[06:51:24] <Tom_itx> renesis, i've noticed that about SW
[06:57:13] <Tom_itx> enleth, this guy: https://encyclopediadramatica.se/index.php?title=Rucas&diff=prev&oldid=684573
[07:03:40] <asdfasd> lmao
[07:03:51] <asdfasd> is that real?!?
[07:04:06] <Tom_itx> were you really disconnected?
[07:04:10] <Tom_itx> mkay then.
[07:05:35] <Tom_itx> about a year ago several of us got into it with him and even moved it to a private irc channel where we ddos'd him and in reply he did the same to our servers
[07:08:01] <asdfasd> yes Im often disconnecred and cant connect after that for a long time
[07:08:16] <asdfasd> I ment about this guy
[07:10:12] <Tom_itx> i have logs if you care to read and don't believe me
[07:10:54] <asdfasd> I beleive you, but it is unbelievable ahahah
[07:11:38] <asdfasd> want to be a men and attack someone, but dont have the balls to attack proper network so go to the free irc...
[07:12:11] <Tom_itx> well the folks at freenode don't care to take action
[07:13:04] <jthornton> finally got the man door installed yesterday... on with the last bit of siding now
[07:13:19] <Tom_itx> soggy here
[07:13:58] <jthornton> same here, rained all day yesterday
[07:14:05] <enleth> Tom_itx: the guy is probably using a chinese botnet anyway, what can they do?
[07:14:06] <jthornton> and the day before
[07:14:11] <Tom_itx> 32°F Overcast
[07:14:33] <jthornton> 44°F Overcast here
[07:14:52] <Tom_itx> Rucas is of efnet aka oc80z on freenode
[07:15:00] <jthornton> radar is clear
[07:15:09] <asdfasd> something interesting noticed recently with skype
[07:15:34] <asdfasd> before was constantly memory issues until it crash
[07:15:46] <Tom_itx> The U.S. Geological Survey says a 4.5 magnitude earthquake struck northern Oklahoma early Monday
[07:16:01] <asdfasd> after blocking the advertisments on skype it is using much less memory and no more issues
[07:16:04] <jthornton> wow
[07:16:08] <Tom_itx> 80 mi s of me
[07:16:15] <jthornton> did you feel it?
[07:16:29] <Tom_itx> i don't feel anything when i'm asleep
[07:16:43] <Tom_itx> http://www.kake.com/home/headlines/45-earthquake-rattles-Kansas-Oklahoma-358729861.html
[07:16:46] <Tom_itx> local story
[07:17:04] <Tom_itx> we've been getting quite a few of them lately
[07:17:26] <Tom_itx> The quakes come after a 4.7-magnitude temblor hit northern Oklahoma on Nov. 19.
[07:20:17] <jthornton> http://showme.net/~fkeller/quake/maps4.htm
[07:20:52] <jthornton> se of me
[07:21:29] <Tom_itx> seems unusual here because it's so flat
[07:22:39] <Tom_itx> however USGS has instruments on the W side of town here and supposedly that's where this fault runs
[07:22:46] <Tom_itx> from Ok up thru KC
[07:23:36] <Tom_itx> i imagine you would feel an 8. quake
[07:24:12] <jthornton> yea that would even wake me up
[07:25:09] <Tom_itx> we usually feel them if awake etc since the ground is so hard packed
[14:38:44] -verne.freenode.net:#linuxcnc- [freenode-info] channel trolls and no channel staff around to help? please check with freenode support: http://freenode.net/faq.shtml#gettinghelp
[15:00:22] <_methods> jthornton: how much did your bp series 1 conversion cost you?
[15:04:10] <_methods> JT-Shop: or you
[15:04:11] <_methods> hehe
[15:04:33] <_methods> did you use all the existing servos and drives?
[15:52:26] <AndChat|407721> _methods: are you converting a boss or manual bridgeport
[16:07:11] <mrsun__> cnc converted boss ?
[16:07:47] <JT-Shop> I bought the BP with the Anilam already installed
[16:13:52] <duc> What's wrong with current controller
[16:15:49] <_methods> did you reuse the drives and servos?
[16:16:07] <XXCoder> check this out https://youtu.be/h2uWx7xl1go
[16:18:25] <JT-Shop> yes and the power supply
[16:18:38] <JT-Shop> and the MPG...
[16:18:54] <_methods> k
[16:19:28] <_methods> basically all you had to do was drop in 7i77 and hook up all the existing i/o stuff to it?
[16:19:31] * JT-Shop goes back to menards...
[16:19:40] <_methods> 5i25/7i77?
[16:19:41] <Erant> XXCoder: Yeah, I'm probably going to do that to mine
[16:19:43] <JT-Shop> pretty much
[16:19:52] <_methods> any gotchas you remember?
[16:20:09] <_methods> we have a series 1 at the shop i might be getting for a good price
[16:20:22] <_methods> but it's got some issues so i figured i'd just convert it
[16:20:25] <JT-Shop> I added a GS2 VFD for the spindle then later added an encoder to the spindle for rigid tappnig
[16:20:34] <_methods> ahhhhh
[16:20:37] <_methods> good idea
[16:20:39] <JT-Shop> manual mill?
[16:20:45] <_methods> no
[16:20:48] <_methods> eztrak
[16:20:53] <_methods> series 1 eztrak
[16:21:29] <JT-Shop> if the drives take +-10v and it has encoders it's an easy converstion
[16:21:33] <JT-Shop> conversion
[16:21:40] <JT-Shop> bbl
[16:21:44] <_methods> it's got the cleveland motion drives
[16:21:46] <duc> Encoder is really nice to have on spindle for VFD tuning
[16:21:47] <_methods> and servos
[16:22:13] <_methods> i'll have to check and make sure they are +/-10
[16:22:34] <_methods> guess it doesn't really matter since i'll just replace them if not
[16:33:51] <Deejay> gn8
[16:55:42] <CaptHindsight> when slitting 304 stainless with a 0.057" cutter would you go for more or less teeth with the same dia cutter?
[16:57:45] <cradek> get 10 of each style, you'll need them
[16:57:51] <CaptHindsight> heh
[16:58:06] <PetefromTn_> stainless usually likes an aggressive cutter
[16:58:21] <cradek> yes you sure don't want to rub
[16:58:29] <CaptHindsight> 5 vs 6.5 degrees per tooth
[16:59:14] <CaptHindsight> depth of the slit is only 0.050"
[17:01:18] <CaptHindsight> maybe I'll get some 303 instead
[17:40:16] <andypugh> According to a programme on the TV, every year we get through 360 trillion sticks of chewing gum. Somehow I don’t think that is right.
[17:43:57] <andypugh> That means that every person on earth buys 135 sticks a day, which in the UK at least would be ÂŁ3.50.
[17:47:39] <JT-Shop> I think their math is flawed... like linuxmint claiming to be the 4th most use OS, how do they know lol
[17:48:25] * JT-Shop is making oak standoffs for the conduit...
[17:51:47] <CaptHindsight> maybe 4th most downloaded
[17:52:20] <CaptHindsight> there's no way to tell how many installs are made from a single download
[17:52:53] <SpeedEvil> In some ways it would be nice f there was mre reporting.
[17:53:05] <SpeedEvil> It could for example be used to actually track drive/... reliability
[17:53:34] <CaptHindsight> or I download one copy of an ISO, install and bork it and reinstall vs fix weekly
[17:53:54] <JT-Shop> so how would linuxmint know how many copys of ubuntu is downloaded to compare
[17:54:57] <CaptHindsight> http://askubuntu.com/questions/80379/how-many-ubuntu-users-are-there-worldwide
[17:55:41] <CaptHindsight> guestimates
[17:56:48] <JT-Shop> 4' stick of 3/4 emt I put two offsets and one 90°... only took 3 tries to get it right
[17:57:22] <SpeedEvil> :)
[17:57:43] <SpeedEvil> JT-Shop: 'oh - this is too easy to actually bother properly marking it up'
[18:00:09] <DaViruz> the stepper drivers on my new emco machines seems to actually detect when a stepper loses steps
[18:00:22] <DaViruz> which halts the machine and gives a synchonization error
[18:00:30] <DaViruz> seems like a pretty useful thing to have on a stepper driver
[18:00:55] <SpeedEvil> Interesting, and not hard to do.
[18:36:28] <MattyMatt> not easy enough for every stepper driver tho
[18:37:36] <MattyMatt> I guess supplying the motor and driver matched makes it possible
[18:40:54] <MattyMatt> I'm assuming there's no encoder, as you wouldn't need a panic stop if you could make up lost steps more reliably
[18:41:11] <andypugh> Talking about stepper drivers, Zapp spammed me earlier with this drive:
[18:41:14] <andypugh> Talking about stepper drivers, Zapp spammed me earlier with this drive:
[18:41:26] <andypugh> Talking about stepper drivers, Zapp spammed me earlier with this drive: http://www.zappautomation.co.uk/electrical-products/servo-systems/ac-and-dc-brushless-servo-drivers/fd-range-346/fd112-aa-000-ac-servo-stepper-motor-driver.html
[18:43:22] <MattyMatt> meh, one more half bridge and it could do 5 phase stepper too
[18:49:19] <MattyMatt> I can see that driver being handy if you want to crack on with a build for an indecisive boss
[18:50:07] <MattyMatt> who can't count :)
[18:53:22] <MattyMatt> or maybe in a factory with a mix of motors. they are trying to push bundles of 30
[18:54:22] <andypugh> It’s a decent price for a brushless drive. The stepper-option is just a bonus.
[18:55:03] <JT-Shop> say goodnight Gracie
[18:56:14] <MattyMatt> arrivederci
[19:04:20] <MattyMatt> my ebike driver needs an upgrade, if I get more batteries :)
[19:05:16] <MattyMatt> on 24V it fails entirely to shift my weight on the gentlist incline
[19:05:56] <MattyMatt> gentleist? is it even I word? I can't f'ing spell it
[19:06:59] <malcom2073> It is now!
[19:08:08] <MattyMatt> superlative adjective: gentlest
[19:10:11] <MattyMatt> anyway, wintertime. I think I'll bring the batteries in and try my EDM on them
[19:11:24] <MattyMatt> ATX freaks and shuts down
[19:12:00] <MattyMatt> like instantly, no twitch from the solenoid at all
[19:16:30] <MattyMatt> here's an idea for a brushless AC driver. circular lead acid cell with 3 set of plates, half full of acid. slosh cell around to commutate
[19:19:05] <MattyMatt> that idea is so stupid I gotta go grab a beer
[19:26:45] <andypugh> MattyMatt: I think that peak RPM would be limited.
[19:26:55] <andypugh> Probably better to use a trough of mercury instead.
[19:27:18] <MattyMatt> liquid lithium
[19:27:51] <MattyMatt> or lithium electrodes at least, so the input motor can be smaller thanthe output one
[19:31:04] <MattyMatt> or make the cell flat and shallow, and have ultrasonic waves in the acid
[19:31:32] <MattyMatt> STUPID! DRINK BEER NOW!!!
[19:32:13] <andypugh> I just swapped the light fitting in my living room to one that hasn’t been smashed by a model helocopter (it’s only been like that for 4 years). I needed new bulbs, so got LEDs. Now I find that my dimmer won’t turn the LEDs off. Presumably the dimmer itself takes enough current to light LEDs (it’s a clever infra-red remote one, controlled by a spare button on the TV remote)
[19:33:24] <greg_> most LED bulbs stateside are dimmable now, but some list compatible dimmers
[19:34:08] <andypugh> These are dimmable bulbs.
[19:34:25] <andypugh> The problem ls that they only dim. They don’t turn off :-)
[19:35:08] <greg_> Oh, they don't turn off, so incadecent was pulling current even when off?
[19:36:10] <andypugh> I had CFL previously, those appeared to turn off, and would dim too. (though last time I ran with them dimmed for a long time, one started making noises and smells…)
[19:37:00] <andypugh> The dimmer only sees live and load, so presumably has to pass a bit of current to power itself.
[19:37:27] <greg_> almost of my CFL are dead now, 90% didn't make it 2 years let alone the "7 year warranty"
[19:38:13] <andypugh> Our government pushed CFL pretty heavily, then suddently LED came along, with better efficiency and none of the drawbacks.
[19:38:47] <malcom2073> Weird, I've never had a CFL died, I have a couple that I must have bought like 6-7 years ago
[19:38:51] <MattyMatt> I wish I'd bought more CFL when they 50p for 5. those last too
[19:39:08] <andypugh> But, I actually need more light in this room that the LEDs are giving, so I guess that some halogens will be going in.
[19:39:16] <malcom2073> I want to move to LED though, LED s are getting really nice
[19:39:40] <MattyMatt> the skinny ones with 2 loops seem to last. they don't burn out like the 3 loop ones
[19:40:04] <greg_> All brands too. Feit is a common Chinese brand, but Sylvania and Phillips maybe.
[19:40:07] <MattyMatt> just get more LED
[19:40:37] <MattyMatt> some of those programmable RGB strips
[19:41:16] <greg_> last week i replaced caps in LED drivers. GU10 bulbs. The only one that hadn't flickered or died in the year i had them had a Rubycon capacitor.
[19:42:44] <MattyMatt> I've had some cheap LED pop when the lamp was jiggled (wobbly B22) but it was the LEDs themselves that popped
[19:43:06] <Magnifikus> whttp://pastie.org/10593749 is this okay for linuxcnc? its rpi2 with 4.1.13 rt full kernel
[19:46:49] <MattyMatt> someone was saying yesterday that rpi2 is no better than rpi1 for latency
[19:47:14] <Magnifikus> yeah but rpi1 cpu is fast as a snake
[19:47:28] <Magnifikus> like you press left cursor and machine moves 5 sec later
[19:49:10] <MattyMatt> I get that on my Athlon 1.2 if GL preview is on
[19:49:30] <MattyMatt> more like 1 second, but it's still bloody annoying
[19:50:07] <Magnifikus> yeah dont like it
[19:50:13] <Magnifikus> esp when you jog z-axis down :D
[19:50:18] <MattyMatt> yep :)
[19:50:21] <Magnifikus> STOP FFS
[19:51:52] <andypugh> If that is a problem then there are real-time inputs for jogging with, unaffected by GUI larency
[19:52:13] <andypugh> Keyboard jogging is a bit risky on any machine, when you look at it.
[19:52:18] <Magnifikus> yeah working on hardware jog
[19:52:27] <Magnifikus> but now compiling machinekit lets see
[19:52:30] <MattyMatt> oh wow, I didn't know that'd help
[19:52:37] <Magnifikus> than i need to build my hal component to interface the fpga
[19:52:42] <Magnifikus> and than i care about jogging :D
[19:52:57] <andypugh> As for the RPi latency, I don’t know what the numebers mean. Which realtime system are you using?
[19:53:20] <Magnifikus> rt preempt full
[19:53:45] <Magnifikus> machinekit blog called xenomai dead cause rt preempt is getting better now
[19:54:01] <Magnifikus> but im not that critical anymore if i move the stepgen into the fpga also
[19:54:19] <Magnifikus> first try is pulsewidth setting
[19:54:29] <Magnifikus> and position feedback
[19:54:53] <andypugh> 105uS latency isn’t great, but PCW says that it is OK if you move stuff to FPGA, and if the FPGA compensates
[19:55:02] <malcom2073> Heh, I've crashed my machine on the beagleboneblack a couple times because of keyboard input lag
[19:55:36] <Magnifikus> maybe i can get it to use a specific core
[19:55:38] <Magnifikus> exclusive
[19:56:16] <andypugh> isolcpus is meant to do that (with RTAI, not sure about preempt)
[19:56:18] <CaptHindsight> like the idea behind isolcpus= ?
[19:57:06] <CaptHindsight> it was supposed to work with any kernel
[19:59:11] <Jymmm> Jiffy Popcorn?
[19:59:58] <Jymmm> CaptHindsight: http://weknowmemes.com/wp-content/uploads/2014/03/redneck-fire-alarm.jpg
[20:00:10] <CaptHindsight> even Orville Redenbuferebackers
[20:00:16] <Jymmm> heh
[20:00:17] <zeeshan> orville popcorn?
[20:00:50] <Jymmm> Orville Redenbacher
[20:01:20] <Jymmm> this dude http://a3.files.biography.com/image/upload/c_fit,cs_srgb,dpr_1.0,h_1200,q_80,w_1200/MTE1ODA0OTcxNDM2NzA1Mjkz.jpg
[20:01:45] <CaptHindsight> https://www.youtube.com/watch?v=rthHSISkM7A Jerry's House of Popcorn
[20:02:16] <CaptHindsight> 30 years ago
[20:02:19] <Magnifikus> where is an option to tell linux to stay of a specific core
[20:02:26] <Magnifikus> and when you just do taskset
[20:07:07] <andypugh> Magnifikus: Try isolcpus in the grub command line
[20:07:44] <andypugh> Magnifikus: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?The_Isolcpus_Boot_Parameter_And_GRUB2
[20:07:45] <Magnifikus> later ty first i need to compile machinekit that complains distro '' is unknown :)
[20:07:51] <Magnifikus> and i got uboot
[20:07:59] <Magnifikus> but thats cmdline.txt then
[20:08:09] <andypugh> Yes, I just remembered that you will be using uboot not grub.
[20:08:26] <Magnifikus> uboot is awesome
[20:08:35] <Magnifikus> on zynq i use it to bootstrap everything
[20:08:42] <Magnifikus> execute uboot via jtag
[20:08:52] <Magnifikus> and than load all stuff over ethernet :)
[20:09:18] <andypugh> Anyway, time to leave
[20:10:20] <CaptHindsight> http://www.denx.de/wiki/view/DULG/LinuxKernelArgs
[20:10:48] <CaptHindsight> I've only paid for the 5 minute kernel argument so I have to leave now as well
[20:11:34] <Magnifikus> nn
[20:18:31] <malcom2073> That moment when you go to send "I love you" to your significant other, but iphone sucks and you send it to your boss.
[20:20:04] <Jymmm> malcom2073: suck up
[20:20:18] <malcom2073> Haha that's what he said.
[20:20:39] <Jymmm> malcom2073: just be glad HE, isn't a SHE =)
[20:21:08] <malcom2073> Haha, amusing in that it makes it LESS awkward
[20:22:00] <Jymmm> But, if you had added 'man' at the end, then no problem.... "I love you man!" Cause then your boss would have know you weee just shitfaced at the time.
[20:22:13] <malcom2073> I'm on travel for work right now.... heh
[20:22:17] <Jymmm> ...and a happy drunk =)
[20:22:33] <CaptHindsight> http://4.bp.blogspot.com/-W1AGckheWRs/T6a_1rYG2EI/AAAAAAAAAAQ/0rs1AuEiQEA/s1600/RAMPS1.4schematic-errors.png seriously, they haven't fixed this?
[20:23:53] <malcom2073> Yeah, they should really update all the images all over the internet
[20:23:55] <malcom2073> :P
[20:24:45] <malcom2073> Or at least on their wiki, but meh
[20:25:17] <MattyMatt> if only wiki was user editable
[20:25:35] <malcom2073> If only people who noticed it would fix it.....
[20:26:34] <MattyMatt> actually I've given up on reprap wiki, because it has never remembered my login, so I've had to make a new account for each edit. v tiresome and the user names were getting silly
[20:26:46] <MattyMatt> MattyMattyMattyMatt etc
[20:52:35] <Tom_itx> anybody ever use a spaceball with SW?
[20:55:04] <zeeshan> youre a space ball!
[20:57:39] <malcom2073> I have a spaceball
[20:57:48] <malcom2073> But I don't have SW anymore
[20:57:56] <zeeshan> i have one too
[20:57:58] <zeeshan> but i hate it :P
[20:58:12] <zeeshan> <-ctrl,shift+middle mouse button type of person
[21:01:23] <os1r1s> Tom_itx I've used one
[21:01:42] <Tom_itx> what did you think of it?
[21:01:45] <Tom_itx> over a mouse
[21:01:58] <os1r1s> Much, much better
[21:02:02] <Tom_itx> zeeshan, SW and CATIA don't see eye to eye on mouse
[21:02:16] <os1r1s> It doesn't really replace the mouse, it really serves a different function
[21:02:23] <Tom_itx> os1r1s, was it just a ball or the whole damn mouse console thingie?
[21:02:35] <Tom_itx> os1r1s, such as?
[21:02:46] <zeeshan> http://www.3dconnexion.com/fileadmin/templates/images/3dx_category_page/smp_thumb.png
[21:02:48] <zeeshan> thats what i have
[21:02:52] <zeeshan> it collects dust now
[21:02:57] <os1r1s> Tom_itx I use the spacemouse pro
[21:03:04] <os1r1s> Similar to the one pictured above
[21:03:06] <Tom_itx> http://www.3dconnexion.com/products/spacemouse/spacepilot-pro.html
[21:03:15] <Tom_itx> the school here has a bunch of those
[21:03:21] <os1r1s> So one of the more frequent things I need to do is zoom around the model
[21:03:25] <Tom_itx> nobody uses them
[21:03:31] <zeeshan> scroll the mouse wheel up
[21:03:35] <zeeshan> to zoom in :P
[21:03:36] <os1r1s> rotate, zoom in, zoom out, etc
[21:03:39] <os1r1s> Its not the same
[21:03:44] <zeeshan> click middle mous ebutton
[21:03:50] <os1r1s> I can position my parts with much better accuracy
[21:03:52] <zeeshan> to rotate :P
[21:04:00] <os1r1s> Its still not the same
[21:04:03] <zeeshan> i can tell you this much
[21:04:08] <Tom_itx> http://www.3dconnexion.com/products/spacemouse/spacenavigator-for-notebooks.html
[21:04:12] <os1r1s> We have about 200 of those at work. And next near every engineer uses them
[21:04:13] <Tom_itx> is that usefull at all?
[21:04:18] <zeeshan> ive tried to use mine for a year
[21:04:24] <zeeshan> and i did not find that it made mre anymore productive
[21:04:36] <zeeshan> same here osr1r1s
[21:04:38] <zeeshan> most people have it
[21:04:42] <zeeshan> i notice its a preference thing
[21:04:44] <Tom_itx> way back when, i had a thumb ball mouse i used
[21:04:52] <Magnifikus> wow this zmq mess with machinekit, i got now 2 3 and 4 oO
[21:04:53] <os1r1s> Tom_itx That will help with the zooming/rotating/positioning
[21:05:04] <Tom_itx> but not selecting?
[21:05:09] <os1r1s> But I like the spacepilot becuase it gives you shortcut keys
[21:05:15] <os1r1s> To extrude, shell, etc, etc
[21:05:20] <os1r1s> So you can really zip along
[21:05:25] <zeeshan> press e to extrude
[21:05:28] <os1r1s> And the keys are programmable to the functions you like
[21:05:28] <zeeshan> :P
[21:05:30] <Roguish> Tom_itx: i have a SpaceNavigator and like it. works with ProE, SW, acad, mastercam, Ansys.....
[21:06:13] <Tom_itx> too bad CATIA and SW don't use the same mouse functions
[21:06:21] <Tom_itx> they didn't think that thru very well
[21:06:30] <os1r1s> Tom_itx You can set it in the software of the mouse
[21:06:32] <zeeshan> the only thing i would say in my opinion the space navigator is better at
[21:06:35] <os1r1s> So the same buttons do the same thing
[21:06:37] <zeeshan> is it's more smoother in positioning
[21:07:05] <Roguish> u may be able to 'reprogram' a bit.
[21:07:12] <Tom_itx> yeah
[21:07:26] <Tom_itx> i probably should get a 3 button mouse at least
[21:07:31] <os1r1s> Tom_itx I use SW on my laptop a lot. And when using a laptop the spacepilot makes life a ton easier
[21:07:38] <Tom_itx> i got a boxfull of 2 with wheel
[21:07:39] <malcom2073> Tom_itx: Still using the old 1 button? :P
[21:07:47] <os1r1s> If you only use it on a desktop, it may be less interesting
[21:07:57] <Roguish> good luck finding a real 3 button mouse.
[21:08:18] <Tom_itx> os1r1s, what do you mean?
[21:08:30] <Roguish> they're all the 2 + wheel. press the wheel for the middle button. PITA
[21:08:38] <os1r1s> Well, using a mouse with a laptop on your lap is a pain
[21:08:41] <Tom_itx> agreed Roguish
[21:08:44] <zeeshan> Tom_itx: why do you think you need a space navigator
[21:08:46] <os1r1s> And the laptop trays suck
[21:08:50] <zeeshan> what are you trying to accomplish?
[21:08:51] <Tom_itx> zeeshan i didn't say i did
[21:09:00] <os1r1s> But the spacepilot allows you to be very effective
[21:09:01] <zeeshan> do you think itll make you faster?
[21:09:03] <Tom_itx> i was asking because they have them at the local school
[21:09:12] <Tom_itx> not many get used
[21:09:16] <zeeshan> theres a reason for that
[21:09:19] <zeeshan> =P
[21:09:20] <os1r1s> zeeshan It doubles my speed on complex assemblies
[21:09:27] <Tom_itx> and that's the reason for asking... nimrod
[21:09:28] <zeeshan> os1r1s: you want a challenge?
[21:09:34] <zeeshan> lets make an assembly right now
[21:09:36] <os1r1s> zeeshan No
[21:09:37] <Tom_itx> haha
[21:09:38] <zeeshan> lets see who can do it faster :)
[21:09:39] <Tom_itx> here goes
[21:09:45] <Tom_itx> zeeshan... done!
[21:09:56] <zeeshan> im telling you!
[21:10:00] <os1r1s> I've got too much work to do prepping for a car delivery Friday
[21:10:00] <zeeshan> its a preference thing at the end of the day
[21:10:15] <zeeshan> some people swear by it, some don't
[21:10:16] <PetefromTn_> oh shit
[21:10:26] <os1r1s> Tom_itx If you can borrow one for a bit, give it a shot. I like it a lot. So do many of the engineers at work.
[21:10:45] <Tom_itx> i'm considering taking the catia class here
[21:10:52] <Tom_itx> i'll try it there if anything
[21:11:28] <Tom_itx> i know a guy that had an old spaceball he used with acad
[21:11:41] <Tom_itx> it ended up collecting dust too
[21:13:27] <Tom_itx> if i were gonna do it every day i'd probably look into something like it
[21:13:44] <Tom_itx> definitely try before buy though
[21:13:47] <zeeshan> the problem that i found wit hthe spaceball is
[21:13:53] <zeeshan> really what im used to
[21:14:00] <zeeshan> i use a-z for all my shortcuts
[21:14:20] <zeeshan> and arrow keys rolling the model in 90 degree increments
[21:14:43] <zeeshan> if i could find a mouse screen button that was smoother than the logitech g5
[21:14:53] <zeeshan> i'd be set!
[21:15:02] <Tom_itx> well right now all i have to try it on is my kid's surface pro3
[21:15:11] <Tom_itx> and i personally dislike them
[21:15:23] <zeeshan> thats not a fair test though :p
[21:15:27] <Tom_itx> i know
[21:15:35] <Tom_itx> but it does run pretty well on it
[21:15:37] <Tom_itx> catia that is
[21:15:39] <zeeshan> try it for a couple weeks
[21:15:44] <zeeshan> and form your own opinion
[21:15:46] <zeeshan> i think its worth a shot
[21:16:05] <Tom_itx> the surface is too small to do cad on imo
[21:16:14] <zeeshan> dude
[21:16:17] <zeeshan> i got a 24" monitor
[21:16:20] <zeeshan> and ive been looking for a 32"
[21:16:23] <Tom_itx> exactly
[21:16:27] <zeeshan> bu its TOO EXPENSIVE!!
[21:16:34] <zeeshan> i cant pay $699 for a monitor
[21:16:39] <zeeshan> i got this one for $70
[21:16:39] <zeeshan> :D
[21:16:40] <Tom_itx> sell your damn racecar :D
[21:16:47] <zeeshan> no, i have the money for it
[21:16:51] <zeeshan> but it is a waste
[21:16:54] <Tom_itx> no you dont
[21:17:02] <zeeshan> cause you know it'll drop value in 3 years
[21:17:03] <Tom_itx> you wanna pay off your house remember?
[21:17:14] <zeeshan> we redecided our plan
[21:17:16] <FinboySlick> Well, let's not poke too hard at the elephant in the room, but if you're running Catia, no monitor is too expensive.
[21:17:17] <zeeshan> not gonna kill ourself
[21:17:20] <zeeshan> 5 years instead of 2
[21:17:22] <Tom_itx> i know, everything drops in value over time
[21:17:53] <Tom_itx> FinboySlick, yeah it's $$$$$$$$
[21:18:02] <PetefromTn_> well I think I finally have my new scope rail design worked out and I am making the prototype right now ;)
[21:18:10] <Tom_itx> fortunately i got it free as a student copy
[21:18:30] <Tom_itx> but my bud gave about 75k for it
[21:18:39] <FinboySlick> What do they charge for it nowadays? Half of my Catia experience was on Sun workstations.
[21:18:51] <Tom_itx> his was on a sun workstation too
[21:19:04] <Tom_itx> i dunno what it runs since they ported it to windows
[21:19:42] <Tom_itx> but everybody around here uses it
[21:19:59] <FinboySlick> Well, I had a 'student' copy of p5 around the same time. Back then it was humongous at around 3GB, it must be like 2TB of DLLs nowadays.
[21:20:17] <zeeshan> FinboySlick: 25k
[21:20:37] <FinboySlick> Well, considering who uses it, it's not that bad.
[21:22:04] <Tom_itx> yeah
[21:22:35] <zeeshan> man then kitten
[21:22:41] <zeeshan> |
[21:22:46] <zeeshan> all over my keyboard
[21:23:35] <FinboySlick> Kitten on keyboard, I can understand. But why was there a man first?
[21:23:45] <zeeshan> :D
[21:25:19] <FinboySlick> With all the new stuff happening in OpenGL nowadays, wouldn't it be possible to write a much more streamlined lib than OpenCASCADE? Seems to be the only featurful CAD backend in the open source world.
[21:26:49] <Tom_itx> FinboySlick, have you used SW?
[21:27:06] <FinboySlick> Tom_itx: SolidWorks? Of course. I'm quite good at it actually.
[21:27:22] <Tom_itx> just wondered your opinion between the two
[21:27:43] <Tom_itx> not knowing alot about catia i think sw is simpler to use
[21:27:48] <zeeshan> FinboySlick: I Challenge you to a duel
[21:27:53] <Tom_itx> pfft
[21:28:07] <zeeshan> Tom_itx: i dojnt play video games
[21:28:12] <zeeshan> i need some entertainment
[21:28:16] <Tom_itx> heh
[21:28:18] <Tom_itx> i don't either
[21:28:29] <Tom_itx> you're pretty intertaining
[21:28:31] <zeeshan> and at work im doing stress calculations
[21:28:37] <FinboySlick> zeeshan: I'd have to boot into Windows :(
[21:28:38] <zeeshan> so my life is not being challenged
[21:28:50] <zeeshan> maybe i will get gta5
[21:29:01] <zeeshan> FinboySlick: i was kidding :P
[21:29:02] <CaptHindsight> I'd say that SW is easier to use than Catia, but Catia has more stuff
[21:29:10] <zeeshan> CaptHindsight: O RLY
[21:29:13] <Tom_itx> CaptHindsight, i agree
[21:29:14] <zeeshan> tell us what stuff it has
[21:29:20] <Tom_itx> it handles large assemblies better
[21:29:24] <CaptHindsight> NX has morer stuff or mostist
[21:29:30] <zeeshan> like
[21:29:34] <zeeshan> examples
[21:30:18] <CaptHindsight> and don't forget Creo :)
[21:30:28] <Tom_itx> catia won't let you draw multiple items on a sketch and extrude them independently
[21:30:46] <Tom_itx> that's one thing i like about SW
[21:30:59] <CaptHindsight> ID people tend to like Creo for its surface features
[21:31:22] <Tom_itx> i haven't gotten into surfaces with either one yet
[21:32:28] <FinboySlick> SW is no slouch with surfaces either, especially the later versions.
[21:32:40] <CaptHindsight> I get better at SW than the others but I make myself use NX as often as I can now
[21:33:15] <CaptHindsight> now I look for features in SW that aren't there
[21:33:34] <humble_sea_bass> Features waiting in the wings
[21:33:50] <humble_sea_bass> SW is priced so you can impulse upgrade every few years
[21:34:37] <CaptHindsight> I never used autocad much, I tend to import them into other applications
[21:34:54] <CaptHindsight> I did play with Inventor
[21:35:00] <Tom_itx> i never cared for acad
[21:35:04] <humble_sea_bass> Autocad is just 2d, anything beyond that is hacked in and bad
[21:35:33] <Tom_itx> i knew a guy that was pretty good with it
[21:35:36] <Tom_itx> 3d
[21:35:48] <humble_sea_bass> and with the Acad clones, many which are free, there is no need for it
[21:35:49] <Tom_itx> used ncpolaris to export the gcode
[21:36:24] <CaptHindsight> my beef was always trying to export some model into a photorealistic render program
[21:36:46] * zeeshan freeforms all the time in sw
[21:36:51] <humble_sea_bass> Tom_itx: getting good at 3d with ACAD is tantamount to learning to play concertos with rubber bands. possible but why
[21:37:10] <FinboySlick> It's been a little while since I played with Inventor, but anytime you tried to push it a bit beyond its comfort zone, it became infuriatingly unstable or just did something unexpected.
[21:37:12] <zeeshan> CaptHindsight: you havent mentioned one feature
[21:37:14] <zeeshan> that is missing! :P
[21:37:39] <CaptHindsight> from SW that's in NX?
[21:37:44] <humble_sea_bass> did they ever implement nurbs
[21:37:47] <zeeshan> yes capt
[21:37:51] <FinboySlick> Autodesk products, as far as I can remember always seemed to keep just enough bugs to keep you hoping the next upgrade would be better.
[21:37:52] <zeeshan> other than cam
[21:38:10] <zeeshan> autodesk products
[21:38:15] <zeeshan> are prolly the #1 drafting products
[21:38:16] <zeeshan> in the world
[21:38:24] <zeeshan> solidworks drafting doesn't even come close
[21:38:35] <humble_sea_bass> FinboySlick: nothing has changed. Autocad 2013 is kind of the gold standard, REVIT is a hot piece of flaming thrash
[21:39:19] <humble_sea_bass> I like Draftsight. it is an ACAD clone from 3dSystemmes
[21:39:34] <zeeshan> i use both inventor and solidworks daily
[21:39:39] <zeeshan> and theres a few features missing from one or another
[21:39:42] <zeeshan> but nothing major
[21:39:56] <zeeshan> i think modern cad systems have gotten a lot better since 2006
[21:40:02] <zeeshan> you can do a lot more now
[21:40:06] <CaptHindsight> and the 80's
[21:40:11] <FinboySlick> Inventor might have made a lot of progress but it was always pretty toy-like to me.
[21:40:19] <zeeshan> FinboySlick: its very powerful
[21:40:47] <zeeshan> its worth learning if you're going to use it in the field
[21:41:02] <zeeshan> it won't dissapoint like freecad :D
[21:41:15] <CaptHindsight> I probably have Autocad for dos from ~85 somewhere
[21:41:38] <zeeshan> i have people at work whove been using inventor for 5 years
[21:41:54] <FinboySlick> zeeshan: Well, it's been a few years since I played with it, it's very likely better now. Back then though, it was meant to be easy.
[21:42:05] <zeeshan> and they dont know the f7 option
[21:42:06] <CaptHindsight> I think i had a version for the Mac512
[21:42:06] <Tom_itx> CaptHindsight, i finally tossed my floppies
[21:42:09] <zeeshan> to slice graphics
[21:42:21] <zeeshan> when doing complex sketches that go through a solid body
[21:42:33] <CaptHindsight> Tom_itx: a decade or so ago I backed em all onto hard drives
[21:42:52] <Tom_itx> yeah but rll isn't supported now :)
[21:43:20] <Tom_itx> i got a pile in the drawer too
[21:43:30] <Tom_itx> and dat tapes
[21:43:36] <zeeshan> its something solidworks lacks btw
[21:43:39] <zeeshan> you gotta manually section the view
[21:43:43] <CaptHindsight> I check the back pages of Computer Shopper for old HD deals :)
[21:43:43] <zeeshan> before doing the sketch
[21:44:27] <Tom_itx> i need to put the 'normal to' button on my top bar
[21:45:04] <CaptHindsight> http://www.computershopper.com/ it's not the same online :(
[21:45:20] <Tom_itx> nope
[21:45:30] <Tom_itx> no more door stops
[21:45:33] <zeeshan> you dont like the spacebar shortcut
[21:45:34] <zeeshan> to normal to?
[21:45:46] <Tom_itx> zeeshan, i'm still learning about it
[21:45:49] <CaptHindsight> and it always felt like a deal since it was as thick as a bible
[21:46:01] <zeeshan> alternative you can do
[21:46:02] <zeeshan> ctrl + 8
[21:46:07] <Tom_itx> replaced them with digikey and mouser door stops
[21:46:08] <zeeshan> ctrl 1- 8
[21:46:11] <zeeshan> plays with views
[21:46:15] <CaptHindsight> lol
[21:47:05] <CaptHindsight> pretty useless print catalogs since it's so much easier to search online
[21:47:23] <Tom_itx> i used both
[21:47:42] <Tom_itx> find a similar product then look on that page in the catalog for other brands
[21:47:53] <FinboySlick> B&H Photo is smaller but I think they crank one every 4 months.
[21:48:05] <Tom_itx> i always enjoyed brousing that one
[21:48:09] <FinboySlick> "Here's our fall catalog of the exact same shit that was in our previous catalog.
[21:48:17] <Tom_itx> yup
[21:48:47] <CaptHindsight> ever been to the B&H store in Manhattan? not really that big
[21:48:56] <Tom_itx> nope
[21:49:16] <FinboySlick> Only place I've been in Manhattan was the bus stop on my way to PA.
[21:49:52] <FinboySlick> For a kid from rural Quebec... It was pretty impressive.
[21:50:30] <FinboySlick> Is it just me or does NY City have a 'vibration' of sorts? I mean it *feels* like NY City. I'm not sure how to describe it.
[21:50:49] <CaptHindsight> yeah, I used to go just for that
[21:51:14] <CaptHindsight> lots of creative types and things to do
[21:52:39] <CaptHindsight> Tokyo is another
[21:53:00] <CaptHindsight> never a dull moment
[21:56:27] <Jymmm> like the scum crawling on your skin?
[21:58:02] <fenn> http://youtu.be/s5-30NKSwo8 "what makes paris look like paris"
[21:58:13] <CaptHindsight> I miss the NYC filth of the pre-00's
[21:58:35] <fenn> go to harbin
[21:58:39] <fenn> plenty of filth
[21:58:40] <CaptHindsight> feels to much like a suburban mall now
[21:58:43] <Jymmm> No vintage filth for you!
[22:00:31] <Jymmm> Is $26 for a 7" tablet worth it?
[22:01:35] <jdh> I have bought several tablets, cheap and not. Never found a good use for one.
[22:01:57] <Jymmm> I was thinking wall mounted control
[22:02:24] <Jymmm> like weather station, or remote camera, or streaming music
[22:04:08] <Valen> Jymmm: link?
[22:04:15] <Jymmm> Wow, not worth $26 even http://www.amazon.com/Maylong-Mobility-Tablet-Google-Android/dp/B00H95O0I2#customerReviews
[22:06:53] <Jymmm> Valen: frys promo code
[22:07:21] <Jymmm> no cameras
[22:07:45] <Jymmm> wait, maybe a camera
[22:08:44] <Jymmm> Valen: http://www.frys.com/product/8610570
[22:10:05] <zeeshan> CaptHindsight: did you ever try loading/unloading a test coupon of polymer
[22:12:02] <CaptHindsight> zeeshan: ?
[22:12:15] <zeeshan> ?!?!
[22:12:16] <zeeshan> :D
[22:12:25] <Jymmm> Mom?
[22:17:33] <CaptHindsight> zeeshan: duhnno what you mean
[22:19:56] <zeeshan> nm
[22:21:31] * Tom_itx dusts zeeshan's lathe off a bit...
[22:22:09] <zeeshan> haha low blow!
[22:29:19] <Tom_itx> what _have_ you done on it lately?
[22:31:32] <zeeshan> nothing
[22:31:34] <zeeshan> been working on the car
[22:31:48] <zeeshan> working off a japanese manual
[22:31:50] <zeeshan> so taking very long :P
[22:31:58] <zeeshan> prolly will be until end of jan till i get it done
[22:32:14] <zeeshan> looking forward to the lathe
[22:32:18] <zeeshan> will be interesting
[22:33:53] <zeeshan> what have you been upto other than learning cad :D
[22:38:35] <FinboySlick> CaptHindsight: Oh, you still awake?
[22:38:45] <Tom_itx> just curious really...
[22:38:51] <Tom_itx> nothing but work and cad
[22:39:23] <FinboySlick> http://www.magnomatics.com/pages/technology/low-ratio-magnetic-gears.htm <--- Won't that destroy the magnets?
[22:47:50] <zeeshan> round and round they go
[22:57:41] <CaptHindsight> FinboySlick: what surprises me is the efficiency they state
[22:58:01] <CaptHindsight> have to be pricey
[22:58:19] <FinboySlick> CaptHindsight: Yeah. I'm curious to hear what andy would have to say about it, sounds like his cup'o'tea.
[22:58:41] <FinboySlick> CaptHindsight: They have a job opening... Sounds like a 3 man shop :P
[22:59:11] <CaptHindsight> but the average induction motors are in the 80's to high 90's for efficiency
[23:00:43] <CaptHindsight> I'd expect higher coupling losses
[23:01:52] <CaptHindsight> FinboySlick: they look like a new tech co trying to look legit
[23:02:42] <CaptHindsight> invest in us
[23:03:06] <FinboySlick> Yeah. I think it's interesting though. Especially the electric motor to cvt scenario.
[23:03:19] <PetefromTn_> maybe I need a site like that ;)
[23:03:38] <CaptHindsight> with an advisory board
[23:04:18] <CaptHindsight> with at least 4 poobahs, and vice-poobah and a grand-poobah
[23:04:53] <CaptHindsight> PetefromTn_: I'd be happy to design the official hats worn by the board as well
[23:05:43] <PetefromTn_> you really think I am a joke here huh sheesh
[23:06:00] <CaptHindsight> nah, just in good mood
[23:06:09] <PetefromTn_> I can't win for tryin :P
[23:07:20] <CaptHindsight> websites with all those sections for board members, advisers, team leaders etc come across like they are trying to hard and have no sales
[23:08:17] <CaptHindsight> it looks good to investors without tech knowledge
[23:08:47] <PetefromTn_> sometimes that is all that matters...most investors could not build a company or business if they tried LOL
[23:09:14] <zeeshan> the idea looks valid
[23:09:19] <zeeshan> looks like a good investment
[23:09:31] <CaptHindsight> I'd like to see pricing
[23:09:39] <zeeshan> prolly expensive
[23:09:43] <zeeshan> but if you see the construction
[23:09:46] <zeeshan> its very similar to amotor
[23:10:00] <zeeshan> so its prolly cheap once they get kicking
[23:10:22] <CaptHindsight> and offshore the core parts to China
[23:11:09] <zeeshan> Please forward your CV together with covering letter to: Bernadette Thackery, PA to the CEO, by email at: b.thackery@magnomatics.com or by post to:
[23:11:13] <zeeshan> youre 100% right capt
[23:11:26] <zeeshan> when your resume for a Product Development Apprentice (Test)
[23:11:29] <zeeshan> goes directly to the CEO
[23:11:35] <zeeshan> its a show for investors :)
[23:11:48] <zeeshan> good catch
[23:20:08] <PetefromTn_> Gn8
[23:26:11] <fenn> seems like one could change the gear ratio without moving any of the rotating parts by sliding the stator axially to a different setting, changing the number of poles in the stator
[23:26:27] <fenn> no need for CVT if you can quickly switch gears on the fly like that
[23:26:48] <fenn> also it looks really easy to build
[23:36:05] <Jymmm> Or... Just turn the dial

[23:39:44] <CaptHindsight> Without the losses of magnetic origin in the bearings and less end-effects caused by relatively short stack, an impressive efficiency estimated at 96% can be obtained.
