00:08.06 whitehawk brlcad finite element analysis
00:08.14 whitehawk there's a prog for it
00:08.18 whitehawk called solome
00:08.22 whitehawk or what

00:16.08 brlcad salome, from the open cascade folks
00:17.00 brlcad from what I understand, they don't actually do the FEA
00:17.24 brlcad they do the conversion from cad formats to various FEM
00:17.54 brlcad for this, we're working with Cubit from Sandia
00:17.56 brlcad http://cubit.sandia.gov/
00:18.00 brlcad much better package

00:21.03 brlcad howdy
00:21.34 brlcad whitehawk: in particular, we're hooking into cgm, testing out the connectivity and representations
00:21.37 brlcad looking pretty seamless

00:24.08 brlcad yep
00:24.13 brlcad external solvers being the key
00:24.16 whitehawk cubit is not free
00:25.33 brlcad for most everyone we've dealt with that need to do an FEA, cost is rarely the problem -- but that is a concern
00:25.51 brlcad open cascade doesn't help us a whole lot in that regard, they are free as in beer but not speech
00:27.02 brlcad from the few that have played with it, also, none have liked much about open cascade -- it's complex and poorly structured in places
00:27.14 brlcad this part might be better, of coruse
00:27.35 brlcad let's just say, patches to cinteract with them would be well received
00:27.42 brlcad we can already export iges for them
00:35.24 whitehawk i got errors from librt or tr...
00:35.37 whitehawk i might be missing something for compilation
00:35.51 brlcad tr?
00:36.03 brlcad ah, librt.
00:36.07 brlcad raytrace library
00:36.19 brlcad what error?
00:37.12 whitehawk something about tcltk
00:37.20 whitehawk undefined bla bla..
00:39.03 whitehawk ./.libs/librt.so: undefined reference to `Tcl_FirstHashEntry'
00:39.06 whitehawk like this
00:40.20 brlcad hmmm.. sounds like an ebuildism for finding/building Tcl
00:40.34 brlcad did you noticed whether Tcl was configured on or off?
00:40.46 whitehawk off
00:41.11 brlcad ah, that's likely why
00:41.32 whitehawk you mean --enable-tcl-build?
00:41.33 brlcad different versions of Tcl getting linked, missing a symbol
00:42.01 brlcad you should probably --enable-everything --disable-jove
00:42.08 brlcad yeah, that should be on
00:42.11 brlcad not off
00:49.09 whitehawk well
00:49.40 whitehawk it would be better to use stuff from the repo than the bundled with brlcad
00:49.44 whitehawk but nevermind
00:49.53 whitehawk night
00:53.17 brlcad i agree, that's where more work needs to go into the ebuild
00:53.33 brlcad so that it specifies the external deps better
00:53.46 brlcad right versions, adds the right build options, etc
01:01.20 learner is it all squished?
01:01.29 learner ~ww
01:01.30 ibot Wrong window pansie
01:47.39 Twingy cnc machine works great, I need to pick up some more collets and end mills though
01:47.57 Twingy and get crackin' on my cnc software
01:47.58 birdmun lol ... so it is a more manufactured machine?
01:48.05 Twingy hrm?
01:48.13 birdmun collets
01:48.38 birdmun i was just wondering what machine you were using ... homebuilt or purchased
01:48.58 Twingy taig 20ER-CR
01:49.43 Twingy after the rotary table it'll ring at about $2100
01:50.15 Twingy which is ridiculously cheap for a cnc machine
01:50.34 birdmun I have parts sitting right next to me to build a homebuilt machine minus the stepper controller
01:51.08 Twingy in the future if I require a larger cnc machine I will probably build my own
01:51.31 Twingy for now I just don't have the time to build one, I'm getting too far behind on my rocketry progress
01:51.59 birdmun lol
01:52.06 Twingy I will be dissapointed if I don't have my next rocet motor working by the end of the year
01:52.20 Twingy *rocket
01:52.27 birdmun amateur rocketry then?
01:52.31 Twingy of course
01:52.37 learner i will be disappointed if you don't win the ansari launch :)
01:52.39 Twingy if work were funding this I'd have much better tools
01:52.59 Twingy no way I can win that, don't have the budget or time alotment
01:53.23 birdmun pop sci or pop mech did a story on a competition in NM or somewhere similar
01:54.49 birdmun at least you work somewhere that is relevant to your hobbies
01:55.02 Twingy yes
01:55.57 birdmun i help manufacture dog biscuits
01:56.10 birdmun not a whole lotta call for cnc work there :)
01:56.26 Twingy heh
01:56.47 birdmun did you ever consider EMC to run your mill?
01:56.48 Twingy I need to get my salary up higher so I can tool up better
01:57.26 Twingy that'd require running linux
01:57.38 Twingy I'd rather just stick to a proven app like turbocnc in dos
01:57.52 Twingy linux without a heavy set of mods is a far cry from realtime
01:58.03 Twingy is just wasn't architectured with real-time in mind
01:58.47 birdmun i know little about both and as i have as yet to get a machine to work with i will know little about either
01:59.09 Twingy I will probably order my mig welder next
01:59.21 Twingy presumably sometime next month
02:00.40 Twingy I've actually been thinking more and more about aluminum rocket nozzles for this next motor, previously I completely ruled them out, but if designed correctly I think they run with a near room-temperature internal temp
02:00.52 birdmun what do you use for fuel in your rocket engines?
02:01.17 Twingy the last series were based on richard nakka's potassium nitrate dextrose solid motor design
02:01.41 Twingy this series is alot more experimental due to the lack of data in the amateur realm... propane and nitrous
02:03.22 Twingy it's got potential to become a really popular type due to just about every aspect of the motor and propellant being simple and cost effective
02:03.33 birdmun crazy to think people can buy this stuff off the shelf
02:03.44 ``Erik heh
02:03.52 ``Erik don't tell the gubmint
02:03.58 birdmun dont worry
02:04.13 birdmun as you saw earlier im no more fond of it than you are
02:04.26 birdmun at least the current leader
02:05.00 Twingy I probably won't have to interface with any sort of government regs for atleast 18 - 24 months due to the time frame I'm working on and the scale of the motor
02:05.14 birdmun kewl
02:05.55 birdmun so it just boils down to a power to weight ratio then
02:05.58 ``Erik it'd be interesting to use gasoline and something like a kitchen or bathroom cleaning agent to build a high output rocket engine
02:06.16 ``Erik lets see them outlaw gas and 'scrubbing bubbles' o.O
02:06.23 birdmun lol
02:06.27 Twingy I'm going to build a small 40-50lb thrust motor for my initial design, after that I will scale it up to 150-200lb or thereabouts
02:06.35 birdmun wow
02:07.07 ``Erik a longer burn time than the ~10s your current generation motors output?
02:07.13 Twingy I want appropximately 10:1 weight to thrust ratio
02:07.22 Twingy thrust to weight even
02:07.38 Twingy 10s? where where you the day of testing?
02:07.43 ``Erik 10g acceleration?
02:07.46 ``Erik which day of testing?
02:07.51 ``Erik heh
02:07.52 Twingy you said 10s
02:08.02 ``Erik I was there for a few...
02:08.03 ``Erik mebbe 2s
02:08.10 ``Erik heh
02:08.25 Twingy all the burns were well under 2s
02:08.33 ``Erik I remember explosions and pieces of the steel motor body detaching
02:08.44 ``Erik yeah, that's right...
02:08.55 ``Erik under 2s? I though tthe 'full burn' was pretty close to 2s
02:09.17 Twingy depends on the configuration
02:09.18 ``Erik you did some thrust graphs, right?
02:09.28 Twingy the 300lb thrust test was 0.9 seconds
02:09.30 ``Erik "bottom up"
02:09.34 birdmun http://www.aardvark.co.nz/pjet/xjet.shtml ever see this
02:10.02 ``Erik the 300lb was 'top down'? blowing combusted gas over the fuel core?
02:11.43 Twingy yep
02:12.11 ``Erik think if we told mt that we didn't think a decently performing fem program could do nozzle analysis, he'd whip one up for us? :D *duck*
02:12.24 ``Erik erm, rather, that such a program could be done in c++
02:12.25 ``Erik heh
02:12.58 Twingy alright, time for me to get organized here, back in a couple hours
02:13.06 birdmun hasta
02:13.07 ``Erik when you're done, clean my den.
02:13.07 ``Erik :D
02:17.59 ``Erik have you seen the pulse jet powered go-kart out of nz?
02:18.09 birdmun thats where that vid came from
02:18.13 birdmun prolly same guy
02:18.40 ``Erik ah, I was reading about pulse jets a few years ago, dude in nz did a gokart, a beer cooler, etc
02:18.49 birdmun he was working on an cheap knock off of a cruise missle
02:19.01 birdmun it has since strangely gone missing from his site
02:20.03 ``Erik huh, I think that is the same dude
02:20.10 ``Erik but when I looked, the jet was mounted low on the body
02:20.43 ``Erik http://www.aardvark.co.nz/pjet/images/jk11.jpg there it is, heh
02:20.49 birdmun http://www.aardvark.co.nz/pjet/gokart.htm
02:21.42 ``Erik chup
02:22.10 ``Erik hah, you're the dude from joplin?
02:22.47 birdmun aye
02:23.33 ``Erik man, why didn't I find anyone really interested in shit lik ethat when I was out there? :D
02:24.16 ``Erik http://www.aardvark.co.nz/pjet/pjafterburner.shtml
02:24.17 ``Erik o.O
02:25.43 birdmun you were here 10 yrs ago?
02:25.54 ``Erik '96-'03
02:25.57 ``Erik erm
02:26.02 ``Erik yeah, heh
02:26.07 birdmun http://www.interestingprojects.com/cruisemissile/
02:26.21 birdmun because in that time frame i was still in indiana
02:26.23 ``Erik <-- did smsu '97-01
02:26.58 birdmun born and raised in indiana
02:27.01 ``Erik that made like /. or something when the supposed 'leaning' was taking place
02:27.14 birdmun moved here in 03
02:27.21 birdmun i wouldnt be surprised
02:28.07 birdmun well im up to lesson 4 in Vol II Intro to mged
02:28.16 learner heh
02:28.33 learner fun fun
02:28.37 birdmun printed the whole thing out took a bit ... 2 pages per page tho ... had a couple jams too
02:29.24 ``Erik sean, I want to learn how to make models in brlcad, come show me by modelling my house :D
02:29.26 ``Erik *duck*
02:29.35 birdmun lol
02:29.55 learner easy, "make box arb8"
02:29.57 ``Erik don't make me outpress you o.O
02:30.05 learner all done
02:30.29 ``Erik does that do the moulding on the window sills and door jams, too?
02:30.30 ``Erik heh
02:30.39 birdmun pick pick pick
02:31.07 ``Erik :D
02:32.21 ``Erik ('sok, my competition lift is the 12oz curl)
02:32.23 learner hehe
02:32.31 learner mm.. speaking of such
02:33.30 birdmun wow ... i have a green rounded off nub in my graphical window
02:33.39 ``Erik I hit the local shop last night, the bottom shelf of my fridge is completely full of microbrew bottles
02:33.39 birdmun sarcasm :P
02:33.59 birdmun local shops are good
02:34.08 birdmun esp when they know you
02:34.12 ``Erik indeed
02:34.25 ``Erik I've talked shop with one of the brewers at springfield brewery
02:34.34 birdmun back home there was a store i could occassionally get discounts
02:34.55 ``Erik heh, I've also talked shop with the brewer at a local one, 'duclaws' (a bit big to bea micro anymore, guess they're a regional?)
02:35.12 birdmun he
02:35.14 birdmun h
02:35.26 ``Erik the dude here, he's not the brewmaster, but he does most of the work... he quit his job as a lawyer to brew, really cool guy
02:35.58 ``Erik man, open tab of a beer they call "venom"... I so should NOT have drove home that night, hehehe
02:36.13 ``Erik tap
02:37.04 birdmun stout
02:37.09 ``Erik ?
02:37.13 birdmun beer
02:37.18 birdmun stout/strong
02:37.19 ``Erik ja?
02:38.01 ``Erik what was the coffee&chocolate stout meuller had, um, 'mudhouse stout'?
02:38.18 birdmun no idea
02:38.24 birdmun not a beer drinker
02:38.55 birdmun southern comfort and mt dew
02:39.27 birdmun maybe i should say ... my stomach doesnt tend to like beer
02:39.39 ``Erik yet it can take diluded whiskey
02:40.36 birdmun who am i to complain :)
02:46.58 Twingy ug, so much work left
02:47.42 birdmun I have a fair amount to do myself but I cant complain ... all fairly easy stuff
02:48.17 ``Erik :D
02:48.20 Twingy I think I'm going to do a little more work on my cnc software tonight
02:49.11 ``Erik just the cut csg type thing, not, say, a driver?
02:49.12 ``Erik :D
02:49.21 ``Erik <-- thinks a fbsd driver for that thingy would be gnarly
02:49.45 birdmun debian is unacceptable?
02:50.07 Twingy turbocnc works just fine
02:50.16 ``Erik meh, when I have to use linux and I get the choice of which, I tend to go with debian 'testing'
02:50.44 birdmun i dont know enough to even get myself in trouble
02:50.52 birdmun well maybe
02:51.04 ``Erik yeah, but you have to boot dos to use it, twingy... unless you can get it chugging under dosemu without any hiccups
02:51.04 birdmun my current linux partition is unaccessable
02:51.45 birdmun unaccessible(?)
02:51.51 ``Erik funny, I have a machine with a dual boot config, fbsd and w2k... windows won't boot, the windows cd says the fs is damaged beyond usability, yet fbsd mounts and uses it just fine o.O
02:52.03 birdmun lol
02:52.25 birdmun been so long since i crashed it i dont recall what i killed
02:52.47 ``Erik I think I did in my windows in october or november
02:52.55 ``Erik :)
02:53.13 birdmun lol
02:53.30 birdmun i have a 100g drive w/ 60 partitioned for linux
02:53.48 birdmun i keep having to delete and save in my 40g windows partition
02:54.11 ``Erik <-- bought into the fileserver mentality many yrs ago... most boxes have just 'nuff hdd to hold the OS
02:54.50 Twingy 2 logitech mice and a 256MB stick for good measure
02:54.57 birdmun lol
02:55.03 birdmun only 256?
02:55.08 ``Erik http://i31.photobucket.com/albums/c383/reminesmeto/George_W__Bush_gj_r_177820a.jpg :o
02:55.25 Twingy all the stuff I do at home only requires ~256
02:55.27 ``Erik heh, and the machine will recognize 64m of it? :D
02:55.38 Twingy it's my little 3ghz p4 shoebox
02:55.50 birdmun ic
02:55.57 Twingy that's collecting dust for the last 5 months
02:56.07 birdmun i have a system like that
02:56.16 ``Erik 3ghz? damn, heh
02:56.25 birdmun via 1gig w/ 512mb and a 300g hdd
02:56.32 Twingy I've got a 1.3ghz celeron in the garage for the cnc machine, 4GB win98, 16GB fbsd6
02:56.43 Twingy with a 15" lcd
02:56.47 birdmun kewl
02:56.56 Twingy the other 15" lcd is upstairs at top of stairs
02:57.05 Twingy that's where the 3ghz box will go
02:57.13 Twingy 384MB for web/email
02:57.26 birdmun im considering a lcd for the via system
02:57.39 Twingy I absolutely love the 15" lcd's they are so practical
02:58.02 birdmun system will be used by gf's daughter
02:58.08 Twingy they're light, cheap, and can play HD video
02:58.23 birdmun dont know if 15 will really compare .. gf has 17crt and i have 19
02:58.25 Twingy my bran new 15" dell lcd was $100
02:58.32 birdmun nice
02:58.57 Twingy you just can't beat that
02:59.18 Twingy the workstation I'm on now is a pair of 19" lcd's
02:59.23 Twingy I've had this setup for 2 years
03:00.03 Twingy when I upgrade next year I will probably consolidate to one LCD since they are going way down in price
03:00.15 birdmun nice
03:00.29 Twingy the 24" ones
03:00.35 birdmun dell 20" for 459
03:00.46 Twingy these were $485 a piece in '04
03:01.51 birdmun im sure
03:02.25 Twingy once I get the 4x8 trailer together I should be ready to pick up the grizzly lathe
03:02.26 birdmun viewsonic 19" 4ms 344
03:02.35 birdmun kewl
03:02.53 Twingy they've got a cheap $2300 belt lathe I got my eye on
03:03.04 birdmun 800 dell 24 lcd
03:03.09 birdmun cheap?
03:03.16 Twingy relatively speaking
03:03.24 Twingy for a lathe that's cheap
03:03.39 birdmun i guess 2300 and cheap rarely coincided for me
03:03.39 Twingy amusing thing is it will be as much as my cnc mill
03:03.47 Twingy except lathe is 1200lbs and mill is ~100lbs
03:04.53 birdmun lathe could prolly eat the mill for breakfast
03:05.07 ``Erik heh
03:06.39 Twingy more than likely I will put down hardwood in the living room before purchasing the lathe
03:06.54 Twingy that is something I'm itching to get done
03:07.03 birdmun understandable
03:07.36 Twingy I'm thinking about picking it up sometime this month
03:08.02 Twingy the weather is a little more forgiving now that spring is near
03:08.27 Twingy no scheme, just be smart and motivated
03:08.38 birdmun i dont doubt that
03:08.55 birdmun and a much better paying job than i have
03:09.08 birdmun more motivation than anything tho
03:09.44 Twingy obviously you're content with it "enough" otherwise you would have found something else
03:10.31 birdmun actually still going to school
03:10.37 birdmun dont need to shake things up
03:11.11 birdmun and my pay is decent compared to most jobs i have had down here
03:11.20 birdmun actually all other jobs i have had down here
03:11.35 birdmun just bought a house
03:12.11 Twingy good investment
03:12.13 birdmun if i seem to be knocking you and your motivation i am sorry
03:12.25 birdmun i know im a sloth
03:12.29 Twingy heh
03:12.55 Twingy you'd be surprised how motivated and productive you can become without a girl friend :)
03:13.21 Twingy I'm just taking advantage of the situation while I've not attached
03:13.33 Twingy s/I've/I'm
03:14.36 birdmun mine is sleeping on the futon currently
03:14.55 birdmun and i am amazingly undermotivated often
03:15.09 birdmun i work hard to do what i want and then lounge
03:16.22 birdmun i have known ppl that say they cant be out of work for long ... me .. i could find many things to occupy(?) my time if i werent working
04:11.27 Twingy nothing says fun like a diamond monkey: http://www.js.cx/~justin/cornelius_diamond.png
04:11.46 Twingy http://www.js.cx/~justin/images/cornelius_diamond.png
04:13.49 learner :)
04:15.20 learner my what a mighty bulge he's got going there
04:17.00 Twingy hahaha
04:17.10 Twingy I just found a video of my room-mate firing up the old sun 3/60 we found
04:17.18 Twingy and it checking all 8MB of ram
04:18.09 Twingy excuse me a sun 3/200
