[00:30:45] <lilalinux> lilalinux is now known as lilalinux_away
[02:17:54] <Jymmm> I love it!!! http://money.cnn.com/2009/12/23/smallbusiness/i4i_microsoft_lawsuit/index.htm
[02:19:15] <eric_unterhausen> software patents are evil
[02:19:38] <Jymmm> It's not a software patent, it's a technology patent
[02:29:04] <eric_unterhausen> looks like they patented something that was fairly obvious and part of what XML is all about anyway
[02:33:32] <MattyMatt> how did they earn the $10m they used?
[02:34:02] <eric_unterhausen> apparently they sell software
[02:34:15] <eric_unterhausen> not a classic patent troll company
[02:37:53] <MattyMatt> ah well, when somebody invents RoboLawyer, we can all sue each other constantly without bringing the economy down
[02:38:16] <MattyMatt> it's all nonsense to be avoided until then
[02:41:40] <MattyMatt> I suppose I should patent robolawyer :) lend me $1600? (per territory, approx)
[02:44:54] <Jymmm> MattyMatt: Sure, at 100% per day
[02:46:19] <MattyMatt> I should find a partner who understands 49% is less than half
[02:46:59] <Jymmm> MattyMatt: No, that's 100% INTEREST PER DAY, till you pay back the $1600
[02:47:31] <MattyMatt> oh it would have to be on a contingency basis :)
[02:48:02] <eric_unterhausen> reminds me of the ad that said "reduces cholesterol by 52%, that's about half"
[02:48:07] <Jymmm> MattyMatt: Sure, the contingency is if you want to keep your legs or arms
[02:48:35] <MattyMatt> already used up all my limbs on my last two ventures
[02:49:11] <Jymmm> MattyMatt: NP, please place your crotch in the vise and bite down on this stick.
[02:49:39] <MattyMatt> momma sold them on my first venture
[02:49:58] <Jymmm> See, even your momma dont trust ya!
[02:50:16] <MattyMatt> of course not, I'm (was) a man
[02:50:26] <MattyMatt> she's a tifle bitter
[02:50:31] <MattyMatt> ^trifle
[02:51:15] <MattyMatt> I used to go on women's lib marches with her too. I thought I was on her side
[02:52:00] <MattyMatt> ah well, my kidneys will still raise a stake
[02:54:26] <MattyMatt> it seems a shame to break up a matched pair, but they fetch more individually
[02:57:06] <SWPadnos> remember the large bottles of soda that proclaimed "50% more than a 2-liter bottle"
[02:57:13] <SWPadnos> (those were, of course, 3-liter bottles)
[02:57:51] <SWPadnos> and who can forget the "diet bread", which had two fascinating statistics on the package:
[02:57:54] <Jymmm> I just bought one last week
[02:57:57] <SWPadnos> "half as many calories per slice"
[02:58:01] <Jymmm> the 3L of soda
[02:58:08] <SWPadnos> "twice as many slices per loaf!"
[02:58:19] <SWPadnos> (I'm not kidding)
[02:59:17] <Jymmm> Yeah half thickness slices
[02:59:24] <SWPadnos> ding ding ding!
[02:59:46] <SWPadnos> actually, I think they may have said there were twice as many servings per loaf, not slices
[02:59:48] <Jymmm> works for me
[03:01:16] <Jymmm> I am not buying a ABC extinguisher off CL tyvm!
[03:01:30] <Jymmm> http://sfbay.craigslist.org/pen/bfs/1524085415.html
[03:01:31] <SWPadnos> "slightly used"
[03:01:53] <Jymmm> Not a dry chem one at least. Newer CO2, sure
[03:02:45] <Jymmm> ah, it's a out of business business, still.
[03:03:44] <Jymmm> This just spells "Bust Me" all over it... http://sfbay.craigslist.org/eby/for/1524084116.html
[03:04:50] <Jymmm> Yeah call the number, I'm sure the ATF has it already backtraced
[03:06:38] <eric_unterhausen> I have some chronic pain, sign me up
[03:07:06] <Jymmm> You have the right to remain silent...
[03:07:48] <eric_unterhausen> are they still harassing the medical mj suppliers
[03:07:50] <eric_unterhausen> ?
[03:12:03] <MattyMatt> nice bud, but they all look like the same variety to me. purple should actually be a bit purple
[03:52:05] <MattyXM> it looks like a GM hybrid with a hyacinth as a live plant
[04:18:08] <danimal_garage> hmm so i'm trying to use my 7i37 to turn on and off my VFD, and it seems like there's too much resistance when it's off, so the vfd is contantly on
[04:18:35] <danimal_garage> apparently my vfd is sensative
[04:19:20] <danimal_garage> any way to fix this?
[04:19:56] <danimal_garage> maybe a resistor in line or something?
[04:21:50] <MattyXM> relay is the industrial solution
[04:22:28] <danimal_garage> i was waiting for that
[04:22:35] <danimal_garage> darn
[04:22:44] <danimal_garage> ok, thanks
[04:23:06] <MattyXM> if it's one digital signal to another, it could just need a pull-down or pull-up
[04:23:15] <MattyXM> don't give up on my say so :)
[04:23:39] <danimal_garage> i think it is
[04:24:09] <danimal_garage> it's not much work to throw in some relays, it's already half done
[04:24:20] <MattyXM> sounds like VFD wants beefy signals and the mesa is only giving TTL
[04:24:30] <danimal_garage> yea
[04:25:08] <danimal_garage> no biggie, i'll just throw in the relays
[04:25:21] <danimal_garage> thanks for the confirmation
[04:25:58] <danimal_garage> i'm excited, i made a lot of progress (for me) today
[04:27:19] <MattyXM> I got my B axis done. I attached toolmount to Z by a single bolt with wingnut :)
[04:28:02] <danimal_garage> nice, i wish i could do that
[04:28:12] <MattyXM> I'll put a protractor behind it and call it a manual B
[04:28:18] <danimal_garage> haha
[04:29:14] <MattyXM> a dremel on the end of an axis is quite a useful tool in itself, I think
[04:29:36] <danimal_garage> i bet
[04:30:10] <MattyXM> with another stepper or manual rotary, it could be a gear cutter
[04:31:17] <MattyXM> this is why I'd like to put as much smarts in each axis as possible. the moving table has other uses too
[04:32:30] <MattyXM> I'll need lots of very small PC with a real-time network to do it with emc2 I think
[04:32:33] <danimal_garage> i'd just be happy if my 3 axises were working good
[04:32:49] <MattyXM> yeah me too
[04:33:27] <danimal_garage> which mine are, for a change
[04:34:06] <danimal_garage> once my iron heats up, i can get these relays hooked up, and i'm going to get dinner
[04:34:15] <danimal_garage> i'm starving!
[04:34:25] <MattyXM> ironically it's my best axis that's holding me up now. I need one flexible motor coupling because the ballscrew unit is too solid
[04:35:41] <MattyXM> the M8 shafts can ease to accomodate my homemade solid couplings
[04:36:29] <danimal_garage> cant get the motor colinear enough?
[04:37:16] <MattyXM> not with my first 5 attempts :) I've got enough brass left for a few more goes
[04:37:55] <danimal_garage> lol
[04:38:00] <MattyXM> I'll make split connectors with dogs. that'll reduce wastage
[04:38:53] <danimal_garage> good idea
[04:38:55] <MattyXM> and less depth to drill
[04:40:14] <MattyXM> I might even save halves of my prior efforts
[05:01:59] <danimal_garage> WOOHOOO!! my vfd works now
[05:02:21] <danimal_garage> and on single phase :)
[05:03:49] <danimal_garage> and my spindle control buttons on my front pannel work too
[05:11:46] <MattyXM> yippidy doo :) save it a plate of dinner
[05:12:35] <MattyXM> teach it to play Silent Night on the VFD & steppers
[05:13:03] <MattyXM> oh I'm so gonna do that in gcode before next year
[07:24:16] <Jymmm> Anyone near Sparks NV... http://sfbay.craigslist.org/sfc/tls/1524142233.html
[09:08:09] <MarkusBec_away> MarkusBec_away is now known as MarkusBec
[09:31:04] <alex_joni> Happy/Merry <insert winter celebration of choice>
[11:13:41] <jthornton> * jthornton says Merry Christmas from Poplar Bluff Missouri
[12:14:12] <jthornton> http://www.linuxcnc.org/component/option,com_kunena/Itemid,20/func,view/catid,10/id,1374/lang,english/
[12:26:59] <lilalinux_away> lilalinux_away is now known as lilalinux
[13:41:01] <tom3p> Merry Christmas from Chicago, Illinois, USofA
[13:44:48] <tom3p> my italian friend Mauro Bada & Jack Klein & I decided to go across the river into Canada, to eat at the Tunnel BarBeQue.
[13:45:01] <tom3p> The border guard asks me "country of origin" ? I sez U S A.
[13:45:13] <tom3p>  He looks at Jack & Jack sez U S A and he looks at Mauro ( who's from Switzerland and hasnt brought his papers today ),
[13:45:14] <tom3p>  and Mauro sez "OOO Esss Ahh", the guard doesnt notice and waves us in. good baby back ribs :)
[13:46:23] <SWPadnos> it's the reverse trip that's hard :)
[13:52:39] <Guest413> anyone on that might be able to help me get EMC2 installed? I am having some troubles getting it installed on a dell GX280
[13:54:27] <Guest413> the live CD boot and the install boot options both only come up to a command prompt but wont load to the desktop
[13:55:01] <Guest413> well ok this time I got a long list of errors, hmm
[13:56:15] <Guest413> ok lol this time it gave me errors but is booting to desktop
[13:56:33] <jthornton> sounds like your making progress :)
[13:57:10] <Guest413> lol makes no sense, oh well if I can get the install to run from here I will be good
[14:05:34] <Guest413> ok i guess it was a bad Harddrive, swapped that out and its going smoothly now.
[15:41:36] <jt-plasma> I had the same problem once and a new harddrive solved it too
[17:54:50] <Jymmm> Merry Christmas!
[18:12:37] <Jymmm> What is it? http://sfbay.craigslist.org/sby/tls/1524316070.html
[18:13:30] <jt-plasma> variable speed disk drive
[18:13:43] <jt-plasma> with power adjust
[18:14:05] <Jymmm> disk drive?
[18:14:12] <jt-plasma> right angle drive with an encoder
[18:14:23] <Jymmm> um, ok.
[18:14:25] <jt-plasma> yea, two disks at an angle
[18:14:39] <jt-plasma> when you crank the motor up and down the ratio changes
[18:14:47] <jt-plasma> friction disk drive
[18:14:49] <Jymmm> ah
[18:16:23] <jt-plasma> this one is different that all the others I've had my hands on... it rotates the motor on an offset
[18:16:51] <jt-plasma> hey Jymmm come on over playing with insulation is fun :)
[18:17:20] <Jymmm> jt-plasma: Sure, you get in the attic with the hose, and I'll fill the hopper for ya!
[18:19:28] <jt-plasma> bats
[18:35:02] <danimal_garage> merry christmas
[18:35:48] <danimal_garage> didnt think anyone would be on today
[18:43:49] <jt-plasma> * jt-plasma wonders if I want to jump up and wire the quad outlet or wander down to the beer cave then wire the outlet... I think I take option 2
[18:47:10] <danimal_garage> sounds like a plan
[18:47:29] <danimal_garage> i got my vfd working last night
[18:47:52] <danimal_garage> works good
[18:48:06] <jt-plasma> cool, I got done insulating the attic a few minutes ago
[18:48:12] <danimal_garage> nice!
[18:48:33] <jt-plasma> got a couple of quad outlets to wire up on the north wall next
[18:48:47] <danimal_garage> yea, same here
[18:48:52] <jt-plasma> slowly picking up the extension cords that snake all over this place
[18:48:57] <danimal_garage> haha
[18:49:02] <danimal_garage> i ran mine through the rafters
[18:49:29] <jt-plasma> I had the whole garage on a 6-4 SO cord for a few years
[18:50:03] <jt-plasma> and two outlets with two extension cords made from 8-4 SO cord with quads on the ends
[18:50:04] <danimal_garage> i have 3 quad outlets on one side of the garage, still gotta run some conduit up and over so i can tackle the second side
[18:50:52] <danimal_garage> thats alot of extention cords
[18:51:19] <jt-plasma> I have three of those LOL
[18:51:24] <danimal_garage> my mill seems to work fine on single phase
[18:51:41] <danimal_garage> lol
[18:51:45] <jt-plasma> I need to put a post right next to this computer with a couple of quads on it
[18:51:50] <jt-plasma> cool
[18:52:11] <jt-plasma> * jt-plasma steps over to wire one up
[18:52:24] <danimal_garage> i do get a regenerative voltage overload under decelleration alarm sometimes though
[18:52:52] <danimal_garage> i slowed doen the decel, but i'd like to figure out whats going on
[18:53:59] <danimal_garage> i wish i'd just coast to a stop, i gotta figure out the parameter for that
[18:54:39] <cradek> I found a setting on my automation-direct for 'slow down as fast as you can without faulting'
[18:54:49] <cradek> I don't remember the details but that's sure what I wanted
[18:55:18] <danimal_garage> yea, thats what i want too!
[18:55:24] <cradek> keep looking :-)
[18:55:57] <cradek> or, if lunch is over, take the heating element out of your oven and wire it up as a brake
[18:56:04] <danimal_garage> what i'd like is to put another air selanoid on the brake, so it'll stop the spindle quickly
[18:56:29] <cradek> yeah you can't beat a mechanical brake
[18:56:38] <danimal_garage> so i dont really want the vfd to slow it down, i'd prefer if it could just cut power when it gets the spindle stop signal
[18:57:17] <danimal_garage> i thought my old vfd could do that, not sure about this one
[18:57:39] <danimal_garage> however, i dont know how that'd work with rigid tapping
[18:57:52] <danimal_garage> once i get an encoder hooked up
[18:58:57] <danimal_garage> is it safe to overrev the motor by increasing the frequency?
[18:59:41] <danimal_garage> i'd like to have a little gear reduction, then just increase the frequency over 60hz if i want to spin fast
[18:59:52] <danimal_garage> that way i have decent low end torque
[19:26:48] <Jymmm> Merry Chimpmas!!! http://www.cnn.com/video/#/video/us/2009/12/25/zarrella.chimpanzee.christmas.cnn
[19:40:18] <danimal_garage> i just removed my in-wall a/c unit since it's like 25 years old, and the idiots didnt even put headers or anything in, they just cut the studs
[19:40:44] <skunkworks> whats wrong with that?
[19:40:54] <danimal_garage> they boxed the hole in with 1x4's
[19:40:58] <skunkworks> heh
[19:41:01] <skunkworks> '_
[19:41:04] <danimal_garage> it's a load bearing wall
[19:41:05] <skunkworks> ;)
[19:41:46] <danimal_garage> so i had to cut the hole even bigger so i could get to studs
[19:42:06] <skunkworks> Jymmm: if I did it right.. the smp kernal has been running for a few days now. latency is around 13000
[19:42:12] <danimal_garage> not sure what to do with the cut stud
[19:42:43] <danimal_garage> i was thinking about just patching it
[19:42:43] <Jymmm> skunkworks: Well, you gonna run some parts?
[19:42:53] <skunkworks> I don
[19:42:55] <danimal_garage> 1300 is decent
[19:43:03] <danimal_garage> opps 13000
[19:43:10] <danimal_garage> is still decent
[19:43:26] <danimal_garage> i have no clue what mine is
[19:43:28] <Jymmm> skunkworks: ?
[19:43:29] <skunkworks> I don't really need the latency - I am going to use it to play with mesa hardware.
[19:44:05] <Jymmm> skunkworks: WTH?! Go make some swarf already!!!
[19:44:12] <danimal_garage> yea, i run mesa hardware too so i wasnt too concerned with it. i think i was somewhere around 12000-15000
[19:44:16] <Jymmm> skunkworks: forget that mesa crap!
[19:44:22] <danimal_garage> ha
[19:44:52] <skunkworks> I have one of the goal3 motherboards that runs the gantry. better latency
[19:45:09] <danimal_garage> cool
[19:45:39] <danimal_garage> i wonder what my lathe's pc is going to run, it's a dell with a p4. i'm assuming not terribly great
[19:46:13] <danimal_garage> my compaq server on my mill with a 1.4ghz p3 is pretty decent though
[19:47:14] <danimal_garage> off i go to patch my wall, happy holidays guys.
[21:05:46] <Guest869> Guest869 is now known as skunkworks
[21:52:48] <jt-plasma> well that is one extension cord not under my feet anymore :)
[21:58:23] <cradek> arg, my new DLT1 drive can't use tapes that were previously used in a DLTx000 drive even though they're the same tapes
[21:58:43] <cradek> they have to be either new or degaussed (and neither of my degaussing tools is enough)
[21:59:06] <jt-plasma> Yea! only 2 circuits left to transfer to the new panel
[21:59:07] <jt-plasma> cradek: does your Hardinge turrent use 12v or 24v for the encoder?
[21:59:43] <cradek> I think everything on the hnc is 12v
[22:00:31] <jt-plasma> looks like everything on the chnc 1 is 24v robh has one 12v thing on his superslant the turrent encoder
[22:01:04] <Jymmm> cradek: that's dumb/stupid
[22:01:31] <cradek> Jymmm: I guess it's a different type of head - the new one can't erase what the old one put there - it's too weak
[22:01:56] <Jymmm> cradek: what is this new drive?
[22:02:14] <cradek> VS80 aka DLT1
[22:02:21] <cradek> http://www.audiolabelectronics.com/Degserv.htm
[22:02:39] <cradek> these guys will erase the tapes for $2 ea
[22:03:08] <Jymmm> surely ou can make one
[22:03:58] <cradek> I don't know - the ones I have aren't enough - I don't know what it takes
[22:06:07] <cradek> http://www.pcconnection.com/IPA/Shop/Product/Detail.htm?sku=5711531&oext=1038A&ci_src=14110944&ci_sku=5711531
[22:06:59] <Jymmm> $2000 OUCH!
[22:07:52] <Jymmm> http://degausser.com/
[22:08:39] <Jymmm> This is the kind I've used for TV's... http://www.datadev.com/degausser-small-office-monitor-tv-television-dc13.html
[22:09:08] <cradek> yeah I'm positive that kind of thing is not enough to do it
[22:09:34] <cradek> anything for cassette/videotape/tv isn't going to work (I have that kind of stuff)
[22:10:14] <cradek> oh well I'll just buy another damn tape drive on ebay
[22:11:07] <Jymmm> You sure you can't just take apart a transformer, and play aorund with one tape and see what happens?
[22:11:29] <Jymmm> Erasure via degaussing may be accomplished in two ways: in AC erasure, the medium is degaussed by applying an alternating field that is reduced in amplitude over time from an initial high value (i.e., AC powered); in DC erasure, the medium is saturated by applying a unidirectional field (i.e., DC powered or by employing a permanent magnet). A degausser is a device that can generate a magnetic field for degaussing magnetic storage media.[3]
[22:11:51] <Jymmm> Apply AC and gently reduce the level
[22:12:10] <cradek> tried that (video tape eraser)
[22:13:01] <cradek> I guess I could try a bigass magnet, but that seems unlikely to work
[22:13:22] <Jymmm> electtro magnet might work
[22:18:49] <Jymmm> cradek: maybe find a sony crt on CL for free and rip out the degausser from it
[22:19:15] <Jymmm> if it can do a 22" crt, I'm sure it be string enough for a tape
[22:19:19] <Jymmm> strong
[22:19:42] <archivist_emc> tape degausers are much bigger than crt ones
[22:20:28] <cradek> haha http://old.nabble.com/bulk-erasing-DLT-tapes-(or,-more-specifically,-NOT)-td14967365.html
[22:22:13] <archivist_emc> or just get new tapes :)
[22:22:56] <cradek> sadly I have dozens and dozens already
[22:23:04] <cradek> much cheaper to buy a different drive
[22:26:00] <Jymmm> Can I Erase (Degauss) My SDLT Tape Cartridge?
[22:26:00] <Jymmm> Yes if you use the proper equipment and follow the procedure correctly.
[22:26:01] <Jymmm> SDLT and DLT tapes are written very powerfully onto tape that has a very high retention characteristic. The degausser should be capable of generating a magnetic flux of at least 4,000 Oersteds (Oe) and the tape should be passed through the unit, rotating it 90 degrees at a time four times. This ensures complete erasure.
[22:31:51] <Jymmm> I've always been chicken to make one, as I'm not sure when a conductor becomes an inductor and just not a dead short across mains =)
[22:36:38] <archivist_emc> my degauser designed for 1" video tape takes amps at 240, no idea of the field strength though, probably 10A or so
[22:57:21] <frallzor> anyone happen to have a danfoss vfd? =)
[23:12:16] <jt-plasma> well the temporary-temporary panel is removed... three more circuits left on the temporary panel to move to the permanent panel
[23:17:07] <Jymmm> jt-plasma: new service?
[23:20:48] <jt-plasma> I finally ran a 200amp service from the house to the garage a short while back, just now swapping things around
[23:21:13] <Jymmm> jt-plasma: what's the house, 400A service?
[23:21:23] <jt-plasma> 200a
[23:21:45] <jt-plasma> neither one draws much usually
[23:21:49] <Jymmm> ah
[23:22:02] <jt-plasma> propane heat from Hank Hill
[23:22:14] <Jymmm> You'll probably need the 400A service if you add any more smokers.
[23:22:35] <jt-plasma> I'll need to tap into some 3-phase for that
[23:22:44] <jt-plasma> 4160v I think
[23:22:45] <Jymmm> heh
[23:23:06] <Jymmm> I said smoker not crispy fried jerky
[23:23:21] <jt-plasma> fast as fast can be...
[23:23:34] <Jymmm> and would taste like shit
[23:23:45] <jt-plasma> * jt-plasma goes back into the attic to swap out the south lights feeder
[23:24:27] <Jymmm> better you than me =)
