[00:11:11] <r00t4rd3d> solid state relays?
[00:11:25] <r00t4rd3d> i totally guess at that
[00:14:38] <r00t4rd3d> http://www.cncguns.com/
[00:14:49] <r00t4rd3d> America, FUCK YEAH!
[00:21:07] <alex4nder> ReadError: hell yah
[00:21:14] <alex4nder> er r00t4rd3d
[03:01:40] <DJ9DJ> moin
[04:59:17] <Loetmichel> mornin'
[06:40:04] <r00t4rd3d> wood
[06:40:23] <jthornton> who makes the bamboo fly rods here?
[06:40:56] <andypugh> Mark Wendt
[06:41:03] <jthornton> ah thanks
[07:07:24] <andypugh> Gosh!
[07:07:25] <andypugh> http://youtu.be/XsCFze4zkzk
[07:09:16] <Jymmm> http://www.youtube.com/watch?v=8J-VZoyU7CY&feature=player_embedded
[07:10:01] <andypugh> Actually, this one is even more interesting: http://youtu.be/IkFdJwW_0GI
[07:10:35] <andypugh> (He has a two-handed tool that I have not seen before)
[07:10:51] <JT-Shop> just noticed the notches on the forming tool
[07:12:07] <andypugh> I have done some metal-spinning on an ordinary lathe, it's a useful method to be aware of.
[07:14:56] <JT-Shop> I've never seen a tool like the two handed one
[07:15:54] <JT-Shop> I visited a shop that makes light fixtures and they had several stations spinning the reflecters for outdoor lights
[07:18:42] <JT-Shop> they were all CNC metal spinners
[07:22:16] <Jymmm> This seems like WAY TOO MUCH EFFORT for an "air tank" http://www.youtube.com/watch?v=44cuKCCzUwk&feature=player_embedded
[07:22:28] <Jymmm> of it's size
[07:23:52] <Jymmm> JT-Shop: Is this type fuse waterproof, or do they specifically state waterproof if it is? http://www.pyrodirect.com/ecom-prodshow/058-0105-C.html
[07:24:40] <archivist> good selection of calenders on the wall of that spinning shop :)
[07:24:58] <JT-Shop> some say waterproof some say water resistant some don't say
[07:25:10] <Jymmm> JT-Shop: Also, is there something special you have to do to cut fuse? Use high flint content wire cutters? Ceramic scissors?
[07:25:21] <Jymmm> JT-Shop: Those don't say =)
[07:25:37] <JT-Shop> just normal sissors is what we use
[07:26:06] <Jymmm> I like the long burn time. Oh, hmmm, they have a "special" till they're selling just didn't know
[07:26:15] <Jymmm> tool
[07:27:57] <Jymmm> JT-Shop: They sell REAL sparklers too!!!! wohoo
[07:28:54] <Jymmm> I haven't seen real sparklers in 10+ years
[07:31:34] <Jymmm> As it is now, only one city in this County sells 'Safe and Sane' fireworks and the Fire Marshall limits the type of fireworks they sell. Usually I have to "import" them from the next county over as the rest of the cities have a ban on all fireworks
[07:33:11] <Jymmm> All the big companies, City, and the colleges used to put on a nice aerial show, now no budget for it, can't buy/use fireworks, so now the neighborhood has better aerial fireworks than the city does!
[07:33:31] <JT-Shop> I like the tektronix board, you can't contact an admin unless your logged in... you can't log in till they approve you
[07:34:14] <Jymmm> The City would shut down the freeway, and put on a show, it was just one huge drunken party on the freeway =)
[07:35:28] <Jymmm> JT-Shop: Hey, why in the hell is aluminum powder so volatile?
[07:36:00] <JT-Shop> http://xkcd.com/627/
[07:37:32] <Jymmm> JT-Shop: Heh, that's nothing. I had ALL of my users trained to Step One: reboot the computer before even thinking of calling/emailing Jim =)
[07:42:05] <ReadError> top - 14:31:43 up 56 min, 1 user, load average: 180.91, 191.73, 194.98
[07:42:20] <Jymmm> nice!
[07:42:20] <ReadError> dont fjear the load, its only asia hammering your box
[07:42:25] <ReadError> lol no not nice
[07:42:32] <ReadError> trying to mitigate this attack over port 80 ;(
[07:42:58] <Jymmm> close all ports
[07:43:47] <ReadError> lol
[07:43:51] <ReadError> http needs to be on :(
[07:44:07] <Jymmm> no it dont, use 443
[07:44:10] <andypugh> move http to port 42 :-)
[07:44:14] <ReadError> lol
[07:44:22] <ReadError> im blocking these asian /8's ;p
[07:45:13] <Jymmm> asian, russia, ukrane, etc
[07:45:39] <andypugh> Another interesting XKCD: http://xkcd.com/195/
[07:45:48] <Jymmm> Can you see any bottles in this picture? http://careytarr.com/blog/wp-content/uploads/2010/09/wine_bottling_2.jpg
[07:46:09] <andypugh> Note for example how the Ford Motor Co has as much IP-space as Africa.
[07:46:10] <ReadError> 14:35:19 up 59 min, 1 user, load average: 323.37, 247.98, 215.23
[07:46:12] <ReadError> awww yea
[07:49:15] <Jymmm> andypugh: Most 4g phones have more ip-space than africa
[07:50:11] <JT-Shop> what is load average?
[07:52:52] <ReadError> time a process has to wait
[08:01:07] <Jymmm> WTH?! http://www.youtube.com/watch?feature=player_embedded&v=B3EnGF3vXJ8
[08:04:55] <andypugh> I am not sure that brass0shelled bangers are the best idea evr.
[08:05:16] <Jymmm> andypugh: Ya think?
[08:05:42] <andypugh> I am no expert.
[08:05:50] <Jymmm> fuse, hot melt glue and .22lr shell, what's not to love?
[08:07:15] <JT-Shop> 22mm?
[08:07:51] <Jymmm> JT-Shop: 22 rifle shell
[08:08:12] <JT-Shop> yea I know but he didn't
[08:08:49] <Jymmm> oh, I stopped listening when he said firecracker using a bullet
[08:09:22] <Jymmm> Ok I lied, I stoped listen when he said wateproofing using hot melt glue
[08:10:16] <Jymmm> JT-Shop: how do you store fuse?
[08:15:04] <Jymmm> JT-Shop: do yo have one of those big yellow boxes?
[08:21:03] <Jymmm> I can't tell you how many times I've come across firecrackers with this fuse... http://www.youtube.com/watch?feature=player_embedded&v=VODSMhWnse8
[08:25:10] <JT-Shop> in a zippy bag or an old powder container for the cut ones
[08:29:56] <Jymmm> JT-Shop: so an empty metal container would work, like those empty paint cans and lid?
[08:30:32] <JT-Shop> anything seems to work, when you purchase it has no container
[08:31:11] <Jymmm> JT-Shop: Ah. I may be a pyro, but I'm a very respectful pyro =)
[08:32:14] <Jymmm> I guess an aluminum contiainer would be better =)
[08:33:28] <Jymmm> 4.5 feet/second, eeeeesh
[08:39:44] <Jymmm> I guess if are in the demolition business that would be slow
[08:39:50] <Jymmm> ^you
[09:05:35] <andypugh> That fuse seems ideal for giving you a false sense of security, until it is too late.
[09:21:35] <elmo40> *BOOM*
[09:35:06] <JT-Shop> gee wiz I think the post count should have a word factor, if that was the case Andy would have >5k posts
[09:37:26] <archivist> and 0 for me :)
[09:40:16] <ReadError> i wish our firewalls had groups for ASIA, AFRICA, and CHINA
[09:40:20] <ReadError> that would make my job much easier
[09:42:06] <elmo40> ReadError: what are you using for firewall ?
[09:42:18] <elmo40> because I am sure Cisco does that sort of stuff
[09:47:44] <ReadError> elmo40: we use juniper firewalls
[09:47:57] <ReadError> but im saying, if they had a group that contained all the ip ranges, it would be really nice
[09:49:05] <elmo40> do you have the list of IP ranges for those countries?
[09:50:42] <andypugh> elmo40: http://xkcd.com/195/
[09:50:56] <andypugh> But IP isn't stricly geographical
[09:53:44] <ReadError> elmo40: they have list
[09:53:55] <ReadError> but im saying, if they provisioned/updated the firewalls
[09:54:10] <ReadError> it would just be a matter of creating a block policy
[09:54:18] <ReadError> if the source comes from one of those groups
[10:04:33] <andypugh> seb_kuzminsky: Did you buy the Leadshine?
[10:07:57] <cradek> andypugh: surely not, it would be silly. people on the list say retrofitting is a waste of time and money compared to buying new.
[10:11:27] <JT-Shop> yea, who in their right mind would buy something cheap that works when you can buy a brand new one
[10:12:05] <Tom_itx> that's just crazy you even brought it up!
[10:13:49] <JT-Shop> I don't know why I built a worm http://imagebin.org/212239
[10:14:02] <JT-Shop> when you can pay someone else to make one for you
[10:14:44] <JT-Shop> and yes that is a hand made rivet
[10:16:29] <ReadError> hey Tom_itx
[10:16:35] <ReadError> what camera do you use?
[10:16:42] <ReadError> on your mill
[10:17:03] <Tom_itx> JT-Shop, what is that for?
[10:17:15] <Tom_itx> ReadError i've got a Nikon
[10:17:50] <ReadError> http://bgp.nu/~tom/pub/tabs-nocntl.png
[10:17:58] <ReadError> that yours?
[10:18:14] <Tom_itx> no
[10:18:20] <JT-Shop> Tom_itx: it is for removing bits of power bags from the cannon that get blown to the rear of the cannon
[10:18:35] <Tom_itx> i wondered
[10:18:46] <Tom_itx> i didn't think you were using it to dig dandelions
[10:18:54] <JT-Shop> the print is the blank for strap
[10:20:22] <Tom_itx> ReadError, that's not this is it? http://www.miketreth.mistral.co.uk/centrecam.htm
[10:22:25] <Tom_itx> JT-Shop i thought it was just an ad for Fluid Power :D
[10:22:42] <JT-Shop> LOL
[10:22:52] <ReadError> i was thinking of putting it in my Z axis
[10:22:57] <ReadError> not in the spindle
[10:22:58] <JT-Shop> well I do have lots of note pads from them
[10:23:24] <Tom_itx> those look rather handy
[10:25:02] <ReadError> anyone had experience converting a scanned part (from a flatbed scanner) to SVG or something similar?
[10:25:16] <ReadError> my dad wants to put these new handles on this knife
[10:25:38] <ReadError> so i was going to take it off, scan it on flatbed, then try to scale it properly in solidworks, make toolpath
[10:27:27] <andypugh> ReadError: I have tried. It's hard.
[10:27:46] <ReadError> figured it would be simple to monochrome it
[10:27:48] <andypugh> It's easier to draw a new profile over the image.
[10:27:51] <ReadError> then convert that some how
[10:27:53] <ReadError> ahhh
[10:28:31] <andypugh> Put the image in one layer, draw aspline or whatever over that in a separate layer
[10:57:24] <seb_kuzminsky> andypugh: i haven't, yet
[10:57:56] <seb_kuzminsky> i've talked with some friends who have extra shop space, i might put it at their place until... i don't know when
[10:58:06] <seb_kuzminsky> i
[10:58:17] <seb_kuzminsky> i'm hoping to go inspect it sometime this coming week
[10:58:38] <andypugh> Well, you get all the fun of retrofitting it then, without the boring bit of actualy using it.
[10:58:45] <seb_kuzminsky> hah
[11:00:26] <seb_kuzminsky> andypugh: i did the 'draw over a scan' trick you described, it worked well
[11:13:31] <ScribbleJ> Inkscape has a very powerful tool to create paths from a bitmap.
[11:13:35] <ScribbleJ> "Trace Bitmap"
[11:13:59] <ScribbleJ> It doesn't work for all images but when it does, it can save a ton of time.
[11:14:33] <ReadError> creates vectors?
[11:30:02] <ScribbleJ> Yes.
[12:26:20] <IchGuckLive> hi all
[12:27:06] <andypugh> Hi
[12:27:29] <IchGuckLive> B)
[12:27:58] <IchGuckLive> Aero-Tec: Mashine config ok
[12:27:59] <elmo401> IchGuckLive: any more deep sea oil leaks?
[12:28:31] <IchGuckLive> alot but not critical
[12:29:28] <IchGuckLive> elmo401: bewlow 10k barol a day noone asks
[12:30:10] <elmo401> indeed
[12:30:32] <elmo401> id like to find that 10k barrel per day 'leak' and take it for myself!
[12:30:53] <IchGuckLive> this woudt make you a ritch man
[12:31:29] <IchGuckLive> around 8k people came to visit the CNC show jesterday
[12:31:47] <IchGuckLive> oberall i think 20k on the campus
[12:36:14] <elmo401> nice turn out
[12:36:57] <elmo401> IchGuckLive: 10,000 barrels per day won't make me a 'rich' man, eh? interesting... at $100/barrel that is a fairly good DAILY income ;)
[12:36:59] <andypugh> I just found a reason not to like Inventor Fusion, and it's quite a major one. It isn't associative. So you can't change a sketch profile and have the extruded part update.
[12:37:16] <elmo401> IchGuckLive: now, where do I locate these leaking oil holes in the bottom of the ocean
[12:37:28] <IchGuckLive> elmo401: Tax and production reduces the win
[12:37:36] <elmo401> andypugh: really? that's lame. SolidWorks does
[12:37:45] <elmo401> IchGuckLive: ocean has no tax
[12:37:58] <archivist> solidworks++
[12:38:07] <andypugh> Inventor does. This is Inventor Fusion, which is aimed at a different market.
[12:38:46] <archivist> inventor when I tried it was behind solidworks
[12:38:49] <IchGuckLive> andypugh: move to a real 3D system that dont uses NURBS
[12:38:51] <elmo401> ill be like one of the founders of Facebook and claim Signapore as my residence and pay little taxes. that fucking cheating bastard. gonna make almost $4B on facebook going public and runs off to singapore to save on taxes.
[12:40:35] <IchGuckLive> monaco is best for taxes
[12:41:13] <elmo401> perfect. ill put the business in Monaco and have the business pay all my personal expenses, since ill only be a 'consultant' ;)
[12:41:14] <andypugh> IchGuckLive: Autodesk Inventor is a proper professional package, I used to be paid to drive it. Inventor Fusion is not, but does have the advantage of running native on my Mac, and is currently in free Beta.
[12:41:45] <elmo401> still, need to locate a few of these leaking wells
[12:41:50] <IchGuckLive> then you got to live with it
[12:42:52] <andypugh> Maybe I will see how I get on with FreeCAD
[12:43:20] <andypugh> To be fair to Inventor Fusion, it's very slick and I like the interface.
[12:43:43] <IchGuckLive> agree
[12:44:20] <IchGuckLive> why arend you using for masining pars like yours librecad and heekscnc
[12:44:44] <IchGuckLive> this will give you a real prof result
[12:45:03] <IchGuckLive> very good g-code and nice easy workflow
[12:45:42] <IchGuckLive> and all for nothing of cost at all with full service backround
[12:46:01] <andypugh> Well, the main reason is that I am fluent in Inventor, so can get what I want very quickly.
[12:46:09] <archivist> because no assemblies and bugs
[12:46:11] <IchGuckLive> updates weakly on all system plattforms
[12:46:21] <andypugh> (But I can't get what I want in Fusion)
[12:47:04] <IchGuckLive> i never within the last 15years i worked with autodesk
[12:47:23] <andypugh> One of the reasons I updated my Mac to a Core i5 was that FreeCAD didn't run on the 32-bit CPU in my old one.
[12:47:26] <IchGuckLive> i got my foreman licence on R10
[12:47:41] <andypugh> Inventor and AutoCAD are hugely different.
[12:48:07] <andypugh> About the only thing in common is that they are by AutoDesk
[12:48:16] <IchGuckLive> i know i got 5 free student versions every year but never installt one
[12:48:53] <andypugh> LibreCAD is 2D-only isn't it?
[12:48:54] <IchGuckLive> as we run 6k student versions of ProE a year
[12:49:04] <IchGuckLive> yes
[12:49:20] <IchGuckLive> its basicly Qcad eqaling R12
[12:49:27] <andypugh> I can only work in 3D :-)
[12:49:51] <IchGuckLive> heekscad gives you with 2 klicks the 3D part
[12:50:30] <IchGuckLive> have you seen my howto on this sketch->part->g-code
[12:50:37] <andypugh> I really didn't get on with the HeeksCAD workflow last time I tred
[12:50:51] <elmo401> GibbsCAM is not bad, for 2D.
[12:51:06] <elmo401> 3D is still a little 'odd' compared to what im used to drawing with (solidworks)
[12:51:09] <IchGuckLive> if you are on inventor-fusion stay with it
[12:51:19] <IchGuckLive> there are somany howtos on youtube
[12:51:26] <elmo401> andypugh: seems like Heeks is stuck at 0.18
[12:51:53] <andypugh> Except that Inventor Fusion can't do all that I am used to doing in Inventor. Like associative modelling, and 3/4 section view.
[12:51:59] <andypugh> Or threads, for that matter.
[12:52:37] <IchGuckLive> im on full 3D modeling so no way to get back to nurbs eytruding
[12:53:24] <IchGuckLive> workflow in ProE is the same as in the Factury get the raw part and ter it down to the part
[12:54:03] <IchGuckLive> everyones choise to do what he best can
[12:55:49] <andypugh> Yes, that's how Inventor works. And to an extent Fusion too, but you are expected to pull and push the model to change it, not type in dimensions.
[12:56:27] <andypugh> http://wikihelp.autodesk.com/Inventor_Fusion_Technology_for_Mac/enu/TP1/Help/0000-Modeling0/0001-Create_M1
[12:57:15] <IchGuckLive> in ProE if you change a dim in the 2D sketch it goes back to all the 3D parts to the hole mashine
[12:57:59] <IchGuckLive> sometimes bad output to this effect
[12:58:23] <IchGuckLive> andypugh: good idee to get this into a lesson B) :D
[12:59:38] <IchGuckLive> no pictures in the workflow bad teatching
[13:01:22] <IchGuckLive> in ProE there is a Resketch module that runs on given speed a redo to the breakpoint of your work Studens dident now this in the ground courses so they are always impresst of my speeding construction
[13:02:07] <IchGuckLive> and at the end of the First Semester there is a speed contest on one part time to beat is 2:43
[13:06:00] <IchGuckLive> ok im off have a nice sunday whre ever you are in the world
[14:50:10] <alex4nder> joe9: hey, you online?
[14:53:47] <joe9> hey, what's up? alex4nder
[14:54:03] <joe9> alex4nder: don't ask me whether i am cutting.
[14:54:59] <JT-Shop> lol
[14:55:49] <archivist> ask baby ask
[14:58:30] <archivist> funny thing for me is Im using the old manual horizontal mill most at the moment
[15:04:47] <JT-Shop> what are you working on?
[15:05:57] <archivist> using it as a power saw on scrap :)
[15:25:02] <alex4nder> joe9: did you get those bits from thinktinker?
[15:25:14] <alex4nder> er think & tinker
[15:25:48] <joe9> alex4nder: yes, i picked them from readerror. i think it was precisebits, if i am not mistaken. he placed the order.
[15:26:38] <alex4nder> yah, precisebits is just a marketing name..
[15:26:41] <alex4nder> joe9: how do they look?
[15:27:17] <joe9> i have not used them yet.
[15:27:34] <alex4nder> ok
[15:27:42] <alex4nder> well I'll order some up
[15:27:52] <alex4nder> I looked around locally, and found jack and shit
[15:28:43] <Loetmichel> hrhr, i like double sided (carpet) tape... six pieces of slate leveled... with the same tape on the machine... ;-)
[15:28:53] <Loetmichel> http://bambuser.com/v/2642805
[15:29:36] <alex4nder> no vacuum table? ;)
[15:30:06] <Loetmichel> just doublesieded tape on a plastic table ;-)
[15:30:37] <joe9> Loetmichel: that is cool.
[15:30:44] <joe9> will have to check that out myself.
[15:30:55] <joe9> cannot believe it held it so well.
[15:30:58] <Loetmichel> bad thing: in the slate are some quarz inclusions... that NOT what the TC bit likes...
[15:31:14] <alex4nder> hah
[15:32:46] <alex4nder> joe9: are you running Debian or something else?
[15:32:54] <joe9> crux
[15:33:10] <alex4nder> ah
[15:37:00] <Loetmichel> joe9: be careful when testing: i have a special carpet tape that is intended for temporaty fixing dance PVC-"carpet" to stages.
[15:37:30] <Loetmichel> it has one 15N side and a 50N side and a middle layer of paper, not plastic foil
[15:37:49] <elmo401> there is precision double sided tape. we used it a few times on our machines at work.
[15:37:57] <alex4nder> Loetmichel: does that stuff release with a heat gun?
[15:38:02] <elmo401> they guarantee 0.002" tolerance in flatness
[15:38:14] <Loetmichel> alex4nder: wit soapü and water if neccessary
[15:38:18] <Loetmichel> -ü
[15:38:27] <Loetmichel> but a heat gun will work also
[15:38:35] <Loetmichel> or 2-propanol
[15:38:40] <elmo401> yes, alcohol
[15:39:16] <mrsun> diff på ca 1mm över 4 meter vid träbyggnation, är det bra nog? :)
[15:39:33] <alex4nder> Loetmichel: I mean for release from the table.
[15:39:53] <Loetmichel> alex4nder: i use a spray can 2-propanol
[15:40:05] <Loetmichel> spray on, warit 2 min, wipe it offf
[15:40:18] <elmo401> how we did it was we used a block to stick the part on and put the block in the vice, then when done soaked the entire setup in a bucket of alcohol for a few hours.
[15:40:31] <mrsun> doh :P
[15:40:33] <mrsun> wrong channel :P
[15:40:33] <andypugh> There is stuff designed to replace spot-welding too, you probably don't want that one. 3M VHB tape.
[15:40:50] <elmo401> our part was 6" x 9" surface area. took longer then 2 min ;)
[15:40:51] <Loetmichel> 'cause the glue carrier is made of paper the alcohol can go through it and dissolve the glue underneath
[15:41:05] <elmo401> andypugh: ya, VHB rocks!
[15:41:13] <elmo401> GM uses it on their vehicle trim
[15:41:15] <alex4nder> ah
[15:41:33] <Loetmichel> andypugh; i have a tape similar to VHB in the company...
[15:41:43] <fragalot> I tried to use VHB tape for pcb milling
[15:41:50] <ReadError> so i noticed a huge difference in direction of cutting
[15:42:05] <ReadError> when i cut CCW, the finish on the inner part was much smoother
[15:42:05] <fragalot> worked great, apart from the fact that I ruined the boards trying to get them off again
[15:42:08] <fragalot> lol
[15:42:15] <ReadError> vs, CW, it was smoother on the outside
[15:42:20] <Loetmichel> one can tape a M6 nut to the wall and screw a stub in and hang your jacket on it :-)
[15:42:27] <elmo401> I saw a demo at a trade show. the guy took two pieces of 24" 3/4" I-beam, put only 2 strips, one at each end. sat the piece on top and waited 5min. then took the winch and raised both of them and started to add weights. it never released!
[15:43:07] <elmo401> ReadError: yes, Climb milling should net you a smoother finish
[15:43:23] <Loetmichel> fragalot: thats why i use the dancing carpet tape
[15:43:33] <elmo401> but if you do not have ballscrews you will get bad results ;)
[15:43:41] <Loetmichel> it has a defined difference in glue.
[15:43:55] <Loetmichel> one side has 15N to peel it off, the other 50 N
[15:44:04] <andypugh> Loetmichel: How do you telll which side is which?
[15:44:17] <Loetmichel> so you can tape it to the machine and gurantee that te workpiece has no tape on it
[15:45:00] <Loetmichel> andypugh: the side you have oben wenn fresh from the roll is tha 50N side, the one you have to peel the wax paper off is the 15N side.. Easy
[15:45:23] <Loetmichel> s/oben/open
[15:46:35] <elmo401> Loetmichel: what is the brand? have a website? I'd like to see this stuff
[15:47:01] <Loetmichel> sorry
[15:47:14] <Loetmichel> i kenw it from my ex-job (stage hand)
[15:47:24] <Loetmichel> so i asked my ex-boss to order me some
[15:48:03] <Loetmichel> was a german company, and i had to order a box full-> 50 rolls a 50m*50mm
[15:48:13] <fragalot> Loetmichel: yeah :P but the VHB was all I had lying around at the time
[15:48:14] <fragalot> xD
[15:48:22] <Loetmichel> so i have enough for lifetime, but dont know the manufactuurer ;-)
[15:49:03] <Loetmichel> wasnt dirt cheap either.
[15:49:11] <Loetmichel> the 50 rols were about 250$
[15:49:22] <fragalot> Loetmichel: VHB is like that price for a single one
[15:49:23] <fragalot> >.<
[15:49:50] <fragalot> Anyway 's getting late
[15:49:52] <fragalot> gnite all :)
[15:50:16] <DJ9DJ> gn8
[15:50:23] <Loetmichel> fragalot: i have a nylon felt tape in the company... metallized (copper nickel) and antennae structure printet on... conductin glue...
[15:50:42] <Loetmichel> one roll 33m/30cm : 800++ eur....
[15:50:49] <Loetmichel> THATS expensive ;-)
[15:50:53] <fragalot> Loetmichel: no
[15:50:56] <fragalot> that's ridiculous.
[15:51:01] <fragalot> There's a difference :D
[15:51:47] <Loetmichel> but it is worht every cent if you want to shield/damen some 100++Mhz signals ;-)
[15:51:50] <Loetmichel> dampen
[15:52:09] <Loetmichel> worth
[15:52:20] <fragalot> tin foil hats!
[15:52:44] <Loetmichel> wrong
[15:52:55] <Loetmichel> a tin foil hat would reflect the signal
[15:53:03] <fragalot> that counts as shielding
[15:53:04] <fragalot> somewhat
[15:53:11] <Loetmichel> the "felt" converts it to heat
[15:53:45] <Loetmichel> it Dampens any signal above 100Mhz and below 4GHZ about 20dB
[15:55:07] <Loetmichel> ... helps a LOT if you have to make IT-equipment Tempest-proof ;)
[15:55:54] <fragalot> :P
[15:56:02] <fragalot> Anyway I was on my way to bed
[15:56:06] * fragalot gone
[16:14:07] <Jymmm> brass screen on walls, a few ferrets (the furry kinda), and you're good to go Loetmichel =)
[16:19:31] <Loetmichel> Jymmm: i do that for a living
[16:19:51] <Loetmichel> and certified by BSI
[16:20:21] <andypugh> Shouldn't you be certifiend by DIN?
[16:21:10] <Loetmichel> bsi= german government institiute for Ssafety in the IT
[16:21:40] <andypugh> Ah, not the British Standards Institute then
[16:21:49] <Loetmichel> no
[16:22:49] <Loetmichel> we have two measurement chambers which can measure european zoning model and nato Level model
[16:22:55] <Loetmichel> and certify both
[16:27:24] <Loetmichel> so we buy off the sheldf components/computers/printers/whatever and modify them until the meet the required emnation levels.
[16:48:29] <Jymmm> Loetmichel: you're a ferret wrangler?
[16:50:29] <Jymmm> off the shelf ferrets, is that anything like the 6 Million Dollar Ferret? "We have the technology..."
[16:53:23] <syyl_> that six million dollar ferret can bite the wire harness in your car under five seconds..
[16:53:24] <gene__> Probably specially trained blact footed ferrets
[16:53:31] <gene__> Probably specially trained black footed ferrets
[16:53:37] <Jymmm> Loetmichel: And if you dont know what I mean by you making 6 Million Dollar Ferrets... http://www.youtube.com/watch?v=HofoK_QQxGc
[16:55:03] <Tom_itx> he had to be special to keep up with farrah
[16:56:27] <gene__> I met one of those once, dragging a jack rabbit a good 15 lbs bigger than he was. We had a stare-down, him just begging me to do something about it, all attitude!
[16:57:47] <gene__> He finally tired of that, grabbed that Jack by the scuff of the neck and trucked on of to whereever
[16:59:16] <gene__> can someone quote me the line in their apt-get config that will put me back on the 2.5.0 release?
[17:00:11] <andypugh> gene__: I thought you ran compiled / run in place?
[17:00:39] <andypugh> It might be easier to checkout the 2.5 branch in git, then compile that?
[17:00:55] <andypugh> git checkout origin/v2.5_branch
[17:01:12] <andypugh> make clean // make // sudo make setuid
[17:01:40] <andypugh> Actually, git pull after checkout too.
[17:02:07] <gene__> nope, never have, and with 2.6.0's touch off broken I can't get banything done
[17:02:55] <andypugh> Ah, you run 2.6 from the deb?
[17:03:12] <gene__> I'll try, but define 'origin', emc-buildbot
[17:03:24] <gene__> is where I am now
[17:04:29] <andypugh> No, if you don't have git, that's not the way. You need to edit the line in etc/apr/sources to point to 2.5
[17:05:02] <andypugh> Just follow the instructions, then probably apt-get update?
[17:05:03] <andypugh> http://buildbot.linuxcnc.org/
[17:10:52] <gene__> I changed an old sources.list.save to the 2.5 branch, then renamed it so its active, but gets a tummjy ache
[17:16:03] <ReadError> http://i.imgur.com/BsIug.jpg
[17:16:06] <ReadError> got it pretty cleaned up
[17:16:11] <ReadError> need to vectorize it though
[17:20:01] <andypugh> That looks like something easy to trace in Inkscape.
[17:20:25] <andypugh> It's only a few circles and a curve.
[17:21:16] <andypugh> However, if you monochrome that you might find that image2gcode can raster-mill it for you. Bit that's a silly way to do it.
[17:21:41] <ReadError> well
[17:21:45] <ReadError> i need to do the holes
[17:21:50] <ReadError> since theres 2 different diameters
[17:22:20] <ReadError> so ide like to convert it to something flat, so i can put it into solidworks
[17:23:39] <andypugh> Can you open the bitmap in solidworks? I think you can have a bitmap as a sketch background in Inventor.
[17:25:11] <Jymmm> Tom_itx: Yeah, she was a lil hottie
[17:26:43] <andypugh> ReadError: This looks right: http://youtu.be/KJuWDgtoImk
[17:28:02] <andypugh> ReadError: Yes, that is demonstrating exaclty what you want to do
[17:31:28] <ReadError> ah yes, it does indeed
[17:39:04] <gene__> error, doesn't stop startup of 2.5:X Error of failed request: GLXBadContextTag
[17:39:23] <gene__> Do I need a lx update on lucid?
[17:39:30] <gene__> Do I need a glx update on lucid?
[17:39:47] <gene__> or is it ignoreable?
[17:41:57] <andypugh> I can't remember.
[17:42:29] <andypugh> Google the error message? It's not a LinuxCNC error, that's X
[17:46:49] <gene__> I figured it wasThe one report from a Ubu user was old ati card related, lots of hits for W.o.W errors, aka Wine though
[17:47:18] <gene__> and the one thread left me hanging, as in building X from scratch...
[17:49:30] <andypugh> Ah, is it one of these: http://xkcd.com/979/
[17:50:11] <Tom_itx> evening folks
[17:54:06] <gene__> I may have found a fix, seems Glut isn't thread-safe and offers a link
[17:54:30] <andypugh> Glut?
[17:55:23] <gene__> http://www.opengl.org/discussion_boards/showthread.php/165059-X-error-during-GLX-initialization?p=1166462#post1166462
[17:57:01] <gene__> Basically, any thread you open to it, must do its own painting
[17:57:43] <andypugh> But why would you have that problem, and not anyone else?
[17:57:59] <andypugh> I would be tempted to hide my Xorg.conf file if I was you :-)
[17:58:52] <gene__> The code sample at that link (good Q andy) shows the right way to "void creatWindow()"
[17:59:02] <gene__> And let it regenerate it?
[17:59:42] <gene__> Or is this X that smart?
[18:01:21] <andypugh> Xorg.conf is optional now in Ubuntu, it doesn't exist by default.
[18:01:32] <gene__> The only xorg.conf I have is xorg.config.failsafe
[18:01:43] <andypugh> Ah, there goes that idea.
[18:02:20] <gene__> That error was from this machine, checking the lathe next
[18:04:06] <gene__> Don't see it on startup, and its not there on shutdown either
[18:05:12] <gene__> And this machine doesn't have an xorg.conf either, not even the failsafe version
[18:08:20] <gene__> Its a shutdown error on this machine. New clue, it is only if I use the windows close button, if I use the pulldown's quit, no error.
[18:08:48] <gene__> So you might file that away for 2.5.1
[18:13:15] <gene__> what does the keyboard t do? I thought it might be touch off, but its killed all entry
[18:16:40] <gene__> I restarted

[19:09:29] <alex4nder> hey
[19:18:35] <SolarNRG> Have any of you guys ever worked with platinum cure for molding before?
[19:20:31] <alex4nder> you mean silicone?
[19:20:42] <JT-Shop> SolarNRG: have you considered sprocket and chain for your solar tracking thingy
[19:21:08] <JT-Shop> much cheaper than gears
[19:21:23] <alex4nder> yah and forgiving
[19:21:41] <SolarNRG> you can't tap a flat bicycle gear onto a motor rotor
[19:22:04] <JT-Shop> why not?
[19:22:14] <JT-Shop> motor cycles do it
[19:22:28] <alex4nder> (and electric bicycles)
[19:22:35] <JT-Shop> aye
[19:22:46] <SolarNRG> I'm sure you're right, but if I can make my own gears that would be fantastic
[19:23:01] <alex4nder> why you always trying to piss uphill?
[19:23:09] <JT-Shop> lol
[19:23:29] <SolarNRG> Because I've bought some platinum cure now its too late to go back
[19:23:32] <alex4nder> I mean, if your goal is to make gears, that's great.
[19:23:39] <SolarNRG> I'm molding my 3d printed gears
[19:23:42] <ReadError> amazon smallparts sells gears :)
[19:24:02] <alex4nder> sup ReadError
[19:24:03] <ReadError> man i was just browsing there the other day
[19:24:03] <ReadError> tons of cool stuff :)
[19:24:11] <ReadError> got frustrated with solidworks
[19:24:25] <ReadError> so im down in the basement hitting some iron and having a beer ;p
[19:24:31] <alex4nder> nice
[19:24:32] <SolarNRG> I take it you guys aren't into molding
[19:24:34] <alex4nder> what're you making?
[19:24:40] <alex4nder> SolarNRG: I just molded some concrete
[19:24:42] * JT-Shop loves SolidWorks
[19:24:48] <SolarNRG> What did you use, latex?
[19:24:52] <alex4nder> foam
[19:24:55] <ReadError> alex4nder, well, my dad has this knife it came with a polymer grip
[19:24:55] <alex4nder> and silicone
[19:24:59] <ReadError> so i scanned it, tried to clean it up
[19:25:02] <alex4nder> ah yah
[19:25:06] <ReadError> and convert it to a 2d sketch in solid works
[19:25:16] <ReadError> but now, i want to scale it to the proper dimensions
[19:25:22] <ReadError> i can do it by a scaling factor
[19:25:38] <ReadError> but not just by saying, i want y to be 3.5"
[19:25:49] <ReadError> which sucks, the math would be possible to do
[19:25:56] <alex4nder> ...
[19:25:58] <ReadError> but i want to learn how to do it the other way as well
[19:26:01] <alex4nder> that's some basic algebra, son.
[19:26:06] <alex4nder> ah
[19:26:08] <ReadError> yea
[19:26:17] <ReadError> but i want to learn how to use solidworks well
[19:26:22] <A1Sheds> ReadError, frustrated with Solidworks?
[19:26:24] <ReadError> college got me burnt out on math ;)
[19:26:29] <ReadError> indeed A1Sheds, indeed
[19:26:32] <A1Sheds> what happened?
[19:26:33] <alex4nder> ReadError: that's elementary school. ;)
[19:26:38] <alex4nder> fractions
[19:26:43] <JT-Shop> lol
[19:27:27] <A1Sheds> the autocomplete design not working?
[19:27:27] <ReadError> A1Sheds, so i have this sketch, i made from splines and such
[19:27:32] <A1Sheds> ok
[19:27:57] <SolarNRG> silicone rtv?
[19:27:58] <andypugh> There's something I didn't expect to see on Amzon: http://www.amazon.com/dp/B004ZNYG80/ref=biss_dp_t_asn
[19:27:59] <ReadError> so i want to scale it so Y is a certain height, but scaling only allows a scaling factor
[19:28:02] <SolarNRG> What's the deal with the mix ratios?
[19:28:15] <ReadError> i tried smart dimension, it just compresses the top spline
[19:28:20] <ReadError> rather than the entire part
[19:28:35] <alex4nder> SolarNRG: read the instructions
[19:28:36] <A1Sheds> ReadError, I'd have to see how you extruded the part
[19:28:37] <JT-Shop> andypugh: finds the neat stuff
[19:28:49] <ReadError> i havnt yet A1Sheds
[19:28:52] <ReadError> its a flat 2d
[19:29:13] <ReadError> figured ide get that all nice, then extrude
[19:29:27] <SolarNRG> I tried to glue the box around with a glue gun last time and it leaked out like this: http://www.youtube.com/watch?v=89T23XBepfw
[19:29:32] <A1Sheds> have you used Solidworks much?
[19:29:33] <SolarNRG> I need help because the gluegun didn't work
[19:29:43] <SolarNRG> And I made a mess of my kitchen when tryign to mold with plaster of paris
[19:29:52] <ReadError> http://i.imgur.com/BsIug.jpg
[19:30:05] <alex4nder> SolarNRG: I used silicone caulking as a sealant.
[19:30:05] <ReadError> A1Sheds, maybe a week or so...
[19:30:12] <ReadError> but not really that long hour wise...
[19:30:17] <ReadError> just a bit here and there
[19:30:23] <A1Sheds> ReadError, that part is simple
[19:30:43] <JT-Shop> SolarNRG: I'm just glad you don't rent a house from me
[19:30:45] <ReadError> yea i got the splines and everything done nicely, its scaling it that is giving me the issue
[19:30:51] <SolarNRG> :(
[19:30:52] <ReadError> i used the sketch tool, and traced over it
[19:31:02] <alex4nder> JT-Shop: hahaha
[19:31:07] <SolarNRG> How do you stop it leaking out?
[19:31:10] <alex4nder> SolarNRG: is that a council house?
[19:31:18] <SolarNRG> yeah
[19:31:24] <alex4nder> god, fuck england
[19:31:32] <alex4nder> what happened to you guys
[19:31:39] <SolarNRG> I'm from Scotland, not England
[19:31:43] <ReadError> work sucked
[19:31:49] <alex4nder> SolarNRG: sorry 'the UK'
[19:31:52] <ReadError> spent 2.5 hours trying to mitigate this ddos over port 80
[19:32:03] <r00t4rd3d> lol
[19:32:11] <ReadError> after telling the guy look, get DOSArrest or cloudflare
[19:32:19] <ReadError> "oh its in my contract im protected from this!"
[19:32:25] <alex4nder> laf
[19:32:27] <ReadError> *facepalm*
[19:32:30] <SolarNRG> When I get the silicone cure, how do I stop it from leaking out?
[19:32:31] <alex4nder> you're a network admin?
[19:32:34] <ReadError> sundays are supposed to be calm
[19:32:35] <ReadError> sys admin
[19:32:52] <ReadError> so i added up blocking like 60 /8's
[19:33:07] <alex4nder> haha, how does that figure into is 99.9999% availability? ;)
[19:33:20] <ReadError> and he was still getting slammed, load went up to 474 at one point :)
[19:33:24] <alex4nder> hot
[19:33:29] <ReadError> yea heh
[19:34:03] <r00t4rd3d> what site?
[19:34:30] <ReadError> i duno some .dk site
[19:34:34] <JT-Shop> fucking seed tick has jaws like a shark!
[19:35:30] <ReadError> i should setup a cron job on my mac to take a snapshot of my Win7 instance i have everything running on and rsync it to my laptop
[19:35:41] <ReadError> so when i go to work i can continue on w/e i left off at the night before
[19:35:49] <alex4nder> SolarNRG: you can use silicone sealant to seal your mold.
[19:35:52] <ReadError> ide probably kill the disk fast..
[19:35:52] <andypugh> Night all
[19:35:56] <alex4nder> andypugh: night
[19:36:12] <alex4nder> I've also heard of clay.
[19:36:14] <JT-Shop> say goodnight Gracie
[19:36:20] <ReadError> im wondering how many people are going to be sick on tuesday ;)
[19:36:25] <ReadError> with diablo 3 dropping and all
[19:36:34] <alex4nder> only closet-case nerds
[19:36:44] <alex4nder> : |
[19:36:56] <ReadError> ehhh im sure we will have some at my work
[19:37:08] <alex4nder> I played SC2 beta for months, and still went to work.
[19:37:31] <alex4nder> but it's not a crawl like Diablo
[19:39:41] <ReadError> alex4nder, when i cut my other part last night, biiiiiig difference in climb vs. conventional milling
[19:39:44] <ReadError> in edge finish
[19:39:55] <alex4nder> yes
[19:40:07] <alex4nder> what kind of feet rates and spindle speeds did you use?
[19:40:10] <alex4nder> and what endmill?
[19:40:19] <alex4nder> er feed
[19:41:53] <ReadError> about 5.8in/min
[19:42:05] <ReadError> 4F 30degree RH square 0.125"
[19:42:13] <ReadError> by niagara cutter
[19:42:24] <alex4nder> this was plastic?
[19:42:27] <ReadError> on some pvc
[19:42:28] <ReadError> yea
[19:42:40] <ReadError> when i go CCW, the inside finish is nice
[19:42:46] <ReadError> when i go CW, its more "fuzzy"
[19:42:58] <alex4nder> did you just drive the entire endmill into the cut?
[19:43:04] <alex4nder> like, for the full depth?
[19:43:19] <alex4nder> because 5.8 seems really slow
[19:43:20] <ReadError> also, with the new mobo,its muuuuuuch smoother doing rapids
[19:43:28] <ReadError> i think i was missing steps
[19:43:32] <alex4nder> ah
[19:43:50] <ReadError> maybe it was faster, i think visualmill hard codes it but i manually set it also
[19:43:56] <ReadError> didnt want to take it too fast just yet
[19:44:11] <alex4nder> well if you got fuzz instead of chips, you were probably melting the plastic
[19:44:12] <ReadError> too slow i risk melting though
[19:44:14] <Valen> plastic you need to hit hard
[19:44:30] <Valen> with a knife sharp cutter if you can
[19:44:38] <ReadError> but the outside was very smooth
[19:44:50] <ReadError> on the other side of the bit
[19:45:26] <alex4nder> yah, one side is shaving thin to large, the other is chipping thick to thin.
[19:45:32] <SolarNRG> Beddy byes for Snoozey Pies!
[19:45:53] <ReadError> night
[19:46:17] <alex4nder> I think I do plastic at like 30 IPM
[19:46:49] <alex4nder> ok, fuck, time to get ready for dinner.
[19:46:50] <ReadError> oh wow
[19:46:52] <ReadError> bye
[19:48:59] <ReadError> i need a nice set of calipers
[19:49:09] <ReadError> and one of those tools that measures thickness
[20:04:07] <Valen> ReadError: calipers? ;->
[20:05:43] <ReadError> nah it looks like a C
[20:05:50] <Valen> micromiter
[20:05:53] <ReadError> yea that
[20:06:08] <ReadError> since it seems alot of my materials are actually what they should be
[20:06:21] <ReadError> +/-0.002 it seems
[20:07:04] <toastydeath> just get a really nice set of calipers
[20:07:18] <Valen> also get a crap set
[20:07:18] <toastydeath> I have a very nice set of 0-4" mics and i rarely use them
[20:07:28] <Valen> yeah, we hardly ever use them
[20:07:32] <toastydeath> but I use my calipers constantly
[20:07:41] <Valen> get water proof ones with auto off
[20:07:45] <Valen> thats most important
[20:08:12] <toastydeath> the 8" mitutoyo calipers are really nice and about 200 bucks
[20:08:39] <toastydeath> http://www.amazon.com/Mitutoyo-500-731-10-Resolution-Carbide-Tipped-Measurement/dp/B003U9VZN4/ref=pd_cp_hi_1
[20:09:17] <Valen> lol that might be a bit excessive
[20:12:30] <toastydeath> it's as accurate as the cheaper micrometers one would buy
[20:12:36] <skunkworks__> we have 0-12" micrometers we use all the time.. the digital calipers are good but if I am doing slip/press fits - dials micrometers are the best
[20:13:21] <toastydeath> you have a set of 0-12 dial mics?
[20:13:26] <toastydeath> those things are like 600 dollars each
[20:13:32] <skunkworks__> na - import
[20:14:20] <toastydeath> even the imports are 400
[20:14:28] <toastydeath> http://www.amazon.com/Mitutoyo-510-133-Indicating-Micrometer-Graduation/dp/B007PSSK5C/ref=sr_1_9?s=industrial&ie=UTF8&qid=1336957428&sr=1-9
[20:14:44] <toastydeath> per mic
[20:17:49] <ReadError> http://www.amazon.com/Mitutoyo-500-196-20-ABSOLUTE-Accuracy-Resolution/dp/B001C0ZPNO/ref=pd_sbs_indust_1/185-6503010-2384003
[20:17:53] <ReadError> those are the ones i was looking at
[20:18:02] <skunkworks__> hmm - I think they where enco... I don't remember - we have had them for a while
[20:18:33] <ReadError> i heard they are the "industry standard"
[20:18:54] <ReadError> http://www.amazon.com/Mitutoyo-293-349-Micrometer-0-25-4mm-Graduation/dp/B002SG7QEM/ref=pd_bxgy_indust_img_b
[20:18:55] <toastydeath> mitutoyo is the top dog at the moment, yeah
[20:19:20] <ReadError> i dont want to spend extra for something un necessary
[20:19:23] <ReadError> but i like nice stuff
[20:22:29] <Valen> my philosophy is buy cheap tools, then when they either break or i hurl them across the room, replace them with the best i can afford
[20:22:38] <Valen> that way you know its something you use
[20:23:01] <ReadError> well
[20:23:06] <ReadError> i have a pretty crappy set of calipers
[20:23:09] <ReadError> dial
[20:23:41] <toastydeath> i once scrapped 25,000 dollars in parts
[20:23:47] <toastydeath> because of a dial caliper
[20:24:01] <ReadError> 0_0
[20:24:03] <ReadError> go on..
[20:24:38] <Tom_itx> toastydeath that would be one part on some of the stuff we ran
[20:25:00] <Valen> this is why for some jobs calibration is important ;->
[20:25:05] <toastydeath> Tom_itx: that would have been a fifth of the cost of some of the other parts we ran.
[20:25:14] <Tom_itx> well ya
[20:25:37] <Tom_itx> there was sort of a standing rule... have 3 methods to check every dimension
[20:25:55] <toastydeath> cheap stuff that gets used often can develop damage that is not always apparent when you gauge the tool
[20:26:44] <Tom_itx> we had a lab come in and certify stuff
[20:27:00] <toastydeath> that doesn't help you when the first three parts are fine and then the inside of the thing decides to go to shit
[20:27:32] <A1Sheds> does 3 different calipers count?
[20:27:34] <toastydeath> ten parts ran and then we picked one up to go do a full check
[20:27:39] <Tom_itx> A1Sheds, no
[20:27:40] <toastydeath> and that's when we caught it
[20:28:11] <toastydeath> A1Sheds: normally it'll be something like one type of aboslute measurement tool, a go/no go or a gage, and a CMM
[20:28:35] <ReadError> do you all work together toastydeath ?
[20:28:47] <toastydeath> no, i don't work in a shop at the moment, I went back to school.
[20:29:43] <Jymmm> Howdy Y'All
[20:29:50] <toastydeath> hai dood
[20:29:50] <Tom_itx> troll
[20:30:06] <Jymmm> Tom_itx: <--- Gremlin
[20:30:16] <Tom_itx> feed me
[20:30:18] <Tom_itx> :D
[20:30:27] <Jymmm> It aint midnight yet!
[20:30:52] <Jymmm> Tom_itx: THEN we'll feed ya nd give ya a bath with the waterhose!
[20:31:56] <ReadError> anyone made a probe? or used one
[20:32:00] <Jymmm> for the record, I hate this "Fusion" food crap
[20:32:01] <ReadError> seems like it sure would be handy
[20:32:23] <Jymmm> ReadError: Ask a couple or Martians
[20:32:28] <Jymmm> s/or/of/
[20:32:48] <Tom_itx> ReadError, http://tom-itx.dyndns.org:81/~webpage/emc/probe_index.php
[20:32:53] <Jymmm> ReadError: touch probe?
[20:33:01] <ReadError> yessir
[20:33:30] <Jymmm> Tom_itx's looks like the projects I've seen around
[20:33:33] <ReadError> any pics of the meshes you have made with it?
[20:33:41] <Tom_itx> nope
[20:33:58] <Jymmm> Tom_itx: how did that work for you?
[20:34:10] <Jymmm> sensative? too sensative?
[20:34:15] <Jymmm> sloppy?
[20:34:21] <Jymmm> reliable?
[20:34:22] <Tom_itx> i have yet to use it, waiting on stuff for other stuff for the machine
[20:34:31] <Jymmm> ah, ok
[20:34:45] <Tom_itx> - half that
[20:34:48] <A1Sheds> any else worked with Comedi and EMC at the same time, same kernel?
[20:34:51] <Jymmm> yours looks it's smaller diameter than some I've seen
[20:35:08] <Tom_itx> i made one smaller and one larger one
[20:35:25] <Tom_itx> and sent one to a dude
[20:35:49] <Jymmm> Tom_itx: so the balls are glued in place?
[20:36:24] <Tom_itx> i put a spot of superglue on them but for the most part they stay in place
[20:36:55] <Tom_itx> used a ball nose same diameter as the bearing
[20:37:01] <Jymmm> Tom_itx: k, is the wire soldered that I see?
[20:37:11] <Tom_itx> yup
[20:37:19] <Jymmm> that musta been a pita
[20:37:26] <Tom_itx> not bad
[20:37:35] <Tom_itx> i made a jig and it was pretty easy
[20:37:36] <Jymmm> torch? lol
[20:38:21] <Jymmm> Tom_itx: Yeah, let me know how the different sized ones turn out when you get a chance to paly with them
[20:38:23] <Tom_itx> that's low grade silver solder
[20:38:30] <Jymmm> ah, gotch
[20:38:32] <Jymmm> a
[20:43:44] <Tom_itx> Jymmm they should be about the same really since it takes very little to break the contact
[20:48:22] <Jymmm> Tom_itx: I would think the larger would be more senseative
[20:48:30] <Jymmm> or accurate
[20:48:56] <Jymmm> I'm not sure of the word I'm looking for
[20:49:04] <Tom_itx> i know what you're saying
[20:49:16] <Tom_itx> using a longer probe would have the same effect
[20:49:19] <Jymmm> higher resolution maybe?
[20:49:22] <Jymmm> true
[20:49:27] <Tom_itx> geometry
[20:49:42] <Jymmm> "feather touch"
[20:50:48] <Tom_itx> i didn't make them out of need so it could be a while before they get hooked up
[20:51:30] <Jymmm> It's all good I've been curious since I saw them 5 years ago, I think I can wait a tad longer =)
[20:52:02] <Tom_itx> it just looked like a cool project so i made some
[20:52:09] <Jymmm> =)
[20:52:31] <Jymmm> I tink I would try my hand at the ghetto 3D Laser scanning instead
[20:53:14] <Jymmm> since all you need is a webcam, the free software and a cheap laser pointer
[20:53:51] <Tom_itx> like kenneth did?
[20:54:10] <Jymmm> I dont know what that is or what he did
[20:54:45] <Jymmm> http://www.david-laserscanner.com/
[20:54:47] <Jymmm> that
[20:56:05] <Tom_itx> http://www.users.qwest.net/~kmaxon/page/side/art9_137.htm
[20:56:14] <Tom_itx> more of a range finder than scanner
[21:00:20] <Jymmm> There is an autonomus vehicle contest put on by NASA. Some of the contestants went into fancy sensors etc. The one that got 1st Place, didn't rely upon the sensors like other did as much as focused on software solution. They were coding on the fly to make improvements
[21:00:36] <Tom_itx> not DARPA is it?
[21:00:39] <elmo40> isn't that the DARPA challenge
[21:00:43] <elmo40> ;)
[21:00:46] <Jymmm> I think it was DARPA
[21:00:57] <Jymmm> Soem guberment agency =)
[21:01:08] <elmo40> ya, a uni won last year. completed the entire course in like 14 weeks :-P
[21:01:15] <elmo40> it took a LONG time, though
[21:01:40] <elmo40> Jymmm: guberment means tax dollars... means money out of our pockets
[21:01:43] <Jymmm> Just seeing that range finder advanced PCB made me think of it
[21:02:01] <Tom_itx> elmo40, they don't just print more??
[21:02:35] <Jymmm> Just to tell me something is 10.4 feet away, this is a bit intense to me http://www.seattlerobotics.org/encoder/200110/vision39.jpg
[21:02:39] <elmo40> in the case of the US of A... they ask the Feds to 'lend them' some.
[21:03:16] <Tom_itx> Jymmm, the guy is genius
[21:03:24] <Tom_itx> look over his site
[21:03:25] <elmo40> and the Feds reach up into their imaginary money tree and say 'here ya go, prez, $1 Trillion'... that will be $50B per MONTH in interest, thank you, come again
[21:03:50] <Jymmm> Tom_itx: I'm not saying he isn't, it's just interesting to see what a pure software solution can actually do.
[21:04:23] <elmo40> that was from 2001. how is the system doing now?
[21:04:47] <Tom_itx> i'm sure he's off doing other intense projects now
[21:05:25] <ReadError> they are working on using the kinetic (360 camera) for 3d scanning i read once..
[21:07:22] <elmo40> they could do that with the Wiimote
[21:46:05] <Jymmm> Does anyone know what can deal with thermal shock the best? Clay floor tile seems to be the worse, Regular ceramic tile? Granite? Marble? soemthign else?
[21:47:16] <Tom_itx> mica
[21:49:00] <Jymmm> sounds familure
[21:49:17] <Jymmm> is that something I might find in a floor covering store?
[21:49:28] <Tom_itx> i doubt it
[21:49:34] <Jymmm> k
[21:49:51] <Tom_itx> old stoves used it as a 'window'
[21:50:02] <Jymmm> ah
[21:50:38] <Tom_itx> early electronics used it as a barrier between transistors and their heatsinks
[21:51:14] <jdhNC> I haven't seen any in 25 years?
[21:51:24] <Tom_itx> likely not
[21:51:49] <jdhNC> I recall seeing it fairly often, but don't remember what it was in.
[21:53:03] <Tom_itx> http://en.wikipedia.org/wiki/Mica
[21:53:30] <Tom_itx> http://en.wikipedia.org/wiki/File:Mikanit.jpg
[21:54:13] <Tom_itx> Thin transparent sheets of mica called "isinglass" were used for peepholes in boilers, lanterns, stoves, and kerosene heaters because they were less likely to shatter compared to glass when exposed to extreme temperature gradients.
[22:01:09] <Tom_itx> Jymmm, get some tiles from the shuttle and do your floor
[22:01:35] <Tom_itx> i think they're done with them now
[22:02:55] <Jymmm> Heh, I guess I could just hop over to Moffet Field and ask for some samples
