition to step/dir, including
[23:12:20] <cradek> quadrature, half- and full-step unipolar and bipolar, three phase,
[23:12:22] <cradek> and five phase.
[23:12:25] <robin_sz> but couldnt get it to work with segmot
[23:12:37] <cradek> if the comment is to be believed, there may be support in emc2
[23:12:43] <robin_sz> kew;
[23:12:44] <robin_sz> l
[23:13:09] <bpmw_> What docs, only ones I can find are for emc1
[23:13:37] <cradek> the documentation is written in C
[23:13:56] <bpmw_> ?
[23:14:02] <robin_sz> code comments
[23:14:13] <cradek> sorry, that's a smartass way of saying there is no documentation, you have to look at the code
[23:14:48] <robin_sz> jmk documented some HAL stuff nicely
[23:15:01] <bpmw_> OH. I guess I'll have to wait for jmk.
[23:15:54] <cradek> in core_stepper.hal, change the line loadrt stepgen cfg="0 0 0"
[23:16:03] <cradek> to loadrt stepgen cfg="1 1 1"
[23:16:05] <bpmw_> to 222
[23:16:29] <cradek> oops, maybe it is 2 2 2
[23:17:12] <cradek> yep
[23:17:51] <bpmw_> alex_joni, gave me some instructions last night on how to change hal and pinout but something wrong. getting error trying to start emc
[23:18:36] <cradek> now you tell us
[23:18:39] <cradek> what's the error?
[23:19:28] <bpmw_> HAL: ERROR: pin "stepgen.0.Cw" not found
[23:20:35] <cradek> the two bits are probably named stepgen.0.PhaseA and stepgen.0.PhaseB
[23:21:31] <bpmw_> Thats what alex said to call them, but I went for Cw and Ccw. That could be the problem?
[23:21:51] <cradek> yes
[23:22:20] <cradek> besides your names making no sense for quadrature encoding, you can't call them whatever you want since they are outputs from the stepgen module.
[23:23:01] <fenn> bin/halcmd show pin | grep stepgen
[23:23:08] <bpmw_> I thought since I did newsig XCw bit I could name them anything!
[23:23:53] <bpmw_> Ok, I will change name as was originally suggested and give it a try!
[23:24:04] <fenn> you will need to use halcmd if you want to muck around with hal
[23:24:08] <cradek> great, good luck
[23:25:25] <bpmw_> fenn, just make a copy in text editor and seems to work fine.
[23:26:49] <bpmw_> Ok, thanks for the info. Have to go and check on roast. Bye for now!
