| fenn | if you sed -i 's/.*include//' headers.txt you'll get a list which you can then diff to actuals.txt | 00:11 |
| fenn | but it doesn't match what I have, curiously | 00:11 |
| fenn | (mine is more complete?) | 00:11 |
| kanzure | more files? | 00:12 |
| fenn | i guess. its the same source right? | 00:12 |
| kanzure | yes | 00:12 |
| fenn | need to go to bed soon, i'm getting tired of this anyway | 00:12 |
| * fenn finishes his primate duties on OM | 00:13 | |
| kanzure | flinging poo at people? | 00:13 |
| fenn | not in the poo flinging mood, sorry | 00:19 |
| fenn | san antonio.. blegh | 00:20 |
| kanzure | wait, if you don't want to do that, don't | 00:21 |
| kanzure | steve langford just randomly emailed me, I don't have much of an obligation to him | 00:21 |
| kanzure | also you didn't go over how much time you think I should be spending at the fabratory, but that's another issue | 00:22 |
| fenn | i have $40 and a nice odd-job is welcome right now | 00:22 |
| fenn | Les is all booked up for the rest of the month with stupid woodworking jobs | 00:23 |
| fenn | so i dont see how anything is going to happen there | 00:23 |
| fenn | i told him the first week that he's the SPOF | 00:23 |
| kanzure | hah | 00:23 |
| kanzure | do you have a key yet? | 00:23 |
| fenn | he seemed to think that was a good thing | 00:23 |
| fenn | no | 00:23 |
| kanzure | yep, he's definitely a spof then. | 00:23 |
| fenn | he wont give me a key until i sign a contract saying i have certain responsibilities etc which havent actually been thought through | 00:24 |
| kanzure | well this sucks. | 00:25 |
| fenn | anyway i couldnt build rooms and sort everything by myself | 00:27 |
| fenn | since i dont know what 80% of it is | 00:27 |
| kanzure | I have problems with visual identification | 00:27 |
| kanzure | although not with daily familiar things I guess | 00:27 |
| fenn | no, most of these things are just boards with holes drilled in them, or pencil marks or something | 00:30 |
| fenn | and i cant tell the difference between these important "references" and the piles of scrap right next to them | 00:31 |
| fenn | then there's stuff like "scrape the rust off the ceiling" which involves getting scaffolding etc | 00:32 |
| fenn | besides being a possibly worthless huge waste of time | 00:32 |
| fenn | so.. one of these days i'll actually get around to doing some electronics development | 00:33 |
| kanzure | is there an internet connection yet? | 00:33 |
| fenn | someone on craigslist has 1000's of laser printers so i'll be getting one of those for PCB stuff | 00:33 |
| fenn | no net connection | 00:33 |
| kanzure | kinda hard to do programming without a net connection. it's possible, but a pain in the ass. | 00:34 |
| fenn | not too bad with microcontrollers, actually | 00:34 |
| kanzure | say that when you're on line 13,000 of your assembly code :p | 00:34 |
| fenn | i could do a lot of it here, i'm just lazy or something | 00:34 |
| fenn | "i have a perfectly good electronics bench at the shop, why would i take half of it back to the house?" | 00:35 |
| fenn | sorta reminds me of school | 00:35 |
| fenn | constantly fiddling with schedules | 00:35 |
| fenn | i'll just get up the electronics bench in my car | 00:38 |
| fenn | that way it'll be at the shop and the house :\ | 00:38 |
| kanzure | I think *** glibc detected *** python: double free or corruption (!prev): 0x0aa54c08 *** | 00:40 |
| kanzure | is why it freezes, when I comment out the import OCC.NIS line. | 00:41 |
| fenn | it shouldnt do that if you're just missing a module | 00:41 |
| kanzure | this is another additional error methinks. | 00:41 |
| fenn | should say something like undefined reference to OCC.NIS.blargh | 00:41 |
| fenn | run python in gdb and do a backtrace | 00:42 |
| kanzure | how do I do that? | 00:42 |
| fenn | get gdb, type gdb python foo.py | 00:42 |
| fenn | then type run | 00:42 |
| kanzure | gdb | python b ? | 00:42 |
| kanzure | oh. | 00:42 |
| fenn | then when it breaks, type backtrace | 00:42 |
| kanzure | "/home/bryan/manufacturing/pythonocc/pythonOCC/Tools/InteractiveViewer/InteractiveViewer.py" is not a core dump: File format not recognized | 00:42 |
| fenn | uh. maybe ./foo.py | 00:43 |
| kanzure | file format not recognized | 00:43 |
| fenn | hm | 00:43 |
| fenn | gdb python | 00:44 |
| fenn | import foo | 00:45 |
| kanzure | how do I write in non-DOS mode in vim? | 00:45 |
| fenn | there's some pdb thing too | 00:45 |
| fenn | set fileformat=unix ? | 00:46 |
| kanzure | thank you | 00:46 |
| kanzure | huh, I need to get TkOpenGL | 00:47 |
| fenn | the dreaded Togl? | 00:48 |
| kanzure | mgltools-opengltk | 00:48 |
| fenn | what's that? | 00:49 |
| kanzure | blah, wrong. | 00:49 |
| fenn | Togl isnt packaged for debian, despite numerous apps relying on it | 00:49 |
| fenn | not sure why | 00:49 |
| fenn | i could bt wrong, maybe its not togl | 00:49 |
| fenn | ok bedtime for me | 00:51 |
| fenn | g'nite | 00:51 |

| fenn | where the hell is libTKOpenGl.so from? | 12:29 |
| fenn | that must be some library built by pythonOCC | 12:29 |
| kanzure | it might be from OCC | 12:31 |
| kanzure | it's *not* from TOGL. | 12:31 |
| xp_prg | fenn probably part of opengl | 12:32 |
| kanzure | " | 12:33 |
| kanzure | " | 12:33 |
| kanzure | Opencascade 6.3 hit Debian main three days ago, so installing OCC | 12:33 |
| kanzure | should be considerably easier from now on." | 12:33 |
| kanzure | btw, you might want to try checking out the latest version of pythonocc. that might have a few fixes, but it might also not. I did it this morning a few hours ago. | 12:36 |
| fenn | hey he's right | 12:36 |
| kanzure | yes, I noticed it in apt-cache yesterday, but there were some conflicting packages with 6.2 or something? | 12:37 |
| fenn | i must have apt-get updated at the same time i added opennovation.net repositories | 12:37 |
| kanzure | would that have caused a problem? | 12:37 |
| fenn | probably not | 12:37 |
| kanzure | opennovation.org ? | 12:37 |
| fenn | it's the same package maintainer | 12:37 |
| fenn | though you wouldnt know it from looking at the metadata | 12:38 |
| kanzure | when are you leaving for san antonio? | 12:39 |
| kanzure | hm, Todd Huffman is landing in Austin today | 12:40 |
| kanzure | http://www.genomicon.com/2009/03/theo-janssen-meets-segway-on-a-very-dark-night-indeed/ "theo janssen meets segway". oh god. | 12:41 |
| kanzure | isn't that going to be incredibly slow? | 12:41 |
| fenn | san antonio thing fell through today, postponed until tomorrow (not my fault) | 12:53 |
| fenn | they're sitting down on it because it doesn't actually balance like a segway would | 12:58 |
| fenn | todd++ http://www.flickr.com/photos/oddwick/3016657700/ | 13:24 |
| kanzure | doesn't he do contracting for DARPA? O.o | 13:28 |
| kanzure | http://groups.google.com/group/ubuntu-austin ooh, 50 members | 13:29 |
| bkero | kanzure: LUG? | 13:30 |
| fenn | UUG | 13:31 |
| kanzure | bkero: There is an Austin LUG though, yes. | 13:31 |
| kanzure | fwd'd to fenn and robotgroup. | 13:31 |
| bkero | loog | 13:33 |
| kanzure | ? | 13:33 |
| * bkero shrugs | 13:33 | |
| bkero | Banging my head against this Analysis of Algorithms class | 13:33 |
| kanzure | the answer is always O(nlog(n)) | 13:34 |
| bkero | Except when it's not. | 13:34 |
| samrose | python wrappers exist for brl-cad? | 13:34 |
| kanzure | samrose: no, but brlcad has a Tcl/Tk scripting interface via mged | 13:34 |
| * kanzure goes to class. | 13:36 | |
| fenn | lol python wrappers for brlcad! you must be joking | 13:39 |
| fenn | those guys would roll over and die if you made them use anything newer than 30 years old | 13:39 |
| samrose | fenn: I think they would be cool with someone else making it | 13:44 |
| samrose | python wrappers for brl-cad that is | 13:44 |

| kanzure | I'm so confused. | 16:39 |
| kanzure | for instance, how do I go about figuring out where whatever's being currently selected is put? probably something to do with OCC.SelectMgr, but still.. | 16:39 |
| * fenn is still slogging through responding to paul's mail... :P | 16:44 | |
| kanzure | ugh, segfault | 16:53 |

| fenn | hm so much for going to the scrapyard today | 17:04 |
| fenn | damn internet | 17:04 |
| -!- xp_prg [n=xp_prg3@99.2.31.217] has joined #hplusroadmap | 17:05 | |
| kanzure | so I'm trying to look at heekscad source in an attempt to figure out what OCC functions I'm supposed to be interested in | 17:13 |
| kanzure | but SelectMode.cpp is entirely made up of calls to wx for x/y/mouse position, nothing about objects from OCC. | 17:14 |
| kanzure | wxGetApp().FindMarkedObject(wxPoint(event.GetX(), event.GetY()), &marked_object); | 17:14 |
| kanzure | wxGetApp().FindMarkedObject(wxPoint(event.GetX(), event.GetY()), &marked_object); | 17:14 |
| kanzure | all I want to figure out is how to select stuff :-/ | 17:15 |
| fenn | what are you looking for exactly? | 17:15 |
| kanzure | grep -H -I "mouse" * | 17:15 |
| kanzure | well, display.Context_handler.SelectModeEdge suggests that this might be the general area for where to find a reference to the object that I currently have selected/highlighted in pythonocc's display window (it has some edge highlighting thingy, you see) | 17:15 |
| fenn | i think SelectModeEdge would pick an edge, not an object | 17:17 |
| kanzure | that's fine, I'm able to highlight an edge | 17:17 |
| fenn | ok, great, what's the problem? | 17:17 |
| kanzure | I want to get that object into my python script :) so that I can mess with it :) | 17:17 |
| kanzure | SelectModeEdge sets mode. | 17:18 |
| fenn | right | 17:18 |
| fenn | uh, where's the source you're running? | 17:18 |
| fenn | (on a side node, why is it Display2d.cpp and not Display2d.py?) | 17:19 |
| kanzure | source? what? | 17:19 |
| kanzure | I just loaded up a random .stp file I had laying around | 17:19 |
| kanzure | (there's a button to "load file") | 17:20 |
| kanzure | actually. one moment. | 17:20 |
| fenn | is it OCCviewer.py? | 17:20 |
| kanzure | InteractiveViewer.py | 17:20 |
| fenn | cos i dont see SelectModeEdge anywhere in there | 17:20 |
| kanzure | heh, it won't be | 17:20 |
| kanzure | "display" is the main object for the Display3d thingy, it's how you access mostly everything | 17:20 |
| fenn | oh it's new, not in the md0.1 release | 17:21 |
| kanzure | well the title on the window says md0.1 | 17:21 |
| kanzure | anyway, a script that I was playing with for STEP import: http://heybryan.org/books/Manufacturing/pythonocc/scripts/test_STEP_import.py | 17:21 |
| * kanzure goes down to eat | 17:22 | |
| fenn | well that looks pretty good.. wish i had pythonOCC :) | 17:24 |
| kanzure | by now you must have downloaded everything that you need at least once | 17:45 |
| kanzure | so now the trick is doing everything in the right order or in the right location? | 17:45 |
| kanzure | huh, my /home/bryan/manufacturing/opencascade/OpenCASCADE6.3.0/ros/ dir is the for-Windows OCC distribution. | 17:46 |
| kanzure | fenn: I'd offer to wipe my install and start fresh and document for you, but it's not clear how to uninstall as well as revert to a state where I didn't have everything laying around | 17:46 |
| fenn | yeah i hate the 'sudo python setup.py install' crap | 17:47 |
| kanzure | well, no, since I don't remember which OCC package I installed | 17:48 |
| kanzure | I ran the scons crap before I did 'python setup.py install' and I didn't run "python setup.py build' in between scons and the 'install' call | 17:50 |

| kanzure | ah here we go: http://heybryan.org/books/Biology/Multifunctional%20Nanobiomaterials%20for%20Neural%20Interfaces%20-%202009.pdf | 18:15 |

| fenn | haha "My primary goals for the software were: | 18:26 |
| fenn | Stay as far away as humanly possible from TCL. I've had dealings with frustrating languages, but this one certainly takes first prize for the worst." | 18:26 |
| kanzure | btw, the reason why I found pythonocc was because I was fed up with the solidworks api so I went off hunting for something else. | 18:30 |
| kanzure | the reason I was working with the solidworks api was because I'm redoing the gear visualizer thingy so that graphsynth exports CAD files | 18:30 |

| katsmeow-afk | fenn ? | 21:10 |
| katsmeow-afk | making a lost foam boat prop, will the foam bend in doing cnc, being that the blades are so thin? | 21:11 |
| fenn | how thin? | 21:12 |
| fenn | if they're too thin your metal won't make it to the edges of the mold | 21:12 |
| katsmeow-afk | 1/2 inch at root, tapering to nothing in 12 inches | 21:12 |
| fenn | probably too thin for casting | 21:13 |
| katsmeow-afk | so i'd be better off just milling the block of Al ? | 21:13 |
| fenn | dunno | 21:14 |
| katsmeow-afk | or cast a block i can mill the blade from, since i can get bricks of Al | 21:14 |
| katsmeow-afk | start at the narrow edges, and mill towards the root | 21:14 |
| fenn | if you're going to cast, you might as well make it roughtly the correct shape | 21:14 |
| katsmeow-afk | ok, thanks, fenn :-) | 21:14 |
| katsmeow-afk | yes | 21:14 |
| fenn | maybe a belt sander is more appropriate than CNC | 21:14 |
| katsmeow-afk | seriously? | 21:14 |
| fenn | for trimming the last little bit off, yes | 21:15 |
| katsmeow-afk | hmm, ok | 21:15 |
| katsmeow-afk | i may haveto try everything | 21:15 |
| fenn | not sanding the foam, the aluminum | 21:15 |
| katsmeow-afk | yeas | 21:15 |
| kanzure | how degrading. calculator dies in the middle of a physics test, and you're fucked since you're calculating 9 digit variables in the middle of a 4-step problem or something | 21:17 |
| kanzure | so rounding off by four digits or something isn't really useful | 21:17 |
| kanzure | and then of course they don't give you enough time if you had to manually do the calculations. blah. | 21:18 |
| fenn | did you ask for a calculator? | 21:21 |
| kanzure | no. | 21:22 |
| kanzure | in some of the classes, calculators and pencils are advertized as being available, and this one wasn't- maybe they actually had some? | 21:23 |
| fenn | well even cell phones have primitive calculators | 21:24 |
| fenn | they'd be lying if they said there were no calculators available, if you actually brought a calculator and it died | 21:24 |
| kanzure | hah, they would never let us use cell phones :) | 21:24 |
| fenn | anyway how hard could it be for a TA to dig up a calculator | 21:28 |
| katsmeow-afk | $bribe$ | 21:29 |
| fenn | shouldnt that be "\$$bribe" | 21:30 |
| kanzure | what syntax is $bribe$ ? | 21:30 |
| kanzure | $$bribe is a variable variable. "\$$bribe" is an escape character plus the value of a bribe variable. but '$bribe'? | 21:31 |
| kanzure | erm | 21:31 |
| fenn | i think you messed up | 21:31 |
| fenn | it's ok, man | 21:31 |
| kanzure | omg 1 s/but \'\$bribe\'/but \'\$bribe\$\'/ | 21:32 |
| kanzure | or however that weird chat.rb regexp system works :/ | 21:32 |

| fenn | one of les's roomate's friends is building a furnace for casting aluminum | 21:46 |
| kanzure | les has another roommate? | 21:48 |
| gene_ | kanzure, do you think anything of significance will happen with the fablab over spring break? | 21:49 |
| fenn | kanzure: there's a cat, a bird, and a guy named doug | 21:50 |
| fenn | gene_: you really ought to be asking me, since kanzure hasnt been there for 3 weeks | 21:50 |
| gene_ | so what do you think fenn? | 21:50 |
| fenn | i dont think a whole lot will happen at least until march 25 or so | 21:51 |
| fenn | bummer | 21:51 |
| gene_ | what happens on the 25th? | 21:51 |
| fenn | deadline for les' projects | 21:51 |
| gene_ | which would be? | 21:51 |
| fenn | uh, bunch of stupid jobs he got himself obligated to do | 21:52 |
| gene_ | oh | 21:52 |
| gene_ | so 1. when can we get a CNC machine | 21:52 |
| fenn | magically self-supporting bookshelves for Dell's lobby.. i forget what the others are | 21:52 |
| gene_ | 2. when can we get a lasercutter | 21:52 |
| fenn | 2. whenever you come up wiht $10k | 21:53 |
| gene_ | they have ones for $2500 | 21:53 |
| gene_ | I believe | 21:53 |
| fenn | 1. I really dont know what the hold up on this is | 21:53 |
| gene_ | what is there something moderately like a CNC machine ? | 21:53 |
| fenn | it's an exceptionally beefy 5'x10' router that's about 90% completed | 21:54 |
| gene_ | what needs to be done to complete it? | 21:54 |
| gene_ | can it cut metal? | 21:54 |
| fenn | uh, probably light milling on aluminum but i doubt les will be happy about that | 21:55 |
| fenn | there's some slight warpage in the table from when it was welded (big surprise~) so we're going to un-warp it by welding on the other side | 21:55 |
| gene_ | you got welding supplies? | 21:56 |
| fenn | and then we have to weld the gear racks into one piece (they come in 5 ft sections or something like that) | 21:56 |
| fenn | yes there's a mig welder, but i think he wanted to use an acetylene torch | 21:56 |
| gene_ | sounds like it isn't a particulary accurate mill | 21:57 |
| fenn | need to get motor mounts laser cut (dont ask me why) and drill holes for limit switch sensors | 21:57 |
| fenn | and then build the z axis, which i have no idea how it's supposed to work | 21:57 |
| fenn | really i'd rather have something smaller and simpler to start with | 21:57 |
| gene_ | gear motor mount laser cut? | 21:57 |
| gene_ | got a part file? | 21:58 |
| gene_ | what material? | 21:58 |
| fenn | i dont have any cad files for this | 21:58 |
| fenn | but they exist | 21:58 |
| fenn | 1/4" steel | 21:58 |
| gene_ | uh, I don't think you can laser cut that | 21:58 |
| gene_ | hmmmm... does it need crazy tolerances? | 21:58 |
| fenn | i'd just drill the damn thing on the drill press, but les has silly ideas about productivity | 21:58 |

| gene_ | is it all 2D? | 21:58 |
| fenn | no it just some plate you put a bolt and nut on | 21:59 |
| fenn | way too many laser cut parts in that machine | 21:59 |
| gene_ | do you have some sharpies, a DC power source, some tape, salt, water, and a big plastic container? | 21:59 |
| fenn | dude, be realistic | 22:00 |
| fenn | 1/4" steel | 22:00 |
| gene_ | it can be done | 22:00 |
| * fenn gives gene_ "the look" | 22:00 | |
| gene_ | you'd be surprised | 22:01 |
| kanzure | fenn: how would that 3rd axis be too hard? I mean, you'd have to redo the xy metal contraption thingy, but what's the big deal? take a look at oomlout's mdf 3-axis thingy. | 22:02 |
| gene_ | you can drill nice pretty holes with ECM | 22:03 |
| gene_ | if I can only find the site though... | 22:04 |
| fenn | kanzure: it's been engineered to death, that's the problem | 22:06 |
| fenn | there's this pyramid shaped thing with ovals cut out all over the place, and somehow this pringles chip thing with tabs sticking out everywhere moves up and down inside the pyramid | 22:07 |
| fenn | it's not just a nice flat surface you bolt another axis on | 22:08 |

| fenn | and this is how it fits in the machine http://www.turningaround.org/Images3/CNC3.jpg | 22:10 |
| gene_ | I found a really cool website about using piezos as a micropositioner, but it's dead :( | 22:11 |
| kanzure | " | 22:11 |
| kanzure | "Alright, so, let's start with NR2B. Also known as GRIN2B and glutamate receptor, ionotropic, N-methyl D-aspartate 2B. One of the search results on Google for GRIN2B agonists is my own 2008-03-31 page on increasing repetitive behaviors, so evidently I am going in circles again. On that other page, GRIN2B was being studied in a thalamocortical study of OCD. See also "Association of the glutamate receptor subunit gene GRIN2B with attention-deficit/hyperactivity disorder"." | 22:11 |
| kanzure | blah. My life is just this one big giant circle. | 22:12 |
| fenn | is that your first search result for GRIN2B? | 22:12 |
| fenn | you just need to set up some google alerts instead of actively searching | 22:12 |
| fenn | more Z complexity http://www.turningaround.org/Images3/CNC4.jpg | 22:13 |
| kanzure | was just reading through intense_world_syndrome.html again because I linked somebody on an AGI list to it when they discovered the Henry Markram video | 22:14 |
| kanzure | they went a little far and said that Henry deserves a Nobel Prize, but for making up statistical bullshit on the prefrontal cortex's connectivity? I don't think so :/ | 22:14 |
| kanzure | (but otherwise he's of course, awesome) | 22:14 |
| gene_ | hmmmm... | 22:20 |
| gene_ | found a russian CNC machine that cost $428 | 22:20 |
| kanzure | where are you getting that money? | 22:21 |
| kanzure | fenn: can we get dan heeks, thomas paviot, jelle feringa into this channel or om by any chance? the likelihood seems slim :/ | 22:23 |

| gene_ | hahaha, this russian CNC machine I'm looking into can operate in sub-zero conditions | 22:33 |
| fenn | FUCK | 22:38 |
| fenn | now google doesnt even AND all the search results together | 22:38 |
| fenn | they just couldn't let it be.. | 22:38 |
| fenn | i give it another 3 months before they remove the functionality entirely in the name of stupidity | 22:39 |
| gene_ | huh? | 22:40 |
| fenn | foo +bar | 22:40 |
| fenn | results won't necessarily have bar unless you add + | 22:41 |
| kanzure | I think Google transitions certain users over in bulk or something, but in batches | 22:44 |
| kanzure | because some people experience new features, others don't | 22:44 |
| kanzure | foo +bar insensitivity happens for me too. | 22:44 |
| fenn | yeah did you know amazon price is different depending where your ISP is? | 22:44 |
| fenn | so they can extract the most money out of you | 22:45 |
| kanzure | lovely. | 22:45 |
| kanzure | but that could just be done by currencies. | 22:46 |
| fenn | i mean it changes by zip code | 22:46 |
| gene_ | http://tinyurl.com/cv6aov | 22:47 |
| gene_ | looks like we have a way to make sharpie microfluidics acurately | 22:47 |
| fenn | gene a couple days ago you were in #emc asking about something.. what was that about? | 22:48 |
| fenn | that ball guide is icky | 22:49 |
| fenn | corners don't make good bearing surfaces | 22:49 |
| gene_ | that's not a ball guide | 22:50 |
| fenn | well whatever it is | 22:50 |
| -!- ybit [n=heath@unaffiliated/ybit] has quit ["Lost terminal"] | 22:52 | |
| fenn | i like this construction method (perhaps not suitable for just scratching in sharpie ink) http://buildyourcnc.com/mickhcnc.aspx | 22:52 |
| gene_ | it's some sort of reconfigurable russian CNC machine | 22:52 |
| gene_ | http://tinyurl.com/cv6aov | 22:53 |
| gene_ | wait a second | 22:53 |
| gene_ | you see a ballguide | 22:53 |
| gene_ | hmm | 22:53 |
| fenn | By developing low-cost linear guide for the designer "Kulibin" We try a lot of designs. On one of them we describe in this article, because It seems that this is an easy-to-manufacture design of ball guide | 22:53 |
| gene_ | that's not what I wanted to show you | 22:54 |
| fenn | pic of sandwiched acrylic and aluminum with ball bearings in the gaps | 22:54 |
| gene_ | well what I wanted to show you was a DIY micromanipulator | 22:55 |
| gene_ | http://tinyurl.com/asoosx | 22:56 |
| gene_ | this is better, it's the russian CNC machine | 22:57 |
| gene_ | real cheap $428 for a kit | 22:57 |
| fenn | they use stepper motors as thrust bearings. not good | 22:58 |
| gene_ | huh? | 22:59 |
| fenn | http://www.mntc.ru/wiki/images/e/e7/9401.jpg | 22:59 |
| fenn | see how the threaded rod goes right onto the stepper with nothing between | 22:59 |
| fenn | that means it's pushing on the motor's bearings | 23:00 |
| fenn | they arent designed for that, and will give a lot of slop (backlash) | 23:00 |
| fenn | which is a big deal if you are trying to do things at small scales | 23:00 |
| fenn | especially because it's not predictable with plain bearings (bushings) | 23:00 |
| gene_ | http://tinyurl.com/dbcv87 | 23:01 |
| fenn | would you really pay $428 for that? | 23:01 |
| gene_ | I see you have a point there | 23:01 |
| gene_ | it looks like the type of thing you could make from parts from home depot | 23:01 |
| gene_ | oh wait, home depot doesn't sell metric parts | 23:02 |
| fenn | don't use metric parts then | 23:02 |
| fenn | i'd at least want proper square grid beam | 23:02 |
| gene_ | the thing that is cool about this russian design is it's versatility | 23:03 |
| gene_ | and that it breaks down quite easily | 23:03 |
| fenn | what is the foil supposed to do? | 23:03 |
| gene_ | huh? | 23:03 |
| fenn | for the probe | 23:04 |
| gene_ | russian design what do you expect | 23:05 |
